Mid afternoon weather for 9/30-mostly clear (scattered Cirrus) even though East Wenatchee and the surrounding mountains are visible, the air appears to be less smokey than earlier this morning. Temperatures are in the upper 60's to low 70's, BP 30.05" and rising along with slight air movement from the SW. Current conditions for 10/01-though the sky is mostly clear, dense smoke is obscuring East Wenatchee and most of the surrounding mountains from view, no precipitation in the last 24 and, as mentioned, the air quality is bad with little to no air movement. It is from the North at 0-4 mph, wind gust: out of the NNW to 11 mph, humidity 42%, dew point 40°, current freezing level is near 14,000' [yesterday, it was near 13,000'], observation time temperature was 46°, and the barometric pressure 30.03" and rising. Here are some interesting EOM stats for SEPT 1) total rain: 0.10" or, 0.25% of average. Although precipitation for the past three months has been very sparse at best (only 0.13"), the average precipitation for this area from JAN through SEPT is 5.15". Through this same time frame, we have received 5.47". 2) number of days with no precipitation: 29, 3) high BP: 30.21" on 9/12, 4) low BP: 29.62" on 9/09, 5) date with low BP and no precipitation: 29.62" on 9/09, 6) date with high BP and precipitation: 29.97" on 9/08 (0.10"), 7) average BP: 29.91", 8)average morning temperature: a) digital: 51.3°, b) official minimum: 49.4°, c) normal average low: 47° 9) low morning temperature: a) digital: 42.1° on 9/13, b) official minimum: 40° on 9/13, 10) high morning temperature: a) digital: 63.3° on 9/25, b) official minimum: 62° on 9/09 and 9/25, 11) average afternoon temperature: a) digital: 76.8°, b) official maximum: a) 78.8°, c) normal average high: 77.8°, 12) low afternoon temperatures: a) digital: 65.3° on 9/10, b) official minimum: a) digital: 69° on 9/10, and 13) high afternoon temperatures: a) digital: 85.1° on 9/05, b) official maximum: 87° on 9/07, 08, & 15. |

Even though a lengthy band of very dry air is moving SE over SE Vancouver Island, the Northern panhandle of ID, NW MT and most of WA, since yesterday, the ridge of high pressure over SW AK, the Kenai Peninsula and Kodiak Island, has moved East over the Gulf and strengthened considerably with high pressure now at the surface and aloft. By tomorrow however, this ridge of high pressure will have moved far enough East to begin affecting WA, and then from that point it is projected to become even stronger and remain over the area through mid week of next week. Meanwhile, yesterday's forecast for "a strong cold front to sweep across the region last night and today with winds out of the North at 15-25 mph with gusts up to 40 mph down the Okanogan Valley/Highlands, across the Waterville Plateau, the Wenatchee area and over into the Western Columbia Basin today", appears to have been downgraded somewhat to just "a dry cold front with winds of only 10-20 mph, and gusts up to 35 mph". Mid afternoon weather for 10/01-since earlier this morning, the smoke thinned enough to see that it is partly cloudy. Temperatures are in the low to mid 70's, BP 29.85"F along with some air movement from the South. Current conditions for 10/02-clear skies (what a vast improvement from the dense smoke of yesterday!) except for smoke from the SW to the SE, no precipitation in the last 24, the haze is light with some nice air movement. It is from the West at 7 mph, wind gust: out of the WSW to 27 mph, humidity 35%, dew point 34°, current freezing level is near 12,500' [yesterday, it was near 14,000'], observation time temperature was 60°, and the barometric pressure 29.82" and falling. |

Five days ago (9/29), it was stated that there were indications of a major change in the weather pattern on or near mid week (which would now be yesterday and today) as fall was finally expected to arrive. "The big weather changes included: gusty North to NE winds, less smoke and haze {both of which occurred yesterday}, and much cooler temperatures (this was realized last evening-near sunset-and this morning as the official low of 34° was recorded!). The cold front responsible for these "changes" is now tracking South by SE over Northern WY, SE ID, and from Lake Tahoe to NE NV. Meanwhile, high pressure at the surface (West of Vancouver Island) and aloft over the Gulf, has moved far enough East to begin affecting WA and then is projected to become stronger and remain over the area (WA) through mid week of next week. Any "wind" should be from the NW, along with a chance for some clouds sometime this afternoon. Mid afternoon weather for 10/02-clear skies (except for denser smoke from the West to the SW which then extended to the SE), temperatures are in the upper 60's to low 70's, BP 29.80"F with a nice breeze from several directions including the NW, North and NE. Current conditions for 10/03-mostly clear (scattered Cirrus from the SW to the SE), no precipitation in the last 24, the smoke/haze is light to moderate with little to no air movement. It is from the West at 3 mph, wind gust: out of the WNW to 11 mph, humidity 32%, dew point 23° (yesterday, the reading was 34°), current snow level is near 9000' [yesterday, it was near 12,500'], observation time temperature was 34°, and the barometric pressure 30.22" and rising.

Even though the PNW should be free from active weather through at least the week end for two reasons (first, high pressure at the surface-West of the NW tip of Vancouver Island-and aloft is forcing the storm track well North of the area (WA) over AK and The Yukon. Second, this same high pressure is now close enough to affect WA and is projected to move over the state sometime Saturday), the same cannot be said of the Northern Plains as "snow invades" the area just mentioned due to "a large area of arctic high pressure building Southward out of Canada. One of the first and most striking impacts will be felt today as heavy snowfall will spread over ND and Northern MN {with accumulations of 6-12" possible} along with 50 mph gusts that will cause blowing and drifting snow". Looking ahead to the beginning of the work week, one low pressure is shown off the coast of WA, and another over NE WA with a cold front moving West by SW over WA and Vancouver Island. Mid afternoon weather for 10/03-clear skies, temperatures are in the mid to upper 60's, BP 30.16"R along with slight air movement from the SW. Current conditions for 10/04-clear skies, although the smoke/haze is visible, it is not as dense like it was the past few days, no precipitation in the last 24, light frost was observed on the backyard and some of the roofs, and little to no air movement. It is from the North at 2-4 mph, wind gust: out of the NNW to 10 mph, humidity 32%, dew point 27°, current snow level is near 9000', observation time temperature 32°, and the barometric pressure 30.18" and falling. |

Although strong high pressure at the surface-SW of the Queen Charlottes-and aloft continues to be close enough to affect WA, it should move over the state sometime tomorrow and remain over the area through next Friday. In the meantime, the only change to the high pressure aloft appears to be in the "lower half", as yesterday it was over the Gulf region whereas now it has a pronounced NE tilt. Even though drier air is currently moving NE to SW over extreme Southern and Southwestern BC, Vancouver Island, WA, NE OR, and the Northern panhandle to SE ID (near the WY border), "the PNW has been under the influence of a strong high pressure ridge since late July. As a result, very little-if any-precipitation has fallen across the area". By contrast, snow is in the forecast for central MT {as well as other Northern Plain states} and most of WY where heavy snow is likely from the NW to SE part of the state. 3-5" are expected along the East slopes of the Laramie Range including Cheyenne, whereas 8-10" are expected over the Laramie range including the I-80 summit between Cheyenne and Laramie". Mid afternoon weather for 10/04-clear skies (except for some "active smoke" near the SW horizon), temperatures are in the low to mid 60's, BP 30.09"F along with light air movement mainly from the SW, though occasionally from the NW. Current conditions for 10/05-clear skies, no precipitation in the last 24, the smoke/haze is moderate to bad, with little to no air movement. It is from the North at 2-3 mph, wind gust: out of the NNW to 11 mph, humidity 31%, dew point 27°, current freezing level is near 10,000' [yesterday, it was near 9000'], observation time temperature 31°, and the barometric pressure 30.20" and falling. |

Yesterday's long band of clouds and energy that stretched from NE of HI to AK has separated with the Northern half-having the most moisture of the two-moving moving East by NE over most of the Gulf, Eastern AK, the Yukon, and Western half of the NW Territories while the Southern half is now rotating counterclockwise around an upper level low centered NE of HI. While "winter weather advisories are in effect for Western NE and Eastern WY where 3-5" can be expected, snow is even brushing parts of the Rockies and central Plains". For example, "Harrison, NE was blanketed with a foot of new snow while Custer, SD got 9.5", and Ardmore, SD received 2". By contrast, strong high pressure at the surface-West of the Queen Charlottes-and aloft (over the Yukon, most of AK and Western NW Territories) has shifted a little further East over WA, but has been prevented from moving directly over the state because of a large trough just East of the area. This further "movement" of high pressure {mentioned above} should be realized sometime tomorrow, at which time, it is projected to remain over the area through next Friday. Mid afternoon weather for 10/05-clear skies (except for "active smoke" to the West and SW), temperatures are in the low to mid 60's, BP 30.13"F along with light air movement from the SE. Current conditions for 10/06-clear skies, no precipitation in the last 24, the smoke/haze is moderate to bad with little to no air movement. It is from the West at 2-4 mph, wind gust: out of the WNW to 10 mph, humidity 31%, dew point 28°, current freezing level is near 11,500' [yesterday, it was near 10,000'], observation time temperature 31°, and the barometric pressure 30.18" and falling.

While one model shows low pressure off the central OR coast, snow for the Canadian Rockies near the Jasper area and rain SE of that point, strong high pressure at the surface-West of the Queen Charlottes-and aloft (over most of AK, the Yukon, and NW Territories) has finally moved over WA and is expected to stay through early next week at which time it will weaken somewhat though remain over the area through the first half of the weekend. Looking ahead to next Friday, a cold front is shown moving East by SE over SW BC, SE Vancouver Island toward WA and the Northern coast of OR. Mid afternoon weather for 10/06-although the smoke over the valley is clearly visible as well as the "active smoke" on or near Mission Ridge to the SW, above this smoke-and in sharp contrast-the sky is a beautiful blue. Temperatures are in the mid to upper 60's, BP 30.03"F along with light and somewhat steady air movement from a variety of directions including the NE, South and SE. Current conditions for 10/07-clear skies, no precipitation in the last 24, the smoke/haze is moderate to bad with little to no air movement. It is from the WNW at 3-4 mph, wind gust: out of the NW to 11 mph, humidity 32%, dew point 28°, current freezing level is near 13,000' [yesterday, it was near 11,500'], observation time temperature 32° {for the past few days, the low temperatures have been about 10 degrees below the normal low for early October which are the low 40's}, and the barometric pressure 30.01" and falling. |

One model shows low pressure just West of Vancouver Island, another over SE BC, and a cold front moving South by SE over Southern ND, the NW corner of SD, and SE MT while the western end is tracking SW over Southern and SW MT. In addition, snow is in the forecast over a lengthy, narrow area including the Canadian Rockies, NW to Southern MT (as a result of the cold front-mentioned above-where "2-4" are expected in the mountains and rain in the plains and valleys") and NW to Eastern WY. However, by sometime tomorrow, a second cold front is shown moving West by SW over South central BC and Northern (Western Okanogan county) to Southeastern WA, at which point, low pressure is shown over SE WA. Meanwhile, more of the same weather as strong high pressure at the surface-in the Eastern Gulf, West of SE AK-and aloft, should remain over the area through tomorrow before it begins to break down. In the meantime, other than one precipitation event on 7/08 (0.04"), and another on 9/08 (0.10"), this area has endured 98 days without any precipitation which strongly suggests the likelihood of a drought. Why? "Because the PNW has been under the influence of a persistent strong high pressure ridge since late July. As a result, very little-if any-precipitation has fallen across the area". Current conditions for 9/08-partly cloudy (scattered Cirrus), no precipitation in the last 24, the smoke/haze is bad with little to no air movement. It is from the North at 1-2 mph, wind puff: out of the NNW to 9 mph, humidity 35%, dew point 32°, current freezing level is near 12,000' [yesterday, it was near 13,000'], observation time temperature was 35°, and the barometric pressure 29.80" and falling. |

Most of a wave is obviously influenced by the counterclockwise rotation of a very impressive upper level low-centered SE of the middle Aleutians-moving East by NE (and is believed that this wave is being prevented from moving further in this direction by a lengthy band of very dry air immediately ahead of it) toward the Gulf except for a relatively small "piece" on its SE side which looks to be calving SE over some ridging between the upper level low just mentioned and into an upper level trough {South of the upper level low off the coast of Northern CA-near the Bay area}. Looking ahead, this upper level low which has been spinning off the Northern coast of CA the past few days, should finally slide SE over the Southern CA/Northern Baja region by sometime Friday, then tracking rather quickly East by NE, it should arrive over MI by sometime Sunday. Even though high pressure still remains over the area and is in the process of breaking down, there are indications of a change for the weekend. Mid afternoon weather for 10/08-although the smoke thinned out overhead to notice that is was partly cloudy (scattered Cirrus), it is more dense near the surface and surrounding mountains. Temperatures are in the low to mid 60's, BP 29.71"F along with slight air movement from the SW. Current conditions for 10/09-partly cloudy (scattered Cirrus), no precipitation in the last 24, the smoke/haze has thinned considerably since yesterday, although the denser smoke is visible from the SW to the SE with little to no air movement. It is from the WNW at 1-3 mph, wind puff: out of the NW to 8 mph, humidity 41%, dew point 40°, current freezing level is near 12,500' observation time temperature 39°, and the barometric pressure 29.87" and falling. |

Yesterday, it was mentioned that even though high pressure still remained over the area and was in the process of breaking down, there were indications of change in the weather by the weekend. Although high pressure will remain over the area today and tomorrow, ("by the end of the work week, it will have broken down, and thus the shield from the rain should finally be gone and the next system sitting off shore will move over Western WA where heavy rain is expected for the coastal PNW through the weekend"), a major pattern change is expected across the East Pacific and Western North America for the weekend which will lead to increasing onshore flow across the PNW". At the present time, a very impressive upper level low continues to spin South of Kodiak Island. While the southern half is moving East by NE toward the West coast, the northern half is tracking North by NE over the middle to inner Aleutians, Kodiak Island and toward the Gulf, SE AK, and the Queen Charlottes. Mid afternoon weather for 10/09-although denser smoke extends from the West to the SE, the conditions over the valley and the remaining surrounding mountains have improved considerably since yesterday at this time. Temperatures are in the low to mid 70's, BP 29.71"F along with light air movement mainly from the SE, though occasionally from the South. Current conditions for 10/10-clear skies {although the denser smoke extends from the SW to the SE}, no precipitation in the last 24, the smoke/haze is still moderate to bad with little to no air movement. It is from the West at 0-2 mph, wind puff: out of the WNW to 5 mph, humidity 47%, dew point 41°, current freezing level is near 12,500', observation time temperature was 39°, and the barometric pressure 29.77" and falling. |

The big ridge of high pressure that has been in control of our weather since late July, will remain over the area today, then finally shift to the East and thus the shield from the rain should be gone, thereby allowing the next system-along with an associating cold front-off shore (currently moving East-toward the West coast-by NE over SE AK, the Queen Charlottes, North central and central BC) to move over Western WA where at first, it will produce light rainfall along the coastline, then this rain should spread inland tomorrow afternoon. However, the series coming behind it through the weekend will be packing more of a punch. For example, "a strong system will steer heavy rain into the PNW late Saturday night through possibly as late as Monday night. As a result, the lowlands/coast may see 1-4" with 1-2" of rain in the interior". Not to be outdone, "the Olympics could see as much as 4-8" of rain through Monday night". Mid afternoon weather for 10/10-even though the smokiness continues over the valley and surrounding mountains, the denser smoke continues to extend from the SW to the SE. Temperatures are in the low to mid 70's, BP 29.63"F along with light, cool air movement primarily from three directions including the East, SE, and SW. Current conditions for 10/11-despite the smokiness over the valley, the sky is clear, no precipitation in the last 24, the smoke/haze is moderate to bad with little to no air movement. It is from the WNW at 0-5 mph, wind gust: out of the NW to 13 mph, humidity 47%, dew point 37°, current freezing level is near 12,500', observation time temperature was 38°, and the barometric pressure 29.79" and rising.

The big ridge of high pressure that was in control of our weather since late July, has finally moved East of the the area which will allow "a big pattern change from this weekend through early next week and bring with it much needed rainfall, breezy winds and cooler temperatures". Meanwhile, the next system should move over Western WA where at first, it will produce light, scattered rainfall along the coastline today (one model already shows scattered rain moving East over Western WA and NW OR). For the weekend, however, precipitation will begin as light showers, increasing to downpours {"as a second front bringing heavier rain will arrive late Saturday with significant precipitation continuing Sunday and Monday"} where "rainfall will range from 2-4" along the coast, and 1-2" over the interior lowland and 3-8" in the mountains-Olympics and North Cascades". In addition, "breezy to windy conditions are also likely at times during this period, especially along the coast and in the NW interior". Later today, unfortunately, two models (GFS and NAM) show high pressure building and remaining over the area through early next week. For once, it is sincerely hoped that this trend will not materialize! Current conditions for 10/12-mostly cloudy (scattered Cirrus and Cirrostratus), no precipitation in the past 24, the smoke/haze is moderate to bad with little to no air movement. It is from the West at 2-4 mph, wind puff: out of the WNW to 7 mph, humidity 56%, dew point 40°, current snow level is near 9500' [yesterday, it was near 12,500'], observation time temperature 44° (for the past week-10/03-10/11, these morning readings have been 1 to 11 degrees below the normal low -the low 40's), and the barometric pressure 29.59" and falling. |

The amount shown above was recorded sometime during the overnight on 10/13. Although a low pressure system-centered West of Vancouver Island-along with a cold front ahead of it-tracking East by SE toward WA and OR-should move over Western WA later this afternoon bringing with it heavy rain and gusty winds, one model shows the northern section of a large wave tracking NE over SE AK, the Queen Charlottes, and most of Northern and North central BC while a much smaller southern section is moving East by NE over the central coast of and SW BC, the NW half of Vancouver Island toward WA due to a split in the "flow" as a result of a large upper level trough with an upper level low centered South of the Kenai Peninsula and a relatively "flat" ridge of high pressure over the area (WA). Mid afternoon weather for 10/13-mostly cloudy (Cirrus, Altocumulus, and scattered Cumulus), Temperatures are in the low to mid 60's, BP 29.72"F along with some air movement from the South. Current conditions for 10/14-mostly clear (scattered Cirrus, Cirrostratus, and Cumulus), the smoke/haze is light-a vast improvement over the past several days-, along with some light air movement. It is from the West at 0-2 mph, wind gust: out of the WNW to 13 mph, humidity 69%, dew point 51°, snow level is near 8000' [yesterday, it was near 9500'], observation time temperature was 49°, and the barometric pressure 29.69" and falling.

Yesterday, 0.07" was recorded from late afternoon to early evening, along with an additional 0.15" this morning for a grand total of 0.22". Although the number of consecutive days without measurable precipitation is listed (on a chart) at 84 days and ranked as the third driest period on record, the actual number of consecutive dry days for this area is believed to be 102 as only one rain event occurred on 7/08 (0.04" and a second on 9/10 (0.10"). "A strong front approaching Western WA will drag stronger winds just aloft down to the surface Monday night and early Tuesday morning followed by some cooler air behind it which will be reflected in a lower freezing level (5000' today, lowering to 4500' tonight) where snow {a total of 2"} is expected near pass level today and tonight. Meanwhile, "a strong cold front passage will usher in very windy conditions across the Columbia
Basin of Eastern WA and Northern ID. Gusts to 50 mph will be possible with the passage of the cold front this morning. This will be followed by sustained winds increasing to 25-35 mph that will last into this evening along with cooler temperatures". Looking ahead, there are indications that a very large pool of cool, dry air (currently moving East by SE over SE AK, the Queen Charlottes, central coast of BC, NW half of Vancouver Island, the coasts of WA and NW OR) could begin to affect the area-WA-by the upcoming weekend. Current conditions for 10/16-partly cloudy (scattered Cumulus), the smoke/haze is finally gone due to the very windy conditions earlier this morning and so far today. They are from the West at 10-20 mph, wind gust: out of the WSW to 42 mph, humidity 54%, dew point 32°, current snow level is near 5000' [yesterday, it was near 8000'], observation time temperature 46°, and the barometric pressure 29.38" and falling. |

The NPJ, currently just North of WA (flowing over the NW tip of Vancouver Island and SW BC) is expected to shift a little further South as a fairly potent storm will begin to move over the area tomorrow night and Friday bringing with it the possibility of some mountain snow by the weekend. Looking ahead to the weekend, there is the potential for "a surge of cold air {due to a strong cold front coming down from the Yukon late this week"} to arrive over the area (WA) by the weekend and remain through early next week. In the meantime, warmer air will start coming in tomorrow and into tomorrow night, bringing with it a warm front that will cause some rain. Heavier rain should be around the area (Western WA) by late Thursday into early Friday morning at which time, the end of the work week into the weekend should feature more of a showery period. Mid afternoon weather for 10/16-partly cloudy (scattered Cumulus-except for an area of Cumulonimbus to the NW where the precipitation is likely in the form of snow), temperatures are in the upper 50's to low 60's, BP 29.77"R along with a nice breeze from the NW. Current conditions for 10/17-mostly clear (scattered Cirrus and Altocumulus), no precipitation in the past 24, the haze is light with some light air movement. It is from the North at 0-3 mph, wind gust: out of the NNE to 11 mph, humidity 49%, dew point 33°, current snow level is 5000' rising to 6000' later this afternoon, observation time temperature was 35°, and the barometric pressure 30.03" and rising. |

Although the main storm track remained just to the North of WA {where one model shows a relatively large band of rain moving East by NE over the SE half of Vancouver Island, SW BC-NW of Vancouver-but just brushing NW WA (Olympic Peninsula), only clouds were over the Eastern Northern boundary counties of WA}, and did not shift a little to the South as expected yesterday, the rain, therefore should skirt the BC/WA border sometime this evening. Tomorrow "will start out dry as another storm system will bring increasing rain late afternoon and evening to Western WA" though warmer air will proceed ahead of tomorrow evening's rain. However by the weekend, the coldest air of the season, so far, will move in resulting in much cooler temperatures along with persistent snow at pass level. This scenario strongly suggests that the surge of cold air-mentioned yesterday-(caused by a strong cold front coming down from the Yukon late this week) now has a high probability of arriving over the area (WA) by the weekend and remaining through early next week. Meanwhile, NW of the storm track mentioned above-a very large and broad {or an upper level trough} pool of colder air is flowing SE over the inner to middle Aleutians before turning NE across the Gulf. It is believed that this "colder air" will play a role with the "surge of cold air" mentioned above. Current conditions for 10/18-mostly clear (scattered Cirrus and Cirrostratus), no precipitation in the past 24, there was heavy condensation on the gauge, the haze is light to moderate with little to no air movement. It is from the East at 0-1 mph, wind puff: out of the ENE to 5 mph, humidity 51%, dew point 38°, current snow level is 9000' [yesterday, it was near 6000'], observation time temperature was 37°, and the barometric pressure 30.03" and rising. |

The main storm track that remained just to the North of WA for the past few days, will finally "shift further South" over SW to NE OR thereby, allowing the 'surge of cold air' (caused by a strong cold front coming down from the Yukon) to "drain South eastward from BC into WA, OR, and the northern part of the Rockies and Great Basin". This cold front will bring "windy conditions to Eastern WA and portions of the ID panhandle late today and into Saturday. Sustained winds of 20-30 mph and gusts to 45 mph will be possible". Even though "a great deal of moisture will not be available, and it will not snow on the coast from Vancouver, BC to Seattle and Portland", this cold air should arrive by the weekend and remain, at least, through early next week. This will also affect the freezing level as it will be at its maximum level today and tonight (8000' and 7500' respectively) before it "crashes" to 4500' after midnight tonight. By tomorrow, it will have lowered even further to a minimum level of 3000' {where a "total of 1-7" are expected at pass level"}. In the meantime, low pressure was stated to be "off shore", while another was shown off the central coast of BC. However, the upper level low in question is actually centered West of SE AK according to the Canadian model. Current conditions for 10/19-partly cloudy (widely scattered Altocumulus and scattered Cumulus-the dominant cloud type), the haze is light to moderate with little to no air movement. It is from the West at 2-7 mph, wind gust: out of the East to 11 mph, humidity 68% (yesterday, the reading was 51%), dew point 42°, current snow level is near 8000' [yesterday, it was near 9000'], observation time temperature was 42°, and the barometric pressure 29.59" and falling. |

The coldest air so far this season, is on the way to Western WA for the weekend as an area of low pressure, currently off the coast of Southern SE AK, will slide SE near the NW tip of Vancouver Island, and with the counterclockwise rotation will not only funnel a relatively large pool of much colder and drier air-moving East by SE-over Western WA and NW OR (that yesterday was moving East by SE over SE AK, the Queen Charlottes, the central coast of BC, and the NW half of Vancouver Island) but also keep the the cool, moist air coming in right off the Pacific Ocean which should bring rain to the coast, and heavy snow to the mountains (2-4" today and tonight, for a total snow accumulation of 4-8"). In addition, the cold air should remain over the area through at least early next week. Furthermore, "behind the strong cold front that moved through overnight, very windy conditions are likely across Eastern WA and portions of the ID panhandle through early evening where sustained winds of 20-30 mph and gusts up to 45 mph will be possible. Mid afternoon weather for 10/19-partly cloudy (scattered Cirrus, Cirrostratus and Altocumulus), temperatures are in the mid to upper 60's, BP 29.44"F along with some nice air movement mainly from three directions including the SW, West, and NW on a very pleasant autumn afternoon. Current conditions for 10/20-partly cloudy (scattered Cumulus), no precipitation in the last 24, the haze is light to non existent with a nice breeze from the West. Earlier, it was from the North at 4-8 mph, wind gust: out of the NNW to 16 mph, humidity 51%, dew point 31° {yesterday, the readings were 68% and 42° respectively}, current snow level is near 3000' [yesterday, it was near 8000'], observation time temperature was 41°, and the barometric pressure 29.56" and falling. |

One model shows an extended area for snow in Southern BC, NW MT, Northern panhandle and SE corner of ID, the Cascades and northern boundary counties of WA, central and South eastern OR, NW NV and Eastern CA (including the Sierras-specifically the Lake Tahoe Basin-where not only "a wind advisory is in effect from 1PM this afternoon to 9PM this evening as winds will be 15-20 mph from the SW and gusts to 35 mph-though with ridge gusts up to 95 mph-which will result in waves of 2-3' in height, but also heavy snow (10-18" along the Sierra crest above 7000' and 4-8" below 7000'"). This "weather" mentioned above, appears to be caused by a large upper level low over the Queen Charlottes, and with its counterclockwise rotation, should funnel much colder and drier air over WA, Western OR, and Northern CA while at the same time keep the cool, moist air coming in right off the Pacific Ocean. Meanwhile, clouds and energy are moving around the Southern and SE sides of this 'very large pool of colder, drier air' over Northern CA (from over and NW of the Bay area to Lake Tahoe and beyond). Mid afternoon weather for 10/20-mostly clear (scattered Altocumulus and Cumulus), temperatures are in the low to mid 50's, BP 29.62"R along with a nice breeze from the SW. Current conditions for 10/21-mostly cloudy (scattered Cirrus, Altocumulus and Cumulus), no precipitation in the last 24, the haze is light with little to no air movement. It is from the North at 2-4 mph, wind gust: out of the NNW to 11 mph, humidity 59%, dew point 31°, current snow level is near 2500', observation time temperature 27°, and the barometric pressure 29.69" and rising. |

A trace was recorded at observation time, but since then, the amount shown above was recorded and it is still raining. A strong storm is impacting the West coast and the counterclockwise rotation of this upper level low (centered off the coast of NW Vancouver Island) is forcing clouds and energy in a North by NW trajectory over WA, Western MT, and most of OR and ID. As a result, "rain is expected across lower elevations {where one model shows a lengthy band of rain moving North by NW-from Portland to Tacoma-with more intense precipitation occurring over the Portland/Vancouver area and SW of Forks} especially in the Northern CA and Southern OR regions where as much as 2' of snow is possible in the Northern Sierra Nevada but only 4-10" in the interior NW". Closer to home, "a winter weather advisory has been issued for the East slopes of the Northern Cascades along with several locations from 2PM today through 11AM Tuesday as 2-5" are expected; however, towns below 2500' will likely see rain initially". Mid afternoon weather for 10/21-mostly cloudy (scattered Cirrus, Altostratus, and Cumulus), temperatures are in the upper 40's to low 50's, BP 29.66"R along with light air movement from the South. Current conditions for 10/22-a Nimbostratus overcast in the form of light rain, with little to no air movement. It is from the North at 0-3 mph, wind puff: out of the NNW to 9 mph, humidity 60% (at observation time), dew point 35°, current snow level is near 3000', observation time temperature 39°, and the barometric pressure 29.60" and rising. |

Yesterday morning, a trace of precipitation was recorded by observation time (7:50am). Since then however, the gauge was again checked just before the "report" was initiated (around noon) and 0.06" had been recorded. From that time until the rain stopped last evening (7:45PM), an additional 0.24" was recorded for a grand total of 0.30". Six days ago- and for the following two days-it was stated that there was a probability that a 'surge of cold air' (due to a strong cold front coming down from the Yukon late that week) would bring much colder air to the area by last weekend and remain at least through early next week {which was yesterday and today}. Well, other than the Sunday morning low of 27°, it appears that this cold air did not impact the lower valleys as much as the higher elevations where 1-2" are expected today, tonight and tomorrow on Stevens and Snoqualmie passes. In addition, a winter storm warning has been posted for the eastern mountains of Northern WA where "storm total accumulations of 6-12" are expected in the mountains above 3500', and 1-3" in valleys above 2000' "as a storm system off the SE coast of Vancouver Island will continue to bring unsettled weather from the Pacific Coast to the Rockies". Current conditions for 10/23-mostly cloudy (scattered Cirrus and Cumulus-the dominant cloud type), no precipitation during the overnight, and the haze is light to moderate with little to no air movement. It is from the West at 1-12 mph, wind puff: out of the WSW to 4 mph, humidity 73% (yesterday, the reading was 60%), dew point 36°, current snow level is near 2500', observation time temperature was 36°, and the barometric pressure 29.57" and falling.

The amount shown above was recorded by the observation time, and it is still raining! A stubborn low pressure system-off the SE coast of Vancouver Island-with its counterclockwise circulation, will continue to rotate "a train of Pacific moisture" from SE to Northern OR, and most of WA resulting in rain for the lower valleys and mountain snow in the higher elevations. As a case in point, between today and tonight, a total of 2-5" is expected on both Snoqualmie an Stevens pass due in part to the maximum freezing level being at 2500' today and tonight before commencing a gradual rise to a higher maximum level of 6000' by the weekend as a ridge of high pressure should build over the area(WA) by the weekend and remain through early next week. In addition, "a winter weather advisory has been posted where 2-5" are expected above 3000' (the heaviest snowfall should occur over the East slopes of the Cascades). Snow will develop over Chelan county this morning and gradually spread into Okanogan county before midday. The snow will continue through the evening especially North of Lake Chelan". Current conditions for 10/24-overcast (low Stratus and fog) with a steady light rain, and very little air movement. It is from the East at 0-2 mph, wind puff: out of the ESE to 9 mph, humidity 80%, dew point 37°, current snow level is 2500', observation time temperature was 39°, and the barometric pressure 29.76" and rising. |

After 0.11" had been recorded at yesterday's observation time (8:05AM), an additional 0.33" was recorded by the time the rain stopped (3:49PM) for a grand total of 0.44"! Today should be the last day of a low freezing level (3500') before undergoing a gradual rise to a higher maximum level of near 8500' by Saturday evening as a result of high pressure beginning to build over the area tomorrow and remaining through mid week. Meanwhile, although this area is experiencing a welcome relief from yesterday's lengthy rain event ("light snow showers are expected in extreme NE WA and the ID panhandle above 2500-3000'"), the bulk of the next "storm" is moving East by NE toward the Eastern Gulf, Queen Charlottes, the central coast of BC and Vancouver Island while the southern portion is approaching the coasts of WA and OR. Will it be strong enough to dislodge the ridge of high pressure mentioned above? The GFS and NAM models are currently suggesting that it will strengthen somewhat during the weekend and early next week. Mid afternoon weather for 10/24-not much change (a grey, gloomy overcast with a persistent light rain since earlier this morning), temperatures are in the low to mid 40's, BP 29.86"R along with slight air movement from the West. Current conditions for 10/25-mostly clear (widely scattered Cumulus), no precipitation during the overnight; however, there was heavy condensation on the gauge, the second snowfall is visible on the higher ridges and mountains around the valley, the haze is light with little to no air movement. It is from the West at 0-2 mph, wind puff: out of the West to 3 mph, humidity 76%, dew point 34°, current snow level is near 3500', observation time temperature was 31°, and the barometric pressure 30.10" and rising. |

So far, it has rained 0.12" since the observation time given above, and it is still raining! Yesterday, it was stated that this area was experiencing a welcome relief from the lengthy rain event-that occurred the day before-as both the GFS and NAM models showed high pressure building over the area by tomorrow (which would be today) and remaining through mid week. In the space of just 24 hours however, the NE side of this high pressure ridge "flattened" somewhat {due to an upper level low-South of the middle Aleutians-moving into the West side of this high pressure} thereby allowing a stream of clouds and energy to move East by SE over Vancouver Island, Southern and Southwestern BC, WA, Northern and Northeastern OR, most of the panhandle of ID and Western MT where one model at the time showed bands of scattered showers over and West of the Cascades as well as Eastern WA. Interestingly, these same models-mentioned above-show this ridge of high pressure re-establishing itself over the area (WA) tomorrow and remaining through mid week. In the meantime, the "National Weather Service in Spokane, has issued a winter storm warning for the East slopes of the Northern Cascades including Blewett and Loop Loop passes as well as the North Cascades highway West of Mazama where 3-7" of heavy snow is expected above 3000'". Current conditions for 10/26-a Nimbostratus overcast in the form of rain with little to no air movement. It is from the West at 1-2 mph, wind puff: out of the East to 6 mph, humidity was 88% [now 100%], dew point 38°, current snow level is near 4000', observation time temperatue 41°, and the barometric pressure 30.13" and rising. |

Yesterday, after 0.12" had been recorded by the observation time (8:00AM), an additional 0.19" was recorded by the time it stopped raining (5:45PM) for a grand total of 0.31"! The next system-is currently moving East by SE over the central coast, Southwestern and Southern BC, Vancouver Island, WA, and the Northern half of the ID panhandle. One model shows a very large band of rain moving East by SE over Western WA (most of the Olympic Peninsula and from Seattle to Vancouver with more intense precipitation in the Kent/Renton area and near the Tacoma to Centralia region) and NW OR, will be somewhat different than the previous one-where the rain came out of the Gulf of AK-as it is bringing a warm front with it. Another model shows it (the warm front) moving NE over SE Vancouver Island, NW to SE WA toward Southwestern and Southern BC. In the meantime, both the GFS and NAM models now show what appears to be a weak ridge of high pressure over WA that looks to remain through early next week before "flattening" to some degree by sometime tomorrow. Mid afternoon weather for 10/26-overcast (low Stratus and fog), temperatures are in the low to mid 40's, BP 29.98"F along with light air movement mainly from the SW, though occasionally from the SE. Current conditions for 10/27-overcast (low Stratus), the haze is light to moderate, 0.01" fell during the overnight, and very little to no air movement. It is from the WNW at 1-2 mph, wind puff: out of the NW to 4 mph, humidity 90%, dew point 38°, current freezing level is near 6000' {yesterday, it was near 4000'}, observation time temperature was 38°, and the barometric pressure 29.89" and falling. |

The total amount of rain recorded on 10/27 was 0.24", and most of the amount shown above occurred during the overnight. Last Saturday, it was mentioned that both the GFS and NM models showed high pressure building over WA before "flattening" somewhat by Sunday. It has, in fact, reestablished itself for today anyway, as it should once more "flatten" and rebuild sometime tomorrow and thus remain over the area (WA) through mid week. Meanwhile, the wet weather this area has been experiencing for the past few days will continue through most of the work week (where one model currently shows scattered showers over and West of the Cascades, the SE half of Vancouver Island with the largest band of scattered showers moving East by SE over Southern and Southeastern BC) as the arrival of the next system is expected over Western WA tomorrow; however, between now and then, "slight atmospheric drying should occur which can be seen on the water vapor loop". In the meantime, "precipitation will become showery over Eastern WA, with rain amounts today and tonight less than 0.25". But for Tuesday and Tuesday night, "another round of moderate to heavy rain will be possible with additional rain amounts between a half inch to an inch an a half". Current conditions for 10/29-much improved {mostly clear-scattered Cumulus) from earlier this morning (low clouds and fog), the haze is light with little to no air movement. It is from the West at 1-4 mph, wind puff: out of the West to 9 mph, humidity 72%, dew point 48°, current snow level is near 7500', observation time temperature 46°, and the barometric pressure 29.62" and falling. |

Although weak high pressure is over WA, a very impressive, comma-shaped upper level low-an indication of a "mature" storm-(centered off the NW coast of OR) is moving East by NE up the NW side of this high pressure and spreading rain over WA {where one model already shows a very large band of rain moving North by NE over Western WA-Tacoma to Vancouver-toward the Olympic Peninsula}, most of OR, and Northern CA. How will the upper level low affect this area? The "burn scars near Wenatchee are forecast to receive up to a half inch of precipitation today and less that a quarter inch by tonight and tomorrow". Looking ahead, the high pressure mentioned above, is projected to remain over the area one more day before moving East over the Northern Plains by sometime Thursday. Mid afternoon weather for 10/29-partly cloudy (scattered Cirrus, Cirrostratus, and Cumulus), temperatures are in the mid to upper 60's-which is about 12 to 15 degrees above normal for this time of year-, BP 29.72"F along with a nice breeze from several directions including the NW, North and West on an otherwise very pleasant autumn afternoon. Current conditions for 10/30-overcast and patchy fog, the haze is moderate with little to no air movement. It is from the West at 1-3 mph, wind puff: out of the ENE to 9 mph, humidity 89% (yesterday, the reading was 72%), dew point 47°, current snow level is near 8000', observation time temperature was 46°, and the barometric pressure 29.76" and rising. |

Yesterday, after 0.02" was recorded by observation time, an additional 0.09" was recorded as it rained intermittently all day and into the evening for a grand total of 0.11". Another upper level low-centered off the coast of WA-is moving East by NE (up the West side and cresting the ridge of high pressure over WA which should begin moving East over the Northern Plains sometime tomorrow) over Northern CA, NW NV, most of OR, the panhandle of ID, WA {where one model shows a very large band of rain moving North over NW OR and Western WA-Vancouver to the Olympic Peninsula-and the SE half of Vancouver Island} as well as Southern and Southeastern BC. Since the airflow is from the SW, it is believed therefore, that this low pressure system along with the previous one are in large part responsible for the mild conditions this area has experienced for the last few days and is reflected in part by a higher freezing level and above normal temperatures for this time of year. As for this area, "the burn scars left by the summer fires near Wenatchee, can expect additional rain amounts of a tenth to a quarter inch by Thursday". However, behind this upper level low, a cold front, currently moving East by SE toward WA and OR, should track East by NE over WA and Eastern OR by sometime
Thursday resulting in drier air and cooler temperatures for the next few days. Current conditions for 10/31-a gloomy, grey overcast (low clouds and fog that completely obscure the higher ridges and mountains around the valley), the haze is moderate along with little to no air movement. It is from the WNW at 0-1 mph, wind puff: is out of the NW to 6 mph, humidity 86%, dew point 51%, current snow level is near 8000', observation time temperature 50° (which is about 15 degrees above normal), and the barometric pressure 29.63" and rising. |

Yesterday, a cold front tracked East by NE over WA and NE OR and effectively lowered the maximum freezing level a few thousand feet from 8000' (the past two days) to a lower maximum of 6000'-7500' for today and tomorrow which should result in drier conditions for the period just mentioned. In the meantime, another wave, currently well off the West Coast, should make landfall by sometime Saturday. Mid afternoon weather for 10/31-overcast (low clouds and fog-although it has somewhat lifted), temperatures are in the low to mid 50's, BP 29.51"F along with calm winds. Current conditions for 11/01-mostly overcast with patchy fog, no precipitation in the the last 24, although there was heavy condensation on the gauge, the haze is moderate with little to no air movement. It is from the South at 0-2 mph, wind puff: out of the SSE to 8 mph, humidity 82%, dew point 46°, current snow level is near 6000' [yesterday, it was near 8000'], observation time temperature was 46°, and the barometric pressure 29.61" and falling. Here are some interesting stats for OCTOBER- 1) total rain: 1.87" OR, 382% of average, 2) number of days with no precipitation: 21, 3) high BP: 30.22" on 10/03, 4) low BP: 29.38" on 10/16, 5) date with low BP and no precipitation: 29.59" on 10/12, 6) date with high BP and precipitation: 30.13" on 10/26 (0.31"), 7) average BP: 29.83", 8) average morning temperature: a) official minimum: 40.1°, b) normal average low: 38.2°, 9) low morning temperature: a) official minimum: 27° on 10/21, 10) high morning temperature: a) official maximum: 60°, on 10/02, 11) average afternoon temperature: a) official maximum: 62.9°, b) normal average high: 62.4°, 12) low afternoon temperature: a) official minimum: 43° on 10/22 & 10/24, and 13) high afternoon temperature: a) official maximum: 78° on 10/01. |

The northern half of clouds and energy are moving NE by West over central and Southwestern BC, Vancouver Island, SE AK, and the Northern Gulf in response to the counterclockwise rotation of an upper level low-centered SE of Kodiak Island-and is also exerting influence on a very large pool of colder, drier air immediately to the South of it while the southern half is moving East by NE over Western WA, extreme Western OR, and Northern CA. Meanwhile, the maximum freezing level should hover between 6500'-7500' today and tomorrow before rising to 10,000' by Sunday and remaining high (8500'-9500') through early next week when it is projected to reach a minimum level 2500' near the end of the work week as there are indications that by early next week a cold front will track SE over WA followed by another one near mid week; however, this one should track South by SE over WA, Western OR and NW CA. Mid afternoon weather for 11/01-mostly cloudy (scattered Cirrus, Cirrostratus, Cumulus, and a large sheet of Altocumulus), temperatures are in the upper 50's to low 60's, BP 29.70"R along with light air movement, mainly from the West and South, though occasionally from the East. Current conditions for 11/02-partly cloudy with patchy fog, no precipitation in the last 24, the haze is light with little to no air movement. It is from the West at 1-2 mph, wind puff: out of the NNW to 9 mph, humidity 78%, dew point 44°, the freezing level is near 6500', observation time temperature was 38°, and the barometric pressure 29.89" and rising. |

The relatively large pool of cold air associated with an upper level low -which is still centered South of Kodiak Island-will be prevented from affecting the area (WA) for the time being as the NPJ, GFS, and NAM models all show the upper level winds generally in a SW flow over WA resulting in mild temperatures and a higher than average maximum freezing level for this time of year. High pressure should establish itself over WA sometime tomorrow (Sunday-believe it or not, the maximum freezing level will be near 10,500'!) and by the following day-Monday-the air flow over WA should be, once again, from the SW. However, there are indications that by early next week, a cold front will track SE over WA followed by another one near mid week which should track South by SE over WA, Western OR, and NW CA and bring with it much colder air to the area. In the meantime, clouds and energy are currently moving East over Vancouver Island, Southwestern, Southern and Southeastern BC (one map shows low pressure over the Canadian Rockies and the likelihood of snow, while another model is showing a band of rain moving NE over the SE tip of Vancouver Island and Vancouver), WA, and most of OR {except for the SW portion}. Mid afternoon weather for 11/02-overcast (some low clouds and patchy fog), temperatures are in the upper 40's, BP 29.89"R along with light air movement from the South. Current conditions for 11/03-overcast (scattered Cirrus, Cirrostratus, and Altocumulus), no precipitation since earlier this morning, the haze is moderate with little to no wind. It is first from the North at 2 mph, then from the East at 0-4 mph, and finally from the South at 12 mph, wind gust: out of the North to 4 mph, then out of the SSE to 16 mph, humidity 84%, dew point 49°, current snow level is near 7500' [yesterday, it was near 6500'], observation time temperature was 44°, and the barometric pressure 29.87" and rising. |

High pressure has established itself over WA today (although it is mostly cloudy to overcast) and by tomorrow, the air flow over the state should again be from the SW resulting in continued mild temperatures and an above average maximum freezing level for this time of year. A case in point-the maximum freezing level will range between 9500'-11,000' today through tomorrow night. But big changes appear to be on the way. For tomorrow, one model shows a cold front moving East by SE over the Western interior and Southwestern BC, the SE half of Vancouver Island toward NW WA (Olympic Peninsula). Later the same day, this same cold front is shown tracking East by SE over the Eastern third of WA and NW OR but now with a low pressure over NE WA, and high pressure off the WA/OR coasts. However {looking ahead to near the end of the work week}, with high pressure over the SE portion of the Yukon, and NE Alberta, along with a cold front tracking South by SW over Southern and South western MT and NW to SE WA, sets up the likelihood of much colder air spreading over a large area of WA through the weekend. As a result, the area should expect "cold overnight temperatures (upper teens to low 20's), gusty winds, and the possibility of SNOW". Mid afternoon weather for 11/03-mostly overcast (scattered Cirrus,Cirrostratus, and Altocumulus), temperatures are in the low to mid 50's, BP 29.85"R along with calm winds. Current conditions for 11/04-mostly cloudy (scattered Cirrus, Cirrostratus, Altocumulus, Altostratus and widely scattered Cumulus), no precipitation in the last 24, the haze is light with little to no air movement. It is from the North at 1-2 mph, wind gust: out of the NNW to 12 mph, humidity 80%, dew point 48°, current snow level is near 9500' [ yesterday, it was near 7500'], observation time temperature was 49° (which is 16° above average for this time of year!), and the barometric pressure 30.04" and rising. |

"Stubborn" high pressure should remain over WA today and tomorrow {resulting in continued mild temperatures and an above average maximum freezing level for the period mentioned above. As a case in point, the current freezing level is near 10,500', rising to near 12,000' by tonight then lowering to a minimum level of 9000' tomorrow afternoon} before shifting East over the Northern Plains. With this "shift", the door will likely be open for big changes due to "a cooler and unsettled weather pattern moving into the region"-spreading much colder air over WA through the weekend-"Thursday into Friday. Snow levels will be falling to valley floors with the potential for cold overnight temperatures (upper teens to low 20's), gusty winds, and light snow showers". Mid afternoon weather for 11/04-mostly cloudy (mainly scattered Cirrus, Cirrostratus, and widely scattered Cumulus), temperatures are in the low to mid 60's, BP 30.14"R along with light air movement from the South. Current conditions for 11/05-mostly cloudy (scattered Cirrus, Cirrostratus, Altocumulus, and small areas of Altocumulus Undulatus), no precipitation in the last 24 although there was heavy condensation on the gauge earlier this morning, the haze is light with some light air movement though it has picked up in the last hour. It was first from the East at 4 mph, then from the North at 4-6 mph, and finally from the WNW at 4-6 mph, wind gust: out of the NNW to 8 mph, then from the NW at 12 mph, humidity 64% (yesterday, the reading was 80%, dew point 44°, current freezing level is near 10,500' [ yesterday, it was near 7500'], observation time temperature 42°, and the barometric pressure 29.97" and rising. |

It appears that the combination of high pressure or a SW flow over the area for the past ten days along with the resultant mild temperatures, is finally coming to an end. For the time being however, clouds and energy are moving East by NE over Vancouver Island and Southern BC {where one model shows a lengthy band of precipitation moving NE and extending SW to NE over SE Vancouver Island-along with areas of more intense rainfall-to Revelstoke-with more intense precipitation NE of Meritt and West of Vernon) with some of this energy moving East over Western Alberta and South over the Northeastern boundary counties of WA. However, behind the energy and clouds, major changes are on the way as much colder air should begin to spread over WA by sometime tomorrow due in part (to the arrival of the first of two cold fronts. This first one is shown moving East by SE over the middle third of WA and Northern-East of The Dalles area-to South western OR) and "a cooler and unsettled weather pattern moving into the region Thursday and Friday" as a second cold front should arrive by sometime Thursday bringing even colder air to the region through the weekend. "Snow levels should be falling to valley floors with the potential for cold overnight temperatures (upper teens to low 20's), gusty winds, and light snow showers". Mid afternoon weather for 11/05-mostly overcast (Cirrostratus and Altocumulus), temperatures are in the upper 50's to low 60's, BP 30.05"R along with light air movement from the NW. Current conditions for 11/06-mostly cloudy (Cirrus, Cirrostratus, an immense halo, and Cumulus to the NW), no precipitation in the last 24, the haze is light to moderate with little to no air movement. It is from the North at 1-3 mph, wind gust: out of the NNW to 10 mph, humidity 70%, dew point 36°, current snow level is near 10,000', observation time temperature was 35°, and the barometric pressure 29.95" and rising.

The amount shown above was recorded after yesterday's observation time at the time indicated below. This observer stands corrected somewhat as one model (ECMWF) shows a ridge of high pressure over the area (WA) and an upper level low over the Gulf-West of SE AK. From this point, the upper level low is projected to track SE over the Southern half of SE AK, the Queen Charlottes, and the NW half of of Vancouver Island by tomorrow and arrive over Southern BC, most of WA, OR and NW CA by the end of the work week. At the same time, a combination of the upper level low-mentioned above- with another cold front (shown moving South by SW over SW MT to the Northern panhandle of ID, NE WA and its northern border, as well as the NE coast of Vancouver Island) is expected to bring even colder air to the region through the weekend. In the meantime, one weather map shows low pressure over SE BC and a cold front {in addition to some clouds and energy ahead of it moving SE though dissipating in the process as "they" attempt to move up the NW side of a high pressure ridge now over the Northern Plains} tracking East by SE over NW MT, the central panhandle of ID, SE OR, and NW CA. With it's passage over WA yesterday, the air behind it is cold enough for snow down to pass level in the Northern and central Cascades of WA. Current conditions for 11/07-partly cloudy (scattered Cumulus), no precipitation during the overnight, the haze is light along with some light air movement. It is first from the West at 3 mph, then from the South at 3-4 mph, wind gust: out of the WSW to 20 mph, then from the South to 6 mph, humidity 56%, dew point 26° {yesterday, the readings were 70% and 36° respectively}, current snow level is near 3000' [yesterday, it was near 10,000'], observation time temperature was 36°, and the barometric pressure 29.83" and rising. |

Yesterday, it was mentioned that behind the clouds and energy {tracking East by NE over Vancouver Island and Southern BC with some of this energy moving East over Western Alberta, and South over the Northeastern boundary counties of WA} major changes were on the way as much cooler air was to begin spreading over WA by sometime tomorrow-11/07-(which would now be yesterday-and it did as the maximum temperature in this area, anyway, began to decline in the early afternoon as a result of cooler air movement mainly from the North and NW) with the arrival of the first cold front. A second cold front in combination with a "cooler unsettled weather pattern" should arrive over the area (though there is "not a whole lot of moisture with it because it is coming out of the Gulf of AK and as a result will provide more cold air than wet weather") by sometime today or tomorrow and bring even colder air to the region through the weekend. Snow levels will be falling to valley floors with the potential for cold overnight temperatures-low to mid 20's-(although most of this action will occur over NE WA, the Spokane area and the WA Palouse where 1-3" are expected.) Mid afternoon weather for 11/07-partly cloudy (scattered Cumulus), temperatures are in the low to mid 50's, BP 29.86"R along with light air movement mainly from two directions-the North and NW. Current conditions for 11/08-mostly clear (widely scattered Cumulus and Altocumulus which is quite a contrast from earlier this morning when it was overcast with light sprinkles), the haze is light to moderate with little to no air movement. It is from the West at 2-8 mph, wind gust: out of the WNW to 10 mph, humidity 54%, dew point 33°, current snow level is near 3000', observation time temperature was 35°, and the barometric pressure 29.75" and falling. |

Even though high pressure is over the Northern Great Plains, the upper level trough has deepened considerably since yesterday and extends well beyond WA and OR with its Southernmost boundary now over Northern Baja, CA. But, as was mentioned yesterday, "there's not a whole lot of moisture with it because it is coming out of the Gulf of AK, and as a result, will provide more cold air than wet weather". Other than a light dusting of snow on Badger Mountain earlier this morning, the weather here has been rather "quiet". East of this area (WA) however, the worst weather will be found in MT in the form of "a major winter storm moving into ID, MT and ND bringing with it heavy snow and blizzard conditions" from Great Falls, MT to the Williston area of ND and the Theodore Roosevelt Nat'l Park-both units-where 12-17" are expected through tomorrow due to a strengthening-though slow moving-winter storm (currently centered off the SW OR coast; however, it is expected to continue tracking NE and arrive
SW of the Spokane area later today along with a cold front moving West by SW over NW to South central WA) "interacting with an Arctic high pressure over Northern Canada". Mid afternoon weather for 11/08-partly cloudy (Cirrostratus, scattered Altocumulus and Cumulus), temperatures are in the upper 40's to low 50's, BP 29.59"F along with light air movement from the NW. Current conditions for 11/09-mostly cloudy (Cumulus), the haze is light to moderate with light air movement. It is from the WNW at 0-2 mph, wind puff: out of the NW to 5 mph, humidity 67% {yesterday, the reading was 54%}, dew point 33°, current snow level is near 2000' [yesterday, it was near 3000'], observation time temperature 33°, and the barometric pressure 29.67" and falling. |

The very deep trough off the West coast the past few days, finally began to move inland over NW OR and CA today with its Southernmost boundary over the northern half of Baja, CA and the corresponding low pressure now centered over SE BC. However, immediately behind this upper level trough a narrow ridge of high pressure off the West coast will give way to another system moving East by NE over SE AK, the Queen Charlottes and toward the coasts of central BC, Vancouver Island, WA, OR, and is expected to arrive over the area (WA) sometime tomorrow. However, the worst weather continues to be East of the area (WA) as one weather map shows low pressure off the NW coast of OR, and the likelihood of moderate to heavy snow in NE MT, most of ND (where 10-15" are expected) and NW SD as a result of three weather "ingredients" interacting with each other. "A cold front (first ingredient) is draped from the central Plains to the SW with low pressure (second ingredient) in the central Plains along the front, enhancing the snow to its North in the Dakotas. A strong high pressure (third ingredient) in North central Canada, is drawing in bitterly cold air and the pressure difference between the high and low is generating northeast winds across the Northern Tier". Current conditions for 11/10-partly cloudy (scattered Altocumulus and Cumulus), light to moderate haze with little to no air movement. It is from the East at 0-3 mph, then from the South at 0 mph, wind puff: 34°, and the barometric pressure 29.85" and rising. |

The narrow ridge of high pressure that yesterday was off the West coast, has moved over the area (WA) today and for most of tomorrow (though weakening in the process) as one front is moving East across WA (where one model is showing a large band of scattered showers moving East by NE over the Olympic Peninsula, Western WA, and NW OR) followed by a smaller "disturbance"-immediately to the SW-moving East by NE toward the the coasts of WA and NW OR. With cold air near the surface in Eastern WA, "a winter weather advisory has been posted for this area-as well as others-where 2-4" are expected to fall during the overnight and early morning hours. However, this snow will be short lived as a warm front is shown tracking North by NE over SE to NW WA and as a result, the maximum freezing level should rise from its current level of 1000' to near 5000' by sometime tomorrow. Mid afternoon weather for 11/10-partly cloudy (scattered Altocumulus and Cumulus), temperatures are in the upper 30's to low 40's, BP 29.97"R along with light air movement from the SE. Current conditions for 11/11-overcast (Altostratus, scattered Cumulus and low clouds), no precipitation in the past 24, the haze is moderate with little to no air movement. It is from the West at 1-2 mph, then from East at 2-3 mph, wind puff: out of the ENE to 5 mph, humidity 68%, dew point 26°, current snow level is 1000' rising to 2500' later this afternoon, observation time temperature was 25°, and the barometric pressure 30.11" and rising. |

Weak high pressure should remain over the area (WA) today before weakening considerably by tomorrow. In the meantime, most of the rain has moved South over NW OR where one model is showing a band of rain moving East by NE over Western OR (East of Albany/Corvallis, and NW of Bend) while a relatively large band of snow is also tracking East by NE over SE WA (from East of Moses Lake to Pullman, and Northward to Spokane) along with rain on its SW side over Walla Walla and Pendleton OR. Mid afternoon weather for 11/11-overcast (Cirrostratus, Altocumulus, scattered Cumulus and low clouds), temperatures are in the mid to upper 30's, BP 30.15"F along with light air movement from the NE though occasionally from the SW. Current conditions for 11/12-mostly cloudy (scattered Cirrus, Cirrostratus, Cumulus and low clouds), the haze is light to moderate with little to no air movement. It is from the West at 0-2 mph, wind puff: out of the WNW to 3 mph, humidity 93%, dew point 33° {yesterday, the readings were 68% and 26° respectively}, current snow level is near 4500' [yesterday, it was near 2500'], observation time temperature was 31°, and the barometric pressure 30.08" and rising. |

"Upper level energy and onshore flow will produce rain along the PNW coast and portions of Northern CA" as clouds-associated with a disturbance-are currently tracking SW to NE before turning East by NE over Southern WA, OR, Northern CA and bringing scattered showers (some of which have more intense precipitation embedded within them) over most of Western WA (Tacoma/Olympia area, Olympic Peninsula, and the SE tip of Vancouver Island). With the passage of this disturbance (mentioned above), the next several days should be void of precipitation as there is not much by way of "active weather" behind this disturbance other than a relatively large upper level trough well off the West coast followed by high pressure over most of the Gulf region. Mid afternoon weather for 11/12-mostly clear (widely scattered Cirrus, Altocumulus, Cumulus, and low clouds), temperatures are in the the upper 30's to low 40's, BP 30.06"R along with light air movement from the SW. Current conditions for 11/13-a low Stratus overcast, no precipitation in the last 24, the haze is light to moderate with little to no air movement. It is from the East at 0 mph, wind puff: out of the East to 3 mph, humidity 92%, dew point 33°, current snow level is near 4000', {which caused yesterday's snow accumulations-in the lower elevations-to melt as a result}, observation time temperature was 35°, and the barometric pressure 30.13" and rising. |

Even though the PNW will continue to remain unsettled as more wet weather is headed this way, high pressure is currently circulating over the Eastern Pacific off the WA coast. However, lurking behind it is a front which extends all the way to the Gulf-along with a cold front-and "will remain there a few days for a push from an area of low pressure in the Gulf" at which time "this front is projected to move through/over WA and dramatically change the weather by the weekend" through early next week with rain, snow and breezy conditions. Mid afternoon weather for 11/13-little if any change from earlier in the day (overcast-low clouds), temperatures are in the upper 30's to low 40's, BP 30.05"R along with slight air movement from the NW and East. Current conditions for 11/14-another overcast and low clouds morning, no precipitation in the last 24, the haze is moderate to bad with little to no air movement. It is from the West at 7 mph, wind puff: out of the West to 7 mph, {yesterday, it was out of the East to 3 mph!}, humidity 87%, dew point 34°, current snow level is near 4000', observation time temperature was 36°, and the barometric pressure 30.06" and rising. |

High pressure centered over the central panhandle of ID, will provide one more day of "tranquility" as a more stormy weather pattern-in the form of rain and wind-is on the way with the first in a series of systems expected to arrive over the area (WA) by the end of the work week and remain through the first part of the weekend. This should be followed by a second and more potent system early next week that should affect WA, OR, and Northern CA with more rain, wind and heavy snow above 5500-6000'. Looking ahead to the weekend, there are indications of a cold front passing over the area (WA) by sometime Sunday. Mid afternoon weather for 11/14-much the same as yesterday and this morning-little if any change in the low cloud overcast. Temperatures are in the upper 30's to low 40's, BP 30.19"R along with light air movement mainly from the East and SE, but occasionally from several other directions including the North, South, and SW. Current conditions for 11/15-a continued low cloud overcast-although a light drizzle has begun-, the haze is moderate with little to no air movement. It is from the East at 0-2 mph, wind puff: is out of the East to 6 mph, humidity 83%, dew point 33°, current snow level is near 5500' [yesterday, it was near 4000'], observation time temperature was 36°, and the barometric pressure 30.15" and rising. |

A storm that yesterday was centered off the coast of Southern CA and spread clouds and energy over Northern CA, has since moved North by NE over OR, WA (where one model shows a lengthy band of scattered showers moving SW to NE over NW OR, SW to Western WA (from Centralia to Eatonville toward I-90) and the panhandle of ID. In the meantime, "an active weather pattern will develop Saturday and likely continue through Thanksgiving day" with the first one-in a series of potent systems- arriving over Western WA by sometime tomorrow bringing with it "periods of heavy rain-especially to the coast and Olympic Peninsula, breezy or windy conditions, and snow-with the highest passes, Paradise and Mt. Baker" receiving the heaviest snowfall. Mid afternoon weather for 11/15-little if any change in the low Stratus overcast from earlier this morning, although there was a brief period of misty drizzle. Temperatures are in the upper 30's to low 40's, BP 29.97"F along with calm winds. Current conditions for 11/16-the low Stratus overcast continues, no precipitation in the last 24, the haze is moderate with little to no air movement. It is from the North at 2-5 mph, wind puff: out of the NNW to 8 mph, (yesterday, it was out of the East to 6 mph!), humidity 85%, dew point 35°, current snow level is near 4500' [yesterday, it was near 5500'], observation time temperature was 37°, and the barometric pressure 29.83" and falling. |

By observation time, 0.01" had already been recorded; however, since that time, an additional 0.11 was recorded for a total of 0.12" (and it's still raining!). The next in a series of potent storms is shown centered South of the Queen Charlottes along with a cold front tracking East by NE toward the coasts of Southern Queen Charlottes, central coast of BC, Vancouver Island, WA, OR, and Northern CA with the precipitation ahead of it in the form of rain for the time being as the air flow over the regions just mentioned is from the SW. As the current system impacts WA, it will bring rain-("to the coast and interior lowlands-0.25"to 1.25"-tonight through tomorrow" along with "heavier amounts Sunday night through Monday where 3" on the coast and 2" in the interior lowlands are expected"), snow-("to the mountains tonight through tomorrow and tomorrow night where a total of 5-15" are expected) and wind-("breezy or windy conditions-which is likely with the arrival of successive fronts"). This should be followed by a brief drying period (due to cooler, drier air as an upper level trough moves inland over WA and Western OR) before the arrival of the next potent storm by sometime tomorrow. Current conditions for 11/17-A Nimbostratus overcast in the form of rain with little to no air movement. It is from the East at 0 mph, wind puff: out of the ESE to 4 mph, humidity 100%, dew point 39°, current snow level is near 5500' [yesterday, it was near 4500'], observation time temperature was 39°, and the barometric pressure 29.65" and falling. |

Yesterday, it continued to rain after 0.12" was recorded and an additional 0.11" was recorded for a grand total of 0.23". With the passage of yesterday's potent storm, a drying period ensued this morning as a result of an upper level trough moving over WA and Western OR that brought cooler, drier air to the area. The northern half of a cold front-associated with low pressure (currently centered SW of and tracking NE toward the Queen Charlottes) is moving East by NE and nearing the Southern tip of the Queen Charlottes, the coasts of central BC, Vancouver Island, and WA, while the southern half is tracking East by SE and approaching the coasts of OR and NW CA pushing precipitation ahead of it-in the form of rain-over Vancouver Island, SW BC, Western WA and CA. In the meantime, "a series of wet Pacific frontal systems will move through Western WA in quick succession" with the first of these arriving over Western WA by sometime this evening spreading snow to pass levels tonight and tomorrow where total snow accumulations are expected to range from 9-28" (which includes today's total). By way of contrast, rain is in the forecast for this area tomorrow-where up to 0.75" is possible- and tomorrow night, snow above 3000' (1-3" are expected), and wind. Mid afternoon weather for 11/17-a very grey, gloomy Stratus overcast. Temperatures are in the upper 30's to low 40's, BP 29.44"F along with slight air movement from the NW. Current conditions for 11/18-partly sunny (scattered Cirrus, Cirrostratus and Cumulus), the haze is moderate with little to no air movement. It is from the East at 0-1 mph, wind puff: out of the East to 7 mph, humidity 77%, dew point 34° {yesterday, the readings were 92% and 39° respectively}, current snow level is near 3000' [yesterday, it was near 5500'], observation time temperature was 31°, and the barometric pressure 29.70" and rising. |

The amount recorded above is a result of intermittent showers from last evening to the present time. One model shows clouds and energy containing copious amounts of moisture extending SW to NE (though moving in a general NE direction) over Northern CA, OR, WA {where one model is showing a very large band of rain moving NE from NW OR to SE Vancouver Island with numerous areas of more intense precipitation embedded in this band especially from Everett to Victoria, BC}, the northern panhandle of ID and NW MT as "the Northwest continues to get pounded with a parade of storms bringing rain, snow and gusty winds". It is believed therefore, that the combination of the clouds and energy-mentioned above-with the NPJ is responsible for the heavy moisture over Western WA today. Current conditions for 11/19-overcast and somewhat threatening in appearance toward the South and SE, the haze is light to moderate with little to no air movement. It is from the East at 3-5 mph, wind gust: out of the East to 25 mph, humidity 83%, dew point 41°, current snow level is near 5000' but 3000' in the passes, observation time temperature was 41° [or 10° above yesterday's reading], barometric pressure 29.51" and falling. |

Earlier today, it was stated that a low pressure system off the NW coast of Vancouver Island was poised to move over Western WA by sometime this evening; however, it is believed that this will not be the case as several models-including the ECMWF, Canadian, GFS and NAM-reveal no low pressure in that locale. In the meantime, another model shows a system-"extending back toward HI"-tracking NE toward OR and is expected to arrive over Eastern WA by sometime this evening with widespread moisture in the form of rain to the lower elevations as "warm air surges ahead of it (the low pressure system) while the higher elevations should experience heavy snow fall". After looking at other models, there are indications that most of the moisture associated with this latest system will be headed South of WA into OR and Northern CA. Mid afternoon weather for 12/02-except for some ominous clouds near the NW, West and SW horizon, the sky is mostly clear (scattered Cirrus and Cumulus-the dominant variety). Temperatures are in the upper 40's low 50's, BP 29.36"R along with air movement from the West. Current conditions for 12/03-partly sunny (scattered Cirrus, Cirrostratus, Altocumulus and Cumulus), a light frost was observed earlier this morning, the haze is light with little to no air movement. It is from the East at 7-10 mph, wind gust: out of the East to 17 mph, humidity 76%, dew point 36°, current snow level is near 3500', observation time temperature was 31°, and the barometric pressure 29.71" and rising. |

While one model currently shows scattered showers moving NE over NW OR, SW WA to the passes (East of Seattle), the Western and NW sides of the Olympic Peninsula, SE Vancouver Island, and NW WA (Bellingham area), a winter storm warning has been posted for the higher elevations of the Northern and Southern Cascades where "12-18" and 6-12" respectively are expected as a result of an "up slope flow". As for this area, a total snow accumulation of 8-16" is expected on Snoqualmie and Stevens passes by tomorrow. Looking ahead, it appears that a much cooler/colder pattern is in the making beginning tomorrow and lasting through the weekend as high pressure-now building West of the WA/OR coasts-replaces the low pressure of the past several days that brought abundant precipitation to Western WA. This should open the door for cold, dry arctic air to invade most of WA, NW OR, and Western MT resulting in lower snow levels and each successive day (starting with tomorrow) is projected to be cooler/colder than the previous one through this weekend. Current conditions for 12/04-overcast (low Stratus and fog) with intermittent showers and little to no air movement. It is from the East at 1-2 mph, wind gust: out of the East to 21 mph, humidity 86% (yesterday, the reading was 76%), dew point 39°, current snow level is 6000' lowering to 5000' later this afternoon, observation time temperature was 39°, and the barometric pressure 29.51" and falling. |

The amount shown above was in the form of intermittent showers late last evening and early this morning. Although the current flow pattern over WA is zonal, as of last evening, the low pressure over the Gulf region is finally beginning to show signs of "breaking loose" as it first tracks NW toward the Kenai Peninsula and Kodiak Island before beginning a lengthy SE journey from SE AK to West TX before turning NE and finally ending up over MO. This should result in more normal December conditions. In the meantime, another low pressure is moving across the Pacific-as a result of a "very active jet stream"-and should arrive over the vicinity of SE Vancouver Island and NW WA (Olympic Peninsula) by sometime today into tomorrow. This will be followed by yet another low pressure arriving over the area (Western WA) by sometime tomorrow into Friday. As mentioned yesterday, a much cooler pattern was in the making as high pressure-now West of the WA/OR coasts will gradually replace the two low pressure systems (mentioned above). As a result, this action should open the door for arctic air to invade most of WA later in the week (the air flow pattern over WA at this time should be from the NW) with the coldest period likely to be Saturday as one model shows a strong cold front tracking East by SE and is expected to arrive over Western WA by sometime Saturday. Current conditions for 12/05-mostly sunny (scattered Cumulus-the dominant variety-and widely scattered Cirrus), no precipitation during the overnight, the haze is light with little to no air movement. It is from the West at 2-3 mph, wind gust: out of the WNW to 15 mph, humidity 64%, dew point 22° {yesterday, the readings were 86% and 39° respectively}, current snow level is near 2000' [ yesterday, it was near 5000'], observation time temperature was 37°, and the barometric pressure 29.76" and rising. |

Yesterday's low pressure system that was tracking across the Pacific-as a result of "a very active jet stream"-finally moved inland over most of WA, OR, ID, and Western MT today. This will be quickly followed by yet another system; however, at this time, it appears that the bulk of it will be heading south of WA into OR and Northern CA. It was also mentioned yesterday, that the low pressure over the Gulf region was showing signs of "breaking loose" and that it would track NW toward the Kenai Peninsula and Kodiak Island-which indeed it has done-then turn SE over SE AK with the center just off the coast. According to the Canadian model, this locale should be the end of the line for the low pressure system (mentioned above)-as far as its projected lengthy SE journey was concerned due to a strong ridge of high pressure building over the Gulf region. Looking ahead, a much "cooler and drier" pattern is still in the making with the coldest period likely to be Saturday followed by a chance for an inversion the next day as high pressure will be firmly established over the area (WA). Mid afternoon weather for 12/05-partly cloudy (scattered Cirrus, Altocumulus, and Cumulus). Temperatures are in the upper 40's to low 50's {which is 7-10 degrees above normal for this time of year}, BP 29.96"R along with air movement mainly from the NW but occasionally from the SW. Current conditions for 12/06-a thick Altostratus overcast with snow falling on or near Mission Ridge to the SW, no precipitation in the past 24, the haze is moderate with little to no air movement. It is from the North at 0-1 mph, wind gust: out of the NNW to 14 mph, humidity 78%, dew point 29° (yesterday, the readings were 64% and 22° respectively), current snow level is near 2000', observation time temperature was 27°, and the barometric pressure 29.94" and rising.

Although the current system is bringing "lowland showers to Western WA, and heavy snow in the mountains"-as one model shows heavy snow for SW BC and the WA Cascades-e.g. "an additional 10-20" of new snow is expected through tonight" on Snoqualmie and Stevens Passes. "This will be on top of the 1-2' that has already fallen in the last day and a half". The agent responsible for this active weather continues to be a very active jet stream currently directing moisture over WA (in addition to a low pressure centered just West of SE AK-according to both the Canadian and ECMWF models) and OR. Immediately behind this system, another one (NW of HI and extending SW to NE-toward the Gulf) is being deflected toward the Gulf region and SE AK as a ridge of high pressure is building near the Gulf region off the WA/OR coasts and should effectively terminate the wet weather of the past few weeks over WA. This should result in a drier and cooler pattern through the weekend with the coldest period likely to be Saturday. In addition, there is a chance for an inversion by Sunday as high pressure will be firmly established over the area trapping cooler air near the surface. Current conditions for 12/06-overcast (Altostratus), cool and breezy as it is snowing on the higher ridges and mountains around the valley except Badger mountain to the East. The haze is light to moderate along with light air movement. It is from the WNW at 0-4 mph, wind gust: is out of the NW to 17 mph, humidity 70%, dew point 34°, current snow level is near 2500', observation time temperature was 32°, and the barometric pressure 29.81" and rising. |

Yesterday at observation time (7:40A), a trace had been recorded. Afterward, this was followed by intermittent light showers and 0.01" was recorded. However, in the time indicated below, an additional 0.04" was recorded for a grand total of 0.05". Although the clouds over most of WA appear to be separate from a much larger system (centered South of the middle Aleutians) that extends East over SW AK, the Gulf region, the Queen Charlottes, extreme Western BC and most of Vancouver Island, they should dissipate as the day progresses due to a ridge of high pressure-which, at this time, appears to have strengthened since yesterday (according to the Canadian model)-establishing itself over the Gulf region and sets up a NW flow over WA and OR that should result in a drier and cooler pattern through the weekend. In addition, one model shows a cold front tracking South by SW over SE BC, central and NW MT toward ID and WA with a possibility of snow in Northern to Southeastern OR and ID. Mid afternoon weather for 12/07-a mostly overcast and raw late autumn afternoon. Snow continues to fall on the higher ridges and mountains around the valley along with a dusting on some of the lower foothills. Temperatures are in the low to mid 40's, BP 29.70"F with light air movement from the NW. Current conditions for 12/08-mostly cloudy (scattered Cirrus, Cirrostratus, Altocumulus and patchy fog), no precipitation during the overnight, the haze is light along with little to no air movement. It is from the WNW at 2-5 mph, wind gust: out of the NW to 14 mph, humidity 64%, dew point 32°, current snow level is near 1000' [ yesterday, it was near 2500'], observation time temperature was 33°, and the barometric pressure 29.96" and rising.

At the present time, the jet stream is well to the North as strong high pressure-both at the surface and aloft-is centered off the coast of Northern CA. Several models show clouds and energy riding up and cresting this ridge (over the Gulf region before turning SE over SE AK, the Queen Charlottes, Vancouver Island, and the interior of South central BC) of high pressure. In the meantime, another system is developing over the Eastern Gulf and should arrive over WA by sometime tomorrow. In addition to a cold front tracking East by SE over NW (Olympic Peninsula) to SW WA, this next system should be stronger than yesterday's as it will bring "areas of heavy rain" to Western WA. With the passage of this system, there should be a break and then it appears that a couple of changes are in store. By mid-week, the current ridge of high pressure should give the area one more day of cooler and drier weather (lst change) before the jet stream pattern will undergo "big changes" by the end of the week. Instead of being in a NW flow over the area (WA)-as it currently is-it should be in more of a west to east pattern (or zonal) that will result in "windier and wetter" weather by the weekend (2nd change). Current conditions for 12/10-mostly clear (scattered Cirrus, Altocumulus, and widely scattered Cumulus), no precipitation in the past 24, a thin veneer of heavy frost was observed on both lawns as well as the gauge, the haze is moderate to bad with little to no air movement. It was from the East at 4-11 mph, wind gust: out of the ESE to 16 mph, humidity 81%, dew point 29°, current snow level is near 4500', observation time temperature was 26°, and the barometric pressure 30.12" and falling. |

The next system (with low pressure centered just West of SE Vancouver Island along with a cold front tracking East by SE over NW-Olympic Peninsula-to SW WA should move through the area later today) is not as strong as previously thought but does have more moisture than the last storm of a day or two ago. As a case in point, one model shows showers tracking East by NE over NW OR and at the same time approaching the southern coast of WA while a larger band-with more intense precipitation-moves over most of the Olympic Peninsula and the SE tip of Vancouver Island along with another band extending from NW WA (Bellingham area) to Vancouver, BC. This current wet weather will be followed by a drier day tomorrow which sets up the "rainy day/dry day" pattern "which should continue through the balance of the week" with the next system "forecast" to arrive by Thursday. Mid afternoon weather for 12/10-mostly sunny (scattered Cirrus, Cirrostratus, Altocumulus and Cumulus), temperatures are in the upper 30's to low 40's, BP 30.01"F along with air movement mainly from three directions including the NE, SE, and South. Current conditions for 12/11-partly sunny (scattered Altocumulus, Cumulus and patchy fog), no precipitation during the past 24, the haze is moderate to bad with little to no air movement. It is from the East at 0-3 mph, wind gust: out of the ESE to 11 mph, humidity 83%, dew point 31°, current snow level is near 3000' [yesterday, it was near 4500'], observation time temperature was 29°, and the barometric pressure 29.65" and falling. |

It is believed that the amount shown above was recorded last evening during the hours indicated below. Although this area is currently experiencing an overcast of low clouds and fog, today should be cooler and drier (due to low pressure over NW WA which should rotate this cooler and drier air over the area from off the Pacific by sometime today) than yesterday, as the storm that brought the precipitation {a rain/snow mix} has moved East over NE and SE WA, the central panhandle of ID, and most of MT. In the meantime, there has been "a little change in the weather pattern" as the ridge of high pressure-that has been "sitting" off the coasts of WA/OR for most of the week-has allowed a steady stream of weaker systems over the area (WA). However, by tomorrow, a stronger system should move in "by the weekend, the ridge of high pressure will weaken, the NPJ will more or less be in a zonal pattern over WA/OR" and, along with a low pressure centered off the coast of NW Vancouver Island, should result in stronger and wetter storms". Mid afternoon weather for 12/11-mostly cloudy with what appears to be scattered Altocumulus Duplicatus-the dominant variety-and Cumulus. Temperatures are in the upper 30's to low 40's, BP 29.45"F along with light air movement from the NW. Current conditions for 12/12-overcast (low clouds and fog though not on the deck), no precipitation during the overnight, the haze is moderate with little to no air movement. It is from the West at 2 mph, wind puff out of the West to 7 mph, humidity 84%, dew point 33°, current freezing level is near 2500', observation time temperature was 33°, and the barometric pressure 29.52" and falling.

With drier air extending North over most of CA before turning NE over SW to NE OR, Eastern WA, the Northern panhandle of ID, NW MT, and low pressure centered just West of SE Vancouver Island, the next system (along with a cold front-immediately behind it-that is tracking South by SE toward the coasts of central BC and the NW tip of Vancouver Island) is moving quickly and already spreading moister air from NW toward SE WA, while simultaneously tracking SE over the central coast and interior of BC and the NW half of Vancouver Island and should arrive near the coastal areas by sometime this afternoon thereby increasing the chance for rain. Following this "storm", tomorrow should be drier with a few sun breaks as high pressure should "set up" over NW WA (Bellingham) and extreme SW BC; which, looks to have the potential to rotate some cooler air over this area. By the weekend however, the "jet stream will shift south" of WA into Northern OR which will result in "guiding two systems" toward WA with the first one arriving over the area by sometime Saturday and the second (the strongest of the two-with "heavy rain and very strong wind") by the following day. Current conditions for 12/13-overcast and SNOWING! {no accumulation} with very little air movement. It is from the East at 4-8 mph, wind gust: also out of the East to 10 mph, humidity 86%, dew point 31°, current snow level is near 3000', the observation time temperatue was 32°, and the barometric pressure 29.88" and rising.

The system that brought light snow to this area during the overnight moved just East of this area over Eastern WA (where one model shows a band of light precipitation (rain) extending SW from the Tri cities into NE OR, and another larger band of light precipitation (possibly snow) "fanning out" from the Spokane area), Northern panhandle of ID, and NW MT that should result in a drier day for the time being. In the meantime, the jet stream will become more or less zonal over the area as high pressure over the Pacific {West of the OR coast} begins to simultaneously weaken and move South thereby opening the door to a couple of storms. The first one-which is centered off the tip of Vancouver Island-along with a cold front tracking East by SE over NW Vancouver Island, but toward the coasts of WA and OR- should arrive by sometime Saturday bringing "heavy rain along the coast which will spread Eastward during the morning into the afternoon along with heavy snow from Snoqualmie Pass North where 6" up to 12" are expected" respectively. The second storm is likely to arrive by sometime Sunday. Current conditions for 12/14-overcast (low clouds and fog-though not on the deck), the haze is moderate with little to no air movement. It is from the East at 1-2 mph, wind puff: out of the ESE to 5 mph, humidity 89%, dew point 31°, current snow level is near 2000' [yesterday, it was near 3000'], observation time temperature was 30°, and the barometric pressure 29.67" and falling. |

It would appear that there is a split in the jet stream with the northern half flowing into BC (where a small ridge of high pressure is currently situated) while the southern half turns SE in the form of a trough over Southern CA (including the Baja Peninsula). CAUTION: deteriorating conditions ahead for the weekend and early next week as the first in a series-of moderate strength-will bring light snow to the area (currently snowing!) today. This will be followed by a much stronger storm which should move in Sunday evening bringing heavy rain and gusty winds to Western WA as well as gusty winds and heavy snow to the areas mentioned below. As a result, the NWS posted a winter storm watch "from Sunday afternoon through Monday afternoon where 4-7" are expected for this area although communities on the East slopes of the Northern Cascades could receive as much as 6-12"
whereas for the mountains, 12-24" are possible". Mid afternoon weather for 12/14-continued overcast (low clouds and fog-though not on the deck), temperatures are in the upper 30's to low 40's, BP 29.70"F along with light air movement mainly from the West though occasionally from the East. Current conditions for 12/15-overcast and snowing! with very little air movement. It is from the East at 0-1 mph, wind puff: out of the East to 8 mph, humidity 88%, dew point 31°, current snow level is near 1000' [yesterday, it was near 2000'], observation time temperature was 30°, and the barometric pressure 29.75" and falling. |

Yesterday's two snow events resulted in a grand total of 0.08" as 0.03" was recorded from the first one-this was posted yesterday-and an additional 0.05" was recorded from the second. A much stronger system is winding up and heading toward WA bringing heavy rain and gusty winds to Western WA by sometime Sunday afternoon into Monday morning. For the mountains, 1-3" can be expected today along with another 1-3 FEET by late Monday. East of the Cascades, a "winter storm warning has been posted from late Sunday afternoon through Monday afternoon for this area where "4-7" are expected in addition to gusty winds". As for the "valleys/communities on the East slopes of the Northern Cascades, 7-11" are expected along with 8-12" in the mountains". Looking ahead, there are indications that additional strong storms could arrive over the area by mid week followed by another "on or about" the weekend. Mid afternoon weather for 12/15-currently it is overcast and snowing. Temperatures are in the low to mid 30's, BP 29.53"F along with calm winds. Current conditions for 12/16-partly sunny (scattered Cirrus, Altocumulus and Cumulus), no precipitation during the overnight, the haze is moderate along with minimal air movement. It is from the North at 0-1 mph, wind gust: out of the NNW to 12 mph, humidity 84%, dew point 26° (yesterday, the reading was 31°), current snow level is near 1000', observation time temperature was 23°, and the barometric pressure 29.57" and falling. |

After checking the state weather map and a weather model, it appears that from this area North to Chelan will be the only players not involved in "active" weather (strong winds, snow, or a combination of both). In the meantime, it was mentioned yesterday that there were indications of a strong storm arriving by mid week followed by another "on or about" the weekend. The first one looks to be more of a possibility and should be cooler than the storm of last evening as a "colder air mass settles over the area" and "high pressure slowly builds in from the West during the day Tuesday". This action should cause the "snow level to drop near sea level" before the arrival of the first storm. Mid afternoon weather for 12/16-overcast (low clouds and fog-though not on the deck), no precipitation as yet, temperatures are in the low to mid 30's, BP 29.44"F along with light air movement from the NE and occasionally from the NW. Current conditions for 12/17-mostly overcast, the haze is light along with light air movement. It is from the WNW at 4-10 mph, wind gust: out of the NW to 28 mph, humidity 74%, dew point 30° {yesterday, the readings were 84% and 26° respectively}, current snow level 2500' lowering to 1000' later this afternoon, observation time temperature was 32°, and the barometric pressure 28.97"and falling (This is the lowest BP of record since I began observing in 2009. The previous record of 29.04" occurred on 12/02/12). |

Although this area is currently experiencing a beautiful tranquil day, tomorrow should present an entirely different "picture". On Sunday, it was first mentioned that there were indications of another strong storm arriving over the area by mid week along with signs that this storm would be cooler/colder than the the previous one (Sunday into Monday) as a "colder air mass settles over the area" (Western WA). This action is believed to be the result of a cold front-over the Pacific-tracking SE toward WA/OR and pushing ahead of it a portion of a larger "bubble" of cold air over Western WA and Northwestern to Southwestern OR. However, by mid week through the end of the work week, the snow level should rise-but remain below pass levels-as one model shows a warm front tracking East by NE over Eastern OR and NW (Olympic Peninsula) to Southern WA (just north of The Dalles area) by sometime Thursday. In the meantime, this indication-mentioned above-has been confirmed as a "winter storm watch" has been posted for the area (as well as others) where 4-8" are expected in the valleys-although the total may be less in this area-and as much as 8-16" in the mountains. In addition, the storm should be accompanied by wind from the SE at 5-15 mph with gusts up to 30 mph. Current conditions for 12/18-mostly clear (widely scattered Altocumulus and Cumulus), no precipitation during the overnight, a heavier layer of ice was noticed on the gauge, the haze is light with very little to no air movement. It is from the North at 0 mph, wind gust: out of the NNW to 17 mph, humidity 72%, dew point 23° (yesterday, the reading was 30°), current snow level is on the surface, observation time temperature was 22°, and the barometric pressure 29.72" and rising. |

The indications of a strong storm arriving over the area by mid week is now a fact. At the present time, this strong storm-centered West of the Queen Charlottes-along with a cold front immediately behind it, is tracking East by NE over Southern BC, Vancouver Island, WA (where one model currently shows a large band of precipitation-with several areas of heavy precipitation contained within it-moving East but from the SW to NE over SW WA to Vancouver Island and the Everett area), most of OR, Northern CA, and is expected to produce heavy rain with up to a half an inch in the lowlands of Western WA and heavy snow in the mountains {as a case in point, Snoqualmie Pass should receive a foot of snow, while Stevens Pass can potentially receive as much as 3 FEET by tomorrow morning!}. By way of contrast however, the WA coast is experiencing windy conditions and heavy rain. Looking ahead, there are indications, after a break early next week, of another "widespread" heavy snow event by "Wednesday/Thursday". In the meantime, "multiple systems passing through the region will lead to periods of snow with variable intensity". Current conditions for 12/19-overcast and snowing! along with little to no wind. It is from the South at 1-2 mph, wind puff: out of the SSE to 4 mph, humidity 86% (yesterday, the reading was 72%), dew point 21°, current snow level is 500' rising to 1500' later this afternoon, observation time temperature was 23°, and the barometric pressure 29.85" and rising. |

With the arrival of the next system, there is the possibility for some snow in this area by sometime today, and rain in Western WA, although both types of precipitation should be light as the worst part of the storm looks to be in Northern CA. Following a brief break tomorrow, the arrival of a stronger system-along with a cold front tacking East by NE toward the coasts of WA, OR, and Northern CA-should arrive by sometime Tuesday. Mid afternoon weather for 12/22-overcast (low clouds and fog-though not on the deck), temperatures are in the mid 30's, BP 29.46"F along with slight air movement from the South.

Yesterday's storm-that brought snow to this area-appears to have weakened and dissipated at the same time as it moved into a weak ridge of high pressure over the area. In the meantime, there is a relatively shallow trough-with its southernmost boundary just off the coast of Southern CA-and immediately behind it, is another ridge of high pressure that could begin to affect our weather (WA) by the end of the work week. Mid afternoon weather for 12/25-overcast and snowing. Temperatures are in the mid 30's, BP 29.72"F along with calm winds.

The next system tracking East by NE toward the coasts of WA and OR-but over the Queen Charlottes and SE AK-should bring some precipitation to the coastal areas of WA sometime later today. In the meantime, even though this area is currently "overcast" with low clouds and fog, above this overcast, it is partly cloudy. Tomorrow should be mostly cloudy followed by a dry week and partly cloudy skies.

The low pressure system-currently off the coast of WA- stretches from northern CA to WA, and is projected to slide South off the Northern CA coast-South of the Bay area-should produce some light rain, mainly along the WA coast (where one model shows a large band of precipitation moving North by NE from over NW OR to the Western side of the Olympic Peninsula). Interestingly, it is associated with a cold front tracking East by SE toward the coasts of Vancouver Island, WA, OR, and Northern CA. With the passage of this system, drier conditions are in store as high pressure begins to build in over the area (WA) by sometime Sunday. Mid afternoon weather for 12/27-little change from earlier in the day as it is still "overcast (low clouds and patchy fog). Temperatures are in the mid to upper 30's, BP 29.95"R along with slight air movement from the South. Current conditions for 12/28-continued overcast (low clouds and patchy fog), moderate haze with little to no air movement. It is from the South at 4 mph, wind puff: is out of the SSE to 6 mph, humidity 88%, dew point 28°, current snow level is near 2000', observation time temperature was 30°, and the barometric pressure 30.05" and rising. |

Yesterday's "system" (stretching from Northern CA to WA, was projected to slide South just off the Northern CA coast-south of the Bay area-has indeed slid South-SW of the Monterey Bay area and is clearly visible on both the WSDOT and UW models) really "broke apart as it moved over the WA coast; however, was strong enough to produce showers along or near the coast. Another low pressure off the NW half of Vancouver Island, should slide South toward Western WA by sometime tonight followed by a dry day tomorrow as a large ridge of high pressure-currently centered West of the Southern OR coast-noses NE toward the coast of WA and builds over the area thereby forcing the storm track well North of the state. The next system should arrive by sometime Sunday evening. Current conditions for 12/29- overcast (a thick Altostratus overcast-the sun is just visible- and widely scattered Cumulus) with a light snowfall, along with very little air movement. It is from the SSW at 0-1 mph, wind puff: out of the SW to 5 mph, humidity 86%, dew point 24°, current snow level is near 1500', observation time temperature was 28°, and the barometric pressure 30.08" and rising. |

The amount shown above occurred after yesterday's observation time (7:40AM). The upcoming work week, for this area, should be dry with partly cloudy skies and little to no chance of precipitation through this period as high pressure-that yesterday was centered West of the Southern OR coast-is now centered off the coast of WA and looks to be firmly established over the PNW while at the same time, will block the next system from coming onshore which, at the present time, looks to be falling apart as the southern half nears the coasts of OR and Northern CA. Meanwhile, even though it will be dry (as mentioned above), there is a chance that this ridge of high pressure could enhance the development of fog in this area. Mid afternoon weather for 12/29-overcast and snowing lightly. Temperatures are in the low to mid 30's, BP 30.00"R along with slight air movement from the East. Current conditions for 12/30-although it is "overcast"-except for some partial clearing to the South-it is mostly a fog event, no precipitation during the overnight, light to moderate haze with little to no air movement. It is from the West at 0 mph, wind puff: out of the WNW to 0 mph, humidity 83%, dew point 23°, current snow level is near 3000' [yesterday, it was near 1500'], observation time temperature was 23°, and the barometric pressure 30.13" and rising. |

Today should remain cloudy; however, tomorrow through the weekend, there is the likelihood of some improvement with partly to mostly cloudy skies before becoming cloudy, once again, early next week. Throughout this period, it will remain dry as high pressure (now centered over NE NV) remains established over WA and OR with indications of remaining through the first half of the weekend although there is a weak-and moisture starved-low pressure (centered off the coast of Southern OR) tracking NE and attempting to move over drier air currently in place in WA and OR. In addition, the storm track will be diverted well north of the area-not as far north as yesterday-over Northern Alberta and Saskatchewan which effectively keeps the coldest Canadian air from the NW. Meanwhile, there are signs of the current high pressure shifting to the East and by sometime this afternoon, another ridge of high pressure should begin to build in over WA. Mid afternoon weather for 1/02-overcast (Stratus?) and patchy fog. Temperatures are in the upper 20's to low 30's, BP 30.44"R along with slight air movement from the South, but occasionally from the SW. Current conditions for 1/03-overcast (and widely scattered patchy fog), no precipitation the last 24, the haze is light with very little air movement. It is from the WNW at 1-2 mph, wind puff: out of the NW to 7 mph, humidity 75%, dew point 19°, current snow level is 6000' lowering to 2500' by later this evening, observation time temperature was 25°, and the barometric pressure 30.30" and falling. |

This morning should be mostly cloudy followed by some improvement this afternoon before becoming cloudy again with the likelihood of some snow showers tomorrow through early next week. Looking ahead to the second half of this month, there are signs "pointing toward waves of frigid air moving southward across North America" which would have the potential to affect this area. Mid afternoon weather for 1/03-overcast and snowing lightly on or near the higher ridges and peaks around the valley. Temperatures are in the upper 20's to low 30's, BP 30.23"F along with light air movement mainly from the NW though occasionally from the North. Current conditions for 1/04-mostly overcast (with some partial clearing), the haze is light to moderate with little to no air movement.

Yesterday, a large mass of clouds were moving North by NE-well West of the WA coast-along with a front that has since moved over WA, OR and Northern CA today-even though a ridge of high pressure is over the area(WA). Interestingly, one model shows a large band of precipitation (a rain/snow mix) moving East by NE and stretching from East of Portland (The Dalles area) to Yakima along with its center (clearly visible) spinning toward the Queen Charlottes southern coast. Mid afternoon weather for 1/04-mostly overcast (Altocumulus and widely scattered patchy fog). Temperatures are in the upper 20's to low 30's, BP 30.27"F along with slight air movement from the North.

The amount shown above was recorded yesterday. Yesterday's system-a slow mover-was not only beginning to move away from its source of energy-a low pressure system centered West of though spinning toward the Southern coast of the Queen Charlottes-but also was breaking up the whole time it moved inland over WA. Following the passage of this system, there will be a break before the next system (with heavier precipitation) "arrives over Western WA by sometime today instead of tomorrow". Meanwhile, with the exception of today being mostly cloudy, tomorrow through mid week will feature cloudy skies and a chance of precipitation in the form of a rain/snow mix (Monday) or just rain. This will be followed by dry conditions, much cooler temperatures, and mostly cloudy skies from the end of the work week through the weekend. Looking ahead to the second half of this month, there continues to be signs "pointing toward waves of frigid air moving southward across North America which would have the likelihood of potentially affecting this area". Mid afternoon weather for 1/05-overcast and snowing . Temperatures are in the upper 20's to low 30's, BP 30.16"F along with slight air movement from the NW. Current conditions for 1/06-overcast (low clouds and fog-though not on the deck. Interestingly, this is the 18th day of "overcast" conditions), no precipitation during the overnight, the haze is light to moderate with little to no air movement. It is from the East at 2 mph, wind puff: out of the ESE to 5 mph, humidity 86%, dew point 27°, current snow level is near 2000' [yesterday, it was near 3500'], observation time temperature was 26°, and the barometric pressure 30.02" and rising. |

Moisture off the Pacific should bring rain to Western WA (though one model shows a band of precipitation-likely in the form of snow-moving East by NE over the Eastern third of WA) and heavy snow to the Cascades as the weather pattern will remain active for the next few days due to a change in the NPJ-which is currently "aimed" at the PNW. Last week (12/29), a big ridge of high pressure-centered West of the southern coast of OR- built in over WA thereby forcing the storm track well North of WA over Northern BC. Meanwhile, after a brief "break", the next storm-stronger than the previous one- should be approaching NW WA (Olympic Peninsula) by sometime tomorrow afternoon and at the same time send a warm front over Western WA along with rain and breezy conditions. Following the passage of the storm, a cold front will "bring a shot of cold air to Western WA" by sometime Wednesday. Mid afternoon weather for 1/06-little improvement from earlier this morning (low clouds and fog), temperatures are in the low 30's, BP 29.98"F along with light air movement from the SE though briefly from the East. Current conditions for 1/07-a foggy overcast, the haze is light with little to no air movement. It is from the West at 0 mph, wind puff: out of the WNW to 3 mph, humidity 90%, dew point 27°, current snow level is near 5500' [ yesterday, it was near 2000'], observation time temperature was 27°, and the barometric pressure 29.83" and falling. |

WOW! The strong wind of last evening significantly reduced the snow pack from 6.8"-at this observation site-to the amount indicated below while at the same time raised the temperature to a high of 50.4°. The strongest low pressure system of the season (centered off the northern coast of WA) with a big flow of moisture from the SW and a very strong NPJ will combine to bring heavy moisture across the NW today along with heavy snow where 3-7" are expected in the "upper Wenatchee River valley, and 1-2' for the East slopes of the Northern Cascades". Earlier in the week, it was mentioned that during the second half of the month, there were signs "pointing toward waves of frigid air moving Southward across North America". The latest update projects it to commence on or near mid week of next week (WA included) and once this frigid air settles in, both the high and low temperatures should stay well below freezing day and night. "Although it appears the cold waves will NOT rival the great arctic outbreaks of January 1994 and 1985 in terms of severity, it is possible that temperatures plunge 40 to 50 degrees over a 24-48 hour period". Current conditions for 1/08-overcast and snowing with very little air movement at the present time. It is out of the East at 1 mph, wind gust: out of the East to 10 mph, humidity 93%, dew point 32°, current snow level is near 3000' rising to 6000' later this afternoon, observation time temperature was 32°, and the barometric pressure 29.95" and rising. |

The amount shown above was recorded yesterday, at the times indicated below. Mid afternoon weather for 1/08- overcast with intermittent showers (rain/snow mix), temperatures are in the mid 30's, BP 29.83" R along with slight air movement from the West and occasionally from the NW. Yesterday's strongest system of the season-with a big flow of moisture from the SW- is in the process of moving East over the Eastern third of WA although the cold front-associated with it-is tracking East by NE over NE to SW WA. As a result, drier conditions and cooler temperatures should prevail by the weekend. Yesterday, one of the main topics of discussion was during the second half of the month there were "signs pointing toward waves of frigid air moving Southward across North America". It would appear that the initial stage for this event may be underway as the NPJ is projected to sag well south of the area (WA) over Southern CA (near the border) by the weekend thereby potentially opening the door for very cold Canadian air to move South over WA, OR, and Southern CA. Current conditions for 1/09-partly cloudy (scattered Cirrus, Altocumulus and Cumulus-quite an improvement from the dense fog earlier this morning), no precipitation during the overnight, and the haze is light with light air movement. It is from the East at 7-8 mph, wind gust: out of the East to 19 mph, humidity 81% (yesterday, the reading was 93%), current snow level is near 4000' lowering to 2500' later this afternoon, observation time temperature was 28°, and the barometric pressure 29.50" and falling. |

Mid afternoon weather for 1/09-mostly clear (scattered Cirrus, Altocumulus, and Cumulus) on a very pleasant winter afternoon. Temperatures are in the mid to upper 40's-or about 10 to 15 degrees above normal for this time of year-BP 29.51"F along with light air movement from the NW. Even though one weather map currently shows low pressure over Western and NE WA while the GFS model shows strong high pressure at the surface-over the Pacific-and aloft over the Gulf region, it appears that this weekend is shaping up to be very cold as the NPJ will be sagging well south of the area (WA) over extreme Northern Mexico thereby opening the door for frigid Canadian air to move South over the Northern Plain states as well as WA and OR. Current conditions for 1/10-mostly clear (widely scattered Cirrus and Cumulus), no precipitation in the last 24, the haze is light with some air movement. It is from the West at 3-5 mph, wind gust: out of the West to 12 mph, humidity 67%, dew point 22°, current snow level is at the surface on the passes, observation time temperature was 30°, and the barometric pressure 29.72" and rising.

Mid afternoon weather for 1/10-mostly clear on another pleasant winter afternoon with scattered Cumulus-near the horizon-from the North to the SW. Temperatures are in the upper 30's to low 40's-which is still about 5 degrees above normal for this time of year-BP 29.77"R along with slight air movement from several directions including the West, NW, and North. Both the GFS and NAM models are showing high pressure at the surface-well West of the OR coast-and aloft over the Gulf region and with the clockwise rotation becomes a contributor for the weekend to be the coldest of of the season so far as the NPJ is currently sagging well south of the area (WA) over Northern Mexico thereby opening the door for the frigid Canadian air to move South over WA and OR. Current conditions for 1/11-mostly cloudy (Altocumulus), the haze is light with little to no air movement. It is from the WNW at 1-3 mph, wind gust: is out of the NW to 11 mph, humidity 60%, dew point 19°, current snow level is at the surface, observation time temperature was 23°, and the barometric pressure 29.97" and rising. |

Mid afternoon weather for 1/11-except for some scattered Cumulus near the Western to Southwestern horizon, we have clear skies. Temperatures are in the mid 30's, BP 30.09"R along with slight air movement from the West and occasionally from the SW. With strong high pressure firmly established over the Gulf and AK, and the Southernmost boundary of the NPJ now sagging over Northern Mexico and central Baja, CA, the door is now open for frigid Arctic air to "invade" not only WA and OR, but also the "Desert SW and Southern CA". Looking ahead, the upcoming week should feature milder conditions at higher elevations, high pressure and dry conditions with the likelihood of low clouds and fog (or an inversion). Current conditions for 1/12-mostly clear with what appears to be Cirrocumulus Undulatus, the haze is light, no precipitation in the last 24, along with light air movement. It is from the NNE at 1-4 mph, wind puff: out of the NE to 7 mph, humidity 76%, dew point 13°, current snow level is near 1000' [yesterday it was at the surface}, observation time temperature was 13°, and the barometric pressure 30.18" and rising. |

Mid afternoon weather for 1/12-a beautiful but clear and cold winter afternoon! Temperatures are in the mid to upper 20's, BP 30.21"R along with light air movement mainly from three directions including the West, NW, and North though occasionally from the SE. In what appears to be a "pineapple express" of sorts, extends from the SW (North of HI) to NE over the middle to inner Aleutians, then bears East by NE over Southern AK and the Yukon before turning SE over NW BC. If it were not for the strong ridge of high currently over the Gulf and AK-although it has strengthened somewhat and moved slightly East over Western WA and OR since yesterday-the area (WA) would likely be experiencing warmer conditions instead of the frigid air currently in place. Looking ahead, the upcoming week should feature change as strong high pressure (mentioned above) should be directly over WA which will likely result in dry conditions along with the probability of low clouds and fog (an inversion). Current conditions for 1/13-partly cloudy (scattered Cirrus, Cirrostratus-including a sun dog-and Altocumulus), light haze, no precipitation in the last 24, and light air movement. Earlier, it was from the East at 0 mph, wind puff: out of the East to 8 mph, humidity 73%, dew point 9°, current snow level is near 1000', observation time temperature was 10°, and the barometric pressure 30.26" and rising. |

Mid afternoon weather for 1/13-mostly clear (scattered Cirrus and a large deck of semi-transparent Altocumulus which was spreading from the West to the SW toward the East). Temperatures are in the mid to upper 20's, BP 30.30"R along with light air movement mainly from the North. The strong ridge of high pressure that yesterday was over the Gulf and AK, has since strengthened (with its center now West of the WA/OR coast) and moved inland over WA resulting in dry conditions for most of the week as this strong high pressure has forced the NPJ well North of the area (WA) which should cause temperatures to moderate as the week progresses especially over and West of the Cascades where "milder conditions" will prevail due to a "warmer air mass" while "central and eastern WA" will likely entertain the probability of low clouds and fog during the same period. Interestingly, the freezing level is projected to rise abruptly from tomorrow evening through the weekend to a maximum level of 9000'-10,000'. Current conditions for 1/14-mostly clear (scattered Cirrus, Cumulus and patchy fog), no precipitation in the last 24, the haze is moderate with little to no air movement. It is from the South at 4-5 mph, wind gust: out of the SSW to 10 mph, humidity 70%, dew point 16°, current freezing level is near 2000' [yesterday, it was near 1000'], observation time temperature was 22°, and the barometric pressure 30.22" and rising. |

Mid afternoon weather for 1/14-mostly overcast (scattered Cirrostratus and Altostratus), temperatures are in the upper 20's to low 30's, BP 30.22"R along with light air movement from the North though occasionally from the NE. With the strongest high pressure of the "winter season" now firmly established over the area (WA)-and accompanied by very dry air moving inland over Western WA, OR, and Northern CA-through the weekend, two "events" should become apparent. The first one, of course, is that the NPJ has been forced well north of the area (WA) thereby preventing any further frigid Canadian air-including a reinforcing shot-from invading the NW for the time being. Because of this strong high pressure, air stagnation becomes a probable factor "in the next few days" over Eastern WA due to "stable conditions", warm air aloft, and cold air trapped near the surface with little or no "wind" to mix or move this air around (second event). Current conditions for 1/15-partly cloudy (scattered Cirrus and Cirrostratus along with patchy fog), no precipitation in the last 24, the haze is moderate to bad with little to no air movement. It is from the East at 0 mph, wind puff: also out of the East to 4 mph, humidity 86% [yesterday, the reading was 70%], current freezing level is 6000' rising to 10,000' later this afternoon, observation time temperature was 15°, and the barometric pressure 30.40" and rising. |

Mid afternoon weather for 1/15-mostly clear (widely scattered Cirrus and Cirrostratus near the Eastern and Southern horizon), temperatures are in the upper 20's to low 30's, BP 30.44"R along with air movement mainly from the North though occasionally from the NW. Because strong high pressure-with its center off the Northern CA coast-will remain firmly established over the area (WA) through the end of the work week, any further frigid Canadian air-including a reinforcing shot-will be prevented from invading the NW as the NPJ is still well North of the area over the Gulf, SE AK, and Northern BC "which is unusual for this time of year". As a result, air stagnation is now a factor in most of Eastern WA due to "very stable conditions, warm air aloft and cold air trapped near the surface with "little to no 'wind' to mix or move the air around". In response to the "warmer air aloft", the freezing level will hover between 10,000'-10,500' from today through the first half of the weekend before rising to a maximum level of 11,000'-11,500' from Sunday evening through early next week. Above this inversion however, partly to mostly cloudy conditions should be the norm for the second half of the work week {including the weekend}. Current conditions for 1/16-"overcast" (low clouds and fog-an inversion), no precipitation in the last 24, the haze is moderate to bad with little to no air movement. It is from the South at 0-2 mph, wind puff: out of the SSW to 5 mph, humidity 80%, dew point 19°, current freezing level is near 10,500', observation time temperature was 23°, and the barometric pressure 30.45" and rising. |

Mid afternoon weather for 1/16-"overcast" (low clouds and fog-though not on the deck. However, above this inversion, it is partly to mostly cloudy). Temperatures are in the upper 20's to low 30's, BP 30.45"R along with slight air movement from the West. Strong high pressure-centered off the coast of Northern CA near the Bay area) will continue to foster dry conditions and remain well established over the area (WA) through the weekend and as a result, continues to keep the NPJ north of the area (Northern BC and Alberta), but not as far as yesterday. Because of this high pressure and the time of year, air stagnation continues to be a factor in most of Eastern WA due to "very stable" conditions, warmer air aloft, and cold air trapped near the surface with little to no "wind to mix or move the air around". Consequently, this current pattern is likely to persist through the weekend although partly to mostly cloudy skies should prevail above this inversion. Current conditions for 1/17-"overcast" (low clouds and fog-though not on the deck), the haze is moderate, no precipitation in the last 24, and very little to no air movement. It is from the West at 2-3 mph, wind puff: is out of the WSW to 8 mph, humidity 77%, dew point 21°, current snow level is near 9000' [yesterday, it was near 10,500'], observation time temperature was 26° and the barometric pressure 30.42" and rising. |

After several measurements were taken yesterday, it was determined that the average snow depth is 4.0" Mid afternoon weather for 1/17-"overcast" (low clouds and fog-though not on the deck), temperatures are in the upper 20's to low 30's, BP 30.34"F along with slight air movement from the NW. Air stagnation will continue to be a factor in most of Eastern WA due to "very stable" conditions, warmer air aloft, and cold air trapped near the surface with "little to no wind to mix or move the air around" as strong high pressure (currently centered off the coast of northern CA) should continue to foster dry conditions and remain well established over the area (WA) through early next week (even though it has flattened somewhat since yesterday, and the air flow is zonal across most of the Gulf) thereby keeping the NPJ well north of the area over Northern BC and Alberta consequently preventing any frigid Canadian air-now east of the area where one weather map shows "brutally cold" air invading the Midwest-from moving over the NW. Above this inversion however, mostly cloudy to overcast conditions should prevail today through the weekend. Current conditions for 1/18-"overcast" (low clouds and fog-though not on the deck), no precipitation in the last 24, the haze is moderate to bad with little to no air movement. It is from the WNW at 1-2 mph, wind puff: out of the NW to 6 mph, humidity 83%, dew point 22°, current snow level is near 9000', observation time temperature was 25°, and the barometric pressure 30.19" and falling. |

Mid afternoon weather for 1/18-"overcast" (low clouds and fog-though not on the deck), temperatures are in the upper 20's to low 30's, BP 30.16"F along with slight air movement from the West and South, but from the North, the movement was slightly stronger. The persistent ridge of strong high pressure-along with very dry air moving inland over CA, most of OR and SW WA-currently off the NW CA coast will "peak this weekend by building right over WA" which will further amplify the inversion-will continue to remain well established over the area through early next week {thus keeping the NPJ well north of WA- over the Queen Charlottes and Northern BC} and as a result, "very stable" conditions, warmer air aloft, cold air trapped near the surface, and air stagnation-because of "little to no wind to mix or move the air around" will also be very tenacious through this period. Above this inversion, partly to mostly cloudy skies should be the norm for today through early next week with very little chance of any precipitation. Current conditions for 1/19-"overcast" (low clouds and fog-though not on the deck), no precipitation in the last 24, the haze is moderate to bad with little to no air movement. It is from the East at 0 mph, wind puff: out of the ENE to 4 mph, humidity 78%, dew point 21°, current snow level is near 9500', observation time temperature was 25°, and the barometric pressure 30.26" and falling. |

Mid afternoon weather for 1/19-mostly cloudy-a pleasant relief indeed from the gloom of the past several days-(scattered Cirrus, Cirrostratus, Altostratus and Altocumulus), temperatures are in the low to mid 30's, BP 30.28"F along with some light air movement mainly from the North and NE. Although a welcome reprieve was enjoyed from the gloom of low clouds and fog yesterday afternoon into the early evening hours, these conditions-just mentioned-quickly resumed later the same evening as strong high pressure (centered off the WA/OR coast) already over the area for the past several days, appears to have strengthened somewhat which would, in effect, serve to "further amplify the inversion" and, as a result, there would be "little change from the past few days". Looking ahead however, the days are now numbered for this inversion as the current ridge of high pressure over the area(WA) finally moves east thus allowing a system (not particularly strong) to move inland over Western WA that should scour the remaining cold air and "draw the snow level back down to near pass level" while at the same time bring a chance of precipitation to this area along with wind to scour the remaining cold air from the valley by mid week. Current conditions for 1/20-"overcast" (low clouds and fog-though not on the deck-although the higher ridges and mountains are completely obscured from view), no precipitation in the last 24, the haze continues to be moderate to bad with little to no air movement. It is from the WNW at 1-4 mph, wind puff: out of the NW to 7 mph, humidity 86%, dew point 20°, current freezing level is near 10,500' [yesterday, it was near 9500'], observation time temperature was 22°, and the barometric pressure 30.38" and rising. |

High pressure should remain over the area (WA) for one more day and keep the persistent low clouds and fog, or inversion (comprised of "very stable" conditions, warmer air aloft, cold air trapped near the surface, and air stagnation) engine running for another day before a "major pattern change is on the way for the NW that should last through the weekend. What is responsible for this "change"? The ridge of high pressure-currently over (WA)-will finally move East thereby allowing the first system (in what appears to be a series) to move inland over Western WA and effectively "draw the snow level back down to near pass level". Interestingly, even though the current freezing level was near 11,500' yesterday-which is unusually high for this time of year-it should begin to lower today and reach a minimum level of near 2000' by sometime Thursday. In the meantime, this system-mentioned above-will bring a chance of precipitation to this area along with some wind that should scour out the cold air trapped near the surface thus bringing a welcome end to this tenacious inversion with "warmer and dry conditions for the interior NW" by the end of the work week. Current conditions for 1/22-"overcast" (low clouds and fog-though not on the deck), no precipitation in the last 24, the haze is moderate to bad with little to no air movement. It is from the North at 0-2 mph, wind puff: out of the NNE to 6 mph, humidity 78%, dew point 15° {yesterday, the readings were 89% and 19° respectively}, current snow level is near 10,000' [yesterday, it was near 11,500'], observation time temperature was 20°, and the barometric pressure was 30.20" and falling. |

Mid afternoon weather for 1/22-overcast with patchy fog. Temperatures are in the upper 20's to low 30's, BP 30.15"F along with light air movement from both the West and NW. Although high pressure remains over the area (WA)-though its axis is east of the region-there are indications that this tenacious inversion is in the initial stages of finally releasing its grip as a "fast moving cold front" will track through the area and with its passage, generate some air movement that should scour out cold air trapped near the surface. In the meantime, a system has arrived over Western WA where one model shows a large band of precipitation moving North by NE over NW OR to most of Western WA. Current conditions for 1/23-overcast (Stratus and patchy fog), no precipitation in the last 24, the haze is moderate to bad with little to no air movement. It is from the WNW at 2 mph, wind puff: out of the NW to 7 mph, humidity 75%, dew point 18°, current snow level is near 3000' [yesterday, it was near 10,000'!], observation time temperature was 23°, and the barometric pressure 30.00" and falling. |

The amount shown above was recorded yesterday during the time indicated below. Mid afternoon weather for 1/23-except for partial clearing to the NW, we have overcast skies (Altocumulus and patchy fog), temperatures are in the low 30's, BP 29.86"F along with light air movement from the North. Yesterday's cold front succeeded in scouring out the cold air trapped near the surface; however,it appears that "inversion-like" conditions returned to central Eastern WA with weak high pressure, low clouds and fog, and cold air trapped near the surface. The next system (currently tracking East by NE over NW WA, Vancouver Island, SW and the central coast of BC and most of the Queen Charlottes) is spreading moister air ahead of it over WA-where one model shows a band of precipitation moving East by NE toward the coasts of WA and SE Vancouver Island-and most of OR. Interestingly, the outlook for this area calls for partly to mostly cloudy conditions today through the weekend with a chance of precipitation today and tomorrow. Meanwhile, the deep trough that was "forecast" to arrive over (WA) by the weekend should, in fact, take place early next week as the ECMWF model shows the southernmost boundary over central Baja during this period. Current conditions for 1/24-overcast (low clouds and fog-though not on the deck), the haze is moderate to bad with little to no air movement. It is from the East at 1-4 mph, wind puff: out of the ESE to 5 mph, humidity 87% {yesterday, the reading was 75%}, dew point 21°, current snow level is near 2000' [yesterday, it was near 3000'], observation time temperature was 22°, and the barometric pressure 30.08" and rising. |

The amount shown above was recorded sometime last evening. Mid afternoon weather for 1/24-"overcast" (low clouds and fog-though not on the deck), temperatures are in the low 30's, BP 30.09"R along with light air movement from the West and North. A few changes are in store for the NW by early next week as the current trough off the coasts of WA and OR well develop into a deeper trough with the southernmost boundary extending over central Baja, CA as shown by the ECMWF, GFS and NAM models. This should open the door, once again, for a colder air pattern to return to the area along with the likelihood of "occasional snow for the interior NW". In the meantime, low pressure over the Gulf-with the center near SE AK-is accompanied by a "good flow of moisture" that should bring showers to Western WA today {although one model show several bands of precipitation moving East by NE over SW, NW and NE OR as well as SW and SE WA}. Current conditions for 1/25-partly cloudy (scattered Cirrus, Altocumulus, Cumulus and patchy fog), the haze is moderate along with little to no air movement. It is from the North at 1-2 mph, wind puff: out of the NNE to 5 mph, humidity 87%, dew point 21°, current snow level is near 4500' [yesterday, it was near 2000'], observation time temperature was 20°, and the barometric pressure 29.98" and falling. |

The amount shown was recorded at some point during the overnight. Mid afternoon weather for 1/25-overcast and patchy fog. Temperatures are in the mid 30's, BP 29.89"F along with the slightest of air movement from the North. Changes continue to be in store for the NW as yesterday's trough that was off the coast of WA and OR will have moved inland over Western WA and OR as well as most of CA by early next week and developed into a deep trough with the southernmost boundary now over Northern Baja, CA as shown by the ECMWF, GFS and NAM models. This will open the door, once again, for much cooler air to return to the area along with the likelihood of occasional snow for the interior NW. Meanwhile, one model shows low pressure-just off the SW coast of Vancouver Island-tracking East by SE and sending scattered showers over NW OR and Western WA along with a band of precipitation from Bellevue to Bellingham that includes a pocket of more intense precipitation from the Lake Stevens area to Marysville, and another south of Mt. Vernon. Following the passage of this trough, there are indications that a strong ridge of high pressure will build over the area by mid week and remain through the end of the work week with the likelihood of yet another inversion. Current conditions for 1/26-"overcast" (low clouds and fog-though not on the deck), the haze appears to be moderate with little to no air movement. It is from the East at 0 mph, wind puff: out of the East to 5 mph, humidity 86%, dew point 26°, current snow level is near 2500' [yesterday, it was near 4500'], observation time temperature was 28°, and the barometric pressure 29.80" and falling. |

Mid afternoon weather for 1/26-overcast (low clouds and fog but not on the deck), temperatures are in the mid 30's, BP 29.80"F along with light air movement from the South. This observer has been "watching" the trough of the past few days, and according to the ECMWF, GFS and NAM models will continue to develop into a deep trough with the southernmost boundary over Northern Baja, CA by early this week which should allow, once again, for much cooler air to return to the area. Following the passage of the trough, there are indications that a strong ridge of high pressure will build over the area (WA) by mid week and remain through the upcoming weekend thus increasing the likelihood of yet another inversion (which would include "very stable" conditions, warmer air aloft, cold air trapped near the surface, and air stagnation as a result of little to no wind to mix or move the air around.

Mid afternoon weather for 1/27-a somewhat thicker "overcast" since this morning (low clouds and fog, but not on the deck), temperatures are in the mid 30's, BP 29.84"F along with slight air movement from the West. The ECMWF, GFS and NAM models continue to show the trough, of the past few days, developing into a deep trough with the southernmost boundary over central Baja, CA by sometime tomorrow. In the meantime, unsettled weather will be the norm for today and tomorrow as one system should affect the Cascades and Olympics today and tonight where one model currently shows a very large band of precipitation from NW OR to NW WA with a pocket of more intense precipitation over the Everett/Marysville area. Following quickly on the heels of the first one, a second-larger and stronger-system will arrive "Tuesday afternoon through Tuesday evening" resulting in heavy snow for the Cascades and Olympics of WA and OR where 2-4 FEET are expected, but only 1-3 FEET at pass level before a strong ridge of high pressure builds over the area by mid week and should remain through the weekend along with the probability of another inversion:( in the lowlands of Eastern WA. Although this high pressure should produce stable conditions and warmer air aloft, cold air will be trapped near the surface that will enhance the likelihood of air stagnation because of little to no wind to mix or move the air around. Current conditions for 1/28-overcast (thicker Altostratus and widely scattered Cumulus), no precipitation during the overnight, the haze is moderate to bad with little to no air movement. It is from the WNW at 0-2 mph, wind puff: out of the NW to 7 mph, humidity 86%, dew point 25°, current snow level is near 2000', observation time temperature was 27°, and the barometric pressure 29.81" and falling. |

According to the ECMWF, GFS and NAM models, the trough of the past several days has finally reached its zenith with the southernmost boundary now over central Baja, CA! In the meantime, a ridge of high pressure-currently over the Gulf- moved further East toward WA and strengthened considerably since yesterday (with its apex now over SE AK and the SE portion of the Yukon). This strong ridge of high pressure will move over the area sometime tomorrow and remain through the weekend keeping the area dry through this period. Due to this strong ridge of high pressure, there is the likelihood of another inversion for the lowlands of Eastern WA as it-the high pressure-will generate very stable conditions and warmer aloft while colder air will be trapped near the surface further amplifying the probability of air stagnation since there will be little or no wind to mix or move the air around. Meanwhile, a second disturbance will "drop SE from BC" and bring heavy snow "to the central Cascades at higher elevations" through tomorrow where 1-2 additional FEET are expected along with a gradual rise in the snow level today and tomorrow (4000'and 5000' respectively). Current conditions for 1/29-mostly cloudy (Altocumulus and scattered Cumulus), no precipitation in the last 24, the haze continues to be moderate to bad with little to no air movement. It is from the East at 0-6 mph, wind puff: out of the ESE to 5 mph, humidity 75% {yesterday, it was 86%}, dew point 27°, current snow level is 3000' rising to 4000' later this afternoon, observation time temperature was 28°, and the barometric pressure 29.89" and falling. |

Mid afternoon weather for 1/29-partly cloudy (scattered Cirrus and Altocumulus), temperatures are in the mid 40's, BP 30.03"R along with slight air movement from the South. Yesterday's strong ridge of high pressure over the Gulf region with its apex over SE AK and the SW portion of the Yukon has since moved over WA (although its axis remains off the West coast), will remain through the weekend, strengthened in the process, and will more than likely result in dry conditions during this period. In the meantime however, "several fast moving weak disturbances" will affect Western WA as one low pressure is shown over NW OR {although one model shows a large band of precipitation extending NW to SE from Aberdeen, WA to East of Salem, OR. Within this band, is a long band of more intense precipitation extending SE to NW from NW of Mt. St. Helens to just West of Morton}, another over Southeastern Vancouver Island, and a third SW of the Queen Charlottes. Current conditions for 1/30-mostly clear (scattered Cirrus and Altostratus), no precipitation in the last 24, the haze is moderate along with little to no air movement. It is from the North at 5-6 mph, wind gust: out of the NNE to 26 mph, humidity 51%, dew point 34° (yesterday, the readings were 75% and 27° respectively), current snow level is 4000' rising to 5000' later this afternoon, observation time temperature was 40°-or about 17 degrees above normal for this time of year! and the barometric pressure 29.98" and rising. |

Mid afternoon weather for 1/30-mostly cloudy (scattered Cirrus and Cirrostratus), temperatures are in the mid to upper 50's-which is about 18 degrees above normal for this time of year-BP 30.01"R along with air movement from the NW. Today should feature showers and clouds as one last but weak disturbance moves through Western WA (where one model shows light precipitation over the SW side of the Olympic Peninsula while a narrow, lengthy band of precipitation is tracking East by SE from NW OR to Lake Stevens)-along with a moderate sized pocket of more intense precipitation from just north of North Bend to Sultan, and from there, scattered showers to the NW border of WA-before conditions become drier this weekend as high pressure should be firmly established over the area (WA) during this period. As a result, there is the probability of another inversion in the lowlands of Eastern WA due to the dry and stable conditions this high pressure will cause. In addition, low clouds, air stagnation and cooler air trapped near the surface may very well become a reality. Current conditions for 1/31-overcast except for some partial clearing to the North, no precipitation in the past 24, the haze is moderate with little or no air movement. It is from the West at 2-4 mph, wind puff: is out of the WSW to 8 mph, humidity 88% {yesterday, it was 51%}, dew point 31°, current snow level is near 4000' [yesterday, it was near 5000'], observation time temperature was 31°, and the barometric pressure 30.09" and rising. |

Current conditions for 2/01-partly cloudy (scattered Cirrus, Cirrostratus and Altocumulus), no precipitation in the last 24; however, a "thicker" veneer of frost and ice was observed this morning on the gauge, the haze is moderate to bad although there is some air movement. It is from the WNW at 0-3 mph, wind gust: out of the NW to 11 mph, humidity 83%, dew point 29°, current snow level is 5500' {yesterday, it was near 4000'} rising to 7500' by this evening, observation time temperature was 30°, and the barometric pressure 30.15" and rising. |

Temperatures are in the mid to upper 30's,BP 30.24" and rising along with some air movement from the North. Current conditions for 2/03-"overcast" (low clouds and fog near the deck with the higher ridges and mountains around the valley totally obscured from view), no precipitation during the overnight, and little to no air movement to move or mix the air around. It is from the WNW at 1-3 mph, wind puff: out of the NW to 7 mph, humidity 97%, dew point 28°, current snow level is near 5500', and the observation time temperature was 28°.

Mid afternoon weather for 2/04-overcast (Cirrostratus), temperatures are in the low 40's, BP 29.91"F along with slight air movement from the South. Although a couple of weak disturbances will move through WA this week which will result in "rain for Western WA, but snow or rain and cooling to the mountains", the bigger story is another ridge of high pressure that will become firmly established over the area (WA) by this upcoming weekend and likely remain through mid month. However, because the days are now remaining light for a longer period of time, the possibility of a prolonged inversion is unlikely. Current conditions for 2/05-"overcast" (low clouds and fog to such an extent that the higher ridges and mountains around the valley are completely obscured from view), the haze continues to be very bad with little or no wind to move or mix the air around.

Mid afternoon weather for 2/05-partly cloudy (scattered Cirrus, Cirrostratus and Cumulus), temperatures are in the low 40's, BP 29.67"F along with very slight air movement from the South. It appears that the trough, currently off the West coast, will continue to move SE with its southwestern boundary over NW Mexico by sometime Saturday. This will impact the ridge of high pressure to some extent because even though it is relatively large, its axis is well off the West coast and instead of being firmly established over the area by the weekend as previously thought, it looks as though WA and OR will be on the eastern "fringes" of this ridge of high pressure. Current conditions for 2/06-overcast (Cirrostratus and Cumulus), no precipitation in the last 24, a heavy frost was observed earlier this morning on the gauge as well as the ground, the haze remains bad with little or no air movement. It is from the East at 5 mph, wind puff: out of the ENE to 7 mph, humidity 88%, dew point 33°, current snow level is near 2500' [yesterday, it was near 3500'], observation time temperature was 31°, and the barometric pressure 29.86" and rising. |

Mid afternoon weather for 2/12-partly cloudy (scattered Cirrus and Cumulus), temperatures are in the upper 40's to low 50's, BP 30.06"R along with calm winds. One model (SSEC) shows "energy" attempting to move through a ridge of high pressure {currently off the West coast with its apex over the Gulf region} into WA, but dissipating in the process while the main "energy" is riding up and over this ridge into SE AK, the Queen Charlottes and BC. However, by tomorrow this high pressure will establish itself over the area (WA) and remain through the end of the work week before breaking down and moving East of the area. Current conditions for 2/13-overcast (Cirrus, Cirrostratus, a huge halo, and some Altocumulus to the South), there was a light frost on the ground and gauge earlier this morning, no precipitation in the last 24, the haze is moderate with little or no air movement.

Although both the GFS and NAM models show high pressure over the area (though its axis still remains off the West coast) with its apex over SE AK, there are indications that this ridge should strengthen somewhat today and tomorrow before it commences to break down and move East of the area (WA) by sometime Saturday. Current conditions for 2/14-partly cloudy (Cirrus, a few dense Cirrus and Altocumulus), no precipitation in the last 24, the haze is light to moderate with little or no wind to move it around.

Mid afternoon weather for 2/14-partly cloudy (scattered Cirrus and Altocumulus), temperatures are in the low 50's, BP 30.28"R along with some light air movement from the NW. High pressure has indeed strengthened somewhat since yesterday, and should remain over the area for the rest of the day before it commences to break down and move East by sometime tomorrow. This will allow a weak system-along with a cold front-to arrive over the area by sometime Sunday which should result in some precipitation, cooler temperatures and a lower snow level. This will be followed by a second-though much deeper-trough early next week and it is projected to remain over the area for a couple of days. Current conditions for 2/15-mostly clear (widely scattered Cirrus and a few contrails), no precipitation in the last 24, the haze is light to moderate with little or no air movement. It is from the WNW at 2 mph, wind puff: out of the NW to 5 mph, humidity 71%, dew point 29°, current snow level is near 7500' [yesterday, it was near 4000'], observation time temperature was 33°, and the barometric pressure 30.39" and rising. |

Mid afternoon weather for 2/15-clear skies, temperatures are in the mid 50's, BP 30.22"R along with some air movement from the NW though occasionally from the NE. High pressure over the area for the past few days, is in the process of breaking down and moving East of the area due to a shallow trough currently off the coasts of Vancouver Island, WA and northern OR and is projected to move over WA by sometime tomorrow. As a result, weak low pressure-within the trough-and a cold front associated with it should bring some precipitation to Western WA, along with cooler temperatures and a lower snow level with the passage of this weak low pressure sometime tomorrow. Current conditions for 2/16-mostly clear (a large sheet of Altocumulus from the South to the East, and scattered Cumulus), no precipitation in the past 24, the haze is moderate with little or no wind to mix or move the air around. It is from the WNW at 1 mph, wind puff: out of the NW to 6 mph, humidity 86%, dew point 31°, current snow level is near 4500' [yesterday, it was near 7500'], observation time temperature was 29° and the barometric pressure 30.01" and rising. |

Mid afternoon weather for 2/16-mostly clear (scattered Cumulus), temperatures are in the mid 50's-which is about 10 degrees above average for February-BP 29.81"F along with some air movement from the NW as well as the SW. The shallow trough that yesterday was off the coasts of Vancouver Island, WA, northern OR, and was projected to move over the area by sometime today is already East of WA and in its place, high pressure is already attempting to build over WA; however, its presence will be short lived (today and tomorrow) as a second- but much deeper than the first one-trough begins to move over the area early next week with the Southwestern most boundary near the southern CA border. In addition, it appears that any moisture associated with this "trough" will remain south of WA. Current conditions for 2/17-mostly clear (scattered Cumulus), no pecipitation in the last 24, the haze is light to moderate with some air movement. It is from the West at 3 mph, wind gust: out of the WNW to 10 mph, humidity 52% {yesterday, the reading was 86%}, dew point 27°, current snow level is near 1500' [yesterday, it was near 4500'], observation time temperature was 36°, and the barometric pressure 29.94" and rising. |

Mid afternoon weather for 2/17-partly cloudy (a large halo, several contrails, scattered Cirrus, Cirrostratus and Cumulus), temperatures are in the mid 50's, BP 29.92"R along with some air movement from several directions including the West, NW and NE. An upper level low-currently off the NW coast of WA (Olympic Peninsula) will bring cooler temperatures and below average highs to Western WA through much of this week. One model already shows scattered showers moving East over NW OR, while tracking North by NE over SE Vancouver Island, BC and the coast of WA with one band approaching the Olympic Peninsula. In the meantime, the "trough" off the coasts of WA and OR, will continue to slide SE until mid week when at that time, its Southernmost boundary should be near the southern CA border. Looking ahead to the end of the work week, although there is a possibility of heavy precipitation in the form of rain in the lowlands of Western WA, and snow in the Cascades, it is believed that moisture associated with this "trough" will remain south of WA. Current conditions for 2/18-overcast (dense Cirrostratus and scattered Cumulus), no precipitation in the last 24, the haze is light to moderate along with some light air movement. Although the wind is from the WNW at 0 mph, it has picked up somewhat since earlier this morning, wind puff: out of the NW to 7 mph, humidity 77% (yesterday, the reading was 52%), dew point 25°, current snow level is near 1500', observation time temperature was 27°, and the barometric pressure 29.89" and rising.

Mid afternoon weather for 2/18-overcast (dense Cirrostratus and scattered Cumulus), temperatures are in the upper 30's to low 40's, BP 29.71"F along with light air movement from both the North and NE. The "trough" continues to slide SE with its Southernmost boundary currently over the coast of Northern CA along with low pressure that yesterday was centered off the tip of NW Vancouver Island but has, since then, moved South off the Southern OR coast. This pattern will continue through tomorrow when, at that time, its Southernmost boundary will be near the southern CA border. Low pressure now centered over northern CA (west of Lake Tahoe) will continue tracking further SE to arrive over southern CA near the CA border. As a case in point, one model is showing a narrow strip of heavy snow where 1-2' are expected in the Sierra Nevada and Cascades of Northern CA while 6-10" (above 4500') are likely in the San Gabriel mountains near LA! Current conditions for 2/19-partly cloudy (scattered Altocumulus and Cumulus), no precipitation in the last 24, the haze is light to moderate with little to no air movement. It is from the WNW at 2-4 mph, wind puff: out of the NW to 7 mph, humidity 69%, dew point 27°, current snow level is near 1500', observation time temperature was 34°, and the barometric pressure 29.64" and falling. |

Mid afternoon weather for 2/19-mostly cloudy (scattered Altocumulus and Cumulus), temperatures are in the upper 40's to low 50's, BP 29.63"F along with air movement from the NE. With the passage of the deep trough yesterday, cooler conditions can be expected; however, as previously stated for the past few days, most of the energy will remain south of WA although a much stronger front will move through the area Friday bringing heavy snow to the mountains where 1-2 FEET (Northern Cascades) is expected by Saturday morning. In addition, "breezy to windy conditions are also expected over the lowlands as the front moves through". Current conditions for 2/20-mostly cloudy (scattered Cirrus, Cirrostratus and a few contrails), no precipitation in the last 24, the haze is light to moderate with little or no air movement. It is from the WNW at 0 mph, wind puff: out of the NW to 7 mph, humidity 64%, dew point 25°, current snow level is near 2000', observation time temperature was 28°, and the barometric pressure 29.86" and rising. |

Although the weather should remain relatively dry for most of Eastern WA today, the first system (with low pressure centered over SW BC) will bring rain to the lowlands of Western WA and snow in the Cascades where a "winter advisory" has been posted from 4AM today-4AM Friday as 6-14" are expected in the passes. This will be followed by a much stronger system-along with a strong cold front tracking East by SE toward WA-where a "winter storm watch" has been posted from Friday AM through SAT AM as 1-2 FEET and possibly even 3' are expected in the Cascades and Olympics. In additions to areas of heavy rain {where one model currently shows precipitation moving East by SE over NW OR, South central and Southwestern WA, a couple of small bands over the Sedro Wooley and NW WA-Bellingham area-and finally a band of precipitation moving across the Olympic Peninsula with three pockets of moderate precipitation North and NW of the Aberdeen, WA area} in Western WA, and snow in the mountains, "breezy to windy" conditions will accompany this system over the lowlands as the front moves through. Current conditions for 2/21-partly cloudy (scattered Cumulus), no precipitation in the last 24, the haze is moderate with little or no air movement. It is from the West at 0-2 mph, wind puff: out of the West to 5 mph, humidity 78% (yesterday, the reading was 64%), dew point 26°, current snow level is near 2000', observation time temperature was 26°, and the barometric pressure 29.85" and rising. |

Mid afternoon weather for 2/21-mostly cloudy (scattered Altocumulus and Cumulus). The NW and SW are ominous in appearance as it is snowing on or near Mission Ridge. Temperatures are in the upper 40's to low 50's, BP 29.79"R along with light air movement from both the SE and East. Current conditions for 2/22-overcast (although it is snowing on the higher elevations around the valley, it is currently raining and thus a trace has been recorded so far), with little or no air movement. It is from the West at 2 mph, wind puff: out of the WNW to 8 mph, humidity 78%, dew point 31°, current snow level is near 2000' rising to 3000' later this afternoon, observation time temperature was 33°, and the barometric pressure 29.77" and rising. The next report will be on 2/25 as this observer will be in Spokane for an AAU basketball tournament. |

A relatively large trough moved inland today over WA, OR, northern CA, and NW NV, forcing the bulk of the "weather" ahead of it over southern Alberta, most of MT, ID and NE to SW NV. Meanwhile, low pressure {over SE Vancouver Island appears to be responsible for "windy conditions" and "rain showers" in Western WA as well as heavy snow in the mountains where an additional 5-10" are expected "through this afternoon". One model is showing scattered showers in NW OR and Southwestern WA, but the largest band of precipitation-moving East by NE-extends SE to NW over the Arlington to Bellingham area} along with a cold front tracking East by SE over Western WA and NW OR. This will be followed by a dry period-due to weak high pressure over the Eastern Gulf-before the next low pressure (also accompanied by a cold front tracking the same direction as the one mentioned above) arrives over Western WA late Tuesday into early Wednesday with another chance for more rain showers. Current conditions for 2/25-mostly cloudy (scattered Altocumulus and Cumulus-the dominant variety), the haze is light to moderate along with some air movement. It is from the WNW at 2-3 mph, wind puff: out of the NW to 6 mph, humidity 76%, dew point 32°, current snow level is near 2000', observation time temperature was 29°, and the barometric pressure 29.75" and rising.

Mid afternoon weather for 2/25-mostly cloudy (scattered Cirrostratus, Altocumulus and Cumulus), temperatures are in the mid 50's-which is still about 7 degrees above average for this day in February-BP 29.76F along with a nice breeze from the North. A relatively large trough moving East by NE-with its southeastern boundary off the West coast of WA-is forcing a large system ahead of it over the Queen Charlottes, central coast of BC, Vancouver Island and NW WA (Olympic Peninsula). In the meantime, weak high pressure centered over Northern OR {near the WA border-South of Tri-Cities} will be of short duration as the next low pressure-centered just West of the Queen Charlottes-along with a cold front tracking East by SE (which will weaken as it approaches the coast) should arrive later this evening in Western WA with rain showers. However, looking ahead to the end of the work week, some "big changes" are in the offing as the "flow will turn southwesterly" in the form of a "pineapple express" thereby setting up a possibility of heavy rain in NW WA. In addition, there are indications of "significant warming" during this period. Current conditions for 2/26-mostly cloudy (Cirrus, Cirrostratus and a large halo), no precipitation in the last 24, light to moderate haze along with a little air movement. It is from the West at 6 mph, wind gust: out of the WNW to 16 mph, humidity 40%, dew point 21° (yesterday, the readings were 76% and 32° respectively), current snow level is near 2500', observation time temperature was 41°, and the barometric pressure was 30.10" and rising. |

Mid afternoon weather for 2/26-overcast (Cirrostratus and scattered Altocumulus), temperatures are in the mid 50's-which is still about 7 degrees above normal for this day in February-BP 30.05"R along with light air movement from the SE. WA appears to be in between systems as one is East of the area-MT-while another is approaching the coast. As mentioned yesterday, there were indications of "significant warming" for Friday and most of Saturday due to high pressure establishing itself over WA thereby forcing precipitation North of WA over Vancouver Island and Southern BC. In addition, there should be a "big shift of the storm track to the North" by the end of the work week which would create the possibility for
temperatures to reach "60 degrees in the Seattle area". Current conditions for 2/27-mostly clear (scattered Cirrus and Cumulus), no precipitation in the last 24, the haze is light to moderate with little or no air movement. It is from the East at 2 mph, wind puff: out of the ESE to 7 mph, humidity 69%, dew point 27° {yesterday, the readings were 40% and 21° respectively}, current snow level is near 2500', observation time temperature was 25°, and the barometric pressure 30.08" and rising. |

Mid afternoon weather for 2/27-partly to mostly cloudy (scattered Cirrus, Cirrostratus, Altocumulus-some of which were almond shaped-and Cumulus), temperatures are in the mid 50's, BP 30.07"R along with light air movement from basically two directions the South and SE. Current conditions for 2/28-overcast and raining along with little or no air movement. It is from the North at 1-3 mph, wind gust: also out of the North to 11 mph, humidity 92%, dew point 37° {yesterday, the readings were 69% and 27° respectively}, current snow level is near 4500' [yesterday, it was near 2500'], observation time temperature was 37°, and the barometric pressure 30.12" and rising. |

The total precipitation shown above was recorded yesterday at the time indicated below. Mid afternoon weather for 2/28-overcast (Altostratus, scattered Cumulus and fog that obscured the higher ridges and mountains around the valley from view), temperatures are in the low 40's, BP 30.29"R along with light air movement mainly from the North but occasionally from the NE. As both today and tonight should be mild, the snow level will also reflect the mildness at this time of year with a maximum level near 6000' and 7500' respectively. Meanwhile, high pressure over the area (WA) along with a SW flow, should remain through tomorrow before the next trough makes its presence known by sometime Sunday. As a result of the SW flow however, it appears that the bulk of precipitation will be over Vancouver Island and Southern BC instead of NW WA. Current conditions for 3/01-partly cloudy (scattered Cirrus, Cirrostratus, Altocumulus and Cumulus), no precipitation in the last 24, the haze is moderate with little or no air movement. It is from the West at 1-4 mph, wind puff: out of the WSW to 6 mph, humidity 88%, dew point 38°, current snow level is near 5500' [yesterday, it was near 4500'], observation time temperature was 33°, and the barometric pressure 30.27" and rising. |

Mid afternoon weather for 3/02-mostly cloudy (scattered Cirrus, Cirrostratus, Altocumulus-some of which were, once again, almond shaped-and Cumulus), temperatures were in the mid to upper 50's-or about 5 to 7 degrees above normal for this day in March-along with light air movement from the South and occasionally the SW. Current conditions for 3/03-mostly clear (except for some widely scattered Cumulus), no precipitation in the last 24, light to moderate haze along with a nice breeze from the NW. It is from the West at 8-9 mph, wind gust: out of the WNW to 20 mph, humidity 38%, dew point 21°, current snow level is near 1500', observation time temperature was 33°, and the barometric pressure 30.07" and falling. Here are some interesting stats for FEBRUARY- 1) total precipitation: 0.21" or 22% of average and a deficit of 1.69" for JAN and FEB, 2) number of days with no precipitation: 24, 3) high BP: 30.39" on 2/05, 4) low BP: 29.64" on 2/19, 5) date with low BP and no precipitation: 29.64" on 2/19, 6) date with high BP and precipitation: 30.32" on 2/02 (T), 7) average BP: 30.00", 8) average morning temperature- a) digital: 35.7°, b) official minimum: 30.2°, c) normal low: 26.8°, 9) low morning temperature- a) official minimum: 24° on 2/10, 10) high morning temperature- a) official maximum: 41° on 2/26, 11) average afternoon temperature- a) official maximum: 47.3°, b) normal high: 49.8°, c) digital: 51.1°, 12) low afternoon temperature- a) official minimum: 35° on 2/03, and 13) high afternoon temperature- a) official maximum: 58° on 2/13. |

Mid afternoon weather for 3/03-mostly clear (except for widely scattered Cumulus), temperatures were in the low 50's, BP 30.10"R along with a moderately strong breeze from the NW, West and occasionally the South though with less intensity. As a result of yesterday's cold front passing over this area, temperatures this morning were about 7 degrees cooler. Even though the remainder of today should remain dry, indications are that by late tomorrow into Wednesday, there is a likelihood of snow in the valley. However, "accumulations will be highly dependent on warm/cold surface temperatures. If "temperatures remain cool", then obviously "more significant accumulations will be possible". This event is believed to be the result of a large, slow moving low pressure "setting up off the coast of WA" along with a cold front tracking basically East toward WA and OR. Current conditions for 3/04-mostly cloudy (Cirrus, Cirrostratus, an immense halo! and scattered Cumulus), no precipitation in the last 24, light to moderate haze with little or no air movement. It is from the WNW at 4 mph, wind gust: out of the NW to 12 mph, humidity 64% (yesterday, the reading was 38%), dew point 23°, current snow level is near 3500' [yesterday, it was near 1500'], observation time temperature was 26°, and the barometric pressure was 30.28" and rising.

The total amount of precipitation from today's storm will be reported tomorrow (3/07/13). Mid afternoon weather for 3/05-overcast and snowing lightly on or near Birch Mountain to the North, temperatures are in the mid 40's-which is now about 5 degrees BELOW normal for this day in March!-BP 29.97"F along with light air movement mainly from the South though occasionally the East. Though the trough-since yesterday-(with the large, slow moving low pressure now centered off the southern OR coast) moved inland over northern CA, most of OR and WA, it appears that the "weather" is presently coming from the South before turning NW toward Vancouver Island. At this time, it is fairly obvious that precipitation above 3000' will be in the form of snow, while below this level, a snow/rain mix or just rain should be the norm. As a case in point, one model shows a large band of precipitation moving East by NE over NW OR and a rather large pocket of moderate precipitation "surrounding" the Hillsboro area (except for the SE side) while another relatively large band of precipitation extends from Seattle to Everett before turning NW over SE Vancouver Island and Western Whatcom county. Current conditions for 3/06-overcast with a steady rain. The wind is out of the North at 2 mph, then from the WNW at 3 mph, wind puff: out of the NW to 5 mph, humidity 94%, dew point 34° {yesterday, the readings were 50% and 25° respectively}, current snow level is near 2500', observation time temperature was 32°, and the barometric pressure 29.71" and falling. |

Mid afternoon weather for 3/06-overcast and raining lightly. Temperatures are in the upper 30's to low 40's (or about 10-12 degrees BELOW normal for this day in March), BP 29.65"F along with light air movement from the North. Today should remain somewhat "unsettled" while to the East of the area (WA) one model is showing a cold front-along with very cold Canadian air-pushing South over and toward the Northern Plain states-MT and the Dakotas-though its "western" side is tracking SW toward ID and WA. Meanwhile looking ahead to the weekend, yesterday's trough that moved inland (with the large, slow moving low pressure centered off the Southern coast of OR, is now off the Northern coast of CA-near the Bay area) over northern CA as well as most of OR and WA {which brought ample moisture to this area} should be East of WA and considerably "deeper" as the south westernmost boundary will be over central Baja, CA and NW Mexico. As a result dry conditions should prevail through the weekend before turning "wetter" early next week. Current conditions for 3/07-mostly clear (scattered Altocumulus, Cumulus and widely scattered Cirrus), no precipitation during the overnight, the haze is light to moderate with little or no air movement. It is from the East at 2-3 mph, wind puff: out of the East to 5 mph, humidity 91%, dew point 38°, current snow level is near 2500', observation time temperature was 33°, and the barometric pressure was 29.94" and rising. |

Mid afternoon weather for 3/07-while there is partial clearing to the East (scattered Altocumulus and Cumulus Congestus), the West to the SW is a horse of a different color as it is ominous in appearance and snowing lightly. Temperatures are in the low to mid 50's, BP 29.99"R along with light air movement from the West though occasionally from the South. A ridge of high pressure-centered SW and West of Vancouver and WA respectively-should "build" across the Northwest today and remain over the area through most of the weekend which will result in warmer and drier conditions during the period before breaking down and flattening by some time Sunday. As a result, a system will bring precipitation to the area (WA). However, from mid to late next week, there are indications of a pattern change-as the flow switches to southwesterly-and because of this flow direction-or "pineapple express"-sets up a possibility for "potentially heavy rain, at times, for NW WA while Western WA remains dry". Current conditions for 3/08-clear skies (except for widely scattered Cumulus), no precipitation in the last 24, light to moderate haze with little or no air movement. It is from the West at 1-3 mph, wind gust: out of the WNW to 10 mph, humidity 72% {yesterday, the reading was 91%}, dew point 34°, current snow is near 4500' [yesterday, it was near 2500'], observation time temperature was 29°, and the barometric pressure 30.07" and rising. |

Although weak high pressure is currently just West of the WA/OR coasts, with a prospect for mild temperatures and "steady rain-early this week-where 1-2 inches are expected in the Seattle area and 3-5" along the coast", this same high pressure should move over the area (WA) by sometime tomorrow-along with a southwesterly flow-strengthen in the process, and remain through the end of the work week before it begins to breakdown. In addition, low pressure in the Gulf-West of the Alexander Archipelago-will attempt to slide SE toward the Queen Charlottes but should weaken rapidly as it encounters, by then, a moderately strong ridge of high pressure. Current conditions for 3/11-mostly cloudy (scattered Cirrus and Altocumulus), no precipitation in the last 24, the haze is moderate with little or no air movement. It is from the WNW at 2-3 mph, wind gust: out of the NW to 21 mph, humidity 66%, dew point 28°, current snow level is near 4500', observation time temperature was 36°, and the barometric pressure 30.30" and falling. |

The snow level should remain above pass level (6500'-7000') for another two days before a gradual decline commences and continues through the weekend at which time the minimum level will reach only 3000'. The high snow level and mild temperatures are in part a result of low pressure over the Gulf and high pressure centered West of the central coast of Baja, CA which, in turn, establishes a southwesterly flow pattern that should produce abundant rainfall in the "Northern Cascades and Olympics where 4-7" are expected". Elsewhere in the "Cascades and the lowlands of Western WA", much lighter amounts are expected. However, the UW model shows a large band of precipitation moving East over Aberdeen and most of the Olympic Peninsula before turning NE over SE Vancouver Island and NW WA (western Whatcom and Skagit counties). In addition, two relatively large pockets of moderate precipitation are SW and NW of Port Angeles. Looking ahead to the end of the work week as well as Saturday, showers can be expected from SW OR (Eugene) to Seattle with snow in the higher elevations as colder air moves into the area by sometime Sunday. Current conditions for 3/12-partly cloudy {scattered Cirrus, Cirrostratus, Altocumulus and Cumulus}, no precipitation in the last 24, and moderate haze with little or no air movement. It is from the WNW at 0-4 mph, then from the North at 2 mph, wind gust: out of the NW to 12 mph, then out of the NNE to 11 mph, humidity 73%, dew point 34°, current snow level is near 6500' [yesterday, it was near 4500'], observation time temperature was 38°, and the barometric pressure 30.09" and falling.

Mid afternoon weather for 3/12-partly cloudy (scattered Cirrus, Cirrostratus, Altocumulus, and Cumulus), temperatures are in the mid 60's-which is about 14 to 15 degrees above normal and very close to a record high for this day in March-BP 29.97F along with some nice air movement from the NW. With low pressure centered just West of the Alexander Archipelago, and high pressure centered West of Northern Baja, CA (close to the border of Southern CA) along with a moderately strong ridge of high pressure-which should strengthen the next few days according to the GFS and NAM models-thereby assures a southwesterly flow. As a result, this "pineapple express" should continue to bring precipitation to Western WA as well as the coastal area where, in the last 24 hours, Hoquiam received 1.31" while Forks checked in with 5.47"! However, by the weekend, high pressure over the area (WA) for the past several days will have broken down and moved well to the NE thereby allowing showers over Western WA and OR. In the meantime, above normal temperatures-both minimum and maximum-should prevail at least through the end of the work week before colder air moves into the area by sometime Sunday. Current conditions for 3/13-mostly cloudy (scattered Cirrus, Cirrostratus, and Altocumulus), no precipitation in the last 24, and light to moderate haze with little or no air movement. It is from the WNW at 3 mph, wind gust: out of the NW to 12 mph, humidity 74%, dew point 39°, current snow level is near 6500', observation time temperature was 41°, and the barometric pressure was 30.06" and falling. |

Mid afternoon weather for 3/13-overcast-except for partial clearing to the North-(thick Altostratus and scattered Cumulus), temperatures are in the low 60's-which is still well above average for this day in March-BP 30.10"R along with light air movement from the SE. High pressure has indeed strengthened since yesterday and should remain over the area (WA) for one more day before it begins to break down. Meanwhile, precipitation in western WA, including the coastal areas, should not be a "steady stream of moisture" like the past few days because the "conveyor belt" of moisture (pineapple express) is now taking aim at Southern BC and Vancouver Island-where heavy rain is expected today. In addition, although a large bubble of Arctic air has pushed South over the northern and southern provinces of BC and Alberta respectively, it appears that it will not affect this area as much as from the upper mid West Eastward. Current conditions for 3/14-overcast (thick Altostratus and scattered Cumulus), no precipitation in the last 24, light to moderate haze with little or no air movement. It is from the North at 1-2 mph, wind gust: also from the North to 11 mph, humidity 86%, dew point 43° {yesterday, the readings were 74% and 39° respectively}, current snow level is near 6000', observation time temperature was 43°-which is about 12 degrees above normal-, and the barometric pressure 30.03" and rising. |

Mid afternoon weather for 3/14-partly cloudy (scattered Cirrus, Cirrostratus, Altocumulus, and Cumulus), temperatures are in he low to mid 60's-or, about 7-10 degrees above normal-BP 29.94"F along with very light air movement from the South. Current conditions for 3/15-partly cloudy (scattered Cirrus, Cirrostratus and Cumulus), no precipitation in the last 24, and light to moderate haze with little or no air movement. It is from the WNW at 2-3 mph, wind gust: out of the NW to 12 mph, humidity 66% (yesterday, the reading was 86%), dew point 39°, current snow level 5000' [yesterday, it was near 6000'], observation time temperature was 36°, and the barometric pressure 30.06" and rising. |

The amount shown above was recorded yesterday at the times indicated below. Mid afternoon weather for 3/15-overcast (Cirrostratus and Cumulus) with brief intermittent showers. Temperatures are in the mid 60's-which is 10-12 degrees above normal and close another record high-BP 30.07"R along with a nice breeze from the NW. Current conditions for 3/16-partly sunny (scattered Cirrus, Cirrostratus and Cumulus), moderate haze, no precipitation in the last 24, and little to no air movement-for the time being. It is from the West at 1-2 mph, wind gust: out of the WNW to 16 mph, humidity 79% {yesterday, the reading was 66%}, dew point 38°, current snow level is near 4000', observation time temperature was 36°, and the barometric pressure 29.97" and falling. |

The amount shown above was recorded during the overnight. Mid afternoon weather for 3/16-mostly cloudy (Cirrus and Cumulus) and very ominous from the West to the SW where it is snowing on or near Mission Ridge to the SW. Temperatures are in the low to mid 60's, BP 29.77"F along with a nice breeze from the West. Current conditions for 3/17-partly cloudy (scattered Cumulus), fresh snow was observed not only on the higher ridges and peaks, but also on the lower foothills around the valley, the haze is light even though there is nice air movement. It is from the North at 5 mph (although the velocity has picked up since earlier this morning), wind gust: out of the NNW to 19 mph, humidity 54%, dew point 27° {yesterday, the readings were 79% and 38° respectively}, current snow level is near 1500' [yesterday, it was near 4000'], observation time temperature was 35°, and the barometric pressure 29.88" and falling. |

Mid afternoon weather for 3/17-partly cloudy (scattered Cumulus), temperatures are in the upper 40's to low 50's, BP 30.01"F along with a nice breeze from the NW. With the flow pattern from the Northwest over WA, high pressure off the coast of OR and low pressure over Southern BC-near the BC/Alberta border-may very well be the factors contributing to the windy conditions at the observation site. Meanwhile, by tomorrow into Wednesday, in addition to "soaking rains"-where as much as an inch is possible in "some neighborhoods" in Western WA and ample mountain snow-a strong cold front will push through the area with the likelihood of generating moderately strong winds and gusts from 35-50 mph before "winding down later in the afternoon" and becoming drier near the end of the work week. Current conditions for 3/18-mostly clear (widely scattered Cumulus) no precipitation in the last 24, the haze is light to moderate along with a nice breeze. It is from the West at 7 mph, wind gust: out of the NNW to 19 mph, humidity 52%, dew point 28°, current snow level is near 1500', observation time temperature was 26°, and the barometric pressure 30.03" and rising. |

Mid afternoon weather for 3/18-clear skies (except for widely scattered Cirrus and Cumulus), temperatures are in the low to mid 50's, BP 30.07"R along with a nice breeze mainly from the West and NW though occasionally from the NE. Although high pressure is over the area(WA), a strong low pressure-SW of Vancouver Island and West of WA-will be tracking NE toward Vancouver Island today and bring rain to SE Vancouver Island, Western WA, OR, and NW CA while snow should fall in NW Vancouver Island, the SW coastal range of BC and the Cascades of WA. Behind the "rain", mentioned above, there is a large pool of heavy rain that will affect Western WA where as much as an inch is possible in "some neighborhoods' and ample snow in the Cascades as up to a foot or more is expected at pass levels and up to "2-3 FEET could fall along South and West facing slopes of the volcanoes"! In addition, strong winds (with gusts ranging from 35 to 50 mph) will accompany the storm as a result of a strong cold front pushing through the area-WA-late tonight into tomorrow before winding down tomorrow afternoon and becoming drier and cool by the end of the work week. Current conditions for 3/19-overcast {Cirrus, Cirrostratus and a large halo!}, no precipitation in the last 24, the haze is moderate with little or no air movement. It is from the WNW at 1-2 mph, wind gust: is out of the NW to 10 mph, humidity 61%, dew point 24°, current snow level is near 4000', observation time temperature was 27°, and the barometric pressure 30.22" and rising. |

The amount recorded above occurred yesterday at the time indicated below. Mid afternoon weather for 3/19-the high thin overcast of earlier this morning thickened to a semi transparent Altostratus at the time of this report. Temperatures are in the upper 40's to low 50's, BP 30.06R along with light air movement mainly from the NW but occasionally from the North. Although today is the first day of spring, another vigorous storm (with one model showing low pressure just West of Vancouver Island)-much like yesterday-will bring heavy rain to the coastal areas of WA and more heavy snow in the Cascade passes (6-12" fell yesterday) where an additional "1-2 FEET is expected through tonight". In addition to the precipitation, there will be strong winds with gusts ranging from 30-55 mph as a result of another strong cold front pushing through the area (WA) today before winding down sometime this afternoon. Current conditions for 3/20-partly sunny (scattered Cumulus and extensive fog), the haze is light to moderate with little or no air movement. It is from the East at 2 mph, wind puff: out of the ESE to 4 mph, humidity 96%, dew point 36° {yesterday, the readings were 61% and 24° respectively}, current snow level is 4000' lowering to 3000' this afternoon, observation time temperature was 33°, and the barometric pressure 29.60" and falling. |

The amount shown was recorded at the time shown below. Mid afternoon weather for 3/20-from mostly overcast with extensive fog earlier this morning, to mostly cloudy (Cumulus) this afternoon, then back to mostly overcast and light rain. Temperatures are in the low to mid 50's, BP 29.54"F with light air movement from the South but occasionally from the SW. Although this area is experiencing "nice weather", the same cannot be said for he passes as another system will move on shore today that should usher in much cooler air (due to a northwesterly flow over WA)-and will be reflected by a much lower snow level than yesterday-as well as rain showers to Western WA/OR but snow to the Cascades (passes) where yet another "winter advisory" has been posted for an additional 6-17" with the "heaviest snowfall occurring this afternoon and evening". Current conditions for 3/21-partly sunny (scattered Cumulus), no precipitation during the overnight, the haze is light to moderate with little or no air movement. It is from the West at 1 mph, wind gust: out of the West to 26 mph, humidity 52%, dew point 26° {yesterday, the readings were 96% and 36° respectively}, current snow level is near 400' rising to 1000' later this afternoon [yesterday it was near 4000' then LOWERED to 3000' sometime yesterday afternoon!], observation time temperature was 30°, and the barometric pressure 29.95" and rising. |

The amount shown was recorded yesterday at the time shown below. Mid afternoon weather for 3/21-partly sunny (scattered Cumulus) with two large cloud decks one of which extends from the NW to the East, where precipitation was observed to the NE, while the other extended from the West to the SE. Temperatures are in the upper 40's to low 50's, BP 30.01"R along with light air movement from the NW. With a northwesterly flow over WA, it should remain cool for at least another day. In the meantime, one model is showing a wave approaching the Queen Charlottes and Vancouver island coastline while the "clouds" cresting the ridge of high pressure-centered over the Pacific and West of Northern CA-appear to be approaching SW OR and Northern CA. Looking ahead to early next week, it looks as though this area (WA) will finally get a break from the several systems that moved through the area (WA) and brought rain, snow-to the Cascades and even the lowlands of Western WA-and much cooler air due to a northwesterly flow. This "break" should give the temperatures a chance to rebound before the next round of wet weather arrives by sometime early next week. Current conditions for 3/22-partly sunny (scattered Cirrus, Cirrostratus and Altostratus), no precipitation in the last 24, light to moderate haze with some light air movement. It is from the WNW at 3-5 mph, wind gust: out of the NW to 15 mph, humidity 47%, dew point 23°, current snow level is 500', observation time temperature was 32°, and the barometric pressure 30.11" and rising. |

Mid afternoon weather for 3/22-mostly cloudy (some scattered Cumulus and one very large cloud deck) and very unstable. Brief showers were observed toward the East and NE on or near Badger Mountain to the East and Burch Mountain to the North as well as virga toward the North. Temperatures are in the upper 40's to low 50's, BP 30.16"R along with light air movement from the NE. Although it is overcast in this area-high thin clouds-today should stay dry (as high pressure over the Pacific-just West of the WA, OR, and Northern CA coasts-is close enough to be influential) and cool due to a persistent northwesterly flow. Its stay-the high pressure just mentioned-however will be brief as it will begin to break down by sometime tomorrow and wet weather returns to the coastal areas of WA and OR by early next week. Current conditions for 3/23-partly sunny (Cirrus, Cirrostratus, Altocumulus, Cumulus and two large sun dogs!), no precipitation in the last 24, and moderate haze with little or no air movement. It is from the WNW at 4 mph, wind gust: out of the NW to 13 mph, humidity 51%, dew point 21°, snow level is near 2500' [ yesterday, it was near 500'], observation time temperature was 28°, and the barometric pressure 30.35" and rising. |

Mid afternoon weather for 3/23-mostly clear (scattered Cumulus and what appears to be a large area of dense Cirrus clouds to the North and SW), on an otherwise very pleasant spring afternoon. Temperatures are in the low 50's, BP 30.25"R along with light air movement from two directions including the South and North. Although a weak ridge of high pressure should remain over WA through early next week, an area of low pressure (centered just West of the Queen Charlottes along with a warm front moving East by NE over the southern portion of the Queen Charlottes and Vancouver Island but just "nicking" NW WA-Olympic Peninsula-as well as a cold front tracking East by NE-though currently well West of any land mass) should bring light rain to the coastal areas of WA-the Olympic Peninsula in particular-before quickly dissipating. Interestingly, these "systems will come close but not close enough to generate any rainfall" as far as the interior of Western WA is concerned. Looking ahead, there are indications that the early part of this week will be dry as "temperatures should begin to warm" before a chance of precipitation develops by midweek (at which time temperatures should reach "above normal") although no "major storms are expected". Current conditions for 3/24-mostly sunny (scattered Cirrus, Cirrostratus and Cumulus), no precipitation in the last 24, light frost was observed on the yard earlier this morning, and moderate haze with little or no air movement. It is from the WNW at 2-5 mph, wind gust: out of the NW to 12 mph, humidity 66% (yesterday, the reading was 51%), dew point 24°, current snow level is near 4000' [ yesterday, it was near 2500'], observation time temperature was 24°, and the barometric pressure 30.033" and rising. |

Mid afternoon weather for 3/24-mostly clear (scattered Cirrus, Cirrostratus and Cumulus), temperatures are in the mid 50's, BP 30.17"R along with light air movement from the South. Today will feature mild temperatures across much of WA and OR even though a low pressure system is just West of the WA coast bringing light rain showers-or drizzle-to most of Vancouver Island as well as the central and SW coasts of BC. However, as was noted yesterday, these "systems will come close but not close enough to generate any rainfall" as far as the interior of Western WA is concerned. Meanwhile, looking ahead to the weekend, there are indications that high pressure will begin to build in over (WA) and remain through at least the weekend resulting in dry conditions and possibly above normal temperatures. A clue to this "possibility" is reflected by the freezing level rising abruptly to 7500' by Friday night and reaching a maximum level of 9500' through the weekend. Current conditions for 3/25-mostly clear (scattered Cirrus, Cirrostratus and a large halo!), light frost was observed earlier this morning, no precipitation in the last 24, the haze is light to moderate with little or no air movement. It is from the North at 3-5 mph, wind puff: out of the NNW to 9 mph, humidity 61%, dew point 23°, current snow level is near 5000' [yesterday, it was near 4000'], observation time temperature was 24°, and the barometric pressure 30.18" and rising. |

Mid afternoon weather for 3/25-mostly clear (scattered Cirrus and Cirrostratus), temperatures are in the upper 50's to low 60's, BP 30.00"F along with light air movement mainly from three directions that included the East, SE, and South as well a splendid view of Glacier Peak! Not much change from yesterday as today will also feature mild temperatures across much of WA and OR with weak high pressure currently in place over WA. The only glitch to these "pleasant" conditions is a weak disturbance (just off the coast of Vancouver Island) that should bring scattered showers over much of Vancouver Island and the "Portland area south toward Eugene" where one model is showing two bands of precipitation tracking North by NE over NW OR while another band is moving North-off the coast of WA-with a remnant over the NW portion of the Olympic Peninsula. Looking ahead toward the end of the week, the current dry conditions will continue to prevail along with sunshine and above normal temperatures as high pressure builds over (WA) by sometime Friday and remain through early next week at which time it will gradually begin to break down and move East of the area(WA). Current conditions for 3/26-mostly clear (except for some widely scattered Cirrus and Altocumulus), no precipitation in the past 24, the haze is moderate with little or no air movement. It is from the WNW at 2-3 mph, wind gust: out of the NW to 14 mph, humidity 71% {yesterday, the reading was 61%}, dew point 27°, current snow level is near 5000', observation time temperature was 26°, and the barometric pressure 30.02" and falling. |

Mid afternoon weather for 3/26-mostly sunny (scattered Cirrus, a small area of Altocumulus to the NW and widely scattered Cumulus), temperatures are in the low to mid 60's, BP 29.91"F along with calm winds. Not much change since yesterday as temperatures should continue to be on the mild side across much of WA and OR today. The only fly in the ointment is a weak low pressure-West of the WA/OR coasts-that should bring showers to Vancouver Island, the coastal areas of WA and OR as well as some snow to the Cascades of WA "above 5000'". Looking ahead-the Easter weekend is shaping up to be "fantastic" as the present dry conditions should continue to prevail along with sunshine and above normal temperatures-mid to upper 60's and possibly the low 70's-due to high pressure building over the area by sometime Friday and remaining through early next week at which time it will gradually begin to break down and move East of the area (WA). Current conditions for 3/27-mostly overcast (Altocumulus), no precipitation in the past 24, the haze is moderate to bad with little or no air movement. It is from the WNW at 4 mph, wind puff: out of the NW to 12 mph, humidity 65%, dew point 35° {yesterday, the reading was 27°}, current snow level is near 5000', observation time temperature was 41°, and the barometric pressure 29.94" and falling. |

Mid afternoon weather for 3/27-overcast-except for some partial clearing from the South to the SE-with brief intermittent sprinkles. Temperatures are in the upper 50's to low 60's, BP 29.95"F along with light air movement mainly from three directions including the East, South, and SW. Though dry conditions should continue in Eastern WA today, Western WA will be the recipient of "spotty showers" from the "I5 corridor West toward the coast" due to weak low pressure off the NW coast of OR. Meanwhile, the anticipation of a "fantastic" Easter weekend will come to fruition with sunshine and above normal temperatures (mid to upper 60's with the possibility of nudging the low 70's!)as high pressure builds over WA by sometime tomorrow and should remain through early next week at which time it will gradually begin to break down and move East of the area (WA). Current conditions for 3/28-partly sunny (Cirrus, Cirrostratus, scattered Cumulus and a partial halo!), no precipitation in the past 24, the haze is moderate to bad with little or no air movement. It is from the North at 1-3 mph, wind gust: out of the NNW to 14 mph, humidity 79% {yesterday, the reading was 65%}, dew point 36°, current snow level is near 5500', observation time temperature was 36°, and the barometric pressure 30.03" and rising. |

Mid afternoon weather for 4/01-clear skies (except for some widely scattered Cirrus and Cumulus), temperatures are in the upper 70's to low 80's (which may have tied the record high in this area-80°-and is about 20 degrees above normal for this first day of April), BP 29.86"F along with light air movement from the West on this summer like spring afternoon. Slightly cooler today than yesterday? Although today should remain pleasant, one model is showing "cooler" conditions-tonight into tomorrow-for Western WA (Seattle area toward the coast) due in part to a cold front tracking South by SE over NW Vancouver Island and Southern BC toward WA as well as cooler air from off the Pacific. Looking ahead to the latter part of the work week and into the weekend should feature a departure from the dry conditions and warm temperatures that were enjoyed Easter weekend and the first part of this work week to one of cool, wet weather as low pressure off the NW coast of OR (tracking NE toward Vancouver Island) will bring rain to Vancouver Island, WA most of OR and Northern CA while the snow level will gradually lower from 6000' today to near 3000' by sometime Saturday evening and Sunday. Current conditions for 4/02-clear skies-except for scattered Cirrus-no precipitation in the last 24, the haze is light to moderate along with light air movement. It is from the NW at 4-6 mph, wind gust: out of the NW to 17 mph, humidity 44% {yesterday, the reading was 61%}, dew point 38°, current snow level is near 6000' [yesterday, it was near 7500'], observation time temperature was 52° and the barometric pressure 30.03" and falling. |

Mid afternoon weather for 4/02-mostly clear (scattered Cirrus, Cirrostratus, numerous lenticular clouds and Cumulus), temperatures are in the low to mid 70's-somewhat cooler than yesterday!-BP 29.96"R along with some nice air movement mainly from the North. Not much change from yesterday-except for the possibility of slightly cooler temperatures. This should be the last day of pleasant weather (because of weak high pressure over WA) before a "series of storms" move into the NW with the first "scheduled" to arrive sometime "tomorrow afternoon" followed quickly by a second storm which should arrive sometime "Friday evening". Looking ahead, it was noted yesterday that the upcoming weekend will feature a relative sharp departure from the dry conditions and warm temperatures enjoyed from Easter weekend through mid week to one of "cool and unsettled" wet weather as low pressure (West of Northern CA near the OR border) should bring rain to the coastal area of WA and OR, "showers further inland", and the possibility of snow in the mountains-Cascades- as the snow level will gradually lower from 7000' today to near 3000' by the weekend. Current conditions for 4/03-mostly clear (widely scattered Cirrus), no precipitation in the past 24, the haze is moderate with little or no air movement. It is from the WNW at 2-3 mph, wind gust: out of the NW to 20 mph, humidity 51%, dew point 37°, current snow level is near 7000' {yesterday, it was near 6000'}, observation time temperature was 47°, and the barometric pressure 30.06" and rising. |

Mid afternoon weather for 4/03-partly cloudy (scattered Cirrus, Cirrostratus, Cumulus, and a large deck of Altostratus moving from West toward the East), temperatures are in the low to mid 70's, BP 29.96"R along with light air movement mainly from the SW. Cool and unsettled weather will be the norm today through the weekend with the first in a series of storms arriving sometime this afternoon bringing heavy rain to SW BC, Vancouver Island, the coastal area of WA ("where 1-2" are expected at the coast, and a half to one and a half inches for the interior lowlands" as well as wind from the South to SW at 15-30 mph with gusts around 40 mph), OR and Northern CA. East of the Cascades should also benefit from this storm (though with less intensity than "Western WA") in the form of showers. As for the weekend, little if any change from yesterday's outlook with the second storm-in a series-arriving sometime tomorrow evening along with a possibility of snow in the Cascades because the snow level will gradually lower from 6000' today to 3000' by Saturday and Sunday as a result of a cold front associated with low pressure just West of Vancouver Island. Current conditions for 4/04-overcast and raining. Air movement is from the North at 2-3 mph, wind gust: out of the NNW to 13 mph, humidity 61% (yesterday, the reading was 51%), dew point 40°, current snow level is near 7000', observation time temperature was 50°, and the barometric pressure 29.88" and falling. |

The amount shown was recorded yesterday at the time shown below. Mid afternoon weather for 4/04-overcast and raining-for most of the day!-temperatures are in the low to mid 50's (or about 20 degrees cooler than yesterday), BP 29.73"F along with calm winds. Yesterday's storm that brought ample rainfall to this area, has moved NE over Southern BC and should begin to weaken sometime tomorrow. With its passage, there will be a short break before the next storm arrives sometime this evening or "early tomorrow" and bringing with it "strong heavy rain and gusty winds" to the coastal areas of WA. Behind the front, it will be breezy due to a cold front tracking East by NE over the area just mentioned. However, by early next week, a very deep trough will "set up" (with the southernmost boundary over the northern Baja peninsula) thereby insuring the continuation of cool and unsettled weather with rain in the coastal areas of WA and snow in the Cascades as the strongest system in the series moves over northern OR and SW WA resulting in "heavy rain and strong winds to those areas". Current conditions for 4/05-mostly cloudy (Cirrus, Cirrostratus and Cumulus-the dominant variety), the haze is light to moderate with little or no air movement. It is from the WNW at 4-5 mph, wind puff: out of the NW to 8 mph, humidity 84%, dew point 48° {yesterday, the readings were 61% and 40° respectively}, current snow level is near 5500' [yesterday, it was near 7000'], observation time temperature was 46°, and the barometric pressure 29.74" and falling. |

The amount shown was recorded during the early hours of this morning. Mid afternoon weather for 4/04-increasing cloudiness since earlier this morning (scattered Cirrus, Cirrostratus, Cumulus, and a very large deck of Altostratus moving from West toward the East), temperatures are in the mid to upper 60's, BP 29.79"F along with light air movement from the NE. The storm that brought measurable precipitation to this area has since moved East over the eastern third of WA. In the meantime, cooler and unsettled weather should continue for what is believed to be two reasons with the first being a cold front tracking East by SE across WA, and more wet weather is on the way with the next system moving East by NE toward NW OR and WA (although one model is showing numerous "small" bands of precipitation moving NE over NW OR, SW and Western WA including the SE side of the Olympic Peninsula and the Sedro Woolley/Mt. Vernon region). By early next week however, a deep trough should "set up" with the southern most boundary over the Northern Baja peninsula thereby insuring the continuation of cool and unsettled weather with rain in the coastal area of WA and snow in Cascades as the strongest system in the series moves over Northern OR and SW WA resulting in strong, heavy rain and gusty winds to the areas just mentioned. Current conditions for 4/06-mostly cloudy (Cirrus, Cirrostratus, Cumulus-and very ominous to the North, NW and SW where rain was observed), the haze is light to moderate along with some nice air movement. It is from the WNW at 5-6 mph, wind gust: out of the NW to 27 mph, humidity 74% {yesterday, the reading was 84%}, dew point 43°, current snow level is near 4000' [yesterday, it was near 5500'], observation time temperature was 44°, and the barometric pressure 29.76" and falling. |

Mid afternoon weather for 4/06-partly sunny (scattered Cirrus, Cirrostratus, and Cumulus), temperatures are in the low to mid 60's, BP 29.83"F along with light air movement mainly from the West and SW. The cool and unsettled weather of the past few days will continue for another day with gusty winds, heavier rain for most of Vancouver Island, Western WA, OR {where one model is showing numerous "small" bands of precipitation moving East by NE over NW OR and SW WA while further North the coastal area of WA is getting "pounded" by a larger band with numerous areas of moderate precipitation within it. Not to be outdone, a very large band extends SE to NW from the Auburn area to Western Whatcom county along with moderate precipitation from North Marville to NW of Burlington} and Northern CA as well as snow in the Cascades where an additional 6-10" are expected. What also has been noted for the past few days is the development of a relatively deep trough with the southern most boundary over Southern CA-near the Baja Peninsula border. However, with this development, there are indications that by early this week, high pressure will begin to build over the area (WA) and remain through mid week before it begins to break down and weaken in the process. Current conditions for 4/07-mostly cloudy (Cirrus, Cirrostratus, Altostratus, Cumulus and patchy fog), snow fell on the higher ridges and peaks around the valley, the haze is light along with some nice air movement. It is from the West at 6-10 mph, wind gust: out of the WNW to 17 mph, humidity 92%, (yesterday, the reading was 74%), dew point 38°, current snow level is near 3000', observation time temperature was 38°, and the barometric pressure 29.58" and falling.

Mid afternoon weather for 4/07-overcast(except for some partial clearing to the NW), temperatures are in the mid 50's, BP 29.61"F along with light air movement mainly from the North and NW. "Left over spotty showers" should be the main feature today as yesterday's storm moved East over the Northern Rockies. As the day progresses however, these "spotty showers" will diminish as high pressure begins to build over the area (WA) and remain through much of mid week resulting in dry conditions and somewhat warmer temperatures before it begins to quickly break down and simultaneously weaken. In the meantime, {it was noted yesterday that a deep trough would develop-which has indeed occurred-but with the Southern most boundary now over the Northern half of the Baja Peninsula!}, there are indications of a return to cool and unsettled "weather"-similar to this past weekend-by the end of the work week due, in part, to a NW flow over WA during this period. Current conditions for 4/08-mostly cloudy (scattered Altocumulus and Cumulus), there was light snow on the higher ridges and peaks around the valley this morning, the haze is light with little or no air movement. It is from the West at 0-2 mph, wind gust: out of the West to 14 mph, humidity 74% (yesterday, the reading was 92%), dew point 37°, current snow level is near 3000', observation time temperature was 40°, and the barometric pressure 29.89" and rising. |

Mid afternoon weather for 4/08-overcast with light rain for a brief period, temperatures are in the upper 50's to low 60's, BP 30.03"R along with light air movement from the NE. Although most of the "energy" is moving SW to NE over the Queen Charlottes, most of BC, and Vancouver Island with some of this "energy" extending south over the coastal area of WA, today should feature dry conditions and warmer temperatures than the past several days as high pressure over the area (WA) will remain through most of tomorrow before it begins to quickly break down and simultaneously weaken thereby opening the door, once again, to a return of "cool and unsettled" weather by the end of the work week through the weekend due, in part, to a cold front early Saturday. As a result, the weekend is basically going to be "unsettled and chilly"-as the minimum freezing level will hover between 2000'-3000'-with the likelihood of rain in the lowlands and snow in the higher elevations. Current conditions for 4/09-mostly overcast (Altocumulus and widely scattered Cumulus), no precipitation in the past 24, the haze is light to moderate with little or no air movement. It is from the WNW to 3 mph, wind gust: out of the NW to 10 mph, humidity 68%, dew point 34°, current snow level is near 5000', observation time temperature was 35°, and the barometric pressure 30.27" and rising. |

Mid afternoon weather for 4/09-partly sunny (a Cirrostratus overcast, scattered Altocumulus, and widely scattered Cumulus), temperatures are in the upper 50's to low 60's, BP 30.18"R along with slight air movement from the East. A return to cool and unsettled weather appears to be underway as high pressure over (WA) for the past few days should quickly break down and simultaneously weaken. Though low pressure over Southern BC should bring rain along with "increasing wind" to Western WA, "heavy rain is expected for the coastal areas where up to an inch is expected". In the meantime, as far as this area is concerned, a "strong and wet cold front will move over the region today" generating rain this morning but will taper off as "strong winds develop this afternoon and continue through this evening due to a cold front passing through the area". This event will be followed by yet another storm sometime Saturday with similar results mentioned above. Behind this system however, much colder air will move in over WA during the weekend and will be especially noticed at pass level where the minimum freezing level will be hovering between 2000'-3000'. Current conditions for 4/10-overcast (thick Altostratus and scattered Cumulus), a light rain stopped a few minutes ago, the haze is light to moderate along with some air movement. It is from the ESE at 4-6 mph, wind gust: out of the SE to 11 mph, humidity 77%, dew point 40°, current snow level is 7500' lowering to 5500' later this afternoon, observation time temperature was 44°, and the barometric pressure 30.01" and falling. |

Mid afternoon weather for 4/10-partly cloudy (scattered Cumulus), temperatures are in the low to mid 60's, BP 29.85"F along with a nice breeze from the NW. Yesterday's strong and wet cold front that brought light rain amounts-to this area anyway-and breezy winds {which continued through last evening} due to a cold front passing through the area, has moved East and in its place high pressure-off the WA/OR coast-has begun to build over the PNW although its stay looks to be short lived. Looking ahead-the weekend should be unsettled and down right cold! as the NPJ drops south of WA in a NW flow over OR. This sets up the likelihood of rain in the lowlands and snow in the mountains as yet another storm is expected to arrive sometime Saturday. Behind this system however, much colder air will move over WA and should be noticed especially on Sunday through early next week not only in this area, but also at pass level where the minimum freezing level should be hovering between 2000'-2500'. Current conditions for 4/11-mostly cloudy (scattered Cirrus, Cirrostratus, Altostratus and Cumulus), no precipitation in the last 24, and light to moderate haze with some light air movement. It is from the WNW at 1-2 mph, wind gust: out of the NW to 27 mph, humidity 69%, dew point 34°, current snow level is near 3000' [yesterday, it was near 5500'}, observation time temperature was 40°, and the barometric pressure 30.11" and rising. |

Mid afternoon weather for 4/11-mostly clear (scattered Cirrus and Cumulus), temperatures are in the low to mid 60's, BP 30.09"R along with some nice air movement mainly from the NW. Although at the present time it was partly cloudy to overcast in Western WA, today through the weekend will continue to be unsettled and cool at least for Western WA as yet another storm along with a cold front tracking South by SE over WA is expected to arrive sometime today setting up the likelihood of lowland rain, blustery winds, and snow in the mountains where 4-11" are expected as the minimum snow level will hover between 1500'-2500' during this period. Not to be left out, this area will also be unsettled and down right cold-especially from Saturday through early next week-because behind this system {mentioned above}, much colder air will move over WA due to a strong cold front which should set up the likelihood of strong winds tomorrow with maximum gusts reaching 40-50 mph. Current conditions for 4/12-overcast (Altostratus duplicatus), no precipitation in the last 24, the haze is light to moderate with little or no air movement. It is from the WNW at 3-4 mph, wind gust: out of the NW to 14 mph, humidity 59%, dew point 30°, current snow level is near 3000', observation time temperature was 34°, and the barometric pressure 30.07" and rising. |

The amount shown above was recorded in the following increments: 0.02" last evening and 0.10" this morning. Mid afternoon weather for 4/14-overcast (except for partial clearing to the West and SE), with a light rain of brief duration, and what appears to be either rain or a snow/rain mix on Burch Mountain to the North. Temperatures are in the mid 50's, BP 29.86"F along with nice air movement from the North on a rather cool spring afternoon. This area anyway, should endure one more day of cool and unsettled weather with showers in the lowlands and snow in the mountains as cold Canadian air has moved South over most of the PNW. Looking ahead however, pleasant weather will finally return and be the dominant feature at least from tomorrow through Thursday-if not longer-as high pressure begins to build over WA and remain through early next week at which time it should strengthen even more according to both the GFS and NAM models. As a result, dry conditions and warmer temperatures should prevail during this period. Current conditions for 4/15-overcast (Altostratus, scattered Cumulus and patchy fog), a fresh mantle of snow fell on the higher ridges and peaks around the valley, the haze is light to moderate with little or no air movement. It is from the SSE at 2 mph, wind puff: out of the SE to 9 mph, humidity 90%, dew point 36° {yesterday, the readings were 54% and 28° respectively}, current snow level is near 2000', observation time temperature was 36°, and the barometric pressure 29.93" and rising. |

Yesterday's total rainfall amounted to 0.15". Mid afternoon weather for 4/15-partly sunny (Cirrus, Cirrostratus, a large deck of Altostratus and Cumulus Congestus near the Eastern horizon), temperatures are in the low 50's, BP 30.02"R along with light air movement from the NW. The cool and unsettled weather of the past several days, may, in fact be coming to an end-although the morning temperatures should remain somewhat cool-as dry conditions and warmer temperatures will finally return and be the dominant feature at least today through Thursday-if not longer-as both the GFS and NAM models continue to show high pressure beginning to build over WA and remaining through early next week. Even though one forecast is calling for "coastal rain and mountain snow" by the end of the work week, and "precipitation moving inland by the following day", it is believed that this ridge of high pressure will be strong enough to block the precipitation although the air flow over WA will be from the NW at some point during this period. Current conditions for 4/16-partly cloudy (scattered Cumulus), the haze is light to moderate with some air movement. It is from the West at 2-5 mph, wind puff: out of WNW to 8 mph, then from the WSW to 9 mph, humidity 79% (yesterday, the reading was 90%), dew point 36°, current snow level is near 4500' [yesterday, it was near 2000'], observation time temperature was 36°, and the barometric pressure 30.24" and rising. |

Mid afternoon weather for 4/16-mostly cloudy (scattered Cumulus), temperatures are in the mid to upper 50's, BP 30.26"R along with nice air movement from both the East and North. With the exception of a "minor disturbance" over SW BC-near the WA border-by sometime Sunday, the GFS and NAM models continue to show high pressure over WA through the end of the work week even though "coastal rain, wind, and mountain snow" are in the forecast for this period at which time, the air flow over WA will be from the NW-in contrast to a more Northerly flow today-along with a strong, high pressure over the Gulf region. Once the "minor disturbance" (mentioned above) quickly passes SE of WA, the ridge of high pressure should quickly rebuild and simultaneously move East over WA and remain through much of next week before it begins to break down and move East as another "disturbance" approaches WA. Current conditions for 4/17-mostly clear (scattered Cirrus and Cumulus), no precipitation in the last 24, the haze is light to moderate with little or no air movement. It is from the SE at 2 mph, then from the North at 2-5 mph, wind gust: out of the WNW to 10 mph, humidity 62%, dew point 29°, (yesterday, the readings were 79% and 36° respectively), current snow level is near 5500' [yesterday, it was near 4500], observation time temperature was 30° {or about ten degrees below normal and very close to a record low for this day in April), and the barometric pressure 30.40" and rising. |

Mid afternoon weather for 4/21-mostly cloudy-though ominous from the South to the SW-where rain, a rain/snow mix or snow was falling on or near Mission Ridge to the SW. Temperatures are in the upper 50's to low 60's, BP 30.07R along with a nice breeze mainly from the North. The cool and unsettled weather-of the past several days-is finally a thing of the past for awhile as the PNW should remain dry and mild through much of the work week with the warmest period occurring from Wednesday through the end of the work week before a return to wet and cooler conditions by the weekend. This pleasant weather is due to a strong ridge of high pressure-at the surface and aloft-over the Eastern Pacific which, at the present time, is deflecting moisture up its West side from HI to the southern boundary of AK and NW BC. Current conditions for 4/22-clear skies, no precipitation in the last 24, the haze is light to moderate with little or no air movement. It is from the North at 2-3 mph, then from the SE at 3 mph, wind gust: out of the NNW to 11 mph, humidity 60%, dew point 31°, current snow level is 4000' rising to 5000' later this afternoon, observation time temperature was 29° [this appears to be a record low; the previous low was 30° on this day in 1949], and the barometric pressure 30.43" and rising. |

Mid afternoon weather for 4/22-clear skies (except for scattered Cirrus from the West to the NW and Cumulus to the SW)), temperatures are in the mid 60's, BP 30.36"R along with some nice air movement from the East and North. Although high level clouds have "invaded" this area (due to a disturbance moving NW to SE-and weakening in the process-over Southern BC and Alberta, NW to SE WA, most of the ID panhandle and NW MT), high pressure continues to build over the Eastern Pacific resulting in continued dry and mild conditions through much of the work week with the warmest temperatures peaking tomorrow before high temperatures commence to back off somewhat for the remainder of the week. However, these pleasant conditions should come to an unhappy end as a disturbance will, unfortunately, bring a return to showers and cooler conditions to Western WA (SEA area) by the weekend. Current conditions for 4/23-overcast (Altostratus) and cool, no precipitation in the last 24, the haze is light to moderate with little or no air movement. It is from the North at 7 mph, the WNW at 6 mph and finally the SW at 4 mph, wind gust: out of the NW to 14 mph, humidity 60%, dew point 29°, current snow level is near 6500' [yesterday, it was near 5000], observation time temperature was 33°, and the barometric pressure 30.30" and falling. |

Mid afternoon weather for 4/23-from mostly overcast (high thin clouds) earlier in the day to mostly clear skies (widely scattered Cumulus). Temperatures are in the mid 60's, BP 30.18"F along with light air movement from the NE. Strong high pressure-centered West of NW OR-is diverting moisture well to the North of WA as well as expanding East over WA and, as a result, dry conditions a warmer temperatures should prevail today and tomorrow with the highs topping off in the upper 60's to low 70's, and possibly the low to mid 70's on Friday. Unfortunately by the weekend, this pleasant weather will seem like a distant memory as a disturbance will bring a return to wet and much cooler conditions by the weekend through early next week. As a case in point, the minimum snow level is projected to be near 2500' by Monday! Current conditions for 4/24-clear skies (except for some widely scattered Cirrus), no precipitation in the last 24, the haze is moderate with little or no air movement. It is from the WNW at 3 mph, then from the SE at 3 mph, wind gust: out of the NW to 14 mph, humidity 55%, dew point 32°, current snow level is near 7500' [yesterday, it was near 6500'], observation time temperature was 33°, and the barometric pressure 30.30" and falling. |

Mid afternoon weather for 4/25-mostly clear (scattered Cirrus and Cumulus) on a beautiful spring afternoon. Temperatures are in the mid to upper 70's-which is about 10-12 degrees above average for this day in April-BP 29.91"F along with some nice air movement from multiple directions including the North, East, SW and West. High pressure over WA the past few days should provide another day of dry conditions and warm temperatures then begin to break down, move East, and simultaneously "flatten" by sometime tomorrow. This should open the door to the first of two systems, which will also arrive sometime tomorrow,-with the second (strongest of the two)projected to arrive Monday-that will usher a return to "wet" (mainly over Western WA) and much cooler conditions from the weekend through early next week. As a case in point, the freezing level will drop from a maximum level of 10,000' today, to a minimum level of 2000' by early next week. WOW! In addition to the "wet" and cooler conditions, both of these systems will generate strong winds with "gusts 35-45 mph-Saturday-and 45-55 mph-Monday. Current conditions for 4/26-mostly sunny (scattered Cirrus and Cirrostratus), no precipitation in the last 24, the haze is moderate with little or no air movement. It is from the West at 4-5 mph, then from the South at 4 mph, wind gust: out of the WNW to 14 mph, humidity 48% {yesterday, the reading was 34%}, dew point 41°, current freezing level is near 10,000', observation time temperature was 51°, and the barometric pressure 30.09" and falling. |

Mid afternoon weather for 4/26-partly sunny (scattered Cirrus, Cirrostratus and Cumulus), temperatures are in the upper 70's to low 80's, BP 30.07"R along with nice air movement from the NW. Once again, high pressure over WA the past several days, should begin to breakdown, move East and simultaneously flatten today thus opening the door to the first-and rather weak-system along with a weak cold front tracking South by SE over Southern BC, the NW tip if Vancouver Island toward WA. This heralds a return to "wet" (mainly over Western WA where one model is currently showing light rain moving East over SE VI and the NW sector of the Olympic Peninsula) and much cooler conditions-with a possibility of "high elevation snow"-commencing tomorrow through early next week. The freezing level is a good barometer of how cool it will get during this period as it will drop from a maximum level of 6500' today, to a minimum level of just 2000' by early next week. In addition, the system will generate "sustained winds of 20-30 mph with gusts 35-45 mph". Following the passage of this system, a second and stronger system should arrive sometime Monday bringing even stronger gusts as "high as 45-55 mph"! WOW! Current conditions for 4/27-partly sunny {scattered Cirrus, Cirrostratus, Cumulus and some Altostratus), no precipitation in the last 24, the haze is light to moderate with little or no air movement-although it has picked up some in the last half hour. It is from the North at 1-4 mph, then the East at 2 mph, wind gust: out of the NNW to 10 mph, humidity 50%, dew point 38°, current snow level is near 6500' [yesterday, it was near 10,000'], observation time temperature was 42°, and the barometric pressure 30.06" and rising. |

Mid afternoon weather for 4/27-partly sunny (scattered Cirrus, Cirrostratus, and Cumulus), on a somewhat cooler spring afternoon. Temperatures are in the upper 60's to low 70's, BP 29.99"R along with nice air movement from the West and NW. Although at the present time, this area is enjoying partly cloudy skies and light winds, these conditions could be considered the lull before the storm as a strong storm-the second of two-will move through the area tonight through tomorrow afternoon generating sustained winds-from the "WSW-at 15-25 mph" with the "possibility of isolated gusts to 60 mph". At approximately "9AM Monday, the sustained winds will increase-now from the "West-to 30-40 mph" with "gusts up to 60 mph through Monday afternoon". These strong winds are a result of a "cold front crossing the region". Following the cool and windy weather-early this week-a ridge of high pressure is expected to build over WA {thereby heralding an end to the "conditions" just mentioned, and a return to dry conditions and warmer temperatures!} and remain through at least next weekend. Current conditions for 4/28-mostly sunny (scattered Cumulus, and widely scattered Cirrus and Cirrostratus), no precipitation in the last 24, the haze is light with light air movement. It is from the WNW at 5-6 mph, then the East at 3 mph, wind gust: out of the NW to 12 mph, humidity 62% {yesterday, the reading was 50%}, dew point 40°, current snow level is near 4500' [yesterday, it was near 6500'], observation time temperature was 39°, and the barometric pressure 30.07" and rising.

Mid afternoon weather for 4/28-mostly sunny (scattered Cirrus and Cumulus), temperatures are in the upper 60's to low 70's, BP 29.97"R along with nice air movement from the SW. Not much change from yesterday as this second system is packing quite a punch. Sustained winds today should increase from the West to 30-40 mph with gusts up to 50 mph. As was mentioned yesterday, these strong winds are a result of a "cold front crossing the region, which, when it passes, will usher in much colder air behind it. Although the "cooler" temperatures will be noticed in this area, the greatest impact will be at pass level where it is currently SNOWING on Snoqualmie pass with an additional 2-4" expected this morning. In addition, the minimum snow level is near 3500' and is expected to lower even further to near 2000' tonight through tomorrow. However, these cool and windy days are numbered as by tomorrow, a ridge of high pressure is expected to build over WA {thus heralding a return to dry conditions and warmer temperatures-"with the afternoon highs near ten degrees above average"} and remain through at least the weekend. Current conditions for 4/29-mostly clear (scattered Altocumulus, Cumulus and widely scattered Cirrus), windy-blowing dust is visible near Badger Mountain to the East-and cool. The wind is from the WNW at 9-14 mph, then the West at 6 mph, wind gust: out of the NW to 25 mph, humidity 62%, dew point 34°, current snow level is near 3000' [yesterday it was near 4500'], observation time temperature was 45°, and the barometric pressure 29.81" and falling. |

Mid afternoon weather for 4/29-partly cloudy (scattered Cumulus) and cool. Temperatures are in the mid to upper 50's-or about ten degrees below average-BP 29.96"F along with nice air movement from multiple directions including the East, SW, and West. Although high pressure is currently over the Pacific and West of SW OR, it is, however close enough to usher cool Canadian air over WA and keep high temperatures below average-which is 69°-for this last day of April. As a result, a freeze warning has been posted because an "unseasonably cool air mass coupled with calm winds and clear skies should set the stage for freezing temperatures" as the minimum temperatures are expected to reach "28-33 degrees between 1AM-8AM Wednesday". Then, at last, tomorrow through at least the weekend the high pressure, mentioned above, will not only be over WA but will have strengthened in the process resulting in dry conditions and warmer temperatures with the afternoon highs now reaching ten degrees above normal! Current conditions for 4/30-mostly cloudy (scattered Cumulus) and cool, no precipitation in the last 24, the haze is light with light air movement. It is from the West at 7-13 mph, then the North at 5 mph, wind gust: out of the WNW to 18 mph, humidity 45%, dew point 27° {yesterday, the readings were 62% and 34° respectively}, current snow level is near 2000', observation time temperature was 34°, and the barometric pressure 30.10" and rising. |

Mid afternoon weather for 5/01-mostly sunny (scattered high thin clouds-Cirrus) and pleasant. Temperatures are in the mid to upper 60's, BP 30.48"R along with nice air movement from multiple directions including the NE, East, SE, South, and SW as well as a splendid view of Glacier Peak to the NW! At last, the main weather event is a ridge of high pressure which is expected to remain over WA at least through the weekend into early next week. With the storm track north of the state as a result of this high pressure, the daytime highs by Monday should be in the mid to upper 70's and possibly nudging the low 80's! The only blemish to these pleasant conditions, is a very weak disturbance-no rain associated with it-that should move over WA sometime tomorrow; however, it is strong enough to generate some high level clouds over this area. Current conditions for 5/02-mostly clear (widely scattered Cirrus), no precipitation in the last 24, the haze is moderate with little or no air movement. It is from the North at 2-3 mph, then from the South at 5 mph, wind gust: out of the NNW to 12 mph, humidity 56%, dew point 33° {yesterday, the readings were 48% and 26° respectively}, current snow level is near 8500' [yesterday, it was near 5000'], observation time temperature was 38°, and the barometric pressure 30.53" and rising. |

Mid afternoon weather for 5/04-mostly clear (scattered Cumulus-dominant type-and widely scattered Cirrus) on a summer-like spring afternoon. Temperatures are in the upper 70's to low 80's-or about 10 degrees above normal-BP 30.01"F along with nice air movement mainly from the NE and East, but occasionally from the West plus another splendid view of Glacier Peak! It appears that high pressure-centered just West of the NW tip of Vancouver Island-will remain over WA for most of next week, and as a result, high temperatures should approach the mid to upper 80's with the possibility of nudging the low 90's by Tuesday! These warm temperatures are due, in part to the high pressure-mentioned above-as well as the NE "warm winds" flowing around it (or an offshore flow) which is quite an unusual pattern. Current conditions for 5/05-clear skies, no precipitation in the last 24, the haze is light with little or no air movement. It is from the West at 4-6 mph, then the East at 2 mph, wind gust: out of the WNW to 13 mph, humidity 46% {yesterday, the reading was 58%}, current freezing level is 11,000' observation time temperature was 46°, and the barometric pressure 30.04" and rising. |

Mid afternoon weather for 5/05-clear skies on a warm spring afternoon. Temperatures are in the low to mid 80's-which is about 14 degrees above average-BP 29.80"R along with nice air movement from the NE and East but to a lesser degree from the South. Strong high pressure will remain over WA through most of the week although a "cool onshore flow" returns tomorrow with cooler temperatures expected for SE Vancouver Island, Western WA (Seattle South and Westward) and OR {Portland South and Westward} while East of the Cascades very warm and dry conditions will prevail as high temperatures-which are well above normal-should reach the low to mid 80's today, the mid to upper 80's tomorrow and the likelihood of nudging the low 90's by midweek! Current conditions for 5/06-clear skies, no precipitation in the last 24, the haze is light to moderate with little or no air movement. It is from the West at 4-7 mph, then the SE at 3 mph, wind gust: out of the WNW to 15 mph, humidity 44%, dew point 38°, current freezing level is near 11,000', the observation time temperature was 46°, and the barometric pressure 29.90" and falling. |

Mid afternoon weather for 5/06-clear skies. Temperatures are in the mid to upper 80's, BP 29.69"F along with mostly calm winds. Little change since yesterday-except for the return of an onshore flow with cooler temperatures for much of Western WA-as high pressure over WA will keep high temperatures East of the Cascades unseasonably warm, and the NPJ well to the North over central BC. As a result, high temperatures should reach the mid to upper 80's today and tomorrow with the likelihood of nudging the low 90's both days! Unfortunately, all good things must come to an end and that includes this wonderful stretch of outstanding weather the past several days. There are indications of a cooling trend from the latter part of the weekend through early next week as the current high pressure will have moved East of WA by then, thereby opening the door for a trough to commence moving over WA in its place. As an indicator of this upcoming cooling trend, the freezing level is expected to drop from its maximum level of 12,000' on Friday, to a minimum level of 6500' by Monday. Current conditions for 5/07-clear skies, no precipitation in the last 24, the haze is light to moderate with little or no air movement. It is from the WNW at 3-4 mph, then the West at 2 mph, wind gust: out of the NW to 16 mph, humidity 42%, dew point 42°, current freezing level is near 10'500', observation time temperature was 51°, and the barometric pressure 29.78" and falling. |

Mid afternoon weather for 5/07-clear skies except for some widely scattered Cumulus. Temperatures are in the low to mid 90's (which is about 20 degrees above normal. The official high of 94° eclipsed the old record of 93° set on this day in 1984!), BP 29.74"F along with calm winds. High pressure-centered West of Vancouver Island-will remain over WA through the weekend at which time, it should strengthen somewhat before it moves east of the area early next week. As a result of this "movement", it was suggested yesterday that this would open the door for a trough to commence moving over WA in its-the high pressure-place. However, both the GFS and NAM models now show the trough moving NE over the Queen Charlottes into central BC therefore, it appears it will have little, if any influence to this area. In the meantime, the indications for a cooling trend are still in order as the freezing level is projected to drop from its maximum level of 12,000' on Friday, to a minimum level of 5000' by Monday. Last, by not least, the next three days are likely to by the warmest period of the week as high temperatures should reach the low to mid 90's all three days! Current conditions for 5/08-clear skies, no precipitation in the last 24, the haze is light to moderate with little or no air movement. It is from the North at 1-4 mph, then the South at 3 mph, wind gust: out of the NNW to 19 mph, humidity 53%, dew point 49° {yesterday, the readings were 42% and 42° respectively}, current freezing level is near 10,000', observation time temperature was 56°, and the barometric pressure 29.90" and rising. |

Mid afternoon weather for 5/08-clear skies except for scattered Cumulus toward the Northern, Eastern and Western to Southwestern horizons. Temperatures are in the low to mid 90's (which is well above normal-about 20-24 degrees-and close to another record high), BP 29.85"R along with light air movement from several directions including the NE, East, and South. Though high pressure is now centered over the SE tip of Vancouver Island and NW WA, it should remain over WA through much of the weekend and thus continue to bring very warm temperatures to Eastern WA for today and tomorrow with high temperatures likely to reach the low to mid 90's both days, the coastal area of WA and OR should be cooler compared to the past few days when the temperatures were well above normal. In the meantime, a cooling trend-mentioned yesterday-will subtly commence after tomorrow by dropping from a maximum level of 12,000' tomorrow, to a minimum level of 5000' early next week. This "lowering" of the freezing level is due, in part, to an area of rain that should affect Western WA sometime Saturday before moving "further inland Sunday and Monday". Current conditions for 5/09-clear skies, no precipitation in the last 24, the haze is light to moderate with little or no air movement. It is from the North at 3-5 mph, then from the SW at 2 mph, wind gust: out of the North to 14 mph, humidity 46%, dew point 47°, current freezing level is near 12,000' [yesterday, it was near 10,000'], observation time temperature was 53°, and the barometric pressure 30.03" and rising. |

Mid afternoon weather for 5/09-clear skies, temperatures are in the mid 90's (which is well above normal-once again, 20-24 degrees-and close to tying the record high of 98° on this day in 1948!), BP 29.91"R along with light air movement from the South. Although high pressure (now centered over the central Cascades of WA-and quite possibly near Mt. Rainier) will remain over WA today and tomorrow, it is in the process of breaking down. Otherwise, the weather should be a carbon copy of yesterday as this high pressure will continue to bring very warm temperatures to Eastern WA today and tomorrow. High temperatures are likely to reach the low to mid 90's both days and with the likelihood of threatening or tying the record high for this day. However, changes are in the offing in the form of a cooling trend which will subtly commence after tomorrow and should continue through mid week. A good indicator of this "trend" is the freezing level which will drop from a maximum level of 12,000' tomorrow, to a minimum level of 5500' by Wednesday. It is believed therefore, that the "lowering" of the freezing level is due, in part, to an area of rain that should affect Western WA sometime tomorrow before moving further inland Sunday and Monday. Current conditions for 5/10-clear skies, no precipitation in the last 24, the haze is moderate with very little air movement. It is from the WNW at 6-12 mph, then from the South at 3 mph, wind gust: out of the NW to 18 mph, humidity 44%, dew point 44°, current freezing level is near 12,000', observation time temperature was 52°, and the barometric pressure 30.10" and rising. |

Mid afternoon weather for 5/10-increasing cloudiness (scattered Cirrus, Cirrostratus and Cumulus) since earlier this morning when the skies were clear. Temperatures are in the low to mid 90's {or, about 18-23 degrees above normal and very close to tying the record high of 97° on this day back in 1949!}, BP 29.98"F along with light air movement from multiple directions including the NE, East,and South, but to a much lesser degree from the NW. Although it is mostly overcast in this area, high pressure over WA will continue to bring another day of dry conditions and very warm temperatures to Eastern WA but not quite as warm as yesterday. High temperatures for today should reach the upper 80's to low 90's. In addition, this high pressure-even though it is in the process of breaking down-is strong enough, for the time being, to keep a large area of rain just to the NW of WA. However, by sometime today or later tonight, the "large area of rain"-just mentioned-should begin to affect Western WA before moving inland Sunday and Monday [as the ridge of high pressure will have slid East over Eastern MT, ND, and WY with its apex over central Saskatchewan] thus heralding an end to the very warm temperatures of the past several days. These cooler conditions are expected to prevail through at least mid week with the high temperatures each day likely to be cooler than the previous day during this period. Using the freezing level, once again, as a case in point, it should drop from its maximum level of 12,500' today, to a minimum level of 5000' by early next week. Current conditions for 5/11-mostly cloudy (scattered Cirrus and Altocumulus), no precipitation in the last 24, the haze is moderate with little or no air movement. It is from the North at 3-6 mph, then the West at 2 mph, wind gust: out of the North to 16 mph, humidity 45%, dew point 46°, current freezing level is near 12,500', observation time temperature was 59°, and the barometric pressure 30.07" and falling. |

Mid afternoon weather for 5/11-mostly overcast (Cirrostratus, scattered Cirrus and Altocumulus), temperatures are in the upper 80's to low 90's, BP 29.93"F along with calm winds. Current conditions for 5/12-overcast {Altostratus and scattered Cumulus}, no precipitation in the past 24, the haze is light to moderate with some light air movement.

Mid afternoon weather for 5/12-mostly overcast (Cirrus, Cirrostratus and scattered Cumulus), temperatures are in the upper 70's to low 80's-or about 15-20 degrees cooler than 48 hours ago, and 10-15 degrees cooler than yesterday, BP 29.96"F along with light air movement first from the South then the NW. The very warm temperatures that were experienced in Eastern WA-near the end of the work week-are now a "distant" memory and not likely to return for awhile due, in part, to a cooling trend that commenced yesterday and is projected to prevail through much of the work week with high temperatures each day likely to be slightly cooler than the previous day. As a case in point, today's high temperatures should be in the mid to upper 70's compared to the upper 70's to low 80's of yesterday. Current conditions for 5/13-overcast (semi-transparent Altostratus and scattered Cumulus) and raining on or near the ridge South of of town-although it is not raining at this location-the haze is light to moderate with little or no air movement. It is from the North at 2-5 mph, then the South at 2 mph, wind gust: out of the NNW to 12 mph, humidity 67%, dew point 50°, current snow level is near 6500' [yesterday, it was near 9500'], observation time temperature was 54°, and the barometric pressure 29.95" and falling. |

Mid afternoon weather for 5/13-overcast and raining. Temperatures are in the upper 60's to low 70's, BP 29.83"F along with light air movement from the West and SW. The amount shown above was recorded yesterday, at the time given below. Even though it appears that weak high pressure is over WA, there is a slight SW air flow over the state. Meanwhile, high temperatures for today-and, for that matter-the remainder of the week, should reach the upper 60's to low 70's which is close to normal for this time in May. Current conditions for 5/14-mostly cloudy (scattered Cirrus, Cirrostratus and widely scattered Cumulus), no precipitation during the overnight, the haze is light to moderate with some air movement. It is first from the West at 6-8 mph, then the NW at 5 mph, wind gust: out of the WNW to 17 mph, humidity 45%, dew point 34° {yesterday, the readings were 67% and 50° respectively}, current snow level is near 4500' [yesterday, it was near 6500'], observation time temperature was 48°, and the barometric pressure 30.14" and rising. |

Mid afternoon weather for 5/14-clear skies, except for scattered Cirrus from the West to the North, temperatures are in the upper 60's to low 70's, BP 30.00"F along with nice air movement from the West. Today should feature showers for central and Southwestern BC, Vancouver Island, over and West of the Cascades of WA, and NW OR-although one model is showing a large band of moisture tracking East by NE that extends SE to NW over NW OR, the coastal areas and SW WA while at the same time approaching the Olympic Peninsula's West coast-as low pressure is off the NW coast of Vancouver Island-while Eastern WA should remain dry but "cool". Looking ahead to the weekend, it appears that the weather pattern should become more active as a trough moves inland over WA (with its southernmost boundary over Northern CA and NV) thereby allowing cooler air over WA and OR along with a chance for T-storms farther inland. Current conditions for 5/15-mostly cloudy (Cirrus, Cirrostratus, an immense halo! and widely scattered Altocumulus), no precipitation in the past 24, the haze is light to moderate with light air movement. It is first from the West at 3-7 mph, then the South at 3 mph, wind gust: out of the WNW to 12 mph, humidity 48%, dew point 37°, current snow level is near 6000' [yesterday, it was near 4500'], observation time temperature wa 45°, and the barometric pressure 30.05" and falling. |

Mid afternoon weather for 5/15-The clouds thickened from Cirrus and Cirrostratus earlier this morning to overcast (Altostratus and widely scattered Cumulus).
Temperatures are in the upper 60's to low 70's, BP 29.91"F along with light air movement from the South. From very warm and pleasant conditions last week to one of cool, "cloudy" and unsettled with showers in Western WA {Puget Sound westward} as well as Western OR and Northern CA due to a "depression"-shown by a Canadian model-off the coast of SE Vancouver Island. In the meantime, it appears that by the weekend, the weather pattern will become more active as a trough moves inland (with its Southern boundary now over Northern NV and UT} thus allowing for cooler air to move over WA. This cool and "wet weather" should persist through the weekend as "warmer and drier" conditions should return by early next week. Current conditions for 5/16-partly cloudy (scattered Cumulus though ominous toward the West, SW and East), no precipitation during the overnight, the haze is light to moderate with little air movement. It is first from the West at 0-5 mph, then from the East at 2 mph, wind gust: out of the WNW to 17 mph, humidity 67%, dew point 47° (yesterday, the readings were 48% and 37° respectively), current snow level is near 6000', observation time temperature was 53°, and the barometric pressure 29.91" and falling. |

Mid afternoon weather for 5/16-partly cloudy (scattered Cirrus, Altocumulus, Cumulus and Cumulus Congestus), temperatures are in the low to mid 70's, BP 29.81"F along with light air movement from the North. Although today should be somewhat of a carbon copy of yesterday with cool, "cloudy", and unsettled conditions, not to mention showers in WA {one model is showing several bands of light rain extending SE to NW and moving North over the central Cascades, Seattle to Everett and SE Vancouver Island} and OR, the bulk of a moist SW flow is taking aim at the central coast of BC and Vancouver Island while Western WA will be affected with the "left overs" for the time being. Behind this flow however, one model is showing a cold front tracking East by SE over the Alexander Archipelago, the Queen Charlottes but toward central BC, Vancouver Island, WA and OR. This becomes very interesting as much cooler air is likely to spread over WA by sometime early to mid week of next week. A good indicator of this "trend" is the freezing level will commence a gradual drop from a maximum level of near 6500' on Monday to a minimum level of just 3000-3500' by mid week. WOW! Current conditions for 5/17-mostly cloudy (scattered Cirrus, Cirrostratus, Altostratus, Cumulus, Cumulus Congestus-and looking very ominous to the SW and South), the haze is light to moderate with some light air movement. It is first from the West at 2-5 mph, then the SW at 2 mph, wind gust: out of the WNW to 14 mph, humidity 67%, dew point 47°, current snow level is near 6000' , observation time temperature was 51°. and the barometric pressure 29.88" and falling.

The amount recorded yesterday, is shown at the times given below. Mid afternoon weather for 5/17-mostly overcast (scattered Cirrus, Cirrostratus, Altocumulus and Cumulus), temperatures are in the upper 60's to low 70's, BP 29.85"F along with some nice air movement first from the West, then the NE. The moist SW flow that yesterday had taken aim at the central coast of BC and Vancouver Island, has since switched to a cool and moist westerly flow across the PNW. As a result, the coastal areas-of WA- and the I-5 corridor from Seattle to Portland will likely see showers "as the day progresses" as the cool, cloudy, and unsettled conditions continue. Early next week should begin somewhat "warmer and drier; however, these pleasant conditions will abruptly change toward mid week and beyond as much cooler air will move over WA due to a "cold system diving in from the North". In response to this cooler air, the minimum freezing level will be near 3000' Tuesday night and Wednesday, then moderate slightly and stay between 4000'-4500' through the end of the work week. High temperatures during the period should only reach the upper 50's to low 60's before rebounding somewhat by the end of the work week. Current conditions for 5/18-mostly cloudy {scattered Cirrus, Cirrostratus, Altocumulus, and Cumulus}, no precipitation during the overnight, the haze is light to moderate with some nice air movement. It is first from the WNW at 9-11 mph, then the NW at 7 mph, wind gust: out of the NW to 14 mph, humidity 45%, dew point 38° (yesterday, the readings were 67% and 47° respectively), current snow level is near 5000' [yesterday, it was near 6000'], observation time temperature was 56°, and the barometric pressure 29.97" and falling. |

Mid afternoon weather for 5/19-mostly clear (scattered Cumulus) on a very pleasant spring afternoon. Temperatures are in the low to mid 70's, BP 30.17"R along with nice air movement from the West. Another beautiful, benign day is in the offing with continued dry conditions and warmer temperatures than yesterday as high temperatures should reach the low to mid 70's. However, these conditions are deceptive as they will drastically change toward mid week and beyond due to a potent upper level low-along with a strong cold front-that is forecast to "drop over NW WA-from the North-by Tuesday and "remain nearly stationary through the weekend". In addition, there is the "potential for gusty winds and thunderstorms". In response to this cooler air, the freezing level will "drop" from a maximum level of 10,000' today, to a minimum level of 3500' by tomorrow night into Wednesday then moderate somewhat and stay between 4000'-5500' through the end of the work week. High temperatures during this period should reach the low mid 50's before rebounding to some degree by Friday. Current conditions for 5/20-increasing cloudiness since earlier this morning (scattered Cirrus, Cirrostratus, an immense halo! and widely scattered Cumulus), no precipitation in the last 24, and light to moderate haze with little or no air movement. It is first from the North at 2-5 mph, then the SE at 3 mph, wind gust: out of the North to 16 mph, humidity 54% {yesterday, the reading was 41%}, dew point 42°, current freezing level is near 10,000' [yesterday, it was near 5500'], observation time temperature was 47°, and the barometric pressure 30.25" and rising. |

Since earlier this morning when a trace was recorded, an additional 0.43" fell for a grand total of 0.43". Mid afternoon weather for 5/20-partly cloudy (scattered Cirrus and Cumulus), temperatures are in the upper 70's to low 80's, BP 29.97"F along with nice air movement from the South. Although it was relatively mild, overcast, and raining-all morning-in this area, even these rather benign conditions are deceiving as a drastic change is in the offing for later today, tomorrow and beyond due to a potent upper level low and a strong cold front {which is expected to move across the Cascades around midday then continue to track NE through late afternoon} associated with it that should drop over NW WA later today, then "remain nearly stationary through the weekend". In response to the passage of the cold front, cool air behind it will bring the snow level down from a maximum level of 6500' today, to a minimum level of just 3500' tomorrow. As if that wasn't enough, a total of 2-7" of SNOW is expected in the passes! WOW! As a result, high temperatures during this period should reach the low to mid 50's. There is some light at the end of the tunnel however, as the snow level should moderate somewhat and stay between 5000'-6000' near the end of the workweek through Saturday. Current conditions for 5/21-overcast and low clouds but not raining. The haze is light with little or no air movement at the present time. It was first from the WNW at 3 mph, then the North at 4 mph, and finally the West at 3 mph, wind gust: out of the WNW to 15 mph, humidity 84%, dew point 50° {yesterday, the readings were 54% and 42° respectively}, current snow level is 6500' lowering to 4500' later this afternoon, observation time temperature was 53°, and the barometric pressure 29.68" and falling. |

Mid afternoon weather for 5/21-from overcast and rainy skies earlier this morning to partly cloudy this afternoon (Cirrus, Altocumulus and Cumulus). Temperatures are in the upper 50's to low 60's, BP 29.67"F along with light air movement from the South. The "main story" for the past several days has been the potent upper level low which is now centered off the coast of NW OR-according to a Canadian model-that should remain nearly stationary through the weekend, even though it is moving slowly NE. The air circulating around this upper level low from the SE should "maintain an overall unstable atmosphere". Meanwhile, because the snow level is near 3500', 1-6" are expected on both Snoqualmie and Stevens passes; however, a "winter advisory has been posted for heavier amounts (4-9") above 5000' through tonight". Current conditions for 5/22-in addition to some air movement, it is overcast and raining on the East side as well as on or near Badger Mountain to the East. It is first from the WNW at 2 mph, then the North at 2 mph, and finally the East at 2 mph, wind puff: out of the North to 7 mph, humidity 94%, dew point 43° {yesterday, the readings were 84% and 50° respectively}, current snow level is near 3500' [yesterday, it was near 4500'], and the barometric pressure 29.78" and rising. |

Since the time that 0.40" was recorded by mid morning yesterday, off and on showers during the course of the day resulted in an additional 0.32" for a grand total of 0.72". Mid afternoon weather for 5/22-overcast with off and on showers. Temperatures are in the low to mid 50's-which is now about 20-25 degrees BELOW normal for this day in May-BP 29.88"R along with slight air movement from the West. It appears that this upper level low (that brought much cooler air to the region-which resulted in below normal high temperatures for the past few days-rain, and even snow to the passes) is in its latter stages as by sometime tomorrow, there are indications of it commencing to "weaken and depart" the area which would then allow for more "stable conditions" and "warmer high temperatures" {as a case in point, the high temperatures by Memorial day should be in the mid to upper 60's with the possibility of nudging the low 70's}. In the meantime, the upper level low has "stalled" near the Seattle area, but continues to produce showers over most of Southern Alberta and BC (in an attempt at conforming to the counterclockwise rotation) as well as Western WA-where precipitation is in the form of rain/showers in the lowlands and snow at pass level as the snow level is currently between 3500-4000'-OR and NW CA. Current conditions for 5/23-overcast with light rain falling on or near Badger Mountain to the East, and light to moderate haze with light air movement. It is first from the ESE at 4 mph, then the SE at 4 mph, wind puff: out of the SE to 9 mph, humidity 78% (yesterday, the reading was 94%), dew point 43°, current snow level is near 4000', observation time temperature was 49°, and the barometric pressure 29.98" and rising.

Mid afternoon weather for 5/23-mostly cloudy (Cirrus, Cirrostratus, Cumulus-dominant cloud type-and a moderate area of Cumulus Congestus from the NW to the NE), temperatures are in the upper 50's to low 60's, BP 29.96"R along with light air movement from the NE. The cold upper level low-now centered over SW WA-should keep WA on the cool side today with showers in Western WA (including the coastal areas) and the likelihood of snow down to pass level. However, as was indicated yesterday, this cold upper level low should begin to weaken today and depart the area {as it is projected to track NE over SE BC and the coldest air associated with it over NE WA} which would allow for more stable conditions and somewhat warmer temperatures by early next week. High temperatures-especially on Memorial day-should reach the mid to upper 60's with a possibility of nudging the low 70's. Current conditions for 5/24-overcast, no precipitation during the overnight, the haze is light to moderate with little or no air movement. It is first from the WNW at 3-7 mph, then the NW at 3 mph, wind gust: out of the NW to 12 mph, humidity 75%, dew point 43°, current snow level is near 4000', observation time temperature was 46°, and the barometric pressure 29.94" and rising.

Mid afternoon weather for 5/24-mostly cloudy (Cumulus-dominant cloud type) and very ominous from the West to the SW. Temperatures are in the low to mid 60's, BP 29.94"R along with nice air movement from multiple directions including the West, NW, NE and SE. Although the cold upper level low of the past several days (that brought a variety of weather to WA including very cool air-resulting in below normal high temperatures during this period in May-rain, and even SNOW down to pass level) has indeed moved NE over southern Alberta, though the coldest air associated with it should keep NE WA rather cool for the time being. The passage of this cold upper level low should allow for more stable conditions and somewhat warmer temperatures by early next week. High temperatures-especially on Memorial day-are likely to reach the mid to upper 60's with a possibility of nudging the low 70's. In the meantime, spotty showers are likely for WA {though one model is showing one large band tracking East by NE over the coastal areas of WA-including the Olympic Peninsula-while a second band is approaching the NW coast of OR} and OR due to yet another-but "much weaker" low pressure than the previous one-just off the NW coast of WA. Current conditions for 5/25-mostly cloudy (scattered Cumulus and Cumulus Congestus), no precipitation in the last 24, the haze is light to moderate with light air movement. It is first from the WNW at 4-7 mph, then the South at 2 mph, wind gust: out of the NW to 11 mph, humidity 66%, dew point 42°, current snow level is near 4500', observation time temperature was 43°, and the barometric pressure 29.98" and rising.

Mid afternoon weather for 5/25-mostly cloudy (scattered Altocumulus and Cumulus), temperatures are in the mid to upper 60's, BP 29.92"R along with light air movement first from the East, then the South. The cold upper level low of the past several days that brought a variety of weather to WA, has indeed moved NE over Southern Alberta near the northern Canadian Rockies. In the meantime, it was thought with the passage of the cold upper level low that the "atmosphere" would become more stable; however, this does not seem to be the case as wide spread spotty showers are in store for much of WA, OR, Southern BC and Alberta due in part to the cold upper level low-mentioned above-and another low pressure over SE Vancouver Island/NW WA. Even the high temperatures for the next few days-and especially Memorial day-will be affected to some extent with the highs struggling to reach the mid to upper 60's as the "weather" continues to remain on the cool side due to a trough that has "slid" over WA-with its southern boundary over Southern CA-which should result in showers and continued cool conditions. Current conditions for 5/26-overcast, no precipitation in the last 24, the haze is light to moderate with little or no air movement. It is first from the North at 2-4 mph, then the South at 3 mph, wind gust: out of the NNW to 12 mph, humidity 75%, dew point 45°, current snow level is near 6500' [yesterday, it was near 4500'], observation time temperature was 49°, and the barometric pressure 29.95" and rising. |

The amount shown was recorded yesterday at the times indicated below. Mid afternoon weather for 5/27-from a high thin overcast and widely scattered Cumulus earlier in the day to overcast and rain. Temperatures are in the upper 50's to low 60's-which is about 17-19 degrees below normal for this day in May-BP 29.78"F along with calm winds. Although drier air has moved over most of Western OR while simultaneously nearing the coasts of Vancouver Island and WA, it seems as though the persistent showers, below normal high temperatures, and somewhat unsettled conditions will be the norm for the next few days (though Eastern WA should remain dry) with light off and on rain showers likely in SW BC, Vancouver Island, WA {where one model is showing scattered showers in NW OR, SW and Western WA. In addition, a narrow band of precipitation is moving NE over the West side of the Olympic Peninsula while a second and larger band is slowly moving NE over SE Vancouver Island and Vancouver, BC} and OR due in part to low pressure off the central coast of Vancouver Island, and a "cool and moist" onshore flow over both WA and OR. Looking ahead to the end of the work week and the first part of the weekend, it appears that the PNW-and "coastal areas"-should commence to "dry out" somewhat before the next system "comes through" late in the weekend. Current conditions for 5/29-mostly cloudy (Cumulus) and very ominous to the SW, no precipitation during the overnight, and light air movement. It is first from the WNW at 2 mph, then the South at 5 mph, wind puff: out of the NW to 8 mph, humidity 74%, dew point 50°, current snow level is near 6000', observation time temperature was 52°. and the barometric pressure 29.79" and falling. |

After 0.10" was recorded by mid morning yesterday, intermittent showers resulted in an additional 0.03" for a grand total of 0.13". Mid afternoon weather for 5/29-mostly overcast (Cumulus) with intermittent light showers. Temperatures are in the upper 50's to low 60's, BP 29.72"F along with light air movement from the North. The NPJ is in a NW flow over NE CA thereby allowing cool air over much of WA and OR along with widely scattered spotty showers. Although the "forecast" called for improving conditions tomorrow through the weekend before "more wet weather returns by the end of the weekend to early next week", it is believed that the cool, wet, and unsettled conditions of the past week will finally come to an end and that the improvement should indeed transpire tomorrow as high pressure-off the SW coast of WA-begins to "push the storm track further North". However, the weekend looks to be on the "cool" side as, once again, using the freezing level as an indicator, the snow level will drop from a maximum level of 8500' on Saturday to a minimum level of 6500' by Sunday due to low pressure "sliding" SE from near the Queen Charlottes to Southern BC. It is further believed that instead of "wet weather returning by the end of the weekend to early next week", summer like weather-with very warm temperatures-should make another appearance as the freezing level will abruptly rise to 9000' by Sunday evening and reach a maximum level of 13,500' by mid week. Current conditions for 5/30-mostly clear (scattered Cumulus), no precipitation during the overnight, the haze is light with some nice air movement. It is first from the West at 5-15 mph, then the NW to 5 mph, wind gust: first out of the NW to 19 mph, then the West to 20 mph, humidity 47%, dew point 41° {yesterday, the readings were 91% and 49° respectively}, current snow level is near 5000', observation time temperature was 49°, and the barometric pressure 29.94" and rising. |

Mid afternoon weather for 5/30-mostly clear (widely scattered Cumulus) on a very pleasant spring afternoon. Temperatures are in the upper 60', BP 29.99"R along with nice air movement first from the West, then the NE. The cool, wet, and unsettled weather of the past week, appears to have ended as high pressure off the coast of OR has begun to push the storm track further north, thereby insuring improving weather for today that should last through mid week of next week. Progressing toward mid week, summer like weather-and very warm temperatures-should make another debut as the freezing level will abruptly rise to 9000' sometime tonight and reach a maximum level of 14,000' by mid week. The only blemish to these warm and dry conditions should occur by sometime Sunday, as low pressure will slide SE over WA from Vancouver Island. Current conditions for 5/31-partly cloudy (scattered Cumulus), no precipitation during the overnight, the haze is light with little or no air movement. It is first from the West at 5 mph, then the NW to 5 mph, wind gust: out of the WNW to 14 mph, humidity 41%, dew point 38°, current snow level is near 5500', observation time temperature was 49°, and the barometric pressure 30.20" and rising. |

Mid afternoon weather for 5/31-partly cloudy (scattered Cirrus, and Cumulus) on a very pleasant spring afternoon. Temperatures are in the mid 70's, BP 30.15"R along with light air movement from the South. Current conditions for 6/01-mostly cloudy (scattered Cirrus, Altocumulus, and Cumulus), no precipitation in the last 24, the haze is light to moderate with little or no air movement. It is first from the North at 0 mph, then the SE at 2 mph, wind gust: out of the NNW to 14 mph, humidity 57%, dew point 45° { yesterday, the readings were 41% and 38° respectively}, current snow level is near 7500' [yesterday, it was near 5500'], observation time temperature was 53°, and the barometric pressure 30.16" and rising. Here are some interesting stats for MAY- 1) total rain: 1.49" or 532% of average. It also helped reduce the rain deficit from 2.10" in April, to 0.89" for May. 2) number of days with no precipitation: 23, 3) high BP: 30.53" on 5/02, 4) low BP: 29.66" on 5/29, 5) date with low BP and no precipitation: 29.78" on 5/07, 6) date with high BP and precipitation: 29.88" on 5/17 (0.04"), 7) average BP: 30.01", 8) average morning temperature-a) official minimum: 49.1°, b) normal low: 46.6°, c) digital: 50.9°, 9) low morning temperature- a) official minimum: 30° on 5/01, b) digital: 32.7° on 5/01, 10) high morning temperature-a) official maximum: 61°, b) digital: 63.5°, 11) average afternoon temperature-a) official maximum: 77.5°, b) normal high: 73.8°, c) digital: 75.3°, 12) low afternoon temperature-a) official minimum: 61° on 5/27, digital: 58.5° on 5/27, and 13) high afternoon temperature-a) official maximum: 96° on 5/09, b) digital: 95.9° on 5/09. |

Mid afternoon weather for 6/01-partly to mostly cloudy (scattered Cirrus, Cirrostratus, Altocumulus and Cumulus), on a pleasant spring afternoon. Temperatures are in the upper 70's to low 80's, BP 29.95"F along with light air movement first from the West, then the South, and finally the North. The day before yesterday, it was mentioned that high pressure off the coast of OR had begun to push the storm track further North, thereby insuring improving weather then that should last at least through mid week. High temperatures during this period should reach the mid to upper 70's tomorrow, and the low to mid 80's by Tuesday. The only blemish to these warm and dry conditions should occur by sometime today (which already took place earlier this morning in the form of a brief shower) as low pressure slid SE over Southern BC from near the Queen Charlottes. However with low pressure over Southern BC, Southern BC and Alberta should receive the bulk of the "showers', while the "North Cascades" and northern boundary counties of WA get scattered showers although there is a chance for "thunderstorms early this morning and into the afternoon" from the Spokane area to Pullman". Current conditions for 6/02-partly cloudy {scattered Cumulus}, the haze is light to moderate with some nice air movement. It is first from the WNW at 6 mph, then the NW at 6 mph, wind gust: also out of the NW to 15 mph, humidity 43% ( yesterday, the reading was 57%), dew point 44°, current snow level is near 6500' [yesterday, it was near 7500'], observation time temperature was 54°, and the barometric pressure 29.95" and falling. |

Mid afternoon weather for 6/02-partly cloudy (scattered Cumulus), on a pleasant spring afternoon. Temperatures are in the mid to upper 70's, BP 29.87"F along with nice air movement first from the South, then the NW. With the passage of yesterday's "system"-the results of which was a brief shower in this area-high pressure has established itself off the WA/OR coast for the next several days that should bring warm, dry, and generally pleasant conditions to WA for at least the remainder of the week if not longer. High temperatures for today should reach the mid to upper 70's, low to mid 80's by tomorrow and the mid to upper 80's with a possibility of nudging the low 90's Wednesday. However, the only "blemish" to this week's very pleasant conditions appears to be a slight cooling trend from mid week through the end of the work week though it probably will go unnoticed in Eastern WA anyway, as the freezing level during this period will still be quite high. Current conditions for 6/03-partly cloudy (scattered Cumulus), no precipitation in the last 24, the haze is light to moderate with light air movement. It is first from the West at 5-6 mph, then the East at 4 mph, humidity 46%, dew point 45°, current freezing level is near 10,000' (yesterday, it was near 6500'), observation time temperature was 52°, and the barometric pressure 29.99" and falling. |

Mid afternoon weather for 6/03-partly cloudy (scattered Cumulus), temperatures are in the upper 70's to low 80's, BP 29.89" along with nice air movement first from the SW then the West. Very little change since yesterday as high pressure has established itself off the Southern coast of OR-which should strengthen tomorrow thereby keeping the storm track north of WA over Southern BC-and persist through at least the end of the work week of not longer. As a result of this high pressure, today should be similar to yesterday with generally pleasant conditions as well as being warm and dry. High temperatures will be "above normal"-especially for the days mentioned below-as they should reach the low to mid 80's today, the mid to upper 80's along with a chance of nudging the low 90's are likely tomorrow. However, the warmest period is projected for the end of the work week and again on Sunday as high temperatures are likely to reach the low to mid 90's. Current conditions for 6/04-mostly clear (widely scattered Cirrus and Cumulus), no precipitation in the last 24, the haze is light to moderate with little or no air movement. It is first from the West at 2-4 mph, then the SE at 2 mph, wind gust: out of the WNW to 13 mph, humidity 56% {yesterday, the reading was 46%}, dew point 47°, current freezing level is near 12,500' [yesterday, it was near 10,000'], observation time temperature was 52°, and the barometric pressure 30.10" and rising. |

Mid afternoon weather for 6/04-mostly clear (scattered Cirrus and Cumulus), temperatures are in the mid 80's, BP 29.96"R along with light air movement from the SE. Some subtle changes have occurred to yesterday's ridge of high pressure. Although it was stated yesterday that high pressure had established itself off the Southern coast of OR, and that it should strengthen today thereby keeping the storm track North of WA over Southern BC has, in fact, flattened somewhat and slid South over Northern CA. However, both the GFS and NAM models show it rebuilding quite nicely by sometime tomorrow and persisting at least through the end of the work week. High temperatures for today should reach the mid to upper 80's with the possibility of nudging the low 90's. Whether or not these maximum temperatures are reached depends on two conditions: 1) if the "cloudiness" over this area dissipates, and 2) if windy conditions develop as one model is showing a low pressure over SW BC along with a cold front tracking East by SE across central WA and NW OR. Current conditions for 6/05-partly to mostly cloudy (scattered Cirrus, Cirrostratus, and Altocumulus), no precipitation in the last 24, the haze is moderate with little or no air movement. It is first from the North at 1-5 mph, then the SE at 2 mph, wind gust: out of the NNW to 14 mph, humidity 54%, dew point 51°, current freezing level is near 12,500', observation time temperature was 55°, and the barometric pressure 29.99" and rising. |

Mid afternoon weather for 6/06-a mostly high thin overcast (Cirrus, Cirrostratus and a very large halo!), temperatures are in the upper 80's to low 90's, BP 29.87"F along with light air movement first from the West, then the NW. Since yesterday, the ridge of high pressure did indeed rebuild quite nicely and should remain over WA through most of tomorrow. High temperatures for today should, once again, reach the mid to upper 80's with yet another possibility of nudging the low 90's. However, some changes are forthcoming later tomorrow as the current high pressure will flatten to a near zonal flow over WA before weakly rebuilding the following day (Saturday)In addition, the "second of two cold fronts" should move through the area sometime tomorrow and will likely generate windy conditions and noticeably cooler high temperatures-compared to the last few days-with its passage. As a further indicator of these "cooler temperatures", the freezing level will drop from its maximum level of 13,500' today, to a minimum level of 12,000' tomorrow. Current conditions for 6/06-mostly clear (widely scattered Cirrus and Cirrostratus), no precipitation in the last 24, the haze is light to moderate with little or no air movement. It is first from the West at 1-4 mph, then the South at 3 mph, wind gust: out of the WNW to 16 mph, humidity 46%, dew point 50°, current freezing level is near 13,500' [yesterday, it was near 12,500'], observation time temperature was 66°, and the barometric pressure 29.97" and rising.

Mid afternoon weather for 6/07-mostly clear (widely scattered Cumulus), temperatures were noticeably cooler-low to mid 80's-than yesterday's high temperatures (upper 80's to low 90's), BP 29.88"F along with gusty winds {mainly from the NW or North while on the "summit" of Saddlerock to the SW} and wind-though much less intense-from first the East then the South. Although today will be warm and dry in Eastern WA-with high pressure off the coast of Northern CA-high temperatures will be cooler (though pleasant with highs in the upper 70's to low 80's) than what was experienced earlier this week (upper 80's to low 90's) because of yesterday's cold front that moved across WA and as a result, the "heat" moved south over "Southern OR and Northern CA" where high temperatures are "expected to be in the triple digits across the region just mentioned. Meanwhile, there are indications of another cooling trend commencing tomorrow and lasting through mid week during which time the maximum freezing level will decline from a maximum level of 12,500' tomorrow to a minimum level of 5500' by Wednesday morning before rising to 7000' later in the afternoon of the same day. This "cooling is due in large part to an upper level low that will be approaching the state "early in the week, cross the state by "mid week", and finally exiting the state near the end of he work week according to both the GFS and NAM models. Current conditions for 6/08-clear skies, no precipitation in the last 24, the haze is light to moderate with sustained light air movement. It is first from the West at 6-8 mph, then the NW at 5 mph, wind gust: out of the West to 17 mph, humidity 38%, dew point 41°, current freezing level is near 13,500', observation time temperature was 61°, and the barometric pressure 30.01" and falling. |

Mid afternoon weather for 6/08-except for a few widely scattered Cumulus, the skies are clear. Temperatures are in the mid 80's, BP 29.88"F along with nice air movement first from the North, then the West, and finally the South. Although high temperatures today will be pleasant though cooler (upper 70's to low 80's) than yesterday (low to mid 80's), it appears that these "cool" but pleasant conditions should persist through tomorrow as sharp changes are on the way after tomorrow through mid week. For starters, the freezing level will "CRASH" from a maximum level of 11,000' on Monday evening to a minimum level of just 5500' on Thursday. High temperatures during this period will struggle to reach the mid to upper 60's. This lowering of the freezing level is due, in large part, to a cold front tracking East by SE across WA, Northern ID, NE to SW OR and should usher in much cooler air behind it over WA along with the possibility of windy conditions. Another factor is the upper level low that will be approaching the state "early in the week", cross the state by "mid week" and finally exit the state near the end of the work week even though both the GFS and NAM models suggest that some kind of "trough" will persist through most of next week. Current conditions for 6/09- clear skies (except for a few scattered Cumulus to the South),no precipitation in the last 24, the haze is light to moderate with some nice air movement first from the West at 4-10 mph, then the NW at 5 mph, wind gust: out of the WNW to 17 mph, humidity 36%, dew point 39°, current freezing level is near 11,500' [yesterday, it was near 13,500'], observation time temperature was 61°, and the barometric pressure 29.95" and falling. |

Mid afternoon weather for 6/09-clear skies, temperatures are a few degrees cooler than yesterday with highs reaching the upper 70's to low 80's along with light air movement first from the West, then the South, and finally the NW. A trend has developed the past few days where each successive day has been a few degrees cooler than the previous one and today is no exception as high temperatures should reach the mid to upper 70's. However, some noticeable changes are on the way after today as one model is showing low pressure over the central Alberta/Saskatchewan border along with a cold front tracking East by SE
over most of MT, the panhandle of ID, OR, and Northern CA (near the OR border). With the passage of this cold front sometime later today, much cooler air is likely to be ushered in over WA {which should remain through the second half of the work week} along with the probability of windy conditions. In response to the much cooler air, the freezing level will crash from a maximum level of 11,500' today, to a minimum level of just 5000' by Thursday, and high temperatures will struggle to reach the mid to upper 60's during this period. Another factor is an upper level low that continues to approach the state, and should cross the state by the end of the work week then finally exit the state by the following day according to both the GFS and NAM models. Current conditions for 6/10-clear skies (except for some widely scattered Cumulus to the North and South), no precipitation in the last 24, the haze is light to moderate in quality along with light air movement. It is first from the West at 8 mph, then the NW to 6 mph, wind gust: out of the West to 18 mph, humidity 37%, dew point 37°, current freezing level is near 11,000', observation time temperature was 54°, and the barometric pressure 29.89" and falling. |

Mid afternoon weather for 6/10-clear skies except for a few scattered Cumulus to the West and North. Temperatures are in the upper 70's to low 80's. BP 29.68"F along with calm winds. Yesterday, a few miscalculations were made by this observer one of which included the high temperature range for the day (mid to upper 70's instead of the upper 70's to low 80's) while the other was much cooler air would be ushered in over WA with the passage of a cold front which, obviously did not happen. However, the statement that 'noticeable changes are on the way' needs to be reiterated as one model shows a cold front tracking East by SE over Eastern WA, NE to SW OR, and extreme NW CA along with low pressure over Southern BC. With the passage of this cold front, much cooler air will be ushered in over WA along with the likelihood of generating very windy conditions including gusts of 25-35 mph by this afternoon. In addition, tomorrow and Thursday appear to be the coldest period of the week as high temperatures will struggle to reach the mid to upper 60's in Eastern WA. Current conditions for 6/11-partly cloudy (scattered Cumulus), no precipitation in the last 24, the haze is light to moderate even with breezy conditions. It is first from the West at 7-14 mph, then the NW at 7 mph, wind gust: out of the WNW to 23 mph, humidity 46%, dew point 43°, current snow level is 6500' lowering to 5000' later on this afternoon, observation time temperature was 59°, and the barometric pressure 29.79" and falling. |

Mid afternoon weather for 6/13-partly cloudy (scattered Cumulus and Cumulus Congestus) on a very nice late spring afternoon. Temperatures are in the upper 60's to low 70's, BP 29.94"R along with light air movement first from the NE, then the East, and finally the SE. Today should be the last of the "cool" period as one model shows a "pesky" low pressure over North central Alberta, and another over NW OR along with a deep trough (with its southern boundary over Northern CA-near Lake Tahoe) over WA that will assist in maintaining cool and unsettled conditions and "showers" in SW WA and NW OR as well as a "chance for showers or thunderstorms" in Eastern WA. However, there are indications that a slow warming trend appears to be on the way which will commence tomorrow and culminate by sometime Sunday. The weekend looks to be sunny and warm with high temperatures likely to be in the mid to upper 80's and a possibility of nudging the low 90's! Current conditions for 6/13-partly cloudy (scattered Altocumulus, Cumulus, Cumulus Congestus while looking very ominous from the SW to the South), no precipitation in the last 24-although yesterday, there was a brief shower-,the haze is light to moderate with light air movement. It is first from the West at 4-7 mph, then the South at 6 mph, wind gust: out of the West to 14 mph, humidity 49%, dew point 41° {yesterday, the readings were 30% and 35° respectively}, current snow level is near 5500', observation time temperature was 52°, and the barometric pressure 30.05" and rising. |

Mid afternoon weather for 6/16-mostly cloudy (Cirrus, Cirrostratus, Altostratus, and widely scattered Cumulus), temperatures are in the upper 80's to low 90's, BP 29.86"F along with very light air movement from the NW. It appears that the warm and generally pleasant conditions of the past few days will come to a temporary end as low pressure off the Northern WA coast will finally move inland and bring cooler air, unsettled conditions and showers to Western WA. However, there are indications that the low pressure-mentioned above-will shift SE near the Portland area, and as a result, the air flow over central WA will be from the SE-according to both the GFS and NAM models-thereby increasing the chances of rain in Eastern WA. Current conditions for 6/17-partly cloudy (scattered Cirrus, Cirrostratus, Altocumulus and Cumulus), no precipitation in the last 24, the haze is moderate with light air movement. It is first from the North at 5-10 mph, then the NW at 5 mph, wind gust: out of the NNW to 22 mph, humidity 43%, dew point 50°, current snow level is near 8000', observation time temperature was 65°, and the barometric pressure 29.95" and falling. |

Mid afternoon weather for 6/18-overcast with intermittent light sprinkles. Temperatures are in the upper 60's to low 70's-which is about 12 degrees below normal for this day in June-BP 29.86"F along with light air movement from the South. Current conditions for 6/19-mostly overcast {except for some partial clearing in the West}. Although it stopped raining a little bit ago, we have light haze even though there is nice air movement. It is first from the West at 5-7 mph, then the NW at 5 mph, wind gust: out of the WNW to 15 mph, humidity 76% (yesterday, the reading was 55%), dew point 49°, current snow level is near 6500', observation time temperature was 58°, and the barometric pressure 29.78" and falling. |

Mid afternoon weather for 6/21-mostly overcast (Altocumulus and Cumulus), temperatures are in the low to mid 70's-which is still 8-10 degrees below normal for this day in June-BP 30.04"R along with light air movement first from the East, then the SE and finally the South. The low pressure that brought cool and showery conditions to the area for the past few days has moved SE over Southern ID, and in its place, it appears that a break from the conditions just mentioned are in order for today and tomorrow as weak high pressure (off the Vancouver Island coast) will bring "generally dry conditions"-except for North eastern WA where light scattered showers are likely-and "comfortable" temperatures as highs both days should reach the mid to upper 70's. Unfortunately, however, by the beginning of the week, there are indications of a return to cool and showery conditions. Current conditions for 6/22-partly cloudy (scattered Cirrus, Altocumulus and Cumulus), no precipitation in the last 24, the haze is light with little or no air movement. It is first from the West at 2-4 mph, then the NE at 3 mph, wind gust: out of the WNW to 12 mph, humidity 60%, dew point 50°, current freezing level is near 10,000', observation time temperature was 52°, and the barometric pressure 30.04" and rising. |

Although a trace was recorded at observation time, an additional 0.04" was received for a total of 0.04"-so far! Mid afternoon weather for 6/23-from high thin clouds earlier this morning, to overcast (Altostratus and Cumulus) and light rain. Temperatures are in the upper 70's, BP 29.68"F along with light air movement from the South. Low pressure off the WA/OR coast should bring showers to Western WA (where one model shows a large band of precipitation tracking North and extends SW to NE from the SE corner of WA to Wenatchee along with light scattered showers over Western, South western and Southern WA) with the heaviest rain likely to occur sometime tomorrow. In the meantime, this cool air and wet weather should persist through mid week before turning dry and much warmer by the end of the work week through at least the weekend as strong high pressure {both at the surface and aloft} moves over the area according to both the GFS and NAM models. Current conditions for 6/24-overcast with intermittent light showers. Prior to these showers, the haze was moderate with little or no air movement. It was first from the NW at 5-6 mph, then the East at 2 mph, wind puff: out of the East to 7 mph, humidity 77%, dew point 57° {yesterday, the readings were 53% and 51° respectively}, current snow level is near 7500' [yesterday, it was near 10,000'], observation time temperature was 60°, and the barometric pressure 29.58" and falling. |

It was stated on 6/24 that after a trace was received at observation time, an additional 0.04" was recorded for a total of 0.04" for the time being. During the course of the day, an additional 0.22" was recorded for a grand total of 0.26". Although low pressure SW of the Queen Charlottes should bring showers to Vancouver Island, the coastal areas of WA and NW OR, the cool and showery weather of the past few days are numbered as big changes are on the way-HEAT! Strong high pressure both at the surface {according to the GFS and NAM models, this high pressure will migrate North over WA, OR, ID, and bring heat from the SW along with it} and aloft will bring dry conditions and much warmer temperatures by the end of the work week through the weekend and into early next week. As a case in point, these temperatures will be "well above normal" during this period-mentioned above-with the highs expected to reach the upper 80's to low 90's by Friday, then "climb into" the mid to upper 90's for the weekend, and a possibility of reaching the 100-110 degree range by early next week WOW! Current conditions for 6/26-mostly cloudy (scattered Cirrus, Cirrostratus, Altocumulus and Cumulus), the haze is light to moderate with little or no air movement. It is first from the North at 0-2 mph, then the SE at 2 mph, wind gust: out of the NNW to 11 mph, humidity 82%, dew point 53°, current snow level is near 8000', observation time temperature was 54°, and the barometric pressure 29.89" and rising.

The amount shown, was recorded yesterday as a result of intermittent showers throughout most of the day. Mid afternoon weather for 6/27-mostly cloudy (scattered Cirrus, Altocumulus, and Cumulus), temperatures are in the upper 70's to low 80's, BP 30.13"R along with very light air movement from the NW. Although the upper level low continued yesterday to spin SW of the Northern Queen Charlottes {it has since then moved SW from its previous position to well West of the Queen Charlottes according to the Canadian model}, and was responsible for the cool, showery weather the past few days, it will be prevented from tracking any closer toward WA as strong high pressure both at the surface (according to both the GFS and NAM models, this high pressure will migrate North over WA, OR, ID, and bring intense heat from the desert SW along with it) and aloft builds over WA and bring dry conditions and much warmer temperatures to the area today through the weekend, then more than likely peak by early next week. High temperatures during the period just mentioned should reach the upper 80's to low 90's today, the mid to upper 90's through the weekend and the likelihood of reaching the 100-110 dgree range by early next week. Current conditions for 6/28-partly cloudy (scattered Altocumulus and Cumulus), no precipitation during the overnight, the haze is light to moderate with little or no air movement. It is first from the North at 2-5 mph, then the South at 1 mph, wind puff: out of the NNE to 9 mph, humidity 70% (yesterday, the reading was 90%), dew point 58°, current freezing level is near 13,000' [yesterday, it was near 10,000'], observation time temperature was 58°, and the barometric pressure 30.20" and rising. |

Mid afternoon weather for 6/28-partly cloudy (scattered Cirrus, Cirrostratus, Cumulus, and Cumulus Congestus-to the NW), temperatures are in the upper 80's to low 90's, BP 30.00"F along with light air movement first from the East, then the South. Little change since yesterday as far as heat and high temperatures are concerned. Today and tomorrow's high temperatures should reach the mid to upper 90's with the warmest period occurring early next week as temperatures have a probability of reaching the 100-110 degree range. It is believed that these high temperatures will be brought about by a "major pattern change" in which-according to the GFS and NAM models-the surface high pressure will migrate North over ID, Eastern WA/OR and bring the intense heat from the desert SW along with it thus forcing the storm track well to the North of WA. The only blemish is a chance for "scattered showers and thunderstorms" today, which may produce "gusty winds, hail, and frequent lightening". As a case in point, one model is currently showing moderate sized bands of precipitation moving SW to NE over the Eastern third of WA several of which contain pockets of moderate to intense precipitation. Current conditions for 6/29-mostly overcast, no precipitation during the overnight, the haze is light to moderate with little or no air movement. It is first from the WNW at 3-5 mph, then the NE at 3 mph, wind gust: out of the NW to 12 mph, humidity 62%, dew point 63°, current freezing level is near 12,500', observation time temperature was 67°, and the barometric pressure 30.02" and falling. |

The amount shown is the most precipitation ever recorded since this observer began keeping records in 2009! Mid afternoon weather for 6/29-for a relative brief period of time, it was partly cloudy before a second "cell" moved over the area and brought additional lightening, thunder and rain though not like the downpour earlier in the day! As a result, high temperatures dropped from the upper 70's and low 80's to the mid 70's in a relative short period of time. BP was 29.98" along with calm winds. Current conditions for 6/30-clear skies, no additional precipitation during the overnight, the haze is moderate to bad with little or no air movement. It is first from the WNW at 6-10 mph, then the SE at 1 mph, wind gust: out of the WNW to 14 mph, humidity 73%, dew point 63°, current freezing level is near 14,500' [yesterday, it was near 12,500'], observation time temperature was 61°, and the barometric pressure 30.02" and falling. |

The current partly "cloudiness" is the result of a small cell moving North from The Dalles that should eventually turn NE. Whether or not any precipitation is received from this cell remains to be seen. Mid afternoon weather for 6/30-what a contrast from yesterday (an hour of heavy rain followed by a second cell that brought additional lightening, thunder and rain) to partly cloudy (scattered Cumulus) and very warm temperatures. Temperatures are in the mid to upper 90's, BP 29.88"F along with light air movement first from the East, then the South. Current conditions for 7/01-partly cloudy (scattered Cirrus, Altostratus and Cumulus), no precipitation during the overnight, the haze is moderate to bad with little or no air movement. It is first from the North at 2 mph, then the SE at 2 mph, wind gust: out of the NNW to 10 mph, humidity 60%, dew point 61°, current freezing level is near 14,500', observation time temperature was 70°, and the barometric pressure 29.98" and falling. Here are some interesting EOM stats for JUNE- 1) total rainfall: 1.60"-or about 203% of average. This also contributed to lowering the rain deficit of 0.89" in May, to 0.08" for June. 2) number of days with no precipitation: 19, 3) high BP: 30.20" on 6/28, 4) low BP: 29.58" on 6/24, 5) date with low BP and no precipitation: 29.79" on 6/11, 6) date with high BP and precipitation: 30.10" on 6/27 (0.09"), 7) average BP: 29.96", 8) average morning temperature-a) official minimum: 57°, b) normal low: 53.5°, c) digital: 58.2°, 9) low morning temperature-a) official minimum: 50° on 6/15, b) digital: 51.1° on 6/15, 10) high morning temperature-a) official maximum: 68° on 6/07, b) digital: 69.4° on 6/07, 11) average afternoon temperature-a) official maximum: 81.4°, b) normal high: 81.2°, c) digital: 79.2°, 12) low afternoon temperature-a) official minimum: 67° on 6/20, b) digital: 64.2° on 6/18, 13) high afternoon temperature-a) official maximum: 97° on 6/30, b) digital: 96.6° on 6/30 |

Mid afternoon weather for 7/02-clear skies (except for widely scattered Cumulus and what appeared to be high level smoke from the SW to NE) and very warm. Temperatures reached the low 100 degree range-and likely set a new record as the official high temperature was 106° which eclipsed the old record of 101° on this day in 1967! The BP was 29.80F along with light air movement first from the East, then the South. Even though many agencies are saying that the high temperatures will "cool into the 90's today in Eastern WA, this observer respectfully disagrees. Because the current freezing level is only slightly lower (15,500') than yesterday's level (16,000'), why should there be any difference from yesterday's high temperatures? This question begs an answer. Although the strong high pressure at the surface-now centered over North central NV-and aloft is already in the process of breaking down, or weakening, it is believed to be still strong enough to sustain high temperatures for one more afternoon. It is believed therefore, that the high temperatures today will reach the mid to upper 90's with a chance of nudging the low 100 degree range. However, by sometime later today, all three models-GFS, NAM, and Canadian-are indicating that the surface high pressure will "shrink" in size over South western NV-near Lake Tahoe-and the high pressure aloft should flatten to some extent. Current conditions for 7/03-clear skies, no precipitation in the last 24, the haze is light to moderate along with some nice air movement. It is from the West at 6-7 mph, then the NW at 5 mph, wind gust: out of the West to 25 mph, humidity 32%, dew point 47° {yesterday, the readings were 55% and 62° respectively}, current freezing level is near 15,500', observation time temperature was 73°, and the barometric pressure 29.97" and rising. |

Mid afternoon weather for 7/05-clear skies (except for some scattered Cumulus from the SW to the South) on a pleasant summer afternoon. Temperatures are in the mid 80's, BP 29.75"F along with nice air movement from the NW. It appears that today will be a transition from the cool and windy conditions of the past few days to one of continuous dry conditions and "seasonable warmth" in Eastern WA through at least the weekend (though not as HOT as last Tuesday-7/02-when the official high temperature reached 106°!). High temperatures for both today and tomorrow should reach the upper 80's to low 90's. Current conditions for 7/06-clear skies (except for scattered Cumulus toward the East and SW), no precipitation in the last 24, the haze is moderate with little or no air movement compared to earlier this morning. It was first from the West at 4-6 mph, then the NW at 7 mph, wind gust: out of the WNW to 16 mph, humidity 46%, dew point 47°, current freezing level is near 12,500', the observation time temperature was 62°, and the barometric pressure 29.87" and falling. |

Mid afternoon weather for 7/06-partly cloudy (scattered Cumulus), temperatures are in the low to mid 90's-which is still about 5-10 degrees above normal-BP 29.73"F along with light air movement first from the East, then the South, and finally the SW. Even though one model shows a trough moving inland over WA and NW OR, it appears that the region SE of its SE boundary (Southern ID, Northern NV and CA as well as Southern OR) will be warmer while Eastern WA will continue to be dry and "seasonably warm" with high temperatures likely to reach the mid to upper 80's today. In the meantime, another model is showing a threat of thunderstorm activity for tonight through tomorrow (7P-7A). The greatest impact-at least for this area-would be "gusty winds" and "lightening". There are indications however, of a brief warming trend early this week as high temperatures-after today-are likely to reach the low to mid 90's. This will be followed by a cooling trend that should commence by mid week and persist through the end of the work week. Current conditions for 7/07-clear skies (except for widely scattered Cirrus, Altocumulus and Cumulus), no precipitation in the last 24, the haze is moderate to bad with little or no air movement. It is first from the ESE at 2-8 mph, then the South at 3 mph, wind puff: out of the SE to 9 mph, humidity 56%, dew point 55° {yesterday, the readings were 46% and 47° respectively}, current freezing level is near 10,500' [yesterday it was near 12,500'], observation time temperature was 61°, and the barometric pressure 29.89" and rising.

Mid afternoon weather for 7/07-overcast, temperatures are in the low to mid 90's which-as was the case yesterday-is still 5-10 degrees above normal. BP is 29.71"F along with light air movement from the NE. Although Eastern WA should continue to be dry and seasonably warm, all three models (GFS, NAM, and Canadian) show a trough over WA and OR along with a "disturbance" over SE BC with some of its energy extending SW (and moving East) over NE WA. As a result, another model is showing the potential for thunderstorm activity-along with "isolated lightening" and "brief downpours"-in the area just mentioned. Otherwise, there are indications of a brief warming trend today and tomorrow with high temperatures likely to reach the low to mid 90's. This will be followed by a cooling trend that should commence by mid week and persist through the end of the work week before yet another warming trend is projected to arrive and remain through the weekend. Current conditions for 7/08-clear skies (except for widely scattered Cumulus to the East, North, and from the SW to the South), no precipitation in the last 24, the haze is still moderate to bad along with some air movement. It is first from the West at 2 mph, then the NW at 6 mph, wind gust: out of the WNW to 14 mph, humidity 43% (yesterday, the reading was 56%), dew point 51°, current freezing level is near 12,000' [yesterday, it was near 10,500], observation time temperature was 65°, and the barometric pressure 29.89" and rising. |

Mid afternoon weather for 7/09-mostly clear (widely scattered Cumulus), temperatures are in the mid 90's (which is still 8-10 degrees above normal), BP 29.91R along with light air movement from the South. Earlier in the week, it was mentioned that Eastern WA would continue to be dry and seasonably warm as a result of a brief warming trend with high temperatures likely to reach the low to mid 90's. The warmest of the two days-Tuesday-reached an official high of 97°! This warming trend was to be followed by a cooling trend that would commence sometime today and persist through the end of the work week due to a "dry cold front" that should bring sustained winds of 10-20 mph, and gusts up to 25 mph during the "afternoon and early evening hours" with its passage. High temperatures should reach the upper 80's to low 90's today and the mid to upper 80's tomorrow as a second dry cold front moves across the area with similar results-"breezy winds" and "dry conditions". Current conditions for 7/10-clear skies, no precipitation in the last 24 and the haze is light to moderate along with nice air movement. It is first from the WNW at 5-11 mph, then the NW at 5 mph, wind gust: out of the NW to 15 mph, humidity 42% {yesterday, the reading was 54%}, dew point 53°, current freezing level 13,500', observation time temperature 65°, and the barometric pressure 29.89" and rising. |

Mid afternoon weather for 7/12-overcast with light sprinkles on or near Burch Mountain to the North. Temperatures are in the mid to upper 70's (which is a few degrees cooler than yesterday), BP 29.89F along with light air movement from the SW. Although a trough (with its southern boundary just off the OR/CA border)is keeping warmer air suppressed for the time being over Southern ID, NV and UT, it appears that Eastern WA will continue to experience dry conditions but warmer temperatures in comparison to the last two days when the "cooling trend" finally arrived on Thursday-instead of Wednesday-and remained through the end of the work week. High temperature for these two days were 85°, and 78° {or, about 2 and 9 degrees below normal respecively}. However, it looks as though this area will, one again, experience a rebound to very warm temperatures by early next week with highs likely to reach the mid to upper 90's and possibly nudging 100 degrees. Current conditions for 7/13-clear skies (except for scattered Cumulus to the North and SW), no precipitation in the last 24, the haze is light to moderate with little or no air movement. It is first from the West at 7-10 mph, then the NW at 5 mph, wind gust: out of the WNW to 15 mph, humidity 35%, dew point 42°, current freezing level is near 10,500' [yesterday, it was near 8500'], observation time temperature was 56°, and the barometric pressure 30.07" and rising. |

Mid afternoon weather for 7/13-clear skies, BP 30.03F, temperatures are in the low to mid 80's along with a nice refreshing breeze first from the East, then the SE and finally the South. A "broad trough", or the NPJ, is flowing East over the southern Provinces (near the borders of WA, ID and Western MT) of BC, Alberta and Saskatchewan that should keep low pressure over central BC and at the same time allow warmer air (that yesterday was over Southern ID, NV and UT) to "expand" NW over Northern CA, Eastern OR/WA, and Western MT. As a result, this area will experience warmer temperatures today with the highs likely to reach the mid to upper 80's and possibly the low 90's. This "warming" trend should continue at least through early this week with high temperatures reaching the mid to upper 90's along with a chance of nudging 100 degrees during this period. Looking ahead, the next "eight to fourteen days" are likely to feature above normal high temperatures and below normal precipitation. Current conditions for 7/14-clear skies, no precipitation in the last 24, the haze is light to moderate with little or no air movement. It is first from the West at 3-4 mph, then the South at 3 mph, wind gust: out of the WNW to 13 mph, humidity 52%, dew point 49° {yesterday, the readings were 35% and 42° respectively}, current freezing level is near 12,500' [yesterday, it was near 10,500'], observation time temperature was 56°, and the barometric pressure 30.06" and rising. |

Mid afternoon weather for 7/14-clear skies (except for widely scattered Cirrus-that were just visible-from the SW to the West), temperatures were in the upper 80's to low 90's, BP 29.83"F along with light air movement first from the East, then much stronger air movement from the SW as a result of what was believed to be a weak front moving through the area. While one model shows very dry air in place over OR, and most of CA, WA, ID and Western MT, a large area of high pressure remains over the Pacific and West of the WA/OR border but continues to expand NW over Eastern WA/OR, ID and MT. As a result, the highs in Eastern WA should reach the upper 80's to low 90's today and tomorrow. In addition, this "heat" should continue through the end of the work week (although there is the likelihood that "fast moving" and "widely scattered" thunderstorms will move through the area "Tuesday evening though Wednesday afternoon" that should result in "numerous" dry lightening "strikes" but little, if any, precipitation) with high temperatures likely to reach the mid to upper 90's and quite possibly the low 100's. Current conditions for 7/15-clear skies, no precipitation in the last 24, the haze is moderate with little or no air movement. It is first from the West at 2-4 mph, then the North at 3 mph, wind gust: out of the West to 17 mph, humidity 36%, dew point 43° {yesterday, the readings were 52% and 49° respectively}, current freezing level is near 13,500' [yesterday, it was near 12,500'], observation time temperature was 62°, and the barometric pressure 29.97" and rising. |

Mid afternoon weather for 7/16-mostly cloudy (scattered Cirrus, Cirrostratus, Altocumulus and widely scattered Cumulus), temperatures are in the upper 80's to low 90's, BP 29.79F along with light air movement from several directions including the East, NE, South, SW and finally the North. Yesterday's prediction for fast moving and widely scattered thunderstorms that should produce numerous lightening "strikes" finally came to fruition during late last evening or early this morning with lightening (one bolt lit up my bedroom!), thunder and a brief downpour. This storm has since moved North of the area over Okanogan and extreme NE Grant counties where a severe weather alert was posted {as one model is showing low pressure near central WA and another over SW WA} for not only lightening and thunder, but also "quarter sized hail" and "extremely heavy downpours". With the passage of this storm however, temperatures should recover rather quickly today with highs likely to reach the mid to upper 80's. This heat will become even more evident by the end of the work week through the weekend as high temperatures during this period should reach the mid to upper 90's and quite possibly the low 100's. Current conditions for 7/17-mostly clear (scattered Altocumulus and Cumulus in addition to a relative small area of Cirrus toward the North), the haze is moderate with little or no air movement. It is first from the North at 1-2 mph, then the South at 1 mph, wind gust: out of the NNW to 16 mph, humidity 69%, dew point 59° {yesterday, the readings were 38%, and 46° respectively}, current freezing level is near 11,500' [yesterday, it was near 13,500'], observation time temperature was 67°, and the barometric pressure 29.88" and falling. |

Mid afternoon weather for 7/18-mostly clear (except for some widely scattered Cumulus), and very warm. Temperatures are in the mid to upper 90's, BP 29.95"F along with slight air movement from the NE. Other than low pressure off the OR coast (which should remain stationary due to a large area of high pressure centered over North eastern NV), several models show no significant system over the Pacific that would affect this area for the time being until perhaps by mid week of next week. As a result, today through at least the weekend-if not longer-should be very warm-as this heat expands "Northward". High temperatures during this period, will reach the mid to upper 90's and quite possibly the low 100's. Current conditions for 7/19-clear skies, no precipitation in the last 24, the haze is moderate to bad with little or no air movement. It is first from the North at 3-5 mph, then the SE at 3 mph, wind gust: out of the North to 14 mph, humidity 41%, dew point 51°, current freezing level is near 15,000' [yesterday, it was near 14,000'], observation time temperature was 68°, and the barometric pressure 30.03" and falling. |

Mid afternoon weather for 7/19-clear skies and HOT- plus a splendid view of Glacier Peak to the NW! Temperatures are in the upper 90's to low 100's, BP 29.83"F along with refreshing light air movement first from the East, then the SE, South, SW, and finally the NE. There should be little-if any-change from yesterday's weather today as strong high pressure (centered over Western NV near Lake Tahoe) has pushed the storm track well North of WA over Southern AK and the Yukon which should result in another day of very warm temperatures for Eastern WA/OR. This trend should continue through tomorrow into early next week. High temperatures during this period should, once again, reach the mid to upper 90's and quite likely the low 100's. Interestingly, yesterday's low pressure that was spinning off the OR coast-and should have remained stationary-, has since moved West by SW well off the NW coast of CA according to both the GFS and NAM models. Current conditions for 7/20-clear skies, no precipitation in the past 24, the haze is moderate along with light air movement. It is first from the West at 4-6 mph, then the NW at 5 mph, wind gust: out of the WNW to 21 mph, humidity 24%, dew point 43° {yesterday, the readings were 41% and 51° respectively}, current freezing level is near 15,500', BP 29.91" and falling. |

Mid afternoon weather for 7/20-clear skies (except for what appeared to be scattered "smoke" as a result of a fire on the North shore of Lake Wenatchee), temperatures are in the upper 90's to low 100's, BP 29.75"F along with refreshing air movement first from the NE, then the NW. Strong high pressure centered over the Pacific and West of Northern CA-near the Bay area-should result in another day of very warm high temperatures-mid to upper 90's-(but with a potential for "gusty winds" this afternoon as a result of a "weak system") for two more days in Eastern WA/OR. Looking ahead, there are indications that a cooling trend appears to be in the offing and should commence by mid week and persist through the first half of the weekend. Although the freezing level will drop from a maximum level of 15,500' on Tuesday to a minimum level of 11,000' by Saturday, the high temperatures will still be warm (but not as warm as the past few days!) and should reach the upper 80's to low 90's. Current conditions for 7/21-clear skies, no precipitation in the last 24 {there has been only two measurable rain events so far}, the haze continues to be moderate with little air movement. It is first from the West at 4-6 mph, then the NW at 5 mph, wind gust: out of the WNW to 21 mph, humidity 24%, dew point 42°, current freezing level is near 15,000', observation time temperature was 68°, and the barometric pressure 29.79" and falling. |

Mid afternoon weather for 7/21-clear skies (except for scattered smoke), temperatures are in the upper 90's to low 100's, BP 29.66"F along with light air movement from the NW. It seems as though a correction is in order. Yesterday, it was mentioned that today and tomorrow would feature very warm temperatures before a cooling trend would commence by mid week and persist through the first half of the weekend. It now appears that these very warm temperatures will continue through most of the work week and that the cooling trend-mentioned above-should now commence by the end of the work week and remain through the weekend. In the meantime, while strong high pressure is centered just West of Northern CA, and another very warm day is likely in Eastern WA (as high temperatures should reach the low to mid 90's along with the likelihood of "gusty winds"), the coastal areas of WA will be cooler. As for the windy conditions in this area, it is believed that the cause is the result of air flowing around low pressure well off the WA coast and over the apex of a high pressure ridge NW of the OR coast. Current conditions for 7/22-clear skies, no precipitation in the last 24, the haze continues to be moderate though with some nice air movement. It is first from the WNW at 7-18 mph, then the NW at 7 mph, wind gust: out of the NW to 20 mph, humidity 31%, dew point 47° {yesterday, the readings were 24% and 42° respectively}, current freezing level is near 15,000', observation time temperature was 72°, and the barometric pressure 29.89" and falling. |

Mid afternoon weather for 7/22-clear skies, temperatures are in the mid to upper 90's, BP 29.78"F along with light, refreshing air movement first from the East, then the West, and finally, a stronger sustained breeze from the North. As was mentioned yesterday, these very warm temperatures should continue through most of the week in Eastern WA as high pressure over OR, ID, MT, WY, and WA has strengthened somewhat since yesterday and should, therefore, keep any wind to a minimum (not-by comparison-like yesterday's "gusty winds"). High temperatures should reach the mid to upper 90's with a possibility of nudging the low 100's during this period (mentioned above). However, the GFS, NAM and Canadian models are showing the likelihood of a cooling trend that will likely commence by the end of the work week and persist through at least the weekend. Current conditions for 7/23-clear skies (except for a few Cirrus to the South), no precipitation in the last 24, the haze is moderate with little or no air movement. It is first from the West at 0-3 mph, then the SW at 1 mph, wind gust: out of the WNW to 18 mph, humidity 47%, dew point 55° {yesterday, the readings were 31% and 47° respectively}, current freezing level is near 15,000', observation time temperature was 65°, and the barometric pressure 29.95" and rising. |

Mid afternoon weather for 7/23-mostly clear skies (Cirrus and Cirrostratus extending from the SW to the SE, and scattered "smoke" from the NW to the SW), and very warm. Temperatures are in the upper 90's to low 100's, BP 29.79"R along with refreshing, light air movement first from the SE, then the South. Today should be almost a carbon copy of yesterday's weather with very warm temperatures continuing today and tomorrow in Eastern WA as a result of a dominant high pressure (centered over Southern CA near the Baja border) over OR, ID, MT, WY, and WA. Highs today and tomorrow should, once again, reach the mid to upper 90's with a chance of nudging the low 100's. The only chink in the armor will be "wind in the morning", then becoming "light" in the afternoon. However, the GFS, NAM, and the Canadian models continue to show the likelihood of a cooling trend to commence by Saturday and persist through early next week. Current conditions for 7/24-clear skies (except for widely scattered Cirrus), no precipitation in the last 24, the haze contines to be moderate with little or no air movement. It is first from the West at 4-11 mph, then the SE at 3 mph, wind gust: out of the WNW to 18 mph, humidity 42%, dew point 54°, current freezing level is near 14,500', observation time temperature was 68°, and the barometric pressure 29.91" and rising. |

Mid afternoon weather for 7/24-mostly clear (scattered Cirrus, Cirrostratus, and denser Cirrostratus), and very warm. Temperatures are, once again in the upper 90's to low 100's (today's official high of 102° came within 4 degrees of tying the record high of 106° on this day back in 1994!), BP 29.79"R along with refreshing, light air movement first from the East, then the SE and finally the South. Today should be a carbon copy of ysterday with very warm temperatures as high pressure-now centered over SE CA near Las Vegas-remains over OR, ID, MT, WY, and WA. High temperatures should, once again, reach the mid to upper 90's with yet another chance of nudging the low 100's. There are indications however, that this ridge of high pressure will begin to weaken tomorrow and low pressure-currently just West of the Alexander Archipelago-will be a factor toward the commencement of a cooling trend by Saturday that should now persist through much of next week according to the Canadian and ECMWF models. Current conditions for 7/25-clear skies, no precipitation in the last 24, the haze is moderate to bad with little or no air movement. It is first from the WNW at 2-8 mph, then the South at 2 mph, wind gust: out of the NW to 18 mph, humidity 45%, dew point 52°, current freezing level is near 14,500', observation time temperature was 70°-which is 12 degrees above normal-, and the barometric pressure 29.95" and rising. |

Mid afternoon weather for 7/25-clear skies and very warm. Temperatures are in the upper 90's to low 100's (the official high of 103° today, came within 2 degrees of tying the record of 105° on this day way back in 1962!), BP 29.85"R along with light air movement from the SW. It appears as though today will feature another carbon copy of yesterday with continued dry conditions, very warm temperatures and the prospect for "windy conditions this afternoon through the nighttime hours" as a result of "a weak cold front moving through the area today". High temperatures should reach the mid to upper 90's with the likelihood of nudging the low 100's as high pressure-though it has begun to weaken-remains over WA. In the meantime, the "cooling trend"-that has been mentioned for the past five days-looks as though it will finally commence somtime this evening and persist through early next week. As a result, high temperatures during this period, should be "closer to normal" which, for Eastern WA would be the upper 80's to low 90's. Current conditions for 7/26-clear skies (except for some widely scattered clouds to the North), no precipitation in the last 24, the haze is moderate with little or no air movement. It is first from the West at 4-6 mph, then the SE at 4 mph, wind gust: out of the WNW to 18 mph, humidity 27%, dew point 44° {yesterday the readings were 45% and 52° respectively}, current freezing level is near 15,000', observation time temperature was 61°, and the barometric pressure 30.00" and rising.

Mid afternoon weather for 7/26-clear skies and very warm. Temperatures are, once again, in the upper 90's to low 100's (the official high of 101° came within 3.1 dgrees of tying the recored of 104.1° on this day in 1998!), BP 29.78"R along with light air movement from the NW. Although today will be sunny and warm in Eastern WA with high temperatures likely to reach the low to mid 90's (there is the prospect of another wind event as "locally breezy winds will develop during the late afternoon or early evening" as one model is showing a cold front tracking SE over SE BC and NW WA), low pressure over extreme Eastern central BC-near the Northern Canadian Rockies-looks to be partly responsible for bringing cooler air into Western WA and NW OR. In addition, the "cooling trend" that was to commence last evening is underway and should persist through much of next week. As a result, the high temperatures should be "closer to normal" which, for Eastern WA would be the upper 80's to low 90's. Current conditions for 7/27-clear skies (except for bands of Cirrus from the West to the NE), no precipitation in the last 24, the haze is light to moderate along with some nice air movement. It is first from the WNW at 4-5 mph, then the NW at 5 mph-it has since picked up somewhat-wind gust: out of the NW to 23 mph, humidity 24%, dew point 41°, current freezing level is near 13,000' [yesterday, it was near 15,000'], observation time temperature was 70°, and the barometric pressure 29.96" and rising. |

Mid afternoon weather for 7/27-clear skies (except for a large smoke cloud from the South to the SE as a result of a fire on or near Colockum Pass South of
Wenatchee), temperatures are in the upper 80's to low 90's, BP 29.80"F along with some nice air movement first from the NW, then the West. Although weak high pressure-over the Pacific but well SW of WA-will bring continued dry conditions to the area, a break from the heat of the past ten days appears to be in order and for much of the upcoming week due to the probability of a storm which should "slowly move through the region this week". In addition, both the "instability" and "moisture" associated with the storm is likely to cause "thunderstorms to develop during the week" with the best chance of precipitation from mid week to the end of the work week. Current conditions for 7/28-clear skies (except for an immense fire cloud from the SW to the SE and a few widely scattered Cumulus to the North and NE), no precipitation in the last 24, the haze is light to moderate with little or no air movement. It is first from the WNW at 5-11 mph, then the NW at 6 mph, wind gust: out of the NW to 20 mph, humidity 26% dew point 40°, current freezing level is near 11,500' [yesterday, it was near 13,000'], observation time temperature was 65°, and the barometric pressure 29.86" and falling.

Mid afternoon weather for 7/28-clear skies (except for an immense smoke cloud from the SW to the SE as well as a very impressive cloud interspersed with the smoke cloud), and warm. Temperatures are in the upper 80's to low 90's, BP 29.72"R along with nice air movement from the NW. Another dry day is in store for Eastern WA as well as close to normal high temperatures which, for this area, would be in the upper 80's to low 90's. A storm that should slowly move through the region this week {although one model shows low pressure tracking SE-just South of WA-over NW OR by mid week, South of The Dalles by the following day before turning NE over extreme South eastern WA by Friday}, along with the "instability" and "moisture" associated with it, is likely to cause thunderstorms to develop during the week with the best chance of precipitation from mid week through the end of the work week. Current conditions for 7/29-clear skies (except for scattered Cirrus/smoke and widely scattered Cumulus), no precipitation in the last 24, the haze is moderate to bad with little or no air movement. It is first from the WNW at 4-6 mph, then the SE at 3 mph, wind gust: out of the NW to 16 mph, humidity 53%, dew point 52° {yesterday, the readings were 26% and 40° respectively}, current freezing level is near 10,500' [yesterday, it was near 11,500'], observation time temperature was 60°, and the barometric pressure 29.88" and rising. |

Mid afternoon weather for 7/29-apart from an immense area of smoke that extends from the West to the SE and a spur from the SE to the East, it appears that it is partly cloudy (scattered Cumulus). Temperatures are in the upper 80's to low 90's, BP 29.77"R along with light air movement first from the East, then the SE, and finally the South. Although today and tomorrow will continue to feature dry conditions with high temperatures likely to reach the mid to upper 80's and possibly the low 90's, a change is forthcoming as a storm-the same one that has been mentioned for the last two days-should slowly move through the region this week (although one model continues to show it tracking SE-just South of WA-over NW OR, then East near The Dalles by mid week before turning NE over SE WA, the Northern panhandle of ID and into NW MT by Friday instead of extreme South eastern WA as was previously thought) and, with the "instability" and "mositure" associated with it thunderstorms are likely to develop during the week with the best chance for precipitation-at least in this area anyway-near the end of the work week. Current conditions for 7/30-apart from the hazy smokey skies, it appears to be mostly clear (scattered Altocumulus and Altocumulus Undulatus from the NW to the NE), no precipitation in the last 24, the haze/smoke is moderate to bad with little or no air movement. It is first from the WNW at 6-7 mph, then the South at 3 mph, wind gust: out of the NW to 14 mph, humidity 52%, dew point 54°, current freezing level is near 11,000', observation time temperature was 63°, and the barometric pressure 29.98" and rising. |

Mid afternoon weather for 7/30-apart from the "smoke" that is almost overhead and from the West to the SE, the sky appears to be mostly clear (except for widely scattered Cumulus to the North and NW). Temperatures are in the low to mid 90's, BP 29.93"R along with light air movement from the SE. Today appears as though it will stay dry and on the warm side with highs likely to reach the mid to upper 80's and possibily the low 90's. However, the high temperatures will cool to the low to mid 80's by tomorrow, and the upper 70's to low 80's for Friday and Saturday before rebounding early next week. These cooler temperatures are the result -and sounding like a stuck record-of a storm moving slowly through the region this week that should feature increased thunderstorm acivity "tonight with little rain and a potential for gusty winds". Interestingly, tomorrow should bring "widespread WET thunderstorms and the potential for brief heavy rain and hail". Although the "thunderstorm activity will linger into Saturday", their intensity should be on the wane. Current conditions for 7/31-mostly cloudy (scattered Cirrus and Altocumulus), no precipitation in the last 24, the haze/smoke is bad with little or no air movement. It is first from the WNW at 5-7 mph, then the North at 4 mph, wind gust: out of the North to 14 mph, humidity 51%, dew point 54°, current freezing level is near 11,000, observation time temperature was 64°, and the barometric pressure 30.05" and rising. |

Mid afternoon weather for 7/31-although we have overcast skies, virga was observed toward the East and South as well as brief, intermittent sprinkles. Temperatures are in the mid 80's, BP 29.89"R along with calm winds. Current conditions for 8/01-mostly overcast (Altocumulus and scattered Cirrus), no precipitation during the overnight, and the
air quality is moderate to bad with little or no air movement. It is first from the WNW at 2-5 mph, then the South at 3 mph, wind gust: out of the NW to 16 mph, humidity 57%, dew point 54°, current freezing level is near 10,500', observation time temperature was 60°, and the barometric pressure 29.91" and rising.

The amount shown was recorded last evening during the times indicated below. Mid afternoon weather for 8/01-overcast and very ominous from the East to the North. In addition, lightening was observed and thunder heard in the distance but, thus far, no rain has been recorded at this station. In the meantime, temperatures reached the mid to upper 80's, BP 29.77"F along with somewhat "breezy" winds. Last evening, we ate dinner in the carport and witnessed a spectacular display of lightening as well as a 7-10 minute downpour. The culprit responsible for this "wild weather" was a "potent" low pressure off the Northern OR coast and with its counterclockwise rotation brought moisture and instability to this area. Today, the likelihood of showers and or thunderstorms is the result of this same low pressure which has since moved from its previous position-mentioned above-and set up over Eastern WA.
With regards to the high temperatures, they should reach the mid to upper 70's (which, for this day in August, is about 10-14 degrees BELOW normal). In the meantime, the passage of this low pressure by sometime tomorrow should bring a return to summer with dry conditions and warmer temperatures by Sunday and persist through much of next week. Current conditions for 8/02-mostly overcast (Altocumulus, Cumulus along with scattered Cirrus and Cirrostratus), the smoke/haze is light to moderate with little or no air movement. It is first from the West at 3-6 mph, then the East at 2 mph, wind gust: out of the WNW to 18 mph, humidity 83% {yesterday, the reading was 57%}, dew point 57°, current freezing level is near 10,500', observation time temperature was 61°, and the barometric pressure 29.94" and rising. |

The amount shown was recorded yesterday at the time listed below. Mid afternoon weather for 8/02-mostly cloudy (scattered Cirrus, Cirrostratus, Altocumulus and Cumulus). Temperatures are in the upper 70's to low 80's {which is still about 6-10 degrees below normal}, BP 29.94"F along with cool, light air movement first from the North, then the West. Although at the present time it is mostly overcast, and gradually improving, it appears as though drier conditions and warmer temperatures are in store as the potent upper level low responsible for bringing the "recent inclement weather" has since commenced to weaken over Eastern WA due to high pressure West of the OR coast.
This high pressure should continue to strengthen and, as mentioned above, bring drier conditions and warmer temperatures theough early next week. High temperatures today are likely to reach the upper 70's to low 80's; tomorrow should be warmer with highs in the low to mid 80,s. Current conditions for 8/03-a nice improvement from overcast skies earlier this morning to partly cloudy (scattered Altocumulus, Cumulus and Cumulus Congestus), no precipitation during the overnight, the haze is light to moderate with little or no air movement. It is first from the North at 4-6 mph, then the East at 4 mph, wind gust: out of the North to 14 mph, humidity 63%, dew point 51° (yesterday, the readings were 83% and 57° respectively), current freezing level is near 10,500', observation time temperature was 61°, and the barometric pressure 30.04" and rising. |

Mid afternoon weather for 8/03-partly cloudy (scattered Altocumulus and Cumulus in addition to a few scattered Cumulus Congestus), temperatures are in the mid 80's, BP 29.96"F along with a cool, sustained light breeze-and gusts-first from the East, then the SE and finally the South. With the potent upper level low no longer influencing the weather in Eastern WA, and high pressure (still over the Pacific and West of the OR coast) continuing to strengthen for the "next couple of days", today will not only be dry, but also warmer than yesterday (mid 80's) with highs likely to reach the mid to upper 80's and a possibility of nudging the low 90's. The outlook through at least mid week appears to be a continuation of dry conditions and very warm temperatures as highs should reach the low to mid 90's with a chance of brushing the low 100's. Current conditions for 8/04-an increase of clouds since earlier this morning to partly cloudy (scattered Cumulus), no precipitation in the last 24, the haze is moderate; however, from the South to the SW the smoke is bad with little or no air movement. It is first from the WNW at 5-7 mph, then the SE at 2 mph, wind puff: out of the NW to 9 mph, humidity 65%, dew point 58°, current freezing level is near 11,000', observation time temperature was 60°, and the barometric pressure 30.01" and rising. |

The amount shown was recorded last evening at the time shown below. Mid afternoon weather for 8/04-from clear skies earlier this morning to mostly cloudy (Altocumulus and Cumulus), plus a few bolts of lightening were also observed to the North. Temperatures are in the upper 80's to low 90's, BP 29.86"F along with calm winds. Although yestereday's forecast for last evening called for "partly cloudy skies and isolated showers and thunderstorms", the chance of precipitation was 20%...yah, only 20%! So, once again, we ate dinner in the carport and witnessed another spectacular display of lightening as well as several minutes of heavy rain though not of the intensity that was brought to the area three days ago (8/02) due to a potent upper level low. The culprit responsible for this "wild weather" last evening, was an area of low pressure over Southern BC which has since moved East by NE over the central Alberta/Saskatchewan border.In the meantime, high pressure over the Pacific {West of WA}, should continue to strengthen today, and as a result bring dry conditions and warmer temperatures through at least mid week. Highs today should reach the low to mid 90's and the mid to upper 90's by tomorrow with a chance of nudging 100 degrees. Current conditions for 8/05-mostly clear (scattered Cumulus), no precipitation in the last 24, the haze/smoke is light to moderate with little or no air movement. It is first from the West at 3-5 mph, then the NE to 4 mph, wind gust: out of the WNW to 11 mph, humidity 67%, dew point 60°, current freezing level is near 12,500' [yesterday, it was near 11,000'], observation time temperature was 62°, and the barometric pressure 29.96" and falling. |

Mid afternoon weather for 8/06-mostly clear (widely scattered Altocumulus, Cumulus and another smoke cloud that extends from the SW to the SE), temperatures are in the mid 90's-the official high was 97° which is now about 10 degrees ABOVE normal when just a few days ago [8/03], it was 7-10 degrees BELOW normal-BP 29.79"F, along with light air movement from the South. Although the weather pattern over Eastern WA should continue warm and dry, because of strong high pressure over Northern UT, it appears that today will be the warmest day of the week. Highs should reach the mid to upper 90's along with a chance of nudging 100 degrees. However, there are indications that this strong ridge of high pressure will begin to weaken somewhat and simultaneously move East during the next few days thereby allowing the warmest "heat" to move over Eastern WA. In addition, there are signs of a cooling trend as low pressure currently off the Northern coast of CA begins to move North toward WA {according to the GFS, NAM, and Canadian models} and with it the "potential for thunderstorms Friday through Monday", the possibility of "locally heavy rain", and an "increase in lightening activity". Incidentally, the chance of precipitation is 30%!! Current conditions for 8/07-clear skies (except for widely scattered Cirrus, Cirrostratus, and a smoke cloud from the South to the SE), no precipitation in the last 24, the haze/smoke is light to moderate with little or no air movement. It is first from the WNW at 0-1 mph, then the South at 3 mph, wind gust: out of the NW to 13 mph, humidity 39%, dew point 48°, current freezing level is near 14,000', observation time temperature was 61°, and the barometric pressure 29.88" and falling.

The amount shown was recorded late last evening at the times given below. Mid afternoon weather for 8/09-partly cloudy (the "smoke cloud" continues to extend from the SW to the SE as well as scattered Cirrus, Cirrostratus and Cumulus), high temperatures were in the mid to upper 90's-though the official high temperature was 98°, or 10 degrees above normal, it was still about 6 degrees from tying the record high on this date way back in 1958-BP 29.69"F along with minimal air movement from the SE. WOW! what a spectacular display of lightening as well as several minutes of heavy rain late last evening. The culprit responsible for another round of "wild weather" is the same upper level low that had been spinning for most of the week off the Northern CA coast and is now over South western OR according to the GFS, NAM, and UW models. As a result, this upper level low is likely to produce continued lightening activity, the possibility of "gusty winds", and "periods of heavy rain" today and tomorrow. Highs should reach the low to mid 90's. Current conditions for 8/10-mostly clear (except for smoke from a new fire SE of
Wenatchee and scattered Cumulus), no precipitation in the last 24, the haze/smoke is moderate to bad with little or no air movement. It is first from the West at 4-5 mph, then the North at 5 mph, wind gust: out of the WNW to 27 mph, humidity 59%, dew point 63°, current freezing level is near 12,000', observation time temperature was 69°, and the barometric pressure 29.91" and rising. |

Unfortunately, this observer did not note what time last evening's event began. Mid afternoon weather for 8/10-aside from smoke over the area, it appears as though the skies are partly cloudy (scattered Cirrus, Cirrostratus and Cumulus), temperatures are in the low to mid 90's, BP 29.78"R along with minimal air movement from the NW. Four days ago, it was stated that low pressure-then off the coast of Northern CA-was to bring the potential for thunderstorms Friday through Monday, along with the possibility of locally heavy rain, an increase in lightening acivity and "gusty winds". Well, this area has experienced these distinctive characteristics for the past two evenings with yet another spectacular display of lightening and gusty winds. In the meantime, this slow moving upper level low has since moved North off the NW coast of OR and is bringing with it the likelihood of lightening activity, gusty winds and periods of heavy rain by sometime this afternoon or evening. Current conditions for 8/11-much improved air quality since yesterday afternoon with partly cloudy skies (scattered Cirrus, widely scattered Cumulus and a small area of Altocumulus toward the East), no precipitation during the overnight, the smoke/haze is light to moderate with very little air movement. It is first from the West at 4-10 mph, then the South at 3 mph, wind gust: out of the West to 19 mph, humidity 69% {yesterday, the reading was 59%}, dew point 60°, current freezing level is near 11,000' [yesterday, it was near 12,000'], observation time temperature was 64°, and the barometric pressure 29.98" and rising. |

The amount shown was recorded yesterday afternoon. Mid afternoon weather for 8/11-mostly cloudy (scattered Cirrus, Cirrostratus, Cumulus and Cumulus Congestus) and ominous. Temperatures are in the mid to upper 80's, BP 29.83"R along with minimal air movement from the SE. Yesterday's low pressure that was off the central coast of OR has since continued to migrate North and away from WA to the central SW coast of Vancouver Island and, as a result the "chance of storms should shift North of Seattle into BC". Because of this migration, it would appear that the worst is over in Eastern WA as far as showers and thunderstorms are concerned although there is still a "20% chance". With the passage of this low pressure, warmer temperatures and dry conditions will return as high pressure establishes itself over WA for the next few days, and, during this period, the highs should reach the low to mid 90's. Current conditions for 8/12-mostly clear (scattered Cumulus), no precipitation during the ovenight, the haze/smoke is light to moderate with little or no air movement at the present time. It is first from the WNW at 7-9 mph, then the South at 3 mph, wind gust: out of the NW to 18 mph, humidity 68%, dew point 58°, current freezing level is near 11,000' observation time temperature was 60°, and the barometric pressure 29.96" and rising. |

Mid afternoon weather for 8/12-mostly clear (except for scattered Cirrus and Cirrostratus from the SW to the SE, and Cumulus from the North to the West), temperatures are in the upper 80's to low 90's, BP 29.83"R along with minimal air movement from the SW. Although changes will occur-especially in Western WA-as a weak cold front ("first of the season") along with a strong low pressure system, moves toward the WA coast and could produce coastal showers late tomorrow night into Thursday. However, at this point in time, it looks as though mnost of the energy associated with this system will move NE into BC. By way of contrast, with yesterday's low pressure no longer influencing WA, warmer temperatures and dry conditions will dominate the weather picture in Eastern WA as high pressure is established through tomorrow. As a result high temperatures should reach the low to mid 90's both days. Current conditions for 8/13-partly cloudy (scattered Cirrus), no precipitation in the last 24, the haze/smoke is light to moderate with little or no air movement. It is first from the North at 8 mph, then the SE at 2 mph, wind gust: out of the North to 16 mph, humidity 61%, dew point 57°, current freezing level is near 13,000' [yesterday, it was near 11,000], observation time temperature was 62°, and the barometric pressure 29.99" and rising. |

Mid afternoon weather for 8/13-clear skies (except for scattered Cirrus and what appears to be smoke), temperatures are in the low to mid 90's, BP 29.86"R along with calm winds. Although Eastern WA should experience another day of warm temperatures, the clouds over the area are believed to be associated with that strong system over the Pacific (which, by the way, has moved further East toward WA) though most of its energy will track NE into BC according to both the GFS and NAM models. In addition, after today, the freezing level will commence a gradual decline and reach a minimum level of near 11,000' by the first part of the weekend which, all in all, points to a slight cooling trend. In response, high temperatures will also gradually decline with highs likely to reach the upper 80's to low 90's today, but only the low to mid 80's by Saturday. Current conditions for 8/14-mostly cloudy (scattered Cirrus, Cirrostratus, and Altocumulus), no precipitation in the last 24, the haze/smoke is moderate with little or no air movement. It is first from the North at 1-3 mph, then the South at 2 mph, wind gust: is out of the NNW to 13 mph, humidity 68%, dew point 56°, current freezing level is near 13,500', observation time temperature was 60°, and the barometric pressure 29.91" and falling. |

Mid afternoon weather for 8/14-mostly overcast (scattered Cirrus and Altocumulus-the dominant variety), temperatures are in the upper 80's to low 90's, BP 29.79"F along with calm winds. Yesterday, it was mentioned that a strong system over the Pacific had moved closer to WA though most of its energy was to move NE into BC according to both the GFS and NAM models. It has since moved North over the Pacific just West of the Queen Charlottes. The cloud cover is believed to be a result of "clouds" moving up the NW side of high pressure over the area. In addition, it was also mentioned that both the freezing level and high temperatures would begin a gradual decline from today through Saturday. The culprit responsible for this slight cooling trend is a weak cold front that should move over "the Cascades this afternoon", and "across the Inland NW by tomorrow and Saturday". As a result, there is a chance for light showers {though the UW model is already showing a band of light rain moving SW to NE toward this area}, a "few thunderstorms" and "breezy winds". Current conditions for 8/15-overcast (Cirrus, dense Cirrostratus and scattered Altocumulus), no precipitation in the last 24, the smoke/haze is moderate with little or no air movement. It is first from the West at 2 mph, then the South at 3 mph, wind gust: out of the WNW to 15 mph, humidity 58% (yesterday, the reading was 68%), dew point 58°, current freezing level is near 12,000' [yesterday, it was near 13,500'], observation time temperature was 71°, and the barometric pressure 29.86" and falling. |

Mid afternoon weather for 8/16-partly cloudy (scattered Altocumulus and Cumulus) on a very pleasant summer afternoon. Temperatures are in the upper 80's to low 90's, BP 29.85"F along with light air movement first from the East, then the South and finally the SE. This should be the final day of gradual decline for both the freezing level (dropped from a maximum level of 11,000' yesterday, to 10,500' today) and high temperatures (should reach the mid 80's today compared to the mid to upper 80's yesterday) in part because of a weak, slow moving cold front-mentioned yesterday-that will move across "Eastern WA" today, and a slight dip in the NPJ over NW WA which may allow an onshore flow over Vancouver Island and Southern BC-near the WA border-and a chance for isolated showers in the Northern Cascades as a result of a weak disturbance off the WA coast. Looking ahead, there are indications of another warming trend from tomorrow through early next week with high temperatures like to reach the low to mid 90's by the latter part of the period. Current conditions for 8/17-increasing clouds since earlier this morning (scattered Cirrus, Cirrostratus, Cumulus and a large band of Altostratus-the dominant variety), no precipitation in the last 24, the haze is light to moderate with little or no air movement. It is first from the WNW at 2-5 mph, then the SE at 2 mph, wind gust: out of the NW to 14 mph, humidity 53% {yesterday, the reading was 65%}, dew point 56°, current freezing level is near 10,500', observation time temperature was 64°, and the barometric pressure 29.94" and falling.

Mid afternoon weather for 8/17-from mostly cloudy earlier in the day, to mostly clear. Temperatures are in the mid 80's, BP 29.93"F along with light air movement from the NW. High pressure (off the coast of central OR) over WA-as well as OR, ID and Western MT-will result in warmer temperatures and continued dry conditions through mid week. However, now that we have entered the second half of August, it is believed that these warmer temperatures are not likely to reach 100 degrees {as the "highs" now begin a "very slow descent toward fall"} though the the low to mid 90's are still a good bet for Eastern WA. Current conditions for 8/18-clear skies, no precipitation in the last 24, the haze is light with little or no air movement. It is first from the WNW at 2-4 mph, then the SE at 5 mph, wind gust: out of the NW to 14 mph, humidity 56%, dew point 53°, current freezing level is near 13,500' [yesterday, it was near 10,500'], observation time temperature was 62°, and the barometric pressure 30.01" and rising. |

Mid afternoon weather for 8/18-clear skies (except for scattered Cirrus from the SW to the NE, and Cumulus to the NW), temperatures are in the upper 80's to low 90's, BP 29.90"F along with gentle, light air movement first from the East, then the South, the SW, North, and finally the NE. Although much of Eastern WA should see high temperatures reach the upper 80's to low 90s today through mid week, one model shows an occluded front extending East over Southeastern BC and Southern Alberta. There are however, indications of yet another cooling trend that should commense by sometime Thursday and persist through the weekend. This cooling trend is quite possibly the result of an upper level low-currently off the Northern CA coast-that will migrate inland, track NE toward the NW, weaken in the process and end up over SE OR according to the Canadian model while the GFS model shows it over NE OR. Current conditions for 8/19-mostly clear (scattered Cumulus), no precipitation in the last 24, the haze is light with some nice air movement. It is first from the West at 7 mph, then the NW to 6 mph, wind gust: out of the WNW to 18 mph, humidity 41% (yesterday, the reading was 56%) dew point 50°, current freezing level is near 13,500', observation time temperature was 66° {which is about 11 degrees above average}, and the barometric pressure 29.97" and falling. |

Mid afternoon weather for 8/20-although smoke covers most of the valley, and is especially thick to the North-Burch mountain is completely obscured-the sky is clear above the smoke. Temperatures are in the upper 80's to low 90's, BP 29.90"F along with light air movement from the NW. Even though today should be the warmest day of the week with highs likely to reach the upper 80's to low 90's, a cooling trend-mentioned yesterday-is impending sometime tomorrow and persist through at least the weekend. This cooling trend is believed to be the result of an upper level low-still spinning off the Northern CA coast-which will eventually move inland, then track NE toward the NW and end up over SE WA by sometime "Thursday afternoon through Friday evening". Although this upper level low will be "weak" when it arrives over SE WA (according to the GFS, NAM, and Canadian models), it will be strong enough to generate "showers and thunderstorms" over extreme Eastern WA as well as the Northern and central panhandle of ID while further to the West, it looks as though this area will miss the "action"! Current conditions for 8/21-clear skies (except for scattered Cirrus and contrails from the SW to the SE and smoke), no precipitation in the last 24, the smoke/haze is moderate with little or no air movement. It is first from the West at 3-4 mph, then the South at 4 mph, wind gust: out of the WNW to 16 mph, humidity 60% {yesterday, the reading was 40%}, dew point 49°, current freezing level is near 14,000', observation time temperature was 55°, and the barometric pressure 30.05" and rising.

The amount shown had already been recorded when I got up this morning. Mid afternoon weather for 8/22-overcast (dense Altostratus, scattered Altocumulus) and somewhat ominous to the West. Temperatures are in the mid to upper 80's, BP 29.75"F along with minimal air movement from the SE. Weak low pressure off the NW half of Vancuver Island should bring showers not only to Vancouver Island, but also the Southern half of the Queen Charlottes as well as the central coast of BC while at the same time usher in cooler air over SW BC, the SE half of Vancouver Island and WA. High temperatures for today should reach the low to mid 80's although there is a possibility for "isolated thunderstorms". The main concern with these thunderstorms is "brief heavy rain". However, by early next week-while the central US "bakes"-the PNW will be somewhat cooler than the past few days {as one model shows a cold front tracking East by SE toward Vancouver Island, WA and OR} with a chance for showers over and West of the Cascades. Current conditions for 8/23-mostly cloudy (scattered Cirrus, Cirrostratus, and Cumulus), no precipitation since earlier this morning, the haze/smoke is moderate with little or no air movement. It is first from the West at 3-4 mph, then the North at 2 mph, wind gust: out of the WNW at 13 mph, humidity 63%, dew point 59°, current freezing level is near 10,500', observation time temperature was 66°-which, at the time, was 12 degrees above normal-and the barometric pressure 29.74" and falling. |

Mid afternoon weather for 8/23-mostly cloudy (scattered Cirrus, Cirrostratus, and widely scattered Cumulus), temperatures are in the low to mid 80's, BP 29.70"R along with light air movement from the NW at 3-6 mph. Although the warmth persists SE of WA, not much change has occurred since yesterday, in this area, as an upper level low-spinning just off the Southern central coast of BC-appears to be responsible for "rotating" cooler air over WA as one model shows a cold front now tracking East by SE over WA and NW to SW OR. As a result, high temperatures today should reach the upper 70's to low 80's. However by early next week, it should be wet from the "Cascades to the coast" while Eastern WA is likely to be sunny and warm with highs projected to reach the mid to upper 80's. Current conditions for 8/24-from mostly overcast earlier this morning to mostly clear (widely scattered Cirrus and Cumulus), no precipitation in the last 24, the haze is light to moderate with little or no air movement. It is first from the WNW at 1-3 mph, then the East at 3 mph, wind gust: out of the NW to 14 mph, humidity 47%, dew point 50° {yesterday, the readings were 63% and 59° respectively}, current freezing level is near 10,000', observation time temperature was 63°, and the barometric pressure 29.79" and falling. |

Mid afternoon weather for 8/24-partly cloudy (scattered Cirrus, Cirrocumulus, Cirrostratus-to the NW-a band of Altocumulus from the SW to the NW, and Cumulus), temperatures are in the low to mid 80's, BP 29.71"F along with light air movement first from the East, then the South, and finally the SE. The ridge of high pressure that yesterday was over WA, has since moved slightly East and as a result, will continue to be very warm SE of WA while this area remains "cool" for the time being. Because a SW flow over WA is due to the configuration of the high pressure, this should allow for a "moist flow to set up" over WA along with a chance for "showers and thunderstorms" during the late afternoon/early evening hours today as well as a possibility of "heavy rain" today and tomorrow. Current conditions for 8/25-mostly cloudy (scattered Cirrus, Cirrostratus, and Altocumulus), no precipitation in the last 24, the haze/smoke is light to moderate with little or no air movement. It is first from the WNW at 5 mph, then the East at 4 mph, wind gust: out of the NW to 16 mph, humidity 51%, dew point 50°, current freezing level is near 10,000', observation time temperature was 63°, and the barometric pressure 29.85" and falling. |

The amount shown was recorded yesterday during the later evening hours. Mid afternoon weather for 8/25-an Altostratus overcast (except for partial clearing to the NW) and scattered Cumulus. Temperatures are in the upper 70's to low 80's, BP 29.77"F along with light air movement from the NW. Low pressure spinning West of the Queen Charlottes should be responsible for showers over and West of the Cascades (although there is a threat-once again-for "thunderstorms this afternoon and evening" along with a "possibility of heavy rain") as well as NW OR. In addition, a cold front-associated with this low pressure-is shown tracking East by SE toward Vancouver Island, WA and OR. However by mid week, and because of a persistent SW flow over WA, the "heat wave" continues in the Mid West while in the NW, a second, and somewhat stronger system, should bring showers to Western WA and NW OR. Interestingly, high temperatures in this area should rise from the upper 70's to low 80's today, to the mid to upper 80's by Wednesday. Current conditions for 8/26-partly cloudy (scattered Cirrus, denser Cirrus, Altocumulus and Cumulus), no pecipitation during the overnight, the haze/smoke is light to moderate with little or no air movement. It is first from the East at 3-6 mph, then the SE at 3 mph, wind gust: out of the East at 10 mph, humidity 74%, dew point 57° {yesterday, the readings were 51% and 50° respectively}, current SNOW level is near 9000' [yesterday, it was near 10,000'], observation time temperature was 56°, and the barometric pressure 29.88" and falling. |

Mid afternoon weather for 8/26-mostly overcast (except for partial clearing to the NE and SE) and very ominous from the West to the SW. Temperatures are in the upper 70's to low 80's, BP 29.84"F along with a gentle breeze mainly from the SE at 5-12 mph. Although it will continue to be very warm SE of WA as a result of a persistent SW flow, one model shows the first in a series of systems that should bring moist air and showers mainly to central and SW BC as well as Vancouver Island while only "clipping" NW WA (both the Olympic Peninsula and Whatcom county). Even by the end of the work week, little change is expected as yet another system is projected to bring showers over and West of the Cascdes in WA and NW OR. By way of contrast however, Eastern WA should experience dry conditions and warmer temperatures with highs likely to reach the low to mid 80's today, and the mid to upper 80's tomorrow. Current conditions for 8/27-partly cloudy (scattered Cirrus, Cirrostratus, and Cumulus), no precipitation during the overnight, the haze is light to moderate with little or no air movement. It is first from the North at 1-2 mph, then the SE at 3 mph, wind gust: out of the NNE to 13 mph, humidity 66%, dew point 55°, current freezing level is near 10,000' [yesterday. it was near 9000'], observation time temperature was 56°, and the barometric pressure 29.92" and rising.

Mid afternoon weather for 8/27-mostly cloudy (scattered Cirrus, Cirrostratus, Altocumulus, Cumulus, and a large Cumulus Congestus cloud to the NE), temperatures are in the low to mid 80's, BP 29.77"R along with slight air movement from the North. In a similar pattern to yesterday, it appears that the second-in a series of systems-will bring moist air and showers mainly to SW BC, Vancouver Island, and WA (over and West of the Cascades) while Eastern WA should continue to bask in dry conditions and pleasant temperatures with highs likely to reach the low to mid 80's. There are indications that even though late summer is upon us (only 25 days until the onset of autumn!), and because high pressure will be firmly established over WA, it looks as though continued dry conditions and warmer temperatures are in store for the first part of the week end in Eastern WA with highs reaching the mid to upper 80's, and a possibility of nudging the low 90's by Saturday. Current conditions for 8/28-partly cloudy (scattered Cirrus, Cirrostratus, Altocumulus and Cumulus), no precipitation in the last 24, the haze is light with some air movement. It is first from the West at 4-6 mph, then the North at 3 mph, wind gust: out of the WNW to 18 mph, humidity 65%, dew point 59°, current freezing level is near 10,500', observation time temperature was 60°, and the barometric pressure 29.79" and rising. |

The amount shown was recorded last evening at the time listed below. Mid afternoon weather for 8/28-mostly cloudy (scattered Cirrus, Cirrostratus as well as Cumulus) and somewhat ominous to the West. Temperatures are in the low to mid 80's, BP 29.78"F along with a light to gentle breeze from the NW at 3-8 mph. Low pressure spinning off the SW half of Vancouver Island, should bring rain to Vancouver Island, SW BC and most of the coastal area of WA, but only isolated showers over and West of the Cascades. As for Eastern WA, much the same as yesterday, with dry conditions (although there is a threat for isolated showers and thunderstorms this afternoon which would "bring the potential for lightening, heavy rain, and gusty outflow winds") and pleasant temperatures. Highs for today should, once again, reach the low to mid 80's. Looking ahead to the weekend, it must be remembered that since we are in the latter part of summer, and that the first half of the weekend will feature warmer temperatures in Eastern WA with highs likely to reach the mid to upper 80's, and a possibility of nudging the low 90's by Saturday as a result of high pressure firmly established over WA, the very warm temperatures (mid to upper 90's, and low 100's) will probably not be realized until next summer. Current conditions for 8/29-mostly cloudy (scattered Cirrus, Altocumulus and Cumulus), no precipitation in the last 24, the haze is light with some air movement. It is first from the West at 3-5 mph, then the South at 3 mph, wind gust: out of the WNW to 15 mph, humidity 70%, dew point 60°, current freezing level is near 10,500', observation time temperature was 62°, and the barometric pressure 29.87" and falling. |

Although high temperatures today will be several degrees above normal in Eastern WA, it appears as though changes are forthcoming by mid week. Mid afternoon weather for 8/31-clear skies, temperatures are in the mid to upper 80's on a very pleasant afternoon, BP 29.86"F along with light air movement first from the East, then the South, and finally the SE, not to mention a spectacular view of Glacier Peak to the NW. Current conditions for 9/01-clear skies, no precipitation in the last 24, the haze is light with little or no air movement. It is first from the North at 14 mph, then the SE at 3 mph, wind gust: out of the North to 14 mph, humidity 57% (yesterday, the reading was 89%), dew point 53°, current freezing level is near 13,500', observation time temperature was 56°, and the barometric pressure 29.88" and falling. Here are some interesting stats for AUGUST- 1) total rain: 0.77", or about 188% of average. It also turned the total rain deficit of 0.34" in July to a 0.02" surplus for August, 2) number of days with no precipitation: 21, 3) high BP: 30.07" on 8/31, 4) low BP: 29.74" on 8/23, 5) date with low BP and no precipitation: 29.79" on 8/24, 6) date with high BP and precipitation: 29.98" on 8/11 (T), 7) average BP: 29.93", 8) average morning temperature- a) official minimum: 61.6°, b) normal low: 55.9°, c) digital: 62.9°, 9) low morning temperature- a) official minimum: 54° on 8/31, b) digital: 55.2° on 8/31, 10) high morning temperature- a) official maximum: 71° on 8/15, b) digital: 72.1° on 8/15, 11) average afternoon temperature- a) official maximum: 88.6°, b) normal high: 86.6°, c) digital: 85.4°, 12) low afternoon temperature- a) official minimum: 81° on 8/02, & 8/29, b) digital: 77.4° on 8/02, and 13) high afternoon temperature- a) official maximum: 99° on 8/07, b) digital: 96.3° on 8/09. |

Mid afternoon weather for 9/01-clear skies on a gorgeous late summer afternoon, temperatures are in the low to mid 90's, BP 29.72"F along with light air movement first from the SE, then the East, and finally the South. Even though high pressure is established over central Alberta and Saskatchewan, ID, MT, WY, SE BC as well as Eastern WA and OR, its axis is over Western MT. As such, dry conditions and warm temperatures should prevail another day in Eastern WA with highs likely to reach the mid 80's though showers and thunderstorms are a threat through out the week. "Some of these thunderstorms may become strong with heavy downpours, gusty winds, hail, and dsngerous lightening". However, a cut-off upper level low still spins off the SW coast of WA (as shown by the UW model) and should continue to do so until mid week, when, at that point, track NE {and be right over WA Friday and Saturday according to the GFS model} toward the Northern panhandle of ID. Current conditions for 9/02-mostly clear (Cirrostratus from the South to the SE, Cumulus Congestus near the Eastern horizon, and widely scattered Cirrus and Cumulus), no precipitation in the last 24, the haze is light to moderate with little or no air movement. It is first from the NNE at 6 mph, then the North at 6 mph, wind puff: out of the NE at 7 mph, humidity 47% (yesterday, the reading was 57%), dew point 56°, current freezing level is near 11,000' [yesterday, it was near 13,500'], observation time temperature was 62°, and the barometric pressure 29.78" and falling.

Mid afternoon weather for 9/02-mostly clear (scattered Cirrus, Cirrostratus, and Cumulus), temperatures are in the upper 80's to low 90's, BP 29.73"F along wih slight air movement from the SE. As was mentioned yesterday, the closed and slow moving upper level low continues to spin off the WA/OR coast and should persist until at least mid week at which time it should finally commence to track NE (and by the end of the work week into Saturday, looks to be right over WA according to the GFS, NAM and Canadian models) toward the Northern panhandle of ID. At the present time however, this upper level low is close enough to bring "weather" from the South over and West of the Cascades according to the models just mentioned. In the meantime, the highs today in Eastern WA should reach the low to mid 80's although showers and thunderstorms are a threat throughout the week. Some of these thunderstorms should become strong with a good chance of heavy rain tomorrow, but "more significant rain is expected Wednesday into Thursday". Current conditions for 9/03-mostly clear (scattered Altocumulus and Cumulus), no precipitation in the last 24, the haze is light to moderate with little or no air movement. It is first from the North at 6 mph, then the South at 2 mph, wind puff: out of the NNE at 8 mph, humidity 72% (yesterday, the reading was 47%), dew point 60°, current freezing level is near 10,500', observation time temperature was 64°, and the barometric pressure 29.87" and falling. |

The amount shown was recorded at some point during the overnight. Mid afternoon weather for 9/03-partly to mostly cloudy (scattered Cirrus, Cirrostratus, denser Cirrostratus, Cumulus, and ragged Cumulus), temperatures are in the upper 80's to low 90's, BP 29.82"F along with a light to gentle breeze mainly from the NW at 3-8 mph. As has been the case for the past few days, this persistent closed upper level low continues to spin off the NW OR coast and should bring showers to Vancouver Island, the coastal areas of WA and NW OR. However, this upper level low will slowly approach the "coast" by tomorrow and Friday thereby setting up an unstable air mass over WA. What does this mean for Eastern WA? Although showers and thunderstoms have been a threat so far this week, it looks as though these thunderstorms will finally become a reality tomorrow into Friday. Some may be "strong or severe", "produce large hail and damaging wind gusts". Then, believe it or not, there is the possibility for "localized funnel clouds or weak short lived tornadoes"!. In addition, significant rain is very probable and some "locations could receive as much as 1-2 INCHES of rain". Current conditions for 9/04-clear skies (except for some widely scattered Cumulus), the haze is light to moderate with little or no air movement. It is first from the North at 9 mph, then the South at 3 mph, wind gust: out of the WNW to 11 mph, humidity 65%, dew point 58°, current freezing level is near 11,500' [yesterday, it was near 10,500'], observation time temperature was 63°, and the barometric pressure was 29.94" and rising.

Mid afternoon weather for 9/04-partly cloudy (a few bands of Altocumulus from the SW to the NW, scattered Cumulus-dominant variety-Cumulus Congestus to the North and NW, and ragged Cumulus), temperatures are in the low to mid 90's, BP 29.84"R along with light air movement first from the East, then the South and finally the SE. The big story is the persistent, slow moving and "closed" upper level low that has continued to spin off the NW OR coast for the past several days. As of today, it will finally move closer to the coast "later tonight" then be directly over WA tomorrow and Saturday (according to both the GFS and NAM models) thereby setting up an unstable air mass over WA. Even though thunderstorms have been a threat through out the week, today they should be a reality over and West of the Cascades (where one model-UW-shows two bands of moderate to heavy rain embedded within them, tracking SE to NW West of Olympia, Eastern Olympic Peninsula, and the San Juans) while severe thunderstorms are likely in Eastern WA and the entire panhandle of ID. These thunderstorms could produce "large hail, damaging wind gusts", and, as was mentioned yesterday, there is the possibility for "localized funnel clouds" or weak short lived tornadoes". In addition, significant rain is very probable and some locations could receive as much as 1-2 INCHES of rain. Current conditions for 9/05-mostly cloudy (scattered Cirrus, Cirrostratus and Altocumulus), no precipitation in the last 24, the haze is moderate with little or no air movement. It is first from the North ata 8 mph, then the NW at 2 mph, wind gust: out of the North to 11 mph, humidity 66%, dew point 59°, current freezing level is near 11,000', observation time temperature was 68°, and the barometric pressure 29.93" and rising. |

The amount shown was recorded last evening during the hours given below. Mid afternoon weather for 9/05-overcast (except for some partial clearing from the North to the NE) and somewhat ominous. Temperatures are in the mid to upper 80's, BP 29.79"R along with calm winds. Although this area did not realize large hail, damaging wind gusts, localized funnel clouds or weak short lived tornadoes, we did witness a splendid display of heat and fork lightening as well as a generous amount of rain. In the meantime, this persistent, slow moving, and closed upper level low is not quite finished with us yet as it should now be directly over WA today and is expected to remain through Sunday though weaken in the process according to the GFS, NAM, and Canadian models. Hence, there is the likelihood of additional showers and thunderstorms today. Following the passage of this upper level low, there are indications of a warming trend that should commence by sometime Saturday, and is projected to persist through most of the work week resulting in drier conditions and warmer temperatures. Current conditions for 9/06-overcast with showers-heavy at times-and little or no air movement. It is first from the NNE at 3 mph, then the S at 2 mph, wind puff: out of the NE to 6 mph, humidity 87% (yesterday, the reading was 66%), dew point 61°, current snow level is near 9500' [yesterday, it was near 11,000'], observation time temperature was 60°, and the barometric pressure 29.94" and rising. |

The amount shown was recorded yesterday during the hours listed below. Mid afternoon weather for 9/06-from overcast and rainy skies earlier in the day, to partly cloudy (scattered Cirrus and Cumulus Congestus), temperatures are in the upper 60's to low 70's, BP 30.02"R along with minimal air movement from the SW. Although this persistent slow moving, closed upper level low (it has been newsworthy for the past four days!) is now over NE WA-near the Canadian border-it should remain over WA through sometime tomorrow according to the GFS, NAM, and Canadian models. Hence, the likelihood of more showers and thundershowers-along with a "continued threat for heavy rain"-in Eastern WA today before this upper level low slowly moves East of WA. Following the passage of this upper level low, there are indications of a return to summer like weather as another ridge of strong high pressure will dominate most-if not all-of the work week. Highs during this period should reach the upper 80's to low 90's and possibly the mid 90's on the warmest days {Tuesday and Wednesday}. Current conditions for 9/07-overcast (low clouds and patchy fog obscuring most of the higher ridges and peaks around the valley), no precipitation during the overnight, the haze is moderate with little or no air movement. It is first from the East at 4 mph, then the North at 2 mph, wind puff: out of the SSE to 7 mph, humidity 85%, dew point 59°, current freezing level is near 11,000' [yesterday, it was near 9500'], observation time temperature was 60°, and the barometric pressure 30.08" and rising. |

The amount shown occurred sometime yesterday. Mid afternoon weather for 9/07-from overcast (low clouds and patchy fog) and intermittent showers earlier in the day, to partly cloudy skies (scattered Altocumulus, Cumulus, and patchy fog), temperatures are in the upper 60's to low 70's, BP 30.02"R along with calm winds. This persistent, slow moving upper level low has finally moved East of WA over NW MT-near the border of SE BC-and in its place, another ridge of strong high pressure-currently off the OR coast-will build in behind it and be firmly established through much of the upcoming work week thus bringing a return to summer like weather in Eastern WA. Highs during the period should reach the mid to upper 80's with the possibility of nudging the low 90's, and maybe even the mid 90's on the warmest days {Tuesday and Wednesday}. Current conditions for 9/08-clear skies, no precipitation during the overnight, the haze is moderate to bad with little or no air movement. It is first from the East at 0 mph, then the SE at 3 mph, wind puff: out of the ENE to 4 mph, humidity 75% {yesterday, the reading was 85%}, dew point 57°, current freezing level is near 13,500' [yesterday, it was near 11,000], observation time temperature was 53°, and the barometric pressure 30.07" and rising. |

Mid afternoon weather for 9/08-mostly clear (except for widely scattered Cirerus and Cumulus), and very pleasant for a late summer afternoon. Temperatures are in the low to mid 80's, BP 29.79"R along with light air movement first from the East, then the South, and finally the SE. Strong high pressure is firmly established over WA (and has forced the storm track well to the north of WA over North western BC) and it is projected to remain over the area through much of the work week. However, because we are in the latter days of summer (only 12 days left!), normal high temperatures for the week-in Eastern WA-should be in the low 80's; but, due to the strength of this high pressure, the highs are likely to reach the mid to upper 80's and possibly the low 90's through much of the week and maybe even the mid 90's on the warmest days {tomorrow and Wednesday}. It is believed therefore, that the record high temperatures for this week will likely be challanged. Current conditions for 9/09-clear skies, no precipitation in the last 24, the haze is light to moderate with little or no air movement. It is first from the North at 3 mph, then the South at 2 mph, wind puff: out of the NNW at 8 mph, humidity 62% [yesterday, the reading was 75%], dew point 55°, current freezing level is near 14,000', observation time temperature was 58°, and the barometric pressure 29.95" and falling.

Mid afternoon weather for 9/09-clear skies (except for scattered Cumulus from the West to the South, on a warm, late summer afternoon. Temperatures are in the upper 80's to low 90's (which is about 7-10 degrees above normal), along with gentle air movement first from the East, then the South, and finally the SE at 3-7 mph. Strong high pressure-off the WA coast-now firmly established over WA, has forced the storm track well north of WA over the Alexander Archipelgo, NW BC and Southern Yukon-near the BC border. In addition, it not only is projected to remain over the area through most of the work week, but looks to strengthen somewhat by tomorrow and Thursday {according to both the ECMWF and Canadian models}. As was mentioned yesterday, we are in the latter days of summer-only 11 days left!-and the normal highs for the week in Eastern WA should be in the low 80's; but, because of its (the ridge of high pressure) strength, the highs are likely to reach the mid to upper 80's for much of the work week, and possibly even the low to mid 90's by tomorrow and Thursday. If these maximum high temperatures are realized, it is believed that the record high temperatures for this week in September will be seriously challenged. Current conditions for 9/10-clear skies, no precipitation in the last 24, the haze is light to moderate with little or no air movement. It is first from the North at 6 mph, then the SE at 5 mph, wind puff: out of the NNW to 8 mph, humidity 65%, dew point 56°, current freezing level is near 16,000' [yesterday, it was near 14,000], observation time temperature was 60°, and the barometric pressure 29.99" and rising. |

Mid afternoon weather for 9/10-clear skies, temperatures are in the upper 80's to low 90's (which is about 8-10 degrees above the normal highs for this day in September), BP 29.89"F along with minimal air movement from the SW. Strong high pressure both at the surface ( yesterday it was off the WA coast and since then has moved directly over central WA according to the Canadian model) an aloft is now firmly established over WA (and since yesterday, has forced the storm track even further north over most of Eastern AK and the Yukon as well as the far West portion of the NW Territories) appears to have strengthened somewhat since yesterday. As a result, today and tomorrow should be the warmest days of the week with highs likely to reach the low to mid 90's. If these high temperatures are realized, it is believed that the record high temperatues for this week in September will be seriously challanged. However, after tomorrow, there are indications of a gradual cooling trend through the first part of the weekend, then from this period through early next week, it is projected to cool even further and hence, approach more "fall like" weather. Current conditions for 9/11-clear skies, no precipitation in the last 24, the haze is light to moderate with little or no air movement. It is first from the WNW at 5 mph, then the SE at 2 mph, wind gust: out of the NW to 12 mph, humidity 57%, dew point 56°, current freezing level is near 16,000', observation time temperature was 56°, and the barometric pressure 30.03" and rising. |

Mid afternoon weather for 9/11-clear skies, temperatures are in the upper 80's to low 90's (though these temperatures are 8-10 degrees above normal for this day in September, the record high of 96° missed tying the record by only five degrees on this date back in 1990!), BP 29.92"R along with light air movement first from the East, then the South and finally the SE. Strong high pressure both at the surface {which yesterday was directly over central WA has since shifted East over north central MT} and aloft, will continue to be firmly established over WA through the end of the work week. As a result, the high temperaures during this period should, once again, reach the upper 80's to low 90's which is still 8-10 degrees above normal. There continues to be indications of a gradual cooling trend to commence by the first part of the weekend, then from this point through early next week, it is projected to cool even further and hence approach seasonal or "fall like" weather as a result of a pattern change due to a big, strong low pressure system that should bring moisture over and West of the Cascades. Current conditions for 9/12-clear skies, no precipitation in the last 24, the haze is moderate to bad with little or no air movement. It is first from the WNW at 4-5 mph, then the South at 2 mph, wind gust: out of the NW to 14 mph, humidity 77% (yesterday, the reading was 57%), dew point 56°, current freezing level is near 15,500', observation time temperature was 58°, and the barometric pressure 30.00" and falling. |

Mid afternoon weather for 9/12-scattered Cirrus and Cirrostratus in the southern half of the sky while from that point north, the skies were clear. Temperatures are in the upper 80's to low 90's (which is still 8-10 degrees above the normal high of 80°), BP 29.80"F along with minimal air movement from the SW. For the past several days, strong high pressure over WA has resulted in above normal temperatures and challenged record highs for this week in September and today is no exception. Consequently, the highs for Eastern WA are likely, once again, to reach the upper 80's to low 90's (which is still about 10-13 degrees above normal). In the meantime, a gradual cooling trend-mentioned yesterday-should commence tomorrow, then from that point through mid week is projected to cool even further and hence, approach seasonal or "fall like" weather. However, it appears that tomorrow will be the last day of very summer like weather for Western WA as a disturbance coming up from the SW should bring the possibility of showers or thunderstorms. Current conditons for 9/13-clear skies, no precipitation in the last 24, the haze is moderate to bad with little or no air movement. It is first from the West at 4-6 mph, then the SE at 2 mph, wind gust: out of the WNW to 10 mph, humidity 56% {yesterday, the reading was 77%}, dew point 58°, current freezing level is near 15,000', observation time temperature was 59°, and the barometric pressure 29.83" and falling. |

Mid afternoon weather for 9/13-clear skies (except for some widely scattered Cumulus from the West to the East) on a very warm, late summer afternoon. The high today {95°} came within one degree of tying the record high on this date way back in 1960! BP 29.67"F along with light air movement first from the East, then the South, the SE, though occasionally from the NE and SW. While hot weather should continue for one more day in Eastern WA {due to high pressure over WA-which appears to have strengthened somewhat since yesterday}, today looks to be the last day of very summer like weather for Western WA as a "vigorous low pressure system/disturbance" from the SW brings the likelihood of showers and scattered thunderstorms to the area just mentioned. Some changes for Eastern WA appear to be on the way as thunderstorms are possible during late tomorrow afternoon, "evening and overnight hours". Some of these storms may be "strong to locally severe and produce hail, gusty winds, and heavy rainfall". In the meantime, the gradual cooling trend-which has been mentioned for the past few days-will finally commence in ernest by sometime this evening, then from that point through early next week cool even further thus heralding the onset of more seasonal or "fall like" weather. Current conditions for 9/14-mostly clear (scattered Cirrus and Cirrostratus), no precipitation in the last 24, the haze is moderate to bad with little or no air movement. It is first from the North at 0-5 mph, then the NE at 2 mph, wind gust: out of the NW to 16 mph, humidity 54%, dew point 59°, current freezing level is near 15,000', observation time temperature was 61°, and the barometric pressure 29.80" and rising. |

Mid afternoon weather for 9/14-mostly overcast (scattered Cirrus, Cirrostratus and Altostratus), temperatures are in the upper 80's to low 90's-or about 9-11 degrees above normal-BP 29.71"R along with calm winds. Even though high pressure is still over WA, the cooling trend is underway and is now projected to persist through much of next week thus heralding the onset of more seasonal or "fall like" weather and quite possibly the end of the very warm summer like temperatures experienced last week. In the meantime, because of a strong cold front tracking through the area this evening and encountering a " moist air mass", showers and scattered thunderstorms are likely to move over the area during the late afternoon, evening, and overnight hours. Some of these storms could be strong and thus, bring the potential for heavy rainfall, "small to moderate hail, damaging winds and abundant lightening strikes". Current conditions for 9/15-from mostly cloudy earlier this morning, to partly cloudy (scattered Altocumulus), no precipitation in the last 24, the haze is moderate to bad with little or no air movement.It is first from the West at 6 mph, then the SE at 1 mph, wind gust: out of the WNW to 11 mph, humidity 61%, dew point 60°, current freezing level is near 12,000' [yesterday, it was near 15,000'], observation time temperature was 64°, and the barometric pressure 29.79" and rising. |

The amount shown was recorded last evening during the second half of the Seahawk game. Mid aftenoon weather for 9/15-mostly cloudy (scattered Cirrus, Cirrostratus, Cumulus, ragged Cumulus and Cumulus Congestus-toward the North), and somewhat ominous to the West and SW. Temperatures are in the upper 80's to low 90's-which is still about 10 degrees above normal-BP 29.58"F along with light air movement from the NW at 3-6 mph. Even though last evening was a similar repeat of the 9/06 storm, this area, anyway, did not realize small to moderate hail, damaging winds, or heavy rain, (in other words, the main energy of this strong storm just brushed the area) we did experience a spectacular display of both heat and fork lightening. This strong storm-which mainly affected central and NE WA-was the result of a strong cold front tracking through the "area" last evening but in the process encountered a "moist air mass" and hence, caused the air to become very unstable. Since last evening however, the cold front has moved East of WA, and the strong storm that brought this area a spectacular display of lightening continues to move NW over most of BC and the SE portion of the Yukon as a result of low pressure just West of the Alexander Archepelago. Looking ahead to the end of the work week, there are indications of more wet weather as the next system should bring showers and thunderstorms to the lower elevations of Western WA and the possibility of a rain/snow mix above pass levels through the weekend while Eastern WA is likely to remain dry. Current conditions for 9/16-partly cloudy (scattered Cumulus and Cumulus Congestus-toward the North), the haze is light along with some air movement. It is first from the North at 4-5 mph, then the NW at 5 mph, wind gust: out of the North to 13 mph, humidity 55%, dew point 54°, current snow level is near 9000' [yesterday, it was near 12,000'], observation time temperature was 59°, and the barometric pressure was 29.77" and rising. |

Mid afternoon weather for 9/16-partly cloudy (scattered Cirrus, denser Cirrus, and Cumulus), temperatures are in the mid to upper 70's, BP 29.77"R along with a gentle breeze from the NE at 3-8 mph. Although one model shows a trough digging into Northern CA and low pressure over the central coast of OR, the cooling trend in Eastern WA is well underway and its effect should be noticed today as the highs should only reach the mid to upper 70's. Quite a contrast to last week when the highs were well above normal! This "trend" will be interrupted by a brief warming trend as high pressure builds in over WA tomorrow, Thursday and possibly Friday (according to the ECMWF model) before the next system arrives by the end of the work week with showers and possibly some "unsettled" weather for the lower elevations of Western WA while above pass levels, a chance for a rain/snow mix lingers through the weekend as the minimum snow level hovers between 7000'-7500' during the period. Current conditions for 9/17-mostly cloudy (scattered Cirrus, Cirrostratus, Altocumulus, Altocumulus perlucidus, and Cumulus), no precipitation in the last 24, the haze is light to moderate with some air movement. It is first from the North at 1-4 mph, then the SW at 1 mph, wind gust: out of the NNW to 11 mph, humidity 75% {yesterday, the reading was 55%}, current snow level is near 8000' [yesterday, it was near 9000'], observation time temperature was 54°, and the barometric pressure 29.78" and rising. |

Mid afternoon weather for 9/17-overcast (Altostratus, and scattered lower level Cumulus), temperatures are in the low 70's, BP 29.67"F along with a gentle to moderate breeze from the NW at 5-10 mph. Although today should be the coolest day of the week with highs likely to reach only the upper 60's to low 70's, the cooler air will be temporarily put on hold (as high pressure begins to build in over WA today, then strengthen tomorrow and Friday according to the GFS, NAM, Canadian and ECMWF models) but returns with the next storm as "they" arrive by the end of the work week with showers and maybe some "unsettled" weather for the lower elevations of Western WA, while above pass levels, there is a chance for a rain/snow mix by and through the weekend as the minimum snow level hovers between 6500'-7500' during this period. However, with all this upcoming weather, it appears that this area should remain dry for the time being. Current conditions for 9/18-mostly clear (widely scattered Cumulus), no precipitation in the last 24, the haze is light along with some air movement. It is first from the West at 5 mph, then the NW at 5 mph, wind gust: out of the WSW to 16 mph, humidity 44%, dew point 43° {yesterday, the readings were 75% and 52° respectively}, current snow level is near 6000' [yesterday, it was near 8000'], observation time temperature was 50°, and the barometric pressure 29.90" and rising. |

In contrast to yesterday being the coolest day of the week, today should be the warmest day with highs likely to reach the mid to upper 70's as high pressure has indeed strengthened since yesterday and should remain over WA through tomorrow. However, these pleasant conditions will be short lived as changes are on the way. Cooler air-which was evident earlier in the week-will return (and at this point in time, is projected to persist through most of next week) with the next storm-currently West of BC's central coast-by sometime tomorrow bringing showers and maybe some "unsettled" weather to the lower elevations of Western WA while above pass level, the chance for a rain/snow mix by and through the weekend continues as the mimimum snow level hovers between 6500'-7500' during this period. Current conditions for 9/19-mostly clear (widely scattered Cirrus along with several contrails), no precipitation in the last 24, the haze is light to moderate with little or no air movement. It is first from the North at 3-6 mph, then the SE at 1 mph, wind gust: out of the North to 13 mph, humidity 62% {yesterday, the reading was 44%}, dew point 42°, current freezing level is near 12,000' [yesterday, it was near 6000'], observation time temperature was 43°, and the barometric pressure 30.09" and rising. |

Although scattered high clouds have "invaded" the area since earlier this morning, high pressure over WA should persist through today and most of tomorrow before moving East of the state. In the meantime, these pleasent conditions will be short lived as changes are on the way. Cooler air which was evident earlier in the week, will return (and at this point, is projected to persist through much of next week) with the next storm by sometime tomorrow, bringing showers and maybe some "unsettled" weather to the lower evelvations of Western WA. This should be followed by a "stronger, quick moving storm on
Sunday" which packs "gusty winds, locally heavy rain and falling snow levels" as a result of a "passing" cold front. Above pass levels however, there is a good chance for heavy SNOW above 7000' as the minimum snow level should hover between 6500'-7500' during the period. Current conditions for 9/20-mostly cloudy (scattered Cirrus, Cirrostratus and one of the biggest halo's this observer has ever seen!), no pecipitation in the last 24, the haze is light to moderate with little or no air movement. It is first from the North at 3-6 mph, then the East at 2 mph, wind gust: out of the NNW to 12 mph, humidity 54%, dew point 43°, current freezing level is near 10,500' [yesterday, it was near 12,000'], observation time temperature was 43°, and the barometric pressure 29.83" and falling. |

Mid afternoon weather for 9/20-partly cloudy (scattered Cirrus, Cirrocumulus, Cirrostratus, and Altocumulus), temperatures are in the mid 70's, BP 29.54"F along with minimal air movement from the SW. High pressure that was over WA yesterday, has since moved East over MT, and cooler air which was evident earlier in the week has indeed returned and is projected to persist through mid week at which time, it-the air-should turn even cooler (with the "coolest" day likely to be on Tuesday) as the minimum snow level hovers between 5500'-6500' before turning slightly warmer for the remainder of the work week. Meanwhile, the first in a series of storms should arrive today bringing showers and maybe some "unsettled" weather to the lower elevations of Western WA. This will be followed by a second and much stronger, quick moving, storm on Sunday which packs gusty winds, locally heavy rain and falling snow levels as a result of a "passing" cold front. Above pass levels however, there is a good chance of heavy snow above 7000' as the minimum snow level hovers between 5500-6500' (mentioned above). Current conditions for 9/20-partly cloudy (scattered Cirrus, Cirrostratus, Cumulus-the dominant variety) and cool. No precipitation in the last 24, the haze is light with little or no air movement. It is first from the WNW at 5-10 mph, then the North at 5 mph, wind gust: out of the NW to 17 mph, humidity 44%, dew point 48° {yesterday, the readings were 54% and 43° respectively}, current snow level is near 7000' [yesterday, it was near 10,500'], observation time temperature was 58°, and the barometric pressure 29.59" and falling. |

Mid afternoon weather for 9/21-partly cloudy (scattered Cirrus and Cumulus, with virga observed toward the SE), temperatures are in the low to mid 70's, BP 29.57"F along with light air movement from the NW at 5-8 mph. Cool air over this area, is now projected to persist and at the same time become even cooler through mid week as the minimum snow level hovers between 5000'-5500' during this period before turning slightly warmer for the remainder of the work week. In the meantime, the first day of autumn will feature a second storm {which is stronger than its predecessor, vigorous and quick moving} that will arrive over Western WA/OR today packing gusty winds, locally heavy rain (where one model-UW-is showing a very large band of precipitation-with large pockets of moderate rainfall embedded within it- tracking East by NE over NW OR, the coastal areas of WA (including the Olympic Peninsula and the SE portion of Vancouver Island). Due to cooler air behind a passing, potent cold front, the heavy rain should "turn to showers this afternoon" and the snow levels will continue to fall (mentioned above). Current conditions for 9/22-mostly cloudy (scattered Cirrostratus, Altocumulus and Cumulus), no precipitation in the last 24, the haze is light to moderate with little or no air movement. It is first from the West at 5-6 mph, then the South at 3 mph, wind gust: out of the West to 11 mph, humidity 76% (yesterday, the reading was 44%), dew point 46°, current snow level is near 6500', observtion time temperature was 49°, and the barometric pressure 29.64" and falling. |

The amount shown was recorded during the time indicated below. Mid afternoon weather for 9/22-overcast (except for some partial cleaing toward the North and East), temperatures are in the upper 60's to low 70's, BP 29.61"F along with light air movement from the NW. In contrast to yesterday's strong, vigorous, and quick moving storm that brought gusty winds, locally heavy rain and falling snow levels, a large, slow moving, deep upper level trough has begun to move over WA with showers over and West of the Cascades {currently showing on the UW model}, cooler daytime highs statewide and the likelihood of snow in the higher elevations through mid week as the minimum snow level will hover between 5000'-5500' during this period. However, when this upper level trough departs the area (WA) around mid week, "the showers and clouds will slowly decrease" and as a result, the weather should turn slightly warmer for the remainder of the work week. Current conditions for 9/23-mostly overcast (Cirrus, Cirrostratus and Cumulus), no precipitation during the ovenight, the haze is light along with some air movement. It is first from the North at 0-4 mph, then the South at 2 mph, wind puff: out of the NNW to 9 mph, humidity 86% {yesterday, the reading was 76%}, dew point 48°, current snow level is near 6000', observation time temperature was 44°, and the barometric pressure 29.81" and rising. |

Mid afternoon weather for 9/23-mostly overcast (scattered Cirrus, Altocumulus and Cumulus) and ominous to the South and SW, but even more so toward the East. In addition, precipitation was observed falling on or near Mission Ridge to the SW in the form of rain or possibly a rain/snow mix. Temperatures are in the upper 60's to low 70's, BP 29.86"R along with light air movement from the South and West, but a sustained "strong" breeze from the SW. With the southern boundary of a very large, slow moving, and deep upper level trough digging into Northern CA, the door is open for showers West of the Cascades, cooler daytime highs statewide, the likelihood of some snow above pass level through mid week as the snow level hovers between 5000'-5500', and periodic breezy to windy conditons. Although one "forecast" is calling for continued cold conditions for WA, and rain for Western WA during the latter part of the work week, this observer respectfully disagrees with the prediction because indications show that as this upper level trough moves slowy East and finally departs WA by mid week, the "showers and clouds will slowly decrease" and the weather should rebound nicely with warmer daytime highs for the remainder of the work week and into weekend as high pressure begins to build in over WA according to the GFS model. Current conditions for 9/24-mostly cloudy (scattered Cirrus, Cirrostratus, Altostratus and widely scattered Cumulus) and cool. No precipitation in the last 24, the haze is light with some air movement. It is from the West at 4-6 mph, wind gust: out of the WNW to 13 mph, humidity 46%, dew point 37° {yesterday, the readings were 86% and 48° respectively}, current snow level is near 5000' [yesterday, it was near 6000'], observation time temperature was 51°, and the barometric pressure 29.86" and rising. |

Mid afternoon weather for 9/25-mostly cloudy (scattered Cirrus, Cirrostratus, Cumulus, and widely scattered Altocumulus), temperatures are in the mid to upper 60's, BP 29.74"R along with light air movement from the NW. Today should be the coolest day of the week because the very large, slow moving, deep upper level trough (along with low pressure spinning off the SW coast of WA) with its SW boundary now south of the Bay area-in CA-should feature cooler daytime highs statewide, the likelihood of snow above pass levels today, as the snow level hovers near 5000', and periodic breezy to windy conditions. In addition, the overnight lows could be the coolest of the week as a "cold upper level low migrates across the region". Meanwhile, at the same time this upper level trough slowly moves East and finally exits WA by sometime Friday, the weather should rebound- albeit briefly-with slightly warmer temperatures as weak high pressure builds in over WA according to the GFS, NAM, and Canadian models. Current conditions for 9/25-partly cloudy (widely scattered Cirrus, Cirrostratus and Cumulus), no precipitation in the last 24, the haze is light with little or no air movement. It is first from the North at 4-6 mph, then the SE at 3 mph, wind gust: out of the NNW to 12 mph, humidity 61% {yesterday, the reading was 46%}, dew point 42°, current snow level is near 5000', observation time temperature was 47°, and the barometric pressure 29.82" and rising. |

Mid afternoon weather for 9/26-mostly clear (scattered Altocumulus and Cumulus), temperatures are in the mid to upper 60's, BP 29.99"R along with minimal air movement from the South. Even though the upper level trough, of the past several days has finally moved east of WA, and there is weak high pressure over WA, the UW model is currently showing moderate showers tracking East by SE over SW WA, NW OR, and the Tri-Cities area. In the meantime, however, the first of two potent storms will impact the region over and West of the Cascades tomorrow with heavy rain and windy conditions. A second storm will quickly follow the first on Sunday, with more heavy rain and "possibly stronger wind speeds". Believe it or not, the total rainfall amounts from these two storms are "predicted to be 4-8 INCHES for the mountains, and 1.5-3 inches for the lowlands". Interestingly, with the very active weather over and West of the Cascades this weekend,
it appears that this area will be on the fringes of all that abundant energy. Current conditions for 9/27-overcast, the haze is light to moderate with minimal or no air movement. It is first from the WNW at 3 mph, then the West at 2 mph, wind gust: out of the NW to 13 mph, humidity 81%, dew point 44°, current snow level is near 7500' [yesterday, it was near 6500'], observation time temperature was 47°, and the barometric pressure 29.99" and rising. |

The amount shown was recorded this morning during the time indicated below. Mid afternoon weather for 9/27-overcast with light intermittent sprinkles. Temperatures are in the upper 50's to low 60's-which is about 12-14 degrees below normal for this day in September-BP 29.90"R along with light air movement from the NE at 3-8 mph. The next few days will feature a series of storms, the first of which (with an intense low pressure spinning off the West coast of the Queen Charlottes) will impact the Queen Charlottes, most of Southern BC, and Eastern WA, while the heaviest rainfall should arrive by sometime this evening over SW BC, Vancouver Island as well as over and West of the Cascades where as much as "4-8 inches are expected in the mountains and 2-3 inches around the Sound" along with the likelihood of strong winds. Interestingly, though snow does not pose a threat to pass levels (8000'), at the present time, the snow level is projected to reach a minimum level of only 4500' by Monday. Current conditions for 9/28-overcast with fog obscuring the higher peaks and ridges around the valley. The haze is light to moderate with little or no air movement. It is first from the WNW at 0-1 mph, then the North at 0 mph, wind puff: out of the NW to 6 mph, humidity 91% (yesterday, the reading was 81%), dew point 49°, current snow level is near 8000', observation time temperature was 48°, and the barometric pressure 29.75" and falling. |

Although 0.04" was received yesterday morning, another 0.04" was recorded later on for a grand total of 0.08". Yet another deep, intense as well as wet low pressure system will bring a strong cold front through most areas later this evening resulting in very windy conditions to many communities near this area with wind speeds from the "South at 20-30 mph, and gusts up to 50 mph". The passage of this cold front should result in lowering the minimum snow level to 4000' by Monday evening thereby enhancing the likelihood of significant snowfall for the central Cascades "from late tonight through Monday night". A "total amount of 1-2 FEET is expected by early Tuesday morning". Current conditions for 9/29-mostly cloudy (scattered Cirrus, Cirrostratus, Altocumulus, and Cumulus), no precipitation during the overnight, the haze is light with little or no air movement. It is first from the West at 6-15 mph, then the SW to 3 mph, wind gust: out of the West to 26 mph, humidity 67% {yesterday, the reading was 91%}, dew point 44°, current snow level is near 6000' [yesterday, it was near 8000'], observation time temperature was 46°, and the barometric pressure 29.53" and rising. |

Mid afternoon weather for 9/29-overcast (scattered Cirrus, Cumulus, and dense Cirrostratus) with brief, intermittent light sprinkles. Temperatures are in the mid to upper 60's, BP 29.48"R along with light air movement from the SW. While Western WA continues to be hammered with showers (the UW model is currently showing moderate scattered showers tracking East by NE over NW OR, over and West of the Cascades, as well as the SE portion of Vancouver Island), some of which may be "locally heavy", as well as windy conditions with sustained wind speeds of "15-25 mph, and gusts between 25-40 mph" is all due to low pressure now centered over the Queen Charlottes. In addition, with the passage of yesterday's strong cold front, the air behind it should be much cooler, and hence, lower the snow level from 5000' today, to a minimum level of 4000-4500' by tomorrow. As a result, 1-2 FEET are expected above 5000' while 6-12 inches are likely today, and an additional 5-12 inches by tommorow night according to the WSDOT. Current conditions for 9/30-partly cloudy {scattered Cirrus, Cirrostratus, Cumulus, and what appears to be "snow clouds" from the West to the SW} and cool. The haze is light to moderate along with some air movement. It is first from the West at 5-6 mph, then the NW at 6 mph, wind gust: out of the WNW to 36 mph, humidity 76%, dew point 43°, current snow level is near 5000' [yesterday, it was near 6000'], observation time temperature was 45°, and the barometric pressure 29.56" and rising. |
