Brief showers indicate subtropical moisture is abundant...at least at the surface. Record high temps everywhere. High pressure is anchored smack-dab over our location (1017mb/30.17 inches). The models for the next 72 hrs are suggesting little change. Typical El Nino behavior. The El Nino phenominan happens once or twice every 10 yrs. It disrupts upper air flows. A perfect indication of El Nino is the enormus shearing winds across the Caribbean & Atlantic wtrs this yr. Nearly every tropical system that did develop, upper-level troughing destoyed them. Troughing at the upper levels is another hint that may be in store for us come Feb/Mar of '10. If past history repeats itself, then get ready for stormy weather by then. The last El Nino pattern was about 11 yrs ago. We're over due. |

Very brief & quick moving showers as winds from the SW began to be on the increase. A series of cold fronts will be moving thru our location later today. I estimate around the dinner hr or later. Active convection will advect from a NW/SE direction. Some isolated cells could reach severe limits. Winds will be on the increase all day today & as low level moisture also advects NE. Temps behind the boundary are 10-15' lower. We can finally open our windows. |

Two converging weather systems, 1 approaching from the NW & the 2nd an old tropical wave advecting from the SW combined for a good round of moderate/steady rains. The front from the NW is expected to stall near the GA/FLA border region. The energy from this frontal boundary was mainly to our N/NE as Tornado Watch Red Boxes were issued near the same area earlier this afternoon. High pressure will eventually build in which will give us very hot & summer-like pattern by tomorrow afternoon. Record heat is expected & should have no problem setting new record highs for us. Summer does not want to end. |

Light sprinkles currently w/ on & off showers as Tropical Storm Ida passes NE of our location. Significant rains are expected tomorrow as Ida transitions into an extra tropical system & then becomes absorbed into a cold front. The Westerlies are then expected to pick up the remnants of Ida & carry her NE as a possible Nor'easter. |

The NC/SC/VA coasts were being battered by tropical storm force winds all day. Some lost pwr. The cold front that trailed Ida will pass thru sometime later this afternoon bringing much cooler & drier air for a few days. |

A line of moderate precip crossed my location just as the Bucs'/Saints' game ended. A narrow but slow moving band of rain advected very slowly SE-ward & vacated my location as the 2nd round of NFL games ended. The entire disturbance's origin formed just off the TX coast last Wednesday. It deepened slightly for 24 hrs but deamplified steadily over the next 72 hrs. I'm expecting many more of these types of surface lows in the coming winter as we are in an El Nino yr. This one lost energy before it arrived here. Feb/Mar should be very interesting indeed around here. Looking forward to it. |

The steady rains began around 10:30am & continued thru out the day. A deepening surface low currently located in the NE Gulf will track NE this morning & vacate the peninsula by early sunrise. A 2nd vigorous impulse is expected to support a developing surface low that should be centered about 150 miles SW of Naples. In addition, a stationary front located about 100 miles south of my location will is currently stretching in an E-W pattern. South of the boundary, a very warm & unstable air mass encases the entire southern region of FL reaching northward to the Naples/Ft. Myers regions. This entire air mass is expected to advect back northward as a warm front. This is where things may begin to get very interesting. A tornado watch red box has been posted for the entire region. |

The stationary front that was elongated in an E/W direction moved north during the early morning hrs. However, the front did not reach the Tampa/St. Pete region which kept my location cloudy, cold & damp. By midafternoon skies began to clear; much colder & drier air began to dig southward. It will be interesting to see what happens when the return flow arrives next wk. |

A powerful surface low has continued to deepen as it crossed to our NW. Will be converting into a Nor'easter w/ in the next 6 hrs & is expected to be a major winter storm for the Atlantic Maritime states including the DC area as this once closed-low will soon become obsorbed by the Polar jet as it quickly makes its northerly turn. (A very sharp "U" signature & almost even a "V" Polar jet track). The Senate is attempting to slam dunk our health care as they have been summoned to Capital Hill. Looks like God Himself is even attempting to stop this nightmare in the making! Most of the severe weather occured to our south & SW. Very cold Arctic air is being escorted by the Polar jet. Windy & much colder temps will be in store until the Arctic high vacates our region. The polar ridge is emmense. The ridge expandes out nearly 2200 miles in circumfrence! More to come as another round of severe weather may be in the offing in several days. |

Bands of light rain shwrs & sleet/freezing rain are tracking E/NE that are associated w/ the cold front that preceeds the very dangerous Arctic High. Winds are currently very light but are being advised of wind chill factors on Saturday. Bitter cold & blizzard conditions are in progress across the Central Plains & moving in the direction of the lower Great Lakes. Very cold & blustery conditions to remain w/ us 'till Monday. A gradual warm up will begin on Tuesday. Since we are still under the influence of the pre-frontal precip, it is still rather quiet. But if this frozen precip lasts longer than expected, it will be trecherous to attempt any driving. At 3:36 AM: freezing rain/sleet/light rain & 40 degrees. Freeze Watch for Saturday (which no doubt will be upgraded & expanded). Wind Chill Advisory for all of Saturday. |

Third night of sub-freezing temps in west/central FLA. The Arctic system which has gripped nearly the entire 2/3 of the contenintal US will losen it's stranglehold on the region slowly as the ctr drifts E/NE. The Polar jet retreats north & our dearly missed subtropical jet returns. Temps will begin to moderate tomorrow afternoon & gradually return to normal w/ hi temps reaching the mid 70s. This deep freeze has damaged the citrus & strawberry crop. We won't know for another few wks just what the approximate damage is. But from what I've seen so far it does not look very good. Watching for El Nino systems to return to our weather. Currently: clear & 33 degrees. Hard Freeze warnings 'till 9am tomorrow. |

The iron grip of the dbl-center Arctic High (via a very deep trough in the Polar jet) is gradually losing its grip on west/central FLA. The Polar jet, which drove so deep into the south reaching many regions of the Gulf coast...w/ even deeper troughing reaching as far south as Cuba, is retreating back northward. It will gradually be overtaken by the subtropical Pacific jet which has been so persistant due to the El Nino phenominan. It will be interesting to see what may happen Friday into Saturday because there will be several vorticy maximums riding along this river of air. There is a very strong chance that 1 or 2 of these impulses will separate from the subtropical jet & become isolated. Meteroligists refer these as "closed lows" which begin to take on an identity of their own. A warm sector should be in place when cyclogenises initiates late Friday/early Saturday. Models are also coming together in leaning toward a more active pattern. I'm calling for convection to be confined in the warm sector...specifically over the open Gulf waters on Friday & across west/central FLA early Saturday. There will also be a very noticable & very welcome burst of warmer & moderatly more huimid air. Good riddens to Arctic Blast 2010. |

After logging off earlier yesterday morning, there was additional precip measured. Fairly significant heavy rains no doubt. That front has vacated our region w/ drier air at the mid-levels. Decent amt of moisture at the surface mixing w/ onshore winds earlier created dense fog. Dense Fog Advisory issued 'till 9am. Pleasent weather for Saturday for once. Sunday should be interesting. Pre-frontal boundary of subtropical moisture mixing w/ the Polar Jet from Canada will destabilize the atmosphere for our location w/ potential squall line convection to be in progress. |

A very dreary day w/ overcast skies, chilly temps & occasional showers. The cold front which crossed my location this past weekend stalled across all of southern & southwestern FLA. This has now begun a northerly push as a warm front. Temps have gone up since this afternoon & so has the humidity. Fog has settled across my location. This will then be pushed back 1 more time as a cold front drives SE. This will push the stalled boundary back towards the southern & southwest FLA. Cooler & drier air will build in behind it & be w/ us for a few days. |

Pre-frontal precip was light to moderate. Most of the heavy weather was pinned btwn Lake Okeechobee southward to the entire southern tip of FLA westward over the Gulf. Some strong convection also was firing near the Lake Worth/Boynton Beach area. Actual front was well west of the precip area. Behind the front is a very cold air mass of Canadian origin. This will also be blustry as the southern belt of the Polar jet wraps around the southern most tip of the boundary. Winds are expected to be strong as this Polar high builds in to our region. Freeze Watch for later on tonight thru early Friday. This has been a very cold winter. |

A 50 mile wide swath of rain w/ embedded thunderstorms crossed my location during the late morning/early afternoon hrs. This band of rain is a prefrontal boundary of a cold front that is about 300 miles due west of here. The cold front does not have much cold air behind it. In fact, a quick warm up is expected by Tuesday & should last into the weekend. If history is any proof, I believe the winter solstice, w/ all of its cold air, is over for us...thank goodness.

Warm up coming by week's end & will be mostly likely the last of the cold winter west/central FLA will see. Watching now for moisture boundaries from the return flow as the high moves eastward. Long term models are picking up an increased moisture flow that will reach as far north to western NY state by mid-week. Indications are temps to reach low/mid 70s for that region. Be watchfull for any fronts to form as the stage is being set for a potential round of severe weather. More to come... |

Several unconfirmed tornado touchdowns in counties south & east of Hillsborough Cty. High moisture boundry continues to be in place across the entire west/central & SW FLA region w/ strong LLJ feeding into larger mesocyclone. Surface dew pt temps of high 60s/low 70s have yielded lift rates of 1000-1500 j/kG. Tornado Watch Red Box issued at 11:45pm yesterday replaced Severe Thunderstorm Yellow Box that was allowed to expire.

The combination of higher dew pts, a west coast sea breeze & a very moist boundary from a tropical wave advecting northward generated late afternoon/early evening thunderstorms. The convection was brief w/ echos of thunder coming from our SE. The storms were mostly rain makers; nothing has been reported from anything severe. More summer-like sea breeze storms & more numerous as the sub-tropical air mass continues to advect northward & interacts w/ a west coast sea breeze tomorrow. Some storms will be strong.

Severe thunderstorms were reported in Zepherhills & Plant City as the sea breezes collided near the I-75/I-4 corridor & pushed E/NE. Downdraft winds reached 77mph during a Zepherhills storm. No precip reported until later this evening when sea breeze & upper level energy interacted w/ each other which formed thunderstorms. We have had an active & unusual late Spring convective belt as ripples of energy has consistantly cross our state interacting w/ the sea breezes.

This was all that was left after a dying east coast sea breeze pushed thru. We have been under the domination of high pressure which has been expanding rapidly from NW to SE. Currently ctrd over Jacksonville, it will begin to shift a bit more to the E/NE. This high ctr has gradiants expanding outward in all directions & is very dry at both the mid & upper levels. Record heat for the 3rd time in 5 days as my location reached 98'. Moisture begins to return by late Sunday w/ evening sea breeze convection developing first along the west coast & then push east ward.

Sea breeze convection initially began as the west coast breeze pushed east w/ very heavy to severe thunderstorms taking place all across my location & thru out Hillsborough Cty. The west coast breeze was then pushed back westward w/ furious thunderstorm activity. Reports of hail, flooding & minor damage near MacDill AFB. Wind gusts of over 70mph was also reported near the Base. Our first day of summer. |

The east coast breeze was active since the late morning hrs. It was taking its seasonal SE-NW track but was very vigorous at times. The west breeze which looked lazy & slow began to push west much later & held its ground near the I-4/I-75 cooridor. Most of the heavy storms occured along that region & slowly began dissapating until now. I took a walk around the grounds & it stopped raining. Tomorrow another set up is in store for late afternoon/early evening hrs w/ both breezes active. Mostly cloudy conditions will break during the early commute later today w/ temps reaching the upper 80s early. The rains will keep us on the slightly cooler side...especially after heavy rains. A good 10-15 degree difference. |

Subtropical/torrential downpours occured during the normal late afternoon hrs but continued well into the evening. A non-tropical low ctrd about 150 mi south of the mouth of the MS is expected to track W/NW taking it onshore near New Orleans. Not a good situation as more oil is expected to propagate on shore making a horrible problem worse. Unfortunately more of the same tomorrow as tropical moisture continues to advect northward from the deep Caribbean & a very strong NW flow aloft will continue to influence our weather. 3 additional areas of interest in our region already & we are only 1 month into the hurricane season. Let's hope the weather holds out for the Celebration later today. |

Morning rains attempted to clear by early/mid afternoon as our holiday was mostly a washout. The non-tropical low that is still located about 100 miles south of the Mouth of the MS is expected to track W/NW. NOAA expects this to come ashore as a non-tropical system by later today. Abundant tropical moisture is being drawn across our peninsula which has continued to produce tropical downpours & thunderstorms. By later this afternoon we should begin to see some drying at the mid-levels as the low continues to move away. However, there are at least 3 areas of disturbed weather stretched across the Caribbean & the western Atlantic which may threaten our area by later this wk. |

Yet another round of afternoon convection which continues to be triggered by the non-tropical low ctr that is currenlty located just south of LA. This low is expected to pull away from our region taking w/ it the very rich tropical moisture which has inundated my location w/ large rain sums. Although this low currently does not have a closed circulation, it's a good idea to monitor any system that remains over the Gulf waters for an extended pd of time. It won't take much to get something going. Finally by late tomorrow, dry air located at the mid-levels & surface should lower our rain chances. We need a break from this monotinous pattern. |

We should have 1 more day of this pattern & then winds will be changing from the west to the SW. In addition, a weak tropical wave will be pushing northward tomorrow & Thursday which may add to the already unstable air mass. |

Brief shower generated by a SE/NW air flow only produced slight precip today. In lieu of a very strong easterly breeze, the air at the mid-levels are relatively dry. This will give us very humid & hot afternoons for tomorrow as only a slight chance of any measurable precip is in store. Record heat is expected tomorrow & should remain thru out the rest of the wk. |

Rain bands from Bonnie reached my work location just before mid-day. Although there were bouts of heavy rain in some of the bands, they did not last long. In fact, Bonnie's ctr was becoming more & more displaced from her heavy convection. It's been a nasty fight from the get-go. She has since been downgraded to a depression. Not much more is expected from her for the remainder of time btwn now & landfall tomorrow morning. |

There were 2 rounds of convective activity: the first occured when I was not at my location. This produced 0.40 inches of precip. The 2nd began late afternoon w/ vigorous cells tracking SE/NW. The second activity turned the outside to a very dark purple setting. There was a 3rd region of very active convective activity approaching at about 8:30 tonight. A very pronounced outflow boundary was easily noticable. The outflow region packed downdraft winds of about 45mph w/ higher gusts & vigorous lightning strikes. The cells, however, stalled & puffed down. More of the same later today as Bonnie disappates in the Gulf. |

There were several hundred lightning strikes from the storms & very long & deep thunder rolls which just missed us. The storms hammered Pinellas county. Very hot temps are contributing to active sea breezes from both coasts in addition to outflow boundary generation. More of the same tomorrow. Also, watching the tropics. |

Rain bands & squalls were the story today. As expected, TD 5 formed about 200 miles SW of Naples. 5 has a very large circulaion envelope as it gradually becomes better organized over time. The NHC has initiated coverage on 5 & have issued TS warnings for the entire LA coast for an expected landfall sometime on Thursday afternoon. Models are suggesting further strengthening w/ very good upper air support & very warm sea temps. There is 1 caveat: a large patch of drier air has been advecting into 5 which is due west of 5's "ctr". And thank goodness that it has. If for not that 1 variable, we could be looking at a much more dangerous beast. 5 is expected to become TS Danielle. And by the way the clouds are in motion looked in this morning's sky, it won't be long before that happens. It's even turning breezy. Rain bands w/ squalls for the morning hrs w/ a gradual improvement as Danielle-to-be moves away w/ a W/NW track. |

Morning rain bands moved quickly across my location & west/central FLA today as TD 5 circulation continued to move away. Surprisingly, at about 8pm the NHC issued a bulletin announcing that all tropical storm advisories for the southern Gulf states were discontinued. Additionally, it was determined that TD 5 was no longer a depression as its convection continued to deteriorate & its circulation become elongated & stretched. In spite of that, plumes of moisture will continue to advect NW which may bring occasional bands of rain which will be tropical-like. But most of the heavy rain threat has passed. For the upcoming weekend, it looks as if we will be returning to our typical afternoon & evening sea breeze thunderstorms. |

Only a few scattered rain patches left over from 5 as circulation still exists across my location. Most if not all precip features associated w/ 5 are now gone. We should expect our "back-to-normal" afternoon sea breeze activity. We have a very strong S/SW flow aloft which suggests when the west coast breeze intitates, it should advect E/NE. It should have no trouble reaching the east coast so I'm expecting most convective activity taking place over the east/central regions. Tropics are quiet. |

Very odd & very late sea breeze thunderstorms crossed our location & our northern counties. A combination of an active SE/NW breeze, a vigorous but rather tiny upper-level low which advected northward across our location, very warm...almost hot temps that were mostly pinned along our west coastline & beaches & very high dew pt temps in the upper 70s/lower 80s resulted in an explostion of convection. Some of the tops nearly reached 70,000 ft & unleashed over 5000 lightning strikes in a 90 min time frame as reported by police & fire teams in Crystal River & Cedar Key. Thunderstorms also dumpted over 6" of rain in those areas. Winds will be changing from the SE to the SW beginning later today & this pattern should remain w/ us for the next several days. So any convection that does develop will take place during the morning hrs & then push NE thru out the afternoon. |

It was a very active day in terms of convective activity however, most heavy precip remained to our north & south. Our location was influenced by a dry flow aloft which was cause by a small high currently located over the north/central Gulf waters. This high has been slowly drifting westward. This should increase our chances of convection for tomorrow into Tuesday. Also, the tropics are beginning to heat up & become active w/ several tropicals waves progged to eject out from the west Afrian coastline. In addition, Tropical Storm Daniella has just formed about 600 miles S/SW of the Cape Verde Islands. Not expected to threaten the US. |

Thunder was constantly a back-ground noise all afternoon. Heavy convection surrounded my location & we did rec' almost a 1/2 inch of precip as the storms finally reached us just after 6:30. Tpa Intl rec'd
1 1/4 inches of rain only 7 miles away & there were reports (WFTS-28) that the central counties rec'd large amts of rain. Areas of Lakeland rec'd over 5" of rain from training thunderstorms w/ knee-deep water in a 90 min time. That's a lot of rain in a short pd. More of same tomorrow as west/central FL is climbing the hill of tropical weather activity & plenty of moisture available. TS Danielle is gaining strength in the tropical Atlantic & is not expected to pose a threat to the US. Models are suggesting a NW track for the next 72 hrs & then a N/NW track is expected. Bermuda has been put on notice. By the time the N/NW track takes place, Danielle should be approaching C-2 strength. |

Lots of rain all around my location. I work in Pinellas Cty & it was a deluge of tropical downpours. As I drove eastward the heavy precip gradually subsided. Again, most of the heavy rains were taking place south of my location as it very slowly advected N/NE. Sarasota airport confirmed 4.40" of rain today...a record that blew away any past reading. As our morning turns to afternoon, morning convection will gradually vacate the area as the trough of low pressure that is attempting to reform over the Gulf will be moving away NE. Ridging will build from our S/SE & we should begin to return to a "normal" afternooon/evening sea breeze thunderstorms. An breaks in the overcast will cause temps to quickly climb to near 90. Hurricane Danielle is a C-1 storm over the east/central tropical Atlantic; should reach C-2 shortly. Earl-to-be is right behind Danielle. |

Nasty convective activity started the day as clusters of storms arrived on shore from the Gulf. Our region continues to be plagued w/ 2 systems interacting w/ each other & we are caught in btwn. Plumes of moisture continue to make their way across our state although I'm beginning to see this surface low over the Gulf begin to be pushed westward. Hopefully this will bring us some breaks in this non-stop rain event. |

Skies looked threatening again this morning. However, most precip remained to our south today. The low ctr that has been responsible for nearly 1 full wk of rain is slowly drifting west. The problem w/ this trough is it has a large circulation envelope; it is also being assisted by an upper trough parked off of the NC/SC coastal border region. Both have dumped alot of rain. Tomorrow we will begin to see a very slow transition to normal Summer weather patterns. |

Another round of heavy rain w/ thunderstorms advanced across our region as a very active east coast breeze collided w/ our west coast breeze near the I-4/I-75 corridor. A 2nd round pushed thru about an hr after our first round as a result of outflow boundries from previous activity. Both belts of convection produced heavy rains. A back door boundary which has been pushing from NE to SW should clear our location later tonight & escort drier air both at the surface & aloft. This will lower our rain chances & relative humidities for a few days. Watching Hurricane Earl approach the eastern Caribbean periphery threatening the USVI & BVI. Earl is a major hurricane w/ sustained winds of 125 mph & should reach C-4 status by early tomorrow. Earl is expected to come close to the US mainland (NC/SC/VA region) possibly w/in 100 miles of the NC outter banks Thursday or Friday. Fiona will be about 5 days behind Earl. |

It tried very hard to rain today but most of the activity petered out in our area. Further inland, heavy storms. The convection approached from the W/SW; tomorrow I think we'll see convection approach from the S/SE via a ridge of high pressure currently to our north will be shifting SE. This shift should redirect our winds from the SE to the NW. Any convection that does develop will approach from the SE during the later part of the PM. Currently watching 2 regions of disturbed weather in the tropics that have a high confidence of obaining closed circulations. In fact, I would not be surprised to see the region over the SW Gulf become our next tropical storm. Gaston is expected to reform & pass to our south. |

Eastward advecting sea breeze reached us late in the afternoon/early evening. However it was fairly tame as most of the heavy activity was produced east of my location; not much left when it reached us. A very similiar pattern is set up for tomorrow as a small high ctr is parked just NE of Jacksonville which is bringing our winds around from the SE to the NW. Plenty of subtropical moisture is available at the surface & at the mid-levels for convective development later this afternoon. Tropical Storm Hermine came ashore just south of Brownsville, TX last night & is dumping enormus amts of precip. More tropical waves are progged to eject westward from the Afrian coastline this wk. |

A repeat of the same for tomorrow afternoon w/ continued hot & humid conditions at the surface. Tropical Storm Igor lcoated over the central Atlantic is nearing hurricane strength & is expected to be a powerful C-4 storm by mid wk. Igor is not expected to to a threat to the US. |

A late afternoon east coast sea breeze in addition to an unstable atmosphere produced brief but heavy precip for my location. CGs also accompanied these fast moving westward clusters. Some areas received much heavier rain w/ some local flooding. However, most of the activity was hit & miss. Watching the tropics as TS Matthew heads inland over Belize. We may see a secondary low form over the south/central Caribbean by early wk or we may see Matthew circle around back into the western Caribbean waters. The guidance models are all over the place in their potential outcomes. Scattered precip again for tomorrow. |

Traces of late convective activity made its way across my location as a pre-frontal precip boundary advances from the NW. This is expected to wash out & become elongated. The southern sector remains warm & very tropical-like while north of the boundary is somewhat drier. A repeat performance is expected tomorrow. Currently watching the NW Caribbean as Invest 96-L has been designated by the NHC. Pressures continue to fall in the region in the wake of Tropical Storm Matthew.

That entire region is under tropical storm warnings from TD 16 born yesterday morning. 16 is currently located just south of the Isle of Youth & should be crossing central Cuba right now. Tampa dodges yet another hazard. |
