(Took 7 tubes of hot water to melt for precip value.)
2/7/2014 10:40 AM 0.13 2.6 0.12 12.0 2.38 26F, 98% OC (sun just poked through as storm quit), 5>10SE, no frost on inner/outer tube walls. Stronger winds 3 hrs. earlier caused lateral-blowing snow here, white-out conditions in Jackson. (For that reason, suspect ACTUAL new snowfall to be around 4".) Mts. visible as high as top of Munger, but Teton Village, Grand still hidden. Ground accum. reflects LOT of ice, holding that frozen water near base of sample, but total of 2.38 is accurate (took 6+ tubes of hot water to melt). Not snowing currently.
2/8/2014 11:00 AM 0.53 5.0 0.53 12.0 M 37F! 100% overcast (neither Munger Mt. nor ranges to SW, W, nor NW visible), calm. Snow accum on ground reflects some compression from weight of warmer snow melting, but also nearly 1" of icy snow at ground surface.
2/9/2014 8:00 AM 0.33 4.0 0.32 18.0 2.23 37F, 100% overcast, surrounding mts. except to east and Munger to south hidden in fog/snow cloud, calm, no frost, not precipitating. With 18" of snow on ground to compact in 12'tube, had to chop adjacent opening, enabled viewing of app. 1" icy snow at ground level (inc. in measurement). Note all 4" since 11 a.m. 2/8--corrected that report, which had showed incorrect P.M. sample time, instead of correct a.m.
2/10/2014 10:00 AM 0.00 0.0 0.00 18.0 M 27F--DOWN from 32 at 7:00 a.m., but skies only partly cloudy, so sun should warm things up. LOT of snow/ice sliding off sloped roofs (especially metal). 5-10S, not precipitating. No overnight snow at all, no frost.
2/11/2014 7:30 AM 0.00 0.0 M M M 27F, calm, 100% overcast, not precipitating. Temps in low 40s yesterday caused much loss of snow on steep roofs--used snowblower to clean plan deck four times during afternoon--while ground snow consolidated its moisture content.
2/12/2014 9:45 AM 0.11 1.5 M 18.0 M 30F, 100% overcast, 5-10SSE, snowing and blowing. Very difficult to get accurate measurements today--board had 1/2", tube had .07 of snow--on top of .04 ice, for total of .11. Ground accum anywhere from 15" to 20" (for estimated average of 18" but did not do core sample).
2/13/2014 10:00 AM 0.32 0.0 M 18.0 M 41F, 100% overcast with mts. to SW, W, and NW entirely hidden, Munger and mts. to SE, E, and NE partially hidden with fog/snow. Gusting winds 5-10S, not precipitating. Lot of water puddling on streets and driveways, lot of snow sliding off metal roofs all night long and this morning.
2/14/2014 9:00 AM 0.02 0.2 0.02 16.0 M 28F, 100% overcast, <5S, snowing very lightly. Temps yesterday afternoon in low 40s caused significant melting--Staples parking lot in Jackson was half-flooded with up to 18" (est.) of water, LOT of streets and parking lots with ~12" of slush, making driving difficult. Snow accum in yard shrunk to 16" and temps in mid-high 20s overnight consolidated it, resulting in crusty surface this morning with icy contents down to ground, where 1" layer of ice (essentially) remains.
2/15/2014 9:15 AM 0.57 0.0 M 17.0 3.90 35F, 100% overcast, ~5S, not raining/snowing, but see snow/fog on western mountains. Lot of slushy snow/ice on streets, driveways. Took 7.01" of hot water to raise temp of 17" snow on ground (10.91" compressed into tube) to 40F for determining water content--now mainly icy snow (good for snowballs!) on ground, fairly consistent from top to bottom. Cutter Races in Jackson today--should have some good snow on track.
2/16/2014 9:00 AM 0.11 0.0 M M M 35F, 100% overcast, 5-10S, steady rain, surrounding mts. hidden in fog/snow (just the base of Munger visible). Rain began late p.m., continued all night.

Ground sample does NOT include app. 1/2" of ice at ground level--just 21" loose snow. (Tube snow had to be compressed, thawed with 5.03" of hot water from sink, then reheated in microwave--9.57" melted, less 5.03" added=4.84")
2/24/2014 6:40 AM 0.00 0.0 M 20.0 M 36F, 5-10S, partly cloudy, not precipitating. This was the first night in recent ones when the overnight temp (apparently) remained above freezing all night. 34F at 11 p.m., 36F at 6:30 a.m.

3/2/2014 8:15 AM 0.56 7.7 0.55 28.0 M 31F, 100% overcast, <5S, very lightly snowing. Lot of snow slid from roofs last night as temps hovered around 33F. Snow on ground and board is heavy and wet. Surrounding mountains (SW,W,NW not visible from Rafter J, but Munger (S) visible but showing snow/fog. Of gauge total, all but 1.75" (.26") was recorded after previous report (3/1). Due to continuing snowfall, took a sample at 3:30 p.m., which showed 6.0" on board and in gauge (.30" core), 28" on ground.
3/3/2014 1:00 PM 0.20 M 0.20 M M 35F, calm, not precipitating. Appeared to have about .25 inch of new snow last night (unevenly distributed), but only liquid water in tube.
3/4/2014 9:30 AM 0.20 0.0 M 17.0 M 41F, calm, light 100% overcast--western mountains not visible, ones to south partly visible (Munger 10% hidden in snow/clouds. Not precipitating. LOT of melting over past 36 hours of ground snow--now at 17" in same yard location we had 28" (max) only four days ago). Ground snow very crusty, heavy, with grass visible in some areas where we shoveled paths. Snow almost gone in subdivision streets--still piled up on sides to heights reaching 5-7 feet.
3/5/2014 7:15 AM 0.23 2.8 0.23 20.0 M 29F, calm, 100% overcast, surrounding mountains (S,W) now visible. Not precipitating. Storm started around 10 p.m., had ended by 6 a.m., leaving lot of ice on vehicle windows, covered with from 1-3" of snow. Subdivision streets appear clear. Lost a ton of snow yesterday from melt with temps in high 30s, low 40s.
3/6/2014 10:15 AM 0.14 M M 16.0 M 33F, ~10SE, 100% overcast, lightly raining (with some snow mixed in). Rained began before midnight, seems to have continued all night. Munger visible, but all mts. to SW, W, NW hidden in fog/snow. Lost a lot of snow in yard overnight, many places (where shoveled) bare.
3/7/2014 7:20 AM 0.23 0.1 M 16.0 M 32F, calm, 100% overcast, not precipitating. Both flake and pellet snow scattered on board (and deck) but immeasurable. Tube had both water and ice.

3/11/2014 9:00 AM 0.02 0.2 0.02 13.0 1.29 33F, <5SW, 100% overcast, VERY lightly snowing in valley, but see more falling on upper elevations of Munger Mt., surrounding Tetons. Ground snow EXTREMELY icy, crusty, and melt value may be understated due to difficulty in getting surface-level ice into tube. Best guess.

3/13/2014 8:00 AM 0.00 0.0 M M M 14F, calm, clear, frost not quite as hard as yesterday, expecting continued melting of ground snow, increasing percentage of water (ice) by volume due to the freeze/thaw cycle with warmer temps (40s) during the day, colder (mid-teens) as night.
3/14/2014 7:45 AM 0.00 0.0 M M M 16F, calm, clear, light frost, continued melting of ground snow accumulation expected today as temps climb into 50s again.
3/15/2014 9:00 AM 0.07 0.3 0.07 11.5 M 30F, <5NW, 60 per cent overcast, not precipitating. Snow began around 7 p.m. 3/14, had ended by early hours of this morning--icy, crusty, leaving layer of ice on windshields this morning. Due to warmer day temps, night temps in mid-teens to mid-20s, ground snow continues to disappear in valleys, leaving very icy deposits. (Will have a core melt value of remaining ground snow on 3/17.)

Ground accum of snow VERY crusty--almost solid ice at grass level, making it very difficult to retrieve, but 12.5" of ice/snow reasonably accurate. Heated over 9 tubes (equivalent) of water in microwave to melt 12.5" of ice/snow in tube in order to determine melt value.
3/19/2014 9:30 AM 0.00 0.0 M 11.0 M 22F, calm, 10 per cent overcast. Light frost this morning.

Fog/snow visible on surrounding mountains, but Munger (south)is 90 per cent visible, snowing top to bottom. Ground accumulation is VERY crusty (took 2.98" of hot water to reduce ice/snow in 4" collector tube to 1.68" of liquid water.
3/28/2014 9:30 AM 0.04 0.7 0.03 6.5 M 32F, 100% overcast, 5-10SE, not precipitating. After the melt-off of essentially all snow from the 3/26-3/37 storm, had another overnight that covered bare ground and yard snow, but left streets clear.
3/31/2014 11:00 AM 0.15 M M M M 33F, calm, partly cloudy, occasional sun, occasional snow flurries. Tube contents consisted of mainly ice, some water (from evening rain).
4/2/2014 9:15 AM 0.11 1.8 0.10 1.8 0.10 31F, mostly cloudy, with strong sun shining through, calm, good visibility of mountains (Munger clear). Due to wide differences in snow depth from bare to 6-8" in yard, new ground accum reported as same as on board--slightly less than in tube (which was estimated, due to slope of snow).
4/3/2014 9:00 AM 0.00 0.0 M M M 25F, calm, clear, not precipitating. All of yesterday's 2' snowfall (by 4/2 a.m.) had melted off ground by late afternoon. Fairly heavy frost this morning.
4/4/2014 9:30 AM 0.00 0.0 M 3.0 M 28F, <5S, 100% overcast, lightly snowing (large flakes). No precip last night, but started snowing here (2 mi s of Jackson) around 8 a.m.--tube has about 1/4' snow so far (but am not emptying it at this time). Lost more ground snow yesterday afternoon. (3.0" is guess at overall average, including bare spots.) No frost this a.m.
4/6/2014 9:30 AM 0.03 0.2 0.02 0.5 M 30F, calm, 100% overcast, not snowing. Ground cover is spotty (not solid snow cover), and will be melting--already is. Perhaps .1 of tube contents resulted from previous storm drop left in tube yesterday as snow continued falling (for about 15 minutes).
4/7/2014 8:00 AM 0.00 0.0 M 0.0 M 25F, calm, partly cloudy, not precipitating. Hard frost this morning. Over the past 24, brief periods of flakey snow that did not cover the ground, amount to any accumulation in tube. By area, remaining snow in yard amounts to only about 20-25 per cent (mainly piles heightened by snowblower snow clearance).

Rain occasionally mixed with quickly melting snow.
4/27/2014 10:00 AM 0.34 0.3 M 0.5 M 34F, calm, overcast, not precipitating. This morning, had snow covering (app. .5 inch) for first time in many days. Began with rain yesterday afternoon--emptied tube at 4 p.m., had .29" of water accumulated since tube was regularly sampled earlier in the day. Began snowing lightly around midnight. Today tube contained .05"--added to .29" for the .34" shown as having fallen since yesterday morning's sample.

6/13/2014 8:00 AM 0.02 M M M M Resulted from passing thunderstorm last night that seems to have almost missed area south of Jackson, although it was spread over several hours (ended around 11 p.m.)
6/17/2014 8:00 AM 0.34 M M M M Rained almost all night, starting around 11 p.m., ending unknown. Currently overcast, with low-hanging clouds fogging upper half of surrounding mountains. Apparent low was around 39--although potential for frost had been forecast. Good, soaking rain was badly needed to green up lawn grass that had become brown.
6/18/2014 8:30 AM 0.03 M M M M Low this morning of 35, so no frost, but light dew, and brief period of rain that was mixed with snow in Valley (10 minutes), no accumulation. No precipitation since 8:30 a.m., but surrounding mountains from mid- to top are covered in threatening clouds, with new snow obvious on mts.
6/19/2014 6:30 AM 0.08 M M M M 34F, 100 per cent overcast, calm, no frost this morning, but covering of dew. Fresh snow on surrounding mountains. Had rain yesterday morning and afternoon, with light hail REPORTED in Jackson.
6/24/2014 7:00 AM 0.00 0.0 M M M 47F, calm, skies clear, birds singing, bees buzzing, grass growing, a fine time should be had by all.
6/26/2014 2:15 PM 0.88 M M M M Brief light rain this morning around 6:30 a.m., but since it looked like we would be getting more, waited until 2:15 p.m. to empty tube--following 15 minutes of HEAVY rain. Still falling lightly, hearing thunder to SE, but seems to be clearing there.
6/27/2014 11:00 PM 0.33 M M M M After periods of rain all day, decided to empty tube a second time at 11:00 p.m. to avoid overflow during the night. First emptied at 10:45 a.m. today (.04), second empty at 11:00 p.m. (.29), accounting for today's total of .33.
6/28/2014 10:00 AM 0.22 M M M M cloudy but some sun. cool, light breeze. Measured precipitation all fell after 11 p.m. (emptied early to avoid overflow of tube if continued rain last night).
7/12/2014 8:00 AM 0.02 M M M M Brief storm during past 24 hours.
7/13/2014 7:00 AM 0.06 M M M M Calm, clear, 47F,had one of the thickest fogs this morning that we have had in months, perhaps years, with humidity at 80% and heavy layer of dew, following storm late yesterday afternoon with extended periods of high winds--feared for a couple of dead aspens in yard.
7/14/2014 7:00 AM 0.00 0.0 M M M 47F, calm, light overcast, fairly heavy dew but no fog visible during sampling period.
7/16/2014 11:45 PM 0.07 M M M M This precipitation fell AFTER 7:38 p.m. on 7/15, when I submitted a "Significant Weather Report" after a storm passed through Teton County, dumping .13" of heavy rain, pea-sized hail, and high winds. After a lull of about 10 minutes, a second, lesser storm occurred over about 15 minutes, during which .07" of rain was captured in the tube. Total for the 24 hours after first report on 7/15 (morning) through 7/16 a.m. was therefore .20".

7/29/2014 7:45 AM 0.00 0.0 M M M 100% overcast, with storms clouds threatening to drop some rain today. Saw rain on the mountains to SW Monday afternoon and had a FEW drops in valley--not enough to register in tube.
7/30/2014 6:45 AM 0.12 M M M M Precipitation from storm that blew through yesterday afternoon from SW.
8/4/2014 6:30 AM 0.33 M M M M First time this was checked since last Wednesday, due to trip to Ohio. Returned Sunday night, but gauge was not emptied until 6:30 a.m. Monday morning, so that constitutes the total precipitation for the entire period. Probably should have been filed as multi-day, but this is being reported from Ohio, on mobile.
8/5/2014 5:30 PM 0.25 M M M M Amount of rain that fell between 6:0 p.m. 8/4 and 5:30 p.m today, with .09 falling before 6:30 a.m and .16 falling today.
8/13/2014 8:00 AM 0.13 M M M M Thunderstorm passed through Rafter J subdivision south of Jackson between 11 p.m. and midnight. Heard a few claps but saw no bolts.
8/14/2014 7:55 AM 0.20 M M M M Storm occurred between 11 pm and midnight, then again in the pre-dawn/dawn hours today. No documented evidence, but this seems to be the most accumulated rain for the month of August that we have had in Rafter J since moving here in 1984--and the month is only half over!
8/15/2014 8:00 AM 0.01 M M M M
8/16/2014 8:00 AM 0.02 M M M M Couple of brief showers. Currently foggy.
8/21/2014 12:00 PM 0.30 M M M M Was still raining this morning (started around 11 last night), so I delayed sample until this storm had apparently stopped. Now just 100% overcast, cool.
8/22/2014 7:30 AM 0.14 M M M M 100% overcast, currently not raining, but had periodic light rain throughout the whole night--had to empty gauge early last night to avoid overflow from last night's significant storms. (Had .90 last night.)
8/23/2014 8:30 AM 0.01 M M M M 100% overcast, cool. Had no storms during the early morning hours, but it is just beginning to rain(very lightly). Surrounding mountains (S,W,N but not so much E) are mainly obscured by fog--but fresh snow IS visible atop mountains to SW. (The "S" word is coming!)
8/24/2014 8:00 AM 0.03 M M M M Rain occurred late yesterday afternoon, early evening. Cool this morning with half of mountains covered by fog, mostly cloudy. Seems to be clearing--maybe we will get a chance to catch up, mow some of our yard!
8/25/2014 8:00 AM 0.06 M M M M Overcast, cool, Munger Mt. and those to SW, W, NW completely hidden in fog.
8/26/2014 11:30 AM 0.05 M M M M Foggy all morning--reaching the base of Munger Mountain and all other mountains to SW, W, and NW.
8/31/2014 7:00 AM 0.10 M M M M Appears to have rained all night, after slightly heavier (but brief) storm late yesterday afternoon. Not raining at the moment, but 100% overcast, feeling of more rain to come this morning.
9/1/2014 11:00 AM 0.05 M M M M Heavy fog this morning, surrounding mountains were completely hidden thru mid-morning.

9/21/2014 7:00 AM 0.00 0.0 M M M Partly cloudy, patches of fog (over Snake River), typical fall morning.
9/28/2014 9:30 AM 0.35 M M M M Continuing intermittent rain has added another .35 since filed last report just after midnight (.91). Moderately heavy at times. 100% overcast with some ground fog.
9/29/2014 6:55 AM 0.41 M M M M Intermittent rain all night, moderately heavy at times but generally just light. At this point, it has been raining so much that the ground is highly saturated, with standing pools of water, noticeably higher levels in small creeks in this area. Great for late-fall grass, though--which is usually brown due to lack of moisture and natural reduction of chlorophyll production. About half of the aspens in this area have dropped their yellow leaves--which normally turn brown or russet prior to dropping. Have been seeing some spectacular low-level cumulus clouds and extensive ground fog in both early mornings and later.
9/30/2014 7:00 AM 0.18 M M M M Sampled this morning before leaving for the day but am recording now (5 p.m.)--was some additional rain between 7 and 8 a.m., further rain all day today (intermittently). Patches of fog on mts. Ground is saturated, seeing puddles where a week ago grass was brown and dying.

9/29/2013 10/01/2013 9:00 AM 3 0.05 M M Most of this minor amount of precipitation seems to have fallen very intermittently yesterday morning. Presently, mostly cloudy and calm south of Jackson, 38 degrees--about 10 degrees cooler than yesterday. We continue to have an extraordinary number of toadstools and "mushrooms" popping up in our yard--but not all in the same location as previous ones.
9/30/2013 10/04/2013 12:20 PM 5 0.34 2.0 0.20 This report follows the submission of my report of an unusually extended (12-15 minutes) hail storm, and consists of BOTH rain and snow. Over the past 24 hours, measured .07 inches of rain, which must be added to .27 recovered earlier in this period. Also, snow began last night at about 10 p.m., continued through about 7 a.m. today, producing 2.0 inches on the ground and my board. The core precipitation of that board snow converted to .20 inches of water. (I was unable to catch any snow in the tube, since I still had the rain funnel on it, and that prevented any snow from falling into the tube. (No snow caught by the funnel appears to have melted and added to the .07 inches of rain caught over the past 24. All snow is likely to melt with expected higher temperatures, and I am going to put the funnel back on the tube, to catch rain. (Whew.)
10/6/2013 10/07/2013 12:00 PM 2 T M M All precipitation in the form of melted frost.
10/9/2013 10/13/2013 10:00 AM 5 0.16 M M Currently 34, overcast, mix of rain and snow, watery ice and snow on ground, but no solid covering. Surrounding mountains 80-100% hidden by fog and snow (lower 100 feet or so visible). Two previous mornings had moderate-heavy frost (esp. Friday), depositing a trace of precipitation in tube.
10/15/2013 10/17/2013 7:00 AM 3 0.03 M 0.03 25 degrees, calm, frost--virtually the same as 10/16. Accumulated precipitation consisted mainly of tail-end of rain 10/14 and morning frost.
10/18/2013 10/21/2013 7:00 AM 4 0.00 M M Continuing cold mornings 24 (yesterday at 7:00 a.m. but only 17 a half-hour later on Mormon Row north of Kelly), with slightly warmer temps in mid-afternoon followed by fairly rapid chilling in early evenings. No tube accumulation but moderate frosting each morning leaving some moisture on the ground. Fall colors persisting around Jackson (no russet majority of trees yet) but many aspens have shed leaves. Only visible snow is at mid-mountain and higher elevations on the surrounding mountain ranges, including the Tetons.
10/22/2013 10/26/2013 12:00 AM 5 0.00 M M Continuing trend of no precipitation, lows around 24F, highs in 40s and 50s, moderate to heavy morning frost, clear to partly cloudy skies, calm to low winds during this period.
11/13/2013 11/15/2013 9:30 AM 3 0.04 0.0 0.04 All precipitation in this report was measured as water at 7:30 a.m. on 11/14. Morning frost has been light-moderate this period, skies partly cloudy, only snow left on ground at this elevation is clumps that slid off saltbox roof.
11/22/2013 11/24/2013 7:00 AM 3 0.00 0.0 0.00 7F, calm, clear, no precipitation. Heavy morning frost this period.
11/25/2013 11/28/2013 8:15 AM 4 0.00 0.0 0.00 18F, calm, clear, heavy frost with a few low-lying (roof-top) clouds. No current likelihood of precipitation, but have seen several wild turkeys already this morning, running for any available shelter.
11/29/2013 11/30/2013 8:00 AM 2 0.00 0.0 0.00 Mostly cloudy, some moderate frost today as yesterday, not precipitating currently, none expected.
12/13/2013 12/18/2013 8:00 AM 6 0.00 2.0 M Past several days have been warmer than previous few, both at night and during day, with slow melting of ground snow accumulation. Skies have been generally clear, winds calm, very little morning frost.
12/20/2013 12/23/2013 10:00 AM 4 0.50 3.0 M 34 degrees, wind 5-10, 100 per cent overcast, see clouds over mountains to west (front moving in), but only very light (Trace) of snow this a.m., remainder of reported .5 inch fell mainly on 12/20 and 12/21. Has been some minor melting on decks, streets past two days.
12/26/2013 12/29/2013 7:45 AM 4 T 4.0 M 3F, calm, overcast hazy sky with low-lying fog--surrounding mountains hidden. During this period, morning, daytime, and evening conditions generally the same, with clear skies, calm, cold prevailing.
12/29/2013 12/31/2013 9:00 AM 3 0.20 4.5 1.08 30F, 100% overcast, winds <5SE, lightly snowing. All snow during period fell after 11 p.m. 12/30. Upper half (or all of) Tetons currently shrouded by fog/snow, but Munger Mountain entirely visible from Rafter J, along with lower half of mts. to SE. Core measurement reflects continued concentration of ice at ground level, under accumulated snow.
1/2/2014 1/03/2014 9:00 AM 2 T 5.5 1.20 31F, 6-10SE, 100% overcast with Tetons largely hidden, upper halves of eastern and southern mts. likewise, except Munger Mountain still visible. Light snow falling--pellets, app. 3/32d to 1/8 inch--and seems to be increasing. Lowest 1/2" of snow on ground still icy, accounting for most of water in tube sample (above).
1/6/2014 1/07/2014 7:00 AM 2 T 5.5 M 5F, calm, too dark to view sky. Continued period of cold overnight temps (-5 > +5), with morning temps in low teens, afternoon highs 25>30, keeping ground snow from melting (esp. 1/2" ground layer of ice), some morning fog.
1/11/2014 1/12/2014 9:00 AM 2 1.00 8.5 1.74 28F, 100% overcast, 5-10SE, not precipitating at present. Tube sample included both solid ice and flake snow. Tube contained 3/4" snow/ice, melted to .16. Some drifting over past 48 hours.
1/13/2014 1/16/2014 7:00 AM 4 0.30 6.0 M Clear, calm skies this a.m. for setting full moon. All multi-day precip all measured on 1/14 a.m., with remaining days dry. Warmer afternoon temps on 1/15 caused significant melting of ground snow. Will sample several sites tomorrow a.m. to get reasonable average, core precipitation including the ground-level ice under snow, which has been declining.
1/30/2014 1/31/2014 8:30 AM 2 3.50 9.0 1.39 20F, calm, p. cloudy, light frost, no precip currently. Almost all snow fell between 7 p.m. 1/29 and 9 a.m. 1/30. Wind (5-10)from S/SE may have caused some distortion in actual snowfall in tube and on board (suspect, from ground accum, we had 1-1.5" on top of 3.5 captured. Tube at 12:30 p.m. on 1/30 had 2.1" (.32) and board had 2.5" (.32) while 9." on ground had 1.37--bottom half-inch or so remains base layer of ice formed prior to subsequent snowfalls and is included in 1.37" reported.
2/20/2014 2/21/2014 9:30 AM 2 2.70 21.0 M 28F, 95% overcast with sun trying to pop thru, snow/fog concealing all of mts. to NW, W, SW, but lower half of Munger visible. <5W. Tube core was .22, almost all of which fell after 8 p.m. 2/20. Slope of snow in tube indicated significant winds during night. Ground accum icy--had to thrust (almost hammer) my yardstick to reach the ground.
2/27/2014 3/01/2014 9:45 AM 3 4.00 22.0 0.59 31F, 100% overcast, calm, still snowing from start last night around midnight. Ground accum. had several thin layers of ice between top and bottom, came out to 4.22" of water. Bd. had 4.7" with .43 water, new snow in tube (4.0") had .59 core precip. Driveway has app. 6" of wet snow, while STREET has around 8.0" --discrepancies probably due to gusting winds (which were observed around midnight and probably continued). Midnight temp of 33F was duplicated twice during the night (woke up with leg cramps!) and was still 33F at 7:00 a.m., then fell to current 31F--ideal for continued wet, heavy snowfall in these here parts (28-32F). Welcome back to winter in Jackson Hole!
3/24/2014 3/26/2014 9:00 AM 3 0.00 6.0 M Continued daytime temps in 40s, 50s, and nighttime temps above freezing is causing a rapid melting of ground snow cover, ranging from bare ground over extensive area to as much as eight inches (excluding piled snow), with estimated average of 6". Most snow highly compacted and crusty.
3/29/2014 3/30/2014 7:15 AM 2 0.05 4.0 M 35F, calm, light rain falling, 100% overcast with surrounding mountains mainly hidden, along with just top 10% of Munger Mountain. All precipitation over past two days appears to have been in form of rain--no snow. Extensive melting of ground snow yesterday afternoon dropped total by about 20-30%, with about one-third of yard now uncovered.
4/9/2014 4/10/2014 7:15 AM 2 0.00 0.0 M All snow in yard (except quantity that slid during winter off our saltbox-style metal roof, accumulated and compressed) melted a few days ago. No rain, no frost, no hits, no runs, no errors. Light overcast, calm, 32F (down from 50s at 11 p.m.)
4/11/2014 4/13/2014 5:00 PM 3 T 0.0 0.00 Light snow this morning--no measurable accumulation, none previous during this multi-day period.
4/15/2014 4/17/2014 6:00 AM 3 0.20 0.0 0.02 All precipitation fell 4/15 a.m. as rain/snow mix. Left ground (but not streets, driveways) covered, but almost immediately melted.
4/18/2014 4/20/2014 8:30 AM 3 0.00 0.0 M
4/21/2014 4/25/2014 11:00 AM 5 0.19 M M Lightly raining (occasional rain/snow mix), 33F, calm, 100% overcast, visibility limited to Valley floor--surrounding mountains (half of Munger Mountain and above) hidden behind probable snow clouds, fog.
4/29/2014 4/30/2014 8:00 AM 2 0.00 0.0 0.00 Past two days of medium to heavy frost, with morning temps in mid-20s. Yesterday had very thick fog covering of surrounding mountains, including Munger to its base, and fresh snow at higher elevations. Skies clear, calm, no precipitation in sight.
5/12/2014 5/18/2014 7:15 AM 7 0.12 M M Light rain 24-36 hours ago has been the only precipitation during period. A few mornings, had mild frost.
5/19/2014 5/21/2014 5:00 PM 3 0.03 M M fell over the past 24 hours.
5/23/2014 5/25/2014 11:00 AM 3 0.12 M M storm late yesterday afternoon.
6/4/2014 6/07/2014 7:30 AM 4 T M M Only moisture in tube appears to have been VERY light dew when morning temps approached freezing (but did not get below 33). Enough to zap two pepper plants, however! No actual frost seen during period.
6/8/2014 6/12/2014 9:30 PM 5 0.02 M M Hearing thunder to the SW, expecting some significant rain, so I'm closing out this relatively dry multiple day precipitation report. (Slight amount of rain in afternoon three days ago. Since then, have had only dew in mornings.)
6/14/2014 6/16/2014 12:00 PM 3 0.05 M M Anticipated frost this morning, but low was 41degrees. had rain yesterday, amounting to .05 by 12:00 p.m.
6/20/2014 6/23/2014 6:30 AM 4 0.05 M M 39F, calm, clear, dew this morning. Couple of brief showers in this period, including two or three thunderclaps on 6/22--no lightning observed. No frost during period (not even any snow!)
6/29/2014 6/30/2014 7:00 AM 2 T M M Trace amount left over from tail of storms on previous report. Skies this morning 95% clear, 41 degrees, calm.
7/1/2014 7/03/2014 8:00 AM 3 T M M Mostly clear, calm. Since we have had no recent storms or showers, slight amount of water in tube MAY be from dew/very light frost on 7/1.
7/4/2014 7/08/2014 7:30 AM 5 0.05 M M Calm, clear, cool--collected entire measure of precipitation on one day of the period reported, during brief storm passing over area.
7/9/2014 7/11/2014 7:00 AM 3 0.04 M M Precipitation captured during early morning hours of 7/10 as a couple of minor storms passed through area.
7/17/2014 7/20/2014 8:15 AM 4 0.07 M M Most of precipitation during this resulted from brief, light showers on 7/18.
7/22/2014 7/27/2014 7:15 AM 6 0.02 M M Reporting this accumulation but doubt the accuracy, unless a light storm came through during the night, since it did not rain in daytime hours. MAY have gotten the overspray from watering flowers and vegetables.
7/31/2014 8/04/2014 6:30 PM 5 0.33 M M Most of this period's precipitation appears to have been the result of a storm this afternoon. Tube had not been emptied since 7/30, due to observer's trip to Ohio, returned late Sunday night.
8/6/2014 8/12/2014 10:00 AM 7 0.54 M M Back from a 4,895.4-mile driving trip to Ohio for my 50th HS reunion, a wedding, a house-hunting trek, and an unsuccessful search for a new puppy. The accumulated total reflects daily samples of .16 @ 0700 on 8/6, .07 @ 1800 on 8/6, .04 @ 0700 on 8/7, .01 @ 1800 on 8/7, .11 @ 0700 on 8/8, .15 @ 1800 on 8/8, and a trace on 8/9, with NO precipitation on 8/10, 8/11, or 8/12. Hope all of our observers in Teton County are doing well--feel free to email me if you need any new equipment or reporting help.
8/17/2014 8/20/2014 9:00 AM 4 0.14 M M Precipitation in the form of an unknown number of brief showers last night and early this morning (before 6 a.m.). Currently 90% overcast, with clouds down below tops of surrounding mountains, more showers likely.
8/27/2014 8/30/2014 7:30 AM 4 0.01 M M Light overcast following a brief shower around 11 p.m. last night. Have had ground fog each morning of this report, up to 100 or so feet above ground, but no precipitation until yesterday.
9/2/2014 9/08/2014 7:30 AM 7 0.07 M M All but .02 of the precipitation during this period of mainly cool temperatures but little rain fell of the past 16 hours. Currently not raining, but heavy fog restricting visibility to only a couple of hundred feet.
9/11/2014 9/19/2014 7:00 AM 9 0.38 M M Currently heavy fog in valley south of Jackson, visibility only a couple of hundred feet. Rain that began yesterday afternoon continued at least through midnight.
9/22/2014 9/23/2014 6:40 AM 2 0.61 M M Sample collected at 10:00 a.m. 9/22 (not reported) was .25. Continued to rain intermittently all day yesterday, lightly to fairly heavy downpour at times, totaling .36 by this morning. Not raining at this time.
