We had extremely high winds, with several hours of sustained winds over 25 km/h. Extremely low barometric pressure (994.6 hPa) observed at 2330, followed by rising pressure. I estimate the rain probably stopped half an hour later, based on experiences with previous storms.

1/6/2010 7:00 AM T T T M M Snow flurries again for most of the morning after ~0730. It sure looked pretty when patches of sunlight illuminated the gently falling, large flakes. They looked like diamonds falling from the sky. Deer have been coming out to graze on the field and we see they have developed dark winter coats on their backs.

1/8/2010 7:00 AM 0.05 0.8 0.05 M M Snow started with air temperature at +0.7 °C and ended at an air temperature of -0.13 °C. It fell in two waves, mostly consisting of large, fluffy flakes (i.e., multiple flake packets). Wind was calm. Occasional flurries occurred before and after the period noted in the Duration block. The measured depth was 2.0 cm. I scraped a 14 cm by 44 cm patch into a pan and weighed the snow, obtaining 73 g. The meltwater equivalent was calculated from that.
1/9/2010 7:00 AM T T M M M Flurries in the morning; no measurable accumulation.
1/10/2010 7:00 AM T T T M M Fairly heavy flurries were observed periodically and what might have been a slight accumulation (a few millimeters) were observed at 0700. But by the time we got home from church, that accumulation was gone (due to wind and sublimation?).

I unplugged it shortly after noon once I noted that I was recording seepage past those seeds. I spilled a bit. The rainfall might have been a millimeter (0.04 in) of rain above this recorded value, give or take.
1/26/2010 7:00 AM T T M M M Intermittent snow flurries during the daytime hours ... at least. WX Station backup battery ran low at ~2100. We've had so much cloudy WX that the solar panel put out very little power and this sped the draining of the backup Li battery. Replaced ~1000 next morning. No pptn during this period.

1/30/2010 7:00 AM 1.65 2.1 0.21 1.5 0.16 Heavy snowfall from 1130 to 1530, sticking immediately. Measured 5.4 cm; estimated equivalent 5.4 mm of rain. Pptn continued as fine, frozen sleet, then rain. Temperatures rose slightly above freezing from ~1900 to ~0500 and the melt registered 25.4 mm in the tipping pan rain gauge. Pptn continued as extremely fine frozen sleet; mild white out with no individual visible flakes. At 0700 depth of accumulation was 4.2 cm. Scraped up a 18 cm by 18 cm patch and got 532 g of snow and ice; equiv. to 532 mL or 16.4 mm melted value for accumulation. Adding 25.4 mm reg. by gauge to 16.4 mm = 41.8 mm rain equivalent.

2/15/2010 7:00 AM 0.38 2.3 0.16 M M Enough, already! Heavy snow falling from about 0745 to about 1130 did not accumulate due to above freezing temperatures. Temperature climbed all evening then dropped like a rock, falling from +3.9 °C at 1100 to -5.9 °C at 0700. We had rain, turning to freezing rain, turning to snow, which stopped sometime before 0630. Tipping pan rain gauge registered 5.8 mm before freezing occurred. Snow depth measured 5.9 mm at 0800 this morning but there's about a millimeter or two of ice underneath that. Scraped and weighed a 14 cm by 25 cm patch of snow and got 138 g. The dental appointment that I deferred from last Wednesday due to ice and snow until today will have to be deferred once again.
2/16/2010 7:00 AM 0.07 1.7 0.06 3.0 0.18 Snowed heavily from ~0830 but did not accumulate on cleared section of snow board during the daytime (solar radiation).

Accumulation on cleared board started ~1700. Rain equivalents of snow calculated by weighing snow from scraped areas of known size (14 cm by 25 cm). New snow weighed 50 g; accumulated snow weighed 165 g; both ±1 g.

3/3/2010 7:00 AM 0.18 1.9 0.14 M M Snow started as a flurry then at about 0700 CST on Mar 02 it started falling heavily. Most of the snow fall was in quite large flakes, but the last couple of hours the flakes were smaller and wetter and then turned to light drizzling rain, ending at about 1600. During this entire time temperatures were above freezing. At about the time it turned to drizzling rain (1400 CST), I measured the accumulated depth (4.8 cm) and scraped a known area for weighing (139 g in a 12 cm by 28 cm area) to calculate meltwater equivalent. By nightfall, virtually all the snow had melted or washed away leaving only the odd patch on grassy areas in lee areas.

Frustrating! Obviously this is an election year -- all thundering bluster and no delivery on the promises. Someone could get a good study in orography from our weather.

8/11/2010 7:00 AM T M M M M Temperature dropped 3.6 °C in mid-afternoon then rose again. This was due to a small, passing shower. But it was so hot that as I took advantage of the "cool spell" to walk the dogs, all I felt was the fall of invisible drops of moisture on my skin that left no marks in the dust -- virga. That was at 1530.

A few wet spots on our decks mysteriously appeared, we saw dark clouds and "heat" lightning, and heard thunder. But nothing showed up in the rain gauge.

5/28/2010 1:32 PM Hail started falling at 1332, several minutes after first "trace" of rain was noted and just a moment after heavy rainfall started. Initial size was 2 mm. At 1337 it was up to 5 mm then became smaller. Hail nearly stopped at 1341 then resumed at 1344, ending at 1347. Any damage to leaves that was noted (blown down from trees) more likely due to intense rainfall (a rate of 276.1 mm/h was recorded at peak). I have no hail pads set up. No accumulation of hail. Station elevation is ~375 m ASL. 1/4" Pea Size Rice Rice Mixed|White Ice 2min no damage Intermittent True After rain After smaller hail 30-40
