12/12/2010 7:00 AM 0.27 0.4 0.03 M M Yesterday it rained, then sleeted, then snowed. There is a layer of ice under the snow. This morning the wind is roaring and blowing out of the north, northeast, and sometimes there is a gust from the northwest. The small amount of snow that fell is being blown around. It may be snowing now, but it's difficult to tell. The snowflakes that I saw looked like small slivers of ice.
12/13/2010 6:00 AM 0.04 0.6 0.04 M M Due to yesterday's strong winds all precipitation measurement information should be considered inaccurate. I can confirm it did snow yesterday. The wind created whiteout conditions for many hours. All snow board measurement locations were blown free of all snow that fell. Measurement information for this reading came from the cylinder. Since there was a layer of ice covering the ground prior to the snow and wind, the snow that did fall was easily blown by the wind since it wasn't able to settle into place.

Probably more like 1/32" thick. The glazing could be found on the east and southeast sides of vertical surfaces. 3 locations were averaged for snow depth. Those same 3 locations plus the outer tube were used for the melted value average.

12/30/2010 7:00 AM 0.04 M M M M Foggy and a very damp outside. There is a mist in the air. The snow and ice is melting due to the above freezing conditions. Dripping water can be heard outside everywhere. First time we've had a significant warm up since the beginning of December. There will be a lot of melted run off water. I'm not certain whether the .04" of precipitation in the gauge was from the fog or if it was actual precipitation. The ground is still 100% snow covered except where it was shoveled or plowed.
12/31/2010 7:00 AM 0.14 M M M M Raining and foggy at the time of observation. Snow is melting everywhere due to the above freezing temperature and rain. Some roofs still have snow on them while others have none. It's hard to say exactly how much of the snow has melted. Underneath trees or shrubs it appears to be for the most part all gone. In open areas some locations still have snow while others have lost a lot. Just a rough guess, but overall I'd say 40 to 50% of the snow cover has melted. The ground is frozen so the water is puddling on top. The frost is only about 2 inches into the top of the soil. Between 6:30 and 7AM this morning I observed some lightning and thunder.
1/1/2011 7:00 AM 0.16 M M M M The rain stopped yesterday about mid-morning. The fog cleared out after the wind picked up last night. The warmer temperatures have turned much colder. I'd estimate about 1 to 2% of the natural untouched snow cover remains. For the most part, the blanket of snow that covered everything since the beginning of December 2010 is completely gone. Many manmade piles of plowed or shoveled snow exist, but the volume is much less than what it once was.

1/18/2011 7:00 AM 0.32 1.5 M M M One of those "difficult to measure precipitation" type of winter storms. It started out snowing yesterday morning. The wind was blowing so some measurement locations had drifting while others had nothing. Then the snow changed to sleet and then to rain in the afternoon. Later about 9PM it began to snow again. There was some type of precipitation in the air all day yesterday. Quantifying the numbers for this is a problem. The accuracy of the numbers for today should be questioned. Several measurements were taken, but there was a lot of variation. I was unable to determine the amount of water found in the newly fallen snow since rain mixed in with it. The snow accumulation depth measurement is probably invalid due to compacted snow from the rain.

2/2/2011 8:00 AM 1.90 14.6 1.90 M M A historic winter storm snowfall and I honestly have no idea what to report. The snow that blew and drifted all over made measuring the snow extremely difficult. One place had snow and another had nothing. Conditions for snow measurement are terrible. The strong winds made snow measuring practically impossible. Due to the wind 2 of the 3 snowboard locations were completely windswept. The location I took a measurement from more than likely was impacted by drifting snow making the measurement very questionable. Drifts within 50 feet of the snow boards were 0 inches up to 34 1/2 inches tall. The wind is still blowing the snow. Lightning was observed about 9:30 PM last evening. I have yet to see a vehicle other than a snow plow travel past my place. It took a snow plow with a side wing about 8 passes to completely clear the road.
