11/11/2012 7:15 AM 0.03 1.0 M 4.0 0.28 The amount of water equivalent in gage should be sufficient for the new snow that fell yesterday. There may have been some settling of the total snow depth as it increased by only a half inch from what I measured yesterday.
11/12/2012 7:40 AM 0.00 0.0 M 2.0 0.18 No new snow is forecast for the area and temperatures are anticipated to reach highs above the freezing point. Unless new snow occurs between now and tomorrow's observation, this will be the last water equivalent reading for this past storm as I anticipate the total snow depth to fall below two inches today.

11/26/2012 7:30 AM 0.30 M M 3.5 0.35 For much of the time snow had melted as it fell yesterday until evening. Thus, I could not get an accurate measurement of what new snow fell. Moreover, melting occurred from the snow that fell Saturday night. Therefore, the total snow depth would have been affected. I have not included new snowfall for reasons stated above, but I am including the total snow depth and water equivalent as I measured it today.
11/27/2012 7:20 AM 0.00 0.0 M 3.0 M No additional snow fell from the time of yesterday's observation until now. As I understand it, snow depth core samples are done on Mondays when the snow depth is two inches or more. Core samples are taken when new snow has fallen on top of the older snow depth. No new snow has fallen since yesterday's measurements.

4/16/2013 7:20 AM 0.02 T M T M Very light snow in progress at time of observation. Snow that fell yesterday melted so that only a trace remained on the ground at time of observation. Thus, the water equivalent of what fell yesterday into early this morning will have to suffice.
4/17/2013 7:30 AM 0.02 0.2 M M M There was melting of snow during yesterday and what snow had fallen the previous day, only a trace remained. Thus the total snow and ice on the ground is the same as the snow that did accumulate yesterday into last night.
4/18/2013 7:25 AM 0.04 0.4 M M M A heavy snow shower affected the site from about 4:40 PM til about 5 PM. I took a quick measurement after the shower abated and we received 0.5 inches from it. The snow on the measuring table settled a bit, thus the reading this morning differs by a tenth. Snow that fell the previous day had melted to a trace. The water equivalent in the gage seems reasonable since the snow that fell yesterday was wet.
4/19/2013 7:05 AM 0.00 0.0 M M M All snow that fell during Wednesday had melted yesterday. No snow remained on the ground at observation time today.

4/22/2013 7:25 AM 0.15 2.6 0.17 2.5 0.17 I cannot guarantee the accuracy of the snow accumulation. Some snow fell shortly after my observation yesterday. I estimate about a half inch was on the roof of my car when I cleaned it up in preparation to go to church. All of it had melted by the time worship services were over. This amount that I measured fell during late afternoon and is continuing to fall at observation time.
4/23/2013 7:25 AM 0.01 0.1 M T M Light snow fell intermittently during the day but it melted quickly. Based on the water equivalent in the gage, and the previous observation of snow amount and its water equivalent, I am estimating that a tenth of an inch of new snow fell yesterday. Only a trace of snowfall remains for today's observation.

9/7/2013 9:00 PM The hail covered the deck and yard to about a quarter of an inch deep. It looked like snow. Looking at aftermath this morning, bark mulch from our southern neighbor's yard was blown into our front yard across our driveway. Some of that mulch was blown into our front porch. Some hail yet remains under our aspen trees in front of our house. We also had scoria blown into our porch and driveway. 1/2" Grape 3/8" 1/4" Pea Size Mixed|White Ice 15 shredded leaves Continuous True Same time as rain Same time as smaller hail 50-60
