10/25/2012 7:00 AM 0.21 0.5 0.05 M M Started out as rain yesterday afternoon and switched over to snow in the evening (~6PM) Because surfaces were warm and the temperature near freezing, it was difficult to measure exactly what the snow contribution was and what was rain. The best estimate is 0.16 rain (already melted in the gauge) and 0.05 liquid water equivalent (from the snow in the funnel). There was 0.5" snow on a board and that looked reasonable based on depth of snow in the funnel.
10/26/2012 7:00 AM 0.20 3.5 0.20 3.5 0.20 Both the melted gauge content and the core came to 0.20" water. 3.5" new snow on most surfaces. The snow from yesterday morning melted by noon yesterday.

12/19/2012 7:00 AM 0.26 4.0 0.26 4.0 M It started snowing ~4:00 in the afternoon - big clumps of snowflakes coming down. It slowed down ~6 PM and then was snowing more heavily around 8:30 PM. In between 6 and 8, it seemed like some of the snow either settled or melted: there was ~1.5" on the front railing and then there was only 0.5". The snow also came with wind. The gauge looked drifted and the melted equivalent was 0.21". In the yard, I did a core in a spot that had 4" of snow. (There were other spots with more snow and less snow) The water equivalent was 0.26 and this is what is reported.
12/20/2012 7:00 AM 0.07 1.6 0.10 4.0 M Snow in the morning and clearing by afternoon. There was quite a northerly wind too. Both the gauge and the board where I measured this morning looked affected by snow, so I averaged the 2 measurements this time. The gauge had 0.04" and the core had 0.10". My best estimate of new snow is 1.6"

1/12/2013 7:00 AM 0.01 0.3 M 1.5 M Snow mostly yesterday in the morning. We still have snow in the yard, although I haven't been measuring the depth. Our yard is somewhat shaded and has more snow than surrounding fields. There is no snow under the big spruce trees. The east yard has about 3", the southwest yard has about 0.5, the northwest part has about 1.5", and the back yard with the least sun has ~4.0 " so an average of 1.5"

The east and north sides still have snow (1-3"), although the south part of the yard is showing grass. The shading affect of the trees is significant. Without wind, the snow affects how cold it is around the house when not in direct sun. So it still feels like winter even with daytime temperatures reaching the 60s.
1/23/2013 7:00 AM 0.00 0.0 M M M Last evening, I did a core of the 2.1" snow in the shade and it had 0.59" water! So, I'm not so sure that reporting a trace of snow is representative either.
1/24/2013 7:00 AM 0.00 0.0 M T M Snow melting quite a bit more yesterday with the relatively warmer overnight temperatures (low around freezing) on the 22nd and the warm daytime temperatures - up to 60F. Where I did the core the other night, there is only 1" today!
1/25/2013 7:00 AM 0.00 0.0 M T M Truly a trace of snow left. Warm temperatures and lots of melting.

1/29/2013 7:00 AM 0.10 1.5 0.10 1.5 M Snow overnight - from looking at Christman Field data, probably between 1 PM and 1 AM. The gauge gave 0.09" and the core gave 0.10". Since the core looked more uniform, I used that value.

We picked up a good inch during this time. This morning, the temperature was in the teens and there was fog. It made for pretty hoar frost on snow and other surfaces.

But The snow also seemed wetter today and there were times where it was snowing heavily. Total snow is an average of 2 measurement of 6.5 and 5.5

3/12/2013 7:00 AM 0.15 2.5 0.13 2.5 M Started snowing ~7 PM last evening and was accumulating on grass, trees and bushes, and colder (shaded) ground spots, but was melting on warm concrete surfaces. This morning, more concrete ground surface was covered, but not completely. Not windy - snow nicely highlighting branches and fences. My husband took my smooth piece of board (my snow board substitute) and replaced it with an old pice of board with a rough surface. The melted SWE from that core was a little less than what was in the gauge and I suspect the main difference is due to melting. Gauge=0.15", core=0.13"

4/16/2013 7:00 AM 0.90 11.1 0.93 13.5 M I measured snow yesterday at 5:20 PM and again this morning at 7 AM. New snow from yesterday evening 4.8" gauge liquid equivalent was 0.51 and the core was 0.59 (so I averaged them to get 0.55); This morning there was 6.3" additional new snow with the gauge liquid of 0.35 and the core of 0.34. (total new snowfall = 4.8 + 6.3=11.1; liquid= 0.55+0.35=0.90) There was graupel at 7 AM. The outside of the gauge had a very thin layer of ice and the top layer of the snow was a little crusty as well (freezing rain). Yeah for the moisture.
4/17/2013 7:00 AM 0.50 3.0 0.47 11.0 M Brownish snow this morning - and I checked satellite imagery and there looks like there was a major dust storm out of the 4 corners area yesterday that came right over us. Crusty top- a freezing layer about 0.15" thick. Crazy April weather!
4/18/2013 7:00 AM 0.34 5.0 0.42 14.0 M All snow fell before 5 PM. There were blizzard conditions between ~9:30 and 11:30AM (although I wasn't looking out the window the whole time). That said, there was wind. I measured at 5 PM and at that point, the gauge was mostly slush. Where I had the board to measure new snow may provide an overestimate (0.42") due to a little drifting, and the gauge provided an underestimate (0.26), so I'm putting in an average above (0.34). Even though I fully appreciate the moisture, I'm glad we have some sunshine today.
4/19/2013 7:00 AM 0.00 0.0 M 8.0 M My estimate of total snow still on the ground is an average of 5 measurements around the yard.
4/20/2013 7:00 AM 0.00 0.0 M M M Sorry I didn't have time to measure remaining snow, but quite a bit melted from yesterday. Probably 3-4" remaining in our yard and it made it feel cold at the end of the day.
4/21/2013 7:00 AM T 0.0 M M M Trace of rain in the late afternoon. not enough to fully wet ground though. I didn't get out to measure how much snow was left, but I estimate ~ 1 inch. Some places still had 3" ( including the north side of the garage roof), and some places had none to 0.5.
4/22/2013 7:00 AM 0.01 0.0 M 0.0 M The pavement was wet at 5:30 AM. My husband said the ground was also wet at 2 AM. I don't have my funnel in yet in anticipation of more snow today/tonight. Essentially all the snow from last week is melted. The only remaining snow is from where it was shoveled into piles.
4/23/2013 7:00 AM 0.56 5.5 0.57 5.5 M It started snowing in the morning, accumulated ~0.5" on the grass, then melted. It kept snowing lightly, then started in earnest again at around 2PM. It was windy at times as well. I was almost surprised that the gauge liquid was so close to the core, but the gauge likely captured more of the early snow whereas it might have melted off the board for the core. Or maybe I was dreaming when my pants seemed to capture snow all down my legs (from blowing snow) as I was walking to the car and clearing the snow off it.
4/24/2013 7:00 AM T 0.0 M 1.5 M Lingering snow yesterday in the morning that did not measure up. Snow still on tree branches.

5/1/2013 7:00 AM 1.74 8.5 1.24 M M I didn't go out and measure the rain last night before it changed to snow, but we had good rain before the snow started (we had water accumulating in spots that indicate heavy rain). When I went to pull down the gauge, it was very heavily drifted to one side and that drifted part was not captured in the measurement. The sample was very shushy with ~3" snow sticking about that. The gauge catch melted to 1.43". My core was a sample of 8.5" snow. It melted to 1.24" liquid. As a quick guestimate of the amount of rain, I looked at what fel up to 10 PM at both Christman field (which is close to where I live) (0.58"), Fort Collins (0.5") and comments from other CoCoRahs observers on the north and west side of town. I don't think it unreasonable that I had 0.5" of rain. Which is 0.3" more than the total of what my gauge caught. So I am reporting 0.5 + 1.24 = 1.74"
5/2/2013 7:00 AM 0.34 4.0 0.34 10.5 M Wet snow, warm ground. There was steam coming off the roads yesterday mid-day when it was snowing -cool! During the day, snow didn't accumulate on my car and it was warmer inside than I expected. Icicycles hanging off tree branches with snow on the top of the branch. The gauge was melted by the time I saw it. It had 0.27 liquid. The core had 4" snow which melted to 0.34, so I used that.

Another 0.05 by 7 AM. Mostly steady rain here with an occasional break in rain and an occasional heavier rain period. The squirrel looked pretty soggy this morning. I think the rain is keeping the raccoons away from the ripening grapes :) but with so much rain, the grapes might start bursting. We are very thankful that we and not being negatively impacted by the rain.
