2/22/2015 9:00 AM 1.00 8.2 0.83 9.0 1.06 Snow began 0930 HRS and continued to 2025 HRS when it changed to sleet. Snow heavy at times w/ visibility down to 300' Sleet continued until 2100 HRS when it changed to freezing rain. Note: the sleet compressed the snowfall on the snowboard. The highest depth of new snowfall observed was 8.2" Liquid content of the snow and sleet was 0.83" The liquid content of the FZ was 0.17". This yielded a total event PCPN of 1.00" Note: Under the NWS COOP snow measuring guidance in effect from 1996 to 2013, I would have measured the snowfall and cleared the snowboard at 6 hour intervals. I did so for measurement comparison purposes during this snow. Under the 1996-2013 guidelines, my total snowfall would have been 9.4" The difference in measurements was due to significant compression of the snow during the afternoon hours.

2/27/2015 7:00 AM 0.06 0.6 0.06 6.0 1.33 SN continued after YSTD 0700 OBS through to 0950 HRS. The following are remarks from the Significant Weather Report filed by this station at 0950 HRS YSTD: "SN began approx 0430 HRS (radar based estimate) and ended 0950 HRS. 0.07" liq eqiv taken from SN that fell in 8" SRG. SWE thus calculated at 19:1 Core sample from snowboard using 4" rain gauge #1 yielded a liq eqiv of 0.06". Snow that fell into 4" rain gauge #2 yielded a liquid eqiv of 0.05" Highest wind gust recorded during the event was 5 mph from the NNE. Anemometer is 7' AGL. End of Report."
2/28/2015 7:00 AM 0.00 0.0 M 5.0 1.59 Low temperature this a.m. 8.0F @ 0632 Regarding the melted core value of the snow on the ground, I can't explain why the value has risen as the core was taken just a few feet from the snowboard. Yesterday's Max/Min temp was 28/17F With a high DP of 22F resulting in no little to no melting.
3/1/2015 7:00 AM 0.00 0.0 M 6.0 1.43 Snow on the ground remains on average 6" as little melting has occurred in the last 7 days. Core samples are difficult to obtain as the snow is hard and crusty. The melted value from the core sample should be considered an estimate.
3/2/2015 7:00 AM 0.45 0.4 M 7.0 1.93 See Significant Weather Reports filed during yesterday's SN and FZ. SN began 0840 HRS. FZ began in late morning hours after 0.4" of snowfall. Was unable to measure the liq. eqiv. of the snowfall. Efforts to get core samples using a plastic 4" rain gauge were unsatisfactory. Figures below are from use of an 8" diameter metal rain gauge which could more easily penetrate the almost concrete hard snow on the ground. Snow on the ground was exceptionally hard due to 8 consecutive days of dry, subfreezing air, and frozen earth.
3/3/2015 8:00 AM 0.00 0.0 M 6.0 1.62 Obtaining core samples of the liq eqiv of the snow on the ground is difficult. The snow is so hard that I can walk on the surface without breaking through. At 0800 air temp 26.2F DP 14.6F.
3/4/2015 7:00 AM 0.11 0.0 0.00 5.0 1.79 Light freezing rain began approx 1040 HRS. See Significant Weather Report. -FZ mixed with sleet @ 1140 HRS ending shortly thereafter. More freezing rain fell during the evening hours. FZ turned to rain overnight as temperatures rose. The rain has softened the rock hard snow cover.
3/5/2015 7:00 AM 0.87 0.2 0.02 4.0 1.69 RA during the day and overnight hours until approx. 0340 when sleet began. Sleet continued as the temperatures slowly dropped. At approx. 0610 the sleet changed over to snow. Moderate snow continues at 0650. Liq eqiv of new snowfall is estimated at 0.02" All other values are actual measurements.
3/6/2015 7:00 AM 0.71 7.1 0.71 7.0 2.45 See yesterday's repor. This is a continuation from the 3-5-2015 0700 obs. After yesterday's 0700 report, 7.1" of snowfell between 0700 and 1645 HRS (7.0") and 1915 and 2015 HRS (0.1") for total event snowfall of 7.3" (as predicted by the NWS for my CWA). My SWE ratio was 10:1. The 0.71" liq eqiv was derived from a core sample taken with a 4" diameter rain gauge from the snowboard. The NWS model output QPF for this event was a max of 1.45." I measured 1.58" total event PCPN from RA, IP, and SN. Pretty good forecasting. Low temp this a.m. 6.3F
3/7/2015 8:00 AM 0.00 0.0 0.00 5.5 1.78 Today is the 19th consecutive day with a snowpack. Core sample of snow on the ground difficult to obtain this morning because of a thick ice layer on the earth surface that was almost impenetrable. Some ice crystals remained on the ground despite two attempts to get a 100 percent sample. Estimated an approx. 5 percent underreporting (below true amount of snow on the ground). Low air temp this morning 2.5F @ 0502 HRS. Low DP -1.7F.
3/8/2015 7:00 AM 0.00 0.0 0.00 5.0 1.63 Had similar difficulties as yesterday's in getting this a.m.'s core sample (See yesterday's Observations Notes). Despite the second highest solar radiation reading (846 W/M2) since the beginning of the calendar year, and a max temperature of 45.1F, snowpack melting was light in the last 24 hours due to relatively dry air.
3/9/2015 7:00 AM 0.00 0.0 0.00 3.0 1.48 Yesterday's relatively high solar radiation reading (779 W/M2), increased wind speeds (average 24 hour wind speed 3.5 mph from a westerly direction), and temperatures (max 51.0F), resulted in significant melting of the snowpack.
