11/21/2019 7:00 AM 0.17 0.3 0.12 T M This rain/snow event was a tricky one to measure - started as freezing rain, changed to snow, then turned back to freezing rain/fog. At 5:45 pm, 0.2 in of snow was measured on the snow board (0.05 SWE), and 0.10 SWE in gauge. Thus, counting 0.05 rain + 0.05 snow at that time. I took my gauge inside after that, since it was supposed to be all snow overnight, so likely don't have an accurate measurement for freezing rain/fog from the overnight hours. However, an additional 0.1 in of snow/ice was measured on the board at time of measurement, with an additional 0.07 SWE.
11/22/2019 7:00 AM 0.33 4.4 0.33 4.0 0.29 Forgot to put out gauge, so all measurements are from snow board, which likely missed some of the freezing rain/fog during the daytime hours. Increments (time, depth, SWE): 5:45p, 0.4 (snow + ice), 0.04, 6:00a, 3.5, 0.26, 7:00a, 0.5, 0.03

2/24/2020 7:00 AM 0.07 1.1 0.07 M M Difficult (and inaccurate) measurement. It was warm enough that snow wasn't sticking well to exposed surfaces. I measured a snow board increment when there was 0.5", SWE was much too low (heavy, wet snow) and snow never accumulated on the board after that despite it snowing pretty hard. Reported measurement is from front steps where 1.1" had accumulated by the time the snow was done (but a lot had likely melted). Gauge measurement SWE was far too low to be considered accurate.

The gauge measurement came in at 0.24, but the funnel and inner cylinder had frozen over so snow wasn't fully captured
