1/4/2018 8:30 AM 0.12 0.3 M 0.5 M Light snow ongoing. 0.12" SWE gauge-caught and is surprisingly high. Suspect poor snow growth/ratios are partially to blame. Might also have been snow blowing off board leading to a slightly low new snow depth, but don't believe 0.3" was unrealistically low.
1/5/2018 8:00 AM 0.51 4.1 M 4.5 M 0.51" was gauge-caught SWE. Measured an additional 3.5" on board (0.52" core SWE from that) at 4:30 PM as snow was ending, yielding 0.3"+3.5"=3.8" event total. Snow on ground at the time was 4.5"-5.0", so 3.8" event total from board likely a modest underestimate due to wind blowing snow off the board. Therefore, I've adjusted today's "new snow" to 4.2" to yield a conservative 4.5" event total snowfall. Event total SWE (all gauge-caught) of 0.13"+0.51"=0.64" is surprisingly high for just around 4" of snow! Presume that poor snow growth at beginning, and strong winds compressing snow led to poor ratios.

Adding in yesterday's 0.3" (which melted some before afternoon snow blitz) yields 11.1" event total, and 2.58" event total precip. After a few (~2-3) inches, had a 1-2 hr period of sleet starting in the 1 PM hour. Changed back to snow around 3 PM and received bulk of remainder (~8") during following 2-3 hrs.Took two cores off snow board: 2.23" and 2.17". Will use 2.23" as precip, as snow built up on gauge post, blocking snow from entering. Possible some some early precip on the morning of 3/7 melted off board and wasn't accounted for, but don't think this was substantial.
