Observation Date Observation Time Precipitation Snowfall Snowfall SWE Snow Depth Snow SWE Notes
10/26/2009 7:00 AM 0.43 4.1 M 3.2 M Snow was likely greater as was melting from below.
10/28/2009 7:00 AM 0.99 5.2 M 5.0 M This storm started with light rain at 555pm. The rain became moderate as temperatures dropped from about 49F to freezing by about 830pm when snow began (very wet of course). The snowboard missed the rain so I used the gauge for liquid. The gauge was ringed with snow about 2" high by morning so I pushed straight down to take the measurement.
10/29/2009 7:00 AM 0.77 15.1 0.75 M M The snow transitioned as the temperature dropped into the high twenties to large aggregates at a high rate. In the morning, having dropped to 24F, the flakes became small, almost grains (not accumulating much, more dense). I did an interim observation at 430pm yesterday with 8.8" and 0.45" liquid (so 6.3" additional 430pm-7am).
10/30/2009 7:00 AM 0.26 2.8 M M M Estimated as high winds overnight cleaned off snowboard and gauge catch was compromised. Fortunately I made a depth observation on the snowboard before the wind started and after the snow ended at 930pm. Liquid is estimated based on hydrometeor type all day during snow.

Core taken over grass and 0.1" liquid added to account for snowmelt and rain that felt before snow. Snow taken in two measurements 7.8 10pm day before and 6.4" 8am day of report. Core used as gauge due to poor gauge capture (bridging of wet snow).
