3/11/2012 7:00 AM T 0.0 M 3.5 M Note that total snow is about half of what I've been reporting. This is because we've lost a lot of snow in the last couple days (due to wind and warm temps), so there is now about 50% of ground that's bare, while deeper areas still have ~7" snow cover. Reported total is thus the average.
3/12/2012 8:00 AM 0.03 T M 5.5 1.56 Too windy for new snow to accumulate on snow board, but there's a dusting on the ground so far. Total snow depth is depth of the core I took for today's SWE; overall, total snow depth varies b/w 0 and 7", with average of ~3.5", since about 50% of ground was bare (before the new dusting of the last few hours).
3/13/2012 8:00 AM 0.80 4.5 M 8.0 M wow, an intense 24 hrs of wx, with challenging measuring conditions! Snowed all day long yesterday, then rained hard last night. Lots of wind with both events. Max snow accumulation (measured during snow event, before it started melting) was 4.5" on average, but with wind drifting up to twice that depth in some areas. Total snow on ground was measured this morning, after last night's rain, which washed away a lot of snow that we received yesterday. In spite of that, ground is now fully snow-covered again (no bare spots).
