Starry and windy by midnight (any new snow will be difficult to determine because of redistribution). Temperature rose from -6 at 10 pm to +2 at midnight with wind increase.
12/10/2009 7:00 AM 0.00 0.0 M 5.0 M Complete redistribution of snow from big winds - ranging from near bare to feet-deep drifts. I'm calling it 5" on the ground, assuming maybe an inch of sublimation since previous day (temps single digits at best). Wind chills to -20 last night.
