12/31/2010 7:00 AM 0.28 7.0 M 5.5 M Depth very difficult to determine. Ground cover ranges from 0.1 up to 16 inches in drifts. Took an average of the depths to come up with 5.5. Used a 25 to 1 snow to liquid ratio to come up with the 7 inches, based on the fact that most of the snowfell after 430pm when the snow flake growth was much more efficient than earlier in the day when the flakes were much smaller. Also, much less snow fell here prior to 430 pm compared to in Cheyenne...less than an inch prior to 430pm. Winds at observation were 2 min avg 15 mph with peak gust at 28 mph at 643 AM MST this morning.
