11/11/2010 7:00 AM 0.27 2.3 M 2.0 M Snowing @ 0700 obs with small flurries...I was about 3 miles south of this site last night when snow started around 8-pm or so, with large wet flakes, not much accumulation on roads yet
11/12/2010 7:00 AM 0.09 M M 2.2 M Frosty morning and fog at 0700, but this site is low lying near the Poudre River, so the fog was distinctively limited to the low area near the river. I need to install a snowboard to measure new snowfall, will do that soon...
