12/9/2009 7:00 AM 0.05 M M 3.0 M Clouds moved in early this AM, temperature warmed to around -7 and it snowed very lightly between 6:30 and 7Am. We got 0.1" in that time. Unable to accurately report new snow depth because wind blew measurement board clean yesterday before I could measure.
12/10/2009 7:00 AM T 0.3 M 3.5 0.39 Had wind driven snowfall from about 6:30PM to 9PM last night. Do not believe rain gauge or measurement board caught all of the snow, so included a core measurement of average depth of new and old snow on the ground. Hope that helps.

Snow that fell during dark hours was blown off all smooth surfaces so accurate measurement not possible. Would estimate in the 0.1 to 0.2 range--not much. Gauge may not have caught total amount of snow.

1/7/2010 7:00 AM 0.01 0.1 M 5.9 1.03 Warm temps and wind during daylight hours caused snowpack to settle and light snow flurries to melt as they fell. Colder temps and higher winds after sunset as well as a little more snow caused drifting. Snow in gauge and on board probably measured low. Determined snow depth on ground by several measurements taken over a wider area than usual.

4/4/2010 5:45 AM 0.12 1.3 0.13 1.5 M I know that wind blew the snow off the snow board at times and probably caused the rain gauge to miss some too. Both measurements are probably a little bit low. Still snowing lightly at time of report.
