10/6/2010 7:00 AM T M M M M it tried very hard to rain at about 7 pm last night. Clouds rolled in (actually they are still around) and it sprinkled lightly for a couple of minutes.
10/7/2010 7:00 AM 0.27 M M M M Biggest rain since Aug 23 (matches that one). Rain came in two separate storms, one at 5 pm with pea sized hail and one around midnight without hail. The midnight storm was a real thunder and lightening display. I don't know which one dumped the most rain. Bright sunny morning, surprisingly it did NOT freeze in the early am.

5/12/2011 7:30 AM 0.78 4.0 0.78 5.0 M Very hard to accurately measure the snowfall amount as there is a good half inch of ice-slush at the bottom of the snowboard. I guessed 4" as the best approximation. Snowing lightly at time of measurement today, overcast. 5" is my best approximation for total snowfall, since south facing slopes have less..almost bare ground.

4/14/2011 4/19/2011 8:00 AM 6 0.71 T 0.71 Had funnel on guage but not smaller rain funnel, hoping this accurate for the week I was gone. I'm sure most of the precipiation was snow, but can't be sure.
4/22/2011 4/25/2011 8:00 AM 4 0.39 3.0 0.39 Snowed last night but there was snow mixed with rain over the weekend.
