12/13/2015 7:00 AM 0.19 2.7 M M M Had 2.7" of snow on snow board, but 3.8" on picnic table a few feet away. Yesterday the snow appeared to be approx. 5" on picnic table. Must have been considerable settlement during night?
12/15/2015 7:00 AM 0.20 3.1 M 4.4 M Still snowing lightly at time of measurement (7:00 AM)
12/23/2015 7:00 AM 0.05 0.3 M M M 0.05" water appears to be too much for only .3" snow. But, I noticed my driveway was wet yesterday ( Tuesday) afternoon, so suspect there was some slight amount of rain. The snow came sometime during the night.
12/24/2015 7:00 AM 0.04 0.7 M M M
12/26/2015 7:00 AM 0.12 2.1 M M M Note: wind gusts blew snow around significantly during evening and night. Still gusty this AM. Snow blown off and on my snow board, so 2.1" on board is probably not accurate! Some gusts 15 to 20 mph.

3/18/2016 7:00 AM 0.41 4.7 M M M Note: morning paper on driveway was completely buried with snow. The paper usually arrives between 4;30 and 5:00 AM, so the most of this snowfall must have come after 4:30 or 5:00 this morning!
3/19/2016 7:00 AM T 0.2 M M M
3/23/2016 7:00 AM 0.86 4.6 M M M Must have had rain prior to snowfall, because I don't think 4.6" melted snow could yield 0.86" water. Snow began sometime AFTER 3:40 AMbecause I was up then and looked out and there was no snow on ground. When I got up at 5:30 AM, we had a bunch!
