12/12/2016 1/01/2017 9:00 AM 21 2.03 M M Away for three weeks. Deep, dry snowfall while we were gone. Probably over a foot of snow. From reports, most of that probably fell on 12/31. Rain + snow gathered in gauge melted down to 2.03" of ppt. Weather very cold, but dry and windy. Between evaporation and faulty snow gathering, 2.03" is probably less than actual ppt.
