11/22/2016 11/27/2016 7:00 AM 6 0.55 T M The trace of snow on the ground arrived in the past few hours--it's lightly snowing right now. The gauge was emptied and measured upon our return yesterday evening, and 0.55 inches was in it at that time. By this morning it had only accumulated the additional trace of snow, which did not measurably increase the total multiday accumulation of precipitation. Presumably all or the majority of the 0.55 inches of precipitation arrived during the previous weather event that came and went in the days just before Thanksgiving Day.
12/25/2016 12/28/2016 8:00 AM 4 0.05 T M The snow on the ground when we left on the morning of the 24th appears to have mostly melted during that day--temperatures were in the 40s and what remains is now traces of clear ice in the shady areas. The snowboard had about .2 inches of newer snow on it this morning, probably from a snowfall a couple of days ago after the temperature dropped again. Lots of bare areas in the yard overall.

2/27/2017 3/02/2017 8:00 AM 4 0.09 5.0 M The precipitation fell as snow, but appears to have also experienced some melting since that time.

5/26/2017 5/31/2017 7:00 AM 6 0.06 0.0 M Rain accumulated in the gauge probably fell during the period from 5/26 through 5/27.
6/7/2017 6/11/2017 8:00 AM 5 0.00 0.0 M It is possible that trace amounts of precipitation fell early in the multiday period, but evaporated out of the gauge. Scattered showers did occur in the region during that time.

9/23/2017 9/24/2017 7:30 AM 2 0.29 0.0 M Precipitation during this period occurred during two distinct events. The first .13 inches fell within two hours after the previous reading on the morning of Sept. 22, and was recorded at noon on that day. The next opportunity to observe the gauge was at 3:00 PM on September 23, and no additional precipitation had occurred at that time. The remaining .16 inches fell during two short bursts of hard rain (mixed with a sleety hail)occurring at about 5 and then 7 AM this morning. At present, some traces of hail remain on the ground.
