1/21/2017 1/23/2017 8:00 AM 3 0.28 M M a few drops of rain at the time of measurement on 1/23 as the first edges of today's nor'easter begin to reach us. Most of the 0.28" reported is from the afternoon/evening of 1/20, a very little fell on 1/22
2/9/2017 2/10/2017 8:00 AM 2 0.40 4.2 M Snow stopped on 2/9/17 at about 10:00 am, I took my measurement of depth around 11:00 am, therefore I'm reporting it as a 2-day measurement to avoid showing 0.00" for 2/10/17 8:00 am when most others in the region would show precip on both days.
