11/5/2017 6:03 AM 0.06 M M M M We got some snow during the night, but it had already melted by this morning: it lingers on the lawn and roof of my storage shed, is all, so there's no way to get a meaningful depth or water content reading on it. 36° this morning, so perhaps it was melting even as it fell during the night.

11/17/2017 6:16 AM 0.19 0.2 0.07 M M Snow began use before 06:00 with huge, heavy, wet flakes that covered my deck in a minute or so. The deck was already wet, so it seems to have been raining a bit but a short time before. Snow lasted only about 10 minutes, and has now turned into a mere drizzle.
11/18/2017 6:28 AM 0.31 1.2 M M M Snowfall reported must not be understood as representing all the snow that fell yesterday; rather, it represents the greatest accumulation before melting exceeded accumulation. In fact, it was above freezing even before the snow began to fall just after 06:00, and was melting even as it fell. It was a heavy, wet snow.

12/5/2017 6:45 AM 0.02 0.1 M M M I'm not sure the new snowfall amount is representative, due to the wind. Drifts are at least an inch deep in places, whereas much of the yard is bare. The reported depth was taken in a place that seemed least affected by the wind.

2/20/2018 6:10 AM 0.27 0.7 0.10 4.0 M It was a windy day again yesterday, and my snow board failed to capture as much snow as actually fell, as evidenced by the difference in measured water content. The drifting also results in large differences in on-the-ground depths, with sidewalks being nearly bare, and deep drifts elsewhere.

The snow stopped for several hours right around then, and didn't resume for several hours, so the depth reported is almost certainly less than the actual depth that fell. Snow is still falling very lightly at reporting time.
3/19/2018 6:00 AM 0.05 T 0.00 T 0.00 It snowed, lightly, most of the day yesterday, but the snow was melting as fast as it fell, so there was no accumulation.

I'm reporting Trace to reflect that snow did fall, but cannot be measured, and that some snow remains on the ground, but again, not an amount that can be measured.
