Mini rant:
Looks can be deceiving but, the smaller storms like this one in the earlier part of the record are almost always harder to re-analyze, esp when so many voluntary observers don't seem to understand the difference between a dusting-0.5" of snow and a trace. If a trace of snow is "on the ground" that's not a trace of snow (ugh).

Just as an example of what I go through every time to make this end map, here are the obs + notes I took on this particular storm (do this for every storm). Some of them are comments from the COOP observer, others are mine, mainly reasoning for changes I made to each individual COOP ob.
