December and March are weighted lowest, as one is basically Fall and the other Spring in the lowlands. January was pretty epic for here with over 19" of snow and generally cold, with snow otg for many days. February was pretty pathetic with very little snow. The late Jan snow was still otg with cold temps for the first couple days of the month- that was the highlight.
In the end, snowfall for my yard was slightly above average, and the best pattern set up during the ideal month (combo of low sun angle and cold/snow climo) and delivered with 3 snowstorms and one snow/sleet to rain deal. It was disappointing that literally nothing else transpired after that great start, but so it goes with Ninas in the MA in a warming climate.
Overall grade: B-
