March certainly is volatile but people always underestimate how often we see measurable snow in the month of the Mars God. The last two years were a bit of an anomaly in that I recorded absolutely nothing in March; however, four of the five years prior to that I recorded substantial snow in March, with three of the four totaling over a foot. Heck, two of my last six Aprils have seen over an inch of snow. Harrisburg has only seen four March's in its history that totaled zero snow (with about another 14 with only Trace) but over 50 where it recorded at least six inches.
