Here is an interesting link from Millersville. Just change the date portion of URL for the decade. Quick scan on the 70's, 80's and 2000's shows 90-100 snowfalls each decade (taking out trace records). The 90's certainly stands out as having less than 90 snowfalls but the highest total snowfall of any of these decades.
