I do this thing that measures the length of a winter season. The criteria is simple and can be found at the link. Each winter is unique. Long, short, divided. 2014-15 is becoming special in it's own way. Earliest divide since 1994-95? If the MaxT is above 32F 12/26 and the snow depth at obs on 12/27 is < 1 inch, the 2014-15 winter will have come to a halt. 1994-95 and current 2014-15 WSD charts attached below.
I have WSD data back through 1990 for Oshkosh/OSNW3. For the summaries please click here. If there are any questions, comments, or suggestions on the material presented please let me know. Thanks for reading!
