2014-15 First Day of Winter
The winter of 2014-15 has begun. Winter is officially here, in my backyard. Let me review the the conditions that constitute a winter season. The definition of a Winter Season Duration (WSD) is as follows, and in the case of OSNW3, six(6), is used for "several" consecutive days.
First Day of Winter represents a daily max temp equal or below 32°F and a snow depth of 1" or greater for several consecutive days.
Last Day of Winter represents a daily max temp equal or above 32°F and a snow depth less than 1" for several consecutive days.

The winter of 2014-15 began on Nov 21, 2014. Which is the earliest by 2+ weeks since 2006. Below is a graphical representation through Dec 9, 2014.
Just an FYI. The winter of 2013-14 lasted 109 days, so did the winter of 2012-13.
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!
