November 2015 was a very warm month across central and northeast South Dakota as well as west central Minnesota.  Monthly average temperatures ranged from 3 to almost 9 degrees above normal across the region.  It was interesting that Aberdeen, Sisseton, Watertown and Wheaton, Minnesota were nearly as warm or warmer than Kennebec and Pierre in central South Dakota.  This does not happen very often for anytime of the year.  As a result, all locations in northeast South Dakota and west central Minnesota had one of their top ten warmest Novembers of all-time.  Watertown tied for the fourth warmest while Sisseton had their ninth warmest November on record.  Wheaton had its sixth warmest November while Aberdeen had its tenth warmest November on record.  Some record highs also occurred at Aberdeen and Mobridge on November 14th.  The warmer temperatures were due in part to the lack of snow cover across the region along with El Nino.

The monthly precipitation across the region was generally from a quarter of an inch to three quarters of an inch above normal. Most of the precipitation was rainfall, which, for our region, would normally be snowfall. Timber Lake was the only location with below normal precipitation.  An intense surface low pressure area brought good coverage of rainfall on the 18th and 19th along with very strong northwest winds.  Many locations received from a half inch to over an inch of rainfall with high wind gusts from 50 to nearly 80 mph.  The snowfall mainly came at the end of November into the first of December as a large upper level pressure system affected the region.  This snowstorm brought anywhere from 3 to 10 inches of snow across the region.
