After a couple warmer than normal months, February 2015 had below to much below normal temperatures across central and northeast South Dakota as well as west central Minnesota.  Average monthly temperatures ranged from 2 to as much as 9 degrees below normal.  There was quite a range in temperatures across the region for February as mild Pacific air and bitter Arctic air battled it out, especially across central South Dakota.  The differences between the high and low temperatures were anywhere from 76 degrees at Mobridge to 87 degrees at Kennebec.  In fact, all four locations in central South Dakota set record high temperatures on February 7th.

The abnormally dry conditions continued across the region mainly east of the Missouri river throughout February.  Moderate drought conditions continued to be felt across a large part of northeast South Dakota. February precipitation was below normal for all locations except for Mobridge where it was slightly above normal for the month.
