January 2010 began with bitter cold air early in the month with lows of around 30 to 35 below zero across northeast South Dakota and west central Minnesota.  The lowest temperatures for the month across central and north central South Dakota were in the mid 20s to around 30 below zero.  Despite a mid and late January warm up with highs in the 20s and 30s along with some lower 40s, the month managed to finish out below normal across the area. The monthly average temperatures were from 1 to 3 degrees below normal for all locations.

 With a couple significant weather systems early and late in the month, January’s precipitation ranged from slightly above to much above normal across the area.  Northeast South Dakota and west central Minnesota were the wettest with around an inch or more of precipitation for the month.  Much of this precipitation came in the form of rain and freezing rain.
