Cold February Wraps Up a Cold Winter

CHAMPAIGN, Ill. – Based on preliminary data in Illinois, the statewide average temperature for February 2010 was 25.1 degrees, 5.1 degrees below normal. Snowfall for February was above normal. Amounts ranged from 6 inches in southern Illinois to over 18 inches in the Quad Cities and Chicago areas.

The cold February, along with colder-than-normal temperatures in December and January, made this the 19th coldest winter on record. The 3-month average temperature was 25.3 degrees, 2.9 degrees below average. Winters in the late 1970s were still much colder with a virtual tie between the winter of 1977-1978 at 19.6 degrees and the winter of 1978-1979 at 19.9 degrees.

Winter snowfall totals (December—February) ranged from about 45 inches in northeast Illinois to just under 15 inches in southern Illinois. This was 1 to 3 inches above normal for southern Illinois to over 10 inches above normal in northern and western Illinois. Wintertime precipitation, both rainfall and the water content of snow, measured 7.04 inches and was 0.35 inches above normal.

The latest National Weather Service outlook for March calls for an increased chance of below-normal temperatures in the southern two-thirds of Illinois. It also calls for an increased chance of drier-than-normal conditions for the month. See the Climate Prediction Center page.
