As Illinoisans return to the office after the holiday season, their Monday blues might be further magnified by lake-effect snow on the tail end of a major, disruptive snowstorm that slammed the central United States and by below-normal temperatures later in the week.

The Peoria area has "almost 100% chance" of snow on Sunday afternoon or early evening, with between 2-6 inches expected according to NWS meteorologist John Bumgardner, who said the heaviest snow will fall near Springfield and Decatur. The heaviest snow is expected to fall between 11 p.m. and 6 a.m.

A winter storm is moving through Central Illinois on Sunday, with snow falling in Peoria and Bloomington Sunday morning. Most of the southern half of Illinois is under a Winter Storm Warning.
