A fast-moving clipper system will bring a quick shot of light snow to the Chicago area early tonight. Amounts are expected to be on the light side, generally an inch or less but with cold temperatures slick spots could develop on area roadways, especially lesser traveled and untreated ones.
The snow will end after midnight as skies clear and some sunshine will grace the city Tuesday morning. However, clouds will roll in during the afternoon setting the stage for a long-duration snow that will begin on New Year’s Eve and continue through much of New Year’s Day before winding down as a lake-snow event on Thursday, January 2. Snowfall totals could be substantial by the time the system moves out and latest model runs suggest many areas could get as much as 6-10 inches.
