Chicago, Illinois – A light coating of snow is expected across the Chicago area late Sunday into early Monday.
According to the National Weather Service Chicago, most of northern Illinois will start Sunday on the chilly side with mostly sunny skies before clouds thicken this evening. A fast-moving clipper system is forecast to bring a coating of snow of one-half inch or less to the region overnight.
Snow is expected to develop during the evening hours Sunday, potentially impacting travel along major corridors including Interstate 90, Interstate 94, Interstate 88, and Interstate 80. While snowfall amounts are expected to remain light, untreated roads, bridges, and ramps could become slick, particularly late Sunday night and early Monday morning.
Temperatures Sunday afternoon are forecast to reach the mid-20s, falling into the teens overnight, which may allow snow to accumulate efficiently on colder surfaces. Forecasters emphasized that even minor snowfall could cause localized travel issues during overnight and early-morning hours.
Looking ahead, the National Weather Service said the start of the week appears mostly quiet, with no widespread snow events expected across northern Illinois. However, another window for snow may develop Tuesday night, mainly confined to northwestern Indiana, where lake-effect snow could impact areas near Gary and along I-94.
High temperatures through midweek are forecast to remain in the 20s, with overnight lows dipping into the single digits and teens, reinforcing continued winter travel concerns.
Commuters, students, and young workers traveling overnight or early Monday are advised to slow down, allow extra time, and monitor road conditions before heading out.
The National Weather Service will continue to refine snowfall timing and amounts as the system moves through the region.
