Chicago, IL – A steady December snow is blanketing northern Illinois this morning as winter weather returns in full force. Accumulations of 2 to 5 inches are expected across the metro, with wintry mix possible south of I-80, making for slick roads and challenging travel through early Sunday.
The National Weather Service in Chicago reports temperatures holding between 25°F and 32°F today, dipping into the teens overnight. Lake effect snow bands may redevelop early Sunday near the shoreline — particularly from Waukegan to Gary, Indiana — adding localized bursts of snow and reduced visibility for morning drivers.
Sunday’s highs near 30°F will feel colder under north winds and blowing snow. The chill deepens Monday as lows fall into the single digits, with lingering lake effect flurries north of I-88. Commuters should plan extra time and expect icy patches on bridges, ramps, and untreated side streets.
By Tuesday and Wednesday, another system approaches, bringing breezy winds and renewed snow chances. Highs rebound slightly into the mid-30s but gusts near 25 mph could cause brief whiteout conditions in open areas, especially west of the city.
