Chicago, IL – A mix of snow and rain is expected to impact Illinois and parts of northwest Indiana starting late Tuesday night, bringing slippery road conditions and potential travel delays through Wednesday. The National Weather Service forecasts a 20% chance of a narrow snow band forming overnight, with minor accumulations possible on untreated surfaces.
According to the National Weather Service, this weather event could create slick spots on roads, especially south of I-80 and along I-55 during Wednesday afternoon. Temperatures are expected to climb above freezing by midday, reducing snow accumulation risks, but drivers should exercise caution during the morning commute.
Wednesday evening could see periods of rain mixed with snow, particularly in areas south of Pontiac, Illinois, to Rensselaer, Indiana. Temperatures are expected to drop into the 20s overnight, heightening the risk of icy patches.
Looking ahead, Thanksgiving Day will bring lake effect rain and snow showers to northwest Indiana, with colder air moving into the region by Friday. Highs on Thanksgiving will remain in the mid-30s, followed by blustery and frigid conditions Friday and Saturday, with lows dipping into the teens.
