Chicago, Illinois – A late-season winter storm could bring snow, strong winds, and hazardous travel across northern Illinois.
According to the National Weather Service Chicago, accumulating and blowing snow is expected to begin around 9 p.m. Sunday and continue through Monday afternoon, with the strongest winds developing Monday morning.
Forecasters say snowfall totals could reach up to 3 inches in some areas, though confidence in exact totals remains low. Locations outside the highest-risk zone may see lighter accumulations.
The greatest concern is travel conditions, particularly in areas northwest of Interstate 55, where the probability of hazardous winter travel is highest. Strong winds could gust between 45 and 50 mph, creating blowing snow and reducing visibility on open roads.
The NWS graphic highlights a corridor across northern Illinois—including communities near Rockford, DeKalb, Dixon, and Ottawa—where travel impacts are most likely during the storm’s peak Monday morning.
Local officials are also reminding residents that rapidly changing conditions can make roadways slick. The Frankfort Police Department encouraged drivers to slow down on wet or snowy roads, secure outdoor items ahead of strong winds, and stay alert for potential power outages during spring storms.
While snowfall amounts may vary by location, forecasters say wind-driven snow and reduced visibility could still create travel difficulties even where accumulations remain limited.
Residents are advised to monitor updated forecasts and road conditions, especially if commuting Monday morning.
