Chicago, Illinois – Periods of strong storms are expected to sweep across Illinois Saturday, with damaging winds and localized hail likely, especially in central parts of the state by the afternoon.
According to the National Weather Service in Chicago, a weakening line of thunderstorms from Iowa and Minnesota is expected to reach Illinois early Saturday morning, bringing gusty winds to the northern half of the state. As the system redevelops, stronger storms could fire along and east of I-57 by midday, with wind gusts topping 60 mph and large hail possible in areas like Bloomington, Champaign, and Decatur.
The most likely scenario (60% chance) calls for storms to intensify by late Saturday afternoon, particularly over central Illinois. A less likely scenario would bring stronger winds to northern Illinois earlier in the day, while a lower-probability outcome could limit storm development altogether.
Drivers should avoid unnecessary travel during active storm periods, especially near construction zones or rural roadways. Residents are urged to charge devices, secure outdoor furniture, and monitor NOAA alerts for watches or warnings.
Storm chances remain elevated through Sunday, with the greatest impacts southwest of the Chicago metro. Showers may linger into Monday before clearing.
