Chicago, Illinois – A broken line of thunderstorms is sweeping across northern Illinois early Tuesday, triggering gusty winds, lightning, and the risk of small hail through 8 a.m., especially along the I-88 and I-80 corridors.
According to the National Weather Service in Chicago, the strongest storms will push through counties from Rockford to Joliet before weakening as they move east. Affected areas include Kane, DeKalb, LaSalle, and Cook counties, with hazards like downpours reducing visibility and isolated lightning strikes. Drivers are urged to use caution during the morning commute, especially in shaded areas on the map where roadways may become slick.
Winds may gust high enough to down tree limbs or toss unsecured objects, particularly in rural and open areas. While hail is expected to remain small, it may still be enough to briefly impact visibility and vehicle safety. Storms are expected to diminish after mid-morning, but forecasters warn that additional rounds of thunderstorms are possible through the afternoon across the region.
Residents should remain weather-aware throughout the day and avoid outdoor activities during active storms.
