Chicago, Illinois – Drivers across northern Illinois should expect hazardous travel through 7 p.m. Wednesday as scattered thunderstorms bring heavy downpours and isolated lightning strikes to the region.
According to the National Weather Service in Chicago, the greatest threat spans parts of the state shaded in yellow on the alert map—including DeKalb, Joliet, Ottawa, and Kankakee—where locally intense rainfall may lead to minor flooding. There’s also a chance for funnel clouds to form, although severe storm development remains limited.
Areas south and west of Chicago, including Pontiac, Dixon, and Paxton, could see brief but intense showers moving east at 5–10 mph and northeast at 40–45 mph. While not widespread, isolated cloud-to-ground lightning poses a risk for those outdoors or traveling.
Officials urge caution on wet roads and remind drivers: never cross flooded intersections. Residents should move indoors if thunder is heard or lightning is visible.
The storm threat is expected to diminish by early evening, but new advisories may be issued if cells redevelop.
