Chicago, Illinois – Scattered thunderstorms are set to move across northern Illinois today, bringing heavy downpours and gusty winds to Chicago and surrounding cities through early evening.
According to the National Weather Service in Chicago, storms will first develop in far northern Illinois—including Rockford—between 11 a.m. and 3 p.m., then track southeast through Aurora, Joliet, and Gary from 2 p.m. to 5 p.m. By late afternoon, the threat shifts toward Ottawa, Watseka, and the southern suburbs, with storms likely from 4 p.m. to 7 p.m. Rainfall rates could reach 1–2 inches per hour, leading to a risk of localized flooding.
Gusty winds over 50 mph and frequent lightning are possible, especially in the hardest-hit areas south of I-80. Travel could become hazardous on major roadways like I-55 and I-57 during peak storm hours. Residents should move indoors if they hear thunder and monitor multiple sources for weather alerts.
The main threats are flash flooding, brief power outages, and strong winds. Keep devices charged and avoid unnecessary travel through the evening. Thunderstorm risks will gradually end from northwest to southeast by nightfall, but additional watches or warnings may be issued if storms redevelop.
