Chicago, Illinois – Thunderstorms could rattle northern Illinois Monday evening, with the potential for damaging winds and heavy rainfall disrupting commutes and outdoor plans across the Chicago area.
According to the National Weather Service in Chicago, scattered to numerous thunderstorms are likely Monday afternoon through the early evening, with a Level 1 of 5 risk for severe weather. Forecasters warn that any storm could produce lightning and torrential rain, and a few could generate isolated damaging wind gusts.
High humidity and daytime temperatures nearing 89°F will fuel unstable conditions Monday. Evening storms could impact major highways like I-55 and I-94, especially during rush hour.
