Tinley Park, Illinois – Residents east and southeast of the I-55 corridor face a Level 3 out of 5 severe weather threat today, with scattered showers and storms possible throughout the morning. The highest risk for severe weather develops midday to early afternoon.
According to the National Weather Service Chicago, severe storm timing is from approximately 11 AM to 6 PM CDT. While morning activity could shift the highest threat further southeast, damaging winds capable of downing tree limbs and isolated tornadoes are potential severe threats. Locally heavy rainfall may also lead to some flooding in affected areas.
The most intense activity is expected to impact communities including Kankakee, Watseka, and areas stretching towards Rensselaer, Indiana. Chicago and its immediate western suburbs are under a Level 2 threat. Travelers on I-55, particularly south and east of Joliet, should prepare for rapidly changing conditions and potential road hazards.

Looking ahead, a significant heat wave builds into the weekend, bringing peak afternoon heat indices above 100°F for Saturday and Sunday across the entire Chicagoland area. Evening heat indices are expected to remain in the 90s in Chicago. Residents should prepare for these extremely hot conditions by staying hydrated, wearing light clothing, taking frequent breaks in shade or air conditioning, and altering outdoor plans to minimize exposure during the hottest parts of the day. Warnings for severe weather remain in effect through Wednesday evening, with heat advisories likely to be issued for the upcoming weekend.
