Chicago, Illinois – A growing risk of severe storms could disrupt travel and evening plans across northern Illinois Monday, with impacts expected to begin as early as 4 to 6 p.m. and intensify into the night.
According to the National Weather Service in Chicago, the region is entering a setup supportive of severe thunderstorms with all hazards possible, including damaging wind gusts, large hail, and a few tornadoes. Confidence is increasing that storms will develop Monday, though exact timing and locations of the strongest activity remain uncertain.
The highest concern stretches from the Chicago metro west toward Rockford and south along the I-55 corridor, including Joliet and Kankakee. Major routes such as I-90, I-94, and I-290 could see sudden slowdowns during the evening commute as storms bring heavy rain and frequent lightning.
Conditions remain quiet through the weekend, with highs in the 60s to mid-70s and a mix of sun and clouds Saturday and Sunday. That break provides a window to prepare before weather conditions deteriorate rapidly Monday afternoon.
Residents should review severe weather plans now, secure outdoor items, and ensure multiple ways to receive warnings. Charge devices ahead of time in case of outages. Updates are expected through Sunday as the storm track and timing become more precise, and alerts may expand if confidence continues to increase.
