Chicago, Illinois – Severe storms are expected to rapidly develop by 3 p.m. Thursday, bringing a risk of tornadoes, large hail, and damaging winds across central and eastern Illinois during the afternoon commute.
According to the National Weather Service in Chicago, the main window for severe weather runs from 3 p.m. to 9 p.m. as a cold front pushes through the region. Storms may produce wind gusts up to 60 mph and hail larger than 2 inches in diameter, with the greatest tornado risk focused south of a line stretching roughly from Ottawa to Kankakee.
Communities including Bloomington, Champaign, Kankakee, and areas along Interstate 55 and Interstate 57 face the highest threat for rotating storms. Storm motion is expected to track east at 50 to 60 mph, meaning conditions can deteriorate quickly with little warning time.
Residents are urged to have multiple ways to receive alerts, including cell phone notifications, and not rely solely on outdoor warning sirens. If warnings are issued, move to an interior room on the lowest floor and wear sturdy shoes in case of debris.
Storms are expected to weaken later Thursday night, but additional alerts could be issued if conditions intensify during the afternoon hours.
