Chicago, Illinois – Scattered thunderstorms are expected to fire up east of Interstate 39 by 4 p.m. Friday, threatening to make the afternoon commute across northern Illinois wet, stormy, and potentially dangerous.
According to the National Weather Service in Chicago, the greatest risk runs from 4 to 9 p.m. Friday, with damaging wind gusts over 60 mph, frequent lightning, and brief downpours possible. The storm zone includes major population centers such as Chicago, Joliet, and Rockford, with isolated hail also possible in the most intense cells.
Counties including Cook, DuPage, Lake, McHenry, and Will could see rapid storm development during peak travel hours. Roads like I-55, I-90, and U.S. 30 may experience reduced visibility and sudden slick conditions. Drivers are urged to delay travel if possible, keep phones charged, and have multiple ways to receive weather alerts.
While this system is not expected to produce widespread severe weather, any storms that do form could become strong quickly. Wind damage to trees or power lines is the main concern.
Storms are expected to exit the region by late evening, but additional watches may be issued Friday morning as conditions evolve.
