Chicago, Illinois – Summer storms are set to interrupt the dry spell in Chicago, with thunderstorms likely to roll in after 1 p.m. Tuesday, July 15. Motorists on I-55 and city streets should be ready for sudden downpours, slick roads, and potential lightning delays. Chicago’s afternoon commute could get messy, so pack an umbrella and allow extra travel time.
According to the National Weather Service, a chance of showers develops early Tuesday, with thunderstorms possible after 1 p.m. The risk peaks Tuesday afternoon as moisture builds across Cook County, impacting not only Chicago but also Cicero, Oak Lawn, and Oak Park. While Tuesday morning brings sunshine and a high near 85°F, conditions will shift quickly as storms approach.
Showers may linger into Wednesday, with another round of thunderstorms likely by Wednesday night. Commuters and outdoor workers should monitor alerts and avoid flooded areas. The NWS advises staying off roads during the heaviest rain and securing outdoor items to prevent wind damage.
By Thursday, storms remain possible—especially in the morning—but drier, milder air is on the way for Friday and Saturday. Highs will trend in the upper 70s to low 80s, with lower humidity making for pleasant summer days. Next weekend looks ideal for outdoor plans across the city, though another round of scattered storms could return by Sunday.
Rain and thunderstorms could disrupt plans through Thursday, but summer warmth and sunshine are set to return Friday into Saturday. More alerts may be issued if the storm track shifts, so check back for updates.
