Chicago, IL – Fog slowed commuters along I-57 this morning, and storms could worsen travel across northern Illinois through Thursday. Residents should plan for reduced visibility and scattered flooding, especially south of I-80.
According to the National Weather Service in Romeoville, showers and thunderstorms are expected this afternoon and into Wednesday. While widespread severe weather remains unlikely, some storms may bring heavy rainfall and minor flooding near the Kankakee River. A High Swim Risk also continues for Lake Michigan beaches through midweek, making swimming dangerous.
Drivers across Chicago and suburbs such as Joliet, Aurora, and Waukegan should remain cautious. Fog and wet pavement could create slick travel conditions during morning and evening commutes. Extra time on the road is advised, particularly near construction zones and interstate ramps.
Rain chances lessen by Thursday, with sunshine and warmer conditions building toward Friday. Fall’s first full week finishes on a calmer note, but cooler nights will linger, a hint of the season ahead.
Residents should avoid swimming in Lake Michigan, watch for ponding on roads, and secure outdoor items ahead of Wednesday’s gusty winds. Spotter activation is not expected, but updated advisories may be issued if rainfall intensifies.
The unsettled stretch wraps by late Thursday, followed by a dry, sunny Friday. Cooler, breezy weather may return over the weekend as northern Illinois settles further into fall.
