Chicago, Illinois – Chicago-area drivers could encounter scattered showers and isolated thunderstorms before Wednesday’s morning commute, followed by another round of storms Wednesday afternoon concentrated east of Interstate 55.
According to the National Weather Service Chicago office, rain and isolated thunderstorms carry a 20% to 30% chance Tuesday night, mainly north of Interstate 80. Wednesday brings a 20% to 60% chance of showers and storms, with the greatest potential mainly east of I-55. High temperatures will range from 81 to 85 degrees.
The timing puts Chicago and surrounding northeastern Illinois communities at risk for brief travel disruptions Wednesday.
