Thunderstorms will continue throughout the day, but the strongest storms could hit Chicago between 6 p.m. and 11 p.m., the National Weather Service said in its forecast.

“In addition to the risk for severe weather, some of the thunderstorms will produce torrential downpours,” the weather service said. “If thunderstorms repeatedly develop and move over the same area this evening, localized flash flooding is likely with isolated rainfall totals in excess of 3 inches possible.”
Friday’s forecast calls for partly sunny skies and highs in the low 70s for inland areas, the weather service said. Temperatures near the lakeshore could reach the mid-60s.
The weekend could see consistent high temperatures in the mid-60s, and a possible thunderstorm Sunday, the weather service said.
