Severe storms anticipated in Chicago on Wednesday
A powerful storm system will bring rounds of showers and thunderstorms to the Chicago area Tuesday night through Wednesday evening.
Some storms overnight into early Wednesday could produce hail and heavy rainfall, but the overnight severe risk is small.
On Wednesday, there will be rain and thunder in the morning with temperatures in the 40s. By the mid-afternoon, a warm front will surge north across the area — allowing temperatures to quickly climb into the 60s and 70s.
The warm front may spark numerous severe thunderstorms Wednesday afternoon into the evening hours. These afternoon and evening storms pose an enhanced threat of tornadoes, large hail, and damaging winds.
Much cooler air arrives for the end of the week and over the weekend, with highs in the 40s.
