The Brief Scattered showers and thunderstorms could bring heavy rain, gusty winds and an isolated severe storm this afternoon and evening, mainly southwest of Chicago. Warmer weather returns Friday and Saturday before additional chances for storms arrive late Saturday and continue into early next week. We still have a marginal (1/5) risk for severe weather in our southwestern counties including portions of DeKalb, Kendall, Kankakee, Grundy and LaSalle counties. Friday will be warmer with partly sunny skies and highs in the mid 80s. Tuesday, we are looking at partly sunny skies and highs around 80.
