Springfield, Ill. – A late-summer warm stretch will give way to a taste of fall across Illinois by midweek, as a cold front pushes through the region bringing showers, thunderstorms, and a sharp drop in temperatures. Highs near 80 are expected through Tuesday before conditions turn unsettled Wednesday.
According to the National Weather Service in Lincoln, scattered thunderstorms could develop Wednesday afternoon and evening, especially across central Illinois. Rain chances are expected to range from 20% to 50% during the day, increasing to 30% to 60% overnight. Behind the front, highs on Thursday will only reach the upper 60s, marking one of the coolest days since early summer.
Peoria, Springfield, and Bloomington will all see highs in the low 80s through Tuesday, but readings fall quickly with Thursday’s chill. Overnight lows will dip into the upper 40s by Thursday night, prompting residents to prepare for brisk mornings. Travelers should monitor changing conditions Wednesday, especially during the evening commute, when wet roads and reduced visibility are possible.
Cooler, fall-like weather will linger into Friday with highs in the low to mid-70s. Another stretch of warmer air may not arrive until the weekend.
