Springfield, IL – A stormy stretch is setting up across central Illinois this week, with repeated rounds of showers and thunderstorms expected through Saturday and the greatest severe weather risk arriving Thursday.
According to the National Weather Service in Lincoln, unsettled conditions will continue across much of the state through the end of the workweek. Storms could redevelop at times Wednesday, but forecasters highlight Thursday as the day with the strongest potential for severe thunderstorms across central Illinois.
Cities including Springfield, Peoria, Bloomington, Decatur, and Champaign could see periods of heavy rain, frequent lightning, and gusty winds through the week. Forecasters warn that Thursday’s storms may produce stronger wind gusts and isolated severe weather as warmer air pushes north ahead of an approaching cold front.
Drivers along major corridors like Interstate 55, Interstate 74, and Interstate 72 may encounter reduced visibility during heavier downpours, particularly during the afternoon and evening commute windows later this week. Residents should secure outdoor items, keep phones charged, and stay alert for possible warnings if storms intensify Thursday.
Additional thunderstorm rounds may redevelop Friday and Saturday before a stronger cold front moves through. That system should push storms out and bring cooler, drier air across Illinois by early next week.
