Springfield, Illinois – Severe thunderstorms could pound central and eastern Illinois through Wednesday evening, bringing threats of damaging winds, large hail, and a possible tornado, especially near and east of the I-55 corridor. Cities like Bloomington, Decatur, and Champaign may see the most intense impacts.
According to the National Weather Service in Lincoln, scattered storms will develop Tuesday evening with heavy rain and gusty winds. By Wednesday, the chance for severe storms jumps to 70%, with highs in the mid-80s and storm cells capable of producing hail, 60+ mph wind gusts, and isolated tornadoes.
Drivers along I-55 and connecting roads should prepare for poor visibility, sudden wind shifts, and potential debris on roadways. Residents are urged to secure loose outdoor items, avoid unnecessary travel during storm windows, and have phones fully charged in case of power outages.
This storm system marks one of the more active mid-June weather patterns in recent years. The threat will ease by Thursday, with clearing skies and highs in the low 80s, but any warnings or watches may extend depending on storm development.
