A slow-moving cold front progressed across Illinois during the afternoon and evening of June 30th, 2025, interacting with a very moist, unstable airmass and resulting in clusters of thunderstorms. Eventually, these clusters of storms grew into a slow-moving complex that produced heavy rain along and southeast of the I-70 corridor, with rainfall amounts ranging from 1 to 3.5 inches. This resulted in a few instances of flash flooding. These areas of flooding persisted into the early morning hours
