The wider storm
On July 17, 2025, a slow-moving cold front interacted with a humid and unstable airmass over central and southern Indiana. This synoptic setup led to isolated but potent thunderstorms that produced a primary hazard of flash flooding, rather than the damaging winds or tornadoes seen in previous events. The day's weather pattern was dominated by a stalled cold front, which served as a focal point for storm development. Throughout the afternoon and evening hours, scattered thunderstorms formed, with the most significant activity concentrated in Owen and Daviess counties. The slow movement of these storms allowed for very efficient rainfall, leading to isolated flash flooding.
Began near Washington (38.6697, -87.1865).
