Flash Flood — Jun 28, 2025
Showers and thunderstorms developed along a frontal boundary that was moving south into the Ohio Valley.
Flood — Jul 27, 2025
A weak cold front sagged south through the Great Lakes region, stalling out as a stationary front through the Ohio Valley. This boundary, combined with a very warm and humid airmass, sparked showers and thunderstorms throughout the afternoon and into the evening hours on the 27th. Some of these storms produced damaging winds and heavy rainfall, which lead to instances of flash flooding.
