Flash Flood — Wabash, IL

Jul 28, 2022

Flood Cause
Heavy Rain

A large complex of thunderstorms moved east across southern Illinois during the afternoon and evening hours. Very heavy rainfall rates contributed to isolated instances of flash flooding. The complex of thunderstorms developed ahead of a 500 mb disturbance over central Missouri, which moved eastward into a very moist and unstable air mass. Precipitable water values were around 2.25 inches, and surface-based cape exceeded 2000 J/kg. Soils across the region were quite moist due to repeated thunder
