Flash Flood — Jul 25, 2025
Overnight sub-severe convection and remnant boundaries from said convection acted as initiating mechanisms for development later in the morning and afternoon hours. A moist and unstable environment with up to 2500 J/kg MLCAPE and 30 knots of effective shear supported storm organization and maintenance. Favorable DCAPE between 800-1000 J/kg resulted in some instances of damaging wind. In additio...

Flood — Apr 3, 2024
Several rounds of showers and thunderstorms prompted a widespread flash flood problems across the Ohio River Valley on April 2nd to April 3rd. The synoptic pattern across the CONUS was a slow moving and deep elongated trough over the Great Plains phasing with a ejecting trough over the Midwest that created an area of converging moisture over eastern Ohio and western Pennsylvania. Overall, over ...
Flood — Apr 1, 2024
Training showers created isolated flooding in portions of the region early Monday morning (April 1st). Convection originated in the Midwest along a stationary boundary. With zonal flow over Illinois, Indiana, and Ohio, due to an elongated trough over the West Coast, convection trained from west to east. CoCoRaHS observers measured 1.50 to 2 inches of rain along I-70.
