Flash Flood — Apr 25, 2025
Broad, quasi-zonal mid/upper level flow was present over the Great Lakes and Ohio Valley on April 25th, 2025, with surface low pressure slowly moving east across the southern Great Lakes. Northern Ohio was firmly entrenched in the warm sector of this system with a warm front just north of Lake Erie. Widespread rain showers with embedded thunderstorms developed across Northern Ohio during the af...
Flash Flood — Aug 13, 2025
A slow moving cold front moved west to east across northern Ohio during the afternoon and evening hours of August 13th, 2025. A warm and moist environment, characterized by MLCAPE values between 1500-2000 j/kg and precipitable water values near 1.8 inches, and weak deep layer shear promoted slow moving thunderstorms producing efficient rainfall. An area of slow moving and training thunderstorms...
Flash Flood — Jun 18, 2024
Northern Ohio resided within the warm and humid sector along the northwestern flank of the Bermuda-Azores subtropical high during the late morning of the 17th through late evening of the 20th. In addition, a cold front drifted southeastward from the western Great Lakes to Lake Erie and northwest OH by the evening of the 20th.||Well-ahead of the the cold front, scattered multicell thunderstorms ...
Flood — Feb 17, 2022
A southeastward-moving surface cold front across southern Lower MI and northern IN approached northwest OH during the early morning of the 17th. The surface pressure gradient tightened in northwest OH as the cold frontal surface trough interacted with a surface ridge axis that remained anchored near the coast of the Carolinas and Georgia. This tightening surface pressure gradient and apparently...
Flash Flood — Aug 25, 2021
A broad ridge of high pressure was present over the eastern CONUS, with a warm, humid airmass in place over northern OH. PWAT values were near 1.9 and MLCAPE values ranged from 1000-2000 j/kg. Steering flow was minimal, which allowed for slow moving thunderstorms. A single thunderstorm developed over Warren and remained stationary for nearly an hour, before an upstream thunderstorm over Portage...
