Portage County Flood History

Flash Flood — Jul 10, 2025

Thunderstorms developed along a slow moving frontal boundary during the afternoon, as weak low pressure moved northeast across the lower Great Lakes region. During the early afternoon hours, mixed layer CAPE values of 2000 j/kg helped fuel thunderstorm development as effective deep layer shear increased to 20-30 kts. Storms were weakly organized and slow moving, producing isolated damaging wind...

Flash Flood — Aug 17, 2024

At the surface, a low wobbled southeastward from the northwestern Great Lakes to southern Lake Huron during the early evening of the 16th through early evening of the 17th. Simultaneously, the attendant warm front moved northeastward from northern Lake Michigan and central Lake Erie to near the northern shore of Lake Ontario and Upper St. Lawrence River Valley, while the trailing cold front mov...

Flash Flood — Aug 8, 2024

A surface trough was oriented south to north across northeast Ohio during the afternoon and early evening of August 8th, 2024, with then Tropical Depression Debby centered over the Carolinas. Strong tropical moisture advection northwestward into the area and modest mixed layer CAPE (1000 j/kg) allowed for thunderstorm development throughout the mid afternoon into the early evening hours, with t...

Flash Flood — Aug 3, 2024

A slow moving cold front moved south into far northern Ohio before stalling during the morning hours of August 3rd, 2024, as weak low pressure moved east across the lower Great Lakes. Most of northeast Ohio remained in the warm sector, characterized by 1000 j/kg MLCAPE, precipitable water values near 1.75, slow storm motions due to a lack of deep layer shear. Thunderstorms developed during the ...

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...
