Thunderstorm Wind in Knox County, Ohio

Multiple tree limbs downed about 2.7-miles ENE of Centerburg and tree downed near intersection of Pleasant Valley Road and Keys Road, about 4-miles WSW of Mount Vernon.

A mid/upper-level trough lingered over the Great Lakes and Middle to Upper OH Valley during the afternoon of the 23rd through early evening of the 25th as embedded shortwave disturbances traversed northern OH generally from west to east. Multiple surface trough axes associated with the disturbances moved generally eastward across northern OH. Low-level convergence and associated ascent along surface trough axes acted as a focus for scattered thunderstorm development during the early evening of the 23rd. These multicell thunderstorms generated isolated straight-line convective wind damage as they persisted northeastward and encountered moderate MUCAPE and marginally-moderate effective bulk shear. Low-level convergence and associated ascent along a Lake Erie lake breeze front generated scattered thunderstorms in the Cleveland metro area during the afternoon of the 25th. The pulse thunderstorms produced isolated severe hail and straight-line convective wind damage as they persisted generally southward and encountered strong MUCAPE and weak to marginally-moderate effective bulk shear.
