Extensive roof damage to a building along with surrounding tree damage with limbs down east of Mount Vernon, OH.

An MCS moved southeastward across Central Ohio in the late morning into the early afternoon on June 6, 2026 moving along the northern edge of a surface high pressure situated in the southeastern United States. Ahead of the MCS, strong warm air advection allowed dew points to rise up into the mid 60s with surface based CAPE of around 1000 J/kg and effective bulk shear of 30 knots creating a severe wind threat.

Later in the evening on June 6, 2026, a cold front moved south from Michigan and southern Ontario into an environment of around 1500 J/kg of ML CAPE and effective bulk shear of around 40 knots. This created a severe wind threat along the western shores of Lake Erie in Ohio.
