EF1 tornado in Huron County, Ohio

This EF1 tornado with estimated peak winds of 100 mph travelled east-northeastward during its lifespan and began on the south side of Collins, near the intersection of U.S. Route 20 and Hartland Center Road. The tornado produced mainly tree damage along its path in Huron County, although some tree limbs or entire trees were downed onto residences, which caused minor structural damage. As the tornado progressed east-northeastward, it crossed Derussey Road, Wakeman Townline Road, Ogan Road, Fitchville River Road, West River Road, North River Street, Lincoln Road, and Butler Road before entering Lorain County near the Firelands Boy Scout Reservation.

A slow-moving cold front was draped west to east across the southern Great Lakes during the day of June 18th, 2025, with low pressure near Chicago drifting east toward southern Ontario. An upper-level shortwave trough moving eastward across the southern Great Lakes during the afternoon brought scattered showers and thunderstorms to portions of northern Ohio, with slow-moving and back-building storms along a lake breeze front in far-northeast Ohio, which brought flash flooding to portions of Ashtabula County. A quasi-linear convective system organized and strengthened across Illinois and Indiana during the afternoon and early evening hours, and moved eastward across northern Ohio during the evening. This line of storms generated widespread damaging straight-line wind gusts up to approximately 80 mph and three tornadoes in northern Ohio. All of these storms occurred amidst moderate to strong effective bulk shear and primarily weak to moderate MUCAPE.
