EF1 tornado in Summit County, Ohio

This tornado had peak intensity of EF1, estimated peak winds of 104 mph, and travelled generally southeastward during its lifespan. The tornado began at a commercial warehouse along Columbia Road in Richfield, where the east end of the roof was removed. Eleven empty semi truck trailers were blown-over in the same general location. As the tornado continued moving southeastward, intermittent tree and power pole damage was noted along Columbia Road. Trees were downed or snapped in different directions. This tornado ended on the north side of the I-80 Cuyahoga Valley Bridge, just west of Riverview Road in Boston, where additional snapped trees were found.

Between about daybreak and nightfall on August 6th, a wavy surface cold front drifted generally southward from northern OH and near the NY/PA line to southern OH and the northern Mid-Atlantic states. This front separated a warm and humid air mass to its north from a warmer and more-humid air mass to its south. A line of multicell thunderstorms persisted southeastward across Mahoning County during the early afternoon and produced localized straight-line convective wind damage. During the late afternoon through early evening, a line of multicell thunderstorms moving eastward across northwest OH merged with a separate line of multicell thunderstorms moving southeastward across western and central Lake Erie. These lines merged to form a more-extensive QLCS that persisted southward and eastward across northern OH. Ahead of these storms, additional multicells and a few transient supercells developed in northeast OH.

All of these storms occurred amidst weak to moderate MUCAPE and moderate to strong effective bulk shear. Extensive straight-line convective wind damage occurred in northern OH, especially northeast OH, as storms also encountered moderate DCAPE and steep low-level lapse rates. The QLCS also produced five mesovortex-related tornadoes amidst large surface-based ESRH of at least 150 meters squared per second squared and favorable mixed-layer LCL's less than 1k meters AGL.
