EF0 tornado in Trumbull County, Ohio

An EF0 tornado with estimated peak winds of 80 mph impacted portions of Southington and Champion Townships in Trumbull County. The tornado began near OH Route

305, east of Hoffman Norton Road. Damage in this location included significant damage to a garage and some downed trees and roofing damage, indicative of 80 mph tornadic winds. The tornado continued northeastward to Oak Hill Drive, where additional downed trees caused damage to a couple homes. The tornado continued northeastward to Downs Road NW, where more downed trees caused more home damage. The tornado moved farther northeastward and caused more tree damage west of Mahoning Avenue (OH Route 45), but the tornado dissipated before reaching the road.

At the surface, an occluded low drifted from northeastern WI to the central Upper Peninsula of MI during the early afternoon through early evening of the 17th. Simultaneously, the low's attendant warm front drifted eastward across central Lake Erie and far-western PA, and the low's attendant cold front swept eastward from near the northwest OH/northeast IN border and central IN to near the OH/PA border, which caused the warm sector to shrink with time. Scattered multicell thunderstorms and a few supercell thunderstorms developed along and ahead of the cold front, and persisted generally eastward across northern OH as the storms encountered weak to moderate MUCAPE and DCAPE, respectively, and moderate to strong effective bulk shear. This environment allowed storms to produce damaging hail and straight-line convective wind gusts, respectively. Three tornadoes also occurred amidst favorably-low mixed layer lifting condensation levels less than 1500 meters AGL and favorably-strong, surface-based effective storm-relative helicity.
