Wider weather episode
A weak trough and remnant outflows initiated afternoon thunderstorms. Initial single cell development across eastern Ohio ultimately congealed along propagating cold pools and surged southeast. A rich moisture environment was in place with 1000-2000 J/kg MLCAPE and near 30 knots of effective shear. The storms rolled into more favorable DCAPE, as high as 1200 J/kg, farther southeast, and repeated updrafts along outflow produced swaths of damaging wind.
