Marine Thunderstorm Wind — Avon Point To Willowick Oh, Lake Erie

2022-08-29 · near Avon Point, Avon Point To Willowick Oh, Lake Erie

Event narrative

The Rocky River Buoy recorded a peak convective gust of 47 mph from an outflow-dominant squall line.

Wider weather episode

A surface low drifted eastward across far-northern Ontario during the evening of the 29th, which allowed Lake Erie and vicinity to reside in the warm sector as the low's trailing cold front approached slowly from the western Great Lakes. Moderate to strong MUCAPE, moderate effective bulk shear, and moderate to strong DCAPE resided over Lake Erie and vicinity. As an outflow-dominant squall line evolved generally eastward in this environment, it generated scattered gale-force peak wind gusts along the northern Ohio shore. Despite the squall line's slight outflow-dominance, several waterspouts managed to develop along the downshear gust front just offshore Cleveland.
