CLEVELAND, OH — Storm coverage exploded across the Lake Erie shoreline Sunday evening as a frontal boundary moved over the lake, triggering frequent lightning, pockets of small hail, and gusty winds across northeastern Ohio, with a few cells even showing signs of minor rotation.
Frontal Boundary Sparks Rapid Storm Development
As the frontal boundary crossed Lake Erie Sunday evening, storm coverage expanded quickly, producing widespread lightning activity and scattered pockets of small hail across the region. Forecast radar valid around 7:38 p.m. EDT shows a broad line of storms stretching from near Detroit and Toledo eastward across the lake toward Erie, Pennsylvania, with the most intense cells concentrated directly over the water between Cleveland and Ashtabula.
A few cells tracking across the lake displayed minor rotation, raising the potential for isolated waterspouts to develop over open water as the storms moved through.
Sharp Divide Splits Rain Coverage East and West
Forecasters identified a clear dividing line separating areas likely to see active weather from those expected to stay dry. Communities east of the boundary, including Cleveland, Ashtabula, Youngstown, and Erie, were expected to see a mix of rain and gusty storms through the evening. Areas west of the line, including Toledo, Findlay, and Bowling Green, were expected to see little to no activity from this round.
No Severe Weather Expected Despite Active Radar Signature
Despite the fast-developing storm coverage and lightning-heavy activity, forecasters emphasized they were not anticipating true severe weather with this event. Meteorologists said they would continue monitoring how the storms behaved as they tracked across the open waters of Lake Erie, given the tendency for lake-effect instability to occasionally intensify convection overnight…
