Marine Thunderstorm Wind · Lake Erie

South Bass Island C-MAN Station (SBIO1) recorded a peak wind gust of 45 mph from passing thunderstorm.

A surface low moved east-northeastward from southern Lake Michigan to Lake Ontario during the morning through early afternoon of April 1st. Simultaneously, the low's trailing cold front moved from the southwestern Great Lakes and Middle MS Valley toward central NY and the Upper OH Valley. Scattered multicell showers and thunderstorms persisted generally northeastward and eastward ahead of, along, and just behind the surface cold front during the wee hours of the 1st and again during the late morning through early afternoon of the 1st. These showers and storms encountered moderate to strong effective bulk shear, weak DCAPE, and weak MUCAPE. Despite the marginally-favorable thermodynamic environment, showers and storms generated sporadic convective gusts that peaked at gale-force to hurricane-force during the wee hours of the 1st and again during the late morning through early afternoon of the 1st.
