An occluded surface low meandered near the eastern shore of Lake Superior during the late morning through early evening of the 12th. Simultaneously, the trailing cold front swept southeastward from southeastern Lower MI and northern IN to central Lake Erie and north-central/west-central portions of OH. Multiple multicell thunderstorms occurred over Lake Erie, along and ahead of the cold front. These storms produced gale-force peak convective wind gusts along the OH shore as the storms encountered moderate to strong MUCAPE and effective bulk shear, respectively.
