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 and supercell thunderstorms occurred along and ahead of the cold front in northern OH. These storms produced severe hail, damaging convective gusts, and two tornadoes in a warm sector comprised of moderate to strong MUCAPE and effective bulk shear, respectively, mixed-layer lifting condensation levels near 750 to 1500 meters AGL, and strong surface-based effective storm-relative helicity near 150 meters squared per second squared.
