Wider weather episode

A cold front drifted south-southeastward from near the northern shore of Lake Erie and southern Lower MI to near the southern shore of Lake Erie and far-northwestern OH during the evening of the 14th as a warm and relatively-moist sector preceded the front in northern OH. Multicell and supercell thunderstorms occurred along and ahead of the front, and persisted generally eastward. Severe hail, some large, and isolated straight-line convective wind damage occurred as the storms encountered weak to moderate MUCAPE, relatively-steep midlevel lapse rates near 7C/km, and moderate to strong effective bulk shear. Three separate supercells spawned a tornado amidst favorably-strong, surface-based effective storm relative helicity and favorably-low mixed layer lifting condensation levels less than 1500 meters AGL. The training supercell thunderstorms with heavy rainfall produced isolated flash flooding as well.
