The episode as NWS IWX wrote it up.
Strong mesoscale convective vortex (MCV) moved out of northern Illinois into southern Lower Michigan, with a line of thunderstorms trailing the feature. An outflow boundary moved south out of Lower Michigan into the area. These features entered an unstable atmosphere, with upwards of 4000 j/kg of CAPE across northwestern Ohio. Numerous storms developed across the area and moved east. Sporadic wind damage was reported with the largely outflow dominant north-south line of storms as it moved across the area.
