Details regarding the exact extent of the damage are still varying, but several homes have lost large portions of their roofs in the southwestern Ohio area. I looked at the 00z sounding from Wilmington OH, which was VERY close to the area in question, and it definitely supports a tornado potential; SBCAPE around 1500 J/Kg, 0-1km SRH >200 m2/s2, T/Td of 77/72, and a resulting LCL of 300m. Pictures from various news sites show what appears to be an extremely large tornado moving through a forested area behind a neighborhood, though thankfully no injuries have been reported. The tornadic thunderstorms have since dissipated, but new convection has devoloped behind them in the past hour, which should remain below severe limits. I can't help but note that the SPC omitted the region from any type of risk (or mention) of severe thunderstorms.
