- A violent tornado quickly developed across Woodford County during the mid afternoon. This tornado was at F4 intensity as it demolished a manufacturing plant 4 miles west of Roanoke. Although 140 people were inside at the time, all escaped injury by reaching storm shelters a few minutes before the tornado's arrival. Steel beams and metal siding from the plant were found approximately three quarters of a mile east in a farm field. Four farmsteads east of the plant were severely damaged or destroyed.
