Grazulis narrative: Moved northeast from six miles west of Salvisa to one mile east of Ballard. Five barns were destroyed, two of which had concrete foundations. A house and a metal silo were destroyed. Two cars and a truck were destroyed, and a 400-gallon water tank was moved three-quarters of a mile. A 16-inch rafter was driven into the ground.
Noted discrepancies: Grazulis lists this tornado at 11:10pm. SPC/NCDC stop this tornado at Salvisa, but Grazulis takes it into Anderson County, ending it one mile east of Ballard. In Storm Data the tornado touched down six miles west of Salvisa in Mercer County (one mile east of Ballard) and moved northeast along Stratton Road, Kirkwood Road, Gash Road, and Hickory Grove Road, all of which are in Mercer County. At this point, prefer to plot this tornado only in Mercer County.
