Southern middle Tennessee experienced a portion of a much larger outbreak of tornadoes and severe weather from the Ohio Valley south through the Tennessee Valley to the Gulf Coast in advance of a strong cold front. The storms came in two waves, one during the mid to late morning, and another throughout the afternoon hours.  One of the morning supercell storms produced a tornado that made a very short track (1/4 mile) into far southwest Franklin County.  This storm was one of a pair of tornadic supercells which tracked through Limestone and Madison Counties in north central Alabama.
During the early afternoon, numerous thunderstorms re-erupted across north Alabama which moved into southern Tennessee, including several supercells.  Most of these storms were large hail producers, including up to baseball sized in Franklin County during the mid afternoon.  One supercell produced an isolated tornado in the Boonshill community in Lincoln County.  The cold front moved through during the mid to late evening, ending the threat of severe weather.
