EF-1 damage was identified at one structure near this highway crossing, and considerable tree damage consistent with EF-1 intensity tornadic winds were observed along the highway right of way. The tornado then proceeded east-northeastward to Franklin.

The most significant damage occurred in the city of Franklin. Within a two-block long corridor on the south side of Franklin, the team confirmed EF-3 intensity tornado damage at 2 residences. Peak wind speeds at these sites were estimated at 140 mph. A number of additional structures on the south side of Franklin exhibited EF-1 and EF-2 intensity damage.

The tornado continued from Franklin east-northeastward along US 79, crossing the Navasota River into far western Leon County. The path width of the tornado contracted to about 100-200 yards over eastern Robertson County, and damage was mainly EF-0 in intensity, confined mainly to snapped tree trunks and large branches. The tornado dissipated in extreme western Leon County, 4 miles south-southwest of Marquez.
