A supercell thunderstorm produced hail up to golfball sized,
a swath of straight-line winds up to 80 miles per hour, and
a brief weak tornado across southern DeKalb County. Wind damage
consistent of a brief weak tornado were found along County
Road 51 about 1/2 mile northeast of state highway 68. The
tornado snapped large tree branches at a residence, then tracked
into a grassy field where convergent patterns were found.
The tornado downed a couple of trees along nearby Interstate
59. Straight-line winds just south of the intersection of
County Roads 246 and 28 downed, snapped, or uprooted a few
trees, destroyed a large chicken barn, and tore a portion
of a roof off a trailer home. Other trees or large tree limbs
were downed in and near Crossville and Collinsville along
the Highway 68 corridor. The storm moved into adjacent Cherokee
County also producing wind damage and large hail in the community
of Sand Rock.
