The core of a potent thunderstorm quickly intensified in the vicinity of Interstate 65 in Chilton County during the early-morning hours. Large hail to around golf ball size resulted from this cell, with significant straight-line wind developing as the core dump breached the low-level stable layer.
Extensive wind damage began in Chilton County (just west of Thorsby & Jemison) where maximum winds were estimated in the range of 80 to 90 MPH. The wind damage continued eastward through Coosa County & Tallapoosa County, where maximum winds were estimated in the range of 70 to 80 MPH. The damage, as confirmed by a NWS survey team, was the result of straight-line wind consisting of (1) numerous snapped & uprooted hardwood/softwood trees, (2) tree fall onto structures, (3) tree fall onto campers, especially notable in Wind Creek State Park where several were crushed, (4) damage to roofs, siding, overhangs, awnings, outbuildings and, (5) a case of wind-driven hail causing severe exterior damage to buildings in the Kellyton area of Coosa County. Wind damage became less intense & more sporadic as the storm entered Chambers County. At least 3 injuries were reported, all in Tallapoosa County.
