Thunderstorm Wind in Cannon County, Tennessee

A combination of sentinel satellite imagery, drone video, and damage photos indicate a small but intense 250-500 yards wide microburst caused significant damage from Hollow Springs Road in Cannon County to Pedigap Road in Warren County. The metal roof of a barn-style home at 5990 Hollow Springs Road was partially blown off and the home was shifted slightly off its foundation, causing $100,000 in wind and water damage. Winds were estimated up to 75 mph in this area. Further to the east, a video of the microburst was taken at an automotive business on Jim Cummings Hwy, where winds were also estimated up to 75 mph. Major tree damage occurred from north of McMahan Rd to north of Pedigap Rd, with dozens of trees snapped and uprooted. A silo on Parker Rd was also destroyed and a barn on Pedigap Rd was heavily damaged. Winds were estimated up to 90 mph in this area. No injuries were reported, and damages are a rough estimate.

A line of thunderstorms moved through Middle Tennessee during the late morning and early afternoon hours of August 7, 2023. Damaging straight-line winds were the primary threat with this line, especially for areas roughly along and south of Interstate 40. While this line of thunderstorms was severe as it crossed the Tennessee River, it significantly strengthened as it moved east of Interstate 65 with estimated winds of 70 to 95 mph across the Cumberland Plateau. Numerous reports of downed trees and powerlines were received with many of these also damaging homes and vehicles as well. The worst damage occurred across Cannon, Coffee, Warren, and Van Buren counties. Six separate microbursts and downbursts were identified that caused most of the significant damage in this area.
