High Wind in Sullivan, Tennessee

Wind gusts above 40 mph were recorded in multiple counties across the area, including: Washington, Sevier, Knox, Polk, Blount, McMinn, Monroe, Campbell, and Hamilton.

A strong low level shortwave weather system coupled with very strong upper level winds helped bring a moderate mountain wave event to the East Tennessee mountains, followed by strong to high winds during the midday hours thanks to efficient mixing of high winds to the surface.
