The wider storm
A strong cold front approached the Tennessee Valley and southern Appalachians during the late afternoon and evening hours of Monday, June 21. A warm and humid air mass ahead of the front (following the remnants of Tropical Storm Claudette) led to the development of numerous clusters of strong to severe thunderstorms that tracked from west to east. The main impact from these storms was damaging winds, with two dozen reports of wind damage in the form of down trees and power lines. A barn was destroyed in Roane County, and a metal frame building was damaged in Speedwell in Claiborne County. In addition to the damaging winds, golf ball sized hail occurred in Hancock County.
Began near Avondale Spgs (36.2900, -83.5000).
