Nashville, Tennessee – Brutal summer heat is gripping Middle Tennessee as heat index values soar to 107° through Friday evening, prompting a regional summer weather alert.
According to the National Weather Service in Nashville, a Heat Advisory remains in effect until 7 PM CDT Friday for nearly 50 counties, including Davidson, Sumner, Wilson, Montgomery, Rutherford, and Williamson. Daytime highs will reach 98° Thursday with heat index values topping 106°, before slightly easing to 94° Friday.
