Nashville, Tennessee – Drivers and outdoor workers across Middle Tennessee are facing another sweltering day, as heat index values climb above 105° and in some places spike to 110° through late Wednesday. West of the Cumberland Plateau, the risk for heat illness is highest, and many areas are expected to surpass 100° heat indices by late morning.
According to the National Weather Service in Nashville, the most extreme conditions will impact counties including Davidson, Montgomery, Maury, and Wayne, where feel-like temperatures will reach dangerous levels. Columbia, Clarksville, and Waynesboro are all forecast to hit 107° to 110°, prompting advisories for heat danger and possible thunderstorms later today.
Residents are urged to stay hydrated, avoid strenuous outdoor activity between 11 a.m. and 8 p.m., and check on neighbors, children, and pets. Never leave anyone in a parked car, even briefly. Heat-related illness can happen quickly, even outside of official heat waves.
Thunderstorms could develop during the afternoon and evening, posing additional risks. If you hear thunder, seek shelter immediately—preferably somewhere with air conditioning.
Extreme heat advisories will remain in effect through Wednesday, with more alerts possible if conditions worsen. Stay tuned for updates as the heat persists across the region.
