Nashville, Tennessee – Middle Tennessee is entering a prolonged stretch of dangerous summer heat beginning late Monday morning, with heat index values expected to climb as high as 109 degrees through Thursday evening. The extended period of oppressive heat and humidity will significantly increase the risk of heat-related illnesses, particularly during the afternoon and early evening hours.
According to the National Weather Service in Nashville, an Extreme Heat Warning is in effect from 11 a.m. Monday through 8 p.m. Thursday for much of Middle Tennessee west of the Cumberland Plateau. The warning includes Nashville, Clarksville, Murfreesboro, Franklin, Columbia, Lebanon, Gallatin, Hendersonville, Springfield, Dickson, Cookeville, Mount Juliet, Smyrna, Shelbyville, Lawrenceburg, Pulaski, Waverly, Waynesboro and dozens of surrounding communities.
Heat index values are expected to peak near 109 degrees each afternoon as high temperatures combine with elevated humidity. The multi-day nature of the event will allow heat stress to build over time, increasing the danger for older adults, young children, outdoor workers, people with chronic medical conditions and anyone without reliable air conditioning.
Residents are urged to drink plenty of water, stay in air-conditioned buildings whenever possible and avoid strenuous outdoor activities during the hottest part of the day. If work outside is unavoidable, wear lightweight, loose-fitting clothing and take frequent breaks in shaded or cooled areas. Know the signs of heat exhaustion and heat stroke, and seek immediate medical attention if symptoms become severe.
Check on elderly neighbors, family members and others who may be especially vulnerable to the heat, and never leave children or pets inside parked vehicles, where temperatures can become life-threatening within minutes.
The Extreme Heat Warning remains in effect through Thursday evening, and additional heat-related alerts could be issued if dangerous conditions persist. Continue monitoring updates from the National Weather Service and local emergency management officials throughout the week.
