Nashville, TN – Temperatures in Nashville will soar into the low 90s with heat index values near 98 degrees through Sunday, pushing outdoor plans and travel into riskier territory as summer’s hottest stretch tightens its grip on Middle Tennessee.
According to the National Weather Service, the extended heat and humidity will last through Sunday evening, with mostly sunny skies and only light southwest winds offering little relief. Overnight lows will only fall to the low 70s, keeping homes and apartments feeling muggy. Local parks, construction zones, and open-air venues should take extra precautions as heat exhaustion risk climbs—especially for outdoor workers, kids at camp, and older adults. Nashville’s biggest roadways, including I-24 and I-65, could see heat-related pavement buckling, while local utilities expect high energy demand.
The chance for relief grows Monday afternoon as a 30 percent chance of showers and thunderstorms develops after 1 p.m., possibly disrupting commutes and outdoor activities into the evening. Spot storms may linger through Tuesday, with a renewed 40 percent chance of rain and thunder both days. Residents should stay hydrated, limit strenuous activity outside during peak afternoon hours, and check in on neighbors—especially as the region’s hottest days align with the final weeks of summer break.
Unsettled weather could continue through midweek, with temperatures remaining in the low 90s and storm chances sticking around. Updates will follow if watches or warnings are issued.
