Nashville is starting Friday under clear skies, but the calm morning will give way to another dangerous round of heat. Temperatures were near 78 degrees early Friday, with humidity already making the air feel muggy across the city.
Friday’s high is expected to reach 100 degrees, with heat index values climbing to around 111. A Heat Advisory remains in effect through 8 p.m. Saturday, a significant escalation from Thursday’s forecast, when the advisory outlook was less severe.
Afternoon Storms Stay Spotty
Most of Friday will be sunny, but a slight chance of showers and thunderstorms arrives between 1 and 5 p.m. Rain chances remain around 20%, though any storm that develops could bring a quick downpour and gusty winds.
Saturday will be sunny and nearly as hot, with a high near 99 and heat index values again reaching roughly 111. Forecasters are also watching for a better chance of afternoon and evening storms Saturday, including isolated stronger wind gusts.
Some Relief Arrives Sunday
The heat eases slightly Sunday, when Nashville should reach about 97 degrees under sunny skies. Labor Day is expected to be sunny with a high near 95, followed by a noticeably cooler overnight low around 71.
That break will be brief rather than dramatic. Highs are expected to stay near 95 Tuesday and rise back toward 97 Wednesday and Thursday, with only limited chances for afternoon rain through much of next week.
Heat Advisory Calls For Extra Caution
The National Weather Service advises residents to drink plenty of fluids, stay in air conditioning when possible and avoid prolonged time in direct sun. People working outdoors should take frequent breaks in shaded or cooled areas, and neighbors should check on older adults and anyone especially vulnerable to heat illness.
Anyone showing signs of heat stroke should be moved to a cool, shaded location and treated as an emergency by calling 911.
