Nashville is waking up to clear skies Monday, but the forecast is already flashing a much bigger problem than a little summer sweat: highs near 97°F and heat-index readings up to 109°F. The oppressive stretch is expected to continue through the weekend, with only a few late-day storm chances offering relief.
Monday Starts Sunny, Then Feels Like 109
The latest observation from Nashville International Airport found clear skies and a temperature around 72°F before daybreak. Monday will turn mostly sunny, with southwest winds at 5 to 10 mph and a high near 97°F; the heat index could reach 109°F, according to the National Weather Service in Nashville.
Tonight stays mostly clear, but it will not cool much: the low is expected to hover around 76°F, with the evening heat index still as high as 103°F. No watches or warnings are active in the provided forecast, though forecasters say the week’s heat risk could reach the major level, with heat advisories possible west of the Cumberland Plateau, especially Tuesday and Wednesday.
Storm Chances Return Tuesday And Wednesday
Tuesday will be another 97-degree day, with a 20% chance of showers and thunderstorms after 5 p.m. Wednesday brings the best rain odds of the near-term forecast, with a 40% chance of afternoon and evening showers and storms.
Those storms may be hit-or-miss, but any downpour could be intense. Heavy rain and localized flash flooding are the main concerns, while gusty winds are possible but the threat of severe winds remains low.
Weekend Heat Could Peak Near 99
The heat settles in Thursday through Sunday, when highs are forecast between 98°F and 99°F. Friday and Saturday each carry only a 20% chance of a late-day storm, while Sunday is expected to be sunny; overnight lows stay in the mid-70s.
What Nashville Residents Should Know
For anyone working or exercising outside, the most dangerous window will be the afternoon, when temperatures and humidity combine to push the feels-like temperature well above the actual reading. Take frequent breaks in air conditioning or shade, drink water before you feel thirsty, and check on older neighbors, young children, pets and anyone without reliable air conditioning.
Nashville’s city heat-response page lists cooling and hydration support during activated heat responses, including water distribution, cool rides and air-conditioned public library locations. The Metro Action Commission also says eligible older adults, families with children under 6 and residents with qualifying disabilities can seek free fans or air-conditioning units through Aug. 31; details are available from Metro Action and the city’s heat-response program.
