Nashville, Tennessee – Middle Tennessee residents face a double weather threat today as dangerous heat grips the region through the afternoon before strong thunderstorms develop this evening. Heat index values are expected to climb into the 100 to 110 degree range, creating conditions that can quickly lead to heat-related illness for anyone spending extended time outdoors.
According to the National Weather Service in Nashville, the most dangerous heat will occur between 10 a.m. and 6 p.m., with afternoon high temperatures ranging from 89 to 98 degrees. The combination of heat and humidity will produce widespread major heat impacts, prompting residents to stay hydrated, limit outdoor activities during the hottest part of the day and seek air-conditioned spaces whenever possible.
A second hazard develops this evening as a Level 1 of 5 Marginal Risk for severe thunderstorms extends across areas east of Interstate 65. The strongest storms are expected Tuesday evening and overnight, with damaging wind gusts serving as the primary threat. Locally heavy rainfall could also produce isolated flash flooding, particularly because many locations are already saturated from recent rainfall.
Communities including Nashville, Cookeville, Crossville, Smithville, Jamestown and surrounding portions of the Cumberland Plateau should be prepared for rapidly changing weather conditions after sunset. Strong winds may bring down tree limbs and create isolated power outages, while heavy rain could quickly flood low-lying roads.
Residents should drink plenty of water, check on vulnerable neighbors and never leave children or pets inside parked vehicles. This evening, have multiple ways to receive weather warnings and be prepared to move indoors immediately if severe thunderstorms approach. Additional advisories or warnings may be issued as storms develop later today
