Nashville, TN – A high-impact summer weekend is taking shape across Middle Tennessee as blistering heat and scattered afternoon storms target the region Saturday. With heat index values soaring to 109°F and storms possible after 3 p.m., residents and I-40 drivers should brace for reduced visibility, slippery roads, and localized flooding.
According to the National Weather Service in Nashville, a 30% chance of showers and thunderstorms develops Saturday afternoon, following mostly sunny skies and a high near 96°F. Winds will remain light out of the southwest, but the intense heat and humidity will drive instability across Davidson County and surrounding areas. Storms may bring brief downpours and lightning, particularly after 4 p.m.
On Sunday, rain chances increase sharply to 60%, with thunderstorms likely between 1 p.m. and 6 p.m. West-southwest winds will persist as the heat eases slightly to 95°F, but muggy air remains in place. Patchy fog and thunderstorm remnants are possible both Sunday and Monday nights, with overnight lows staying in the low 70s.
By Monday, expect a 40% chance of thunderstorms after 1 p.m., with highs reaching 93°F under partly sunny skies. Patchy morning fog may limit visibility for commuters, especially before 8 a.m.
⚠️ Travel Tip: Drivers on I-24 and I-65 should plan around storm windows and remain weather-aware through the weekend.
