Nashville, Tennessee – Above-average temperatures are expected across Tennessee from August 5–9, bringing a prolonged stretch of summer heat while precipitation remains close to seasonal averages. Rather than a widespread wet pattern, the Volunteer State is expected to experience scattered showers and thunderstorms typical of early August, with rainfall totals varying significantly from one community to another.
According to the Climate Prediction Center’s 6–10 Day Outlook issued July 30, Tennessee is favored to experience above-normal temperatures, while near-normal precipitation is expected during the outlook period. The climate signal supports persistent warmth and humidity with periodic thunderstorm chances, but no strong indication of widespread excessive rainfall.
Nashville and Memphis are expected to see temperatures rise above early August averages, while communities including Knoxville, Chattanooga, Clarksville, Jackson, Johnson City, and Cookeville could experience isolated to scattered afternoon and evening thunderstorms. Some storms may produce brief heavy downpours, frequent lightning, and gusty winds, though many areas will remain dry between passing systems. Drivers should remain alert for changing conditions along Interstates 24, 40, 65, 75, and 81, where heavier showers could briefly reduce visibility and create ponding on roadways.
The combination of above-average warmth and seasonal rainfall will create muggy conditions across much of the state, especially in the Tennessee Valley and across West Tennessee. Residents planning outdoor activities, hiking in the Great Smoky Mountains, or attending festivals and sporting events should stay hydrated, limit strenuous activity during the hottest part of the afternoon, and monitor local forecasts for developing thunderstorms.
The overall pattern favors continued above-average warmth through August 9, with precipitation remaining near climatological averages across Tennessee. Additional outlooks from the National Weather Service will provide greater detail on the timing and location of individual thunderstorm chances as the period approaches.
