NASHVILLE, Tenn. – A stretch of September sunshine will send temperatures climbing across Middle Tennessee, raising heat and safety concerns by midweek. Drivers and outdoor workers in Nashville should brace for highs near 90° Wednesday, September 10, with glare on I-40 and other major routes expected during evening commutes.
According to the National Weather Service in Nashville, calm conditions tonight will give way to a warming trend that accelerates Wednesday. Temperatures will top out near 90° by afternoon with light southwest breezes, while overnight lows hold in the mid-60s. This pattern continues with highs near 94° by Friday, keeping roads hot and air quality stressed.
The extended stretch of sunshine brings both relief and risk. Dry weather helps reduce flash flooding threats, but prolonged warmth can strain vulnerable residents, especially children and older adults. Officials advise limiting strenuous outdoor activity during peak afternoon hours, staying hydrated, and never leaving children or pets inside parked vehicles.
Drivers along I-40, I-24, and I-65 should use caution as sun glare increases accident risk, especially during late-day commutes. Road surfaces will remain hot, making tire blowouts and engine overheating more likely for unprepared vehicles.
While skies stay clear through the weekend, the heat peaks early next week with Nashville projected to reach 96° by Monday, September 15. Residents should monitor local advisories as heat-related alerts may be issued if conditions intensify.
