Tennessee Heat Dome to Ease After September 23
• Tennessee has been experiencing sweltering conditions under one of the strongest heat domes in the world, which has been in place since September 16,
• This weather phenomenon, characterized by high humidity, limited cloud cover, and light winds, has caused temperatures to feel even hotter than recorded. According to NASA, heat domes trap heat by allowing sunlight to reach the ground unabated. While meteorological fall began on September 1, the astronomical fall, starting on September 22, is expected to bring some relief. Temperatures across the state are forecast to gradually cool, with Knoxville, Memphis, and Nashville seeing slight drops in highs starting September
Impact & Risks
The oppressive heat has affected the entire state of Tennessee, with cities like Memphis experiencing highs in the upper 90s and Nashville and Knoxville seeing temperatures in the mid-80s. The prolonged heat poses risks such as heat-related illnesses, especially for vulnerable populations like the elderly and those with pre-existing health conditions. While a slight break in the heat is expected around September 23, above-average temperatures will persist through the end of the month, delaying the arrival of true fall weather.
