Tennessee Heat Break Expected Starting Sept. 23
Tennessee has been experiencing sweltering heat under an oppressive heat dome, with temperatures remaining above normal throughout September. According to the National Weather Service, a slight break in the heat is expected starting September 23, coinciding with the astronomical start of fall on September 22. Memphis, Nashville, and Knoxville will see daytime highs drop slightly, with Memphis reaching 92°F (33.3°C) on September 22 and Knoxville seeing highs of 83°F (28.3°C) on September 23.
