Nashville was clear and nearly calm before sunrise Tuesday, with temperatures in the low 70s. By afternoon, the city is expected to reach 99 degrees, with the heat index climbing as high as 108.
Wednesday And Thursday Look Worst
The hottest stretch arrives Wednesday and Thursday, when highs are forecast to reach 101 degrees and heat indexes could hit 110. The latest National Weather Service forecast discussion describes a major to extreme heat risk by midweek, while rain chances remain close to zero.
Winds should stay light, generally calm Tuesday and around 0 to 5 mph from the south Wednesday and Thursday. Overnight lows will offer little relief, hovering around 75 to 77 degrees through Friday morning.
Weekend Brings Small Rain Chance And Slow Relief
Friday remains brutally hot near 100 degrees, but temperatures should ease slightly over the weekend. Saturday’s high is expected to reach 98, followed by 97 Sunday and 95 on Labor Day.
A slight chance of afternoon showers and thunderstorms arrives Saturday and Sunday, with a similar chance of rain showers after 1 p.m. Monday. The forecast calls for only a 20% chance of precipitation during those periods, so any cooling rain may be hit-or-miss rather than a full washout.
Heat Safety Matters Across Nashville
With afternoon heat indexes in the triple digits, residents should limit strenuous outdoor activity during the hottest hours, drink plenty of water and check on older neighbors, children and pets. Never leave people or animals in a parked vehicle, even for a short errand.
Nashville’s Office of Homeless Services lists heat-response support locations and outreach services, including Room in the Inn and Nashville Rescue Mission. The forecast currently lists no watches, warnings or advisories, but conditions are expected to become most dangerous Wednesday and Thursday.
