Heat Advisory in Effect for Southern Middle Tennessee Through Tuesday
Dangerous heat index values could hit 106 degrees across southern middle Tennessee as a multi-day Heat Advisory stretches through Tuesday evening.
NASHVILLE, TENNESSEE — A Heat Advisory issued by the National Weather Service office in Huntsville, Alabama, is in effect for portions of southern middle Tennessee from noon Sunday through 7 p.m. CDT Tuesday, June 30, 2026, with heat index values expected to reach as high as 106 degrees.
The advisory was issued late Saturday night at 11:20 p.m. CDT on June 27 and covers areas across north central, northeast, and northwest Alabama, as well as southern middle Tennessee.
What Residents Should Expect
The combination of high temperatures and elevated humidity is forecast to drive heat index readings to dangerous levels throughout the advisory period. The National Weather Service warns that these conditions may cause heat-related illnesses among residents.
Heat index values, which reflect how hot it feels when humidity is factored in alongside the actual air temperature, can significantly increase the risk of heat exhaustion and heat stroke, particularly for vulnerable populations including the elderly, young children, and those with underlying health conditions.
Affected Areas
The advisory covers a broad multi-state region spanning portions of north central, northeast, and northwest Alabama, as well as southern middle Tennessee. Residents in these areas are encouraged to take precautions during the hottest parts of the day, particularly between noon and early evening when temperatures peak.
According to the National Weather Service, the advisory runs from noon Sunday, June 28, through 7 p.m. CDT on Tuesday, June 30, 2026.
Safety Precautions
Health officials and emergency management agencies advise residents to drink plenty of water, avoid prolonged outdoor activity during peak heat hours, and check on neighbors and family members who may be at greater risk. Air-conditioned spaces such as libraries, community centers, and shopping areas can serve as cooling locations during extreme heat events.
Residents should monitor updates from the National Weather Service and local emergency management offices for any changes to the advisory or additional warnings as conditions develop through the week.
