RUTHERFORD CO., Tenn. (WGNS) — Residents of Rutherford County are being urged to prepare for dangerously high temperatures as a prolonged heat wave settles over Middle Tennessee. According to the National Weather Service in Nashville, the region will experience excessive heat beginning Friday, with the most intense conditions expected through mid-to-late next week.

Following morning thunderstorms and humid conditions Thursday, forecasters predict that temperatures will steadily rise into the 90s beginning Friday, with heat index values — or "feels like" temperatures — soaring past 100 degrees. By Saturday and into next week, highs are expected to reach 94–95°F each afternoon, with little overnight relief as lows remain in the low to mid-70s.

The National Weather Service classifies this as a “Major to Extreme Heat Risk”, warning that the prolonged exposure could be dangerous for anyone without adequate cooling, particularly the elderly, young children, and those with preexisting health conditions. The warning also emphasizes the risks for outdoor workers, athletes, and pets.

“These are not just uncomfortable temperatures — they can be dangerous or even deadly if you’re not taking precautions,” meteorologists said in the agency’s latest situation report.

Safety Tips from Local Officials

Emergency management agencies and local health departments are urging residents to:

• Stay hydrated: Drink water regularly, even if you’re not thirsty.

• Avoid peak heat hours: Stay indoors between 10 AM and 6 PM.

• Use fans or air conditioning: Check on elderly neighbors and those without cooling.

• Limit strenuous activity: Exercise early in the morning or late in the evening.

Local cooling centers may be opened if conditions worsen, and schools and outdoor youth programs are being advised to adjust or cancel outdoor activities.

Looking Ahead

The heat wave is expected to persist at least through Wednesday, June 25, with possible thunderstorms late next week offering minimal relief. The National Weather Service is closely monitoring the situation and may issue additional advisories or heat warnings as conditions evolve.
