Tennessee’s Forecast: Sizzling Days, Clear Skies
Published Jul 22, 2025
Tennessee is drying out with only a 20% storm chance over higher terrain through midweek. Highs climb from 92° Tuesday to 95° by Thursday, with heat index values near or above 100°. Nights stay muggy in the 70s. Scattered storm chances increase this weekend, possibly bringing heavy rain and isolated flooding, while next week starts off very hot again.
Hot weather and clear skies forecast
Tennessee residents should expect a prolonged period of hot weather and clear skies. The state is bracing for sizzling days, with temperatures consistently in the high 90s and potentially exceeding 100 degrees Fahrenheit in some areas. Residents need to take precautions to stay safe and comfortable.
Warm, dry air from the Gulf
The weather pattern across Tennessee is dominated by a high-pressure system drawing in warm, dry air from the Gulf of Mexico. This setup causes clear skies and elevated temperatures. While sunshine is good for activities, the heat is a risk, especially for the elderly, children, and those with chronic health conditions.
95 to 102 degrees Fahrenheit expected
In cities like Nashville, Memphis, Knoxville, and Chattanooga, daily high temperatures are expected to range from 95 to 102 degrees Fahrenheit. Humidity will add to the discomfort, making it feel even hotter. The combination of high temperatures and humidity can lead to a heat index surpassing 105 degrees Fahrenheit, increasing the risk of heat-related illnesses.
Lows remaining in the mid-70s
Nighttime temperatures will offer little relief, with lows remaining in the mid-70s. This lack of overnight cooling can exacerbate the effects of the daytime heat, as bodies have less opportunity to recover. Residents are advised to keep their air conditioning running, if possible, and to ensure proper ventilation in their homes.
Wear sunscreen, sunglasses, protective clothing
The clear skies also mean that UV radiation levels will be high. It’s essential to wear sunscreen, sunglasses, and protective clothing when spending time outdoors, even for short periods. The sun’s rays can be particularly damaging during the peak hours of 10 a.m. to 4 p.m.
Hydration, lightweight clothing, limit activities advised
Weather experts recommend several strategies for staying cool and safe during this heat wave. Hydration is key; drinking plenty of water throughout the day is crucial, even before feeling thirsty. Avoid sugary drinks and alcohol, as they can dehydrate the body. Wearing lightweight, light-colored clothing can also help to reflect sunlight and keep the body cooler.
Schedule outdoor work for cooler hours
It’s also important to limit strenuous activities during the hottest parts of the day. If outdoor work or exercise is unavoidable, schedule it for early morning or late evening when temperatures are slightly lower. Take frequent breaks in shaded or air-conditioned spaces to avoid overheating.
Safe, cool environment to escape heat
For those without access to air conditioning, public cooling centers are available in many communities. These centers provide a safe, cool environment where people can escape the heat. Local governments and community organizations often operate these facilities during extreme weather events.
Drought conditions could worsen next week
Looking ahead, the forecast indicates that this hot and dry pattern will persist for at least the next week. There is no significant rainfall expected, which means that drought conditions could worsen in some areas. Farmers and gardeners should take steps to conserve water and protect their crops from the heat.
Navigate sizzling days safely and comfortably
Residents are encouraged to stay informed about the latest weather updates and heed the advice of local authorities. By taking proactive measures, Tennesseans can navigate this period of sizzling days and clear skies safely and comfortably.
Prolonged hot weather poses health risks
In summary, Tennessee is set to experience a prolonged period of hot weather with clear skies. High temperatures, combined with humidity and strong UV radiation, pose a risk to public health. Residents are urged to stay hydrated, limit outdoor activities during peak heat hours, and seek refuge in air-conditioned spaces when possible. Staying informed and taking precautions are essential for managing this heat wave.
