Memphis is staring down a brutal afternoon of summer heat. After waking up to clear skies and roughly 82°F early Tuesday, July 21, with humidity already making it feel thick and uncomfortable, the city is headed for a high near 99°F and punishing humidity that will push the feel-like temps far higher through the afternoon and early evening. Officials are urging residents to ease off outdoor exertion during the hottest hours and to keep an eye on vulnerable neighbors.
Afternoon Heat And Health Risks
According to NWS Memphis, an Extreme Heat Warning is in effect through 9 p.m. CDT Tuesday, July 21, with heat index values expected to climb as high as 116°F and widespread feels-like temperatures above 105°F. Forecasters expect the worst of it from early through late afternoon. People without air conditioning, older adults, young children, and pets face the greatest danger and should stay in cool spaces and drink plenty of water.
Tonight's Storm Threat
A cold front moving in late Tuesday afternoon into the evening will boost the chance of showers and thunderstorms, with the main window for organized storms running from late afternoon through midnight. The primary severe concern is damaging wind gusts. Any storms that do pop up could bring brief heavy downpours, so keep an eye on sky-side conditions if you plan to be outside.
Where To Cool Off
As previously used as an emergency cooling center, the Hospitality Hub at 590 Washington Ave has been activated during recent heat waves and has coordinated free MATA rides to the site in the past. If you need an air-conditioned refuge, call ahead or check local updates for hours and transport options before heading over.
How To Stay Safe
Limit outdoor activity roughly between 11 a.m. and 7 p.m., sip water often, and avoid heavy work or exercise during those peak hours. If someone shows signs of heat exhaustion or heat stroke, such as fainting, confusion, very high body temperature, or not sweating, move them to a cool place, try to cool them with wet cloths or fans if possible, and call 911 immediately.
