Memphis, Tenn. – Relentless summer heat is back in full force across Tennessee Monday, July 21, with Memphis heading toward dangerous 100-degree highs and a blistering 110° heat index.
According to the National Weather Service, a Heat Advisory remains in effect from 11 a.m. to 8 p.m. CDT Monday, warning residents of extreme conditions that could lead to heat exhaustion or stroke without proper precautions. Southwest winds will offer little relief as the humidity pushes real-feel temps deep into the danger zone.
Daytime highs in Memphis will reach 98°F Monday, followed by 99°F Tuesday and a scorching 100°F on Wednesday, making it one of the hottest stretches of the summer so far. Travelers along I-40 and I-55 should stay alert for heat-related vehicle issues and never leave pets or children in parked cars.
Those spending time outdoors — especially workers, athletes, and the elderly — should limit exertion between noon and 6 p.m., stay hydrated, and take breaks in shaded or air-conditioned areas.
Looking ahead, the heat will persist through Thursday, with only a slight break expected by Friday, when a 20% chance of isolated thunderstorms could offer brief relief.
