Tuesday, June 9, 2026, started off thick and soupy in Memphis, with a muggy, partly cloudy morning and temperatures hovering near 776F before most people finished their first cup of coffee. It will only get more punishing from there. The National Weather Service has a Heat Advisory in effect from 11 a.m. to 8 p.m. Tuesday, warning that heat-index values could climb as high as 1096F.
Afternoon Heat And Humidity
By this afternoon, forecasters expect highs near 946F, with south-southwest winds around 10 mph and only a slight chance of rain to cut the steam. With dew points stuck in the mid-70s, heat-index readings are projected to jump into the 105 to 1096F range, raising the risk of heat-related illness for anyone working, playing, or otherwise stuck outside. Those details come from the National Weather Service Memphis.
Through The Week
The brutal combo of heat and humidity is expected to hang around through Thursday, with highs in the mid-90s and sticky overnight lows in the mid-70s that will not offer much relief. A front is forecast to move in Friday, boosting the odds of showers and thunderstorms and likely knocking the worst of the heat back by the weekend.

Heat Safety
Residents are urged to drink plenty of water, avoid heavy exertion during the late morning and afternoon, and use air-conditioned spaces when possible. Never leave children or pets unattended in vehicles, even for a short time. If you or someone around you starts to show signs of heat exhaustion or heat stroke, such as confusion, rapid heartbeat, or fainting, call 911 or head to an emergency room immediately. If you do not have reliable cooling at home, consider community options and check local resources for available locations and hours.
