Memphis started Tuesday, June 30, 2026, already feeling muggy, with clear skies and about 77°F at Memphis International Airport this morning. Forecasters say that was the easy part. The real heat is set to slam the city this afternoon, with highs near 97°F, a heat index that could top 110°F, and only slight relief after sunset.
Afternoon Heat and Humidity
Sunshine will drive temperatures into the mid-to-upper 90s this afternoon, with the official forecast calling for a high near 97°F and heat-index values up to 110°F. According to NWS Memphis, light winds will hang around while humidity keeps conditions oppressive right into the evening hours.
Dangerous Midweek Heat
An Extreme Heat Watch is in effect from Wednesday morning through Thursday evening, and Wednesday’s high is forecast near 99°F with heat-index readings that may reach 114°F. The NWS warns that the risk of heat-related illnesses will climb and advises residents to "Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors." In other words, treat this heat like a serious health threat, not just an inconvenience.
Where To Cool Off
The city and local charities are rolling out cooling options for anyone who needs a break from the brutal temperatures. The Hospitality Hub in downtown Memphis serves as the city's designated warming and cooling center and opens during dangerous heat events. Check the Hospitality Hub for hours and services, and see Memphis turns into a pressure cooker for background.
Heat Safety Tips
Limit strenuous outdoor activity between late morning and early evening, drink water frequently, and head for air-conditioned public spaces if you do not have cooling at home. Never leave children or pets in a parked car, even for a short time, and check on older neighbors or anyone with health conditions. If someone shows signs of heat exhaustion or heat stroke, such as dizziness, confusion, fainting, or a very high body temperature, call 911 immediately.
Tonight And The Weekend
Overnight will not bring much of a cooldown, with lows holding in the mid-to-upper 70s, and the dry, hot pattern is expected to stick around into the holiday weekend. Only isolated thunderstorms are possible late Wednesday into Thursday. Stay tuned to local forecasts and official updates; according to NWS Memphis, this intense heat pattern could persist through Thursday.
