Memphis woke up to clear skies and calm air early Tuesday, June 16, 2026, with temperatures in the mid 60s at Memphis International Airport. The comfortable start will not last long; the city is on track for plenty of sun and a high near 87°F this afternoon.
What To Expect This Week
Tuesday stays mostly textbook summer: sunny this afternoon with light south winds and a high near 87°F, followed by a mostly clear night with a low near 69°F.
By Wednesday, June 17, the heat really settles in. Temperatures climb to a high near 91°F, and the heat index could push as high as about 101°F in the afternoon. At the same time, a developing system in the northwestern Gulf may start feeding deep tropical moisture toward the Mid-South by Thursday and Friday. That raises the odds of heavy downpours and localized flooding, and it could send showers and thunderstorms right over Juneteenth events on Friday morning. Highs Friday look closer to the mid 80s, according to the National Weather Service Memphis office.
Wednesday Heat And Gusty Winds
Wednesday brings the kind of heat that sneaks up on you. Stronger June sun paired with higher humidity will make the afternoon feel downright oppressive, especially if you are working or playing outside. Hydrate, take breaks, and do not wait until you feel overheated to slow down.
South-southwest winds are expected around 5 to 15 mph with gusts up to 30 mph, enough to shove around unsecured tents and canopies and make cycling or driving lighter vehicles a bit of a hassle. If you are setting up outdoor gear, stake it down, and consider more shaded or indoor plans during the late afternoon peak.
Tropical System To Watch
The National Hurricane Center is giving a roughly 50% chance of tropical cyclone formation in the northwestern Gulf over the next few days, and operational models currently nudge the system toward the Lower Mississippi Valley from Thursday into Friday. If that track holds, pockets of two to four inches of rain are possible across parts of northeast Mississippi and nearby Mid-South counties, and a Flood Watch may be required later this week, per the National Weather Service Memphis office.
Plan Ahead
Event organizers should have a wet-weather backup plan ready for Friday and make sure tents, stages, and signage are properly secured ahead of Wednesday’s gustier winds. For everyone else: keep water handy during the afternoon heat, avoid low-lying roads if heavy rain starts to fall, and follow guidance from local officials if Flood Watches or warnings are issued. This story will be updated if any watches or warnings are posted.
