Friday, May 15, 2026 - clear and cool in Raleigh to start the day. RDU (Raleigh–Durham International Airport) checked in at about 46°F at 5:35 a.m. EDT, a crisp wake-up before things start to heat up. Expect sunshine today with a high near 77°F and light northwest winds around 7 mph.
Warm Weekend, Hot Midweek
Saturday, May 16 is set to jump into the mid-80s, with afternoon highs around 86°F. From Sunday, May 17 through Wednesday, May 20, the heat really moves in, with forecast highs in the low 90s: near 92°F on Sunday and about 93°F on both Monday and Wednesday.
The National Weather Service points to a ridge of high pressure and warm southwest flow as the culprits, keeping afternoons hot and humid. Heat index values should run close to the actual air temperature, so what you see on the thermometer is pretty much what you get. Forecasters note a slight chance of afternoon showers or thunderstorms late Wednesday, with storm chances increasing on Thursday. No watches or warnings are in effect right now, according to the National Weather Service.
Plan For The Heat
With several days near or above 90°F in the forecast, it is a good time to switch into summer mode: move strenuous activity to the mornings, keep water handy, and check on older neighbors and pets. Wake County continues to run the Cool for Wake fan-and-AC assistance program, and the city keeps a lineup of heat-safety tips and local resources online. For details and local guidance, head to the City of Raleigh. If you are planning outdoor events this weekend, consider earlier start times or indoor backups for the hottest part of the afternoon.
Quick Take
Look for sunny, pleasant weather today with a high near 77°F and a low near 54°F tonight, then a sharp warm-up over the weekend as highs jump into the 80s and low 90s. Keep an eye on the forecast for late-week thunderstorm timing and for any advisories that might develop as the heat sticks around.
