Raleigh woke up sticky on Tuesday, July 21, 2026, and will roast into the afternoon with a high near 94°F and a heat index approaching 103°F. Southwest winds will pick up to about 8–13 mph with gusts near 25 mph, so outdoor activity will feel hotter than readings suggest. Expect humid conditions through the evening with only spotty, short-lived relief overnight.
The National Weather Service has issued a Heat Advisory for parts of the southern Coastal Plain, including Cumberland, Hoke, Sampson, Scotland and Wayne counties, from noon to 7 p.m. Wake County is not included, but forecasters still warn of several hours of oppressive heat across the Triangle. A frontal system approaches later this week and will increase storm chances, so today’s blast of heat may be brief before waves of showers and thunderstorms arrive. Limit heavy outdoor exertion during peak heat hours and keep kids, pets and older neighbors hydrated and shaded. For the full forecast and hazard details, see the National Weather Service.
Evening And Midweek Thunderstorm Threat
There is only a slight chance of showers and thunderstorms this evening (Tuesday, July 21, 2026) after about 7 p.m., but coverage climbs Wednesday, July 22, 2026, and Wednesday night. Meteorologists say storms Wednesday afternoon could produce brief downpours of a quarter to a half inch, with training storms overnight that may drop 1–2 inches in some spots, enough to cause localized ponding or brief flash flooding. Keep phones set to receive watches or warnings and be ready to move events indoors if storms form. The National Weather Service is tracking the timing closely.
How To Stay Safe And Cool
Move strenuous activity to early morning or late evening, drink plenty of water, and check on older neighbors and pets during the hot hours. If your air conditioning is unreliable, Wake County and the City of Raleigh list cooling centers and air conditioned public spaces. See the City of Raleigh for local options and hours. We covered the heat and cooling center options in our July 19 story, and we will update if watches or alerts are issued.
Looking Ahead
A cold front is expected to move across North Carolina on Thursday, July 23, 2026, and then stall across the Carolinas into the weekend, bringing a cooler, more unsettled pattern with below normal highs and periodic showers. Placement of that front will determine exactly who sees the heaviest rain, so totals will vary across the Triangle. Check updated forecasts before weekend plans. We will keep tracking any watches or advisories through the week.
