Raleigh started Sunday under steamy, partly cloudy skies with temperatures already in the upper 70s and humidity to match. By afternoon, the heat is expected to crank into the mid 90s, with humidity pushing the heat index to a brutal 105 to 107°F. A Heat Advisory is in effect late this morning through this evening, and forecasters expect scattered storms, some on the strong side, to fire up late in the day and into the night.
Heat Advisory Today
The National Weather Service in Raleigh has issued a Heat Advisory for Sunday, July 19, 2026, from 11 AM to 8 PM, warning that heat index values could reach around 106 to 107°F. Highs should top out near 95°F with dew points in the 70s, which means even brief periods outside can lead to heat stress if you are not careful. Full advisory details and the latest forecast are available from NWS Raleigh.
Storms Late Sunday Into Monday Morning
Scattered showers and thunderstorms are possible by late afternoon, with coverage building through the evening and overnight. The wettest stretch looks to be Sunday night, when some spots could see one half to three quarters of an inch of rain. Any stronger storm may pack damaging wind gusts. Drivers heading out this evening should be ready for sudden downpours, ponding on roads, and quick drops in visibility during heavier cells.
How To Stay Safe
If you do not have reliable air conditioning, Wake County and the city encourage residents to use public cooling options and libraries; you can find locations and hours through the City of Raleigh. Drink plenty of water, steer clear of heavy outdoor work during the advisory hours, and shift necessary yard work or exercise to early morning or later evening. Take a moment to check on neighbors, older relatives, and pets.
Short-Term Outlook
The muggy, unsettled pattern sticks around into Monday and through midweek. Monday, July 20, is expected to be a bit cooler, with a high near 89°F, but showers and storms are still likely. By Tuesday and Wednesday, highs should rebound into the low 90s with more chances for thunderstorms. Keep phones set to receive weather alerts and check updated forecasts before locking in any outdoor plans.
