North Carolina – Darkening clouds are beginning to build over central North Carolina late Monday morning, and today’s warm, humid air is fueling another active round of thunderstorms. While breaks of sunshine will push temperatures close to 89 degrees this afternoon, meteorologists are watching for storms capable of producing damaging wind gusts, torrential downpours, and localized flooding before the day is over.
According to the National Weather Service in Raleigh, thunderstorms are expected to develop this afternoon after earlier showers, with rain chances increasing to 80%. A Hazardous Weather Outlook highlights a Level 2 out of 5 severe thunderstorm risk, with damaging straight-line winds identified as the primary threat. The agency also notes that repeated rounds of heavy rain from Monday through Wednesday could produce isolated flash flooding in poor drainage and low-lying areas. Spotter activation may be needed if stronger storms develop.
Motorists should prepare for rapidly changing conditions along I-40, I-440, I-540, US-1, and US-64 during the afternoon and evening commute. Heavy rain may reduce visibility, while brief ponding on roads could slow traffic. Travelers using Raleigh-Durham International Airport (RDU) should also monitor airline updates for possible delays if thunderstorms move across the terminal area.
Tuesday brings a different concern before storms return. High temperatures are expected to reach 94 degrees, with heat index values climbing as high as 102 degrees during the afternoon. The combination of heat and humidity will increase the risk of heat-related illness for anyone spending extended time outdoors. Stay hydrated, limit strenuous activity during peak heating, and check on vulnerable neighbors.
Storm chances continue Tuesday night before becoming widespread again Wednesday. Rain probabilities increase to 90%, with additional thunderstorms capable of producing heavy rainfall and gusty winds. While widespread tornadoes are not expected, an isolated brief tornado cannot be completely ruled out in stronger rotating thunderstorms and should continue to be monitored.
The weather finally begins to ease Thursday as temperatures settle into the lower 80s, although scattered showers remain possible before drier conditions gradually return.
Long-range outlooks continue favoring above-normal temperatures later next week, suggesting summer heat quickly rebounds after this active stretch.
If you’re traveling across the Triangle today or Tuesday, build extra time into your plans and keep an eye on changing radar trends. Are storms already developing where you are?
