Raleigh, North Carolina – Thunderstorms could disrupt travel and outdoor plans across central North Carolina by mid-afternoon Sunday, as dangerous heat and sudden downpours threaten the Raleigh-Durham region, especially along I-40. Residents should prepare for rapidly changing conditions, with heat index values reaching up to 102°F and a 50% chance of showers and thunderstorms after 2 p.m.
According to the National Weather Service at Raleigh-Durham International Airport (KRDU), Sunday will start mostly sunny before storms develop in the afternoon, bringing the potential for heavy rain, gusty winds, and localized flooding. Motorists traveling I-40 and surrounding roads are urged to monitor radar updates, avoid driving through water-covered roadways, and keep mobile devices charged in case of power outages.
Storm chances remain elevated through Monday and Tuesday, with each afternoon bringing a fresh risk of lightning, sudden downpours, and brief road closures.
