North Carolina – Warm air is surging across the Triangle, and you can feel it in the light breeze and dry pavement heating up fast by midday. Temperatures are pushing into the low 80s, setting up a sharp shift toward wetter, storm-prone conditions by late weekend.

According to the National Weather Service, Raleigh will reach near 82°F with only a slight 20% chance of brief rain into the afternoon. Skies remain mostly sunny, but increasing clouds tonight signal moisture building ahead of a stronger system.

Across Raleigh, Durham, and Cary, roads like I-440, I-40, and US-1 stay dry through Saturday, with highs climbing to 84°F under mostly sunny skies. That warmth may feel like an early summer preview, but it also fuels instability heading into Sunday.

By Sunday after 2 p.m., showers and thunderstorms develop quickly, with rain chances jumping to 90%. Storms may bring bursts of heavy rain, reducing visibility and slowing traffic along I-40 and I-540. Some areas could see brief downpours strong enough to pond water on roadways. Plan extra travel time and avoid flooded streets.

Rain continues into Sunday night before tapering early Monday. Cooler air follows, dropping highs to around 68°F with clearing skies. Looking ahead, temperatures dip further into the low 60s by midweek, with early morning readings near 39°F raising the risk for patchy frost across central North Carolina .
