Raleigh, N.C. — Temperatures will vary widely from north to south across North Carolina Sunday as a low pressure system and trailing warm front move through the state, WRAL meteorologist Mike Moss said.

Temperatures will struggle to get into the 50s north of the Triangle, but could reach the upper 60s in the southern coastal plain. The one constant will be clouds, as much of the state will go without sunshine on the final day of the weekend.

"We could see scattered sprinkles and showers across our entire viewing area Sunday," Moss said. "We saw some thundershowers move through Wake County this morning, but those have dissipated."

Runners tackling Raleigh's City of Oaks Marathon, half-marathon and 10K races were greeted by temperatures in the low 40s Sunday morning. 

Due to the temperatures difference and a more unstable atmosphere because of the warm front, areas south and east of the Triangle could see thunderstorms during the afternoon and evening hours. 

"The front is going to cut the region in half and really keep the air aloft unstable," Moss said. "It will be tough for any severe weather to develop, but thunderstorms are possible in the southern coastal plain by this afternoon."

Temperatures will dip into the mid-30s overnight before partly cloud conditions and highs in the mid-50s return Monday. On Election Day, much of the area should stay dry, and temperatures will top out about 54 degrees. 

"Areas in the eastern third of the state could see some showers late in the day Tuesday, but it should be dry while polling places are open," Moss said.
