Schools cancel classes ahead of second storm

The National Weather Service extended a winter weather advisory for all of central North Carolina until 12 p.m. Wednesday.

Temperatures will retreat into the 20s across central North Carolina overnight, making slick roads a continued concern heading into the Wednesday morning commute.

Wednesday will start with temperatures below freezing, but mid-day highs will reach the low 40s.

Another winter weather system is expected to move into the area Wednesday day.

"We have a chance of seeing rain, snow, or even a wintry mix with this storm," WRAL Chief Meteorologist Greg Fishel said. "There is no guarantee that all of the precipitation will be snow or that the snow will accumulate."

The Triangle could receive 6-8 inches of snow, but that amount depends on how much cold air is in the atmosphere and how warm the surface temperature is, WRAL meteorologist Mike Maze said.

Gov. Pat McCrory said he is prepared to declare a state of emergency as the system move into the state.

“The safety of both motorists and our team members continues to be our top priority as we work to stay ahead of this storm and its impact to travel throughout the state,” said state Transportation Secretary Tony Tata.

The National Weather Service issued a winter storm watch from 6 p.m. Wednesday until 12 p.m. Thursday for much of central North Carolina.

The system is expected to move out Thursday morning, but temperatures will struggle to get above freezing.

Temperatures will remain below normal on Friday, however a warm up is expected early next week.
