Temperatures dropped into the teens across the Piedmont overnight, freezing yesterday's rain and snowfall. Now roadways are covered with black ice.

Gail Hartfield is a meteorologist with the National Weather Service in Raleigh. She says temperatures will be in the 20s all morning and won't warm to freezing or above until lunchtime.

“Just encouraging people to take it easy this morning,” Hartfield said. “If you can postpone travel until after noon, that's great and better. You'll see road conditions much improved over what they'll be this morning.”

While the state transportation department is already out salting roads, utility companies are closely monitoring the weather forecast today.

National Weather Service Meteorologist Ryan Ellis said light snow is likely this afternoon, getting heavy tomorrow into Thursday. By tomorrow afternoon, he said, ice will coat much of the state.

Jane Pritchard is a spokeswoman for the North Carolina Association of Electric Cooperatives. She said it would take a heavy snowfall to mess with power lines, but just a half-inch of ice can do a lot of damage.

Winter weather has made for treacherous roadways in the Piedmont over the last couple of nights.

Barrett Smith is a meteorologist with the National Weather Service office in Raleigh. He says freezing rain is responsible for a number of traffic accidents in Chapel Hill and the Northern Triangle.

Smith says that freezing rain occurs when the air on the ground is colder than the air in the clouds.
