Early Sunday, temperatures ranged from the low 20s to freezing across central North Carolina. That chill allowed any moisture left on the roads to freeze into black ice.
"The problem with black ice is that sometimes you can't see it until you're on it. It looks like it's just wet, but it's really ice," WRAL meteorologist Nathan Johnson said.
A car ran off the road due to black ice at Interstate 85 and U.S. Highway 70 in Durham, police said. The driver had a broken leg.
In Person County, where nearly 7 inches of snow fell Friday, black ice formed overnight, but people were staying off the roads Sunday morning. Deputies said they responded to a few wrecks before midnight.
Whatever ice was on the roads was quickly melted away by the sun.
"Things are brightening up a bit," WRAL meteorologist Mike Moss said. "We should see more sunshine than clouds as we kick off the week."
Sunday will see a high around 40 degrees, and temperatures dip back into the mid-20s overnight.
"We'll see a little bit of a warming trend tomorrow (Monday), though it will stay on the cool side of normal," Moss said.
Monday will be mostly sunny, with a high in the upper 40s.
