Black ice a threat again Saturday morning

The storm system that brought wintry weather to the Triangle Thursday caused problems during the morning commute Friday as temperatures hovered near freezing, and the scenario could repeat again to start the weekend, according to the National Weather Service.

The National Weather Service issued a winter weather advisory for several central North Carolina counties, including Wake, Durham, Person, Orange, Granville and Franklin counties from 9 p.m. Friday through 10 a.m. Saturday due to potentially hazardous driving conditions.

Highs Saturday will struggle to reach the upper 30s under variably cloudy skies.

"This cold air that is headed our way again is going to be with us through the weekend, and it's going to mean that moisture still on the roads will refreeze each night," WRAL meteorologist Elizabeth Gardner said. "It could be next week before road conditions are perfectly fine in the mornings."

Partly to mostly cloudy conditions will close out the weekend on Sunday as highs push to near 40 degrees, and rain arrives Monday.

"Monday and Tuesday we start to see a little bit of a warmup. On Wednesday, the real warm air starts to surge across North Carolina. We could end up in the 60s on Wednesday and Thursday, but we do have rain in the forecast."

If temperatures do return to the 60s next week, it will be the first time they will have climbed that high since Feb. 9. The Triangle saw a three-day warm spell from Feb. 7-9, when highs were in the 60s and even 70s on one day.
