CHAPEL HILL – A winter weather advisory remains in effect for the Triangle until 9:00 a.m. Wednesday, as frigid overnight temperatures will result in continued treacherous conditions.

“Any moisture that’s left on the roads does have the potential to freeze overnight,” says National Weather Service meteorologist Ryan Ellis. Only about an inch of snow is expected to fall, but “the real dangerous part, I think, is the patchy black ice overnight.”

That ice has the potential to cause roads to be slick into the Wednesday morning rush hour. Chapel Hill-Carrboro City Schools, Orange County Schools, and Chatham County Schools have already announced they’ll be operating on a two-hour delay Wednesday morning.

Skies will be clear for the rest of the week, but Ellis says cold temperatures will linger – with highs only in the 20s on Wednesday and overnight lows in the teens every night until Sunday.

“The cold weather is the real dangerous thing here,” Ellis says. “As we get this prolonged cold, some of the things to look out for are pipes freezing – we’re telling people to take care of their pets (too)…

“And this event should extend even longer (than the last cold snap), so it’s the duration of the cold that’s the problem.”
