High pressure will settle into the region Tuesday with plenty of sunshine as a cold front moves in. The front will bring a reinforcing shot of cold air to NC through midweek. 

With cold air in place this could set the stage for some wintry precip by late-week. It all depends how close an area of low pressure gets to us from the south. 

Then even colder air is coming our way for the weekend with well below average temps in the sub-freezing range for days.
