Travel impacts are expected to be high and travel may be dangerous early Sunday morning through early Sunday afternoon.High pressure centered over the Mid-Atlantic region will slowly start to move off the East Coast leaving a shallow layer of sub-freezing air near the surface as our next winter storm approaches from the Great Lakes region tonight.
