Freezing Rain and Snow Continue across the Mid Atlantic on Monday
The area of low pressure that brought significant winter weather to the region over the weekend has moved offshore. However, some moisture lingers over the Mid Atlantic, which continues to bring snow and freezing rain to the region. As temperatures rise, most of the precipitation should transition to rain before tapering off this afternoon. An additional inch or two of snowfall and a trace of ice is forecast across the Carolinas and Virginia before moving out of the region.
