This morning an area of low pressure was beginning to develop of the Coast of Brownsville, TX producing clouds and rain across a good bit of the Texas Gulf Coast. At the same time, cold air is spilling into the eastern United States. As this low strengthens and moves northeast, a major snowstorm is set for the Mid Atlantic and Appalachians.
Right now it appears our area of low pressure off the Texas Coast will explode into a very strong low pressure near the Outer Banks of North Carolina Saturday morning. This will cause near blizzard conditions from parts of North Carolina through the Piedmont of Virginia. Widespread snowfall amounts of over 6” can be expected in these areas with isolated amounts over one foot possible. The snowfall forecast from the 12Z NAM today shows a wide area of over 18” from the mountain of North Carolina to Central Virginia.
