The LAST CALL map only features some minor changes from the previous forecast map. I have replaced the 5 to 8 inch snow band with the 4-6 inch snow band and I have shifted it to the South because most of the data on this Saturday morning and midday shows has trended this way. There is a clear shift southward of the 1 inch in snowline in West Virginia , central Pennsylvania , and eastern New York State. In addition. the high-resolution short-range models have shifted the heaviest snow band to the south of the big cities of I-95. This results in an increase in the snow amounts in the Northern Neck, southern Maryland. and across the central Delmarva into southern New Jersey.
The forecast uncertainty is the Richmond Metro area but the latest and final model runs of the 18z NAM have shown an increase of up to 3.5 inches of snow in the Richmond Metro area. The last two previous 3KM NAM model runs actually showed all rain and no snow of any kind in the Richmond Metro area.
From what I can see the best snows will be in a range from Roanoke to Lynchburg Charlottesville up into Fredericksburg Tappahannock Lake Anna then into the southern Maryland counties of st. Mary's and Calvert, and into the far Southern New Jersey and far Southeastern Massachusetts. Temperatures will be cold enough in Southwest Virginia as well as the central Virginia and Piedmont regions to support moderate to heavy snowfall early Sunday morning.
Also be advised that there is a potential for significant ice storm in much of central and western Virginia , much of Maryland, into Southeast Pennsylvania, and the eastern panhandle of West Virginia on Thursday February 11th. More on this later
