Winter Weather Alert - SNOW and MIX

What has been an absolutely wild system will go through changes the next 24 hours and will leave some with very little snow due to the way that this system will evolve.

SOUTHERN REGIONS:
Already seeing snow break out of the North Carolina and South Carolina Piedmont. Areas of the mountains and immediate Piedmont will see 4 to 8" of snow and some ice, but that will not be more than about .1 to .15 of an inch. Warmer air will influence areas of the Piedmont itself and after 2 to 4 inches of snow, sleet and then freezing rain will be in the offing and ice will accumulate to nearly .25 to as much as .5" in some spots. This is true for North Carolina and South Carolina!
Of note, the total snow amounts for the mountains could approach 10 to 12"

Middle Atlantic - VA, Bordering NC counties of VA
Snow will break out later today in the southern part of the region. Areas in the Mountains will see 3 to 6" of snow and some sleet is possible. Snow in areas east, but a general 2-3 inches will fall as this region will not get the heavier precipitation that areas south will see. VA itself will be an area of lighter accumulations. The Piedmont will see 1 to 3 inches. Areas along and east of I -95 through Fredericksburg and down to the NC/VA border will likely see ice as well, but not a large amount. Snow in the western part of the Piedmont north of a Richmond to Roanoke line will likely only see 1 to 2 inch snow amounts. That will carry all the way up to the Piedmont of Maryland as well. From Fredericksburg north to DC along I-95 and 20 miles either side a more solid 2 to 3 inches of snow seems likely. Then North of DC and eastern counties will see a slight bit higher possible with 2 to 4" likely and some seeing closer to 5" as you approach Baltimore.
The coastal plains, from the coast to about 40 miles inland will see 1 - 2" of snow and then a mix and even rain.

North regions. East PA, NJ, DE
A more substantial 4 to 8 inches looks likely with some mixing issues along the coast. Even further north, up toward northern NJ 6 to 10 " totals look likely and 12"+ amounts not totally far fetched.

May be all the time I have for this today. NC, SC situation is on its way - late this evening I will update the VA and Northward thoughts.
