I consider any snowfall of 2" or more during March as major. Both the 00z NAM and GFS are progging snowfall reaching/ exceeding that criteria in far north Georgia, the southern Appalachians, and portions of the Carolinas.I wouldn't consider this upcoming event major (although any time the south gets even a dusting is notable). Unusually warm ground and rather marginal surface temps will likely preclude major accumulations (if any) outside higher elevations.
Now the arctic blast will be unusual but should be short lived (4/5 days).
