Yes, it's elevation dependent. On the eastern escarpment down in Marion to Morganton, it will take forever for the cold air to make it over the mountains. They usually only do well in CAD situations.
The system is trending stronger generally. The timing and placement of the front will be kry to where gets snow. East TN and the TN/NC border up to central and eastern VA would be my guess. Places like northern Mississippi and Alabama could get some snow too. The cold air will have trouble reaching areas east of the Blue Ridge.
