Interesting snippet from their afternoon AFD-
As far as the storm, It is currently located near Arkansas with banded F-Gen driven heavy snow located north and east of its center towards the midwestern states. In terms of overall trends in the forecast as far as how it will affect the mid Atlantic, there continue to be some differences in our forecast guidance regarding the exact track and evolution of system. Generally speaking, global guidance weakens the banding a lot more as it approaches the area and has heavier precip amounts farther south compared to the Hi-res guidance. Our forecast leans more towards the higher QPF of the hi-res guidance but has it shifted slightly south a little more towards the Global guidance. This is based on overall trends and reports from how the system is evolving upstream.
