Good luck with trying to get the first disturbance to trend back south, lol, confidence is starting to increase that it'll end up in the OH valley and lower great Lakes as usual for a NINA, and of course as I mentioned earlier wrt the northern tier snow cover extent, the track of that system now makes more sense, and could potentially help open the door for us down the road if things line up... Even those along the mid-Atlantic I-95 corridor should be weary to hang your hat on the current GEFS/EPS solutions wrt seeing wintry precipitation, they're still in the process of adjusting from the wave taking its sweet time to come out of the west. I think for now only the south-central plains, OH Valley, lower lakes, interior northeast & maybe north-central coastal New England are in relatively decent shape to receive wintry weather from the first system. Although the slowing of the overall trough allots more time for the arctic front to make headway southeastward, the PV lobe over southeastern Canada that was shearing the system apart and suppressing it southward east of the Rockies, now has time to get out of the way, hence the first system now has time to amplify, thus the massive shift northward. There's definitely at least an outside chance of a secondary wave riding along the front, but we need to give this another few days before we start getting excited about a storm... This secondary disturbance still may not form and could consolidate with the first initial piece and lead to a massive storm that goes into the lower lakes, providing us with perhaps maybe some very light, parting wintry wx as the cold air would be chasing whatever moisture remains along the front as the EPS currently shows. Although this isn't the favored solution atm, it's a very legitimate one...
