This will now likely be an impactful storm system region wide featuring mod-hvy snow, coastal flooding & power outages w/the highest impacts still focused on the N-Mid-Atl, LI into extreme SNE, with room for this axis to adjust further NW. There are two primary reasons for this:

1) Moving up in time on NWP, the Pacific ULL has remained robust & has retrograded=Constructively interfering & engendering a notably amplified W-US Ridge. 2) Today's departing NE storm is moving out quicker, giving room for significant EC height rises. (increased wave spacing)
