You have the blocking that will be present over Greenland. This current storm slows as it encounters the blocking and that lobe of vorticity has nowhere to go but South and pivot around the exiting low, over the Northeast
If it's further W, it may be able to draw that storm a bit closer along the coast line. There may also be some OES/OER associate with any troughing between the 2 if they remain as modeled.
You want the ULL over New England either gone of further N and W if you're looking for a storm here. All that's going to currently do is suppress the storm that's coming up the coast.
I think it’s just bad timing. That lead s/w pulls the entire system offshore and the ULL is attempting to re-organzine it along the south coast but does it too late. WCB snows look great then go poof as storm attempts to redevelop.
