Seriously looking at this possibility we need the NS to slow down in relation to the southern shortwave as right now it is outrunning our southern piece by a solid 12-24 hours. While obviously this would be a major change its not altogether impossible if pieces start moving this way by tomorrow morning. Additionally, our southern shortwave moving further north (which is the trend considering our block failing to form) would help in this process. Another thing to note is a small piece of energy detached from our shortwave out west which seems to help move it push the precip north and constructively interact with the NS. Looking at the recent Euro run (top) vs old run (bottom) this is quite clear to see.
Now that previous discussion was focused on salvaging this into a decent snowstorm. If instead we set our sights on a far more reasonable coating to 1inch storm we just need the Euro as it is to be right. Though, an interesting solution is the NAM. The NAM opts to have no NS interaction and instead brings a stronger southern vort north on its own. While this has the thermals shot (partially due to no cold push I assume) it manages to get a solid quarter inch of ice in the area.
As for now all we can do is see which way the models evolve. Though, it wouldn't surprise me to see this creep north as @Terpeast mentioned with the blocking up north failing to materialize.
