Possible Christmas Day East Coast Storm?

So this is what it looks like right now, We are going to have a Low pressure system drop in from The Pacific Northwest and as it progresses it will eventually gain strength and tap into Gulf of Mexico moisture and then head up into the Great lakes. As it tracks up towards the Great lakes it spawns another low pressure system. That low pressure system will them track up the coast inland and creating havoc with possible Snow, Ice and Heavy rain. Cold air damming, I believe will have a big factor in this storm, mainly because high temperatures will only be in the middle 30's to lower 40's. So if the CAD can stay in place, I think there will be places that can possibly pick up significant snow and/or Ice.
