Banding according to GFS is gonna be closer to the rain/snow line with temps at or below freezing... maybe we hit higher ratios. But i don't think really ANY model knows where the banding sets up, at this point.
I don't expect much more than 15:1 ratios at the highest, if another deathband is also present in the cooler temps closer to N MD... if temps remain in the 20s.
In NJ/DE,S/SE PA, ratios are probably gonna be around 12:1 if temperatures are colder than 32 at their highest. Somewhere in these areas, though, someone's gonna be colder than forecast and get really high ratios. It always is a possibility. Don't expect 10:1 ratios. Maybe 8:1 or 9:1. Again, only in the deathbands and what not.
Pretty much almost all models sum it up: Lead low over Kentucky or that area will break free. Then the main developing LP, which is around all those thunderstorms in N FL, comes in, and the Mid-Atlantic sub-forum gets hammered during the main event tomorrow if the right set up comes to fruition. And we get our main event. Right now, the first kicker is moving in and we still have our pretty strong suppression stream over N NE.
That's all i know right now.
