One thing i've been noticing, Is the lead northern stream s/w is getting a few tics further east before it phases with the southern s/w which has allowed the surface low to track into BGM and then VT instead of Ontario, Were starting to also see the cold air sinking a little more south with some front end snows starting to show up in more areas, Something to continue to watch as we get closer, That's usually the time when models start picking up on the colder air, 12z Euro shows it as well.
