One thing to look out for in terms of seasonal trends for the future, the Canadian/Euro are persistent with having the upcoming troughing/cold get caught in the central US before reluctantly scooting east, delaying the cold wave. This allows for a bit of temporary ridging, or at least seasonal/slightly AN temps to persist longer in the East. The GFS doesn't do this, and in fact the GEFS has trended colder for the East within D8/9.
