At this juncture we are probably looking at a weak Nina possibly transitioning to neutral as winter progresses. The orientation/location of the HP near the Aleutians is going to be a major factor in the winter outcome, specifically wrt cold air delivery to the midlatitudes of the central/eastern US.
New CanSIPS has the general look we want for getting cold air nearby, and the rest is getting some luck with shortwaves along the boundary. This longwave pattern has been pretty common in recent winters, so we know how this works.
