I think the main controlling factor is how strong the SE US ridge will be. In recent years, it has been strong/persistent due to the very warm western Pacific making the last few winters mild in the SE US.
Right now we have a -NAO, but also have an -PNA. Not sure how that could affect things. Usually you need a -NAO and a +PNA to force colder weather down in these parts.
What is the PNA and would a +PNA lead to more ridging?
A +PNA tends to lead to less SE ridging. While a -PNA leads to more.
