Fwiw, today's consensus MJO forecast at least suggests that it will go back into the circle by 1/27 and then quite possibly wind around counterclockwise into or near the left side of the circle as we get to late into the 1st week in Feb. So, from the MJO perspective, alone, there's at least a reason to think that a decent cold period COULD return to the SE US by late in the 11-15 day period. OTOH, warmth has been handily beating cold for the winter to date and the MJO is just one factor with only tendencies associated with it. It sure would be nice to get a period of sustained -AO/-NAO. Unfortunately, the GEFS mean isn't predicting either at this time. Then again, neither is anywhere close to being required to allow for the possibility of a major SE winter storm.
