Everything to Dec19-29 will adjust (I've been looking at 4 model runs a day for 20 years). +PNA Dec19-29, will give us a less pronounced -EPO, and because the Atlantic has been negatively correlating, probably less of a -NAO, although we have developed a -NAO tendency around Christmas since 2014, happening 7/8 years, with an average +120dm anomaly, vs the -60dm +NAO for Dec-Mar in the combination of those 8 Winter's. (re: 18z GFS ensembles) I think the -NAO tendency for Christmas 12/25.. will adjust to -EPO/+PNA, so watch for that gravity. 12/25 -EPO/+PNA and 12-19to29 +PNA.. besides that the rest of the N. Hemisphere pattern likely will flatten out/neutralize, LR models for the next 4-8 days will adjust accordingly<-.
