favorable after NYE? probably like 6 or 7/10. would probably last through mid-month before a relaxation as the MJO wave moving through the more favorable phases craps out. even if it's not super favorable, which is possible if the jet remains on steroids for some reason (nothing shows this) I highly doubt it'll be as crappy as the pattern now. the jet shouldn't be as strong
it's not a lock or anything but I think that once the jet relaxes, which it will, heights recover into AK and we get a much better source region
