Pattern December to Remember

Interesting because the ensemble mean has shifted warmer around Christmas, and as you pointed out yesterday, most of the gefs members that were warm around the holiday looked cooler afterwards. Maybe we’re seeing that cluster of members win out?
This is the first time in a while I've seen more weight on the eastern trough than the westgfs-ensemble-all-avg-nhemi-z500_anom-0822400 (1).png
Obviously very late in the run but nice to see.
With that the mean is cold almost nation widegfs-ensemble-all-avg-namer-t2m_f_anom-0822400.png
 
Don’t hate the look. Liked where the GEFS was headed.

Yeah the -NAO looks like it's becoming stronger than the Aleutian ridge. Good trends. Those are the positive signs I look for.

It's an interesting look on the euro with the really favorable nao but the less than favorable pacific. It would probably take time for us to really work in any cool to cold air probably not behind the Christmas eve system, and likely not behind the next but all in all it's far better than 588 dm heights over the region

Sounds like last winter all over again. Solid -NAO but horrible pacific

Yeah I've been thinking maybe the last couple days of the month into the 1st week of January all along. If that's going to happen we should start seeing it show up at the end of modeling consistently over the next few days. I never was big on a before or just after Christmas flip.

Weren’t you saying the end of January?

I was hopeful that we could muddy up the pattern enough that we landed cool to cold in Christmas day even with the overall background of warm but that's looking less likely unless we catch a break. Certainly like where the 2nd half of the 12z gefs and 0z eps went

-NAO becoming more and more prominent on each successive model run, I'll take my chances with that.
