Pattern December to Remember

I bet the unusually warm gulf of Mexico (for this time of year) is not helping our storm track and thermals so far this winter. Also led to the deadly tornadoes west of us I saw from multiple sources.
 
IMHO, I think the models are finally starting to focus in on where the cold air is going to be. The west. Basically like any other year. Will it eventually move east? Maybe. It’s been quite difficult for that to happen the last several years. DE104F94-011B-42E5-B244-0DC0C2C2B1C1.png
 
It is quite the pattern squeeze play though.

-NAO / MJO Phase 7

vs.

-PNA / -EPO

And with the pattern looking even more volatile the 2nd half of the month, hopefully we won't have to deal with yet another (3rd) severe weather outbreak...
 
How were the EURO/EPS at 00z? Didn’t see many posts about it
 
Not surprisingly, the GEFS breaks down the ridge at the end of the run. 85E0AE7C-2208-4BC2-95A4-D975DC30E166.png

The GOM temps have nothing to do with our thermals or storm track if the upper flow is oriented correctly. We simply need a cold air source and a pattern that doesn't feature a bubble ridge in the center of the country.
 
With the wave train moving across the US out of the trough in the pacific starting this weekend and lasting through at least Christmas and maybe after I'm still not entirely sure I'd get too attached to warm/cold. One mis step in model amplification/non amplification makes the difference in a clogged up SE Canada and an ever digging trough in the east or a flat slightly ridged SE. Chances are we land in the middle with a more variable day to day pattern but the potential is certainly there for a really warm/fairly chilly change

I'm still a believer that we will need the MJO to push into phase 8 to change things up. It's unclear if it will make it there.
