I think most models do not do well when trying to bring cold air into the SE. GFS is really bad. It shows it, then it gone for days and then picks it up again. I know you cannot look at one or two runs and bank on it. U.S. models still need a lot of work. Just my 2 cents worth.
Well well what do you know
Yep, looks like the GFS caved to the CMC.
Went from Doofus myself to pants nuked 
GFS is a lot like the USMNT. Hype but always folding. EURO is the USWNT.

Not enough cold air to tap, though. But it's too far out for details. Waiting on the Euro...

No guarantees it won't flip flop 10 more times....

Folks, this is why posting those LR GFS maps that show warmth or cold is dumb and trolling. The model has no clue if it's going to be 70's and tornadoes or 25 and snow from run to run. I guarantee you'll see it flip again by 0Z tonight.

Then everyone is a troll. Because no matter what warm or cold everyone is going to post. Warm lovers will post the warm runs and cold lovers will post the cold runs. But you’re right. This gfs model is absolute garbage

“Homegrown cold air” of Canadian origin can get the job done and there is plenty of that.
Drastic changes in the pacific this gefs run, much improved and a big step to the EPS, under 200 hours

Biggest change is the Pacific becoming more favorable over the past 36 hours of model runs. Looks to sacrifice the strength of the -NAO, but could be more productive in the long run if there's enough cold air.

Why is that? Why do we lose a strong -NAO once the pacific becomes more favorable? That’s so frustrating

Process of a tall pacific ridge destroy -NAO because Arctic energy is trying to plow through the block as the tall western ridge gets established
Much more extended pacific jet this gefs run contributing to changes
So is this the last time GFS changes?

Even in the southeast we don't need every three letter index on our side to get a storm.
