Remember that a +PNA means that the Cold Air gets pushed more towards the East Coast?

We want a neutral PNA.

Ah gotcha well im putting my money on a neutral PNA, im not buying the GFS, its too far east, the euro has a more neutral pna solution

So did the 12z GFS . . .

Iceresistance its 12+ days out, its going to change alot, im not gonna put a whole lot of trust into the PNA right now, especially since the 12z Euro favors a more neutral pna phase,

The CFS is still very consistent with the December Cold Wave Round #2 (And maybe #3) around Christmas Week, & it has finally jumped up with the Euro on the Chilly Blast on the 12z run (It's behind every model run by 1 run time)

0z GFS has a more Neutral PNA on the first cold wave compared to the 18z GFS

The 6z GFS is featuring POWERFUL Highs in December.

1067 MB & 1060 MB at the same time


Another 1059 MB, over Montana


The Powerful Blocks over Alaska & Greenland will do the trick.


Very Cold Air comes screaming in with these Powerful Highs


3 BIG Winter Storms are also in play


24-Hour Kuchera Ratio Snowfall

Nothing even remotely close to snow down here lol...yet

0z Euro has a more positive PNA

We need that postive to go kick rocks lol

I forgot to mention that a Negative PNA would also be nice since as it turns positive, the cold air from the West Coast will eventually come here

GFS 06z has a very light freeze in HOU and mid 20s in CLL on Dec 11. Not unusual for mid December. There does seem significant support behind the cold mass (-15°F to -40°F in Montana, Dakotas), so the unusual part could be the length/reinforcement of the cold snap.

It's a long way off. We'll see.

12z GFS is surging it MUCH faster compared to the 6z!

End of the 12z run on the GFS has a Snowstorm for DFW & Oklahoma.

Iceresistance yup i saw that

True, but 20-50°F warmer in that run in the Rockies. I expect this fantasy to fade away.

18z GFS trended colder again compared to 12z

I'm about 50/50 of this becoming a reality

The trend is our friend
