Iceresistance is that a good or bad thing for us?
Remember that a +PNA means that the Cold Air gets pushed more towards the East Coast?

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)

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
