The GEFS is actually stronger with the Alaskan ridge vs the 12z.

Looks like the awesomist ridge ever seen on the West coast, is starting to slip a little to far off the coast and that's letting the SE ridge rear its ugly head! I suspect it will continue that trend sadly!

It's way to far off to fret over a 300hr+ forecast. The signs are here for a major pattern change. So much doom and gloom nothing haha

It does pop a little bit of a SE ridge, but those aren't always bad if we have -AO/NAO and +PNA plus cold air around. It can prevent suppression and aid in confluence over the NE to get us those nice CAD highs.

Yeah, but in that instance on the 18z gefs if you take away the -nao, I bet that se ridge blows up. Ninja death grip on the greenland block!  The line must be drawn heyah! No further! :D

No doom and gloom needed IMO, going to be some fun and not so fun scenarios in the next few days. Although the SE Ridge is like herpes, it keeps coming back.

Robert(wxsouth) made a post on FB about how it's going to be turning colder.  Said its looking real interesting on paper. Didn't get into much detail.  But showed a map of both EPS and GFS of 12z. Stated how rare it was both models showing a full northern hemisphere high pressure out west. Of course both show deep trough.  GFS actually more east with the PV but stronger ridging over the Atlantic into Greenland as well. Really looking at EPS there is another weaker full northern hemisphere ridge too.  From Atlantic Greenland Arctic to east of Japan.

He's got his paysite back running. Gives very limited info for free now, but happy for him!

Folks are upset about the 18z GFS (storm on the day 14/15 is a lake cutter), but even that run would still have a major arctic outbreak behind it. 

Don't despair, next model runs will show something different. As always, the models really don't have a clue in the LR with this type of pattern change.

The EPS day 9+ looks really good.  A few events with similar pattern...hopefully it holds.

After the cold front comes through 6-8 and the trough sits for a little bit(200+ hrs). With so much energy is the N/S and S/S hard for models to handle. ATM both of them.  Especially depending how the S/S act will play a major role too.  With so much energy available all cards are on the table.  Ranging from clippers, Miller A, Miller A/B hybrids to Miller B. Wish y'all the best on a snowy winter.  I just want some rain.  Unlike last year's winter drought here.
