6z up til now looks ready tO deliver.

my eyelids also look ready to deliver. 

[Slushy Inch]

Much better GFS run if it keeps digging.

[Brennan]

6z and Christmas tree.

[Slushy Inch]

Still a huge difference... Maybe trending towards Euro though.

[Slushy Inch]

Slow artic front.

[Slushy Inch]

Here we go again. GFS snowmegadon. 

[Requiem]

Pretty godawful run for Oregon so far. But I suppose it's just the crappy GFS...

[SouthHillFrosty]

Night Shift is popping!!!

[RentonHill]

Almost like the Euro except the Euro doesn't extend to the coast 

[RentonHill]

Classic double hot dog block at day 10. These were much more common in the 20s-30s

Stronger offshore flow to. Good run so far.

[Requiem]

Pretty much the entire country is in the freezer by Christmas Eve. Insane. 

[Requiem]

That outflow would be incredible.

Would be a high impact snow then ice storm for much of the region if this verifies.

[Christensen87]

CFS not on board…yet.

Euro is absolutely insane! What a run!

It is significantly colder than expected this morning! Temp: 30.7 with some foggy conditions. Low temp: 28.9. 6z GFS was sure nice, but of course it is a huge outlier. The ensembles are a step back. Unfortunately it just looks like the trough may not dig much over WA/OR. We need to see a significant improvement with 12z/00z runs/ensembles today to dig that trough. I just don't think the ridge is going to cooperate to provide support for it.

[Gradient Keeper]

Anyone know how the 6z EPS is looking?

[Gradient Keeper]

It must be disappointing if no one has posted it.

925mb cold pool continues to develop and deepen over eastern Washington and portions of the Columbia Basin. The RAP 4-6hr forecast shows it expands westward.

[TT-SEA]

Still cloudy this morning and the ECMWF shows it stays fairly cloudy until tomorrow afternoon.  

[The Cats Meow]

How is the timing looking on the arrival of the cold?

Phone app yesterday morning had the valley getting colder Friday night/Saturday.  Phone app in the afternoon yesterday then pushed it to Sunday.  Now this morning it doesn't have it getting cold until maybe Monday/Tuesday.

Delayed but not denied?

Why do you care it’s all gonna slide east according to you

[TT-SEA]

00Z EPS was slightly farther north at 144 hours compared to its 00Z run but basically the same... and the control was quite a bit father north at that time and closer to the EPS.
