Day 9'er

[Meatyorologist]

It's trying to go places! Pretty colors may ensue...

[Gradient Keeper]

Day 10 Not quite.....

[Meatyorologist]

Hey, I said may... ¯\_(ツ)_/¯ That longwave trough lost all jet support and flew out into the Prairie.

[Meatyorologist]

Alright, I'm off. Desperately sleep deprived. I got a couple of hours after 9pm, bet then woke again at midnight. Oh well.

Still very close and I'm really optimistic. Onto 12z

12z GFS in 4 hours 47 minutes

12z ECMWF in 7 hours 2 minutes

[wxmet]

Very close. We can make those adjustments leading up to it.

[TigerWoodsLibido]

Productive night shift. Bed time.

What a gorgeous morning for @AlTahoe

12z GFS Day 5 MUCH healthier ridge merger

(Past 4 runs)

[Gradient Keeper]

Day 6

(Past 4 runs) Block is many notches further west

 

[jakerepp]

How about this beauty from North Georgia this morning?

[Gradient Keeper]

Day 6.5 (Past 4 runs)

[Gradient Keeper]

Not ideal would want the block few notches further west yet and more amplified. Can't complain though.

[Gradient Keeper]

Day 7 Block is a bit too wide, bit too far east.

12z GFS definitely a little bit chillier around D7/D8.

Interesting how its flipped the temps on east/west of the cascades. West noticeably colder than the basin. Whats the interpretation of that, if anything? 

[TheNewCulverJosh]

Pendleton AFD is onboard somewhat!!!

 

On Thursday, a high amplitude and anomalously strong ridge will
build over the eastern Pacific, and WA/OR will be on the front side
of the ridge and under a northerly flow aloft.  The ECMWF slides a
backdoor cold front and shortwave trough over the region.  The GFS
and Canadian are about 6-12 hours slower and are weaker with the
shortwave.  Nevertheless, there is a good chance of snow in the
mountains and valleys Thursday night and Friday, and snow may be
moderate to heavy.  The NBM appears to be on the low side of the
PoPs and QPF/snow for the lower elevations during this time.  Due to
some uncertainty in the Day 6-7 forecast, will leave PoPs and snow
amounts as is.  Wister

Cave you ***** Cave!!

 

[MR.SNOWMIZER]

Not everyday you see a 1058 high working into Montana.

[Gradient Keeper]

Block is so much stronger the wonky cut-off on previous runs is deflected running into a brick wall

[SalemDuck]

the 500mb pattern is trending much better on the GFS

End of the 00Z EPS... it stays chilly but the arctic air stays north of the border.    Could be a good set up from some overrrunning.

I could be wrong, but overall pattern evolution seems pretty similar to Feb 2018.

[MR.SNOWMIZER]

[Gradient Keeper]

This looks quite a bit like December 2008 to me. BC slider heaven.

[MR.SNOWMIZER]

Hr 234-270 Classic region wide snow event. 

[TT-SEA]

12Z GFS is WAAAAAYYY better.

Is that the west side of the lake? I remember the window on the bench door of my mom's suburban shattering. It was cold and snowy like this. 

[Gradient Keeper]

This is the best run of the Winter (so far) not even debatable.

[GobBluth]

should be a fun battle of cold canadian air and increased sun angles. what's the track record of sub freezing highs once we get after feb 10?

[Gradient Keeper]

I'm just hoping to see some improvement on the GEFS with the ridge merger/retrogression.

[Gradient Keeper]

[MR.SNOWMIZER]

Remarkable to see this 2 years later to almost the Day!!

[GobBluth]

fun to note that the GEM led the way in this pattern switch, assuming it happens.

[Gradient Keeper]

GFS was REAL close to turning cold by just Day 7...
