Looks like 850s bottom out at -18c for Seattle. Nice improvement from 18z overall.

-18 is pretty epic.  All we need is for the ECMWF to blink even a little bit and we are golden.

Oh my GOD. I saw someone in Rob's group post a map showing SLE getting 3/4" of ZR  before switching to snow.

One thing is for sure, the GFS 2m temp progs are still as ridiculous as they were back in January 2020.

It has that January 2020 vibe to it, but comparing the two is a little disingenuous. There is a tad more help from the Pacific than 2020, and last year there was a raging +NAO, which offered no help whatsoever. There are drivers for Arctic air, in fact better so than 2020, though IMO their influence may be overdone.

The Euro is a better model than the GFS, but that doesn't mean some sort of compromise between the two of them isn't still usually the most likely scenario when they differ so drastically.

GFS takes the weekend system well South too. WA stays cold and mainly dry.

I’m not comparing the setups, just the model’s insane cold bias with low level continental air.

Ah, I see. The GFS is very advection-happy overall, yeah. It does help though that we have an established snowpack up in BC, something we sorely lacked last year. Another ace up our sleeves I suppose. I still think we end up somewhere in between the Euro and the GFS.

Th truth is a compromise would be dead nuts on for all of us.  All we need is for the ECMWF to blink just a tiny bit.  That's it.

Another aspect is the cold is already there in BC.  It's having time to build up so it can flood in when the gradients become right.

Yeah I like that trajectory with the lows heading SE. Wish the Euro would do that too.

Heh. This where the IMBY comes into play. Not a good trajectory for Washington especially with an easterly gradient.
