The GEM would be devastating for the Willamette valley. The eastern metro would look like a warzone with the east wind and heavy freezing rain.

Those totals would rival February 2021 in some places. And it looks winder here too.

I'm in the west Portland Metro (Bethany, just west of the west hills) and we get an accelerated east wind off of the west hills. The WRF-GFS is showing 50-55mph wind gusts here. That in conjunction with even a bit of ice would be damaging

Anyone got a good look at the ukmet? I am not privy to the good maps. Looks colder at least

Looks colder, hangs on until Saturday morning. It doesnt see the gorge well with its resolution either. Brief snow then about 0.5-0.75" of freezing rain

[TT-SEA]

Based on the observation map and wind... the low seems to be right over Lake Washington and Bellevue moving east.

[TacomaWx]

Good chance for a 1-2 hour burst of snowfall for a lot of areas that have had all rain this morning. I thought it would take until 10am for things to cool off at BFI it’s coming quick. Shame I have to go to work in 40 minutes in Milton lol. Will probably see some snow at work!

[Hyperbolic Trendz]

I just woke up in a cold sweat.  Did Mossman get snow?

[thisisacreativename]

41 and rain here.. Not sure if this area will even switch over in time at this point.

[snowbustcity]

Puking snow in NE Seattle. Definitely lost a good bit from the rain.

[van city]

New snow overnight.

my pressure bottomed out 5 min ago and winds just switched the WNW

Understanding winds around here when it comes to situation like this a bit more this morning and why the track of this low was important. Winds from the north funnels through the Puget sound but then have to split between the Strait and Sound. No such split needed for the southerlies. Can obviously see why the Euro was aggressive with the southern punch. It just didn’t punch enough.

Seems like models are back to showing a faster warmup but that's probably overdone. Mark Nelsen thinks we'll stay frozen until Christmas eve

I notice even the models that warm us up to near/above freezing by late Friday or Saturday keep us in the 30s or low 40s until the day after Christmas. Which tells me they are seeing gorge influence hanging on since the upper levels would dictate much warmer temps at that point. But it’s very possible they are overstating the quick moderation of said gorge influence.

if it heads straight east from there I would assume quite an i-90 convergence zone afterwards...ya?

[RentonHill]

Temp spiking and winds back out of the south. It’s over.

That was epic. I remember teaching that year and telling the kids on a Tuesday (I believe) before break to take everything home because I had a feeling that they wouldn't be returning, and sure enough, that was it for the year.

Does this really feel the same?

This similar as for today but not for the overall event as this one will be much more short lived.

I believe he’s happy with his treasured snow amount, enough so that he’s released “some “snow for us to enjoy in the South Sound.

I’m not sure precip will last that long, unfortunately.

Kind of looks like Manny from ice age

PDX is still at 36

[jakerepp]

2 minutes from my old place. Holy crap that's some insane rate!

Don't think so in this case... models have not shown that happening at all.    Probably because there won't be a north/south wind battle zone with cold air moving south behind the low.   

[yellowstone]

Flake size increasing with huge aggregates now.  Beautiful!

Help me understand this, if there's down sloping and 30mph winds out of the east how the heck is that arm nose in Clackamas county going to happen at the surface? 

The surface winds down there will switch to southerlies. The east winds will still be blasting from the Gorge but just won’t be able to reach that area at the surface. So they will be able to thaw out faster.

I stayed home. Post PICS and VIDS!!!

[BurienSnowGlobe]

Glued to the window in Central District. Will let y’all know if it switches over here because that would be a good sign for south of Seattle

[MikeInEverett]

Wow. Ok at least where I’m at right now it’s puking lol

I’m guessing they will see a bump to mid to upper 40s once things switch to southerly this afternoon. Hopefully will cool back into the 30s in short order this evening though.

I remember a few years back where as the cold air thinned, the obs at Rooster Rock, bottom left of photo, were 30, while up at Crown Point were in the 40s!

[snowbustcity]

Wow…total nukefest right now!

[Seattle]

It is absolutely nuking and puking snow. When do we expect the precip to end? I'd say it's snowed about an inch since starting.

[fubario]

pouring and 40 degrees in oly.

*reads script* 

i'm happy for all those up north getting an incredible snow event. you all deserve it.

[RentonHill]

Hmmm switched back to north and temp dropped 4 degrees in about 2 minutes. Suspicious. Sorry for spam posting but I’m right on the line!!!

Flakes starting to mix in….

[PuyallupChris]

What on earth. It was 40 degrees in Puyallup with moderate rain. Get to lower Queen Anne, and it was 40 and raining. I walk from the parking garage to my office. Rain.

Get to my desk. 39 degrees and absolutely dumping snow. Dumping. And now I see a WWA for up to 3 inches? 

I have no idea if I should drive back home or what. 

[bishbish777]

This looks like it's sagging south pretty quick, I think we only got a couple hours left unfortunately. It's beautiful outside though!!

[Cloud]

I expect it to get BFI soon by 10 am.
