[Cloud]

Seems like Mother Nature decides to take control and comprise the models.

Still dumping snow in Kingston!  This is on the water looking north.

I'm right up the hill from there, close to the high school and middle school. It's been absolutely nuts all morning.

The treasure trove of cold air over the North Interior can sure change things quickly when the gradients go northerly.

Winds are picking up more than what i was expecting.

[snow_wizard]

The look of the sky has sure changed here.  Smooth slate grey instead of the typical mild / rainy look.  Winds are flat now.

Its not hanging back from this storm... its an arctic front later tonight.   

Here is what the 12Z ECMWF shows overnight...

Fair point. The initial Arctic front is moving down the Sound now (ushered in by passage of low), but then you have the big boy coming through later that will drop temps into the teens.

I would agree with that if the temp was 36 or even 38, but 42, I think we are shut out.

It dropped from 41 to 32 in Seattle in under an hour this morning.

Why are people talking like this is over?  Really bizarre.

Probably people frustrated. Not often you see snow in DT Seattle and nothing here falling.

will be interesting. Those fronts can drop A bunch of snow fast.

What I don't like is how the ECMWF has been shifting that band a little northward with each run... that tells me the arctic front is a little weaker than originally shown.

It's snowing places now that were at 42-43 an hour and a half ago.

just PNW things striking again

Not sure about that... at least not in Seattle.   ECMWF shows the crash that happened this morning but still shows temps in the 32-34 degree range all night.     I know... the ECMWF was too slow with the wrap around snow this morning.   But it takes a strong arctic front to have a flash freeze.   

Here is the 10 p.m. temps per the 12Z ECMWF...

 

Be aware it is already colder in the Everett area than what this is showing.

It is happening here at work. now down to 29 degrees and it was raining here 35 minutes ago. Cars outside are frozen.

For sure... the real cold air appears to come in from the east tomorrow night.   

[RentonHill]

Finally made it to 32.0 and its still mostly rain with some icy pellets mixed in.

I don’t see why it can’t be discussed? They based their decision off of a WSW that didn’t materialized last night. That was what the cancelation was about. You even said it last night you didn’t have a good feeling about it Jim.

Wind out of the north at a pathetic 2 mph now 

[T-Town]

Wind is trying to shift here.

I don't think people understand the dynamics at play here.

[seattleweatherguy]

Any more snow today? It has stopped here

Maybe so... but I want to see a strong arctic front plowing through western WA in the models and the ECMWF has been trending the wrong way.   

[SouthHillFrosty]

Looks like a river outside on my street.

I did say today would be our chance.  Just look at what is happening right now.  Snow line is plunging south.

There is so much low level cold so close already.  This is a weird scenario.  Snowmizer said he is already seeing a flash freeze where he works.

We want a 12/26/21

What obs would one look at to track that? BLI-SEA gradient?

[MR.SNOWMIZER]

There is only a dusting here at work but 3 miles north there is 3 inches. Insane boundry

This could be incredible when it switches over.

Snowing hard and sticking here in Burien.

29 degrees is freezing everything up already.

And maybe it will happen.   But I would prefer the ECMWF show it happening.   It was right about the warm spike this morning but too slow with the cold air wrapping around.

Euro going back and forth between 0" and 1" in PDX what a nailbiter. Good run this morning! DARE I SAY we should trend it to 1.5"

[lowlandsnow]

Is it snowing in North Bend?

Not yet... but its snowing hard in Issaquah so its coming this way.

[RentonHill]

Finally mostly snow here and down to 31.6. 

[JW8]

Absolutely DUMPING snow in Newcastle!

[snow_wizard]

The U District has dropped to 29 now.  Awesome CAA!

[TacomaWx]

Sea tac down to 32…42 in Milton but the wind shift is here. Gonna crash like a rock soon. 

[TT-SEA]

Snowing now at Snoqualmie Ridge exit to my west...

It’s gonna be such a close call… It’d be nice to have at least have a white table cloth set out before cArmageddon sets in Thursday evening.
