Just hit 35 here so I doubt we see anything too interesting until tomorrow probably. 

Just saw the radar seeing the moisture sweeping N.  
Something fell out of the sky a bit ago but I wasn’t paying attention.  Nest cam didn’t show any white flakes either

Snow here, but it was brief. A nice surprise!

Interesting, it’s still largely snowing here. Occasionally mixing and then a huge burst of snow returns. It’s kind of fun to watch.

12Z EPS shows warmth from coast to coast by the end of the run... pattern reset might be in the works.

Nothing here in south Everett, been staring out my window for like an hour now lol. Who knows, maybe this will be a good preview for where the PSCZ will set up tomorrow 

Welcome!  

I think you will be in a good spot tomorrow night.

Still pretty interesting we’re already flirting with snow this early on. 

It's snowing and starting to stick at 1000ft asl just to the north of here, the air column has certainly cooled down enough for it in heavier showers:

Just got back from replacing back brakes on my Mustang. Went from 32 to 35 but it felt like it got colder throughout the morning cause it’s freaking cold  Got the mug of coffee ready.

Where’s the arctic front now?? Can someone set up a bot to post its location every hour

[Requiem]

Also worth mentioning that those east winds on Wednesday-Thursday could be absolutely gnarly in the wind prone spots

Seeing some flakes in Shoreline on I-5!

[TacomaWx]

I get the feeling when the arctic boundary moves through the Puget sound Sunday night it’ll be more snow then we think. Over performance is common in Arctic front situations.

Thanks! Tried joining earlier but maybe I'm not so good with technology  took me forever to figure it out. Regardless, this forum is a great resource for my model riding habit and I appreciate yall.

Also had snow falling on this date in 2016 and 2021!
Here is what my chilly driveway looks like currently.

OpenWeatherMap api will give you pressure readouts along the path. You should be able to pair what should be a sharp recovery of pressure and a tick-over-tick drop in temp as the boundary.

I think you can do it.

Looking at the EPS spaghetti chart the OP is pretty tied to the EPS. Dips a bit below on Wednesday. But there still is a pretty sizable camp that goes full arctic so maybe could swing back the other way

[WildrootParable]

Just got my wish! The precip has indeed switched over to flurries! Whatever else happens, I am pleased. 

[MR.SNOWMIZER]

Just by looking at the satellite loop it looks like the front is stalling.

[MossMan]

Even 80% little snowflakes here in downtown Stanwood where I am currently at which is at like 1 foot above sea level. 

[Cold Snap]

Just got caught up with everything! I really think the surprise snow this morning bodes very well for snow chances tomorrow!

The 18z NAM is a bit juicier with precip later this afternoon. Shows snow north of Seattle:

[yellowstone]

Was driving around but a flipping back and forth between drizzle and big fat flakes across north Seattle over the last 90 minutes. Very minor accumulation in spots. Largest flakes I’ve seen so far this year. Hoping this is an indication the models have been underestimating the moisture. Nice surprise for sure.

Ah. I thought u were an SDE. I will try to possibly set one up if I have bandwidth today.

Nam shows a very rare arctic warm front stalling near MossMans dwelling. 

[snow_wizard]

Some good news on the EPS.  One is 850s for the two cold shots are a bit better than the 6z (while a TAD higher than the 0z).  The other is it shows most of the precip on the possible ice event going well north.  That second point is great in my view.

I just staged the plow in the garage for easy access!

Interesting.  The stream of low clouds sweeping in actually being caused by the Arctic air pouring out of the ocean to our north.

[KingstonWX]

Is it time to camp out in my office and waste the weekend riding models and arguing with mets on twitter? My body is ready.

guess this could be starting to become quite serious judging by the satellite.

That was expected thoughI think. Not supposed to keep moving as fast as it did. Now if it's still stalled Sunday night, we worry.

It was supposed to slow way down today and then slowly move south.

[Jbolin]

Hey @MossMan Don't you dare take the plow off the lawnmower.

I really want you to have a good Xmas.

Know what I'm sayin'

Good snow potential for the entire weekend.  The focus is north of Seattle today and then working south later in the weekend.

The models have round 1 well in hand now.
