[SilverFallsAndrew]

Bless my children with snow on this night. 

[Weiner Warrior]

That moisture up north is heading south for seattle and foothills. Looks nasty

[RentonHill]

Yo looks like that last bolt landed on top of @JW8 or @The Ms. Anthrop ?

[SouthHillFrosty]

Oly is back in the sweet spot!

[The Cats Meow]

Will it make it to Pee Allup?

What does the magic 8 ball say?

If anything makes it to the swamp, it’s rain. There is no god in the swamp

Radar is fascinating this evening... that northerly c-zone appears to be passing energy off into a new c-zone over the I-90 corridor.    Very active night.    

[TacomaWx]

Looks like sh*ts about to get real across the sound.

How much snow do you have so far?

Very rare to have a c zone developed over my area but it is beginning. 

[Doinko]

RGEM still looks good

[MR.SNOWMIZER]

The area from Olympia and south about 50 miles will be the hardest hit area tonight imo in Washington.

Yeah... can't remember seeing a c-zone form that dramatically to the west.

I hope the RDPS/NAM is right about that decent band of snow just over PDX to the north of that low

This system has way more moisture in it than what has been shown in the models it would appear.

I will predict 6-10 for you tonight. 

[Doinko]

Really nice looking C-Zone

[Perturbed Member]

Radar lighting up pretty good to the NW. 36.4F with a dp of 30.7F here. 

[GHweatherChris]

Snowing here.

Not sure... ECMWF has been insisting most of the c-zone action for King County is done by 10 p.m.   

It also showed copious moisture in King County and the central Cascades up through 10 p.m. so don't think there is more moisture than shown.   

[Cascadia_Wx]

45/38 day here so far. The high was at 2am. Afternoon high of 44 with some chunky showers at times and a couple scattered sunbreaks.

Down to 38 now with a DP of 30 and WNW winds. Nice to see the DP already below freezing. Excited about the potential for later tonight.

Heaviest showers look like they’re heading just south of Washington County.

I mentioned a few days ago that the ECMWF was showing a double c-zone and likely convection this evening.   It has been showing this event tonight for about a week now. 

[Requiem]

Pretty dynamic system-- fair to say there may be a surprise or two as it comes in.

[Katzen]

Loud crack of thunder!

and getting pretty white

And I'm getting screwed in the middle!

That was close! And very long thunder. Where are you at ?

[Deweydog]

Dad says they had THUNDERSNOW at the coast. But he’s old…

[bainbridgekid]

Drove up to Marysville and it was dumping huge flakes at sea level but not sticking. I’m right along the Southern edge of the CZ right now near Paine Field with light wet snow.

Nice!   Haven't heard any thunder here so far. 

Main convection seems to be closer to the Sound.    Precip is much lighter now to the north of the convective yellow band.

It stopped.

[Snownerd3000]

My wife and son are stuck on his ski bus at Snoqualmie trying to come home. Hoping Westbound stays open long enough for them to get home. Bus driver was an idiot and waited until it was time to leave to get chains on the dam rig.

I’ve been watching that little comma develop offshore to the NW all day on IR satellite. 24 hours ago it was just south of the Aleutians, now it’s almost to Vancouver Island as of the most recent frame.

Stations pretty uniformly in the 32-34 range-- whatever does fall at this point in my area at least will likely be snow. Just about getting the moisture there at this point.
