Wow Everett!

[mtep]

Snow looks to be slowing down here. Very nice little surprise while it lasted.

We’re getting the sloppy firsts. SW areas will get the sustainable seconds.

Pretty good bet that the dynamic stuff this afternoon and evening will extend well into Clark County.

The snow is really dry up here. Even with just a trace so far its blowing all over the road

Yep even compared with yesterday. It has that dry ice look with the blowing snow. If we had another inch or two I could see them doing a late start but with just under an inch here no need. Very pretty to look at. 23F at the moment.

[ShawniganLake]

Just light flurries here but there are some sea effect streamers setting up north of here. Nanaimo airport currently 1/4 mile visibility in heavy snow

Yeah, seems like deformation wants to keep up for most of the day at least periodically. 

[Cascadia_Wx]

Definitely getting some 2/20/18 vibes looking at today. Although the airmass moving in tonight/tomorrow looks a couple notches colder than that one, and the arctic front this evening should be a little more dynamic for the metro area. At least that’s the plan.

[Timmy]

People like Tim and Andrew look to building a snowpack through next week. Could be pretty epic up above 1000’

[TT-SEA]

[SpaceRace22]

So no one is going to mention that the Canadian RDPS just spit out 3 ******* FEET of snow in Portland? Shows the temps dropping below freezing by noon and then absolutely nukes the city.

[Deweydog]

WINTER WEATHER ADVISORY

[SnowySeeker50]

Currently 31.5 degrees. Unfortunately too far north for me to get anything out of this so looks like the next chance is this weekend

[SpaceRace22]

Holy ******* mother of god THREE FEET?

[MR.SNOWMIZER]

Going to be interesting to watch this play out, that low basically sits there and spins for about 24 hrs starting now.

I believe there will be some decent bands rotate up through puget sound, the sw washington coast looks like they will do really good.

More so for Andrew.   Not as impressive up here.   Maybe 3-4 inches Sunday morning but then we get a few hours of a roaring SW wind and then the focus of the precip is from Oregon southward early next week again.

That model did very well with central puget sound this morning.

[Timmy]

Just for Friday Saturday next week…

This is a great example of why you just cant look at the models and ignore the overall pattern. This is impressive snowfall for not being modeled that i know of.

[Timmy]

I don’t expect this to verify but this pattern above 1000’ is glorious.  Was it March 2011 or 12 that did something like this?

Looking like a impressive 72hr window out here for some heavy snowfall on and off. Timing will be very important.

Honestly starting to get worried I’ll be too far south tonight based on some of the most recent runs this morning. Clark County always owns this area for snow events anyways. 
 

Give me the weenies.

[Eugene Snow]

Looks close to 2” here, with another 3”-5” to come?!

 

WINTER WEATHER ADVISORY REMAINS IN EFFECT UNTIL 10 AM PST
THURSDAY...

* WHAT...Snow. Additional snow accumulations of 3 to 5 inches.

* WHERE...Central Willamette Valley and South Willamette Valley.

Probably 700-1000ft during the day and around 500ft at night or less away from water. Good pattern for some places for sure.

Wow the 510 thickness line back doors to about 15 miles east of us tomorrow morning. 

Ya over here in Redmond we’re looking at a low close to 0 if not below by tomorrow morning. Depends on if there’s snow cover of course. 

[runninthruda206]

Heaviest snow of the winter coming down here in Fremont on the backside of this band basically nothing on the radar. Really interesting

Yeah, but you should have plenty of chances next week

Really hoping for a decent metro wide event with a focus on the south and west metro. You guys are due.

[Timmy]

This has incredible potential for areas with elevation especially.

Tigard should do really well once we shift to a more frontal dynamic.

[Cold Snap]

It’s crazy how scattered the snow showers are. There’s nothing on the ground at Woodinville-duvall road at the west snoqualmie intersection but the Avondale intersection has quite a bit.

The temps are concerning but i'm hoping that changes with these heavy bands down there. I want the entire fuking area to get hit from Eugene to Seattle.

Looks like no precip for my area today……I guess I was due to be skunked lol

Tonight is a better chance but not 100%

Winds are still from the south here so it’s not too surprising that temps are still marginal. It will easily be cold enough later today though. Not too worried about the temps for the main show here, it’s all about where the moisture sets up.

[Tyler Mode]

Over 2" now and puking snow.

[SnowHawks]

You mean Eugene to Bellingham?

[Doinko]

Dumping snow

[SpaceRace22]

Posting the wider map of that insane RDPS run. Other items of note: The South Sound scores on it, and Coos Bay also gets 2-3ft, lol.

This would be the largest single snowfall in Portland history if it actually happened, right?

That bullseye is almost right over me. I'm really liking our chances

[T-Town]

Nothing happening in Tacoma. A brisk north wind and some broken clouds.

I think there'll be plenty to go around. The arctic air advecting into the low is a great mechanism for widespread lift everywhere, and this isn't one of those arctic airmasses that stops at Olympia.

The GRAF increased totals to 10" for my area. Dumping snow already. Could be an amazing snowstorm

[RCola]

Solid 0.75"-1" on the grass in Belltown. Nice little surprise. Maybe this year's curse will be lifted.

This is going to be a big event for you. 8-12 easy from what i see on the sat and radar.

December 20-22, 1892 is the largest official storm of record in Portland. About 27" in 48 hours. 

Some pre-1870s storms like January 1857 and January 1866 may have been a bit larger but no official records exist from the city then.

I really think we’re going to score tonight. Models really seemed to underplay things so far as seen by what’s happening up north. Odds are pretty good IMO for 1/2” atleast tonight. 

[RentonHill]

long range GFS continues to tantalize

Lovely view of South Lake Tahoe on the way up right now.

I can see my house (kinda)!

Just to the right of that big white patch (meadow)against the shore line. 

[thickhog]

Portland NWS still thinks nothing noteworthy is happening later tonight. Guess we’ll see.

Can you imagine if 2-3ft fell across the metro after the NWS forecast literally 0"? I can't even imagine the chaos that would occur in the city of the RDPS scenario actually occurred tonight. No one in Portland who isn't a weather nerd is expecting anything significant.

[Cascadia_Wx]

Snow has let up here for the time being, but looks like more moisture could be rotating up from the SW soon. Nice coating on cars, trees and rooftops with even some slushy accumulation on the roads. 34 degrees.
