Would be pretty batsh*t crazy if PDX didn't even see a freeze out of this. Probably will happen Tuesday night but you never know.

Considering how epic the snow is up there this is a shame.

 

Nature in charge! 

As it should be!

i have my snow gear, chains, water and a blanket in my car as per TWC

And snacks !!! 

[Rubus Leucodermis]

Have 3-4" from yesterday and last night in Glenhaven, while where I work in Bellingham is pretty much bare

 

That was frustrating to watch in progress on the radar. A big cell was heading my way, steadily making progress. The edge of it reached me and it stopped, sat in one spot for an hour, then disintegrated. Decided to enjoy the proceeds of it even though they weren't at my house by taking a mountain bike ride / hike at Lookout Mountain this afternoon. Was quite lovely.

 

Outflow winds still blustering here in north Bellingham. 17 degrees and falling, forecast low tonight is 13. It’s a nice taste of winter without winter having to last for months and months.

[Phil]

Toss it Phil?

 

Probably. But it’s still sort of a jump ball.

[Blizzard777]

Not to brag, but I predicted that one too. And I was trolled relentlessly because it wasn’t strong enough for some people.

 

I really can’t win.

10 points awarded!  

That’s all I can do 

[HighlandExperience]

18z Euro remaining with the idea that eastern parts of Snohomish, King, and Pierce counties will do alright tonight. Looks pretty similar to 12z.

 

Through 10AM Tuesday...

 

 

 

I think ill take the EURO over the NAM. Crossing fingers.

Colder cloud tops moving over/developing in the Puget sound region.

[GHweatherChris]

There's the spirit!

 

Feeling like this is the best shot for some of us and we got the Euro in our back pocket, so might as well go for it.

 

Yep and the Euro so far is showing more tonight for me than what it did for last night!!

[Front Ranger]

Radar returns intensifying over Victoria as they move east.

[GHweatherChris]

Precip is definitely improving off shore.

[snow_wizard]

Well I'll be dipped.  I'm in one of the better area on the 18z Euro snowfall map for tonight.  Shows a good 3 inches here!

 

Currently snowing and I've had 1.2" for the day so far.  Looks like the Arctic front is moving south.  Sub freezing temps have reached north King County.  Everett is currently quite a bit colder than the ECMWF had indicated for this time with 27 degrees.

How do you measure that?

Something is happening in the atmosphere... but nobody really knows what exactly it is 

[GHweatherChris]

It's probably just my eyes, or a little bit of hope, but the latest loop of the radar looks to have a slight rotation to me centered right over the Sound and moving E. Showers near Tacoma move due E and then as they approach the mountains they start moving more N.

 

This radar below kind of shows it with the 3 hour loop. I'm probably just seeing things.

Radar trend is solid.

Radar returns intensifying over Victoria as they move east.

 

That stuff has been streaming east since this morning. The Fraser outflow always eats it up. All Whatcom County gets out of it is flurries.

You can actually access it from the East side, so the ski area is open. Great for Wenatchee and Leavenworth residents.

[snow_wizard]

SEA is now 32 with a dp of 28.  The north wind is doing its work.

[TacomaWaWx]

Radar returns are picking up it looks like. Stopped snowing for awhile but it's snowing again and 33 degrees.

[jcmcgaffey]

I think it's between Kent and Federal Way based on surface wind vectors, but it's clearly no longer a sharp air boundary as it was yesterday.

. I was looking at several maps and they show further back. The surface analysis map from NOAA shows it just north of Olympia but other maps are showing around Tacoma.

[Requiem]

Wonder when I’ll see a flurry or two from this thing...

Which is, what, maybe 15% of their clientele on a good day. Sucks to be them. They’re losing lots of business.

PDX not getting cold? That is definitely some oddball stuff!

[snow_wizard]

How do you measure that?

 

A really simple answer is just look at the infrared sat pic.  The colder clouds show up brighter.  Right now I expect the relatively warm moisture streaming in from the south is interacting with the colder air here.  We may see some surface interaction of dry cold air meeting the moisture also.

[Deweydog]

Later.

I am so glad this forum thing didn't exist when I was your age, I could see myself in your shoes if it did.

 

On the bright side, I think things will work out for you, just have patience.

[umadbro]

I see Tim got banned. That's mind numbingly stupid.

Precip will probably develop over us like a convergence zone.

Suspended, he'll be back in glorious new form. Or just the same old.

[TacomaWaWx]

looks like light echoes are going on all over the sound on radar. They're not virga because the light blips are producing some snowflakes here.

[GHweatherChris]

Feels like the good old days, watching WWE Raw and waiting for snow!

[Blizzard777]

32.1 as if it knows not to cross that line.....Mother Nature is smart 

[SilverFallsAndrew]

Temp down to 32 with some light snow falling. Looks like winter.

[GHweatherChris]

33°

[BLI snowman]

Yeah.... with -10c 850mb temps it certainly would be.

[MR.SNOWMIZER]

28 here with light snow falling.

[Deweydog]

[TigerWoodsLibido]

40F with some light rain. Been basically right at 40F all day.

 

Got down to 37F overnight so we should have a barely below avg temp departure.  First since Dec 26.

[SilverFallsAndrew]

Any chance more low level cold can work into the gorge before the mid-week system goes north?
