December 2016 Observations and Model Discussion for the Pacific Northwest

[ShawniganLake]

Seems like the low is further east than the 18z Gfs had it. Certainly further east than I was hoping. Possibly something else spins up in its wake. Maybe!

[SilverFallsAndrew]

Light snow now, already a dusting. 

[The Swamp]

I've dropped to 38.5

 

We'll see what happens later tonight.

 

Hopefully everyone can get a long in here in the coming new year.

 

We are a very diverse group.

 

Some of us live at Snoqualmie pass and always get snow.  Some of us live in the swamp and rarely see snow.

 

Can't we all just get along though?

Further east would be good for later on....

[Jbolin]

On you map... the low should up near Ladysmith BC

Current radar loop suggests it's ( Low ) actually overhead of KBLI

I wish MLK Jr. talked more about snow equality for all elevations.

No one lives at Snoqualmie Pass... Phil did at one time though.

I don't think the low has closed off yet, that wasn't expected until later this evening. Things won't get interesting out this way until that happens.

I also posted that earlier ( about 30min ago) with a screen capture.

Yes... appears to be there now. Moving inland pretty fast.

[luvssnow_spokane]

That is what I posted just a bit ago. It is moving SE. You commented on it and said "no"

[FroYoBro]

Still not much warming in the Portland area ahead of the precipitation. Some of the cooler spots may be able to get a little sticking snow.

Scappoose has dropped to 34

[TT-SEA]

It was farther north at that time and its moving inland and east into BLI.    Moving fast.

 

Checked again on the loop... its NW of BLI yet.

Wasn't that Stampede Pass?

[Skagit Weather]

Looks like I'm going for the cycle up here with snow amounts. The first storm at the beginning of December brought 1". Then we got 1/2" two weeks ago and 3/4" last week. I am now sitting at 1/4" for today, although that could be bumped up if another band runs through. It had dropped to 33F, but it's popped up just over a degree to 35F. Not that I'm complaining because I've loved every time it snowed, but never have I had so many snow events with so little snow. It will be interesting to see if we can get anything over 1" before we moderate out of this.

[TT-SEA]

He skied all the time at Snoqualmie Pass though. 

[Weather101]

Picked up just over an inch

[Gradient Keeper]

Winds are still from the south way north of where you place that low.

Switch to north winds along/north of BC border

[MR.SNOWMIZER]

kinda hard to live at stampede. I have snowmobiled there for years. The only structure up there is the weather obs house. There is a few cabins just off the highway on that road though.

Yep... switching to north behind the low.   Watch the new MM5 NAM loop for SLP for the next 24 hours.

He had a house up there.   It was lovely but too hot and dry in the summer.  

[TT-SEA]

The L certainly looks to be moving more East than South and radar looks fairly dry behind the front.

 

Will all be up to the CZ that forms later if we get additional accumulation. Not sure with the more Eastward movement if that will be more or less likely to develop.

 

 

The air mass is so marginal on the MM5 NAM for the next 24 hours... not until tomorrow night at this time does the colder air arrive. 

[FroYoBro]

Looks like it is snowing hard at Staley's Junction. 

[The Swamp]

Ferocious winds picking up here now.

[SilverFallsAndrew]

Thoughts on the 00z NAM?

[MossMan]

Who's pumped for the 00z's?????

[MR.SNOWMIZER]

Ferocious winds picking up here now.

75mph?

[TT-SEA]

Got a quick 3/4 of an inch here over the past half hour or so. Still coming down really good, with temp dropping from 34 an hour ago to 32 now.

Love this... c-zone doing its job.

[The Swamp]

75mph?

 

We had a few big gusts.

[Kayla]

Wow, looks like things are really overachieving so far. Sitting at 31º here currently, much colder than I thought I would be at this point tonight with a light dusting so far.

If I was you guys with snow I wouldn't be here.

 

I'd be out playing in it and building a snow monster.

[FroYoBro]

I'm guessing our friends in Clark County are getting snow right now?

[luvssnow_spokane]

Totally dry out now. Lots of stars and clear skies truly overachieving tonight. I'm really enjoying this.

Is it really clear now??    

[Perturbed Member]

Just as that band hit, boom south wind. Temps climbed 2-3F. Rain snow mix now.

[HighlandExperience]

Clearing is a good thing right now. Need to dry out from all this wetness

[Kayla]

Latest 02z HRRR sure looks juicy and snowy for a lot of PDX peeps later tonight through the early morning hours.

Not necessarily good on the south side of a c-zone.
