January 2017 Observations and Model Discussion for the Pacific Northwest

[Kayla]

This is incredible. I haven't seen it snow this hard since my time in Truckee, CA. Has to be at least 2-3" per hour rate right now.

 

29º with 2" of new snow currently.

[TT-SEA]

Virga intensifying south of Puyallup.

 

Don't say I didn't warn you...

 

Looking at the regional loop... it appears we are at the northward extent of the deformation band now.

[Deweydog]

Jim Cantore is in the parking lot of Jollie's on 179th at I-5.

[Heavy Snow]

Heavy snow here in Gresham! Just saw a report of an inch accumulation at Happy Valley in 7 minutes.

More like 7 seconds...

This is a top 10 post of all time.

Yikes, made it even worse! Just turn your monitors over

Meaning?

 

Latest models show precip reaching further north later on.

Northern edge right over snowwizard

00z ups snow totals big time west side, I'd love to see the weather bell map

Not really.  

[Goducks09]

Bu-bu-bu-bu-but, Andy Carson said that only the higher elevations would likely be seeing snow.

Time to go get brother at airport....by the time I get back I expect PDX to be shut down!

Doesn't matter all that much at this point since it's actually occurring right now but here you go!

 

[Front Ranger]

The 0z 3km NAM did.

[EA_TTD]

1/4 mile visibility in Troutdale, +SN Temp 31 DP 28 Wind E-25G35. 

[TroutdaleWind]

Blizzard like conditions in Troutdale.

Loves It!!

[Goducks09]

 

 

Does it account for what is going on right now?

[SilverFallsAndrew]

Traffic cams show sticking snow in Salem now.

Everyone is going to get more than what is shown here. Hearing reports of over 2" in Gresham already.

 

3km NAM seems to have the best handle on things thus far.

It is snowing to the north of me and to the south of me. Weenie nightmare!

[SilverFallsAndrew]

If it makes you feels better it is still raining here at 1600'

The curse of Puyallup strikes again

[BLI snowman]

I think 6-10" is gonna be widespread, looking at the radar.

Where on earth in Tigard do you live?!  

[TT-SEA]

Does it account for what is going on right now?

Yes... 4 p.m. today through 10 p.m. tomorrow. Precips ends down the tomorrow morning though.

[FroYoBro]

Where on earth in Tigard do you live?!  

 

Right in the middle of the circle of hell I guess. 

[The Swamp]

The curse of Puyallup strikes again

Yeah, I really feel bad for him basically living in the mountains with 20" of snow on the ground.

 

Oh, a little rain.  Ha!  

[VancouverIslandSouth]

The Nanaimo-Parksville area got a nice dusting of "strait-effect" snow today. It was so low level that almost nothing showed up on the radar, yet many areas ended up with several inches of snow. All the while it was dry/windy a short distance north/south of the snow zone. That area has some nice geographic features that help in getting snow going into these events. As Arctic air crosses the Strait of Georgia it picks up moisture, but when it hits the island it dams up against the Vancouver Island range, winds slow and snow falls; because it's mostly immune to the outflow the snow sticks around on the trees for longer too. My brother took a picture of the start of the event:

Later in the day a little to the north of where that was taken it made for a great sunset scene; some of the low cloud still visible over the strait:

[TT-SEA]

9 out of 10 days with highs below freezing here... peak for the month has been 34.

 

Solid snow covering the ground the entire month.

 

7 of the 10 days have been dry.

 

Have not seen regular rain here since 12/27. And most of December was spent with solid snow cover.

 

35 inches of snow since December 4th.

 

I knew ENSO neutral was a good thing.

[Front Ranger]

Interesting watching that heavy blob get shredded by the Gorge wind on radar.

[SilverFallsAndrew]

I think 6-10" is gonna be widespread, looking at the radar.

Models show precip going another 12-16 hours, could be a good one.

[Jesse]

It is snowglobing here. I haven't even been on until now. Just out admiring it. Some of the heaviest snow I have seen in a very long time and fast accumulation. Huge flakes. Already about an inch on the ground.

[Jesse]

 

Many places in east county are already close to surpassing this.

[Laura]

Some very awesome 32 degree rain here in Oregon City.  I'm not sure i've ever seen it rain this hard! 

[Front Ranger]

I think 6-10" is gonna be widespread, looking at the radar.

 

Certainly possible, though if the 3km NAM is right, don't read too much into the radar as there should be a lull in the next few hours for most of Portland metro, followed by heavier snow again after midnight.

I was just asked to post it... made no comment about its validity.

Sorry, that wasn't meant to mean something rude. It was more giddy than anything.

We're currently getting at least inch per hour rates through Multnomah and Clark Counties, looks to continue for awhile.

[Jesse]

I just saw the radar. OMG!!!

 

It is snowing like crazy out there and it looks like it is not going to stop for a while.
