December 2019 Weather Discussion for the PNW

[Deweydog]

Got my first real bout of frostbite on my fingers this week! I’ve seen colors and swelling that I didn’t think was possible on ones hand. Not recommended.

Cautionary tale for all of us westsiders come MLK...

Word of advice with the impending #2020polarvortex. Tape hand warmers around the inside of you wrists to pump warm blood to your fingers. Thick mittens are not enough!!

Yeah I learned a valuable lesson during a snowmobile outing over in Mazama.

All of the sudden another amplified block is showing up in the models.

Sliding east as usual. Our access to Arctic air continues to be cut off year after year.

Not ideal for the PNW, obviously, but still a rather amplified block that has started to show up. And wasn't there a few runs ago. 

 

Lots of time for things to change, just noting that development.

I think the euro has been showing something like that for 3 or 4 days now.

[Gradient Keeper]

Not many changes other than Day 6-7 the BC trough almost managed to dump cold air into Eastern Washington, but the highly amplified progressive ridge moving inland kills that idea. Like I mentioned earlier let's see how things look in 3-4 days once that Aleutian low/trough is insight within Day 4-5. Perhaps then we may see more notable changes. 00z GEM at Day 4-5 has a deeper, more compact low well off the southern Oregon Coast. The only results are increasing east winds again. The low weakens as it moves closer to us. Yawn. Onto the 00z GEFS, then EURO....

Sorta, but not connecting the Arctic block as well to the east Pacific block.

[Gradient Keeper]

00z GEFS - Portland at Day 4-5 is a near torch-fest mean temp up to +7.5c!

This was from the 28th. Looks pretty blocky

 

[Jesse]

At least the 00z GFS has a couple decent rainstorms.

 

But yeah, looks like it’s shaping up to be a pretty mild first 7-10 days of December.

December opens up mild.

 

[Deweydog]

Eurotyme!

[MossMan]

I doubt much will change in the next 14 years. She’s an emotional train wreck.

I have one of those as well!

 

Anyway it is currently 36 degrees.

Really is amazing how their personality traits at a very young age carry right through to adulthood.

Mill/zillennials... its happening! Although I believe it is mostly from the parenting, not from all parents but still ...

[VancouverIslandSouth]

Looks like I didn't miss much while I was gone, felt cold but I doubt Victoria had any snow. The weather in Asia was interesting, big swings from humid 70s to cold dry 40s in Japan but mostly dry the whole time. Thailand was hot with varying levels of humidity. Taiwan was warm/drizzly, seems to be the default pattern in northern Taiwan under NE flow.

[TT-SEA]

Mountain snow by day 10?   Maybe this time it will hold?

00z EURO looks a bit more active in the long range. Here's the total rainfall and snowfall through the next 10 days.

Is anything on Mt Hood open? Was there ever a year where nothing opened?

[Gradient Keeper]

00z EPS Day 7-10. Quite promising following the Op run. Let's see timing move ahead inside Day 6-7 though.

Timberline and Meadows are partially operating. I dont think that's ever happened before but we've gotten close a couple times this decade.

That’s an excellent pattern for wave driving/long term blocking (oversimplified/acronym-free way to describe it).

 

Play the long game.

[SilverFallsAndrew]

Chilly morning. 

[TT-SEA]

Chilly morning.

 

Feels mild compared to recent mornings... 40 here and cloudy.

[Tyler Mode]

Most of Clark County had an area of moderate rain move over last night between 9-11 and lay down a lot of water...and it's 28 this morning.  Lots of accidents.

[Farmboy]

It feels like the theme for this winter in the PNW should be: 'anticlimactic'...

[FroYoBro]

Feels mild compared to recent mornings... 40 here and cloudy.

 

A lot of the Willamette valley is back below freezing this morning. 

[TT-SEA]

So it appears. Must have cleared off down there.

[Tyler Mode]

Cool ice patterns this morning!  Even formed into my watermark on the bottom right!

[Jesse]

Icy and 29 here this morning.

[FroYoBro]

Wow, some roads are really icy out there this morning. A car spun and did a 180 right in front of me and I barely avoided hitting them.

[TacomaWaWx]

Got down to 35 this morning, currently 37. Had a 43/37 day yesterday with 0.04” of rain, another 0.01” of rain this morning too.

[TacomaWaWx]

We will see what the 12z shows, but the 06z wasn’t very wet or active really through day 10. We’ve gotta get a more active mountain snow pattern going to open up all the resorts and start building snowpack. Hopefully Mother Nature starts cooperating.

Glad you're ok.
