December 2019 Weather Discussion for the PNW

[Jesse]

12z Euro definitely a little wetter than last night’s run at least.

[TacomaWaWx]

Breezy and rainy in Tacoma.

[TacomaWaWx]

First real wind event of the season underway fairly weak one however. Hood canal bridge is closed currently due to wind as well. Should easily be the strongest southerly wind event so far this season.

[Prairiedog]

For sure. 2007 was the last time there was regional Arctic air in January. 2008, 2009, 2012, 2013, and 2017 all got close but couldn't quite get there.

It may not have been arctic in origins per se  but when my small river freezes over, two mornings of 8f and several days with highs in the low to mid 20's, the cold was great.  I had snow on the ground for almost a week.  At 310ft not that far from PDX, I'll take that any day.  It sure felt arctic.  I don't remember much or any Gorge outflow here (maybe some out towards Gresham?).  I was really happy with that level of cold. 

[SilverFallsAndrew]

I didn't think the EURO was a total disaster. Sure not as good as the 12z GFS, but we all know that has no chance of happening anyways.

This is true.    Wind is howling on the canal this morning!

[ShawniganLake]

This is just sad...

 

 

I've triple checked this because I can't believe it's true but according to NWS CF6 data: #Seattle has not recorded a gust over 25 mph since Oct. 25. And 28 mph stands as our peak gust this autumn/winter April 6 was last time Seattle hit 30 mph gust. #wawx— Scott Sistek (@ScottSKOMO) December 31, 2019

One of the most dead boring nov/dec I can remember. I’ve only gusted above 10mph 2 days this month.

 

Euro has some lowland snow

[Jesse]

This is true.    Wind is howling on the canal this morning!

Welcome! Cool to see some representation from that part of the region.

I assume you're talking about 2017? There was definitely Arctic outflow through the Gorge for the Portland area, but I was talking about regional events.

Definitely a step in the right direction.

[TacomaWaWx]

Pretty breezy here but not crazy. Think most of the Puget sound region is supposed to have peak wind gusts this evening. Regional fireworks shows are in jeapordy.

[TacomaWaWx]

Definitely a step in the right direction.

Even if we don't end up having snow and cold atleast were having a legit active pattern and not split flow. Plenty of mountain snow and rain finally. This pattern very well could deliver snow and cold however with a few minor tweaks to what is being shown.

[GHweatherChris]

Holy heavy rain!

[Jesse]

Rain still looks a ways off for Portland judging by radar.

[MR.SNOWMIZER]

Pretty neat to be out of cell range then come to town and see the massive model improvement

[TacomaWaWx]

Holy heavy rain!

some pretty heavy radar returns in the SW interior. Quilayute is expected to break their daily rainfall record today as well. Definitely a decent rain event for those not in the rain shadow.Rain shadow was keeping Tacoma dry for awhile but it's not doing a good job at keeping us dry anymore.

Always the best feeling. Has happened after several road trips and camping trips for me.

[TT-SEA]

12Z EPS at day 10...

 

[TT-SEA]

12Z EPS at day 12...

 

[FroYoBro]

Looks wet north of us right now. Just like earlier this month. 

[TT-SEA]

12Z EPS 10-15 day mean:

 

[Deweydog]

SCORE!

[Jesse]

Looks wet north of us right now. Just like earlier this month.

 

At least the band doesn’t look to be as stationary this time.

[SilverFallsAndrew]

Chilly

[MossMan]

Stopped by the lake house a few hours ago, was quite stormy...LOVE IT! Here at home lots of rain still going on, up to .40” on the day. Winter is here!!

[GHweatherChris]

1.9" on the day now.

[VancouverIslandSouth]

Today might bump us to an average December rainfall. Looks a little snowy in the BC interior (the passes look more like ski slopes than roads):

 

 

 

[Front Ranger]

Going to end up a pretty wet December for most of Western WA.

That looks incredible. 

[SilverFallsAndrew]

Meanwhile another dry month down here. 

[ShawniganLake]

PHIL!

[ShawniganLake]

Meanwhile another dry month down here.

We’re gonna need a couple more inches today to get to average for December

[SilverFallsAndrew]

Hit 50 a little while ago. Currently 49 and cloudy with breezy conditions. 

 

Got the sheep moved down to the winter pasture this morning. Ready for whatever January brings. 

[TacomaWaWx]

Going to end up a pretty wet December for most of Western WA.

Western WA got the majority of the rainfall in October too while BC and OR missed out on some of the heavier totals. Then this month the same thing happened.

[TacomaWaWx]

30 mph SW gusts in Tacoma and 47 here. 0.16" today.

[Front Ranger]

PHIL!

 

Ha, actually wasn't even thinking of him. Just crazy how much wetter December was than November...6-7x as much rain some places.

[Front Ranger]

2019 and 2018 will go down as the driest back to back years on record for PDX. In fact, first time they've seen under 30" two years in a row.

That’s interesting. How far back do records go?

[Jesse]

Nearly 80 years at the airport.

[Jesse]

I will say, I will take the weather turning a corner to more active with some potential down the road at the end of December as opposed to the end of January.
