December 2015 in the Pacific Northwest

[snow_wizard]

Especially with all the snow cover from the west side foothills all the way east.

 

Indeed.  That heavy snow cover will likely play a role.

[snow_wizard]

It's typically imperative things turn over at least once over there early on if you want something really special and homegrown. December 2005 and so on... Not sure if that's in the cards. WRF does show things clearing out over there as the cut off comes into play but I consider that a little suspect.

 

Good point.  I would really like to see this one go all the way, but a few things have to go right.

[snow_wizard]

Yeah, it's occurring a good two weeks ahead of schedule. Some very odd s**t ongoing right now, actually.

 

The Cascades getting epic snowfall the past two weeks with a Nino of this magnitude certainly shows something is whacked.  The few days of very high SOI last week also caught my eye.  In general SOI has been much higher than would normally be seen with such warm ENSO SSTs.

Quite an epic cold pool on the GFS/WRF. WRF shows strong east wind through day 7-8 and probably longer looking at the overall pattern. Wind Advisory for gusts 45-55mph east of I-205 likely. GFS shows possible pattern change after day 10. 00z GEM gives PDX an ice storm day 9-10. Looks like fun times ahead.

It's 27 here right now.

[MossMan]

28 currently here. Will be nice to transition to frozen ground for a while, my yard was getting very squishy. I should be able to mow the entire 2 acres possibly by the end of the weekend as long as the daytime temp gets to about 35 degrees.

You will probably be the only one in WA mowing this weekend.

We here in Southern BC just felt a big quake! Did you guys feel it?

4.8 near Victoria.

[bainbridgekid]

Getting lots of reports from friends of a fairly significant earthquake in Bellingham.

 

Preliminary report is 4.8 5 miles North of Victoria.

[Bryant]

Definitely got my heart pounding

This is the only one I have ever felt. It was a bumpy ride. The windows were shaking and my couch I was sitting on was jumping up and down.

[Jesse]

In bigger news, PDX just hit 32 for the first time this month.

So close.

I was really crying for you for a while.

[Poulsbo Snowman]

Basin cold pool off to a rocking start... Near 30 around the Tri Cities. That's below zero celsius.

 

Also below 275 Kelvin.

[MossMan]

Didn't feel the earthquake but had fallen asleep before it happened so I have no idea if I would have felt it or not. Anyway currently 27 degrees and frosty!

[TT-SEA]

25 here with a dewpoint of 20... snow is sparkling under the lights.

[Parksvillewx]

Didn't feel the quake, was sleeping but...its currently snowing here oddly enough. Light coating of white on lawns and cars.

[TT-SEA]

Crystal clear here... going to be a very bright sunny day.

 

06Z GFS brings in rain by the middle of the next week.   And it would be rain with 850mb temps above +3C.   That would break up the inversion.

[Tyler Mode]

27.5 here with fog.  Roads are a sheet of ice from all of the rain yesterday.

[TT-SEA]

This ridging pattern is being shortened in the models.   The 12Z GFS actually shows rain in places already on Sunday.

Victoria BC where the earthquake occurred close by had the temp rise from 30 F to 36 F right around midnight when the quake happend, then dropped right after to 28 F all under clear skies. Hours before it was right around freezing till the Earthquake.

 

1:00am Mainly Clear. (28F )

12Z GFS shows what looks like a warm, wet pattern getting close by Monday... just 5 days away.  Starting to think our dry period is going to be very short-lived.

Got down to 23 last night.

That's freezing rain or snow for the Portland area.

[TT-SEA]

Beautiful morning...

Impossible for snow... 850mb temps are WAY too warm.    Might be freezing rain or drizzle if cold air is trapped at the surface near the Gorge.

It will be interesting if we go straight back into a wet pattern.

[luminen]

I felt the quake as I was still wide awake. It was pretty short but definitely felt bigger than a M4.8. 

 

Got down to 23F this morning.

Does seem like it will turn super wet... most of the energy will likely end up diving towards CA.    I think the next couple months will be quite wet down there with the Nino finally delivering rain/snow for them.

 

But an endless building inversion does not seem likely now.   Occasionally wet up here is a good bet later next week.

As you say, 12z GFS opens up the storm train door once again early next week lasting through the run. Still doesn't look Nino'ish to me.

I just think it will end up more splitty and focused on CA than the 12Z GFS shows.

Looks pretty darn nino-ish.

[Weather101]

El Nino?

12Z Canadian sends all the energy and precip down through CA all the way until the end of the run with split flow up here.     The definition of an El Nino pattern.

Yea, my wife just called me and said it was snowing lightly on her way to work.  Nothing falling here at the house though.  You could see some light snow flurries forming over the Strait of Georgia Late last evening.

Well that makes no sense...

Mote likely due to passing cloud cover rather than anything related to an earthquake.
