February 2014 in the PNW

[AnthonyC]

Quite an amazing few days for PDX.  And SEA gets completely screwed.

 

I think I'm officially ready for Spring now. :0

[Dadio]

Latest IR loop. Notice, one, how much of the storm is still offshore. Surface low way to our S. Deformation band to its N-NE where we'll see heaviest snowfall. But what about those lows forming to the N-NW of today's storm. I have a hunch that these lows are spinning up and travelling along the stationary boundary over western Oregon, thus not allowing a Pacific system to drive in from the W-SW directly and ending our cold air. A *HUNCH* here is that we *MAY* see another system later Saturday that could be significant and may not warm us up as much as models are showing. NWS has hinted at this as well in past several AFDs.

Oh my.... I'm almost speechless at the idea.

[Deweydog]

You are just starting to get into the action now.      I am thinking a DZ is going to pummel your area later.  

 

Yeah, it'll be close I think.  We were right on the edge of the sweet spot yesterday, but the synoptics for this system are quite a bit different.  Just gonna have to let it play out.

Tons of rain first.

 

The ECMWF has the jet plowing into us for the next week starting on Monday.

Your kids are probably old enough now that they will remember this one for a long time!

This would be the intensity of the snow per 3 hr totals ... I only did it to 3" but here is the general outline ...

And this is only if that batch of moisture moves northeast like the satellite shows, which is against most models.

 

Upper Left - 4pm

 

Upper Right - 7pm

 

Lower Left - 10pm

 

Lower Right - 1am

 

Looks like the sound does have snowfall, the most centering from Seattle at the north end ... and Olypmia at the south end ... of course the heaviest tonight at The Dalles ...Other images I did not shown shows the same over the Southern Sound areas at 4am so i'd assume if that happened the area would get 1-2" of snow overnight ...

 

The scale for the colors -

 

Magenta - 3" in a three hour period

Dark Blue - 2" in a three hour period

Light Blue - 1" in a Three hour period

Green - 0.1 - 0.5" in a three hour period

 

You can add it up from there ...

Based on the current radar things look to be a bit ahead of schedule but overall this is a very good indicator. Nice!

[MossMan]

Just saw a pic on FB of Ice flows on the White River near Auburn

 

D**n

Driving past the Stilly I noticed ice chunks flowing down that river as well!

[TT-SEA]

Dewpoint in Bellingham is dropping... back down to 8.

 

Northerly flow picking up across the Sound.   

 

Offshore gradients from the east are much lighter today.     Yesterday the SEA-EAT gradient was -10.1 and today its at -2.9 so the east wind is non-existent out here today.   

 

Must be related to the different dynamics Dewey mentioned with today's system.

[luminen]

25" snow depth at EUG being reported. 

[GHweatherChris]

Northward progression of the moisture has not slowed down at all per radar.

[TT-SEA]

25" snow depth at EUG being reported. 

 

 

This is old-school epic for Eugene.    First the incredible drought and heat... and now the most incredible winter possible.   

[MossMan]

Pack up the babies and grab the old ladies! lets go!!

ROAD TRIP!

[Jesse]

One thing I know. When it is 23, DP 19 in Eugene with a NNE wind, we are pretty far from a warm up out here.

[MR.SNOWMIZER]

Seattle nws talking about some new things going on of our coast. There thinking some snow is looking like it will happen tonight south of seattle.

[Dadio]

25" snow depth at EUG being reported. 

Yehaw! Rock and roll. Now that is getting to some serious snow.

[TT-SEA]

Northward progression of the moisture has not slowed down at all per radar.

 

Looking at the coastal radar... I am now interested.    Looks like the fun is just rolling right towards you.

I've been thinking about the same possibility.

[MR.SNOWMIZER]

25" snow depth at EUG being reported. 

wtf

[BLI snowman]

25" snow depth at EUG being reported. 

 

Gotta be an error, reports have them at 7-8" now. You're down there, is it 8" or 25"?

[MR.SNOWMIZER]

I've been thinking about the same possibility.

It has happened many times in the past.

[GHweatherChris]

I have been talking about it all day.  

 

This thing is ripe for surprises not shown in the models.

[TT-SEA]

One thing I know. When it is 23, DP 19 in Eugene with a NNE wind, we are pretty far from a warm up out here.

 

I say that about Hoquiam during our events.   

 

That is pretty insane.   

 

Of course PDX could be 45, DP 42 and you could still be in the deep freeze out there with this set-up!

[MossMan]

Looks like I have hit my high of 33, back down to 32 now under mostly clear skies.

[Deweydog]

Your kids are probably old enough now that they will remember this one for a long time!   

 

Definitely.  My son is starting to act a lot like I did back during some of the snows of my youth.  I think he's gonna be another weenie.  I quizzed him last night about December 2008 and I was impressed with how many details he could recall.

I'm liking how this is working out. We're keeping the cold longer. A bit of a reinforcing wind out of the north going on and now moisture is still coming up from the south. Sounds like a party to me.

[luvssnow_spokane]

Looking at the coastal radar... I am now interested.    Looks like the fun is just rolling right towards you.   

I have been watching this like a hawk today. Progression has been very favorable for us. I am starting to get excited about actually getting 2 inches or more tonight.

Northward surprises are very common.

I do not use the models when things are less than 24 hours out. I primarily use IR and Radar to track this stuff. It is often the better indicator than any model. 

[Weather101]

Keep it rolling north !

Olympia always seems to do pretty well.

That is true... with the re-establishment of the north winds through the Sound it could set up some kind of convergence with the moisture streaming in from the south.

[MR.SNOWMIZER]

So have I.

[luvssnow_spokane]

Centralia could have snow within the hour at the rate it is progressing

[HighlandExperience]

That is true... with the re-establishment of the north winds through the Sound it could set up some kind of convergence with the moisture streaming in from the south.

 

Perhaps there will be an explosion of snow tonight over the central sound.   C'mon we need something!

[TT-SEA]

Centralia could have snow within the hour at the rate it is progressing

 

Still sunny out here.   

 

But that is about to end.

[MR.SNOWMIZER]

Latest sat loop sure looks good.

[GHweatherChris]

So have I.

Yes you have.

 

We don't need models to lie to us.

Two hrs ago my dew point was up to 21, but I just checked it again and it is down to 13!

[luvssnow_spokane]

Still sunny out here.

Cloudy here... and moving your way... AND no it is not swamp gas!

[HighlandExperience]

We need SnowWiz on here tonight.
