Yep...

 

I'd almost say it's close to impossible not to have any snow accumulation with this on the kitsap peninsula and other places.

Doubt it.   Looks pretty disorganized and splitty.  

I’ll try to let y’all know when it starts.

[LowerGarfield]

It is 5F degrees now and I just got back from taking the trash out to the street with mutiple layers. Anyone else remember that $5 footlong promo from like 10-15 years ago? Esp with Godzilla.

We can't buy a good ol fashioned overrunning event any more, one that cripples all of the westside with inches of snow for half a day before subsiding, those were the days.  And only less than 10 years ago.

What a waste of beautiful cold. 

[MossMan]

Might be a fake and expensive fire but it does feel good and cozy while 11 degrees, dog on lap, and watching White Christmas! 

[LowerGarfield]

We're staying at home this week because we are all sick. Son has been sick since Saturday and spouse and I have succumbed. Even one of our cats is sick. But if nothing else it made my wife's decision not to see her family in Clark Co easier. Ice looks bad there. Chance of ice at my location on Saturday.

[Doinko]

PDX is 30/14 right now. Thankfully it looks like we won't get a midnight high above 30. Should be our first high below 30 degrees since 2017 and potentially our coldest since 2014

[HuskyMaestro]

KIRO7 is laughable for rating an upcoming ice storm a “2” on their storm scale from 1 to 5. If the 0.5” of ice verifies for the South Sound, that’s some widespread devastation on the utilities, trees, and roadways just waiting to happen. Really hope we’ve learned from 2012..

Yeah, seems like the local news outlets and the NWS are ignoring output from most models at this point for ice. I sure hope they’re right…

[FroYoBro]

26 here with an east wind breeze. Nothing very strong yet. 30 at pdx still

[MikeInEverett]

If we get enough precip early on, I’m thinking we’ll see a pretty good amount of snow, like 2-4” north of Seattle. Just throwing that out there based off previous overrunning events like this.

[Winterdog]

Looking at the satellite loop it's a good bet that clouds will be rolling in Western Washington before it gets too late.  I'm guessing the minimums are going to be a bit higher than we would have liked.  Still impressive but not as low as a totally clear night with snow on the ground would have delivered.  17F here under clear skies.

Yeah those dug a lot more to the SW over NorCal. This airmass is a lot more like 1983 where the arctic airmass is just north and east of you.

I was to young to remember that one. 

[SilverFallsAndrew]

Low clouds have rolled back in. 

[Perturbed Member]

HIO has caught up and passed PDX in cooling now. Down to 27. Not a ton of east wind out here yet but probably getting plenty of radiational cooling to drive some of this. 

PDX stuck at 30F but DP is down to 12F at least. 

 

 

[Terreboner]

Looks like the cold air is retreating already, we just went from 13.7 to 13.8.  I am officially worried.

I thought it was supposed to be cold guys! My station is reading a balmy 18° C....no wait thats an F next to it, wonder what that means

Unfortunately the only lesson we can learn is ice storms suck. Not much can be done to prevent the problems they create.

Comparing 850mb data for 18z initialization vs 12z forecast as well as trend at 4PM today between 18z and 12z. 

We can see the euro seems to be running a bit warm at 850mb and the observed vs predicted values were too warm by about +2c at 2 PM and 5 PM at PDX as per SPC mesoanalysis. It may not end up mattering tomorrow but probably good to keep an eye on. 

It may not mean a whole lot for Friday's precip type, but it does have quite the implication for our temperatures tonight. A deeper, more entrenched airmass means less clouds, deeper boundary layer, and less thermal energy in the lower atmosphere. Those differences compound and could allow for an extra few degrees of cooling.

I know I'm being a total weenie dork about the low temperatures tonight, but these kinds of rare instances of overperforming cold are growing even more rare by the year. And they are surrounded by an ever larger mass of heat records. I am relishing in this rare, precious win. Especially since the kind if cold potential tonight stacks big, right along our very best cold snaps even decades ago. That is something we haven't really seen in 12 years now, arguably since 1990.

I missed the happenings...any chance of a sub-freezing high for you still? I hope so, but I'm probably poking a sore wound

[TigerWoodsLibido]

Freezing line is now between Salem and Albany.

[Doinko]

The WRF isn't backing down on wind. It's still showing 55mph gusts back home Thursday morning.

Will probably be about 34 by daybreak.

Now I see why PDX has less ZR than Salem. They get a ton of sleet! 

[Terreboner]

If this was the middle of summer it would just be another high pressure system holding off a Pacific low pressure system.  But...since it is a very cold high pressure in mid/late December we are rooting, rooting for it!!!

 

Pretty fun to watch the incoming clouds get obliterated and watch the low level flow win out!!  This sets the stage guys, we want that thing to stay offshore as long as possible while this air feeds in.

[MossMan]

60 degree swing between inside and outside!

W7ENK from the old Fox 12 blog in Portland had a saying something along the lines of a completely dry arctic blast being like uncorking a vintage bottle of Dom Perignon and pouring it down the toilet.

Been a while since my last completely dry wintertime blast and I really do not miss such things.

[MWG]

Got you all beat 43F

Maybe some cold core thunderstorms for the coast Saturday afternoon?

Yeah the “flash freeze” mid day yesterday was pretty wild. It was bitter cold and tomorrow will be even colder. One of the more impressive air masses in my lifetime.

[MR.SNOWMIZER]

Rgem shows an extended period of snowfall from SeaTac north. 

[SilverFallsAndrew]

19 at Sea Tac.

Dry blasts are the most worthless things ever. I still have nightmares about December 2009

I was kind of surprised to look back and remember that we hit 17 last year, and 13 in 2019, and 19 in 2017, 22 in Dec 2016, 16 in 2014....even though this air mass is 10x more impactful for the rest of the US and maybe we get some decent low highs out of it...we've had some pretty cold days the last 10 years. Yes the highs were never that impressive, and yes my house isnt Seatac and will always be a little colder...but it can and does get cold here every couple years. Wish I kept a journal about all of those "events" to look back on and eventually save. Especially now that i've taken up following the lead-ups closely. Would be cool reading for my family or children to go through later in life. A good chance for grandchildren to better understand "who I really was" at this age. OR I could just leave them my login and password here and that would work. 

 

maybe time to put the prosecco down lolz
