I'm thinking the NWS should issue a winter weather advisory for the Central Puget Sound area tonight.  I'm also puzzled about how they have no mention of possible strong east winds in the EPSL forecast beginning Wednesday night.

Do you actually think there’s going to be enough to do that? I’d be fine if it was even for 1-2”. I feel like there won’t be more than that if that.

I'd say strong, but not insane with it being cross-Cascade vs. just a gap wind.  Then of course when it ices up we get no readings...then if the power goes out...

That would be enough for a special weather statement.

The freezing rain is coming! Get ready while you can!

Some pictures from my snow walk today through Sehome Hill and downtown.

Thanks. This would be very bad

Over 3" of ice! That is approaching 1996 levels.

[SilverFallsAndrew]

There was actually a fairly significant icing event in Marion and Polk counties on December 20-21, 2008. I would say it was the 3rd most significant ZR event in the Salem area since 1990.

It came after most of the area had gotten 3-6” of snow and sleet on the 20th and a day before the mid valley was battered by 6-10” of snow on the 22nd.

This frozen drizzle is starting to turn the side roads white.

Christmas could be near 80 down in Southern California. 

My wife grew up in Southern California, and to this day she swears she always went swimming on her birthday (December 27th).

Still the best winter event of my lifetime. I lived in Yamhill County back then.

light snow flurries in the Puyallup Valley

i hate to see ice storms

the last one i can remember here was nasty.  trees came down, power was out, it was really bad

praying we don't see that again any time soon and certainly not before Christmas weekend

[Cold Snap]

Lightly snowing again! Currently 27.

Sustained 58-67mph, gusts over 85+ 

[awright-31]

Does anyone know how much ice accumulation OLM received in Jan 2012 or where I could find that info?

[Terreboner]

Hey guys!!  You see that CZ gaining strength along Hwy 2?  Looks like it is filling in back-building towards Everett or just south.

I'm skeptical of 85+ due to the downslope nature of the event but I'd imagine 70+ is a good bet

Definitely going to be that strong if you're downtown between a couple buildings. BRRRRRR!!!!!

[Terreboner]

Looks like radar is about to fill in around the sound very well.  South and north.

[MossMan]

They are already talking about the possible widespread ice storm that could be coming on Komo radio…That should get the panic level up a notch or two! 

[GHweatherChris]

Pretty uneventful day here today.

[Dave]

On Dec 14th 2016, Eugene had a terrible ice storm. Ice at least over 1.5". Somehow, I never lost power but some people in the hills lost it for 2+ weeks. At least there was very little wind. Some parks were closed for over a year. Anyone that had a tree on their property had some cleanup to do or major damage. 

[Requiem]

It's the 40+ mph wind in addition to the .25-.50 inches of ice that concerns me the most for this system

[Cloud]

Believe it or not but the HRRR actually picked up on the convergence setup near Gold Bar for several runs this morning and afternoon for around this time. The only difference was that it extended farther west into Everett than what's current shown. Then for some odd reason it completely went away with it the last few runs. 

Really odd model. 

[SouthHillFrosty]

[Frontal Snowsquall]

Both the 00z HRRR and NAM show moisture starting as snow for PDX Metro Thursday afternoon. The initial band will be key in getting snow accumulations before changing over to sleet.

 

[Front Ranger]

CZ starting to fire up in along east King/Snohomish county line.

[MossMan]

26/20 on the day. 
Currently 24.8 and very light snow. 
7” of snow on the ground.

Been below freezing since early afternoon on Sunday.

Maybe I just have a dirty mind, but that Freezing rain outline is naughty!!!

[Seattle]

Will tomorrow have a midnight high for Seattle (and also PDX too), with temps continuing to fall throughout the day?

[TT-SEA]

I thought the NAM was usually too cold?  The 00Z run shows this for Saturday morning... would be a blessing if it's raining.

The WRF is forecasting 75mph+ gusts in east Portland Thursday night

 

That’s insane. I’m going to get hammered!

It also shows PDX dropping 10 degrees in 3 hrs when the east wind starts and  then advects us down to 13 degrees. Not sure how it's so aggressive with that and then mixes us out so quickly

I don't think any models are great at handling the established cold-- at face value we'd likely warm up Saturday afternoon and not nearly that quickly 

[Terreboner]

Breaking news!!!!

The little Vort-Max near Vancouver Island has been deemed a "Bomb Cyclone!!!".  Grab the women and children, pets, prized liquor collection, weed stash, cocaine jar, even your mother in law, and head for the hills now!!!!  This is getting serious.

The NAM is awful. 

[Cloud]

The 00z regional GEM initializes to pretty much what the other models showed as well. 

Snow develops around 10 tonight and going for several hours.

Did you have a conference call with Environment Canada?
