18Z ECMWF a little warmer again with the temp spike tomorrow morning. 

To lay out timing... this is snow through 7 a.m.  and the projected temps at that time.

 

With how the Radar looks right now I feel like those totals will definitely be higher especially south of Everett.

[Ice_is_Everywhere]

It might be hard to sleep tonight

Why is the EURO such an outlier at this point? 

[yellowstone]

Light snow. Starting to accumulate. The 18z Euro says I’ll get less than half an inch. At this rate we’re about an hour from it officially busting…

[SilverFallsAndrew]

Well if it makes you feel better TWL and I are having a pity party on FB messenger about January being off the table.

[TT-SEA]

Arctic front snow from Tuesday evening through Wednesday...

[Ice_is_Everywhere]

Just curious, when does the Euro have precip starting?

Because it wants to deliver a snowbustcity.

God, the Euro is still verifying +8F in the strait. Honestly I am just as disappointed as I am excited; this is supposed to be the king! Must be very unnerving for the Sandpoint mets to watch obs go against the grain and the normally "safe" path of just trusting the Euro. But this is of course a very tenuous situation... I think it deserves some slack.

And their WSW shows some real maturity there--nice to go with observations and their gut instinct instead of the moderate solution. I really respect it, even if it busts tonight. The mark of a good forecaster is communicating when a very large threat exists, even if it means risking your reputation in the event it flops. This is a brand of courage that I wish I saw more often. Great on them!

Was just thinking something similar. The EURO made me nervous but it’s time to trust the experts. No model is perfect or they wouldn’t have jobs…let’s go snow!

I was just noticing that I can't see Mt Si now so visibility is dropping here.   Don't see it accumulating on the bare driveway yet though.   

[Jean Ralphios Ghost]

Is there a specific reason why temp maps have colder temps as red and warmer temps as blue?  It just doesn't seem intuitive.

About now.

Anything falling there? Radar says snow over me. Nothing lol. I’m not far from you really. From the mountain 15 mins behind my house you can see rattle snake ledge and the green river watershed.

Maybe if we cancel it hard enough it will come back to us?!

[SouthHillFrosty]

Light snow currently 

[jcmcgaffey]

Snowing pretty good now and covering ground and cars. Looks like heavier stuff coming in soon.

Dear Washingtonians,

May the most benevolent outcome occur on this chilly December night. Let the snow pile high, and make sure to post LOTS of pictures, so we can be in the moment with you.

 

Sincerely, your brothers from Oregon

I am going to beat those amounts in the next hour or two here at this snow rate. 

[TacomaWx]

Euros definitely an outlier compared to most solutions. Have a hard time believing it’s going to moderate that quickly so far north.

I don't see snowflakes but it also looks hazy in the distance.   My son was just outside and called it snizzle.

[jcmcgaffey]

Temp dropped to 31 here and dew point still in the 20s. This should be good if the precip continues. 

[Perturbed Member]

18z euro

Boom, colder 850s and starts as snow in PDX with -1c up there

 

[Deweydog]

The Euro clearly has caught whatever the GFS had last week. Wash your hands and practice social distancing!

This is the very first time the euro has hinted at some snow going into the overrunning here in PDX.

yeah after this present event winter is officially over

[Sandy rocks]

The winds are starting to shift to the east now in Sandy. I was in Gresham and it is six degrees warmer in there. Troutdale is also showing a shift.

I'm rooting hard for you guys.  With all the effort you folks put in with tracking this stuff, it's the least mother nature could do.

[Meatyorologist]

Those little dots of ice that look like tiny snowflakes are called snow pellets -- they form when supercooled water coats snowflakes and uses them as condensation nuclei to freeze! They form when there is a lot of moisture in the column and when snowfall is light.

Had a brief bout of that here, but have now transitioned to a steady light, normal snowfall. 31/29 here and holding steady, maybe dropping a tad. Other stations are cooling slightly. Slush is refreezing slowly.

OLM down to 35... you know you have a problem when you celebrate a 1-degree drop in temp.

34!!!

Sounds like something I do when I sneeze on my wife.

A wetter run as well-- more moisture to work with.

[Seattle]

I am quite surprised at the rate which this snow equivalent of heavy drizzle is accumulating. Already a thin layer recovering roofs, cars, grass, and anything else elevated. I don't have a thermometer, but it's clearly below 32.

I hope so. I am right on the line between 1in and 10in. However, my location has been blessed this year so far… gotta continue the trend!

I’m still having those pellets here. Still 33/31 dp.

[FroYoBro]

All rain here.
