[T-Town]

Wow, very stormy with blustery south winds. Temp hanging tough at 42.

Me, watching others getting more snow, while I sit here in my 42* rain.....

Tim said the low is going east through Everett so it will be southerlies only for us south folks. Too bad. 

[Seattle]

LOL meanwhile it 43 at SEA. Euro was correct in the warmth of the southerlies, but not in the strength of the return of the northerlies.

Very impressive. Seems like tomorrow has been trending colder too.

Seems like models are back to showing a faster warmup but that's probably overdone. Mark Nelsen thinks we'll stay frozen until Christmas eve

[yellowstone]

32.2. On the top floor of my place looking out the north window and can literally see the wall of snow approaching!  

[Doinko]

GEM is crazy.

 

 

[TacomaWx]

Wow! South of green lake. 

[MossMan]

Absolutely epic!! 

[Cloud]

Winds at Seattle switched to W rather than S from earlier, it’s trying to go N now…. At shoreline it’s NE. The converging winds are around the north Seattle area.

It keeps the east metro frozen into Christmas eve.

I'm hoping flying into PDX on Sunday morning isn't a big problem

[Tyler Mode]

At least the warm up has lead to much more fun tracking the cold air's return!

I think you may be seeing snow at 10am…maybe even a little sooner. It’s moving south faster than I thought. 

[Art_Digbee]

16 degrees and the snow just ended... 

[jcmcgaffey]

Crazy change over. Went from heavy rain and almost all snow melted and 40deg to 31 in about 20min and heavy snow and everything covered including main roads. 

[yellowstone]

Boom! 32.0 all snow. Coming down hard!

[Ice_is_Everywhere]

Looking at the radar, I’m not sure I’ll see much before precip ends. Could be wrong, but I’m not holding my breath.

That'd be nothing less than catastrophic given the east winds out of the gorge

[Seattle]

It is 8:35 and like magic it is all (wet) snow, zero rain! The roommate stays home. I win, we all win! Now let the northerlies barrel on down south.

Low must be passing between here and Everett right now.   It is insanely nasty here... wind is whipping rain against the windows and the snow we got last night has liquified.    Definitely seems to be farther south than the ECMWF showed though based on observations in the Seattle/Everett area.

[MossMan]

21.5. Good god this is perfection!

My response was 100% sarcasm by the way just to poke Tim. I think both of us will see a switch and some snow.

I figured you would in a sweet spot there!    Awesome.  

[Cloud]

This is some dynamic stuff this morning. Battle zone right over Seattle.

Definitely seems like the backwash is going to be more significant. 

[Everleigh]

The wind is pretty gnarly here. For here, anyway, I don't tend to see those 40+mph gusts like some of yall! 30ish is generally the max I see. Still enough to take down trees and power lines though! 

[jcmcgaffey]

Reminds me of the switchover in Dec 2008. 

[Parrot]

Walked to work. Took most of an hour. Near blizzard like conditions. North winds really starting to rip. 10/10 would freeze my a** off again!

[yellowstone]

Accumulating fast and sticking to roads now. Heavy band moving in!  Such a great surprise after waking up at 5am to 36 degree rain.

Same here. Except we don’t have any snow to liquify. 

[Brennan]

21*f, 9” new.

[RentonHill]

South wind just died here. Temp up to 41.4 and heavy precip. 

[Hawksfan2008]

Never thought of this! Looks to be much more accurate than using the radar depiction. 

[Blizzard777]

There ya go

Federal Way! 
Good news I’m getting my windshield replaced now so storm did not hamper this appointment. Thankful 

[jcmcgaffey]

Looks to be short lived though as the back edge of this intense precip is just passing the Olympics. Should drop a couple inches on top of the wet slush we had before drying out. 

[Seattle]

This is not even 7 minutes of accumulation. It’s coming down hard! 32.7 now.

GFS starts our overunning event with some light snow

 

12z GFS is less aggressive with the warmup. 00z last night had most of PDX Metro above freezing by Friday 10am. The 12z GFS now has PDX still in the teens at the same time. Good to see as we get closer to the event.

As expected the ECMWF was pretty ridiculous on the south winds this morning.  We'll see if this translates to a surprise for the Seattle area.

It has changed back to snow here and it is absolutely dumping and quickly accumulating.

GEM is less aggressive too with the warmup

If the rain/snow line stalls out just north of us..
