[Cold Snap]

1985 coming up as an analog for this that’s kinda interesting.

[CliffMassYelledAtMe]

Looks like snow at the Hwy 18/I-90 interchange by Snoqualmie Highlands: 

[Norwood]

Unidentified white stuff falling at 363', Tualatin. 

[CliffMassYelledAtMe]

Possible snow on I90 near Eastgate? 

 

[bainbridgekid]

Lots of 32/33 degree readings in Enumclaw and almost certainly snowing. 
 

Also snowing and sticking on Tiger Mountain at 1,375 feet. I assume it’s snowing at your house @TT-SEA?

Clarification... its Issaquah Highlands and Snoqualmie Ridge.     I think that cam is near Snoqualmie Ridge.

Yes. I know where the cam is by road, but between Snoqualmie Ridge, Issaquah Highlands, Renton Highlands, Sammamish Highlands, Redmond Ridge, and whatever that neighborhood is up above North Bend, I get it all mixed up. Kind of like all the different hills in Kent, Auburn, and Puyallup.

Dumping at 1,600 feet on this cam between North Bend and Snoqualmie Pass.

Yeah... it all sounds similar for sure.   We are in the Uplands.   Just another way of saying elevated ground!

[Deweydog]

Had some SLOPPY flakes here for a few SECONDS.

So where does that magic two inches or so of snow on the EURO come from for PDX? 

The sky?

The odds are better than you might think.  NEVER underestimate what can happen when there's any Frazer outflow. 

Not much help from the Fraser outflow at this point. Still raining and 40F at Abbotsford despite a NE wind.  Hope has turned to snow in the last 1/2hr

The webcam for enumclaw looks kinda grainy but based on the temps being 32-33 looks like it’s snowing there. Looks like snow on under the streetlights. 

Impressive it's that cold there.  The temp has fallen almost a degree here in the last 20 minutes or so.  Currently 36.  The rain is getting a bit lumpier as well.

It appears the cold may arrive too late to help you much there.  I thought for sure this was going to work out up there.

Tomorrow and tomorrow night look better up here if there is any instability left over as the colder air slowly works it’s way in.  Could see some heavy bursts of snow. 

[Gradient Keeper]

Down to 35.4 with lots of snow mixing in now!

[Gradient Keeper]

35.2!

[snow_wizard]

7 degrees in Prince George with winds gusting to 36.  Yikes!

They dropped to 0 on Nov 6, 2017.  But this one will end up several degrees colder up there as the next few nights should have negative low temps

[Gradient Keeper]

Mackenzie, BC Temp 3, dp -13 NE winds gusting to 60mph. Nice arctic front.

[Requiem]

Snow is definitely sticking on most surfaces now so if any additional precip arrives I could see at least a coating by morning 

[ShawniganLake]

Lytton is 25F with a N wind gusting to 47mph so the Fraser outflow is trying to get its act together. 

[Cold Snap]

Only down to 36 with chunky rain still. I have a feeling the moisture might run out before it gets cold enough where I’m at.

34 degrees, chonky snow. We'll see if there's anything left in 5 hours when I get home. Hopefully temps drop another degree or so, and there's more of a chance to stick.

[TT-SEA]

Around 1/2 an inch of wet snow here.   ECMWF nailed the timing and extent of the precip.   

It shows another band moving into the Seattle area this afternoon and precip lingering around the south Sound this evening... but 925mb temps will be significantly warmer tonight than last night.   

 

[SouthHillFrosty]

37 and cloudy 

[TT-SEA]

It is worth mentioning that the ECMWF does show some significant snow in the Hood Canal area tonight with that persistent band of precip out there and cold air damming.     The map below is total snow from this morning through tomorrow morning and you can clearly see the cold air trapped against the Olympics later tonight.

Looks plenty cold up this way. -4C. Not as much precip as I’d hope for though
