Radar showing precip over me so I did a streetlight check. Nothing falling yet.

Same

It's been snowing pretty much all day here but nothing has stuck, temps have been around 34 and it's just too mild with everything melting on contact for hours!

No complaints though, got a 14" dump just before Christmas and 8" yesterday. Winter gets a B+ from me. And it hasn't been that cold which is good for me as I'm not a fan.

Have you guys figured out where the low is at? If I'm seeing it correctly, looks like it's still heading east.

Looks about right.  

[SilverFallsAndrew]

The radar looks like a dragon attacking Portland.

This where ECMWF says it is right now... you nailed it.

How much snow did you end up with last week?

Similar here, the gap between west and central/east metro evened out a bit during the midnight hours. NE did the best though

[TT-SEA]

00Z ECMWF... the snow in Seattle comes primarily in a c-zone tomorrow afternoon.

Looks great for most of the Willamette Valley

Precip just started here in Rock creek. Oregon. Looks like cold rain…

That weird wedge to the NE doesn’t look right? 

[TT-SEA]

ECMWF shows an interesting feature tomorrow afternoon and I think its actually a deformation band on the southern side of the low because there is no strong onshore flow to create a c-zone.     Its shows it being warmer in my area than in Seattle tomorrow afternoon.  

[Olive1010]

Or actually looks like a mix

[Olive1010]

Doinko whats happening there?

I’m hoping it’s cold enough though because it shows the peak of it right around 4pm and that’s how I would get most of my snow on that run.

[TT-SEA]

This is snow per ECMWF from now until 4 a.m.    It appears that the activity approaching the Seattle area on radar might bring some accumulating snow overnight.  

[Olive1010]

Looks like theres some more snowflakes mixing in

Looks like a mix, mostly rain. Precip is still light though

Interesting that EURO wants to give PDX-Eugene accumulating snow early or midday tomorrow-- if it came to fruition it certainly would be an eventful commute up in the hills.

[TT-SEA]

Here is the 1-hour precip loop from the ECMWF... gives an idea how what we see on radar will evolve over the next 18 hours.

What does it look like for the precip total? Looks like a strong Olympic rain shadow.

That does seem like a light deformation band though. I would hope the precip rates would be heavy enough to have snow in the afternoon.

It looks to be the main activity for the south sound. 1k wrf looks great for Everett

Yeah... gradients are totally flat tomorrow afternoon.    It can't be a convergence zone without strong onshore flow.

Precip seems to be a little more but marginal temps are killing it for seattle south

[TonyP]

Cold rain in Tacoma at the moment 

[Olive1010]

Looks like right now some more snowflakes.

[MR.SNOWMIZER]

Light rain and 33 here.

[TT-SEA]

Here is the wind map loop through tomorrow... you can sort of track the progress of the low inland and then it appears to just fall apart.  

[Perturbed Member]

00z Euro brings this little surface low ashore at Newport around 7 AM. Good band of snow for south PDX metro and SLE.

39 at Seatac right now might be too warm for the Central sound too

[MR.SNOWMIZER]

Snow level is around 1000ft right now in this area.

Weird, it's not that strong a shadow, maybe just enough to keep the precip too weak for accumulation out here. The orientation doesn't look right based on the current radar returns though. The heaviest part of the band is oriented more N-S rather than NE-SW. The NW tip of the Olympic Peninsula has been relatively dry so far.

[lowlandsnow]

Looks like this event might be over in western wa except for those north of Everett/above 500 ft

Wow that doesn’t make me feel good about this.

[Weiner Warrior]

Precip about to hit here. 36 degrees with DP at 29. Hopeful for snow
