Light snow currently. Right on the edge of precip

The GFS is a thing of beauty.  As an added bonus there is some clearing early Monday night that allows things to freeze up before the snow hits.  Mid levels are certainly cold enough.

I thought the rgem and icon both looked better than the gfs. Gfs looks dry.

We… we have a WWA for up to 3 inches midnight-10am tomorrow.

Wouldn’t be surprised if we get added to that in pierce county based on how the radar’s looking.

I look at any snow tonight as a total bonus.  Some places will probably have some though.

It should include the entire area. Makes no sense, it will be cold enough and if anything your area will have more precip than mine because of rain shadow.

If the trajectory remains more WSW like this I'm sure they'll expend it northward.  Going to be a fun few days coming up.

As long as I'm south of the shadow, which looks possible.

[MillCreekMike]

That is such a dumb CZ

You guys deserve it, before the snow last week Olympia was completely skunked every event this winter.

NWS says you won’t be shadowed and there’s even a WWA for your area.

Lower Columbia, too. Wasn't expecting this tonight.

Thanks! We've had a nice few days here...finishing strong.  

[T-Town]

These showers are pretty fun. That one that came through was pretty close to a direct hit here. Doesn’t happen too often. 

[flya00]

Hail coming down quick now in Chilliwack

[MillCreekMike]

Looks like it’s dropping a bit south but it’s losing steam on the west side

[joelgombiner]

Sun here, but dark, towering clouds to the north and south. 

[SnowySeeker50]

Sitting on the edge of the corridor of nothingness isn't fun.

[Kolk1604]

Currently 42 after a high of 48 

[MillCreekMike]

Not at home right now but a pretty heavy band about to go right over my place. Looks like hail/graupel right now.

[PuyallupChris]

I feel your pain. I’m right on the north edge of the south blob now and I can see precip out towards Tacoma from one window, and up the valley North from another, while bone dry here. Been a rough few days.

That seems really suspect, but you never know I guess.  This isn't really a Hood Canal situation.

[snow_wizard]

Already back into the 30s here after brief flurry.

[MR.SNOWMIZER]

Made it to top of gold mountain.  8 inches up there fresh. Man it was windy and cold up there.  28 degrees there. The nws used to have a observation up there and it went off line few years ago. That observation up there was a valuable tool.  When it was working I knew without a doubt if the airmass would support snow just by knowing the temp there at 1700ft.

[NWbyNW]

It has been hail-snowing since 2:40pm non-stop here.  Yet it is 36F degrees...

At least you have had a significant snowfall this season so it hasn’t been a total bust for you.

[SnowySeeker50]

Back up to 42 and sunny. Drop and rise about 5 degrees every time another blob passes overhead.

Not sure if this got posted.

They are sure diligent about dropping an advisory for every last little chance now.

[Cold Snap]

Currently 41.3. Only have a little bit of snow left on the shaded areas of the dirt now.

Monday night will deliver for everyone it looks like. We always do well here with a low moving in to the south.

Yeah it was predictable. They got caught asleep at the wheel for the big one and now issue warnings and advisories for even a trace. Rest of these "events" are almost certainly 0 snow in the city itself and an inch or two of wet snow in outlying areas or hills. Conversational snow.

Hopefully the NWS actually pays attention next time and also focuses on meteorology instead of pure statistical analysis of their 2 favorite ensemble models the SREF and NBM.

Elevation really is important today for air temperature.  Bremerton airport is 39 and 440ft. Another observation near me is 38 and 500ft. I'm 34 degrees and 650ft.  Those places mentioned are just a few miles away from me.

[Cold Snap]

18z Euro looks great!

The setup actually looks decent for Portland tonight. That low is to our west to allow some weak offshore flow to build this evening and it lifts a possible band of snow through the metro area late tonight. Lowest elevations could pick up some sticking snow. The rest of the week looks meh for the actual city. 

[MillCreekMike]

Welp I definitely got the strong CZ I’ve been wanting… Too bad it’s not cold enough

[Meatyorologist]

Mesoscale models are growing happy about bringing in another round of snow this evening to the Sound. Offshore radar is juicy and the profile is convective... Could get real interesting. These are the kinds of snow events that when they work out, they can dump quite a bit of unexpected snow.

[Phishy Wx]

 

[MWG]

They added another WSA on top of the WSW for 1500'. I hope we get something for us 1400' plebs!

It shows like 8 inches for you and only 2 inches for me!   

I was really expecting to get decently buried up here this week.   But the next system on Thursday and Friday appears to be too warm even for my area... so it all comes down to Tuesday.

Seems like focus will be right over the Seattle area too.

[WildrootParable]

After all day of full sun and bluebird skies, in the last 10-15 minutes we've completely clouded over and we're in a snowglobe! We had a lot of melting but there's still a few inches on the grass and gravel, so I'm curious to see how things go tonight when the temperature drops.
