December Weather In the PNW

[GHweatherChris]

Little sleet here in Westport mixed with rain.

[Guest Dome Buster]

Yeah that does look good.

 

How fun would it to be up at hurricane ridge right now? That's some deep moisture headed that way.

[Perturbed Member]

HRRR like the last RGEM is positioning that southern low quite well for PDX, taking it further south. 

 

[Timmy]

Remember last night when everyone was taking shots at pdx nws?

[Bryant]

Rough week. Near 1” of qpf a couple days ago, all rain 33-32 degrees. Today a few hours of sleet at 24f.

Should probably go make your wife happy now that all your excitement is over with

Yes. I'm noticing a more W/NW movement of the front as opposed to N/NW. Perhaps that development is what slows the progress tonight and keeps offshore going? Pretty dynamic situation, almost looks like a deformation band signature, albeit a weak one.

will do! Don’t tell my girlfriend!

[seattleweatherguy]

Yeah that does look good.

Any of this going to hit King county

[BLI snowman]

Heavy snow here, up to 1/3" already.

Yep, I think the NWS handled this about as well as they could have so far. Especially when considering how crazy the models have been. 

[Jesse]

We’ve only seen zr and sleet here so far. Now nothing is falling.

Yes, but this isn't over. Still expecting snow later today/tonight. Warm nose not making it this way and I think we will get heavy enough precip to do it. Currently sitting at 29 deg/24 DP.

Yeah I'm wondering when the next band will arrive.

Pretty much a non event there considering it’s 5000ft. Similar to many other days with snow at that elevation

Well I know that silly. Just saying how fun it would be.

Yeah, things will get very interesting if that secondary low goes that far south. Should really slow down or stop the warm air advection aloft and keep the easterlies cranking. Couple inches of snow as the best case scenario isn't totally crazy talk. 

[Guest Dome Buster]

Noticed my local observation site has shown the dewpoint dropping from 26.7 earlier to 24.4 now. Interesting to say the least. Especially considering what has gone through already. This is some strong outflow.

[TT-SEA]

Dewpoint in Olympia is 28... but 9 at SEA.   

[Guest El nina]

Yeah I'm wondering when the next band will arrive.

Looks like it's already showing up on radar.

Yep, looks like around 4-5 or so? Towards the end of the Seahawks game.

I'm thinking more like 3-3:30 based on how fast it's moving.

Right about peak heating so that's unfortunate.

[Timmy]

Latest nam hi res is really bullish for moisture. Especially for nw Oregon and sw Washington.

You were gonna have a green Christmas anyways right?

[Jbolin]

This is just south of Chehalis

 

EDIT: It should start snowing in OLY in about 30-45 mins

[MossMan]

Temp 31, DP 28. Clouds really lowering now.

[TigerWoodsLibido]

Most likely

18Z NAM says we get nothing until the backwash starts after 10 PM.  31 here as well.

[Timmy]

Cam Newton!

[Winterdog]

Fig Newton!

[MossMan]

18Z NAM says we get nothing until the backwash starts after 10 PM. 31 here as well.

I just find that so hard to believe looking at the radar.

[Guest Dome Buster]

I think that band comes in after dark. Offshore flow is strong. Probably take a while to start precipitating again.

What time did the Euro get things cranking for our area?

On second thought that is moving in quick. Let's cross our fingers.

[Winterdog]

Kinda hard to tell but at 4 PM it's in Seattle so maybe by 6 PM I would guess.

Yeah, looks like we could be back to snow here soon. Still have flurries here. Good sign that I am able to maintain snow even under very light precip...

[Guest Dome Buster]

My temp has been steadily dropping today despite the cloud cover and moistening atmosphere..very good sign.

 

Currently 27.6 degrees/25.4 dewpoint. Not too shabby.

[Geos]

Moisture seems to be moving in fast. Already showing on Seattle radar.

 

[MR.SNOWMIZER]

The first snow flurry has hatched above my house.
