December 2016 Observations and Model Discussion for the Pacific Northwest

[Heavy Snow]

You might have to add the Dec 2016 map to your signature along with Jan 1950 and Jan 1969!

 

Maybe.

[Front Ranger]

Tacoma McChord hit 17 this morning, not bad.

[MossMan]

Tacoma McChord hit 17 this morning, not bad.

I'm a little dissapointed with my 18F this morning since it was 19 when I went to bed last night. Was hoping for 16!

[Front Ranger]

This might be one of those very rare situations where Tim gets relatively screwed.

[FroYoBro]

30 degrees and raining, but the roads actually look pretty slushy now.

Warm asphalt!!!!

[Sometimesdylan]

Clouds cleared out today. Cooling down. 

 

Sitting at 14 degrees. North wind is starting to pick up in some places, but calm where I am. Trees still holding snow. Pretty evening with the alpenglow reflecting on the trees.... just about dark now tho.

[TT-SEA]

Not likely.   

 

Maybe initially... but the models show my area getting hit good through tomorrow for sure.   I think it will stay cold enough for snow here through Saturday morning and there is lots of precip through that period.  

 

I am guessing I will beat the totals for all of the area except maybe the North Interior and Vancouver Island and the lower mainland.

[Geos]

Temperature inching down here. 33.4° now. Dewpoint went down to 18°.

[bainbridgekid]

Definitely some "buzz sawing" happening along the North edge of the precip shield as it approaches the Sound.

 

Not surprising given the dry air and East winds. It will probably still be a couple hours till things really get going around Seattle.

Probably gonna lose out to Hood canal. Definitely gonna beat me I don't see a way I'll get more than 3" out of this based on the models. This valley is surprisingly really dry and affected by downsloping in winter.

I only meant tonight.

Vancouver, BC temp dropped as some outflow gusts pushing in as the low approaches. Good sign. With dew points so low, the dry air will take some time to moisten but should give some great ratio snow once the column moistens up.

[bainbridgekid]

To give an idea of the kind of temperature drops we may be able to expect from evaporative cooling, OLM went from 37/17 before the snow started to 31/31 two hours later. McChord went from 36/17 to 33/30 in the last hour, so not huge temp drops, though definitely enough to give us snow.

 

It will be interesting to see what SEA (36/12 currently) does over the next few hours.

Almost every single place south of Seattle has done very well with switching over to snow at precip onset. KBFI sitting at 37/14, KSEA at 36/12. Should be snow right off the bat.

 

I figure Seattle area will end up hovering around 30.

[HighlandExperience]

We need a report from the swamp

Well... I already have 4 inches of snow on the ground and its been a winter postcard here since Sunday so I can share tonight.  

[luvssnow_spokane]

The buzz saw is legit here in swamp land. Not a single snowflake and dry as a bone.

[westcoastexpat]

That's not very nice...

[Goducks09]

Okay, so, when is it appropriate to start focusing on and wishcasting for the next event...assuming there is one coming?  Haha.  

 

My ADHD is kicking in and I'm over the 3/4 inch snow we got in Downtown PDX.  Was really hoping for the 3-5 inches.  #feelingrobbed

[Weather101]

32F here

[The Swamp]

We need a report from the swamp

Bone dry in the swamp. Not a flake to be found. Well, there is me.

Always have January

[SilverFallsAndrew]

Feeling pretty good about how my forecast turned out.

 

Looking forward to the 00z runs!

[seattleweatherguy]

So what time will I see snow?

[The Swamp]

So what time will I see snow?

You may get nothing. It happens sometimes. I can attest to that.

[Weather101]

It looks like all the snow is actually going to miss Bothell

Me too, this wasn't quite enough to get my snow fix. I need mooar.

[MR.SNOWMIZER]

Yes... Yes of course.

[seattleweatherguy]

Wow what happened?

[TT-SEA]

10:57:35

 

Give or take 20 seconds.

[seattleweatherguy]

Praying for the best

[westcoastexpat]

Wow what happened?

 

I'm really speechless... I wasn't expecting this... there seems to be this very dry pocket right over Bothell and the snow keeps evaporating and seems to be sliding by to east...

Maybe my luck or bad radar detector

[seattleweatherguy]

I see the pocket, but there's snow behind it for now around 8..

[westcoastexpat]

Maybe my luck or bad radar detector

 

Is it snowing at your place? If it's not, then I guess the radar is working fine 

[HighlandExperience]

Good news NWS reporting light snow in Puyallup.

 

#hope

No snow praying for the best

[snow_wizard]

It will be fine later.  It's taking the moisture a while to overcome the dry air.

 

Interestingly the Euro shows it freezing or below tomorrow morning, but no new snow after 12z in spite of plenty of moisture.  Could end up freezing rain I suppose.  On the other hand snow through early tomorrow morning wouldn't shock me either.  The numbers aren't terrible if east winds continue.
