December 2016 Observations and Model Discussion for the Pacific Northwest

[TT-SEA]

The other amazing aspect of this situation is how fast it changes to my west.

 

Tiger Summit which is at 1,300 feet does not have much snow at all... but the cold air scours out faster there.    There are places in North Bend at 400 feet that are buried in snow... and they are 900 feet lower than Tiger Summit. 

 

The Snoqualmie Valley just traps the cold air perfectly in this situation... but we still get tons of moisture overriding the cold air.

Whiskey on the rocks, 00z ECMWF and the 00z GFS while the girlfriend watches reruns of Friends is my new Friday night.  When did I become this???

 

Haha, I can relate to this feeling. 

[ShawniganLake]

Looked outside a few minutes ago and was surprised to see a star filled sky with the moon reflecting off of the fresh snow. Did not expect it to clear out tonight. 31F with a light north breeze.

High of 65 at PDX today. FroYoBro was just one day off!

It amazes me what your location is capable of at only 1100 feet.  There is a town east of me (Oakridge) that is at 1200' and probably only averages around 12 inches a year.

 

Have you kept track of interesting records?  I'd love to know what your top snow depth was, top seasonal snowfall, etc was.  I'd also love to see a pic of your Dec 2008 driveway.

How much snowfall has YVR seen this week?

Looks like 4.1"

[Weather101]

How much snowfall has YVR seen this week?

Um 4" I believe

[MossMan]

Must have had some freezing rain...just let my dogs out and noticed my truck was incased I'm ice but temp now at 33.2. The 6z must have been bad or everyone is passed out from Whiskey and Friends marathons!

[westcoastexpat]

Richmond, we did really well today. I always seem to have different amounts then YVR, a real micro climate one you get away from the airport.

 

I somehow ended up with 4", pretty happy since that's what I told all my friends and family the day before... and then I was bombarded with "WHERE'S THE SNOW?" A little late to the party, but it verified...

 

Have a feeling I'm going to bite it today/tonight though, where I had forecast another 4"... praying for some surprises.

[westcoastexpat]

How much snowfall has YVR seen this week?

 

YVR itself tends to do very poorly with snow compared to most regions in the metro area. I'd say in general, most places have seen 6-8" this week, with some lucky spots reaching a 12" weekly total. I know the Coquitlam area has done really well with both events. Note that a lot of what fell across the region on Monday was almost gone by the time Fridays stuff rolled around, so the snowpack isn't all that impressive. But Monday and Friday ended up having pretty much identical totals for most people.

[TT-SEA]

28.4 degrees here this morning and NOT snowing.

 

Looks like another 3 inches or so after I went to bed at midnight.

MM5 NAM takes the low farther north over central Vancouver Island today... and is warmer than the 00Z WRF for our southern VI and Whatcom County friends,

[MossMan]

Up to 34...warmest it's been in several days.

[ShawniganLake]

MM5 NAM takes the low farther north over central Vancouver Island today... and is warmer than the 00Z WRF for our southern VI and Whatcom County friends,

Forecast calling for 8-12" more snow in the Fraser valley. My location is right on the edge for the warning for 2-4". Currently 29F and cloudy with the radar filling in to my west. Will it be freezing or snow or a quick warmup to rain

 

The power is out here for the third time since last evening. The heavy snow load must be picking off some weak trees.

Last nights Euro will be just a tad off then I take it for today...oh well we still have next week...maybe.

PDX tied an all time record yesterday with a 1 degree rise in temperature. High was 33, low was 32.

 

Previous time the record was set was January 16, 1960, with 34/33. That was a couple days before a huge snowstorm....

The WRF was probably the worst model for yesterday's event, had everything very warm--but both Vancouver and Bellingham never even went above freezing. I wouldn't put much stock in it.

[Heavy Snow]

My 0.5" of snow melted. I don't want to go into this Arctic Blast with no snow! Please 12z models bring back the moisture!

I was trying to find pictures from 2008... must be on a storage drive somewhere around here.   

[crf450ish]

Really this is the most prolific snow producing scenario here... cold air supply to the east with copious moisture streaming in from the southwest which would just result in another very rainy day otherwise.   

 

C-zones are second behind this set-up.    

I would venture to say your snowpack isn't going anywhere anytime soon. 

[crf450ish]

Looking like a freekin high desert forecast in winter for me next week.....jeez

This was the December CFS forecast. Oops!

It's only the 10th.

I can't tell if you're being sarcastic or if you think that actually has a chance at verifying.

It was a joke.

Daylight pictures...

 

 

 

[SilverFallsAndrew]

The 06z GFS not nearly as good. 

[Phil]

It was a joke.

I expect better from you.

[Deweydog]

I expect better from the CFS.

Amazing what a little tequila on an empty stomach can do. My posts last night were lol.

[Deweydog]

Definitely a bit of a moderating trend for the mid week stuff.

I thought you were a recovering addict? I'm calling your sponsor...

Only way to drink that stuff or it will empty your stomach for you. Lol

[Phil]

More like recovered former-addict. Everything in (relative) moderation for me now.

[Phil]

Lol, that's what everyone says but I never had that issue. In fact, I don't think I've hurled or even gotten sick (generally speaking) in over 15 years. Not sure how much longer I can keep that up.

[Heavy Snow]

Possible snowstorm Thursday on the 12z GFS but just misses most of us. Systems are going to far South! I need Snow going into this Arctic Blast!

[SilverFallsAndrew]

The Sun-Tues period is looking a lot milder down here than it was a day or two ago.
