For the life of me I can't understand why people have had so much doubt about this thing.  It's been advertised as clear as day for a few days now.  It's been obvious the -NAO would make it work out just fine.

It hasn’t happened yet. We’re still ten days away from anything even getting close to starting to happen. You are surprised people are skeptical about long range models and reluctant to go all in right now after how many times we have been burned (you included) over the years?

But if there is already cold air in place, wouldnt some onshore flow be good for you guys instead of just dry northerly flow?

If thicknesses drop below 522 then it should be snow even in onshore flow.

8 ensemble members drop to -10 or lower for Seattle on this run.  What an improvement!

Cmon Jesse this is one of the predictable essential elements of the potential interesting future weather.

GEFS is more open to Arctic air than any of the previous runs. Let's keep that going.

Shadowing is the problem for the Willamette Valley in cold onshore events.

Besides the models everything says we should get hit.  Context is important.  People are way too negative on here IMO, but that's the way it is.  This thing has about the most support I've seen.  La Nina winters that totally flop in the front half usually deliver well in the second half, especially when other areas are scoring big stuff early on.

People on here have unrealistically high expectations for our climate. Some cold onshore flow with an inch or two of slush on the bark dust isn't really going to move the needle if we are talking about la la land.

So what kind of a pattern does work for snow there?

Mountain wave where the cold air blows over the cascades and down the McKenzie then a low comes in around Cape Blanco or a bit south.

Anafronts, suppressed jet, overrunning events. 

Cold onshore flow can workout for the valley, but shadowing does tend to occur quite frequently. 

If showers are moving from the NW I even tend to get shadowed pretty badly.

I understand and acknowledge that we have a lot of boxes checked in our favor right now. And there are indeed some who are unnecessarily negative here and others who are unnecessarily positive, but I think overall it’s pretty balanced. But you know as well as anyone that nothing is ever a slam dunk until the good stuff is at our doorsteps. Simply stating that fact and nodding to the inherent uncertainty that gives this stuff half of it’s fun should not be construed as being “way too negative”.

Southward moving/stalled arctic fronts with an attendant area low pressure near the coast can too. In Dec 2008 that happened produced multiple rounds of snow showers at my house for several nights 3-5". Fun stuff.

Yep, the Euro is much more bullish on blocking. And from what I've heard, the Euro is much more accurate with its MJO predictions, which, lo and behold, is the key factor into forming high latitude GOA blocks. The SSW may have already happened, but the details surrounding its developing impacts are coming into view, very fluidly (no pun intended).

Likewise, the CMC is a great solution, much like today's 12z Euro. Stationary block with a warning shot beforehand. Though I don't see any impulses, I'd be willing to bet things get much colder 3-5 days after this point.
