I'm surprised all the Oregon and SW Washington people aren't on right now talking about the GFS.

Phil soured everyone’s mood last night with his 1999 talk.

What can I say..I haven’t liked any of the pattern developments over the last 7-10 days. And I’m looking hard, from the tropics to the pole(s).

Hope I’m wrong but I think the chances of a 1974/75, 2007/08, 1999/00 type winter are increasing exponentially.

I agree. We are supposed to be +15F for the next 10 days. They can't even make snow up here for the next week or 2. Even if we get cold air after that it will tough to open any terrain by Christmas. Even the worst drought years we had some runs open by Christmas

Looking at current weather... the IR satellite shows yet another AR event taking aim at SW BC and western WA.   It feels like this has been a semi-permanent feature for the last couple months.    I am looking forward to anything different.

It's getting ridiculous.  15 inches of rain here this month.

The 12z Gfs is really just model noise at this point. It’s possible we see something decent the first half of December, but more likely we won’t. 90% of operational runs and ensembles show nothing.

Impressive amount of cold air getting involved with this run. I like the angle of attack,  should pick up lots of moisture. 

That is one bloody impressive run.

ECMWF shows the rain just never takes a break over at least the next 5 days... western WA is always in the direct line of fire.  It just goes on and on.

Last nights ECMWF was cold in the almost believable range.

I haven’t closed the door on something decent, but some consistency would be nice. We ll see where this run goes.

It remains significantly wetter than the GFS for the Puget Sound. It will be pretty stunning if I end up picking another 4" before the end of the month like it suggests.

Still seems kind of subdued on here today.  It's obvious the pieces are going to be there for cold weather coming up.  There's a good chance it's going to work out.

12Z ECMWF shows SEA getting another 4 inches of rain before the month ends.     Going to be right up there with November 2006.   The difference is that the end of that November was cold and snowy so we got a break... no such luck this month.

What's everyone waiting for? Seattle and Portland are world famous for rain. It's Minneapolis that's famous for snowstorms and cold

 

So?  We do get some good stuff here sometimes.  You seem to be really stirring the pot this year.

Maybe... but sometimes when we play with fire in terms of cold air we end up getting into an even wetter pattern.    I am trying not to think about that but its hard.

Historically speaking these excessively wet periods don't drag on for months.  Something has to give.

I am craving cold 850mb temps.   At the very least that shuts off the firehose.

I can't figure it out.  Yesterday we had a bad run and everyone was bummed, and today we have a great run and everyone yawns.  I guess I'm the only one that thinks we're in good shape.  Makes it kind of a bummer to come on here.

It’s about consistency Jim. It’s all just noise at this point. Don’t force us to celebrate with you. I don’t even think it’s negative on here.

850s are -8 on the ECMWF by Friday night.  Cold enough for snow and well below normal temps.

There has been too much model volatility for anyone to believe anything.    But obviously if things come into focus soon then everyone will be on board.
