That's crazytalk but I gotta point something out here.... Whatever relax the ens have been showing d10-15 is starting to look like a push back in time (shocker). I'm sure it's coming at some point but right now ALL ops show a NASTY AK/EPO ridge coming back. Almost goundhog day style. I noticed it a few days ago but now it's coming on strong. Check this out:

Euro:

And GOOD GOD the CMC lol

We've talked about this so it's not a revelation of any kind. It does fit into a lot our our collective thinking over the last 6 weeks. The AK/EPO ridge is the only thing that seems we can rely on in the long range. If the ops are right and the ens follow (they kinda are now but have a trough in the west is winning) then whatever "relax" after the 6th or so will be VERY short lived. Fun times in lala land. 

Think about it as an inverse. If we were torching now because of a craptastic North Pacific and looking at a long range prog that was ambiguous and kinda cold but showed that same craptastic Pacific pattern reloading we wouldn't feel very good. So by inverse until I see firm signs the epo dominated pattern is ending I'm not going to worry about uber long range torches.

Being a snow lover in this area patience is needed in EVERY pattern.  We have upside potential that many places lack. It's not the worst. But if you are a fan of consistent snow this is not the place to be.  And thank you for the kind words. 

What I  Iove about this area is the potential for a big one. We have more potential than other places in the US that are much colder. It doesnt happen often but when it happens it really happens...lol. usually we wait 6 to 8 years between each one. Except the magical 2009 / 2010 season.

Bob, PSU, etc all, looking at the maps above, verbatim would that trough be too far to the east for us? I know it's fantasy range and all that...

It's just a snapshot in time. The 48 hours before those panels is where any threat would hypothetically be. And down the line would continue with shots of cold and as long as we keep getting cold refreshes we remain in a potential pattern instead of a shutout. I just wanted to point out the AK/EPO ridge @ d10. Ensembles hinted at a warm NA pattern d10-15. That won't happen as long as the east pac cooperates. We could easily warm up with a trough west/ridge east but it would be very temporary instead of a "new regime".

The storm day 8 on last nights run looked so much like the dec 2000 storm. Kinda depressing to look at even knowing it's not going to happen like that.  For some reason I don't mind seeing things south or cutting as much. I can remember plenty of times those trend better. But when things start blowing up late and clipping New England in a Nina I can't remember any instance that it ended well. It's the worst look imo.

Thanks. It's probably a lot to ask for, but sneaking in a moderate event between the incoming cold this evening and the one depicted above would be stellar. A couple of inches of snow with cold this deep would stick around and go a long way to improve the mood around here. And who knows? Maybe Saturday will deliver a minor event too.

That look on the Euro is just bad looking though. Ggem is carved out much better. 

I agree there. Just pointing out that they both have the same little piece out west and a general trough in the east. Whenever you see 2 ops looking the same @ 120 hours it's worth noting regardless of how it plays out.

I definitely agree. Plus there is plenty of time to get it right. Should of kept my mouth shut ;)

This entire period has been derailed by a combination of wave separation problems, and the amplitude of the west coast ridge. 

Yea, the "out of sync for snow" has been very prevalent. We continue to see fairly wide swings as you get out to hr96 and then it magnifies from there. It's not a great setup. Not dancing around that but there is a way for it to work embedded in there and with the way things have been going, writing anything off (good or bad) beyond 3 days is proving to be the wrong way to go.

This is a bit convoluted but it's easy to see the way it could work. I'm not mad at this panel. Seeing "uphill" isobars @ h5 is never bad in the pattern were in. haha

Yeah it was a lot further west.  Gave a lot more opportunity for ridging to build ahead of the system.  Otherwise, that -anomaly along the SE coast is going to kill us.

As long as we have cold (which seems to be in abundance this year) we have a shot at some snow. But my expectations of anything more than nickel and dime events have been drastically lowered due to the issues I mentioned before.

For better or worse (pick your poison), the lead time is in our favor for something to work out. It's complicated and that's always the first sign of trouble but we have something to watch other than our breath in cold air under sunny skies.

i think Jan 4 is really our only legit chance in the current pattern. it needs some help

The entire thing is just kinda popping up right now on the ops the last few runs. I don't think any op or ensemble is going to tell us much right now other than it remains hostile for a good event.....but not impossible

we do well with impossible so im hopeful:). I just wish it wasnt the GGEM(who gives me average of 200 inches of snow a year) leading the way

It's sorta bizarre how h5 evolves. It's like a tango between shortwaves. Ridge out west on the euro needs to move about 100 miles further west....and the 2 pieces need to play nice together...and....well....everything else.
