Energy “crashing into the west coast” can go both ways. It can keep a system from cutting too and they can also temporarily amp up the ridge downstream of it…it all depends how the trough hitting the west coast is behaving. If it is n the process of digging, then it will help amp the ridge ahead of it, if it’s in the process of weakening, then it will act more like a kicker. 
 

A lot of big dogs had energy hitting the west coast…Jan 2016, Feb 2013, Boxing Day 2010, Feb 2001, Dec 1992….those are just the ones I know. But there are likely others too. 
 

We don’t know if it will help or hurt yet. It’s one of those nuances that isn’t really known at this type of lead time. 

there are Kocin/Ucellini case studies of straight shot waves that rolled up upon hitting the EC longitude, with limited aft ridging to complete the total more typified planetary wave structure. 

I think folks get to hung up on idealized form ...and tend to start hand waving too soon when those features don't fit that preconception ... a lot faster than the should be,.

- GFS is getting happy with the N-stream ...bullying the hemisphere E of 110 W and above 40N out there.  This is actually fairly typical for this guidance.  Not sure how that corrects when/if it backs off on that

- MJO may be less forcing given to the momentum distribution ... as modeled.  However, the current behavior of the Pacific polar jet, across the Basin is rather atypical for La Nina, indicating some decoupling is likely taken(ing) place.  This latter facet does lend to MJO punching through the La Nina 'firewall'.  Last year something similar happened with a strong wave presentation around Phase 8 and 70..80% of the ballast was 10 S of the equator. That matters.   That said, the Basin's NINO look may be receptive/entice the wave to span. What's the SOI outlook?

- 12th thru the 15th are still eligible, just by numbers of respective ensemble membership. The operational version of both clusters appear to be flat outliers.  No help from the teleconnectors ...as there are two events possible ( really) through the 16th, and they are sub-index mass conservation so it's going to come down to ensemble trends more so than waiting on emergence for these.

And this is a great post, along with Wills earlier post explaining something similar.  
 

Ya got the trolls that call a system a dud from 10 days out, and then some that call for a blizzard for any potential amped system that can become a coastal. Both ends of that spectrum are absolute lunacy.

C’mon…everybody knows clippers don’t exist anymore, and developing clippers…what are those? Lol. 

It has been quite some time since we've seen one of those clippers dive out of Manitoba and redevelop off the coast of Virginia and roar up the coast at a snails pace.

We're overdue. We are overdue. Just not sure that this weather pattern la Nina is conducive for Clippers. Might have to wait till next year for a really good chance at a clipper system ( but there's always a chance ).
