It will be on our side....at least a piece of it by the 3rd week of January if not before then. Trust the weeklies. This reload of the pattern thru that time has been consistently modeled. Until it fails completely as lead times shrink I have no reason to doubt where we are headed. Becoming more optimistic daily. And like both u and psu noted, we can still cash in during this time of climo without the PV parked to our North as long as we have the PAC help. We are entering that time of climo where we dont necessarily require absolute perfection. 

I tend to agree with you. GEFS hasn't been handling the pv too well lately on its runs so i am not overly concerned at this time. Just more so pointing out the fact that the GEFS has been trending this way lately. But again, we can deal with it being on the other side as long as we continue to see the PNA/EPO ridge to shut off the PAC air and pump the colder arctic air down underneath the blocking.

It's about to get real....Models continue to correct to a more amplified MJO heading toward the promise land.

That's good to see.  It makes sense that the tellies are catching on to the new regime, and think that by this time next week, there might be a lot of weather porn being shared on the board.  Just hoping the STJ stays active and close by once we get into the New Year.  That's been in the back of my mind for the last few days.

In my mind as well....I am banking on a good NA to give us shots regardless.  Even with periods of suppression a good block in GL can give us shots when things relax....if that block is pretty well sustained we should have several bouts of suppressed/relax. Hoping at least...

That one of those things that can be a bit of a wildcard, or? (now does the Niño usually drive that?)

yes and no.  Base state we are in usually includes an active STJ, but as I know your learning, there's other influences, and too much blocking in the NA can lead to suppression in the east.  West based nao gives room for STJ to stay close enough for storm track to be favorable.  With split flow out west PJ and STJ split in west and converging in midwest can lead to overrunning events (my favorites), as they are a steady stream of moisture coming out of the SW and being ejected east to meet up w/ the PJ and steady long duration (typically light/mod) snow events can occur.  That's another way we can win.  

Hope that makes sense.

Since @frd is really slacking..

Boooo...... I have to get more coffee. Will be posting soon. 

I do like the -NAO look later next week. May end up being even more so negative. The goofy GFS I think is struggling with this, I would speculate a further South track over time.

Could you (or someone else) help explain how to read that?  If I’m reading it correctly, we’re currently in Phase 5 (red line correlates to the date) and the yellow lines are the ensemble members view of where we’re heading?  Grey is the spread?

12z CMC has the NYE storm... but its rain down here.  Track is a bit NW of where we would like it... but its there.  And there is a HP in concert moving across Quebec... so maybe it would be frozen. 

CMC is really close. But both it and 12z gfs do a perfect job of having all the precip avoid what cold air we get. Gfs then brings the Arctic hammer after New Years.

2” increase from where it was before? That’s a pretty big signal at 10 day leads.

yeah, it goes from a dusting to 2" or so in D.C. 6 members seem to jump on it, which isn't anything to scoff at. A couple of them are definitely the snow output on WxBell being funky though, counting sleet/frza.
