Bob, I realize this is only fantasy land, but I wanted to ask a few technical questions regarding this map.  

 

1.  Would that classify as an east-based NAO?

2.  Would that west-coast ridge axis be a little too far west than ideal?

3.  If #1 and #2 above are "yes", then would this leave open the possibility for OV cutters?

 

Appreciate you taking time to answer questions for someone trying to learn.

It's pretty much a solid -nao. AN heights from Baffin Island to Iceland. It's very similar to what HM has been talking about. The PV is on the move south and heights are building above it. The look is also a solid -AO. The numerical indices for the run completely tank (-4 AO / -2 NAO). If you run the loop you can see heights are building so it would imply high latitude continuing to build down the line.

 

East based will typically still have BN heights over Baffin Island/Davis but ridging poking into greenland from the Atlantic. East based are transient more often than not. West based usually much more stable. The look above would also imply some stability. 

 

As far as the ridge in the west goes, it's fine. Nothing would cut. The hl blocking and displaced PV would probably favor a suppressed track if anything. 

 

Of course this is just 1 op run and absolutely nothing to get hopes up for now but I found it quite coincidental after the disco with HM yesterday.

Thank you for the explanation!

Still looks solid, but yes this has some upside potential to it in addition to what is shown. 

 

Yes, still a great vort pass either way. It's not zipping along either. I like the idea of a long duration event event if it's not 1" qpf. Wouldn't take much for this to be a substantial event for someone on the coast.

GFS is more north for Monday. Closes h5 right over head and rolls it across. 50-100 miles south and we would go boom. 

 

You're right - I spoke a panel too soon.

 

Do you think a weaker Fri/Sat system results in a further north track - and that correspondingly a deeper low early in the weekend drives the Monday clipper further south?

What I like about it the most I think is to get a solid 2-4/3-5 event, this doesn't have to go out of its way and overperform. Its a powerful system and a good vort rolling through. There is the chance to do what the euro did last night, but as long as it doesn't start zipping north on future runs, its not an overly hard set-up to model. Of course these sytems jump around but now were at a d4.5 lead which isn't THAT far out.

We need that for the boundary layer too.  Verbatim the GFS is rain despite the 850s. 

 

Yep, slp tracking overhead is never a good thing for surface temps. I'm sure we'll see plenty of wobbles on the track over the next several days. So much happens in front of it I'm not even really thinking about it that much and it's less than a week away. lol. Busy times.

I don't think we've seen something like this since 2010. The ss shortwave is digging a bit too much but @ d10 fantasy who cares. All I see here is a phased miller A down the line. -AO/NAO/+PNA and streams about to phase. Arctic air in place. I'm surprised Hberg hasn't been by yet. This is a good a look as we've seen in like forever. It will disappear in 12 hours I'm sure but definitely fun to look at. 

 

I'm sure folks in the SE are pretty interested too.

Very interesting look for sure. I hope this sticks around longer than the last promising pattern we saw...

that confluence.  (as you said) much like we saw in 2010...phase that SS, run it into the confluence, and it can only go so far N...a zwyts favorite: 40S special.

 

Very interesting look for sure. I hope this sticks around longer than the last promising pattern we saw...

 

what does this post add to the discussion? nobody cares what you hope for.

Excellent look for sure.  Similar looking -AO/NAO to what you showed earlier from the 00Z run (if I recall).  The precise details may "disappear" in 12 hours, but I think the main players have been showing up now for a little while.  And you're right...that confluence is something we haven't seen for some years.  At least that ideally.  Sort of a ridge-bridge forming there too?

GFS had a similar setup.  It's not hyperbole to say it's a pattern that could produce a KU.  Doesn't mean it will happen and it's not the first time this year we've had an advertised Day 10-15 pattern that's looked KUish.  Obviously none have materialized yet, but maybe we'll get lucky.  We could have a really nice stretch of winter starting today.

Exactly. Just something to pay attention to as we get past the next 2 events. haha

 

I just realized they added DC specific postage stamps to the euro ensemble members. This is total snow through the next 15 days for half the members. The other half look no different. Optimism is warranted right now.
