Countdown to Winter 2018 -2019

Ventrice has an interesting product that also looks at low frequency forcing..IE where the areas of overall upper level divergence and convergence are. It will be interesting to see how Nino behaves in the Fall. Sometimes it doesn't line up with the anomalies and that sort of throws a wrench into things. 

I'm a fan of his work....that is not available for public consumption, is it?

I remember you referenced that earlier this summer when some were trying to call faux el nino event again....you cited that in disputing it.

Unfortunately it's his own stuff.  It's just another way of viewing it instead of the legacy SST anomalies. I think some of the faux Nino talk was also from some of the model forecast of SST anomalies. The Euro has had a big warm bias, but this time around the spread was much tighter. Also, the forecasts from previous months, and the actual values that the ensemble members started from...were fairly close. Another words, the Euro seasonal did not exhibit such a month to month warm bias like previous years had.

Last season it was already correcting cooler quickly at this point.

Steady as she goes this year-

Anyone with even a modicum of knowledge regarding ENSO snowfall climo would perceive these as conflicting assertions.

I agree that el nino will be weaker than 2003 and 2010, which favored the mid atlantic. Weak el nino events favor sne.....NOT further south.

That is wrong.

 

#1 I did say preliminary 

#2 I don't think Climo status quo. Just because there is a weak CP Nino it doesn't necessarily mean it all pans out status quo. For example we've had some warm CP ninos.

 

Other factors besides ENSO...especially a weak event

To me the low solar is really tasty when potentially paired with what may emerge from ENSO/EPO/NAO.  We should have a better idea in a month.

The great winters of the 60s featured a low solar period iirc?

I think so but we’ve had great ones with active suns also.  But my understanding is lower solar increases the likelihood of blocking in the NAO region.

Yes that’s my understanding as well. The authors at EasternMass blog do a great job explaining this stuff in their winter outlooks.

Some great minds over there...

JB has posted his winter outlook and once again he is calling for a cold and snowy winter in the east. Although he does seem to be leaning towards a "warm" Dec. I find his temp outlook map for the winter to be suspect.

I've read plenty regarding the correlation with the AO domain over all - not so much in quadrature/relation to it's subordinate EPO and NAO domain spaces... 

For the general reader .. the AO domain space ...as in the geographical area, extends evenly southward from the north pole in all directions.  

The EPO and NAO (which are crucial for North America's interests..) extend some distance north within the AO domain region ... but also extend much farther south well beyond the terminus of the AO.  

That means that at times the AO can be negative while the other two are concurrently positive, and vice versa...  particularly that can be true when time dependency is applied to the correlation. 

The causal link between low solar is total AO domain consideration ... how those intervals of blocking set up and whether those are in or outside the EPO and/or NAO is a secondary mechanism.  Since the AO does, however, share domain space, it's a probability related matter ... The AO may be in a blocked mode, and offers some favorability that its block happens to coincide with EPO and NAO. 

As far as targeting the NAO during solar minimum ...that may be, but I've never heard of that - it may actually be more precise to think of the blocking phases as a total hemispheric phenomenon, and then it's a (ironically) dice roll where -

#1 You didn't mention the rationale for potentially straying from climo...which at several months lead seems odd.

#2 First of all, name the weak modoki el nino events that featured above avg NE temps...secondly, you shifted the debate. My contention was favored area for max seasonal snowfall surplus, not temps. 2004-2005 may have been a bit mild, but take a look at there max snowfall anomaly was, which is the point.

It looks good right now, but I'm not ready to call it during the summer.......hell, I'm not even beginning to scrutinize modoki value until later this month.

I mean, this is akin to the Sox leading in the 3rd inning....can't declare victory...except maybe this season, apparently :lol:

But if that were to be the case.....the answer to your question is, yes. The prevalent n stream will increase the likelihood of a relatively large amount of late bloomers, as sometimes it takes the energy a bit longer (especially relative to modeling) to consolidate when the lion's share of dynamics are born of the n jet.

Here, James.

Another thing....if you want to argue weak modoki doesn't have to be cold....but then favor the mid atl for snowfall surplus? Probably not going to work....a mild weak el nino season is very unlikely to favor the mid stl....weak STJ fostering envt. ripe w Miller Bs, not to mention they need negative temp departures to snow. We don't-

Will the storm tracks shift far enough closer to the BM to give the weat of river folks at a slim shot of a KU? Just one...?

When I was just a little boy...I asked scooter what will it be.....will I be shoveling, will it be wet....here’s what he said to me...

que sera sera....whatever will be will be.....the weenie’s not ours to see....what will be will be....

At some point it will be longitude FTL for the coast.
