Real +PNA doesn't get going until Oct 16th now, and then it appears short-lived. 

On the latest ens runs, +PNA looks to get established just prior to mid month, and then lock in for the next week(through the end of the run). A bit of an EPO ridge too.

BAMwx on Twitter also mentioning a recurving WPac typhoon that would reinforce an eastern trough late month potentially.

You captured the core +PNA there. Compared to what models were showing, it's much later developing, and not as strong. They originally had Oct 8-9 as the start of it, now it's a sheered out at that time. It's in prime position for 3-4 days then it breaks down. I have to think the PDO making a run a -3 right now, which is near record, has somewhat of a reason why it trended less impressive.

GFS predicts heavy snow in mts. of W.Va. Oct. 23.

I love the snow maps as much as anyone, but to keep the snow map police at bay, couple of pointers, outside 5 days, the global snow maps are worthless,  at 3-5 days they may be onto something if there is more than one global model supporting the scenario.  Outside 5 days look for any trend on the ensembles.  In this case, no real GEFS support at range.

Thanks Will. I understand completely. 384 hrs is wishcasting regardless of the source.  A month or 3 months or 6 months is also wishcasting, even more so.  There are many posts that do not pass reasonable scrutiny. As far as Snow Map Police, I couldn't care less. They are only foolishly criticizing a guessing game that they are addicted to.

I look at the CFS and ECMWF longrange stuff occasionally as well as the Cansips and others. Some really put high hopes on or even debate micro elements in something that changes tomorrow or next week or next month. To me it is little more than trivial distraction.

It was just a quiet Sunday morning and I decided to post something rather unusual for this early date.

Here we are are looking at 12z and its gone!!!!

What is the advantage of seeing this in October over November?

GaWx in the SE forum sniffed out a partial correlation between BN Oct and BN winters in the SE up to MA. He made a very convincing case to root for a cold Oct over a cold Nov. 

I’ve also anecdotally observed that cold Novembers usually lead to milder winters especially in ninos.

What does this really mean????

I *think* it means that, if we want a better shot at below normal temps in winter, then we should root for a chilly October rather than a chilly November, but perhaps my reading comprehension isn't as good as it once was.

That’s pretty much it. I shared the above threads because they had the numbers to back it up.

I am beginning to be concerned more about precipitation than temperatures. An historical Nino gives heavy precipitation to the Carolina's and south with Va/Maryland being on the northern fringe.  Nearly all current guidelines suggest this may be a suppression winter when we so desperately need heavy precipitation for the widespread drought, especially western areas.

They do? It does?
