Noted in the general forum's ENSO thread.  I haven't spent a ton of time looking at ENSO, but this looks to be accurate via ONI going back to 1950.  All official Ninas have either followed an official Nino or are a part of a multi-year Nina event. 

 

So if one were to "forecast" ENSO based on the fact that there have been 15 tri-monthlies of neutral ENSO in a row, then one would be better off forecasting Nino or neutral.  And that's just taking this sole piece of data into account.

 

Is that the right way to read it, or am I totally off?

Yeah, in isolation, you would not forecast a Nina going on this climo information.

Dt going weak niño

We'll see about that. Mid-July plumes don't show anything of the sort unless you hug an outlier. Statistical average is very weak nina / cold neutral throughout and dynamical average is basically even steven give or take a few tenth's one way or another.

PDO will be more of a player this year than enso IMO. That and whatever persistent NH LW pattern decides to set up for December. I personally think this winter will be more front loaded than last (mostly in the temp department. who knows about snow).

I've been doing some digging lately and have found some interesting things but I haven't organized anything to post yet. One cookie of info is that the persistent pattern at high latitudes for the last 3 months is quite similar to 1996. This is significant in some respects and notsomuch in others though.

Start filling the sandbags in Fargo.

lol- I was serious in some ways but not really. Still, it's hard to ignore what's going on in the arctic this summer. Very persistent pattern similar to 96 and the only similar pattern since 96.

 

These height anoms are close in some important ways. 81-10 climo kinda screws the 2013 look because heights in general are higher around the globe now than 20 years ago. But I think this comparison and the current state of enso is something that shouldn't be ignored at the very least. This is totally contrary to my thinking that Dec 2013 will be aob normal but I have different reasons for that. I'm just getting warmed up for the fall...lol

eventually, we have to get a winter that goes against everything and ends up snowy in our parts...eventually

I think that's why this year will probably have some bad long range calls (or calls that are right for the wrong reasons). Especially the early ones. There is no dominant signal. I suppose you could say the PDO will assert itself the most over other larger scale influences but even then.

 

Expecting a big snow year goes against all the early signs. That's a fair call. Which months are cold/warm is more of a dartboard than usual. 

 

I'm not making any early calls this season. I'll end up changing my mind too much as we approach late November. We've basically had 2 non-existent snow winters in a row and even the one before it kinda stunk too. Things have a way of evening out regardless of everything else. I would love to see the low snow calls go up in flames during a 2 week lucky stretch in December. It can happen.

I'm feeling it this year....but I feel it every year so I've got to be right at some point

as for forecasting, in the last 3 or 4 years I've lost any faith I had in mets and doctors so I don't really care who forecasts what
