Another look. Webb may have a meltdown because JAN/FEB is rocking! Typic warmish Nino DEC.

FWIW, Euro drastically changed NOV from it's previous forecast. So keep in mind a lot can happen in a month that the models cannot foresee. 

 

I love this look. This evolution is really textbook EL Nino and especially textbook for Nino's pre 1980. I know there has been a lot of work done with Modoki EL Nino's and I have read some papers, but I still want to explore this all further because it is quite intriguing how much EL Nino evolution has changed since the early 1980's. Is it solely due to the emergence of Modoki EL Nino's which have become more common? It's possible, but I don't think it's a sole driver.

He should worry about CC screwing up his preconceptions of telecon layouts during winter.  With faster flow velocity appearing to be an unavoidable rapture that warps the standard R-wave residences ( size, location and time) Siberian doesn't mean the same thing as it did the 1990s.

Forky likes warmer weather like Snowman19 and Torch Tiger do.

Eh.  I think he leans into CC every time we have a warm spell and lets face it, there a lot of warm spells to chirp over. Gets old.

However when it comes to a winter storm he will call balls and strikes fairly.  Good met, if a little cantankerous.

If we can maintain this massive warm pool driving the -PDO through winter I think that is going to bode very well for us. It doesn't even have to remain this intense...even if it were to weaken

Obviously the PDO has been negative for quite some time and these warm anomalies have been a fixture for quite a while. This has helped to maintain very strong ridging just west of the Aleutians

I was looking back at past EL Nino winter's which presented this 500mb height anomaly structure. The reasoning is as follows:

The ridging west of Aleutian is yielding a persisting troughing feature within the Gulf of Alaska domain and we should continue to see this strengthened as the Aleutian Low strengthens (typical of a Nino). The Aleutian Low can make us and it can break us, but past years

1913-1914

1940-1941

1957-1958 (BIG FAVORITE OF MINE FOR AN ANALOG!!!!!)

1958-1959

1965-1966

1968-1969

1994-1995 (no please but also the Aleutian Low was rather south and we had a raging +AO)

2009-2010

all featured persisting troughing within the Northeast and also favored blocking (exception of 94-95). 

I am on board for some major blocking periods this winter. I mean look at those height anomalies spanning the Arctic across the hemisphere...things to me seem to be setting up nicely. 

While I do think Dec could be a typical EL Nino like month...I would not set this in stone yet.
