Will this La Nina, if it does indeed happen, kill the warm PDO we have had for the last three years? When is this big flip back to cold PDO that Bastardi goes on about supposed to happen?

A positive PDO alone doesn't mean the eastern Eastern US/Midwest gets cool summers.
Strong (+1) positive PDO years during the summer
1902
1913
1926
1936 supper hot
1940
1941
1942
1947 August was super hot
1958 very cool June
1983 super hot
1986
1987
1992one of the coolest summers on record
1993
1995 super hot
1996
1997

So based on a positive PDO alone I don't detect any consistent pattern for us...
Am I reading that chart correctly? As of March 2016 the eastern-equatorial pacific is already -0.5 C below normal? If so this will be a killer La Nina.

Sub- surface temps, not surface temps. Surface temps stil 1.5C+ above normal. The cold underneath is important as it will continue to upwell and cool SST's

Aha see that now.
From SST, it looks like another 1982-1983 year if we continue along that projection.
From Sub-Surface it looks like one of the worst La Nina events in history, I wonder how those two will be reconciled.

I would love an 83' La Nina event. Hot summer, and coldest December on record

That would depend on how much and how fast the upwelling occurs. IMHO, I tend to believe that the pendulum swings both ways. This Super Nino may in fact turn into Super Nina.
