In my opinion the trend of the solar cycle plays a significant role, and its ascending pretty quickly with regular activity.... coupled with a modoki la nina, which teleconnect to +NAO. Now, if la nina becomes more basin wide, them maybe I would soften my stance a bit. 2000-2001 is a decent analog and I am entertaining the notion of a solid ending, but we would need to see a major SSW manifest properly in order for a - NAO season to become more viable. I would not be shocked to see the AO average slightly negative and oppose the NAO a bit....kind of like what I suspect we may see in the Pacific in relation to the PDO/PNA.
I will get into all of this in more detail this fall.
