To me this person is saying the much ballyhooed SSW is not the player it has been touted to be starting 5/10 years ago. Even the Enso does not have the predictability it used to. Many of these indexes, with seemingly a new one being rolled out Every year, are really just an attempt to put a definition on the undefinable longer range weather patterns and responses. Yes we know negative NAo and AO is important but the rest of it all is largely variable and/or unproven. Models in the medium to longer range really Do Not predict weather but rather give varying examples of it. The best thing for mid Atlantic people to try and pin down is where is the cold air and can or how does it get here.
