2005 was the worst...I remmber that May, I was commuting my first year at UML...it was a blustery nor' easter with temps in the 40s like every weekend.
Assuming a high ACE/La Nina, really the only subpar season is 1998-1999...and once you get above 200 ACE they are all decent...2005-2006 probably being the floor.
DT pulled the plug like a week or two ago....last year he pulled the plug in December....he is more focused on data interpreation than long range predicitng, though.
Especially after next year we are going to enter into a stretch of a few years that will not feature much high latitude blocking at all IMO, so the extra tropical Pacific needs to improve.
It will be less favorable for blocking next year, but if the ACE gets very high, then the extra tropical Pacific should be at least a bit better....otherwise, find a new hobby.
Clearly....
But if your point is that CC doesn't prevent the aggregate of the spring season from sucking around here, then sure...I agree. But it most certainly will mean a few more bum-warmers in the car. Just keep in mind that the magnitude of warming necessary to dramitcally impact the weather is much less than that which is needed to be readily palpable to the masses.
