for NAO?
I thought we wanted east-based -NAO? With west-based -NAO you run the risk of above-average heights ticking New England which is why if you look at some -NAO composites parts of Maine actually see above-average temperatures. West based also keeps the brunt of the colder airmass into the upper-Midwest with a storm track west of us.
gotcha...thanks or this information!
ughhh one of these days I can get back into this stuff.
