The State of The AO is another factor that is taken into consideration during winter outlooks and the pattern that it shows, gives us an idea of where things may be headed. Right now I would say if you were to look at the AO pattern right now you should be a little concerned. The AO has hovered around Neutral to Positive most of the year. For an effective cold and snowy winter you want the NAO, AO to be Negative and the PNA to be positive. But right now I’m not all that concerned . As Forecaster Jason Shaulov mentioned in his outlook, things appear to be setting up in this regard like the Winter of 2009-2010. We shall See. My next update for my winter outlook comes out on either August 15th or on September 1st. Stay tuned.
