U.S. Fall Weather Outlook

September begins meteorological Fall in the U.S.  It’s a time for colorful forests, football, pumpkins, crisp morning air, and the excited anticipation for (or dreaded fear of) the oncoming Winter.  Of course, Winter outlooks get much of the attention in the forecasting world.  Everyone wants to know just how terrible the upcoming snowy season will be – terrible can be good or bad depending on your point of view.

We’ll spend plenty of time looking at Winter 2009-10 in the coming months (and hours), but I thought it would be worthwhile to take a moment and look at the Fall outlook from the Climate Prediction Center (CPC).  Below are similar maps to those found in the September outlook post.

No areas are expected to experience below normal temperatures this Fall after the cooler than normal Summer.  In fact, a significant portion of the country is expected to have above normal temperatures this season.  The wet areas are expected to be along the Gulf coast, Alaskan coast and in the northern High Plains.  The Pacific Northwest is expected to be drier than normal.  The “EC” label indicates Equal Chances for basically anything to occur relative to normal.  Once again, if I remember, we’ll review this forecast at the end of Fall and during the season as the situation warrants.
