*Key point in the latest discussion out of the Climate Prediction Center:  A strong El Nino is NOT likely this fall/winter in the U.S.  The upcoming El Nino event is expected to be a weak one, meaning other factors may offset it, so although above average temperatures are still being predicted this winter in Minnesota, don’t bet the house on that forecast yet.

*U.S. Seasonal Drought Outlook released September 20th, 2012.  This is valid through December 31st, 2012.  Quite a change between the last update a few weeks ago compared to this one.  The drought is now forecast to persist or continue to develop in most of Minnesota and Northwest Wisconsin.
