It means that the chances for Southern California to have deficient rainfall is lower than it would be if we still believed a La Nina would be coming. The new set of seasonal forecasts for winter will be issued next Thursday (see http://www.cpc.ncep.noaa.gov/products/predictions/90day/ ) and they will likely show a lower chance for the "below normal" rainfall category due to the weakening in the outlook for La Nina. It is good news for you. But I know your drought is serious and getting a healthy rainfall season is important, so we need more than just making a poor rainfall outlook more of a normal one.
