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 in central and southern California due to the weakening in the outlook for La Nina. In the Pacific Northwest it could mean a reduction in the likelihood of above normal rainfall. In general, the teleconnection pattern associated with La Nina will probably be weakened, and will show less areal coverage. But you should check the forecast next Thursday, since there are other factors determining the West's winter climate besides ENSO, that the dynamical model predictions should pick up.
