The National Oceanic Atmospheric Administration (NOAA) climate scientists are predicting that the La Nina that we had last year will continue to be a multi-year phenomena and may increase in strength this fall. The current La Nina is not as strong as it was last September but one half the models predict it will strengthen this fall and winter. This will place our overall winter weather as drier and warmer than usual. This doesn't mean that we might not get a cold freezing blast but it means that for the most part the overall seasonal weather will be averaged to be warmer and dryer.
