What does a potential El Nino mean for you?

Last month the Climate Prediction Center predicted ENSO neutral conditions through the spring of 2014 and a 50% chance of an El Nino developing during the summer or fall.  What does this mean for our temperature and precipitation patterns?  The maps below (top-temperature, bottom-precipitation) show the trends and anomalies associated with an El Nino.  In layman's terms, the left side of the maps below show the average anomaly from normal conditions, the recent trend of these anomalies, and the combination of the average anomaly and the trend.  The right side of the map shows the frequency (basically the confidence) that these results materialize in a given El Nino event.
