As mentioned earlier, the relationship between El Nino and weather/climate in New England is not very strong.  The Climate Prediction Center does have a webpage that shows U. S. seasonal composites of temperature, precipitation, and snowfall that may be of interest.  However, there is no level of significance associated with these composites, other than the frequency with which these departures have occurred in the past.  These figures do show a tendency for snowier El Nino winters New England.
