The weaker the nina, the better chance of seeing a KU storm. If the index is below -0.9 for any three month period the chances are lower for a KU storm. Only three official nina winters out of twenty had a storm 8" or more. The four of five almost nina years had a storm 8" or more. When the index was -0.8 or higher NYC saw two of six years with KU storms. Not including the almost nina years. Only three of the 20 nina winters had above average snowfall...One year was near average and the other 16 were below average... Precipitation for nina winters...

Many of these years had at least one dry month. Most of the years had below normal snowfall and only three years had a snowstorm 10" or more. 1973 and 1983 had the most precipitation but both years had a record or near record wet month of December. Both years did have a dry month also which were also their coldest months of the winter. Link to comment Share on other sites More sharing options...

The "big snow" exceeds the snowfall for any month during that winter. Unless of couse the storm happened to be spanning February 29 to March 1. Is that what happened? From what I can tell from the records that's unlikely. Link to comment Share on other sites More sharing options...

Just think if it wasnt for the silly little leap day, it would have been an all March event..... I know that your reasoning is that Feb and Mar will both be above normal, but arent cold and snowy Marches more likely in a la nina? Link to comment Share on other sites More sharing options...
