since 2008-2009 winter.. we have had over 20 inches in central park every year.. and many years more than that by a lot.. except for the 2011-2012 winter season..
you made a post saying after january 19 what a odd date to set unless it fit in with your own agenda why not say january 1 or feb 1 why the 19th of january?
so the history of nyc snow is only since 2010 according to your post..we have had plenty of big snowstorms before jan 19.....we have had 13 snowstorms of a foot or more of snow before jan 19 and one day which i did not add happened on jan 19-20..
comparing march to january because of a few years we had decent snow in march.. their is no comparison in terms of cold or blizzard potential that can happen in january but not march...
