CP we can still have major snowstorms in March of course, but the double digit snowfalls in urbanized areas like NYC and western LI is nonexistent- the last one here was March 1993. It's easy to see why thats the case when you combine high sun angle with concrete.
I'm fine with it, as by March most of us are already in spring mode and a 6-8 inch storm is fine and considered exceptional by then.
