I lived in the lower Hudson valley for 25 years, as well as the DC suburbs and the elevations of northern MD. I’d take NY climo any day of the week if we’re talking about the average winter versus DC. It’s just easier to snow up that way. NYC sometimes deals with more maritime issues being directly on the Atlantic, but generally speaking, it’s much better than DC. Maryland is weird though, cause I’d take my climo in northern MD over NYC. I saw over 50” a few years ago while DC didn’t hit double digits. 30-40 miles makes all of the difference down there. The one thing I will say is… the biggies that do work out for the mid Atlantic typically jackpot down there (January 2016 or snowmaggedon in 2010 for example)
