I'm guessing you're using the Koppen classification when you say "subtropical" and "humid continental"? There are some climatologists who group according to mean temperatures during a year, which, combined with current patterns of warmer weather in some areas of North America due to (I think?) the southward shifted current (I forgot which one. Look, I like the environment, but I only did environmental toxicology), means some of the other climate classification systems might be revising a bit.
But yeah, fair enough, New York is part of group A.
