For many years, I had hoped that there would be some weird, surprising reason why a warmer earth produces more snow for my back yard. “Jetweirding” producing more high latitude blocking! Late season snowicanes like Sandy (minus the destruction ideally, though I’ll take some beach erosion for a tropical snowstorm in early November)! And honestly, the jury is still out! We still don’t have the data to say. But the last few years have been dispiriting. And the simplest answer is probably the correct one: warmer seas are pushing the thermal boundary inland. Less snow cover in our cold air source regions means less cold air here. The end.
