Excuse me. You missed a spot.

Whoa! Would you look at that! A polar air mass covering most of eastern Canada. That would normally be clear stable air... if it weren't for the Great Lakes. So, eastern Canada and the northeastern United States are getting a two stage snow storm.

It's called Lake Effect. Yes, it's happening later than it should and this year has been particularly heavy. That would be because the Great Lakes aren't as cold as they should be. That leads to more, not less, snow.

Whether you believe in global warming or not, I'd make sure you keep your snow shovel in good shape. From UCS:
... lake-effect snow may increase as a result of warmer lake surface waters and decreased ice cover, burdening cities with increased cost for snow removal.
Most people have already recognized that fact. Unless you think it's all a hoax.
