Really interesting stuff, the theme of Metro DC snow has always been razor thin since as long as I've been here, but back in the day it would break our way seemingly more often. I wonder what kind of affect global warming as a whole has on our region; we can't exactly afford a 1-2C degree increase in most storms, and it seems like we just can't push through any more to just get under freezing. I feel like I'm living in the southern St. Mary's Co of 20 years ago, if that makes any sense.
