Just for people out of the South wondering why this storm is so bad, our winters are normally pretty wet but it's mostly rain. It's not unusual for us (say, near Atlanta) to get a two or three inch snow storm. (I've actually heard reports that we get as much or more precipitation than the Pacific Northwest) But this storm was presaged by about two weeks of really dry, freezing cold weather. When we get snow, it never accumulates on road surfaces, the moisture on the blacktop coupled with a usual warm trend keeps it from happening.
This storm was the perfect trifecta of cold, dry and snow. It turned our roads into ski rinks. I didn't know if this was being talked about so I thought I'd put it out there in case anyone was curious.
