It snowed a few inches, then sleeted on top of it for hours. The sleet caused the snow to compact, and by the time it was done, a shovelful of the stuff weighed 50 pounds. People were breaking it up with metal shovels and building igloos out of it. Big highway plows on dumptrucks were riding right over the top of it. The only way to move it was with those little skid steer things with shovels on the front. Even they would get jammed up under it and their front wheels would come off the ground.

Cities dug the stuff up and put it in dumptrucks and took it to places like the parking lots of sports arenas and piled it three and four stories high, and it didn't completely melt until, like, May. I forget where it was, maybe Baltimore, where the snow/ice pile was so heavy it cracked the surface of the parking lot it was piled on.

Someone remarked that his yard looked like the Shackleton Expedition.

Oh, and this was in the midst of several days of overnight lows in the single digits and days in the teens.
