Winter storm snowfall levels: See online how many inches have fallen nationwide

Winter is here, and that means snow! Just how much snow? Well, back in the day, after a big snowfall, you'd need to whip out the ruler or yardstick and actually trek out into the white winter wonderland. And with a huge winter storm set to blanket much of the South and Northeast this weekend (200 million Americans are expected to see snowfall), this isn't a rhetorical question.

Nowadays, thankfully, you don't even have to go outside to see just how long you'll be digging out your car or shoveling your walkway.
