Dr Jeff Masters, who created Weather Underground, has a “year in” post on the weather of 2012. Which also tells the story in this remarkable video, showing a year in weather over the US in just 3 1/2 minutes (it slows down for some of the more dramatic events, which are kind of amazing). The Derecho that took out power in West Virgina, Virginia, and DC is by far the most amazing.
