I'm across the Potomac in Arlington. It was an impressive little storm. I was commenting to some neighbors about being glad that I wasn't one of the couple of thousand people that were probably crowding into the Lincoln Memorial right about then. Our power went off for a couple of hours.
I'm in Florida and we're used to heavy thunderstorms, but that was a real frog choker if I ever saw one. The wind was whipping and they said they had to open government buildings to provide cover for the crowds on the Mall who were waiting for the fireworks and show.
