On Saturday, May 31, there was a spectacular thunderstorm in the Washington, DC area. It roared in with a front cloud and that ominous greenish sky color that means tornado warning. I was at a shop and there was no place to hide, so I and the other shoppers just watched it on the sidewalk until the deluge and the crashing lightning got too intense. Then we went inside, but the shop lost electrical power. I did this image of the oncoming storm from memory in Photoshop.
