The above photo shows the trailing edge of a supercell thunderstorm, and accompanying mammatus clouds, which passed south of Avon, Indiana, during the evening hours of Friday, March 31, 2006. Mammatus can persist anywhere from minutes to hours, roiling, diffusing and disappearing over time. Breathtaking cloud displays such as these, which cause more alarm than damage, are great for people who love to do storm photography.
