In and around EarthSky’s hometown of Austin, Texas – and, in fact, up into Oklahoma and other parts of the central U.S. – there was some catastrophically bad weather over the Memorial Day weekend. Those who look skyward also noticed lots of mammatus clouds over a period of several days, like these clouds captured by Anne Marie in Georgetown, Texas. These ominous but beautiful clouds can appear around, before or after storms. Anne Marie appears to have caught them as the clouds were breaking up, just as the sun was going down. She wrote:
