Here are a few storm chasing photos from May 26 in Kansas. For the full gallery from that day, you can check here: http://backingwinds.blogspot.com/2006/05/may-26th-chase.html I honestly have no idea why the rain came out purple in the first image. It was a 2 second exposure, so perhaps the color of the lightning mixed with the sunlight refracting off the hail or something. I've never seen purple rain before, unless you count Prince songs. Thanks for looking!
