Storm Clouds, Colorado

When I first spotted this storm, 17 mi (27 km) north of Fort Morgan, Colorado, it appeared to be a mesacyclone. However, by the time I gathered my photography equipment and drove toward it, I could tell that it had changed quite a bit and was no longer so threatening.  Photographer: Debi Bratrsovsky; Debi’s Web site

Nonetheless, the way the waning sunlight interacted with the fast moving storm clouds was breathtaking; indigo, ink and violet clouds swirling above a red-rimmed horizon. Note the rain shaft in the distance. Photo taken just before sunset on June 20, 2011.
