Lightning 072

A very powerful, single, cloud to ground lightning bolt from a summer thunderstorm strikes the foothills of the Rincon Mountains, east of Tucson, AZ with a power plant substation in the foreground..Awesome and intense thunderstorms with powerful gust fronts, heavy rain, hail and lightning are common over the Arizona Desert during the summer months. Southwestern weather patterns create thunderstorms by pulling the fuel, moist air, either from the Pacific Baja side or the Gulf of Mexico and mixing it with the dry hot air rising up from the heated desert floor. Lightning is beautiful, but dangerous.
