Yes, it does rain in Arizona. Between June 15th and September 30th (the official monsoon season in Arizona) storms may occur. These storms occur during the summer months throughout the southwest region of North America caused by a change in the wind flow to a southerly or southeasterly direction. That causes moisture to stream northward from the Pacific Ocean and the Gulf of Mexico. Monsoon storms can range from minor dust storms to violent thunderstorms. They usually start with heavy winds that sometimes result in a visible wall of dust hundreds of feet high moving across the valley. Or, they can be like the one I photographed last night, a little bit of wind and some very welcome rain. Best of all, the temperature cooled down to a balmy 75 degrees!
