Southern Arizona's weather

Southeast Arizona has some of the most interesting weather during its summer monsoons. The almost daily thunderstorms are as intense as you will find. Lightning storms usually precede the heavy rain starting in early July and lasting until early September. This weather pattern is caused by moist air moving from the gulf into the deserts of Mexico and moving northward into New Mexico and southern Arizona. Below is an example of some of these storms.
