The Monsoon season in the South West USA starts in Arizona around the beginning of July. The dry air circulation pattern that Arizona and New Mexico experience most of the year oscillates. The dry pattern gives way to tropical moist air flow from the south. In July the temperature on the desert region of Arizona can averages 110 degrees. When the moist current of air hits the super heated desert a number of weather conditions are bound to develop.
The moist air rises in the super heated desert air forming powerful thunder storms which can cause flooding, wind storms, hail and dust storms. The air flow continue north past Phoenix and hits the Mongion Rim, a geological escarpment that runs from south east to south west across most of central Arizona.
This miles high transition from the valley floor shunts the moist air up into the highest possible weather capable regions of the atmosphere. When the monsoon is active colosal thunder storms build like clockwork each day over specific regions of the rim country.
