Dusty Sunday: Large thunderstorm complex sends outflows into Arizona

Did you notice the haze outside on this Sunday (August 10th)? It is all thanks to a very large complex of thunderstorms that developed just south of Arizona yesterday afternoon/evening. As this complex of storms collapsed, it sent out a large outflow, which brought gusty winds and blowing dust to many portions of the state (especially central, southern, and western portions of Arizona).

The satellite loop below is water vapor from August 9th at 5 pm to around 10 am on August 10th. Note the thunderstorm complex just south of Arizona, and later on the "waves" coming out of it in all directions. These "waves" are the outflows.
