Incredible Giant Mushroom Cloud over the City 
While helicopter pilot Andrew Park was flying over Phoenix this week, photographer Jerry Ferguson captured what appears to be a giant foreboding mushroom cloud hanging over the city.
In actuality the scene is a weather cluster called a “microburst,” a phenomenon that occurs when cooled air from a thunderstorm rushes to the ground and spreads over the land at speeds over 100 miles per hour causing a powerful and centralized air current.
