Thunderstorm Wind in La Paz County, Arizona

Report from trained spotter described window broken from north side of the local post office and roof damage at LNWilliams Engineering and Mining Manufacturing Building. Both of these buildings located along US-60 in the town of Salome. Winds were estimated at around 60 mph. Timing estimated from radar. No injuries were reported.

An abundance of moisture (PWAT 1.5+) and moderate to high instability (MLCAPE of 1000-2000 J/KG) led to the development of terrain and diurnally induced thunderstorm activity. Thunderstorms first began to develop across portions of southwestern Arizona during the early afternoon hours and thereafter, additional storm development occurred across the higher terrain east of Phoenix. Outflow from storms, particularly across the higher terrain east of Phoenix led to the development of more storms across portions of the Phoenix metro, particularly in the area between Chandler and Queen Creek.
