What the National Weather Service wrote
A shortwave trough rotating through the region led to steepening lapse rates and increasingly unstable conditions across central Arizona on the 16th. With abundant moisture and high CAPE values in place, the environment was favorable for the development of strong to severe thunderstorms. Thunderstorms initially developed over the high terrain of eastern Arizona before racing toward the west/southwest into the lower deserts of south-central Arizona as a line of strong to severe thunderstorms. The main impacts associated with these thunderstorms occurred as they moved into the Phoenix metro, producing widespread damaging wind gusts. Multiple observations recorded wind gusts in excess of 60 mph with a few approaching 80 mph. Recently implemented damage threat categories for Severe Thunderstorm Warnings were put to the test with one destructive Severe Thunderstorm Warning being issued for 80 mph wind gusts for much of Phoenix. There were numerous reports of downed trees across the Valley as a result of the severe wind gusts. The strong winds also led to several reports of dense blowing dust in dust prone areas. Additionally, thunderstorms produced locally heavy rainfall that led to several instances of flash flooding. No injuries were reported.
