A cluster of thunderstorms developed across southwestern portions of the Phoenix area, near the Avondale and Goodyear area and then migrated northeastward into the north Phoenix and Scottsdale areas. With MLCAPE values between 500-1000 J/KG and DCAPE values of 1000 J/KG, it was enough to support isolated damaging wind gusts. In addition, with PWATs of around 1.5, the environment was sufficiently conducive to support some heavy rainfall rates as well, in excess of 0.5 per hour.
