Mid-level flow of 25-30 kts and divergence aloft combined with sufficient MLCAPE of  greater than 1000 J/kg to result in an environment favorable for the development of organized severe thunderstorms. A cluster of thunderstorms developed across southeast Pinal County during the late afternoon hours and moved northwestward through the Phoenix Metro after dark while becoming severe in the process. One of the more significant damage areas was along SR-87 in Salt River Reservation Community, where a mobile home and trailer park were destroyed and large transmission lines were downed. Power was knocked out for some for more than 2 days. A large dust storm also impacted parts of Pinal County.

Numerous power poles were blown down as well as several transmission towers that had collapsed. The transmission towers were in an area west of Gilbert Rd and along Highway 87. Salt River Project (SRP) utilities confirmed a total of 16 power poles were either blown over or snapped. They also confirmed another 5 (230 volt) transmission towers had collapsed. Other less severe damage was widespread across the region that included shingles blown off numerous homes, tree damage and damage to road signs. 20 other homes were listed as inhabitable.
