With the subtropical high pressure situated across central New Mexico, a southeasterly wind flow was established across Arizona. Thunderstorm activity developed across portions of southeast AZ during the afternoon hours. MLCAPE between 500-1000 J/KG as well as Downdraft CAPE near 2000 J/KG aided in creating a favorable environment for the thunderstorm activity to result in strong downburst winds. The first thunderstorm activity to develop across portions of southeast AZ resulted in the development of a strong outflow boundary, responsible for dense blowing dust conditions across Pinal and southern Maricopa Counties as well as sparking additional storms that affected portions of the Phoenix metro area. With the thunderstorms that moved across the Phoenix metro area, there were several reports of tree damage as well as structural damage to several homes.
