Episode narrativeepisode_narrativeStrong to severe thunderstorms developed in an unstable atmosphere in the afternoon of the 22nd. Storms initially developed over the high terrain of northern and eastern Arizona as well as near the Table Top mesa area south of Phoenix. High DCAPE promoted strong thunderstorm downbursts. The downbursts generated outflows that progressed into the greater Phoenix metro area and led to the development of additional scattered thunderstorm. The thunderstorms in the metro area produced damaging winds that led to numerous downed trees, downed power poles, and other property damage. The storms were also nearly stationary, under weak steering flow, and produced very heavy rainfall with rain rates around 1.5-2.0 inches per hour and briefly higher in the strongest storms. This led to considerable flash flooding around Phoenix with several road closure and significant flow in major washes. Even after the strongest storms in Phoenix subsided in the late evening of the 22nd, areas of moderate to heavy rain continued from northeast to southwest through the night and through mid-afternoon on the 23rd. The continued rain through the 23rd was aided by a strengthening diffluent flow regime between the monsoon high to the north and a retrograding upper low moving west through New Mexico. Additional significant flash flooding was observed on the 23rd, mostly in the foothills north of the Phoenix metro, with many road closures, flowing washes and creeks, and some water rescues.
