This was the second of two storms to affect the area in just over 24 hours, leading to an overall two day total of 0.53in.. A high pressure system located over Northwestern Arizona allowed for a northeasterly flow over the valley, which allowed storms that formed in the higher terrain north and east of the valley to move into the lower elevations during the afternoon and evening hours.

Around 5:00pm, thunderstorms formed in northeastern Pinal county and were moving slowly toward the west. At the same time, an outflow was moving to the south from weakening thunderstorms in Northern Maricopa county. Around 6:15pm, the thunderstorms made there way into and through the Gold Canyon and Apache Junction areas. Also, the outflow, as mentioned earlier, was moving through the area at the same time the thunderstorms were, which caused a slight strengthening of the thunderstorms, especially in the Apache Junction area around 6:40pm.
