What the National Weather Service wrote
Favorable monsoonal conditions promoted the development of severe thunderstorms across the region on the 18th. Abundant moisture (PWATs of 1.7-2.0) and instability (MUCAPE 1,000-2,000 J/kg) was in place across south-central and southwest Arizona, while increased easterly steering flow from an upper level low over northern Mexico aided in thunderstorms propagating off the high terrain. DCAPE were around 1,000-1,200 J/kg which helped in allowing strong to severe thunderstorms to produce damaging winds from downbursts. Thunderstorms initially developed along the Mogollon Rim during the early afternoon hours before pushing into the lower deserts of south-central and southwest Arizona through the evening. No injuries were reported.
