What the National Weather Service wrote
As the region transitioned out of the monsoon, a compact low created a high shear - modest CAPE environment. Parameters were sufficient for supercell development and a few supercells did develop amongst isolated to scattered storms in the afternoon across South-central Arizona, including a right-mover that pushed into Phoenix and a left split. The environment was supportive of severe to large hail with lower freezing levels and steep mid-level lapse rates. Measured hail stones up to 1.0 to 1.5 diameter was observed with the few supercells. Most other storms also produced smaller hail throughout the day. Damaging winds and isolated flash flooding was also observed through the afternoon.
