A moist southeast airflow increased precipitable water values to over 1.75 inches. Thunderstorms developed over much of southeast Arizona. Storms produced heavy rain and flash flooding over Pima and Cochise Counties. Damaging winds occurred in Cochise County and strong outflows in Pima County created a dust storm that tracked northwest across Ironwood National Forest.
