A stationary trough of low pressure centered over Nevada introduced strong westerly vertical shear to northern Arizona. This shear combined with the ever present monsoon moisture to produce numerous reports of severe weather across Yavapai county. The tornado 8 miles east of Chino Valley was observed to land in an open field and did no damage. Lightning started a house fire in Cottonwood.
