Multiple mesoscale convective systems developed in northwest flow aloft and tracked across the Mid-South. The first tracked from southeast Missouri and southwest Kentucky into West Tennessee during the early-mid afternoon on July 18th. The second mesoscale convective system developed over southern Missouri and tracked across northeast Arkansas, the Memphis metropolitan area, and north Mississippi. These systems were supported by a very moist and unstable airmass with surface-based convective available potential energy values exceeding 6000 J/kg and precipitable water values greater than 2 inches. Adequate amounts of wind shear aloft helped to organize storms as well. Numerous severe storms occurred across the Mid-South with a few reports of large hail and many reports of damaging wind. The Memphis area was among the hardest hit with power outages to over 130,000 utility customers in Shelby County.
