A residual boundary left over from pre-dawn storms was located near the Tennessee/Mississippi state line during the morning hours of July 21, 2023. By early afternoon a progressive mid-level trough moved into the region on northwest flow aloft. Along and south of the boundary the airmass became strongly unstable with mixed-layer convective available potential energy values over 4000 J/kg and downdraft convective available potential energy values exceeding 1000 J/kg.  The approaching mid-level trough reignited storms along the boundary. A bow echo formed over eastern Arkansas during the early afternoon and raced east along the Tennessee/Mississippi border resulting in numerous damaging wind reports including widespread power outages in the Memphis Metropolitian area. This was the fourth time in four weeks that the Memphis area suffered widespread power outages from damaging wind. Over 60,000 utility customers in Shelby County lost power. As storms moved east they expanded southward across northeast Mississippi.
