Remnants of Laura Produced Two Tornadoes on On the afternoon of Aug 28 2020, the remnants of tropical system Laura moved eastward across the Tennessee and Ohio Valleys with a trailing surface boundary across portions of the Deep South. An abundance of tropical moisture coincided with areas of diurnal heating to promote an unstable atmosphere which also interacted with areas of favorable low-level and deep-layer wind shear. As a result, an environment favorable for the development of strong to severe thunderstorms established across a good portion of the Mid to Deep South, including Central Alabama. Strong to severe thunderstorms developed in the vicinity of southern Tennessee and northern Mississippi which tracked generally eastward during the mid afternoon, impacting various areas of northwest Central Alabama. Damaging straight-line winds produced several areas of tree damage as a line of thunderstorms moved across these areas. Additionally, two low-topped supercell thunderstorms moved ahead of this line and generally east-northeastward into Winston County in the late afternoon. These rotating thunderstorms were able to re-intensify and went on to produce two tornadoes, both of EF-1 strength, with the first near the Grayson and Moreland areas, and the second in the Double Springs area of north and central Winston County. |
