Overview

Just one week after severe storms brought 6 tornadoes and significant flooding to southern and eastern Middle Tennessee, another storm system spawned another round of severe weather and heavy rainfall in the same areas on February 12th. A line of strong to severe thunderstorms called a QLCS (Quasi-Linear Convective System) developed during the afternoon hours across southwest Middle Tennessee and northern Alabama, then moved northeast producing widespread straight-line wind damage and one confirmed tornado in Lawrence County. In addition, heavy rainfall caused more flooding in many parts of the region.
