A very unstable environment along with an approaching weak surface trough dropping through Tennessee ignited several supercell thunderstorms during the mid afternoon through mid evening hours.  A couple of the supercell storms tracked from southern and southwester middle Tennessee through northwest and north central Alabama, producing long swaths of large hail, in some cases very large hail up to tennis and softball sized.  One of the storms produced a narrow swath of damaging winds across eastern Lawrence County, including the Speake community.  The winds destroyed a barn and garage, and knocked several trees and power lines down in this area.
