   Concerning...Tornado Watch 57...

   Valid 140920Z - 141115Z

   The severe weather threat for Tornado Watch 57 continues.

   SUMMARY...The threat for tornadoes and wind damage continues for WW
   57.  A new tornado watch may eventually be needed downstream after
   1030-1100Z.

   DISCUSSION...A broken band of convection continues near the I-65
   corridor from middle Tennessee into central Alabama currently.  A
   few of these storms have exhibited signatures consistent with brief
   tornadoes - most recently in Shelby County near BMX.  These storms
   continue in a strongly sheared, yet weakly unstable environment,
   with enough instability present to maintain the severe threat
   through the eastern extent of WW 57.  An estimated 230/45 storm
   motion should take these storms toward the eastern end of the WW
   around 11Z or so, and a downstream tornado watch issuance will
   probably be needed.
