   The severe weather threat for Tornado Watch 60 continues.

   SUMMARY...A concentrated corridor of supercells is expected across
   portions of the Mid-South this evening.

   DISCUSSION...LLJ is shifting southeast early this evening along the
   southern fringe of a trough that is shifting towards the lower Ohio
   Valley. Large-scale synoptic front is expected to advance across
   western KY/TN/eastern AR, but pre-frontal confluence appears to be
   aiding scattered-numerous robust updrafts, including supercells,
   along a corridor from southeast AR-northern MS-northwest AL. Most of
   the longer-lived updrafts are producing hail and this should
   continue into the mid-evening hours. Additionally, forecast
   soundings suggest some tornado risk where dew points have risen into
   the lower 60s, as SBCAPE in this environment is fairly substantial
   within a strongly sheared environment. With time this corridor is
   expected to gradually sag southeast.
