   The severe weather threat for Tornado Watch 78 continues.

   SUMMARY...The potential for multiple discrete supercells and
   attendant tornadoes is increasing along an axis from southwest Ohio
   into central Kentucky and northern Middle Tennessee.

   DISCUSSION...Regional radars show a line of thunderstorms
   intensifying from southeast IN into west-central KY and northwest
   TN.  Multiple cells in this line have developed mid-level rotation
   in the past 45 min, with reported tornadoes in the storm west of
   Cincinnati.  Clouds have thinned ahead of this activity, where
   temperatures have locally warmed into the mid 70s along with
   dewpoints in the mid 60s.  A 50+ knot southerly low-level jet is
   aiding in impressive shear parameters, with VAD profiles showing
   0-3km SRH values of 300-500 m2/s2.  Discrete supercells in this line
   appear to be the primary concern for tornadoes (potentially strong)
   during the next 1-2 hours.  Steep mid-level lapse rates will also
   promote large hail in the stronger cells.
