   SUMMARY...A line of thunderstorms extending southwest to northeast
   along a cold front/surface trough have rapidly developed early this
   evening, with a couple of more robust updrafts noted near the KY/IN
   border. A few supercells will be possible over the next 3 hours.

   DISCUSSION...Enhanced surface convergence along a cold front near
   the KY/IN border has led to the development of a line of
   thunderstorms. An instability axis is noted along and ahead of this
   zone, where MLCAPE is around 2000 J/kg. Localized deep layer shear
   is sufficient for some storm organization, and a few embedded
   supercells will be possible through at least sunset. Waning
   instability through the evening, and a linear mode, should keep the
   severe hail threat localized. A severe damaging wind threat may
   accompany larger clusters or a bowing segment or two. Convective
   trends will be monitored for a possible watch.
