   AREAS AFFECTED...PORTIONS OF SOUTHERN IND...SOUTHWESTERN OH...AND
   NORTHERN KY

   CONCERNING...SEVERE THUNDERSTORM WATCH 258...260...

   VALID 152301Z - 160000Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
   258...260...CONTINUES.

   SUMMARY...DECREASING THREAT FOR SEVERE WIND GUSTS THIS EVENING...AND
   NO NEW/DOWNSTREAM WATCH ISSUANCE IS ANTICIPATED.

   DISCUSSION...RECENT MRMS DATA DEPICT A CONSIDERABLE DOWNWARD TREND
   IN CONVECTION ACROSS MUCH OF WW 260 AND NRN PARTS OF WW 258...AS
   STORMS ENCOUNTER A STABLE AIR MASS IN THE WAKE OF A CONVECTIVE
   SYSTEM TO THE SOUTH. INDEED...THIS TREND IS LIKELY TO CONTINUE OVER
   THE NEXT FEW HOURS. THE GREATEST POTENTIAL FOR A FEW SEVERE GUSTS
   WILL LIKELY BE OVER FAR NORTHERN KY AND SOUTHWESTERN OH...WHERE THE
   AIR MASS AHEAD OF A BOWING CLUSTER REMAINS SOMEWHAT MORE PRISTINE.
   HERE...STEEPER LOW-LEVEL LAPSE RATES MAY ENHANCE DOWNDRAFT/COLD POOL
   POTENTIAL...MAINTAINING A NARROW WINDOW FOR STRONGER WINDS.
   NONETHELESS...EVEN HERE CONVECTION SHOULD GRADUALLY WEAKEN OVER THE
   NEXT FEW HOURS...AND DOWNSTREAM WATCH ISSUANCE IS NOT ANTICIPATED.
