   Areas affected...southern/eastern Indiana into southwestern Ohio and
   northern Kentucky

   Concerning...Severe Thunderstorm Watch 415...417...

   Valid 291959Z - 292200Z

   The severe weather threat for Severe Thunderstorm Watch 415, 417
   continues.

   SUMMARY...Although the organized cluster of storms is weakening,
   strong to severe gusts may persist with remnant outflow
   overspreading the region through 6-7 PM EDT.

   DISCUSSION...Latest trends in lightning data and radar/satellite
   imagery indicate notable weakening trends are underway with the
   southeastward propagating convective system.  However, the
   associated cold pool and rear inflow jet remain strong, and
   southeastward propagation has accelerated a bit further at up to 60
   kt near the apex of the bow echo in radar reflectivities.  Surface
   gusts to 60+ have been recently recorded in observation sites at
   Lawrenceville IL and Crawfordsville, Indianapolis IN.  

   These peak gusts, mainly beneath the lingering rear inflow jet,
   should begin to diminish more rapidly with further weakening of the
   convection during the next couple of hours.  However, at its current
   forward propagation, it may cross the remainder of southeastern
   Indiana, southwestern Ohio and the Blue Grass into Coalfields of
   central into southeastern Kentucky by 22-23Z.
