   VALID 101744Z - 101915Z

   CONTINUES.

   SUMMARY...DAMAGING WINDS WILL REMAIN THE PRIMARY HAZARD PARTICULARLY

   EAST-CENTRAL/NORTHEAST KY AS OF 1730Z. DOWNSTREAM DESTABILIZATION
   ALONG/SOUTH OF A WEST-EAST FRONT/ZONE OF DIFFERENTIAL HEATING AND A
   RELATIVELY STRONG WIND FIELD WILL CONTINUE TO SUPPORT DAMAGING WIND
   POTENTIAL PARTICULARLY ACROSS REMAINING PARTS OF
   NORTHEAST/EAST-CENTRAL KY INTO WV/EXTREME SOUTH-CENTRAL OH. THE
   LATEST WSR-88D VWP DATA FROM LOUISVILLE IS SAMPLING 40-50 KT REAR
   INFLOW BETWEEN 2-6 KM AGL.

   CURRENT FAR EASTERN KY BOW ECHO ASIDE...ADDITIONAL STRONG/SEVERE
   THUNDERSTORM DEVELOPMENT IS LIKELY TO CONTINUE TO OCCUR ALONG /AND
   PERHAPS EVEN A LITTLE NORTH OF/ TRAILING OUTFLOW THAT CURRENTLY
   EXTENDS SOUTHWEST-NORTHEASTWARD ACROSS CENTRAL/SOUTHWEST KY...WHERE
   MLCAPE IS BETWEEN 1000-2000 J/KG. CONVECTIVE TRENDS WILL CONTINUE TO
   BE MONITORED FOR THE POSSIBILITY OF AN ADDITIONAL SEVERE
   THUNDERSTORM WATCH AND/OR RECOMMENDATIONS OF SPATIAL EXTENSION.
