   AREAS AFFECTED...NRN KY...SRN/CNTRL OH...EXTREME NW WV

   CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 

   VALID 091751Z - 091845Z

   PROBABILITY OF WATCH ISSUANCE...60 PERCENT

   SUMMARY...GUSTY WINDS MAY ACCOMPANY MORE ORGANIZED LINE SEGMENTS AS
   THEY SPREAD INTO SRN/CNTRL OH.  A FEW SEVERE WINDS GUSTS ARE
   POSSIBLE...ESPECIALLY WITH BOW-SHAPED STRUCTURES.

   DISCUSSION...SEVERAL EMBEDDED WEAK MCV STRUCTURES ARE TRAVERSING THE
   MID MS/OH VALLEY REGION.  SUBSTANTIAL...BUT MOSTLY WEAK...CONVECTION
   IS NOTED AHEAD OF THESE FEATURES WITH A CONCENTRATION OF TSTM
   ACTIVITY NOW OVER SERN IND/NRN KY/SWRN OH.  THIS ACTIVITY HAS
   RECENTLY INCREASED IN INTENSITY AS BOUNDARY LAYER DEEPENED AND SFC
   TEMPERATURES WARMED INTO THE MID 70S.  DEEP SWLY SHEAR VECTORS FAVOR
   ORGANIZED LINE SEGMENTS AND BULK SHEAR CERTAINLY SUPPORTS THE
   POTENTIAL FOR GUSTY WINDS AND PERHAPS A FEW SEVERE WIND GUSTS. 
   GREATEST POTENTIAL FOR ORGANIZED SEVERE CONVECTION WILL BE ACROSS
   SRN OH WHERE SFC-3KM LAPSE RATES HAVE STEEPENED DUE TO
   AFOREMENTIONED BOUNDARY LAYER WARMING.
