   0122 PM CDT TUE JUN 15 2004
   
   AREAS AFFECTED...CENTRAL IN...CENTRAL AND SRN OH...EXTREME NRN KY /
   NWRN WV / WRN PA
   
   CONCERNING...SEVERE THUNDERSTORM POTENTIAL 
   
   VALID 151822Z - 152015Z
   
   ISOLATED SEVERE WIND GUSTS AND MARGINALLY SEVERE HAIL WILL BE
   POSSIBLE THROUGH THE AFTERNOON.  A WW IS NOT ANTICIPATED.
   
   SURFACE ANALYSIS SHOWS E-W ORIENTED FRONTAL BOUNDARY WHERE AIR MASS
   IS MODERATELY UNSTABLE.  OUTFLOW BOUNDARY FROM EARLY MORNING
   CONVECTION INTERSECTS THIS FRONT OVER EXTREME WRN IN AND IS CAUSING
   STORMS TO BECOME LOCALLY ENHANCED DUE TO STRONGER FORCING.
   
   ALTHOUGH LOW TO MID LEVEL WIND PROFILES ARE NOT FAVORABLE FOR LONG
   LIVED CONVECTION...STORMS IN VICINITY OF OUTFLOW BOUNDARY /
   STATIONARY FRONT INTERSECTION ALONG WITH MARGINAL 20-40 KT MID TO
   UPPER LEVEL FLOW SUGGEST STORMS IN THESE AREAS WILL BE THE
   STRONGEST...AND WILL PRODUCE ISOLATED HAIL AND WIND AS THEY CONTINUE
   TO DEVELOP AND PROPAGATE EWD ALONG FRONT.
   
   FURTHER E ALONG FRONTAL ZONE...MOST PULSE CONVECTION WILL REMAIN
   BELOW SEVERE LIMITS...BUT ISOLATED AND BRIEF SEVERE STORMS ARE
   POSSIBLE.
