   NWS STORM PREDICTION CENTER NORMAN OK
   0113 PM CDT MON APR 28 2003
   
   AREAS AFFECTED...SRN IL/SRN IN/WRN KY
   
   CONCERNING...SEVERE THUNDERSTORM POTENTIAL 
   
   VALID 281813Z - 282015Z
   
   MCS CURRENTLY ACROSS WRN IL WILL CONTINUE TO MOVE EWD OVER THE NEXT
   FEW HOURS. ISOLATED HAIL OR WIND DAMAGE WILL BE POSSIBLE WITH THE
   STRONGER CELLS. ACTIVITY IS EXPECTED TO REMAIN TOO ISOLATED AT THIS
   TIME AND A WW IS NOT ANTICIPATED.
   
   LARGE-SCALE LIFT ASSOCIATED WITH A SHORTWAVE TROUGH CURRENTLY MOVING
   INTO IL WAS AIDING THE CONTINUED EWD PROGRESSION OF A MESOSCALE
   CONVECTIVE SYSTEM IN WRN IL. ALONG THE SERN EDGE OF THE MCS...A LINE
   OF STRONG CONVECTION WILL CONTINUE TO INTERACT WITH SURFACE
   DEWPOINTS AROUND 60 F. TEMPERATURES OVER THE LAST FEW HOURS HAVE
   RISEN INTO THE LOWER 80S INCREASING SBCAPE VALUES TO AROUND 1000
   J/KG AHEAD OF THE LINE. DEEP LAYER SHEAR WAS WEAK IN THIS REGION
   HOWEVER...IF THE MCS CAN REMAIN ORGANIZED AS IT INTERACTS WITH THE
   MARGINALLY UNSTABLE AIR ACROSS SRN IL/WRN KY...THE MULTICELLULAR
   CONVECTION WILL BE CAPABLE OF ISOLATED HAIL AND/OR DAMAGING WIND
   GUSTS OVER THE NEXT FEW HOURS. ACTIVITY IS EXPECTED TO REMAIN
   ISOLATED ENOUGH NOT TO WARRANT A WW AT THIS TIME.
