   AREAS AFFECTED...CNTRL/SRN INDIANA
   
   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 
   
   VALID 172139Z - 172315Z
   
   PROBABILITY OF WATCH ISSUANCE...20 PERCENT
   
   SUMMARY...AN ISOLATED SVR THREAT WILL EXIST INTO THE EARLY EVENING
   HOURS. THE ISSUANCE OF A WW IS UNLIKELY.
   
   DISCUSSION...SCATTERED STRONG TO ISOLATED SVR STORMS ARE DEVELOPING
   NWD/WWD INTO A STRONGLY UNSTABLE AIR MASS LYING S OF A
   QUASI-STATIONARY FRONT EXTENDING FROM CNTRL INDIANA INTO CNTRL OHIO.
   LOW-LEVEL/DEEP FORCING FOR ASCENT IS WEAK...AND THIS SHOULD
   CONTRIBUTE TO LIMITED COVERAGE OF ANY SVR STORMS. REGARDLESS...WITH
   AT LEAST MODEST DEEP SHEAR -- STRONGEST NEAR THE SFC FRONT --
   OCCASIONALLY ORGANIZED CONVECTIVE STRUCTURES MAY ENSUE WITH SVR HAIL
   AND PERHAPS SVR WIND GUSTS. THIS ACTIVITY SHOULD WEAKEN DURING THE
   EARLY EVENING...AS NOCTURNAL COOLING CONTRIBUTES TO INCREASING CINH.
