   NWS STORM PREDICTION CENTER NORMAN OK
   0727 PM CDT FRI JUN 12 2015

   AREAS AFFECTED...CENTRAL IND

   CONCERNING...SEVERE THUNDERSTORM WATCH 294...

   VALID 130027Z - 130100Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 294
   CONTINUES.

   SUMMARY...ALTHOUGH A LOCALLY STRONG TO PERHAPS SEVERE STORM CANNOT
   BE RULED OUT ACROSS WEST-CENTRAL INDIANA THIS EVENING...THE OVERALL
   SEVERE WEATHER THREAT WILL CONTINUE TO DIMINISH...WITH NO NEW WW/S
   REQUIRED.  WW 294 WILL BE ALLOWED TO EXPIRE AT OR BEFORE 01Z.

   DISCUSSION...EARLY EVENING OBJECTIVE ANALYSES INDICATED MUCH OF THE
   PREVIOUSLY UNSTABLE AIR MASS HAS BEEN CONVECTIVELY OVERTURNED...WITH
   JUST A FEW STORMS CONTINUING IN EAST-CENTRAL IL TO WEST-CENTRAL AND
   SRN IND.  THESE STORMS HAVE FORMED WITHIN A ZONE OF WEAK LOW-LEVEL
   WAA.  HOWEVER...FURTHER BOUNDARY-LAYER STABILIZATION WITH THE ONSET
   OF NOCTURNAL COOLING AND THE PRESENCE OF WEAK MIDLEVEL LAPSE RATES
   /PER ILX/ILN 00Z SOUNDINGS/ AND WEAK DEEP LAYER SHEAR SHOULD LIMIT
   THE SEVERE WEATHER THREAT.
