SPC MESOSCALE DISCUSSION 0925 FOR SRN IND / SRN OH / NRN KY
   CONCERNING...SEVERE THUNDERSTORM POTENTIAL...
   
   VALID 281722Z - 281900Z
   
   ISOLATED STRONG TO SEVERE STORMS WILL BE LIKELY THROUGH THE
   AFTERNOON OVER SRN IND INTO SRN OH AND NRN KY.  HAIL/DAMAGING WINDS
   SHOULD BE THE PRIMARY THREATS.  WW NOT ANTICIPATED DUE TO ISOLATED
   NATURE OF STRONGEST STORMS.
   
   LATEST SURFACE ANALYSIS/VIS IMAGERY SHOWS A SWD MOVING LOW-LEVEL
   BOUNDARY NOW EXTENDING FROM 15 NE BMG TO CVG TO NEAR ZZV.  AIR MASS
   HAS BECOME MODERATELY UNSTABLE OVER SRN IND INTO SRN OH WITH 100 MB
   MLCAPE RANGING FROM 1000-1500 J/KG...WITH STORMS DEVELOPING ALONG
   AND JUST NORTH OF THE BOUNDARY DURING THE LAST HOUR.  DESPITE WEAK
   LOW-LEVEL FLOW...CONVERGENCE ALONG THE BOUNDARY WILL ALLOW FOR
   ADDITIONAL STORMS TO DEVELOP THIS AFTERNOON PRIMARILY OVER SRN OH
   INTO NRN KY.  MARGINAL DEEP LAYER SHEAR ASSOCIATED WITH 25 KT OF
   WSWLY 500 MB FLOW AT ILN VAD AND FURTHER AIR MASS DESTABILIZATION
   WILL SUPPORT MULTI-CELL STORMS PRODUCING HAIL/DAMAGING WINDS WITH
   THE STRONGEST ACTIVITY.
