MESOSCALE DISCUSSION 0828
   NWS STORM PREDICTION CENTER NORMAN OK
   0527 PM CDT THU MAY 08 2008
   
   AREAS AFFECTED...SRN IND/FAR NWRN-NORTH CENTAL KY/SWRN TO CENTRAL OH
   
   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 
   
   VALID 082227Z - 082330Z
   
   ISOLATED BRIEF TORNADO THREAT SHOULD PERSIST INTO THE EARLY EVENING
   ACROSS SWRN INTO PARTS OF CENTRAL OH...WITH A SIMILAR THREAT
   POSSIBLE SWWD THROUGH SRN IND AND PARTS OF NWRN TO NORTH CENTRAL KY.
   
   SURFACE ANALYSIS INDICATED AN AREA OF LOW PRESSURE OVER FAR SERN
   IL...WITH A WARM FRONT EXTENDING ENEWD THROUGH SRN IND TO CENTRAL OH
   AND SWRN PA.  INSTABILITY AND DEEP LAYER SHEAR ARE QUITE WEAK ACROSS
   THE OH VALLEY.  HOWEVER...FORCING FOR ASCENT ATTENDANT TO A MID
   LEVEL CIRCULATION CENTER MOVING NEWD THROUGH SWRN INTO CENTRAL OH
   AND A SECOND CIRCULATION CENTER CURRENTLY LOCATED OVER SRN IL SHOULD
   SUPPORT ADDITIONAL DEVELOPMENT INTO THE EARLY EVENING FROM SRN
   IND/FAR NWRN KY TO OH.  ILN WSR-88D VWP INDICATED GENERALLY WEAK
   WINDS /20 KTS OR LESS/ IN THE LOW LEVELS...BUT WINDS DID VEER WITH
   HEIGHT...SUGGESTING A POTENTIAL FOR LOW LEVEL ROTATION.  MESOSCALE
   ANALYSIS ALSO SHOWED SURFACE VORTICITY ALONG THE WARM FRONT AND LOW
   LEVEL CAPE AXIS ALONG AND JUST S OF THE WARM FRONT.  THIS SUGGESTS A
   SOMEWHAT ENHANCED BRIEF TORNADO POTENTIAL WITH STORMS THAT DEVELOP
   PRIOR TO BOUNDARY LAYER COOLING/STABILIZATION.
