   AN ISOLATED SEVERE THREAT WILL CONTINUE ACROSS THE OH VALLEY THROUGH
   EARLY TO MID-EVENING. HAIL AND WIND DAMAGE SHOULD BE THE PRIMARY
   THREAT ALTHOUGH A TORNADO CAN NOT BE RULED OUT. WW ISSUANCE REMAINS
   POSSIBLE ACROSS THE REGION.
   
   ISOLATED THUNDERSTORM DEVELOPMENT IS OCCURRING IN ERN IL ALONG AN
   AXIS OF MODERATE INSTABILITY. THE SEVERE STORM IN NE IL IS LOCATED
   ALONG A WELL-DEFINED BOUNDARY WHICH MAY BE LOCALLY ENHANCING SHEAR
   PROFILES ENABLING THE STORM TO BE ORGANIZED. IF THE STORM CAN
   PERSIST...THEN THE THREAT FOR HAIL AND WIND DAMAGE WOULD MOVE INTO
   CNTRL IND ALONG THE NRN EDGE OF A GRADIENT OF MODERATE INSTABILITY.
   FURTHER TO THE SOUTH ACROSS THE WARM SECTOR...THUNDERSTORMS ARE
   DEVELOPING IN SRN IL. THIS ACTIVITY IS LOCATED IN A WEAKLY SHEARED
   ENVIRONMENT SUGGESTING ANY SEVERE THREAT WILL BE BRIEF. DUE TO STEEP
   LOW-LEVEL LAPSE RATES...A WIND DAMAGE THREAT COULD EXIST AS THE
   STORMS MATURE AND GUST OUT.
