   NWS STORM PREDICTION CENTER NORMAN OK

   AREAS AFFECTED...ERN KY...EXTREME SRN KY THROUGH SRN WV
   
   CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 
   
   VALID 121416Z - 121615Z
   
   THREAT FOR ISOLATED DAMAGING WIND AND HAIL EXPECTED TO INCREASE
   THROUGH THE MORNING INTO THE AFTERNOON. TRENDS ARE BEING MONITORED
   FOR A POSSIBLE WW.
   
   QUASI-STATIONARY FRONT EXTENDS FROM NRN WV THROUGH SRN OH...SRN IND
   AND IL. AN MCS CONTINUES FROM SRN IND...NRN KY AND SRN OH. BOUNDARY
   LAYER WILL UNDERGO DESTABILIZATION THROUGH THE MORNING...BUT WILL BE
   MITIGATED SOMEWHAT BY EXTENSIVE CONVECTIVE DEBRIS. THE LATEST
   OBJECTIVE ANALYSIS SHOWS A RESERVOIR OF 1000 MLCAPE IN WARM SECTOR.
   A 40 KT WSWLY LOW-LEVEL JET WILL MIGRATE EWD THROUGH NRN KY IN
   ASSOCIATION WITH A PROGRESSIVE MCV LOCATED OVER ERN IL. THE
   LOW-LEVEL JET WILL MAINTAIN FEED OF HIGHER THETA-E AIR INTO THE
   MCS...AND STORMS WILL LIKELY INTENSIFY AS THE ATMOSPHERE
   DESTABILIZES. UNIDIRECTIONAL 40-45 KT DEEP SHEAR WILL SUPPORT
   POTENTIAL FOR ORGANIZED STORMS. GREATEST THREAT FOR DAMAGING WIND
   WILL LIKELY BE WITH NE-SW ORIENTED LINE OF STORMS ALONG THE WRN END
   OF THE MCS. ACTIVITY COULD BUILD A LITTLE FARTHER SWD AS MCS
   CONTINUES EWD. VERY HEAVY RAIN AND POSSIBLY SOME HAIL WILL REMAIN
   LIKELY WITH E-W BAND OF STORMS DEVELOPING ON THE WARM ADVECTION
   WING.
