MESOSCALE DISCUSSION 1284
   NWS STORM PREDICTION CENTER NORMAN OK
   0900 PM CDT MON JUN 09 2003
   
   AREAS AFFECTED...CENTRAL KS / WRN OK / EXTREME ERN TX PANHANDLE
   
   CONCERNING...SEVERE THUNDERSTORM POTENTIAL 
   
   VALID 100200Z - 100300Z
   
   A WW MAY BECOME NECESSARY FOR MUCH OF CENTRAL KS INTO WRN OK.  LARGE
   HAIL WOULD BE THE MOST LIKELY SEVERE THREAT...WITH ISOLATED
   TORNADOES POSSIBLE AS WELL.
   
   CLUSTER OF SEVERE THUNDERSTORMS HAS FORMED ON A NWD MOVING OUTFLOW
   BOUNDARY FROM CONVECTION FURTHER SOUTH.  THIS INDICATES RELATIVELY
   SMALL AMOUNTS OF CIN ARE PRESENT.  ADDING MOISTURE REPRESENTATIVE OF
   MOIST AXIS TO 00Z DDC RAOB SUPPORTS THIS ASSERTION.  GIVEN VERY
   STRONG INSTABILITY AND INCREASING SSWLY LLJ...CONDITIONS WILL REMAIN
   FAVORABLE FOR FURTHER DEVELOPMENT.  LARGE HAIL AND ISOLATED
   TORNADOES WILL BE POSSIBLE.  LARGE LOOP HODOGRAPHS WITH WEAK DEEP
   LAYER SHEAR WILL MAKE FOR SLOW MOVING STORMS.  TORNADOES WOULD
   LIKELY BE BRIEF.
