   DAY 1 CONVECTIVE OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK

   VALID 090100Z - 091200Z
   
   ...THERE IS A SLGT RISK OF SVR TSTMS FROM ERN ND SSWWD INTO THE
   CENTRAL HIGH PLAINS...
   
   ...SERN SD SSWWD INTO PARTS OF ERN CO/WRN KS...
   A BROKEN LINE OF THUNDERSTORMS IS ONGOING ATTM INVOF THE COLD FRONT
   PROGRESSING SLOWLY EWD ACROSS THE PLAINS.  COMBINATION OF AMPLE
   INSTABILITY AND AN INCREASING LOW-LEVEL JET SHOULD ALLOW STORMS TO
   CONTINUE OVER THE NEXT SEVERAL HOURS...THOUGH SLOW DIURNAL
   STABILIZATION OF THE LOWER TROPOSPHERE SHOULD RESULT IN AN OVERALL
   DECREASE IN CONVECTIVE INTENSITY WITH TIME.
   
   IN THE MEAN TIME...MODEST SHEAR WILL CONTINUE TO SUPPORT ISOLATED
   STRONGER STORMS...WITH THE HAIL/WIND POTENTIAL LIKELY TO PERSIST
   THROUGH MUCH OF THE EVENING.
