NWS STORM PREDICTION CENTER NORMAN OK
0755 PM CDT TUE SEP 08 2009
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.
