   NWS STORM PREDICTION CENTER NORMAN OK
   0217 AM CDT THU AUG 28 2008
   
   VALID 301200Z - 311200Z
   
   ...NO SVR TSTM AREAS FORECAST...
   
   AN UPPER-LEVEL RIDGE OVER THE HIGH PLAINS FRIDAY NIGHT IS FORECAST
   TO AMPLIFY AND MOVE INTO THE UPPER MIDWEST SATURDAY. AS SOUTHWEST
   FLOW DEVELOPS ACROSS THE NWRN STATES...A BROAD AND WELL-DEVELOPED
   LOW-LEVEL JET IS FORECAST TO DEVELOP OVER THE PLAINS. THIS WILL
   ALLOW MOISTURE TO QUICKLY SURGE NWD INTO THE CNTRL AND NRN PLAINS
   SATURDAY AND SATURDAY NIGHT. DESPITE THE INCREASE IN
   MOISTURE...LARGE-SCALE ASCENT IN THE NRN PLAINS SHOULD BE WEAK
   BEHIND THE EXITING RIDGE LIMITING CONVECTIVE DEVELOPMENT ALONG THE
   MOIST AXIS. THE GREATEST POTENTIAL FOR CONVECTIVE DEVELOPMENT
   APPEARS TO BE OVER THE CNTRL PLAINS AND OZARKS WHERE VERTICAL SHEAR
   IS EXPECTED TO QUITE WEAK.
