   AREAS AFFECTED...WRN IL/NERN TO SWRN MO/SERN KS/NERN OK
   
   CONCERNING...SEVERE THUNDERSTORM WATCH 348...349...
   
   VALID 080825Z - 080930Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
   348...349...CONTINUES.
   
   ISOLATED SEVERE HAIL IS POSSIBLE WITHIN VALID PORTIONS OF WW/S 348
   AND 349.
   
   ALTHOUGH REGIONAL RADARS HAVE INDICATED AN OVERALL DIMINISHING TREND
   WITH STORM INTENSITIES ACROSS WW/S 348 AND 349...FORCING FOR ASCENT
   AHEAD OF SHORT WAVE TROUGH...CURRENTLY PROGRESSING EWD ACROSS THE
   CENTRAL PLAINS...WILL SUPPORT TSTMS SPREADING EWD OVERNIGHT.  THIS
   ASCENT IS EVIDENT IN LATEST COOLING CLOUD TOPS ACROSS NERN OK/SERN
   KS AND NWRN MO.  IN ADDITION...LOW LEVEL WAA ACROSS NERN OK/SERN KS
   AND FROM THE MID MS VALLEY TO ERN IA/NRN IL/SRN WI WILL SUPPORT THIS
   OVERNIGHT/EARLY MORNING TSTM ACTIVITY.
   
   DESPITE THE LIKELIHOOD FOR TSTMS TO PERSIST FROM NERN OK/SERN KS
   THROUGH THE LOWER MO VALLEY TO WRN/NRN IL...RECENT TRENDS IN
   OBJECTIVE ANALYSES SUGGEST DECREASING INSTABILITY AND INCREASING
   INHIBITION.  THIS SHOULD TEND TO LIMIT A WIDESPREAD SEVERE
   THREAT...BUT STRONG FORCING FOR ASCENT WILL SUPPORT AN ISOLATED
   SEVERE THREAT WITH ANY PERSISTENT UPDRAFTS.
