   CORRECTED FOR GEOGRAPHICAL DESCRIPTOR
   
   THE POTENTIAL FOR LOCALLY DAMAGING WIND GUSTS WILL EXIST WITH
   EVOLVING MCS AS IT BEGINS TO MOVE/DEVELOP E OF WW 668 BETWEEN
   04-05Z.  AN ADDITIONAL WW IS NOT ANTICIPATED ATTM.
   
   LOW-LEVEL FRONTAL SURGE IS IN THE PROCESS OF OVERTAKING WRN EDGE OF
   TSTMS WHICH HAVE PERSISTED OVER NERN KS THIS EVENING WITH CONVECTIVE
   SYSTEM EXPECTED TO BECOME MORE PROGRESSIVE OVER THE NEXT 1-2 HOURS. 
   AMBIENT INFLOW AIR MASS REMAINS QUITE MOIST AND RELATIVELY WARM THIS
   EVENING...HOWEVER MODIFICATION OF 00Z TOP SOUNDING FOR CURRENT
   SURFACE CONDITIONS SUGGEST THAT CAP IS GRADUALLY INCREASING.
   
   LARGE-SCALE FORCING ATTENDANT TO SHORT WAVE TROUGH TRANSLATING EWD
   THROUGH SD/NEB COUPLED WITH GROWING/DEEPENING MCS COLD POOL SHOULD
   AID IN IT/S MAINTENANCE AS IT PROGRESSES EWD ACROSS PORTIONS OF SRN
   IA AND NWRN MO OVERNIGHT.  LOCALLY DAMAGING WIND GUSTS WILL REMAIN
   THE PRIMARY SEVERE WEATHER HAZARD WITH THIS SYSTEM...THOUGH THE
   WEAKENING LOW-LEVEL LAPSE RATES AND INCREASING CAP MAY TEND TO LIMIT
   A MORE ORGANIZED SEVERE WEATHER THREAT.
