   AREAS AFFECTED...CNTRL/SRN LWR MI
   
   CONCERNING...SEVERE THUNDERSTORM POTENTIAL 
   
   VALID 060738Z - 060915Z
   
   PRESSURE FALLS HAVE BEEN INCREASING ACROSS LWR MI SINCE 04Z AS
   UPSTREAM POTENT SHORTWAVE TROUGH MIGRATES NEWD ACROSS THE MIDWEST. 
   AS A RESULT...WARM/MOIST BOUNDARY LAYER HAS SURGED N INTO CNTRL LWR
   MI WITH SURFACE TEMPERATURES IN THE MID-60S AND DEW POINTS IN THE
   MID-50S.  NRN PORTION OF THE SQUALL LINE ACROSS SWRN LWR MI HAS
   SHOWN SIGNS OF INTENSIFYING PER COOLING CLOUD TOPS IN IR SATL.
   
   AS THE UPSTREAM IMPULSE ROTATES NEWD AND ASSOCIATED SFC LOW DEEPENS
   RAPIDLY ACROSS LWR MI...TSTMS SHOULD BE MAINTAINED OR COULD INCREASE
   AS THEY MOVE NEWD ACROSS CNTRL/SRN LWR MI.  GIVEN THE STRONG
   LOW/MID-LEVEL WIND FIELDS AND DESTABILIZING BOUNDARY LAYER...THESE
   TSTMS MAY TEND TO BOW AND PRODUCE DAMAGING WINDS.  
   
   A SEVERE TSTM WATCH MAY BE NEEDED SHORTLY.
