   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   UPPER FLOW PATTERN WILL BECOME LESS AMPLIFIED/MORE PROGRESSIVE AS
   STRONG BELT OF WLY/S IS CONFINED TO NRN TIER OF STATES.  A COLD
   FRONT WILL BE DRAPED NE TO SW FROM THE UPPER GREAT LAKES TO THE

   ...PARTS OF SWRN AND W-CNTRL INTERIOR FL PENINSULA...
   WITH LITTLE OVERALL CHANGE EXPECTED IN LARGER-SCALE FEATURES ACROSS
   THE SERN QUARTER OF THE CONUS...A CONTINUATION OF LOW RH/MODEST
   ELY/S WILL LIKELY OCCUR DURING PEAK HEATING.  FORECAST SOUNDINGS
   SHOW MIN RH FALLING AS LOW AS THE UPPER 20S WITH VALUES AOA 30
   PERCENT MORE WIDESPREAD.  BOUNDARY LAYER MEAN FLOW WILL REMAIN
   MODEST /BELOW 15 MPH/ AND THIS WILL TEND TO LIMIT THE DURATION OF
   MODERATE SUSTAINED WINDS /APPROACHING 15 MPH/ BUT GUSTS AROUND 20
   MPH ARE POSSIBLE.
