   OVERNIGHT RH RECOVERIES...CRITICAL CONDITIONS ARE NOT ANTICIPATED.
   
   ...SOUTHEAST STATES/NORTHERN FL...
   GRADUAL APPROACH OF HIGH PRESSURE AND WEST-NORTHWESTLY CONTINENTAL

   ...CRITICAL FIRE WEATHER AREA FOR COASTAL AREAS OF SOUTHERN CA...
   
   ...SYNOPSIS...
   WITHIN THE LONGWAVE TROUGH OVER THE EASTERN TWO-THIRDS OF THE

   CONDITIONS...CONSIDERABLE LONGER TERM PRECIPITATION DEFICIENCIES
   EXIST ACROSS SOUTHERN CA.

   AS SURFACE HIGH PRESSURE APPROACHES...A DRY AIRMASS WILL CONTINUE TO
   DEVELOP ACROSS MUCH OF THE SOUTHEAST STATES AND FL. EVEN WITH
   RELATIVELY COOL TEMPERATURES IN THE 40S AND 50S AND RECENT
   PRECIPITATION...DRYING NATURE OF THE AIRMASS WILL LEAD TO CRITICAL

   NORTHERN FL FRIDAY AFTERNOON...RANGING TO AROUND 35 PERCENT ACROSS
