   HUMIDITIES WILL LINGER THROUGH THE DAY ACROSS SRN CA...THOUGH WITH
   LIGHT WINDS.
   
   ...SRN CA...
   WV IMAGERY/SURFACE ANALYSIS REFLECTS THAT A DRY AIRMASS IS LINGERING
   ACROSS SRN CA...AND LITTLE RELATIVE HUMIDITY RECOVERY IS OCCURRING.
   ALTHOUGH THE PRESSURE GRADIENT HAS WEAKENED AND WINDS REMAIN
   LIGHT...THE DRY AIRMASS WILL LEAD TO ANOTHER DAY OF CRITICALLY LOW
   RELATIVE HUMIDITIES AS DIURNAL HEATING OCCURS. ISOLATED LOCALLY
   GUSTY WINDS JUXTAPOSED WITH SINGLE DIGIT RELATIVE HUMIDITIES MAY BE
   POSSIBLE BY AFTERNOON. ONSHORE FLOW WILL GRADUALLY BEGIN TO
   STRENGTHEN OVERNIGHT...LEADING TO A SLOW RELATIVE HUMIDITY RECOVERY.
