AFTER SUNSET WITH RH VALUES RECOVERING BETTER THAN OF LATE BEHIND THE
FRONT. CONDITIONS WILL BE QUIET OVERALL ON SUNDAY WITH GENERALLY
LIGHT WINDS. TEMPERATURES WILL BE FAIRLY COOL BUT WILL BEGIN TO
REBOUND MONDAY. SKY CONDITIONS THROUGH THE PERIOD MAY HAVE SOME
VARIABILITY AS SMOKE FROM FIRES FURTHER WEST CAUSE OBSCURATION.
