..DISCUSSION FROM PHXFWFPSR
TEMPERATURES WILL COOL SLIGHTLY THROUGH THURSDAY AS A DRIER AIRMASS
MOVES INTO THE REGION. AS A RESULT, MINIMUM AFTERNOON HUMIDITY
VALUES WILL FALL BELOW 10% IN WESTERN DISTRICTS AND 15-20% IN
EASTERN DISTRICTS. OVERNIGHT RECOVERY WILL ALSO RETREAT INTO A POOR
TO FAIR RANGE OF 20-50%. ENHANCED AFTERNOON AND EARLY EVENING
GUSTINESS WILL BECOME MORE COMMON WITH THE STRONGEST SPEEDS ACROSS
SOUTHEAST CALIFORNIA AND RIDGE TOPS OF SOUTH-CENTRAL ARIZONA. THIS
WILL RESULT IN LOCALIZED AREAS OF ELEVATED FIRE DANGER.
..THUNDERSTORMS IMPLY GUSTY WINDS
