..DISCUSSION FROM PHXFWFPSR
TEMPERATURES WILL CONTINUE TO TREND TOWARDS SEASONAL NORMALS WHILE
DRIER AIR SURGES INTO THE REGION THROUGH FRIDAY. AS A RESULT,
MINIMUM AFTERNOON HUMIDITY VALUES 10-20% RANGE WILL FALL CLOSER TO
SINGLE DIGITS FRIDAY AFTERNOON. OVERNIGHT RECOVERY WILL ALSO RETREAT
INTO A POOR TO FAIR RANGE OF 20-45%. ENHANCED UPSLOPE AFTERNOON AND
EARLY EVENING BREEZINESS WILL BECOME COMMON RESULTING IN A
MODERATELY ELEVATED FIRE DANGER OVER MOST DISTRICTS.
