..DISCUSSION FROM PHXFWFPSR
ELEVATED FIRE DANGER WILL CONTINUE TODAY DUE TO LOW HUMIDITY, VERY
WARM TEMPERATURES, AND AFTERNOON UPSLOPE/UPVALLEY BREEZY CONDITIONS
WITH CRITICAL CONDITIONS DEVELOPING FRIDAY. MINRHS TODAY WILL FALL
INTO THE SINGLE DIGITS ACROSS THE WESTERN DISTRICTS, BUT CLOSER TO
20% IN THE EAST. THESE VALUES WILL FALL CLOSER TO 5-15% STARTING
FRIDAY. WINDS WILL GENERALLY REMAIN TERRAIN DRIVEN TODAY WITH
UPSLOPE GUSTS DURING THE LATTER HALF OF THE AFTERNOON PEAKING AROUND
25 MPH. GUSTS ARE EXPECTED TO INCREASE INTO A 20-35 MPH RANGE
FRIDAY WITH A RISK OF EXTREME FIRE BEHAVIOR.
