WITH TEMPERATURES COOLING SLIGHTLY, BUT STILL SOMEWHAT ABOVE NORMAL, VERY DRY CONDITIONS WILL PERSIST THROUGH SATURDAY. MINIMUM HUMIDITY VALUES WILL MOSTLY FALL IN A 5-10% RANGE FOLLOWING GENERALLY POOR OVERNIGHT RECOVERY OF 20-30%. WIND GUSTS 20-30 MPH SHOULD DEVELOP OVER MUCH OF THE REGION WITH THE STRONGEST GUSTS NEAR AND DOWNSTREAM OF RIDGE TOPS YIELDING AN ELEVATED FIRE DANGER. GUSTS SHOULD BE WEAKER SATURDAY REDUCING THE FIRE WEATHER THREAT. NOTE...ADDITIONAL FIRE WEATHER FORECAST INFORMATION CAN BE FOUND IN THE AREA FORECAST DISCUSSION. SEE PRODUCT PHXAFDPSR. $$
