...DISCUSSION FROM PHXFWFPSR...



HIGH PRESSURE BUILDING INTO THE REGION WILL LEAD TO MUCH WARMER

TEMPERATURES AND CONTINUED LOW RHS INTO THE WEEKEND. HIGHS WILL

REACH WELL INTO THE 90S TODAY BEFORE TOPPING 100 DEGREES BY FRIDAY

OR SATURDAY. EXPECT MINRHS FROM 7-12% EACH DAY THROUGH AT LEAST THE

WEEKEND. WINDS WILL REMAIN RELATIVELY LIGHT FOR MUCH OF THE PERIOD,

BUT SOME AFTERNOON BREEZINESS WITH GUSTS TO AROUND 20 MPH IS LIKELY.

THE COMBINATION OF THE VERY LOW RHS AND BREEZY CONDITIONS LIKELY

FOCUSED DURING THE LATE AFTERNOON HOURS ON  FRIDAY AND SATURDAY MAY

RESULT IN ELEVATED FIRE WEATHER  CONDITIONS FOR PORTIONS OF THE

AREA.



NOTE...ADDITIONAL FIRE WEATHER FORECAST INFORMATION  CAN BE FOUND IN

THE AREA FORECAST DISCUSSION. SEE PRODUCT PHXAFDPSR.
