...DISCUSSION FROM PHXFWFPSR...



NEAR TO SLIGHTLY ABOVE NORMAL TEMPERATURES WILL PERSIST THROUGH THE

END OF THE WEEK. OVERALL WINDS WILL BE FAIRLY LIGHT AND  DIURNAL,

WITH SOME AFTERNOON UPSLOPE GUSTINESS. MIN RHS WILL RANGE BETWEEN

10-15% THROUGH THE END OF THE WEEK ACROSS MOST PLACES. A FAIRLY

POTENT WEATHER SYSTEM WILL THEN MOVE ACROSS THE REGION  DURING THE

UPCOMING WEEKEND DELIVERING ENHANCED WINDS AS WELL AS  MUCH COOLER

TEMPERATURES. MINRHS WILL RANGE BETWEEN 15-20% ACROSS  MOST AREAS ON

SATURDAY BEFORE INCREASING TO ABOVE 20% BY SUNDAY. SOME ELEVATED

FIRE WEATHER CONCERNS ARE ANTICIPATED OVER THE WEEKEND AS A RESULT

OF THE STRENGTHENING WINDS. 



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

THE AREA FORECAST DISCUSSION. SEE PRODUCT PHXAFDPSR.
