...DISCUSSION FROM PHXFWFPSR...


WIND SPEEDS WILL INCREASE SUBSTANTIALLY BEGINNING THIS AFTERNOON
WITH GUSTS 25-35 MPH BECOMING COMMON. FOR THE EASTERN DISTRICTS INTO
PORTIONS OF SOUTHWEST ARIZONA, THE COMBINATION OF THE GUSTY WINDS
AND HUMIDITY VALUES FALLING INTO A 10-15% RANGE WILL YIELD  AN
ELEVATED FIRE DANGER. WHILE WIND SPEEDS WILL ONLY BE SLIGHTLY
WEAKER SUNDAY, HUMIDITY VALUES ONLY FALLING INTO A 20-25% RANGE
WILL PRECLUDE A GREATER THREAT. CORRESPONDINGLY, POOR TO FAIR
OVERNIGHT RECOVERY OF 20-50% WILL IMPROVE CLOSER TO A 40-60% RANGE
SUNDAY.

NOTE...ADDITIONAL FIRE WEATHER FORECAST INFORMATION CAN BE FOUND IN
THE AREA FORECAST DISCUSSION. SEE PRODUCT PHXAFDPSR.
