ARIZONA AND SOUTHEAST CALIFORNIA
NATIONAL WEATHER SERVICE PHOENIX AZ
131 PM MST FRI MAR 6 2026
DISCUSSION
FLUCTUATING TEMPERATURES WITH BREEZY TO LOCALLY WINDY CONDITIONS
CAN BE EXPECTED THROUGH THE END OF THE WORKWEEK/START OF THE
WEEKEND. MINRH VALUES WILL HOVER CLOSE TO 10-15% THE NEXT FEW
AFTERNOONS WITH POOR TO MODEST OVERNIGHT RECOVERY. BREEZY TO WINDY
CONDITIONS, WITH GUSTS 25-35 MPH, LOCALLY HIGHER IN SOME SPOTS,
WILL EXITS THROUGH SATURDAY, MAINLY FOR THE WESTERN DISTRICTS.
THE COMBINATION OF LOW RH AND ELEVATED WINDS WILL CREATE INSTANCES
OF ELEVATED TO NEAR CRITICAL FIRE WEATHER CONDITIONS. HOWEVER,
FUEL MOISTURE'S REMAIN RELATIVELY HIGH AND SHOULD LIMIT
SIGNIFICANT FIRE POTENTIAL. TEMPERATURES WILL COOL TO NEAR AND
EVEN BELOW NORMAL BY TODAY BEFORE QUICKLY INCREASING AGAIN FOR THE
WEEKEND.
NOTE...ADDITIONAL FIRE WEATHER FORECAST INFORMATION CAN BE FOUND
IN THE AREA FORECAST DISCUSSION. SEE PRODUCT PHXAFDPSR.
