STRENGTHENING HIGH PRESSURE ALOFT WILL BRING A WARMING TREND WITH A
LONG-DURATION HEAT WAVE LIKELY FOR THIS WEEKEND THROUGH MUCH OF NEXT
WEEK INTO THE FOLLOWING WEEKEND. EASTERLY FLOW ALOFT WILL CREATE
WEAK SANTA ANA WINDS ALONG WEST-FACING MOUNTAIN SLOPES, ADJACENT
FOOTHILLS, AND LOCALLY INTO VALLEYS FRIDAY THROUGH SUNDAY. WINDS
WILL PEAK ON SATURDAY WITH GUSTS 25-45 MPH, LOCALLY HIGHER ALONG
WIND-PRONE MOUNTAIN SLOPES. THIS WILL COMBINE WITH HEAT, DRY FUELS,
AND RH VALUES 15-25% TO PRODUCE ELEVATED FIRE WEATHER CONDITIONS FOR
MOUNTAINS AND INLAND VALLEYS. WINDS ARE EXPECTED TO DIMINISH AFTER
SUNDAY. THERE COULD BE ADDITIONAL PERIODS OF MOSTLY WEAK OFFSHORE
FLOW NEXT WEEK, BUT WITH LOWER CONFIDENCE IN THE TIMING AND OTHER
DETAILS.

..DISCUSSION FROM PHXFWFPSR
GRADUAL DRYING AS HIGH PRESSURE TAKES HOLD OVER THE REGION WILL LEAD
TO SOMEWHAT LOWER HUMIDITIES AND MOSTLY CLEAR SKIES THROUGH THE
REST OF THE WEEK. NEAR NORMAL TEMPERATURES ARE EXPECTED WITH THE
WARMEST TEMPERATURES CONSISTENTLY ACROSS THE WESTERN DISTRICTS.
MINRHS WILL MOSTLY RANGE FROM 15-25% OVER THE WESTERN DISTRICTS TO
25-35% FOR THE EASTERN DISTRICTS WITH GOOD TO EXCELLENT OVERNIGHT
RECOVERIES. AFTER LIGHT WINDS TODAY, BREEZY EAST WINDS WILL SET UP
TONIGHT INTO FRIDAY AND PERSIST FOR SEVERAL DAYS. MORNING WIND GUSTS
OF 20-30 MPH WILL BE COMMON STARTING FRIDAY.
NOTE...ADDITIONAL FIRE WEATHER FORECAST INFORMATION CAN BE FOUND IN
THE AREA FORECAST DISCUSSION. SEE PRODUCT PHXAFDPSR.
