..DISCUSSION FROM RNOFWFVEF
THE BUILDING HIGH PRESSURE PATTERN LASTS THROUGH THE FORECAST PERIOD
RESULTING IN CONTINUED CALM AND DRY WEATHER. DAYTIME MINIMUM
HUMIDITIES WILL RANGE FROM 10 TO 30 PERCENT FOR MOST AREAS, WITH THE
DRIER AREAS BEING NORTH OF INTERSTATE 15. OVERNIGHT HUMIDITY
RECOVERIES WILL BE UP TO 30 TO 45 PERCENT NORTH OF I-15 AND ABOVE
50 PERCENT FOR AREAS TO THE SOUTH AND EAST OF I-15. WINDS LOOK TO
REMAIN LIGHT THROUGH THE NEXT WEEK WITH ONLY SOME BRIEF PERIODS OF
BREEZY WINDS ON HIGHER TERRAIN EXPECTED. HUMIDITIES IMPROVE SLIGHTLY
INTO THE NEXT WORK WEEK, BUT NO SIGNIFICANT CHANGES IN WEATHER ARE
EXPECTED OVER THE NEXT 7 DAYS.
..DISCUSSION FROM LAXFWFSGX
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
DRY CONDITIONS WITH NEAR NORMAL TEMPERATURES ARE ANTICIPATED
THROUGH THIS WEEKEND. MINRHS WILL MOSTLY RANGE FROM 15-25% OVER THE
WESTERN DISTRICTS TO 25-35% FOR THE EASTERN DISTRICTS WITH GOOD TO
EXCELLENT OVERNIGHT RECOVERIES. A PERSISTENT BREEZY EASTERLY
GRADIENT WIND WILL DEVELOP ACROSS THE REGION TODAY AND PERSIST FOR
THE NEXT SEVERAL DAYS. MORNING TO EARLY AFTERNOON WIND GUSTS OF
20-30 MPH WILL BECOME COMMON.
