..DISCUSSION FROM RNOFWFVEF
HIGH PRESSURE MAINTAINS WARM AND DRY CONDITIONS OVER THE NEXT
7 DAYS. MINIMUM HUMIDITY WILL BE BETWEEN 15 AND 30 PERCENT SOUTH
AND EAST OF INTERSTATE 15, AND BETWEEN 10 AND 20 PERCENT WEST AND
NORTH OF INTERSTATE 15. WINDS REMAIN FAIRLY LIGHT AND FOLLOW
TYPICAL DAILY DIRECTIONAL PATTERNS ON MOST DAYS. A WEAK DISTURBANCE
MAY BRIG A SLIGHT INCREASE IN SOUTHEASTERLY WINDS TO SOUTHERN NEVADA
AND SOUTHEASTERN CALIFORNIA ON SUNDAY, MAINLY OVER HIGH TERRAIN.
..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
DRIER CONDITIONS ARE EXPECTED TO LAST THROUGH THE WEEKEND, WITH
PERSISTENT CLEAR SKIES AS A HIGH PRESSURE SYSTEM SETS UP OVER THE
REGION. 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.
