..DISCUSSION FROM RNOFWFVEF
WARMER THAN NORMAL TEMPERATURES AND DRY CONDITIONS WILL CONTINUE FOR
ONE MORE DAY. BREEZY SOUTHERLY WINDS WILL PICK UP IN THE OWENS
VALLEY AND ACROSS THE SOUTHERN GREAT BASIN THIS AFTERNOON. A PATTERN
CHANGE WILL BRING GUSTY SOUTHWESTERLY WINDS TO THE REGION ON
TUESDAY, WITH WINDS LINGERING ACROSS THE MOJAVE DESERT INTO
NORTHWESTERN ARIZONA ON WEDNESDAY. INCREASED PRECIPITATION CHANCES
WILL ACCOMPANY THIS PATTERN CHANGE FOR THE MOUNTAINS OF INYO COUNTY
AND THE HIGHER TERRAIN OF THE SOUTHERN GREAT BASIN. TEMPERATURES
WILL COOL, DROPPING BELOW NORMAL ON WEDNESDAY BEFORE REBOUNDING
DURING THE SECOND HALF OF THE WEEK.
..DISCUSSION FROM LAXFWFSGX
ONSHORE FLOW WILL BEGIN TO STRENGTHEN TODAY WITH HIGH TEMPERATURES
FOR THE COAST AND VALLEYS COOLING A FEW DEGREES. A LOW PRESSURE
SYSTEM MOVING INLAND THROUGH CALIFORNIA WILL BRING MORE COOLING FOR
TUESDAY AND WEDNESDAY AND SPREAD HIGHER COASTAL HUMIDITY INLAND
WITH SOUTHWEST TO WEST WINDS FOR THE MOUNTAINS AND DESERTS
STRONGEST FOR TUESDAY AFTERNOON AND NIGHT WITH GUSTS TO 40 TO 50
MPH AND ISOLATED GUSTS TO 65 MPH. THERE IS ALSO A SLIGHT CHANCE FOR
LIGHT SHOWERS FOR LATE TUESDAY AFTERNOON THROUGH TUESDAY NIGHT WITH
THE CHANCE FOR WETTING PRECIPITATION FOR THE SAN BERNARDINO COUNTY
MOUNTAINS 15 TO 25 PERCENT, AND LESS THAN 10 PERCENT ELSEWHERE.
THURSDAY WILL BE WARMER FOLLOWED BY A COOLING TREND THROUGH NEXT
WEEKEND.
..DISCUSSION FROM PHXFWFPSR
A VERY PROGRESSIVE PATTERN WITH MULTIPLE DRY WEATHER SYSTEMS
PASSING NORTH OF THE REGION WILL RESULT IN BREEZY CONDITIONS AND
PERIODS OF ELEVATED FIRE WEATHER THROUGHOUT THIS WEEK. DURING THE
FIRST HALF OF THE WEEK, ABOVE NORMAL TEMPERATURES AND BREEZY
CONDITIONS COMBINED WITH MIN RH VALUES OF 8-15% WILL RESULT IN
WIDESPREAD ELEVATED FIRE WEATHER CONDITIONS, ESPECIALLY ACROSS THE
WESTERN DISTRICTS ON TUESDAY AND THE HIGHER TERRAIN OF SOUTH
CENTRAL AZ ON WEDNESDAY WHERE GUSTS UP 20-30 MPH WILL BE COMMON.
BREEZY AND DRY CONDITIONS WILL CARRY THROUGH THE REST OF THIS WEEK
AND INTO THIS WEEKEND WITH RELATIVE HUMIDITY REMAINING AT OR
BELOW 15% EACH AFTERNOON. OVERNIGHT RECOVERIES WILL ALSO VARY
THROUGH THE WEEK, BUT REMAIN MOSTLY IN THE 30-50% RANGE.
