..DISCUSSION FROM MONTEREY
BENIGN CONDITIONS CONTINUE INTO THE WEEKEND WITH A COOLING TREND
EXTENDING THROUGH NEXT WEEK. BREEZY ONSHORE WINDS DEVELOP EACH
AFTERNOON AND EVENING, MAINLY NEAR FAVORED GAPS AND PASSES.
HUMIDITIES INCREASE THROUGH THE FORECAST PERIOD, WITH A POTENTIAL
PATTERN CHANGE EARLY NEXT WEEK THAT COULD BRING EVEN DEEPER MOISTURE
TO THE DISTRICT.
NOTE : ALL WINDS ARE 20-FOOT WINDS UNLESS OTHERWISE SPECIFIED.
THUNDERSTORMS IMPLY STRONG, GUSTY AND ERRATIC WINDS.
..DISCUSSION FROM LOS ANGELES/OXNARD
THE MONSOONAL MOISTURE AND INSTABILITY CONTINUES TO DIMINISH ACROSS
OUR MOUNTAINS AND DESERTS, WITH THE THUNDERSTORM PROBABILITY ONLY
5 TO 15 PERCENT ACROSS THE EASTERN SAN GABRIEL MOUNTAINS, EASTERN
ANTELOPE VALLEY, AND NORTHERN VENTURA COUNTY MOUNTAINS. IF ANY
STORMS WERE TO DEVELOP, THE MAIN THREATS WOULD BE ISOLATED DRY
LIGHTNING STRIKES AND GUSTY WINDS AS MOISTURE REMAINS LIMITED. A
DRIER AIR MASS WILL MOVE INTO THE REGION ON FRIDAY AND CONTINUE
THROUGH THE WEEKEND.
AS THE UPPER LEVEL RIDGE OF HIGH PRESSURE CONTINUED TO WEAKEN AND
ONSHORE FLOW NEAR THE SURFACE GRADUALLY INCREASES, THERE WILL
CONTINUE TO BE A SLIGHT DOWNWARD TREND IN TEMPERATURES THE NEXT FEW
DAYS, BUT STILL VERY WARM ACROSS THE INTERIOR WITH TEMPERATURES WELL
INTO THE 90S. THE VERY WARM TEMPERATURES COMBINED WITH RESIDUAL
INSTABILITY WILL RESULT IN MODERATELY DEEP MIXING HEIGHTS BETWEEN
10,000 AND 13,000 FEET EACH AFTERNOON THROUGH SATURDAY. AS A RESULT,
THERE IS STILL AN ELEVATED RISK FOR LARGE PLUME DOMINATED FIRES
ACROSS THE INTERIOR.
WITH A DRYING AIR MASS, THE HUMIDITY LEVELS WILL TREND DOWN THE NEXT
FEW DAYS, WITH MINIMUMS BETWEEN 10 AND 20 PERCENT BECOMING COMMON BY
FRIDAY AND SATURDAY. TYPICAL DIURNAL WINDS ARE ANTICIPATED FOR THE
NEXT SEVERAL DAYS, EXCEPT FOR SUNDOWNER WINDS FOR SOUTHWESTERN SANTA
BARBARA COUNTY DURING THE EVENINGS (NORTHWEST 15 TO 25 MPH WITH GUST
TO 35 MPH).
