AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA

SYNOPSIS
01/156 AM.
WARMER TEMPERATURES ARE EXPECTED TODAY AS OFFSHORE FLOW RETURNS
WITH AREAS OF GUSTY SANTA ANA WINDS. A COOLING TREND WILL DEVELOP
TUESDAY AND WEDNESDAY BEFORE SANTA ANA WINDS RETURN THURSDAY WITH
WARMER TEMPERATURES INTO EARLY NEXT WEEK.
SHORT TERM (TDY-THU)
01/100 PM.
THE MODERATE SANTA ANA EVENT WAS WANING EARLY THIS AFTERNOON WITH
MOST PLACES WITHIN THE SANTA ANA WIND CORRIDOR LIKELY FALLING
BELOW WIND ADVISORY THRESHOLDS BY 3 PM, THE EXPIRATION TIME OF THE
WIND ADVISORY. THE BREAK IN THE WIND WILL BE QUITE SHORT LIVED AS
A SECOND MODERATE SANTA ANA EVENT IS LIKELY BY AROUND NOON
WEDNESDAY AND CONTINUING INTO EARLY THURSDAY. SLIGHTLY STRONGER
UPPER LEVEL SUPPORT WITH THIS EVENT MAY BRING A BIT MORE
WIDESPREAD 50 TO LOCALLY 60 MPH GUSTS ACROSS PRONE MOUNTAIN AND
FOOTHILL AREAS. ELSEWHERE, GUSTS OF 30 TO 50 MPH WILL BE COMMON,
POTENTIALLY EXTENDING INTO THE ANTELOPE VALLEY (WEDNESDAY).
WHERE AND WHEN WINDS DROP OFF THE DRY AIR MASS WILL SUPPORT SOME
OF THE COOLEST OVERNIGHT LOWS WE HAVE EXPERIENCED THIS SEASON
WITH LOWS IN THE 30S AND 40S COMMON ON COLDER NIGHTS WITH A
SMATTERING OF 20S FOR THE FAR INTERIOR AND AT HIGH ELEVATIONS.
FREEZE WARNINGS ARE IN PLACE FOR TONIGHT FOR THE ANTELOPE VALLEY
AND INTERIOR SAN LUIS OBISPO WITH A FROST ADVISORY IN PLACE FOR
THE CUYAMA VALLEY. IF YOU LIVE IN THESE AREAS, TAKE STEPS TO
PROTECT ANY VULNERABLE ANIMALS OR PLANTS. ADDITIONAL FROST/FREEZE
PRODUCTS WILL LIKELY BE NEEDED IN THE NEXT FEW DAYS, ESPECIALLY
THURSDAY AND FRIDAY MORNINGS, IN THE WAKE OF THE SECOND SANTA ANA
WIND EVENT.
NEAR TO BELOW NORMAL TEMPERATURES WILL CONTINUE THROUGH THURSDAY.
MOSTLY SUNNY SKIES WILL PREVAIL, OUTSIDE OF POSSIBLE PUSH OF LOW
CLOUDS AND FOG TO COASTAL AREAS TUESDAY NIGHT INTO WEDNESDAY
MORNING AHEAD OF THE SECOND SANTA ANA WIND EVENT.
LONG TERM (FRI-MON)
01/100 PM.
RAIN FREE CONDITIONS LOOK TO CONTINUE WELL INTO NEXT WEEK. THERE
IS A 50-60 PERCENT CHANCE OF A STRONG RIDGE BUILDING OVERHEAD INTO
EARLY NEXT WEEK WITH WEAK TO MODERATE SANTA ANA CONDITIONS AT
TIMES. IN THIS SCENARIO, WIDESPREAD HIGHS IN THE MID 70S TO MID
80S WOULD BE IN PLAY FOR COASTS AND COASTAL VALLEYS. IF THE RIDGE
IS WEAKER OR OFFSHORE FLOW DOES NOT MATERIALIZE (40-50 PERCENT
CHANCE), MORE SEASONABLY WARM TEMPERATURES (60S AND 70S) WOULD BE
COMMON.
