SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
230 PM PST WED MAR 7 2012

.SYNOPSIS...

BUILDING HIGH PRESSURE ACROSS THE REGION WILL BRING A WARMING
TREND TO THE AREA THROUGH THE END OF THE WEEK. A SERIES OF WEAK
COLD FRONTS WILL DROP SOUTH INTO SOUTHWEST CALIFORNIA EARLY NEXT
WEEK...COMMENCING A GENERAL COOLING TREND INTO MIDWEEK NEXT WEEK.

&&

.SHORT TERM (TONIGHT-SATURDAY)...

ADDED A FROST ADVISORY FOR THE CENTRAL COAST...SANTA YNEZ VALLEY AND
THE VENTURA COUNTY INTERIOR VALLEYS...ESPECIALLY THE OJAI VALLEY
AREA FOR LATE TONIGHT. TEMPERATURES WILL DROP TO AROUND 30 DEGREES
IN THE COLDEST LOCATIONS FOR 2 TO 4 HOURS. AFTER TONIGHT...A RIDGE
OF HIGH PRESSURE BUILDS INTO SOUTHERN CALIFORNIA AND WEAK OFFSHORE
FLOW WILL COMBINE WITH THE RIDGE TO PRODUCE WARMER HIGH TEMPERATURES
THROUGH FRIDAY. THE WARMEST LOCATIONS WILL TOP OUT IN THE LOWER 80S.
NORTHEAST WINDS WILL OCCUR EACH MORNING THROUGH FRIDAY WITH GUSTS
AROUND 25 TO 30 MPH. SKIES WILL REMAIN CLEAR.

FOR SATURDAY...MADE A LAST SECOND DECISION TO INCREASE THE HIGH
TEMPERATURES FOR SATURDAY ACROSS THE INTERIOR SECTIONS. THE COASTAL
SECTIONS ARE STILL EXPECTED TO COOL DOWN AS THE OFFSHORE FLOW
TRANSITIONS TO ONSHORE FLOW LATE IN THE DAY. STILL EXPECTING SOME
KIND OF A MARINE LAYER TO DEVELOP EITHER SATURDAY NIGHT OR SUNDAY
NIGHT.

.LONG TERM (SUNDAY-WEDNESDAY)...

THE LONG WAVE PATTERN DOES READJUST SOME FOR NEXT WEEK AS A SERIES
OF TROUGHS PUSH INTO THE PACIFIC NORTHWEST AND THE ASSOCIATED FRONTS
EXTEND DOWN INTO NORTHERN AND CENTRAL CALIFORNIA. THE FIRST COLD
FRONT OF INTEREST TAKES AIM ON THE NORTHERNMOST FRINGES OF OUR
REGION EARLY MONDAY SO I ADDED A SLIGHT CHANCE OF SHOWERS TO SAN
LUIS OBISPO COUNTY. THE INCREASED TROUGH ACTIVITY ALONG THE WEST
COAST WILL ALSO RESULT IN COOLER TEMPERATURES THROUGH MUCH OF THE
EXTENDED PERIOD. THERE IS ANOTHER SLIGHT CHANCE OF SHOWERS IN THE
FORECAST FOR SAN LUIS OBISPO COUNTY ON WEDNESDAY. OTHERWISE...THE
SERIES OF TROUGHS WILL NOT PUSH FAR ENOUGH SOUTH TO IMPACT THE REST
OF THE AREA AND MOST OR THE REGION WILL STAY DRY THROUGH THE
EXTENDED PERIOD.

&&

.AVIATION...07/1740Z...
MODERATE TO HIGH CONFIDENCE IN CAVU TAFS THROUGH THE PERIOD.

THERE WILL BE SOME SURFACING OF GUSTY N-NE WINDS AT MANY OF THE
AIRFIELDS ACROSS THE FORECAST AREA THROUGH THIS AFTERNOON. THERE IS
A 30 PERCENT CHANCE THAT GUSTS WILL PERSIST +/- 2 HOURS FROM TAF
TIMES. THERE WILL ALSO BE SOME LLWS/TURBULENCE ISSUES NEAR THE
MOUNTAIN PASSES.

KLAX...MODERATE TO HIGH CONFIDENCE IN 18Z TAF. LOWER CONFIDENCE IN
THE GUSTY NW WINDS...THAT WILL LIKELY BE SPORADIC IN NATURE AND MAY
PERSIST +/- 2 HOURS FROM TAF TIME OF 20Z.

KBUR...MODERATE TO HIGH CONFIDENCE IN 18Z TAF. LOWER CONFIDENCE IN
THE TIMING OF NW WIND GUSTS BETWEEN 19Z-23Z THIS AFTERNOON.
