SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
858 PM PDT TUE OCT 4 2011

.SYNOPSIS...

A COLD STORM SYSTEM WILL ARRIVE ALONG THE CENTRAL COAST TONIGHT AND
MOVE SOUTH THROUGH EARLY WEDNESDAY AFTERNOON WITH A POTENTIAL FOR
WIDESPREAD RAINFALL AND COOL TEMPERATURES FOR WEDNESDAY.
LINGERING SHOWERS AND A SLIGHT CHANCE OF THUNDERSTORMS COULD OCCUR
THROUGH THURSDAY AS AN UNSETTLED PATTERN MAY PERSIST. DRY AND
WARMER WEATHER IS EXPECTED FROM FRIDAY THROUGH EARLY NEXT WEEK.

&&

.UPDATE...

THE LATEST INFRARED AND WATER VAPOR IMAGERY INDICATES A COLD FRONT
KNOCKING ON THE DOORSTEP OF THE NORTH COAST OF CALIFORNIA. THE COLD
FRONT...ASSOCIATED WITH A COLD TROUGH OF LOW PRESSURE OVER THE
NORTHEASTERN PACIFIC OCEAN...WILL DROP SOUTH OVERNIGHT AND ARRIVE TO
NORTHWESTERN SAN LUIS OBISPO COUNTY AROUND DAYBREAK. THE FRONT WILL
SLIDE SOUTH INTO LOS ANGELES COUNTY BETWEEN LATE WEDNESDAY MORNING
AND EARLY WEDNESDAY AFTERNOON. NAM-WRF SOLUTIONS INDICATE A MOIST
AIR MASS SPREADING OVER THE AREA AHEAD OF THE FRONTAL BOUNDARY.
NAM-WRF 850 MB MIXING RATIOS INCREASE TO 8 G/KG BY DAYBREAK OVER THE
ENTIRE AREA. NAM-WRF SOLUTIONS ALSO PUSH WEAK WARM FRONTAL BOUNDARY
ACROSS THE AREA BETWEEN 10 PM TONIGHT AND 10 AM WEDNESDAY. SOME
CONCERN EXISTS THAT POPS MAY A LITTLE TOO DRY WITH THE WARM FRONTAL
BOUNDARY...AND POPS WILL BE INCREASED SLIGHTLY ACROSS THE REGION
BETWEEN TONIGHT AND WEDNESDAY MORNING.

CLOUD COVER WILL PROBLEMATIC TONIGHT AS THE HIGHER LEVEL MOISTURE
AHEAD OF THE SYSTEM OBSCURES LOW-LEVEL STRATOCUMULUS CLOUDS ON THE
FOG PRODUCT. MOST COASTAL AND VALLEY AREAS WILL LIKELY REMAIN MOSTLY
CLOUDY THROUGHOUT TONIGHT AND INTO WEDNESDAY MORNING...BUT THE
INTERIOR SLOPES OF THE MOUNTAINS AND DESERT COULD HAVE MORE BREAKS
IN THE CLOUDINESS. AS THE WEAK WARM FRONT IS MOVING SOUTH OVER THE
AREA...THE AMOUNT OF CLOUD COVER IN THE PACKAGE SEEMS AGREEABLE FOR
NOW.

NAM BUFR QPF ESTIMATES AND LOCAL 4-KM WRF QPF DATA AGREES WELL
WITH THE CURRENT PACKAGE AND NO CHANGES ARE PLANNED AT THIS TIME.
FOR THE CURRENT TIME...ONE HALF TO ONE INCH ACROSS THE COASTAL AND
VALLEY AREAS...WITH 1 TO 2 INCHES POSSIBLE ACROSS THE MOUNTAINS
SEEM AGREEABLE.

WIND HEADLINES LOOK AGREEABLE FOR THE CURRENT TIME...BUT
ADDITIONAL HEADLINES OR EXTENSIONS MAY BE NEEDED FOR WEDNESDAY
NIGHT AS THE PRESSURE GRADIENTS TIGHTEN IN THE WAKE OF THE FRONTAL
BOUNDARY. SOUTHERN SANTA BARBARA COUNTY AND THE INTERSTATE 5
CORRIDOR WILL BE THE LIKELY CANDIDATES FOR ADDITIONAL HEADLINES
BETWEEN WEDNESDAY EVENING AND THURSDAY MORNING. NAM-WRF SOLUTIONS
INCREASE 850 MB WINDS TO 35 KNOTS ACROSS THE INTERSTATE 5 CORRIDOR
BY LATE WEDNESDAY NIGHT AND EARLY THURSDAY MORNING.

AN UPDATE WILL BE ISSUED SHORTLY TO INCREASE POPS AND WEATHER
COVERAGE BETWEEN LATE TONIGHT AND EARLY WEDNESDAY MORNING.

&&

.PREV DISCUSSION...

SHORT TERM...BY WEDNESDAY NIGHT...THE COLD FRONT SHOULD HAVE
MOVED INTO ORANGE AND SAN DIEGO COUNTIES. BEHIND THE FRONT THERE
WILL CONTINUE TO BE LINGERING LOW LEVEL MOISTURE KEEPING PARTLY
CLOUDY SKIES OVERNIGHT EXCEPT MOSTLY CLOUDY ACROSS THE MOUNTAINS.
ADDITIONAL WIND ADVISORIES WILL LIKELY BE NEEDED FOR THE
SBA/VTU/LA COUNTY MOUNTAINS AND POSSIBLY THE ANTELOPE VALLEY AS
GUSTY NORTH WINDS DEVELOP BEHIND THE FRONT. EXPECT MUCH COLDER
TEMPS AS WELL IN THE HIGH COUNTRY. ALTHOUGH THE BULK OF THE
MOISTURE WILL HAVE PASSED WITH THE COLD FRONT...SNOW LEVELS WILL
LOWER TO AROUND 5000 FT BY LATE WED NIGHT INTO THURSDAY MORNING
ACROSS THE NORTHERN SLOPES OF THE VENTURA COUNTY AND WESTERN LA
COUNTY MOUNTAINS THROUGH THE GRAPEVINE. AT THIS TIME...THE TEJON
PASS SHOULD ONLY BE AFFECTED BY GUSTY WINDS AS LIGHT SNOW SHOULD
REMAIN IN THE HIGHER FOOTHILLS.

THERE WILL CONTINUE TO BE SLIGHT CHANCE FOR THUNDERSTORM ACTIVITY
INTO EARLY THURSDAY AS A STRONG VORT MAX WRAPS AROUND THE WESTERN
PERIPHERAL OF THE EXITING UPPER LVL LOW. AGAIN...CONVECTIVE
PARAMETERS ARE NOT UNSTABLE...BUT STRONG LIFT WITH THE COLD VORT
ALOFT COULD BRING A FEW ISOALTED THUNDERSTORMS ACROSS THE
AREA...LIKELY OVER THE MOUNTAINS. THERE WILL CONTINUE TO BE SOME
LINGERING MOISTURE ACROSS THE REGION...ESPECIALLY ACROSS THE LOCAL
MOUNTAINS...SO EXPECT PARTLY CLOUDY SKIES...ESPECIALLY NEAR THE
FOOTHILLS AND MOUNTAINS. TEMPS WILL CONTINUE TO BE QUITE COOL ACROSS
THE REGION AS WELL. BY FRIDAY...HIGH PRESSURE WILL BEGIN TO BUILD IN
WITH HEIGHTS AND THICKNESS LVLS RISING. HIGH TEMPS WILL MAKE IT OUT
OF THE 60S AND INTO THE LOWER TO MID 70S IN WARMEST VALLEYS.
OFFSHORE FLOW WILL BE VERY WEAK FRIDAY MORNING.

LONG TERM...A NICE WEEKEND WILL BE IN STORE FOR SOUTHERN
CALIFORNIA AS THE UPPER LEVEL RIDGE WILL PERSIST THROUGH SATURDAY.
THE RIDGE WILL BREAKDOWN A BIT ON SUNDAY BRINGING A MORE ZONAL
FLOW ACROSS THE REGION. BUT HEIGHTS REMAIN AROUND 582DM OVERHEAD.
WEAK OFFSHORE FLOW WILL OCCUR ON SATURDAY AND SUNDAY
MORNINGS...BUT SHOULD NOT IMPACT TEMPS MUCH. FOR MON AND TUE...A
591 DM HIGH PARKS OFF THE CENTRAL COAST. BOTH GFS AND EUROPEAN ARE
IN FAIR AGREEMENT WITH THIS DEVELOPMENT. EXPECT ADDITIONAL WARMING
INTO THE 80S ACROSS VALLEYS AND ANTELOPE VALLEY.

&&

.AVIATION...05/0015Z.

NORTH OF POINT CONCEPTION...PREDOMINANTLY VFR CONDITIONS WILL
PERSIST THROUGH AT LEAST 03Z TONIGHT...THEN MVFR CONDITIONS SHOULD
BECOME MORE PREVALENT THROUGH 11Z WEDNESDAY. THERE IS A CHANCE OF

WINDS WILL OCCUR ON WEDNESDAY AFTERNOON.

SOUTH OF POINT CONCEPTION...MVFR CONDITIONS WILL BECOME MORE
PREVALENT AT COASTAL AND VALLEY TERMINALS THROUGH 06Z TONIGHT. THERE
IS A CHANCE OF IFR CONDITIONS OCCURRING AHEAD OF THE FRONTAL PASSAGE
BETWEEN 15Z AND 22Z WEDNESDAY. PERIODS OF LOW-LEVEL WIND SHEAR AND
TURBULENCE ARE POSSIBLE ON WEDNESDAY EVENING.

KLAX...MVFR CONDITIONS WILL BECOME PREVALENT BETWEEN 04Z AND 08Z
TONIGHT. THERE IS A 20 PERCENT CHANCE OF IFR CONDITIONS OCCURRING
AHEAD OF THE FRONTAL PASSAGE BETWEEN 16Z AND 20Z WEDNESDAY. A 30
PERCENT CHANCE FOR A PERIOD OF CROSS WINDS EXISTS BETWEEN 17Z AND
19Z WEDNESDAY. PERIODS OF LOW-LEVEL WIND SHEAR AND TURBULENCE ARE
POSSIBLE ON WEDNESDAY EVENING.

KBUR...MVFR CONDITIONS WILL BECOME PREVALENT BETWEEN 02Z AND 06Z

...A SECOND AND MORE POWERFUL STORM TO IMPACT SOUTHWEST CALIFORNIA
EARLY WEDNESDAY THROUGH THURSDAY MORNING...

THE NEXT UPCOMING STORM SYSTEM IS EXPECTED TO TAP INTO A GOOD SOURCE
OF MOISTURE...BRINGING THE POTENTIAL FOR WIDESPREAD RAINFALL TO
SOUTHWEST CALIFORNIA WEDNESDAY INTO WEDNESDAY EVENING. THE FAST
MOVING COLD FRONT IS EXPECTED TO BRING A 3 TO 4 HOUR PERIOD OF
STEADY RAINFALL...WITH BRIEF HEAVY RAIN POSSIBLE. BEHIND THE
FRONT...A COOL AND UNSETTLED WEATHER PATTERN WILL CONTINUE TO BRING
A CHANCE OF LINGERING SHOWERS AND A SLIGHT CHANCE OF THUNDERSTORMS
INTO THURSDAY. THIS STORM HAS THE POTENTIAL TO BRING WIDESPREAD
RAINFALL AMOUNTS BETWEEN ONE HALF AND ONE INCH ACROSS THE
REGION...WITH LOCAL AMOUNTS UP TO TWO INCHES POSSIBLE ON SOUTH AND
SOUTHWEST FACING MOUNTAIN SLOPES. IN ADDITION...THERE COULD EVEN BE
SOME EARLY SEASON SNOWFALL ACROSS THE HIGHER MOUNTAIN ELEVATIONS
WEDNESDAY NIGHT INTO THURSDAY.

HIKERS SHOULD NOT BE CAUGHT OFFGUARD WITH THIS FIRST UNSEASONABLY
COLD WINTER-LIKE STORM IN THE HIGHER ELEVATIONS OF THE LOCAL
MOUNTAINS. BE PREPARED FOR COLD WEATHER AND LIGHT SNOW ACCUMULATIONS
ABOVE 7000 FT.

THERE WILL BE GUSTY SOUTH TO SOUTHWEST WINDS IN THE MOUNTAINS AND
DESERTS...WITH GUSTS UP TO 45-50 MPH ON WEDNESDAY. THESE WEATHER
SYSTEMS WILL BRING MUCH COOLER CONDITIONS TO THE SOUTHLAND...WITH
MANY LOCATIONS EXPECTED TO SEE TEMPERATURES FALL 15 TO 30 DEGREES
BELOW SEASONAL NORMALS.

NOW IS THE TIME TO CLEAN OUT STORM DRAINS TO PREVENT LOCALIZED
URBAN FLOODING AND FINISH UP ANY OUTDOOR PROJECTS THAT COULD BE
ADVERSELY AFFECTED BY RAIN THIS WEEK. MOTORISTS SHOULD BE ALERT
FOR ESPECIALLY SLIPPERY ROADS DUE TO ACCUMULATED OIL ON THE
ASPHALT...WITH MANY LOCATIONS NOT SEEING MEASURABLE RAINFALL SINCE
LAST SPRING. ANYONE PLANNING TO TRAVEL TO THE MOUNTAINS WEDNESDAY
AND THURSDAY SHOULD CHECK THE LATEST NATIONAL WEATHER SERVICE
FORECASTS AND STATEMENTS DUE TO THE CHANGING WEATHER CONDITIONS AND
THE EARLY SEASON SNOWFALL ACROSS THE HIGHER MOUNTAIN ELEVATIONS.
