SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
910 AM PDT SUN APR 26 2009

.SHORT TERM (TODAY THROUGH TUESDAY)...SATELLITE IMAGERY SHOWING
PATCHES OF LOW CLOUDS ACROSS FORECAST AREA THIS MORNING...WHICH
SHOULD MOSTLY BURN OFF BY THIS AFTERNOON. STRATUS PATCHY IN NATURE
FOR THE MOMENT DUE TO WEAK INVERSION IN PLACE. AS ONSHORE FLOW INCREASES
AND INVERSION BEGINS TO BETTER REESTABLISH...LOOK FOR A MORE SOLID
AND WIDESPREAD STRATUS DECK TO DEVELOP TONIGHT AND AGAIN MONDAY NIGHT.
MARINE LAYER DEPTH EXPECTED TO BE OVER 2000 FEET TONIGHT...SPREADING LOW
CLOUDS AND FOG WELL INTO THE VALLEYS. BY LATE MONDAY NIGHT AND TUESDAY
MORNING...WILL LIKELY SEE MARINE LAYER DEEPEN TO OVER 3000 FEET...WITH
LOW CLOUDS AND FOG SPREADING INTO THE LOWER COASTAL SLOPES. UPPER
TROUGH DIGGING INTO NORTHERN AND CENTRAL CALIFORNIA ON MONDAY NIGHT
WILL HELP TO ESTABLISH NECESSARY SYNOPTIC CONDITIONS TO STRENGTHEN
THE LOW LEVEL EDDY CIRCULATION OFF THE SOUTHERN CALIFORNIA COAST.
AS A RESULT OF THE DEEPENING MARINE LAYER...COULD SEE SOME PATCHY
DRIZZLE LATE MONDAY NIGHT INTO TUESDAY MORNING...ESPECIALLY ACROSS
UPSLOPE AREAS.

THE DEEPENING MARINE LAYER AND CONTINUED STRONG ONSHORE FLOW WILL
CONTINUE TO BRING A COOLING TREND TO THE REGION DURING THE NEXT
COUPLE OF DAYS...WITH CONTINUED BREEZY CONDITIONS IN THE MOUNTAINS
AND DESERTS.

*** FROM PREVIOUS DISCUSSION ***

.LONG TERM (WEDNESDAY THROUGH SATURDAY)...FOR WEDNESDAY AND
THURSDAY...THE 00Z GFS AND ECMWF ARE IN GOOD SYNOPTIC AGREEMENT.
AT UPPER LEVELS...BOTH MODELS INDICATE A BIT OF A RIDGE BUILDING
IN FROM THE SOUTH AS H5 HEIGHTS RISE. NEAR THE SURFACE...A
GENERAL WEAK ONSHORE FLOW PATTERN WILL PREVAIL...WITH A WEAK
NORTHERLY OFFSHORE PUSH POSSIBLE THURSDAY MORNING. OVERALL...
WILL EXPECT A CONTINUATION OF THE MARINE LAYER REGIME THROUGH
THURSDAY...ALTHOUGH THE DEPTH AND AREAL EXTENT SHOULD GRADUALLY
DECREASE THROUGH THURSDAY. AS FOR TEMPS...A WARMING TREND IS
EXPECTED. BUMPED UP TEMPS FROM PREVIOUS SHIFT...BUT FUTURE
SHIFTS MAY HAVE TO BUMP TEMPS UP EVEN FURTHER IF THE GFS MOS
NUMBERS ARE ACCURATE.

FOR FRIDAY AND SATURDAY...MODEL AGREEMENT STARTS TO GO OUT
THE WINDOW. GFS ZIPS A SYSTEM ACROSS CENTRAL CALIFORNIA ON
FRIDAY...WHILE THE ECMWF MOVES A SYSTEM ACROSS THE SAME AREA
ON SATURDAY. GIVEN THE UNCERTAINTY...WILL NOT OVERTHINK THE
FORECAST...INDICATING A GENERAL PARTLY CLOUDY FORECAST WITH
NIGHT/MORNING MARINE LAYER AND SLIGHTLY COOLER TEMPS. AT THIS
TIME...ANY MENTIONABLE PRECIP CHANCES SHOULD REMAIN NORTH OF
THE CWA.

&&

.AVIATION...PATCHY STRATUS THIS MORNING WITH WK INVERSION IN PLACE
ACROSS THE REGION. WITH THE WK INVERSION...EXPECT STRATUS TO
DISSIPATE FAIRLY QUICKLY THIS MORNING.

KLAX...MVFR CIGS THROUGH MID MORNING...WITH MODERATE CONFIDENCE IN
CIGS SCATTERING BY 17Z.

KBUR...SKIES HAVE SCATTERED OUT...AND HAVE HIGH CONFIDENCE THAT
CIGS WILL NOT RETURN THIS MORNING.
