SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
1110 PM PDT SUN JUL 30 2006

.SHORT TERM (TON-WED)...NOT MUCH TO ADD FROM PREVIOUS SHIFT AND
GOING FORECAST. THE DEEP MOIST LAYER APPEARS TO HAVE DROPPED
SLIGHTLY...TO MAYBE UNDER 5500 FEET. THE UPPER LEVEL TROUGH
APPROACHING FROM THE NORTHWEST LOOKS LIKE IT WILL PROVIDE ENOUGH
DRYING NORTH OF POINT CONCEPTION TO KEEP THE CLOUD TOPS A LITTLE
LOWER UP THERE OVERNIGHT. OTHERWISE...EXPECT SIMILAR CONDITIONS TO
LAST NIGHT SOUTH OF POINT CONCEPTION WITH A GENERALLY CLOUDY SKY AND
PATCHY FOG AND DRIZZLE...ESPECIALLY IN THE MOUNTAINS BELOW 6000
FEET. THE WIND BLOWING ACROSS THE ANTELOPE VALLEY HAS DIMINISHED
BELOW ADVISORY LEVEL...BUT WILL STILL REMAIN BREEZY AND LOCALLY
GUSTY OVERNIGHT. MINOR UPDATES TO THE FORECAST WERE JUST RELEASED.

...FROM PREVIOUS DISCUSSION...

ASIDE FROM THE SLIGHTLY INCREASED COVERAGE OF THE DRIZZLE MONDAY
MORNING WE EXPECT VERY LITTLE CHANGE ACROSS OUR AREA FROM TODAY. AS
NORTHWEST FLOW INCREASES NORTH OF PT CONCEPTION AND COOL AIR FROM
THE TROF MOVES IN FROM THE NORTH, THE MARINE LYR ALONG THE CENTRAL
COAST MAY START TO MIX OUT. HARD TO SAY HOW FAR SOUTH THIS CLEARING
WILL TAKE PLACE, BUT BASED ON THE RATHER SHORT DURATION OF THE
NORTHWEST WINDS IT MAY NOT EVEN EXTEND SOUTH OF SLO COUNTY. DUE TO
THIS UNCERTAINTY WILL LEAVE CLOUD FORECAST FOR THAT AREA ALONE FOR
NOW AND WILL ADJUST LATER IF IT APPEARS CLEARING WILL MAKE IT
FURTHER SOUTH.

I DONT THINK THE IMPACT OF THE TROF WILL EXTEND SOUTH OF PT
CONCEPTION SO MARINE LYR WILL LIKELY REMAIN IN TACT, AT LEAST
THROUGH MID WEEK. WITH NORTHWEST WINDS RETURNING TO THE COASTAL
WATERS, UPWELLING OF DEEPER AND COLDER OCEAN WATER SHOULD DROP SSTS
AT LEAST 3-5 DEGREES OVER THE NEXT COUPLE OF DAYS, WITH THIS
COOLER WATER MOVING SOUTH THROUGH MID WEEK. AS A RESULT, EXPECT
OVERNIGHT LOWS TO RETURN TO MORE NORMAL LEVELS OVER THE NEXT FEW
DAYS.

.LONG TERM (THU-SUN)...WITH THE LONG WAVE TROF ALONG THE WEST COAST
LINGERING THROUGH THE WEEKEND WE EXPECT LITTLE CHANGE IN THE WEATHER
ACROSS SO CAL. EXTENDED MOS GUIDANCE INDICATES SEVERAL DEGREES OF
WARMING AT THE END OF THE WEEK, BUT THIS SEEMS OVERDONE GIVEN THE
PATTERN. A COUPLE DEGREES OF WARMING SEEMS REASONABLE AS THE MARINE
LYR SHRINKS BEHIND THE TROF PASSAGE. A DRY WEST TO SOUTHWEST FLOW
WILL PREVAIL KEEPING CONVECTION WELL EAST OF THE STATE THROUGH THE
PERIOD.

&&

.AVIATION...
THE MOIST LAYER REMAINS DEEP NEAR 060 FT TONIGHT WITH WEAK
INVERSIONS THROUGHOUT. EXPECTING MULTIPLE CLOUD LAYERS TO DEVELOP AS
A RESULT. WITH AN UPPER LEVEL TROF MOVING IN...CIGS SHOULD CLEAR OUT
A TAD EARLIER THAN ON SUNDAY ALONG THE COAST. STILL WINDY IN THE
ANTELOPE VALLEY.

KLAX ALREADY SEEING THE MULTIPLE CLOUD LAYERS WITHIN THE
INVERSION...AND WILL SEE IFR CIGS DEVELOP BY 08Z WITH CLEARING
EXPECTED IN THE AFTERNOON.

&&

.LOX WATCHES/WARNINGS/ADVISORIES...NONE.
