SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
1140 AM PDT MON OCT 16 2006

...UPDATED AVIATION DISCUSSION...

.SHORT TERM...
SATELLITE IMAGERY STILL INDICATING A CONSIDERABLE AMOUNT OF CLOUDS
ACROSS MUCH OF LA COUNTY THIS MORNING. ACARS SOUNDING SHOWS A 3500
FOOT MOIST LAYER WITH A FAIRLY GOOD INVERSION STILL IN PLACE. FROM
VENTURA COUNTY NORTHWARD...CLOUDS HAVE BEGUN TO SCOUR OUT...WITH
GENERALLY PARTLY CLOUDY CONDITIONS EXPECTED TODAY. 12Z VANDENBERG
SOUNDING SHOWING A FAIRLY DEEP MOIST LAYER STILL IN PLACE EVEN
ACROSS THE NORTHERN AREAS...BUT THERE IS VIRTUALLY NO INVERSION DUE
TO AN INFLUX OF COLDER AIR AT LOWER LEVELS. THIS WOULD EXPLAIN
THE LACK OF ORGANIZED CLOUD COVER FOR AREAS FROM VENTURA COUNTY
NORTHWARD.

A RATHER VIGOROUS UPPER LEVEL TROUGH WILL DEEPEN ACROSS CALIFORNIA
TODAY AND TONIGHT. MOST OF THE ENERGY WILL TRACK ACROSS THE INTERIOR
PORTION OF THE STATE...MAKING IT A CLASSIC INSIDE SLIDER PATTERN.
AS A RESULT...THIS SYSTEM WILL PACK SOME STRONG WINDS ACROSS THE
MOUNTAINS AND DESERTS. WITH ONSHORE FLOW AND UPPER LEVEL WESTERLY
FLOW INCREASING TODAY...WOULD EXPECT THE STRONGEST WINDS TO OCCUR
ACROSS THE ANTELOPE VALLEY...WHERE LOCAL WIND GUSTS OVER 45 MPH
WILL BE POSSIBLE. A WIND ADVISORY MAY NEED TO BE ISSUED FOR THE
ANTELOPE VALLEY TODAY. AS THE UPPER LEVEL FLOW TURNS MORE NORTHWESTERLY
TONIGHT...LOOK FOR WINDS TO INCREASE ACROSS ALL MOUNTAIN AREAS...
ESPECIALLY THE SBA COUNTY MOUNTAINS AND LA COUNTY MOUNTAINS (NEAR
INTERSTATE 5 CORRIDOR). THE STRONGEST UPPER LEVEL SUPPORT AND SUBSIDENCE
WILL OCCUR LATE TONIGHT AND TUESDAY MORNING...AND WIND ADVISORIES
MAY BE NEEDED FOR THE MOUNTAINS AS WELL.

AS THIS SYSTEM APPROACHES THE AREA FROM THE NORTH...THERE WILL CONTINUE
TO BE A RATHER STRONG ONSHORE PUSH WHICH SHOULD MAINTAIN A
CONSIDERABLE AMOUNT OF CLOUDS THROUGH TONIGHT ACROSS LA COUNTY. WITH
THE LOWER LEVEL FLOW TURNING MORE NORTHERLY ON TUESDAY...SHOULD SEE
THE DRYING TREND BEGIN TO SCOUR OUT CLOUDS ACROSS LA COUNTY AS WELL.
THE ONLY EXCEPTION WILL BE LINGERING CLOUDS ACROSS NORTH FACING MOUNTAIN
SLOPES.

*** FROM PREVIOUS DISCUSSION ***

THINGS SWITCH RAPIDLY TUESDAY NIGHT AS OFFSHORE FLOW SETS UP IN THE
WAKE OF INSIDE SLIDER. THIS SHOULD CLEAR THINGS OUT NICELY. COLD AIR
SURGING IN FROM THE NE AND NE UPPER LEVEL FLOW COULD MAKE THIS THE
FIRST GOOD SANTA ANA OF THE SEASON. WEDNESDAY WILL DAWN SUNNY AND
WINDY IN THE USUAL PLACES. WIND ADVISORIES WILL LIKELY BE NEEDED.
TEMPS WILL CLIMB DRAMATICALLY FROM THE RATHER COOL VALUES POSTED
TODAY AND TUESDAY...AT LEAST COASTS AND VLYS DESERTS AND MTNS WILL
WARM SOME BUT IT WILL BE TEMPERED BY THE COLD AIR ADVECTION.

.LONG TERM...
THURSDAY WILL CONTINUE BREEZY BUT A LITTLE LESS SO SINCE THE THERMAL
SUPPORT WILL HAVE ENDED.

FRIDAY THERE WILL BE NOTHING LEFT BUT OFFSHORE SURFACE FLOW. IT WILL
BE CLEAR BUT ONLY LOCALLY BREEZY.

OVER THE WEEKEND A LITTLE RIDGE POPS UP AHEAD OF A LITTLE CUT OFF
LOW THAT IS MOVING TOWARDS SOCAL. THE END OF THE OFFSHORE FLOW WILL
DRIVE TEMPS DOWN A FEW DEGREES.

&&

.AVIATION...
THE DEEP MOIST LAYER UP TO NEARLY 6000 FEET COMBINED WITH A WEAK
SURFACE INVERSION HAS RESULTED IN A LOW CONFIDENCE CEILING FORECAST.
AFTER MORNING CLEARING...CIGS ARE RETURNING TO SOME AIRFIELDS S OF
POINT CONCEPTION. WITH THE LAX-DAG GRADIENT CURRENTLY AT +6.2 AND
TRENDING ONSHORE...SEABREEZE EXPECTED TO BE STRONGER THAN NORMAL.
KPMD AND KWJF MAY EVEN SEE GUSTS OVER 30KT.

KLAX EXPECTED TO SEE CIGS AT 030 MOVING IN AND OUT FOR THE
AFTERNOON...THEN SCATTERING OUT FOR GOOD AFTER 22Z. CIGS EXPECTED TO
RETURN BY 5Z AT 025 AND LOWERING TO 015 FOR THE REMAINDER OF THE
NIGHT.
&&

.LOX WATCHES/WARNINGS/ADVISORIES...
SMALL CRAFT ADVISORY (SEE LAXCWFLOX).
