SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION...
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
930 AM PST THU NOV 30 2006

.SHORT TERM (TODAY-SATURDAY)...WHILE OFFSHORE WINDS HAVE BEGUN TO DIMINISH
ACROSS MOST COASTAL AND VALLEY AREAS THIS MORNING...SOME LOCAL WIND GUSTS
OVER 50 MPH CONTINUE TO BE REPORTED IN THE MOUNTAINS. AS A RESULT...HAVE
KEPT HIGH WIND WARNING IN PLACE FOR THE MOUNTAINS THIS MORNING...BUT HAVE
DOWNGRADED THE VALLEYS TO A WIND ADVSISORY. MEANWHILE...OFFHORE WINDS
HAVE DIMINISHED CONSIDERABLY ALONG THE COAST THIS MORNING...ALLOWING THE
CANCELLATION OF THE WIND ADVISORY. STRONG OFFSHORE PRESSURE GRADIENT IN
PLACE WITH LAX-DAGGETT CURRENTLY REPORTING -6.0 MB. HOWEVER...THE UPPER
LEVEL AND THERMAL SUPPORT CONTINUE TO WEAKEN AND THIS TREND WILL
CONTINUE THROUGH THE AFTERNOON AND TONIGHT. WITH LESS COLD AIR ADVECTION
TODAY...MOST AREAS SHOULD BE A FEW DEGREES WARMER TODAY...WITH EVEN
BETTER WARMING EXPECTED ON FRIDAY.

VERY COLD TEMPERATURES OBSERVED IN WIND PROTECTED AREAS THIS MORNING.
A FEW HIGHLIGHTS INCLUDE LANCASTER AT 16 DEGREES...CUYAMA AT 23
DEGREES...AND PASO ROBLES AT 25 DEGREES. COLD AND DRY AIR MASS WILL
REMAIN IN PLACE TODAY...ALLOWING FOR SIGNIFICANT RADIATIONAL COOLING
ONCE AGAIN OVERNIGHT. WITH OFFSHORE WINDS WEAKER AND LESS
WIDESPREAD...SHOULD SEE ANOTHER ROUND OF VERY COLD TEMPERATURES IN
MUCH OF OUR CWA. IN MORNING UPDATE HAVE ISSUED ANOTHER FREEZE WARNING
FOR LATER TONIGHT FOR THE ANTELOPE VALLEY...CUYAMA VALLEY...SANTA YNEZ
VALLEY...AND SLO INTERIOR VALLEYS. AREAS UNDER A FREEZE WARNING
CAN EXPECT ANOTHER ROUND OF HARD FREEZE CONDITIONS...WITH 2 OR MORE HOURS
AT 28 DEGREES OR LESS.

*** REMAINDER FROM PREVIOUS DISCUSSION ***

OFFSHORE FLOW IS EXPECTED TO CONTINUE THROUGH THE WEEKEND. ANOTHER
TROUGH MOVING THROUGH THE GREAT BASIN SHOULD PUSH A WEAK COLD FRONT
SOUTH INTO SOUTHERN CALIFORNIA. GFS SEEMS MORE EXCITED ABOUT THE
POSSIBILITY OF THE WIND EVENT THAN THE NAM-WRF SOLUTION. GOOD COLD
ADVECTION PATTERN IS CLEARLY EVIDENT IN GFS FROM FRIDAY NIGHT INTO
SUNDAY WITH SOME UPPER LEVEL SUPPORT...BUT NAM-WRF DOES NOT SEEMS TO
AGREE ON THERMAL PATTERN AS WELL. 7 TO 9 DEGREE CELSIUS THERMAL
GRADIENT SETS UP AT 850 MB IN GFS SOLUTION WITH WINDS REACHING 30
KNOTS OFFSHORE. NAM-WRF STRENGTHENS 850 MB WINDS BUT DOES NOT
STRENGTHEN THERMAL PATTERN AS MUCH. LOOKS TO BE MAINLY ADVISORY
EVENT BUT FOR NOW...FORECAST DEEMPHASIZES EVENT FOR ONGOING EVENT.

.LONG TERM (SUNDAY-WEDNESDAY)...ONSHORE FLOW COULD RETURN SUNDAY
NIGHT IF MODELS ARE CORRECT. GFS AND NAM-WRF SUGGEST FLOW LIGHTENING
ENOUGH TO ALLOW MARINE LAYER TO RETURN. FORECAST HAS NUDGED TOWARDS
MARINE LAYER DEVELOPING BRINGING PARTLY CLOUDY SKIES IN THE NIGHT
AND MORNING INTO LOS ANGELES/VENTURA COUNTY COASTS FOR SUNDAY NIGHT
THROUGH TUESDAY.

LONG TERM SEEMS HARD TO INDICATE FOR NOW. LONGER RANGE MODELS ARE
INCONSISTENT FOR MIDDLE OF NEXT WEEK. FORECAST TRENDS TOWARDS
RETURNING MARINE LAYER MORE...COOLING MAX TEMPERATURES AND WARMING
MINIMUM TEMPERATURES.

&&

.AVIATION...VFR CONDITIONS WILL CONTINUE FOR ALL TAF SITES THROUGH
TONIGHT. OFFSHORE WINDS WILL CONTINUE TODAY...BUT WILL BE MUCH
WEAKER THAN YESTERDAY. WIND SHEAR WILL CONTINUE TO BE A CONCERN AT
KBUR AND KVNY THROUGH ABOUT 21Z...BUT SHOULD MOST SIGNIFICANT WIND
SHEAR WILL BE ABOVE 2K FT.

KLAX WILL HAVE A WEAK EAST WIND BELOW 6 KT BEFORE THE WINDS BECOME
WEST AROUND 10 KT AFTER 22Z.
