SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
330 PM PST MON NOV 8 2010

...UPDATED AVIATION DISCUSSION...

.SYNOPSIS...

SOME SHOWERS MAY LINGER ACROSS NORTHERN SLOPES OF THE MOUNTAINS
TODAY IN THE WAKE OF A FRONTAL SYSTEM. WIDESPREAD GUSTY WINDS WILL
DEVELOP THIS AFTERNOON LAST INTO TONIGHT. COOL AND MOSTLY DRY
WEATHER IS EXPECTED TONIGHT THROUGH WEDNESDAY...FOLLOWED BY WARMER
AND DRY CONDITIONS THURSDAY THROUGH SUNDAY WITH GUSTY CANYON WINDS
AT TIMES.

&&

.SHORT TERM (TODAY-THU)...POST-FRONTAL NORTHWEST WINDS INCREASING
ACROSS THE AREA TODAY AND WIND ADVISORIES ARE LOOKING GOOD. WENT
AHEAD WITH A HIGH WIND WARNING FOR THE LA/VENTURA MTNS, MAINLY
FOCUSING ON THE INTERSTATE 5 CORRIDOR REGION, WHERE GUSTS AROUND 60
MPH ARE POSSIBLE DURING THE LATE AFTERNOON AND EVENING HOURS. COLD
AIR BEHIND THE FRONT WILL SETTLE IN OVERNIGHT, BUT LINGERING
OVERNIGHT BREEZES WILL WILL PREVENT MANY AREAS FROM REACHING THE
FREEZING MARK THAT WOULD HAVE OTHERWISE. DECIDED TO KEEP THE FROST
ADVISORY GOING FOR ANY WIND PROTECTED LOCATIONS IN THE AV AND
INTERIOR SLO/SBA COUNTIES THAT STILL COULD DROP TO NEAR OR SLIGHTLY
BELOW FREEZING.

MOST AREAS SHOULD SEE A LITTLE BIT OF WARMING TUESDAY AS WINDS AND
COLD AIR ADVECTION DECREASE. A DYING COLD FRONT WILL MOVE INTO THE
CENTRAL COAST AREA TUESDAY NIGHT INTO EARLY WEDNESDAY. LATEST RUNS
HAVE TRENDED DRIER AND ALL MODELS EXCEPT FOR THE ECMWF KEEP THE AREA
COMPLETELY DRY. DECIDED TO DROP POPS BELOW 15, WHICH EFFECTIVELY
REMOVES PRECIP FROM THE FORECAST, BUT COULD STILL SEE A FEW DROPS
ACROSS SLO COUNTY DURING THAT TIME. CLEAR SKIES ACROSS THE SOUTHERN
AND EASTERN PORTION OF THE FORECAST AREA WILL ALLOW FOR ANOTHER
CHILLY NIGHT, ESPECIALLY IN WIND PROTECTED LOCATIONS.

THE PASSAGE OF THIS NEXT SYSTEM WILL BRING A BRIEF RESURGENCE TO
NORTHWEST WINDS ACROSS THE AREA, WITH ESSENTIALLY LITTLE CHANGE IN
HIGH TEMPERATURES WEDNESDAY.

HIGH PRESSURE BUILDING ACROSS THE INTERIOR WEDNESDAY NIGHT INTO
THURSDAY WILL SHIFT THE LOW LVL WINDS TO NORTHEAST AND BRING ANOTHER
ROUND OF GUSTY SANTA ANA WINDS TO THE AREA AND POSSIBLY MORE WIND
ADVISORIES. THE OFFSHORE FLOW WILL HELP TEMPS TO WARM SEVERAL
DEGREES ACROSS LOWER ELEVATIONS THURSDAY AFTER A COOL START AND
POSSIBLY SOME FROST ACROSS INTERIOR SECTIONS.

.LONG TERM (FRI-MON)...DRY OFFSHORE FLOW WITH OCCASIONAL WINDY
CONDITIONS BELOW PASSES AND CANYONS WILL CONTINUE THROUGH THE
PERIOD. GRADIENTS RELAX A BIT SUNDAY BUT ARE REINFORCED MONDAY WITH
THE PASSAGE OF ANOTHER TROF THROUGH THE GREAT BASIN. HIGHS SHOULD
WARM A FEW DEGREES EACH DAY, PEAKING IN THE LOWER 80S SATURDAY
ACROSS THE VALLEYS AND PARTS OF THE COASTAL REGION.

&&

.AVIATION...08/2330Z.

OVERALL...MODERATE TO HIGH CONFIDENCE IN 00Z TAF PACKAGE. ONLY
CONCERN THROUGH THE PERIOD WILL BE NORTHWESTERLY WINDS. EXPECT
WINDS TO PEAK THIS AFTERNOON AND EVENING...BEFORE DIMINISHING
OVERNIGHT. WITH THE WINDS...THERE WILL LIKELY BE AREAS OF
LLWS AND TURBULENCE AT COASTAL/VALLEY TAFS SOUTH OF POINT
CONCEPTION THROUGH THIS EVENING. VFR CONDS WILL PREVAIL.
