SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
940 AM PST SUN DEC 21 2014

.SYNOPSIS...
SKIES WILL BE PARTLY TO MOSTLY CLOUDY TODAY. A FEW SHOWERS ARE
POSSIBLE ON NORTHERN MOUNTAIN SLOPES. HIGH PRESSURE ALOFT WILL BRING
WARMER AND DRY CONDITIONS TO SOUTHERN CALIFORNIA MONDAY THROUGH
WEDNESDAY. GUSTY NORTHWEST TO NORTH WINDS WILL AFFECT PARTS OF THE
REGION THROUGH TONIGHT...THEN NORTHEAST WINDS WILL AFFECT VENTURA
AND LOS ANGELES COUNTIES MONDAY NIGHT THROUGH TUESDAY. COOLER
CONDITIONS ARE EXPECTED FOR CHRISTMAS DAY INTO NEXT WEEKEND.

&&

.UPDATE...ADJUSTED CLOUD COVER AND TEMPERATURES FOR TODAY. STRONG
NORTHERLY FLOW ALOFT STREAMING HIGH CLOUDS AND GENERATING A
SIGNIFICANT MOUNTAIN WAVE AND ADDITIONAL CLOUD COVER FOR VENTURA AND
LOS ANGELES COUNTIES. THIS WILL LIMIT TEMPERATURES FROM REACHING
THEIR POTENTIAL PEAK IF UNDER FULL SUNSHINE ON THIS SHORTEST DAY OF
THE YEAR AND BEGINNING OF WINTER. NORTH WINDS REMAIN GUSTY THROUGH
THE MOUNTAINS WITH GUSTS 50-55 MPH AT WHITAKER PEAK AND SANDBERG.
WINDS HAVE LET UP IN OTHER AREAS BUT EXPECT GUSTY CONDITIONS TO
REDEVELOP THIS EVENING AND INTO THE NIGHT. NORTHERLY GRADIENTS
REMAIN ROBUST INTO MONDAY MORNING WITH LAX-SFO AT -7.7 MB...THEN
NORTHEASTERLY GRADIENTS START TO INCREASE TOMORROW AS WELL.
ANTICIPATE MOST AREAS WILL DROP WIND ADVISORIES MONDAY MORNING BUT
ADDITIONAL ADVISORIES FOR NORTHEAST WINDS WILL BE HOISTED FOR MONDAY
NIGHT AND TUESDAY. STILL SEEING A FEW TIPS OF THE RAIN BUCKET ACROSS
THE NORTHERN MOUNTAINS AND THIS SHOULD CONTINUE THROUGH THE DAY.
ALSO HAVE PATCHY DENSE FOG IN THE SALINAS RIVER VALLEY WHICH SHOULD
RETURN AGAIN TONIGHT.

THE NORTHERLY JET STREAM SHIFTS EASTWARD ON MONDAY AND MODEL DATA
SHOWS LESS CLOUD COVER...EXCEPT FOR SOME LINGERING UPSLOPE ON THE
NORTH SLOPES OF THE MOUNTAINS. WITH LESS CLOUD COVER AND DOWNSLOPE
WINDS TOMORROW...TEMPERATURES WILL BE 6-10 DEGREES WARMER ON MONDAY.

***FROM PREVIOUS DISCUSSION***

OFFSHORE W-E GRADIENTS WILL INCREASE MON NIGHT/TUE...AND THE LATEST
MODELS...WITH A TROUGH IN THE ROCKIES NOW DIGGING A BIT FARTHER
WESTWARD...SHOW MORE IN THE WAY OF SUPPORT FOR GUSTY NE WINDS ACROSS
L.A. AND VTU COUNTIES MON NIGHT/TUE. AT THIS POINT...IT APPEARS THAT
WIND ADVISORIES WILL BE NEEDED FOR PORTIONS OF L.A./VTU COUNTIES.
THE LATEST MODELS ALSO SHOW SOME HEIGHT/THICKNESS FALLS AND SOME
COOLING AT 850 MB AND 950 MB. THIS MAY ACTUALLY BRING SOME SLIGHT
COOLING EVEN TO AREAS W OF THE MTNS ON TUE. HAVE KNOCKED A FEW
DEGREES OFF FORECAST MAX TEMPS FOR TUE...ESPECIALLY IN THE VLYS.

.LONG TERM (WED-SAT)...THE UPPER HIGH TO THE SW OF THE REGION WILL
HOLD INTO WED...ALTHOUGH IT WILL BEGIN TO WEAKEN. OFFSHORE FLOW AND
SOME LOCALLY GUSTY WINDS IN THE MORNING WILL TURN ONSHORE IN THE
AFTERNOON. MAX TEMPS MAY BE DOWN A COUPLE OF DEGREES ON
WED...ESPECIALLY NEAR THE COAST. A TROUGH WILL ZIP THROUGH THE PAC
NW LATE WED INTO THU...CAUSING DECENT HEIGHT FALLS ACROSS THE
FORECAST AREA...AND INCREASING ONSHORE FLOW. EXPECT MAX TEMPS TO BE
DOWN SEVERAL DEGREES ON THU...DOWN TO NEAR OR POSSIBLY SLIGHTLY
BELOW NORMAL LEVELS. ANY RAIN WILL REMAIN FAR TO THE NORTH OF THE
AREA. AS THE TROUGH MOVES QUICKLY EWD...HEIGHTS WILL SLOWLY RISE
OVER THE FCST AREA FRI AND SAT...SO EXPECT A GRADUAL WARMING TREND.
