WITH VERY LOW SNOW LEVELS. FOR TUESDAY THROUGH THE END OF THE

&&

.SHORT TERM (TODAY-MON)...OVERALL...00Z MODELS IN GOOD SYNOPTIC
AGREEMENT THROUGH THE PERIOD. AT UPPER LEVELS...BROAD UPPER TROUGH

COLD LOW WHICH WILL SWEEP ACROSS CENTRAL CALIFORNIA ON MONDAY. NEAR
THE SURFACE...MODERATE ONSHORE FLOW WILL PREVAIL TODAY...WITH WEAK
TO MODERATE NORTHERLY FLOW TONIGHT/SUNDAY...FOLLOWED BY EVEN
STRONGER ONSHORE FLOW ON MONDAY.

LATEST SATELLITE/SURFACE OBS INDICATE STRATUS/FOG FIRMLY ENTRENCHED
ACROSS THE COASTS/VALLEYS THIS MORNING. BY THIS AFTERNOON...EXPECT
STRATUS TO DISSIPATE TOWARDS THE COAST...WITH SOME CLOUDS LINGERING
NEAR THE COAST THROUGH LATE THIS AFTERNOON. FOR TONIGHT AND SUNDAY
THE DEVELOPING NORTHERLY FLOW SHOULD KEEP THE AREA MOSTLY CLEAR...
ALTHOUGH SOME STRATUS IS NOT OUT OF THE QUESTION ALONG THE LAX
COUNTY COAST. BY SUNDAY NIGHT AND MONDAY...EXPECT SKIES TO CLOUD
BACK UP AGAIN AS THE UPPER LOW SWINGS ACROSS THE AREA.

AS FOR PRECIP CHANCES...THE SYSTEM ON SUNDAY NIGHT/MONDAY IS SIMILAR
TO MOST SYSTEMS SO FAR THIS WINTER...LOTS OF COLD AIR BUT LIMITED
MOISTURE. ALL MODELS SPIT OUT SOME LIGHT SHOWERS ACROSS THE AREA
SUNDAY NIGHT/MONDAY...WITH VERY LIMITED PRECIP AMOUNTS. BUMPED POPS
UP TO CHANCE CATEGORY FOR ALL AREAS ON MONDAY...BUT WITH QPF AMOUNTS
OF LESS THAN ONE TENTH OF AN INCH. AS THE COLD AIR MOVES IN ON
MONDAY...THE THREAT OF THUNDERSTORMS WILL HAVE TO BE MONITORED
CLOSELY. AT THIS TIME...LEFT THUNDERSTORMS OUT OF THE FORECAST...BUT
FUTURE SHIFTS MAY HAVE TO INCLUDE SOME MENTION OF THUNDER IF MODELS
MAINTAIN THEIR CURRENT THINKING.

ON SUNDAY NIGHT/MONDAY MORNING...SNOW LEVELS WILL TAKE A DRAMATIC
TUMBLE...FALLING TO BETWEEN 2500 AND 3500 FEET. GIVEN THE EXPECTED
LIMITED QPF...DO NOT ANTICIPATE ANY SIGNIFICANT OR WIDESPREAD SNOW
ACCUMULATIONS ACROSS INLAND AREAS. HOWEVER...WOULD NOT BE SURPRISED
TO SEE SOME SNOW SHOWERS REPORTED DOWN TO THE FLOOR OF THE ANTELOPE
VALLEY AND INTERIOR FOOTHILLS ACROSS SLO/SBA COUNTIES SUNDAY NIGHT
AND MONDAY MORNING.

AS FOR WINDS...THERE WILL BE SOME DECENT ONSHORE WINDS THIS
AFTERNOON ACROSS THE MOUNTAINS AND DESERTS. IN THE FOOTHILLS OF THE
ANTELOPE VALLEY...WIND GUSTS COULD FLIRT WITH ADVISORY LEVELS THIS

THIS TIME...DO NOT ANTICIPATE ANY WIDESPREAD NORTHERLY WINDS TONIGHT
BUT GUSTS COULD APPROACH/EXCEED ADVISORY LEVELS ACROSS THE SANTA
YNEZ RANGE AND I-5 CORRIDOR. ON MONDAY...THERE WILL LIKELY BE
WIDESPREAD ADVISORY LEVEL WESTERLY WINDS ACROSS THE MOUNTAINS AND
DESERTS AS WELL AS THE COASTAL PLAIN.

AS FOR TEMPS...EXPECT THINGS TO REMAIN NOTICEABLY BELOW NORMAL
THROUGH MONDAY...WITH MONDAY THE COLDEST DAY. IT WILL DEFINITELY
FEEL LIKE A SOUTHERN CALIFORNIA WINTER.

.LONG TERM (TUE-FRI)...FOR THE EXTENDED...MODELS ARE IN GOOD
SYNOPTIC AGREEMENT...POINTING TO A RATHER UNEVENTFUL PERIOD. AT UPPER
LEVELS...LOW WILL SWING EAST OF THE AREA ON TUESDAY...WITH A BROAD
TROUGH DEVELOPING OVER THE WEST COAST THROUGH THURSDAY...THEN A RIDGE
POPS UP OVER THE EASTERN PACIFIC ON FRIDAY. NEAR THE SURFACE...MODELS
INDICATE VARYING DEGREES OF ONSHORE FLOW DURING THE DAY...FOLLOWED
BY WEAK NORTHERLY FLOW AT NIGHT.

FORECAST WISE...THINGS SHOULD BE RATHER QUIET THROUGH THE PERIOD.
THE UPPER LOW MOVES INTO THE CENTRAL UNITED STATES ON TUESDAY...SO
NO CONCERN ABOUT ANY LINGERING WRAP-AROUND PRECIP ON TUESDAY. FOR
THE REST OF THE PERIOD...DRY CONDITIONS WILL CONTINUE TO PREVAIL
WITH A GRADUAL WARMING TREND. THERE MAY BE SOME NORTH/NORTHEAST
CANYON WINDS THROUGH THE PERIOD...BUT NO SIGNIFICANT OFFSHORE WIND
