PLENTY OF LOW LEVEL MOISTURE ACROSS MUCH OF THE AREA S OF POINT
CONCEPTION THIS AFTERNOON HAS LEFT SKIES MOSTLY CLOUDY WITH ISOLATED
LIGHT SHOWERS OCCURRING ACROSS PORTIONS OF VENTURA AND LOS ANGELES
COUNTIES. ESPECIALLY ALONG THE FOOTHILLS AND MOUNTAINS OF EASTERN LA
COUNTY. SW FLOW WILL CONTINUE ACROSS LA COUNTY THIS EVENING WITH LOW
LEVEL MOISTURE CONTINUING TO LINGER OVERNIGHT. NOT EXPECTING ANY
PRECIP OVERNIGHT...BUT LOW CLOUDS AND POCKETS OF DENSE FOG COULD
DEVELOP WITH THE COPIOUS AMOUNT OF RAINFALL THAT OCCURRED YESTERDAY.
SKIES SHOULD REMAIN PARTLY CLOUDY EVERYWHERE ELSE TONIGHT. A WEAKER
FRONTAL BOUNDARY COMPARED TO LAST STORM WILL BEGIN TO MOVE INTO SLO
COUNTY LATE TONIGHT BRINGING DECENT CHANCE OF PRECIP TO THE AREA BUT
LOW RAINFALL TOTALS ARE EXPECTED WITH THIS FAST MOVING SYSTEM. THIS
SAME SYSTEM WILL CONTINUE SOUTHWARD AND MOVE INTO SBA COUNTY
THURSDAY MORNING...THEN APPROACH VTU/LA COUNTIES BY TOMORROW
AFTERNOON. WENT AHEAD AND INCREASED POPS TO CHANCE FROM SLIGHT
CHANCE AS WRF HAS SHIFTED UPPER LOW SLIGHTLY FARTHER WEST ON THE
18Z RUN TO BE MORE IN LINE WITH GFS. ALTHOUGH STORM TRACK LOOKS MORE
FAVORABLE IN LA/VTU COUNTIES...THE LOWER LEVEL WINDS ARE NOT
FAVORABLE FOR MUCH IN THE WAY OF DECENT RAINFALL TOTALS. WINDS WILL
STAY OUT OF THE NORTHWEST WITH THIS NEXT SYSTEM. EXPECT UP TO ONE
THIRD OF AN INCH OF RAINFALL N OF POINT CONCEPTION...WITH MOST AREAS
S OF POINT CONCEPTION RECEIVING NEAR A TENTH OF AN INCH WITH
LOCALLY HIGHER AMOUNTS TO A QUARTER OF AN INCH POSSIBLE. NOT
ANTICIPATING ANY FLASH FLOOD WATCHES FOR THE BURN AREAS WITH THIS
NEXT SYSTEM.

AS THIS FRONT MOVES THROUGH THE AREA...STRONG NORTHERLY WINDS WILL
BEGIN TO DEVELOP ACROSS THE LOCAL MOUNTAINS. THERE WILL BE SOME
CONCERN WITH ROAD CONDITIONS ACROSS THE I-5 CORRIDOR AS VERY GUSTY
WINDS 25 TO 40 MPH WITH LOCAL GUSTS TO 50 MPH WILL BE POSSIBLE
THURSDAY NIGHT INTO FRIDAY MORNING. ON TOP OF THAT...NORTHERLY FLOW
WILL CAUSE CLOUDS TO PILE UP AGAINST THE NORTHERN SLOPES OF
SLO/SBA/VTU AND WESTERN LA COUNTY MOUNTAINS. WITH TEMPS FALLING
RAPIDLY IN THE WAKE OF THE FRONT...SNOW LEVELS SHOULD DROP TO NEAR
4000 FT WITH LOCAL BLOWING SNOW POSSIBLE ACROSS THE I-5 CORRIDOR
THURSDAY NIGHT INTO EARLY FRIDAY MORNING. FROST ADVISORIES WILL
LIKELY BE NEEDED FOR THE CENTRAL COAST THURSDAY AND FRIDAY NIGHTS AS
LOWS WILL REACH FREEZING OR JUST BELOW. TEMPS WILL REMAIN COLD
ACROSS THE MOUNTAIN AND INTERIOR SECTIONS THROUGH FRIDAY WITH TEMPS
IN THE 50S AND 60S ACROSS THE VALLEYS AND COASTAL AREAS.

WINDS WILL BEGIN TO SHIFT OFFSHORE BY FRIDAY AND AFFECT THE
MOUNTAINS AND VALLEYS OF LA/VTU COUNTIES WITH NEAR ADVISORY LEVEL
WINDS POSSIBLE THROUGH SAT MORNING. TEMPS WILL BUMP UP SLIGHTLY
ACROSS THE VALLEYS AND COASTAL AREAS FRIDAY AND SAT...BUT SHOULD
REMAIN IN THE MID 60S.

.LONG TERM...
GFS AND ECMWF ARE IN DECENT AGREEMENT EARLY AS WEAK UPPER RIDGE
BUILDS ACROSS THE AREA. WEAK OFFSHORE GRADIENTS WILL CONTINUE
THROUGH SUNDAY AS TEMPS SHOULD WARM A FEW DEGREES IN TO THE LOWER
70S ACROSS THE LA/VTU COUNTY VALLEYS. THE MODELS BEGIN TO MOVE OUT
OF PHASE AS GFS NOW SHOWS WEAK RIDGE DEVELOPING OVER THE AREA WHILE
EURO DEVELOPS A CUT-OFF LOW OVER SO CAL. WITH MODELS THIS FAR
APART...WILL CONTINUE WITH PARTLY CLOUDY SKIES AT THIS POINT.

.AVIATION...19/2000Z

PLENTY OF RESIDUAL MOISTURE IN THE WAKE OF THE FRONT WILL CAUSE
MOSTLY CLOUDY SKIES THROUGH THE DAY. SOME SITES WILL CLEAR THIS
EVENING BEFORE LOW CLOUDS REFORM OVERNIGHT. SKIES WILL BE CLOUDY
AGAIN ON THURSDAY WITH ANOTHER SLIGHT CHANCE OF SHOWERS. CEILINGS
AND AT TIMES THE VISIBILITY WILL BE RATHER CHANGEABLE LEADING TO
