SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
1143 PM PDT MON MAY 4 2015

UPDATED AVIATION SECTION

.SYNOPSIS...
NIGHT THROUGH MORNING LOW CLOUDS AND FOG WILL CONTINUE THROUGH
MIDWEEK. LOW PRESSURE WILL KEEP TEMPERATURES BELOW NORMAL THROUGH
THE END OF THE WEEK. THERE WILL BE A SLIGHT CHANCE OF SHOWERS AND
MOUNTAIN THUNDERSTORMS THURSDAY THROUGH FRIDAY MORNING. A RIDGE IS
EXPECTED TO WARM TEMPERATURES TO AT OR SLIGHTLY ABOVE NORMAL BY
SUNDAY.

&&

.SHORT TERM (TONIGHT-THU)...
BROAD TROUGHING OVER THE WESTERN U.S. WILL KEEP BELOW NORMAL
TEMPERATURES ACROSS THE AREA THROUGH THIS PERIOD AND PRIOR TO A
DEEPER LOW THAT DIVES SOUTH OUT OF BRITISH COLUMBIA AND INTO CENTRAL
CALIF LATER ON THURSDAY. THIS BROAD UPPER LEVEL TROUGH HELPING TO
GENERATE STRONG ONSHORE PRESSURE GRADIENTS ACROSS SOUTHERN
CALIFORNIA TODAY...AS EVIDENT BY THE +9.2 MB LAX-DAGGETT GRADIENT
EARLIER THIS AFTERNOON. THIS STRONG ONSHORE FLOW GENERATING GUSTY
ONSHORE WINDS ACROSS INTERIOR SECTIONS...ESPECIALLY THE ANTELOPE
VALLEY. ISOLATED GUSTS AS HIGH AS 50 MPH BEING OBSERVED THIS EVENING
AT LAKE PALMDALE.

SATELLITE IMAGERY SHOWING LOW CLOUDS FILLING IN ACROSS PORTIONS OF
THE CENTRAL COAST AND ANOTHER AREA NEAR CATALINA ISLAND. LATEST
ACARS DATA SHOWING MARINE LAYER DEPTH AROUND 2000 FEET THIS EVENING
ACROSS THE LA BASIN. MODEL CROSS SECTIONS SHOWING THAT MARINE LAYER
DEPTH WILL LIKELY INCREASE TO BETWEEN 3000 AND 3500 FEET BY TUESDAY
MORNING ACROSS THE LA BASIN. THE DEEP MARINE LAYER AND STRONG
ONSHORE FLOW SHOULD ENABLE LOW CLOUDS TO FILL IN ACROSS MUCH OF THE
COAST AND VALLEYS...AS WELL AS SOME OF THE LOWER COASTAL SLOPES. 00Z
NAM ALSO SHOWING CONSIDERABLE LOW LEVEL MOISTURE LINGERING INTO
AFTERNOON HOURS...SO MAY SEE SLOWER CLEARING WITH AT LEAST PARTLY
CLOUDY SKIES LINGERING ACROSS PORTIONS OF THE COAST AND VALLEYS.
SIMILAR DEEP MARINE LAYER PATTERN WITH POTENTIAL FOR DRIZZLE BY
WEDNESDAY MORNING. THIS WILL RESULT IN CONTINUED COOLING TREND NEXT
COUPLE OF DAYS...WITH THURSDAY BEING THE COOLEST DAY AS COLD UPPER
LOW PRESSURE SYSTEM MOVES INTO THE AREA. IN ADDITION...GUSTY ONSHORE
WINDS WILL CONTINUE IN THE MOUNTAINS AND ANTELOPE VALLEY. IN
FACT...LATER SHIFTS MAY NEED TO CONSIDER A WIND ADVISORY FOR THE
ANTELOPE VALLEY DURING THE NEXT FEW DAYS.

A LOOK AT THE 00Z NAM MODEL STILL SHOWING SIGNIFICANT COLD AIR
ADVECTION ALOFT THURSDAY AFTERNOON INTO THURSDAY EVENING ASSOCIATED
WITH THE UPPER LOW DIVING SOUTHWARD INTO CENTRAL CALIFORNIA. WHILE
MOISTURE IS SOMEWHAT LIMITED...THE NAM CONTINUES TO SHOW IMPRESSIVE
INSTABILITY DURING THIS TIME. CURRENTLY HAVE SLIGHT CHANCE OF TSTMS
MENTIONED IN FORECAST FOR THE MOUNTAINS ON THURSDAY
AFTERNOON/EVENING BUT MAY NEED TO EXPAND INTO SOME OF THE VALLEYS IF
THIS FORECAST TRACK CONTINUES TO HOLD TOGETHER. IN
ADDITION...APPEARS THAT MOST ORGANIZED SHOWER AND MOUNTAIN SNOW
POTENTIAL WILL BE ACROSS LOS ANGELES COUNTY DUE TO MORE FAVORABLE
CYCLONIC FLOW PATTERN FOR THIS PORTION OF THE FORECAST AREA. FOR
THIS REASON...POPS ACROSS LA COUNTY WILL LIKELY NEED TO BE ADJUSTED
UPWARD AS WE DRAW CLOSER TO THE EVENT.

*** FROM PREVIOUS DISCUSSION ***

MODELS AGREE ON DROPPING THE CLOSED UPPER LOW JUST NORTH OF THE AREA
BY 5 PM THURSDAY. SLIGHT CHANCES OF PRECIPITATION START THURSDAY
MORNING OVER LOS ANGELES COUNTY AND NORTH INTO THE VENTURA COUNTY
MOUNTAINS AS MODELS INDICATE SOME INSTABILITY WITH THE APPROACH OF
COOLER MID LEVEL TEMPS. PRECIP CHANCES INCREASE SLIGHTLY THESE AREAS
THURSDAY AFTERNOON. HAVE ALSO ADDED A SLIGHT CHANCE OF
THUNDERSHOWERS FOR THE VENTURA COUNTY MOUNTAINS THURSDAY AFTERNOON
WITH MODEL LIFTED INDICIES OF -3 TO -4 DEG C INDICATED. NEGATIVE
LIFTEDS ARE ALSO INDICATED FOR VALLEY AREAS...THE FORECAST MODEL
SOUNDING FOR LAX VALID THUR 5 PM INDICATES A -4 LIFTED...BUT COULD
NOT QUITE PULL THE TRIGGER FOR ANY TRW- DOWN IN THE VALLEYS. AND AS
WITH ANY LOW THAT TAKES THIS PATH RIGHT ALONG OR JUST INLAND OF THE
COAST...MOISTURE WILL BE DIFFICULT TO COME BY SO NOT EXPECTING MUCH
IN THE WAY OF MEASURABLE PRECIPITATION THROUGH THURSDAY NIGHT.

.LONG TERM (FRI-MON)...
THE BEST CHANCES OF PRECIPITATION APPEAR AT THIS TIME TO BE THURSDAY
NIGHT INTO FRIDAY MORNING. THESE INCLUDE SCATTERED AREAS WITH
CHANCES NORTH OF POINT CONCEPTION WHEN THE LOW IS AT ITS CLOSEST
PROXIMITY TO THE AREA AND MOST AREAS WILL BENEFIT FROM SOME LIFT
WITH THE LOW. INCREASED POPS A BIT FROM THE PREVIOUS FORECAST BUT
KEPT BELOW LIKELY FOR NOW. JUST NOT SEEING ANY STRONG ENOUGH LIFT
INDICATORS IN THE MODELS QUITE YET.

THE CLOSED LOW SHOULD BE SITUATED OVER VEGAS BY MIDDAY FRIDAY WITH
HEIGHT RISES OVER OUR AREA. FINE TUNED THE PRECIPITATION
PROBABILITIES FOR FRIDAY...KEEPING BEST CHANCES (ALTHOUGH STILL NOT
TOO HIGH) OVER L.A. COUNTY FRIDAY AND ELIMINATING THEM NORTH OF PT
CONCEPTION. THIS IS CONTRARY TO THE ECMWF WHICH INDICATES HIGHER
POPS ACROSS MOST OF THE AREA DUE TO A VORT LOBE IT SWINGS AROUND THE
LOW DURING THE DAY FRIDAY ON TOP OF THE FACT IT KEEPS THE LOW A
LITTLE FURTHER WEST...BUT ENSEMBLE PRECIPITATION FORECASTS DO NOT
FAVOR THIS SCENARIO SO WENT WITH A NORTH TO SOUTH DRYING TREND. THE
GFS..WHICH IS FURTHER EAST...ALSO APPEARS TO BE MORE CONSISTENT OVER
ITS LAST SEVERAL RUNS.

DO NOT EXPECT ANY SIGNIFICANT PRECIPITATION TOTALS WITH THIS SYSTEM
AT THIS TIME. GENERALLY ANY AREA THAT DOES RECEIVE PRECIPITATION
SHOULD NOT GET ANY MORE THAN A QUARTER OF AN INCH WITH UNDER A TENTH
OR EVEN LESS MORE COMMON.

A SHORTWAVE RIDGE MOVES IN FOR SATURDAY AND SUNDAY TO BRING WARMING
AND DRYING EACH DAY. BY SUNDAY HIGH TEMPERATURES ARE EXPECTED TO BE
CLOSER TO JUST ABOVE NORMAL MOST AREAS...MEANING 70S COASTS AND LOW
80S INLAND VALLEYS. EXTENDED MODELS EACH SHOW SOME DEGREE OF
TROUGHING TO OUR WEST ON MONDAY BUT AT THIS TIME NOT CLOSE ENOUGH TO
BRING ANY COOLING OUTSIDE OF POSSIBLY A FEW DEGREES COOLING NORTHERN
SLO COUNTY.

&&

.AVIATION...05/0643Z.

AT 0600Z...THE MARINE INVERSION AT KLAX WAS BASED AROUND 2650 FEET.
THE TOP OF THE INVERSION WAS AROUND 5000 FEET WITH A TEMPERATURE OF
11 DEGREES CELSIUS.

PREDOMINANT MVFR CONDITIONS WILL CONTINUE TO SPREAD INTO COASTAL AND
VALLEY TERMINALS THROUGH 14Z. THERE IS A CHANCE THAT COASTAL
TERMINALS COULD STRUGGLE TO CLEAR ON TUESDAY WITH SCATTERED TO
BROKEN CEILINGS ABOVE 3000 FEET LINGERING INTO THE AFTERNOON HOURS.
GUSTY ONSHORE WINDS WITH A CHANCE LOWERING VISIBILITIES IN BLOW DUST
ARE POSSIBLE FOR THE ANTELOPE VALLEY TERMINALS.

KLAX AND KBUR...PREDOMINANT MVFR CONDITIONS WILL SPREAD IN BETWEEN
10Z AND 14Z. THERE IS A 50 PERCENT CHANCE THAT MVFR TO VFR
CONDITIONS WITH CEILINGS BELOW 5000 FEET COULD LINGER UNTIL AS LATE
AS 23Z TUESDAY.

&&

.MARINE...04/800 PM...

FOR THE OUTER WATERS...MODERATE CONFIDENCE IN WINDS INCREASING TO
SMALL CRAFT LEVELS TONIGHT. HIGH CONFIDENCE IN IN SMALL CRAFT
ADVISORY LEVELS WINDS FROM TUESDAY THROUGH THURSDAY.

FOR THE INNER WATERS...MODERATE CONFIDENCE IN WEST TO NORTHWEST
WINDS REMAINING BELOW SMALL CRAFT ADVISORY LEVELS THROUGH THE WEEK.
THERE IS A CHANCE OF WINDS INCREASING TO SMALL CRAFT ADVISORY LEVELS
ACROSS THE WESTERN SECTIONS OF THE INNER WATERS TUESDAY THROUGH
THURSDAY.

A LONG PERIOD (18-20 SECOND) SOUTHERLY SWELL WILL CONTINUE ACROSS
THE COASTAL WATERS THROUGH TUESDAY NIGHT...THEN SLOWLY SUBSIDE THE
SECOND HALF OF THE WEEK.

&&

.LOX WATCHES/WARNINGS/ADVISORIES...
HIGH SURF ADVISORY (SEE LAXCFWLOX).
BEACH HAZARD STATEMENT (SEE LAXCFWLOX).
SMALL CRAFT ADVISORY (SEE LAXMWWLOX).
