SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
910 PM PDT SUN JUN 2 2013

.SYNOPSIS...

A WEAK UPPER LEVEL LOW OFF THE CALIFORNIA COAST WILL RESULT IN
ONSHORE FLOW AND COOLER WEATHER THROUGH MID WEEK. LOW CLOUDS AND
FOG WILL PENETRATE INTO THE INTERIOR VALLEYS AND FOOTHILLS EACH
NIGHT...THEN LIKELY CLEAR TO THE BEACHES IN THE AFTERNOON. A
DECREASE IN MARINE LAYER CLOUD COVERAGE AND WARMER WEATHER IS
EXPECTED LATE IN THE WEEK AND NEXT WEEKEND...AS HIGH PRESSURE
BUILDS OVERHEAD.

&&

.UPDATE...

THE PACKAGE IS IN GOOD SHAPE THIS EVENING AS STRONG ONSHORE FLOW
REMAINS IN PLACE FROM A WEAK TROUGH OF LOW PRESSURE OFF THE
CALIFORNIA COAST. MARINE LAYER STRATUS IS SURGING INTO THE COASTS
AND VALLEY THIS EVENING AS THE MARINE LAYER DEEPENS AHEAD OF THE
TROUGH. A MARINE LAYER DEPTH NEAR 2500 FEET ON KLAX AMDAR SOUNDING
THIS EVENING SHOULD CONTINUE TO DEEPEN SOUTH OF POINT CONCEPTION
AS NAM BUFR TIME HEIGHT SECTIONS INDICATE TO BETWEEN 3000 AND 3500
FEET BY MONDAY MORNING. NORTH OF POINT CONCEPTION...THE MARINE
LAYER IS SLIGHTLY SHALLOWER...NEAR 2000 FEET...BUT SHOULD DEEPEN
TO NEAR 3000 FEET BY MONDAY MORNING. WITH A DEEPER MARINE LAYER
AND STRONGER ONSHORE FLOW IN PLACE ON MONDAY...A COOLING TREND
SHOULD PERSIST INTO MONDAY.

ACROSS THE MOUNTAINS AND DESERT...GUSTY ONSHORE WINDS JUST BELOW
ADVISORY LEVELS SHOULD CONTINUE THROUGH MONDAY AFTERNOON AND
EVENING. LOCAL ADVISORY LEVEL WIND GUSTS WILL LIKELY OCCUR AGAIN
ON MONDAY AFTERNOON AND EVENING IN THE FOOTHILLS OF THE ANTELOPE
VALLEY AS ONSHORE SURFACE PRESSURE GRADIENT SURGE TO NEAR 9 MB
ONSHORE BETWEEN KLAX-KDAG. NO UPDATES ARE PLANNED AT THIS TIME.

&&

.PREV DISCUSSION...

SHORT TERM...BY TUESDAY...MODELS ARE HINTING AT LESS MARINE
LAYER...BUT WITH ALL THE USUAL PARAMETERS (ONSHORE GRADIENTS AND
500 MB HEIGHTS) STILL FAVORING A DEEP MARINE LAYER...EXPECTING
LITTLE CHANGE FROM MONDAY EXCEPT FOR POSSIBLY BETTER CLEARING AS
THE LOW STARTS TO MOVE THROUGH THE AREA LATE IN THE DAY...WHICH
WOULD RESULT IN A TOUCH OF WARMING.

AS HEIGHTS RECOVER WITH THE LOW MOVING TO THE EAST...WARMER
TEMPERATURES ARE ON TRACK FOR WEDNESDAY...FOCUSED AWAY FROM THE
COAST. THE MARINE LAYER SHOULD SHRINK SOME...BUT WILL STILL PUSH
DEEP INTO THE VALLEYS IN THE MORNING. FORECAST REFLECTS GOOD
CLEARING IN THE AFTERNOON...BUT THIS MAY PROVE TO BE OPTIMISTIC
WITH WEAKER BUT STILL STRONG ONSHORE GRADIENTS.

LONG TERM...THE AFOREMENTIONED LOW WILL SLOWLY WEAKEN AND MOVE TO
THE SOUTH FOR THE MIDDLE TO END OF THE WEEK...WHILE A STRONG 590+
DM RIDGE BUILDS IN FROM THE NORTHWEST. THIS SHOULD GRADUALLY
WEAKEN OUR ONSHORE GRADIENTS AND SHRINK THE LOW CLOUDS AND FOG
COVERAGE DOWN TO COASTAL AND SELECT VALLEY AREAS BY THE WEEKEND.
THIS ALL SPELLS WARM UP...FOCUSED OVER THE INTERIOR AREAS WHERE
TRIPLE DIGIT HEAT IS ON TARGET. COASTAL AREAS AND NEARBY VALLEYS
WILL BE HEAVILY DEPENDENT ON HOW THE MARINE LAYER BEHAVES...AND
REALLY WONT HAVE A GOOD HANDLE ON THIS FOR ANOTHER FEW DAYS.

WITH THE ORIENTATION OF THE HIGH AND LOW...EASTERLY FLOW WILL SET
UP ALOFT OVER THE WEEKEND. WHILE MODELS ARE PROJECTING DRY AIR
UPSTREAM...ANY MOISTURE OVER NORTHERN MEXICO WILL HAVE A CHANCE
TO STREAM IN. CONSIDERING IT IS JUNE...THE DRY MODELS MAKE SENSE
AND CANNOT EXPECT MUCH MOISTURE TO BE AVAILABLE.

&&

.FIRE WEATHER...

ONSHORE FLOW STRENGTHENING THIS AFTERNOON ACROSS THE REGION. AS
OF 3 PM...LAX-DAGGETT GRADIENT ALREADY AT +8.2 MB AND IS
FORECASTED TO PEAK AROUND +9 MB BY LATE AFTERNOON. THE STRONGEST
ONSHORE WINDS THIS AFTERNOON AND EVENING WILL OCCUR ACROSS THE
MOUNTAINS AND DESERTS WHERE GUSTS BETWEEN 30 AND 40 MPH WILL BE
COMMON. ISOLATED GUSTS AS HIGH AS 50 MPH WILL BE LIKELY NEAR LAKE
PALMDALE. THE STRONGER ONSHORE FLOW HAS BROUGHT SUBSTANTIAL
COOLING AND HIGHER HUMIDITIES TO COASTAL AND VALLEY AREAS
TODAY...HOWEVER THESE TRENDS HAVE BEEN LIMITED ACROSS THE
MOUNTAINS AND DESERTS. SIMILAR GUSTY ONSHORE WINDS AND ONLY
SLIGHTLY HIGHER HUMIDITIES ARE EXPECTED ON MONDAY ACROSS THE
MOUNTAINS AND ANTELOPE VALLEY. AS A RESULT...ELEVATED FIRE DANGER
WILL CONTINUE THROUGH MONDAY FOR THE MOUNTAINS AND ANTELOPE
VALLEY DUE TO THE GUSTY ONSHORE WINDS AND RELATIVELY LOW
HUMIDITIES.

MORE SPECIFICALLY NEAR THE POWERHOUSE FIRE...ONSHORE WINDS
GUSTING TO BETWEEN 30 AND 40 MPH CAN BE EXPECTED THIS AFTERNOON
AND EVENING. WHILE CONDITIONS WILL NOT BE QUITE AS HOT AND DRY AS
YESTERDAY...HUMIDITIES WILL STILL BE IN THE 20-30 PERCENT RANGE
THIS AFTERNOON. AS THE MARINE LAYER DEPTH INCREASES
OVERNIGHT...HUMIDITY LEVELS ARE EXPECTED TO RISE TO AROUND 70
PERCENT ACROSS LOWER ELEVATIONS OF THE FIRE. HOWEVER...HUMIDITY
LEVELS WILL REMAIN AROUND 40 PERCENT ACROSS UPPER ELEVATIONS OF
THE FIRE. HUMIDITIES WILL GENERALLY RANGE BETWEEN 25-35 PERCENT
ON MONDAY. GRADUAL WARMING AND DRYING TREND ON TUESDAYS AND
WEDNESDAY WITH HUMIDITIES FALLING BACK INTO THE TEENS.

&&

.AVIATION...02/0600Z.

THE UPDATED DISCUSSION WILL BE ISSUED SOON.
