SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
950 AM PDT WED AUG 27 2014

...UPDATED AVIATION DISCUSSION...

.SYNOPSIS...

A WARMING TREND WILL CONTINUE THROUGH THE END OF THE WEEK AS HIGH
PRESSURE CONTINUES TO BUILD. A BROAD TROUGH OF LOW PRESSURE WILL
DEVELOP OVER THE WESTERN UNITED STATES OVER THE WEEKEND...LIKELY
BRINGING A RETURN OF NEAR NORMAL TEMPERATURES AND AN INCREASE IN
MARINE LAYER CLOUD COVERAGE FOR EARLY NEXT WEEK.

&&

.SHORT TERM (TODAY-FRI)...LOOKS LIKE A WARM COUPLE OF DAYS AS LIGHT
OFFSHORE FLOW, VERY SHALLOW MARINE INVERSION LESS THAN 500`, AND A
LACK OF MARINE LYR CLOUDS WILL ALL COMBINE TO HELP BOOST TEMPS UP TO
SLIGHTLY ABOVE NORMAL IN ALL AREAS. WARMER VALLEYS WILL BE PUSHING
100 AND COASTAL AREAS THAT ARE 5-10 MILES INLAND WILL PUSH 90.
FORECAST LOOKS GOOD AND NOT PLANNING ON ANY ADJUSTMENTS.

***FROM PREVIOUS DISCUSSION***

ONE MORE DAY OF WARMING AS HGTS PUSH UP TO 594 DM. LOOK FOR A DEGREE
OR TWO OF WARMING ACROSS ALL AREAS. THIS MEANS THE WARMEST VLYS WILL
SEE TRIPLE DIGIT HEAT.

LOOKS LIKE A LITTLE EDDY SPINS UP FRIDAY MORNING. THIS SHOULD BE
GOOD ENOUGH TO BRING SOME LOW CLOUDS TO THE LA COAST. THE CENTRAL
COAST WILL ALSO HAVE A LITTLE MORE CLOUDINESS AS WELL. TOTAL
SUNSHINE BY LATE MORNING. HGTS FALL AS THE RIDGE IS SHOVED SOUTHWARD
BY A PAC NW LOW AND THIS SHOULD COOL MAX TEMPS A FEW DEGREES. THE LA
COAST MAY SEE A BIGGER DROP DUE TO THE INCREASED MARINE LAYER
INFLUENCE.

.LONG TERM (SAT-TUE)...
PRETTY DULL WEATHER ON TAP FOR THE THE WEEKEND AND EARLY NEXT WEEK.
A VERY LARGE BROAD TROF SETS UP OVER THE WESTERN HALF OF THE COUNTY
AND PUSHES THE UPPER HIGH OFF TO THE SOUTHWEST. HGTS LOWER (BUT NOT
MUCH) THERE WILL BE A SLOW COOLING TREND AND A SLOW INCREASE IN
NIGHT THROUGH MORNING MARINE LAYER CLOUDINESS ACROSS THE COASTAL
PLAIN BUT EXCEPT FOR THE SANTA YNEZ THE VLYS SHOULD REMAIN CLEAR.

&&

.AVIATION...27/1650Z...

OVERALL...MODERATE TO HIGH CONFIDENCE IN 18Z TAF PACKAGE. VFR CONDS
WILL CONTINUE THRU THIS EVENING FOR ALL TAF SITES. FOR TONIGHT...ONLY
ANTICIPATE RETURN OF STRATUS/FOG TO KSMX (WITH LIFR/VLIFR CONDS
LIKELY) WHILE ALL OTHER TAF SITES SHOULD REMAIN VFR.

CHANCE OF SMALL CRAFT ADVISORY WINDS ACROSS THE WATERS NEAR POINT
CONCEPTION AS EARLY AS LATE THURSDAY AFTERNOON...WITH SMALL CRAFT

.BEACHES...27/900 AM

IMPACT THE EXPOSED SOUTH FACING SHORES NORTH OF POINT CONCEPTION AS
