SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
205 PM PDT TUE AUG 4 2015

.SYNOPSIS...

WEAK HIGH PRESSURE WILL ALLOW FOR A SLIGHT WARM UP INTO MID-WEEK.
HEADING INTO THE WEEKEND...COASTAL CLOUDS WILL BUILD INTO THE
COASTAL VALLEYS EACH MORNING WITH CONSIDERABLY COOLER TEMPERATURES
AS LOW PRESSURE PASSES TO THE NORTH. EARLY NEXT WEEK TEMPERATURES
WILL REBOUND AS HIGH PRESSURE BUILDS BACK INTO THE REGION.

&&

.SHORT TERM (TODAY-FRI)...

AS OF 130 PM A WEAK 500MB LOW WAS CENTERED ABOUT 1000 NM W OF PT
CONCEPTION...WITH THE RIDGE AXIS OF A WEAK UPPER-LEVEL TROUGH
CENTERED OVER ARIZONA AND UTAH. SATELLITE IMAGERY WAS SHOWING A
NARROW BUT THICK BAND OF CIRRUS OVER NORTHERN SLO AND MONTEREY
COUNTIES. MOSTLY CLOUDY CONDITIONS IN SLO COUNTY THIS AFTERNOON
SHOULD GIVE WAY TO PARTLY CLOUDY THIS EVENING AS THE BAND OF CIRRUS
SHIFTS NORTH.

A WIND ADVISORY WILL BE ISSUED IN SBA COUNTY FOR MODERATE SUNDOWNER
WINDS ALONG THE SANTA YNEZ RANGE LATE THIS AFTERNOON THROUGH
TOMORROW MORNING. AT -2.7 MB...SBA-SMX IS ALREADY ABOUT 1 MB
STRONGER THAN IT WAS AT THIS TIME YESTERDAY. SBA-SMX STRENGTHENED TO
-5 MB LAST NIGHT...WHEN GUSTS OF 35-45 MPH (AND ISOLATED 55 MPH)
WERE OBSERVED THROUGH AND BELOW CANYONS AND PASSES.

NOT MUCH CHANGE EXPECTED IN THE SYNOPTIC PATTERN THROUGH
TOMORROW...THEN THE UPPER LOW WILL START TO MOVE EAST ON THURSDAY
AND MOVE OVERHEAD THROUGH SATURDAY MORNING. ONLY LOW CLOUDS/PATCHY
FOG IN THE FORECAST FOR TONIGHT IS ON THE CENTRAL COAST...BUT
WOULDN'T BE TOO SURPRISED IF SOMETHING DEVELOPED NEAR LONG BEACH.
HEIGHT/THICKNESS VALUES AND 950/850 TEMPS PEAK TOMORROW AFTERNOON.
WITH LITTLE CHANGE IN THE STRENGTH OF THE ONSHORE FLOW...TOMORROW
WILL BE THE WARMEST DAY OF THE WEEK IN MOST PLACES. THE EXCEPTION
MAY BE THE SBA SOUTH COAST...WHERE SUNDOWNER WINDS SHOULD BE WEAKER
TOMORROW AFTERNOON/EVENING.

A COOLING TREND WILL BEGIN ON THURSDAY AS THE UPPER-LOW STARTS TO
APPROACH...BUT MORE SIGNIFICANT COOLING WILL OCCUR ON FRIDAY...WITH
INLAND AREAS COOLING AS MUCH AS 5-10 DEGREES. THERE WILL ALSO BE A
BETTER CHANCE OF LOW CLOUDS AND FOG RETURNING TO THE COAST WEDS
NIGHT/THURS MORNING...BUT EVEN MORE SO BY THURS NIGHT/FRI
MORNING...WHEN THE MARINE LAYER WILL LIKELY SPREAD INTO THE VALLEYS.

SOMETHING TO KEEP AN EYE FOR THURSDAY AFTERNOON WILL BE THE
POSSIBILITY OF SOME SPRINKLES OR LIGHT SHOWERS IN LA/VTA COUNTIES.
THE NAM SPITS OUT SOME LIGHT QPF AMOUNTS IN THESE AREAS ON THURSDAY
AFTERNOON...AS IT ROTATES IN SOME MID-LEVEL MOISTURE AROUND THE
WESTERN FRINGE OF THE UPPER-LEVEL HIGH TO THE EAST. WOULDN'T BE
SURPRISED TO SEE AN INCREASE IN CLOUDS AND SOME SPRINKLES IF THIS
HAPPENS...BUT SEEMS HIGHLY UNLIKELY THAT MEASURABLE PRECIP WILL
OCCUR...SO THERE IS NO MENTION OF SHOWERS IN THE OFFICIAL FORECAST.

.LONG TERM (SAT-TUE)...

HEIGHT/THICKNESS VALUES BOTTOM OUT ON SATURDAY MORNING AS THE UPPER
LOW OPENS UP AND PASSES TO THE NORTH. WITH A DEVELOPING UPPER-LEVEL
TROUGH OFF THE PAC NW COAST AND A BUILDING RIDGE OVER NM/TX...MODELS
AGREE THAT SOUTHERN CA WILL REMAIN IN DRY SW FLOW ALOFT THROUGH
EARLY NEXT WEEK. THE BUILDING RIDGE TO THE EAST WILL RESULT IN
GRADUAL HEIGHT/THICKNESS RISES...WHICH SHOULD BRING A GRADUAL
WARMING TREND SAT-TUE. TEMPERATURES SHOULD WARM BACK TO NEAR NORMAL
IN MOST PLACES BY MONDAY OR TUESDAY. MARINE LAYER CLOUD COVERAGE
SHOULD PEAK FRIDAY NIGHT/SAT MORNING...THEN GRADUAL SHRINK THROUGH
EARLY NEXT WEEK. THERE IS AN OUTSIDE CHANCE OF SOME MONSOONAL FLOW
RETURNING BY THE MIDDLE OF NEXT WEEK.
