SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
840 PM PDT THU APR 26 2012

.SYNOPSIS...
AS A LOW PRESSURE SYSTEM MOVES OFF TO THE EAST...LOW CLOUDS AND FOG
ARE EXPECTED TO FORM ALONG THE LOS ANGELES COAST OVERNIGHT. FRIDAY
WILL BE DRY AND WARMER WITH NORTHWEST FLOW. AS A RIDGE OF HIGH
PRESSURE BUILDS OVER THE WEEKEND...TEMPERATURES WILL CLIMB ABOVE
NORMAL FOR MOST AREAS...ESPECIALLY ON SATURDAY. NEXT WEEK LOOKS DRY
AND COOLER.

&&

.SHORT TERM (TONIGHT-SUN)...PLENTY OF STRATOCU LINGERED THIS EVENING
OVER THE L.A. COUNTY VLYS AND MTNS AND PORTIONS OF THE VTU COUNTY
MTNS. A FEW CLOUDS WERE ALSO NOTED OVER THE SBA COUNTY MTNS AND
INTERIOR VALLEYS AS WELL. ELSEWHERE...SKIES BECAME MOSTLY CLEAR
AFTER SUNSET. OVERNIGHT...IT LOOKS LIKE THE CLOUDS SHOULD DISSIPATE
S OF THE MTNS...BUT SHOULD INCREASE ALONG THE N MTNS SLOPES AS NW TO
N FLOW INCREASES. EVEN SO...A WEAK EDDY SHOULD DEVELOP SOME MARINE
LAYER CLOUDS LATER TONIGHT ALONG THE IMMEDIATE L.A. COUNTY COAST.
BREEZY NW WINDS SHOULD ALSO LINGER THRU THE NIGHT ALONG PORTIONS OF
THE CENTRAL COAST...AND BELOW AND THRU THE PASSES AND CANYONS OF THE
SANTA YNEZ RANGE AND SBA COUNTY S COAST.

A BROAD NW FLOW ALOFT WITH INCREASING 500 MB HEIGHTS CAN BE
EXPECTED THRU FRI. AN UPPER RIDGE WILL LINGER OFF THE COAST FRI
NIGHT AND SAT...THEN WEAK UPPER LEVEL TROFFINESS WILL MOVE INTO THE
REGION FOR SAT NIGHT AND SUN. A FEW LINGERING CLOUDS ON THE N MTN
SLOPES WILL DISSIPATE FRI MORNING...WITH MOSTLY CLEAR SKIES EXPECTED
TO PREVAIL FOR THE MOST PART ACROSS THE REGION FRI THRU SUN.
HOWEVER...A FEW MARINE LAYER CLOUDS CANNOT BE RULED OUT ALONG THE
IMMEDIATE CENTRAL COAST AND L.A. COUNTY COAST SAT NIGHT AND EARLY
SUN. OFFSHORE FLOW IS EXPECTED DURING THE NIGHT AND MORNING HOURS
DURING THE PERIOD...WITH SOME GUSTY WINDS POSSIBLE BELOW AND THRU
THE PASSES AND CANYONS...ESPECIALLY FRI NIGHT AND SAT MORNING. GUSTY
SUNDOWNER WINDS WILL ALSO BE POSSIBLE FOR THE SANTA YNEZ RANGE AND
SBA COUNTY S COAST FRI EVENING AND AGAIN SAT EVENING...ALTHO IT
LOOKS LIKE WINDS FRI EVENING COULD BE STRONGER AND MAY REQUIRE A
WIND ADVISORY. TEMPS ARE FORECAST TO WARM TO NEAR NORMAL ON FRI...
THEN INCREASE TO SEVERAL DEGREES ABOVE NORMAL FOR SAT BEFORE COOLING
SLIGHTLY FOR SUN.

***FROM PREVIOUS DISCUSSION***

.LONG TERM (MON-THU)...
MODELS CONTINUE TO SHOW FAIRLY GOOD AGREEMENT IN THE LONGER RANGE
PATTERN...WITH THE ELONGATED UPPER TROUGH EXTENDING OFFSHORE OVER
THE SW CALIFORNIA COAST...PERSISTING THROUGH LATE IN THE PERIOD.
EVENTUALLY A VERY WEAK CLOSED LOW IS FORECAST TO FORM OVER THE BAJA
PENINSULA. CONDITIONS FOR SW CALIFORNIA ARE EXPECTED TO REMAIN WARM
AND DRY THROUGH THE EXTENDED...WITH COASTAL LOW CLOUDS AND FOG
AFFECTING THE SOUTHERN COASTLINE FOR THE LATE NIGHT TO EARLY MORNING
HOURS. THE LAYER WILL LIKELY DEEPEN ENOUGH TO PUSH CLOUDS INTO THE
SAN GABRIEL VALLEY.

&&

THRU FRI AT KPRB...KSBP...KSMX...KSBA AND KOXR. FOR KLAX...MVFR CIGS
