SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
829 PM PDT SAT JUN 2 2012

.SYNOPSIS...

OVERNIGHT LOW CLOUDS AND FOG ARE EXPECTED TO CONTINUE THROUGH EARLY
NEXT WEEK. TEMPERATURES WILL WARM A COUPLE DEGREES ON SUNDAY BEFORE
A LOW PRESSURE TROUGH COOLS TEMPERATURES ON MONDAY AND TUESDAY WITH
GUSTY AFTERNOON ONSHORE FLOW. A WEAK SURFACE HIGH PRESSURE IS
EXPECTED TO BRING WARMER TEMPERATURES AND BREEZY NORTHEAST FLOW
MIDWEEK.

&&

.UPDATE...

LOW-LEVEL NORTHWEST FLOW AND WEAK COLD AIR ADVECTION HAS SCOURED
THE MARINE LAYER INDUCED STRATUS THIS EVENING...BUT STRATUS SHOULD
FILL BACK IN OVERNIGHT THE EDDY CIRCULATION OVER THE BIGHT
REGENERATES. CURRENT PACKAGE HANDLES STRATUS COVERAGE WELL THIS
EVENING AND NO UPDATES ARE PLANNED TO HANDLE STRATUS COVERAGE.

A WIND ADVISORY REMAINS IN EFFECT THROUGH 9 PM PDT FOR GUSTY
ONSHORE WINDS. WINDS ARE DIMINISHING THIS EVENING AS ADVERTISED
AND THE ADVISORY WILL LIKELY BE ALLOWED TO EXPIRE. HOWEVER...THE
WESTERN PORTION OF THE ANTELOPE VALLEY SUCH AS POPPY PARK MAY PICK
UP AND BE NEAR ADVISORY LEVELS AFTER MIDNIGHT TONIGHT AS THE
NORTHERLY LOW-LEVEL FLOW INCREASES AND DOWNSLOPES INTO THE
WESTERN PORTION OF THE ANTELOPE VALLEY.

THE MAIN CONCERN WITH THE INCREASING LOW-LEVEL FLOW IS THE
INTERSTATE 5 CORRIDOR. LATEST NAM-WRF SOLUTIONS INCREASE BOUNDARY
LAYER WINDS FOR THIS EVENING...WITH 850 MB WINDS NEAR 40 KNOTS AND
BOUNDARY LAYER WINDS BETWEEN 30 AND 35 KNOTS THROUGH THE
INTERSTATE 5 CORRIDOR. A WIND ADVISORY FOR THE INTERSTATE
CORRIDOR IS BEING CONSIDERED CURRENTLY...BUT ANY ISSUANCE WILL
WAIT FOR ADDITIONAL DATA SOURCES TO ARRIVE THIS EVENING.

&&

.PREV DISCUSSION...

SHORT TERM...A LOW PRESSURE SYSTEM...CURRENTLY PARKED JUST WEST
OF BRITISH COLUMBIA...WILL QUICKLY SWING THROUGH NORTHERN
CALIFORNIA LATE MONDAY. SIGNIFICANT CHANGES ARE ON TAP FOR MONDAY
AND TUESDAY AS A RESULT. ON MONDAY...THE APPROACHING TROUGH SHOULD
DEEPEN THE MARINE LAYER AND EXPAND COVERAGE INTO THE COASTAL
MOUNTAIN SLOPES. THIS SHOULD ADD UP TO SOME DRIZZLE AS
WELL...ESPECIALLY OVER THE FAVORED SAN GABRIEL FOOTHILLS...WHERE
MEASURABLE PRECIPITATION IS POSSIBLE. TO THE NORTH...A WEAK FRONT
ASSOCIATED WITH THIS LOW WILL PASS THROUGH THE AREA...AND COULD
BRING A STRAY SHOWER OR TWO TO SLO COUNTY...THOUGH NOT MENTIONED
IN THE FORECAST JUST YET. TEMPERATURES WILL PLUMMET...WITH
WIDESPREAD 5 TO 15 DEGREES OF COOLING ON MONDAY...DOWN INTO WELL
BELOW NORMAL TERRITORY. AMPLE HIGH CLOUDS ARE EXPECTED ON MONDAY
AS WELL.

MOST SIGNIFICANTLY...WINDS WILL BE ON THE INCREASE MONDAY AND
TUESDAY. GUSTY AND POSSIBLE ADVISORY LEVEL WEST WINDS ARE ON TRACK
FOR MONDAY OVER MOST INTERIOR MOUNTAINS AN VALLEYS...AND POSSIBLY
THE CENTRAL COAST. THE FLOW WILL SHIFT TO THE NORTHWEST MONDAY
NIGHT...AND RESULT IN A HEALTHY SBA SUNDOWNER AND I-5 WIND
PATTERN...WHERE WIND ADVISORIES LOOK LIKELY. THESE WINDS ARE POISED
TO CONTINUE THROUGH TUESDAY NIGHT...AND SHOULD IMPACT THE ANTELOPE
VALLEY BY TUESDAY AFTERNOON AS WELL. THE AIRMASS WILL COOL ON
TUESDAY...AND INTERIOR AREAS SHOULD RESPOND WITH MORE COOLING...BUT
COASTAL AREAS WILL BE MODERATED BY THE OFFSHORE WINDS. THE MARINE
LAYER AND STRATUS WILL BE DISRUPTED BY ALL OF THIS...AND WOULD NOT
BE SURPRISE IF IT COMPLETELY SCOURS OUT ON TUESDAY...ESPECIALLY
NORTHWEST OF LA COUNTY.

LONG TERM...THE AFOREMENTIONED LOW LOOKS TO QUICKLY SCOOT OUT OF
THE AREA ON WEDNESDAY...WITH WEAK SURFACE HIGH PRESSURE BUILDING
INTO NORTHERN NEVADA. THIS SHOULD GIVE US SOME BREEZY NORTHEAST
WINDS...AND HELP OUR AREA QUICKLY RECOVER FROM TUESDAY WITH
WARMING AND DRYING THROUGH THURSDAY. NOT VERY CONFIDENT ON HOW THE
LOW CLOUDS AND FOG WILL RESPOND TO ALL OF THIS...BUT LIKELY WILL
BE LESS IN COVERAGE THAN TYPICAL FOR JUNE. TEMPERATURES SHOULD BE
ABOVE NORMAL AS A RESULT...RIGHT ON INTO THE WEEKEND.

&&
