SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
158 PM PDT FRI MAY 6 2011

.SYNOPSIS...

THE MARINE LAYER WILL DEEPEN AS A LOW PRESSURE TROUGH ADVANCES INTO
THE REGION...COOLING TEMPERATURES TO BELOW NORMAL. THERE WILL BE LOW
CLOUDS WITH PATCHY DRIZZLE IN COASTAL AREAS POSSIBLE INTO EARLY NEXT
WEEK. A HIGH PRESSURE RIDGE WILL MOVE IN BY MIDWEEK AND GRADUALLY
WARM THE REGION.

&&

.SHORT TERM (TONIGHT-MON)...
MARINE LAYER HOLDING IN THERE THIS AFTERNOON WITH ONSHORE PRESSURE
GRADIENTS NEARLY 7 MB BETWEEN LAX-DAG AND VISIBLE SATELLITE SHOWING
LOW CLOUDS PERSISTING ALONG MANY COASTAL AREAS. THE DEPTH OF THE
MARINE LAYER IS EXPECTED TO INCREASE TONIGHT SO THAT WILL PUSH
CLOUDS WELL INTO INLAND VALLEYS AND COASTAL FOOTHILLS THROUGH
SATURDAY MORNING. EXPECT ANOTHER RETREAT OF CLOUDS TO THE BEACHES BY
THE AFTERNOON. TEMPERATURES STILL REFLECTING THE MARINE LAYER
PRESENCE WITH THE MAJORITY OF AREAS SHOWING 6-12 DEGREES OF COOLING
OVER YESTERDAY. THE ANTELOPE VALLEY HAS REMAINED WARM WITH SOME
LOCALLY GUSTY SOUTHWEST WINDS THIS AFTERNOON. EXPECT STRONGER WINDS
ACROSS THE AV ON SATURDAY SO WILL GO AHEAD WITH ISSUING AN ADVISORY
FOR SOUTHWEST WIND GUSTS TO 50 MPH INTO SATURDAY NIGHT.

THINGS BEGIN TO CHANGE ON SUNDAY. A LOW PRESSURE SYSTEM CURRENTLY
OFF THE BRITISH COLUMBIA COAST BECOMES MORE ENERGIZED BY A STRONG
NORTHWESTERLY JET STREAM THAT WILL STRENGTHEN THE SYSTEM AND PUSH IT
INTO WASHINGTON SUNDAY MORNING. THE JET DIVES DOWN THE CALIFORNIA
COAST AND ACROSS THE SOUTHERN SIERRA MOUNTAINS SUNDAY AFTERNOON WITH
A COLD FRONT CROSSING OUR REGION. THE MAIN IMPACTS WILL BE GUSTY
WINDS...COOLER AIR...AND LIGHT DRIZZLE OR SPRINKLES ACROSS SOUTHERN
CALIFORNIA THROUGH MONDAY. THERE HAVE BEEN SMALL DIFFERENCES BETWEEN
MODELS...MAINLY THAT THE WRF REMAINS THE AGGRESSOR WITH THE JET
PLACEMENT MORE TO THE WEST WHICH RESULTS IN STRONGER WINDS AND
COOLER AIR FURTHER SOUTH. THE GFS/ECMWF HAVE BEEN MORE CONSISTENT TO
KEEP THE JET CORE FURTHER EAST AND THE 12Z WRF TRENDED IN THIS
DIRECTION.

THIS WILL BE A MARGINAL HIGH WIND EVENT FOR THE MOUNTAINS AND DESERT
BUT SINCE THERE COULD BE MORE TRAVELERS OUT AND ABOUT WILL GO AHEAD
WITH A WATCH SUNDAY AFTERNOON THROUGH MONDAY. STRONGEST WINDS LOOK
TO BE SUNDAY EVENING BUT WILL CONTINUE TO BE GUSTY INTO MONDAY
AFTERNOON. THE MARINE LAYER WILL BE VERY DEEP ALONG THE
COAST...ESPECIALLY SOUTH OF PT CONCEPTION WHICH COULD LEAD TO
DRIZZLE ALONG THE FOOTHILLS AND THE COAST AS THE FRONT MOVES BY LATE
SUNDAY AND SUNDAY NIGHT. CLOUDS AND LIGHT PRECIPITATION MAY LINGER
INTO MONDAY EVENING FOR THESE SAME AREAS.

.LONG TERM (TUE-FRI)...
CLOUDS WILL BEGIN TO SCOUR OUT COMPLETELY TUESDAY AS NORTHERLY FLOW
TURNS MORE OFFSHORE WHEN THE LOW PRESSURE SHIFTS EAST AND HIGH
PRESSURE BUILDS INTO THE WEST COAST. WEDNESDAY AND THURSDAY SHOULD
SEE REBOUNDING TEMPERATURES AND PLENTY OF SUNSHINE. THE HIGH
PRESSURE RIDGE SEEMS TO BE SHORT-LIVED OVER SOUTHERN CALIFORNA AS
ANOTHER STORM SYSTEM MOVES TOWARD THE PACIFIC NORTHWEST BY THE END
OF THE WEEK. THE MAIN RESULT FOR OUR REGION IS A RETURN TO ONSHORE
FLOW WITH COOLING TEMPERATURES NEAR THE COAST AND MORNING LOW CLOUDS
BY FRIDAY.

&&

.AVIATION...06/1800Z.

A MID/UPPER LEVEL TROUGH OF LOW PRESSURE UPSTREAM WILL APPROACH.
LIGHT UPPER LEVEL SOUTHWEST WINDS AND LIGHT MID LEVEL WEST WINDS
WILL PREVAIL OVER THE AREA. MODERATE ONSHORE PRESSURE GRADIENT
BETWEEN 06/21-07/04Z AND AFTER 07/21Z...OTHERWISE WEAK ONSHORE
GRADIENT. MARINE LAYER TOPS WAS AROUND 1.6KFT AND WILL DIFFER BY
APPROXIMATELY PLUS 1KFT SAT MORNING.
