SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
230 AM PDT WED MAR 30 2011

.SYNOPSIS...

A WEAK TO MODERATE SANTA ANA CONDITION WILL DEVELOP TODAY THROUGH
THURSDAY. GUSTY NORTHEASTERLY CANYON WINDS AND VERY WARM TEMPERATURES
ARE EXPECTED...ESPECIALLY ON THURSDAY. FOR FRIDAY THROUGH THE WEEKEND
A COOLER ONSHORE FLOW WILL RETURN TO THE AREA. EARLY NEXT WEEK...WEAK
SANTA ANA WINDS WILL BRING ANOTHER ROUND OF WARM TEMPERATURES.

&&

.SHORT TERM (TODAY-FRI)...OVERALL...00Z MODELS IN GOOD SYNOPTIC
AGREEMENT. AT UPPER LEVELS...RIDGE WILL CONTINUE TO BUILD ACROSS
THE AREA TODAY AND THURSDAY...PEAKING AT AROUND 584 DM THURSDAY
AFTERNOON...THEN THE RIDGE WILL WEAKEN AND MOVE EASTWARD ON FRIDAY.
NEAR THE SURFACE...A WEAK TO MODERATE OFFSHORE FLOW PATTERN WILL
CONTINUE THROUGH THURSDAY...THEN TURN ONSHORE ON FRIDAY.

WITH THIS PATTERN...MAIN ISSUE WILL BE WINDS AND TEMPS. AS FOR
WINDS...CURRENTLY DECENT NORTHERLY WINDS ARE BLOWING ACROSS THE
SBA/VTU/LAX MOUNTAINS...AND ARE FILTERING INTO THE SANTA CLARITA
VALLEY. FOR TONIGHT AND THURSDAY...THE WINDS WILL TURN TO THE
NORTHEAST WITH THE FOCUS ACROSS VTU/LAX COUNTIES. AT THIS TIME...
THE NORTHEAST WINDS TONIGHT SHOULD BE ABLE TO REACH ADVISORY LEVELS
ACROSS THE VALLEY AREAS DUE TO GOOD GRADIENTS AND DECENT UPPER
SUPPORT. WITH MORNING FORECAST...WILL CONTINUE WITH ADVISORY FOR
VTU/LAX MOUNTAINS THRU THURSDAY AFTERNOON...AND SOUTHERN SANTA
BARBARA COUNTY THRU 10 AM THIS MORNING. WILL EXTEND THE ADVISORY
FOR THE SANTA CLARITA VALLEY/SANTA MONICA MOUNTAINS THRU THURSDAY
AFTERNOON. IN ADDITION...WILL ISSUE AN ADVISORY FOR THE VENTURA
VALLEYS AND SAN FERNANDO VALLEY. THE OFFSHORE WINDS SHOULD BEGIN
TO DIMINISH RATHER QUICKLY THURDAY AFTERNOON/EVENING.

AS FOR TEMPS...THE COMBO OF OFFSHORE FLOW AND STRONG UPPER LEVEL
RIDGE WILL PRODUCE SOME VERY WARM TEMPS TODAY AND ESPECIALLY
THURSDAY. IN FACT...ON THURSDAY SOME VALLEY AREAS SHOULD BE ABLE
TO CLIMB INTO THE LOWER 90S. ON FRIDAY...THERE WILL BE SOME
SIGNIFICANT COOLING WEST OF THE MOUNTAINS AS RIDGE WEAKENS AND
ONSHORE FLOW RETURNS...BUT WILL STILL BE A FEW DEGREES ABOVE
SEASONAL NORMS.

AS FOR CLOUDS...SCATTERED HIGH CLOUDS SHOULD DIMINISH LATER TODAY
WITH A GENERAL CLEAR SKY EXPECTED THIS AFTERNOON THRU FRIDAY. THE
OFFSHORE FLOW IS ONCE AGAIN PRODUCE SOME CLOUDS ACROSS INTERIOR
SECTIONS THIS MORNING...BUT THESE CLOUDS SHOULD DISSIPATE BY THIS
AFTERNOON.

.LONG TERM (SAT-TUE)...NOT MUCH CHANGE TO THE FORECAST REASONING FOR
THE EXTENDED. THROUGH SUNDAY...GFS AND ECMWF ARE IN PRETTY GOOD
AGREEMENT...DEVELOPING UPPER LEVEL TROUGH OVER THE WEST COAST WITH A
RETURN OF DECENT ONSHORE FLOW. THIS WILL RESULT IN PARTLY CLOUDY
SKIES ALONG WITH A RETURN OF SOME STRATUS FOR THE COAST AND VALLEY
AREAS. FOR SATURDAY AND SUNDAY...TEMPS WILL BE NOTICEABLY COOLER
NEAR OR SLIGHTLY BELOW SEASONAL NORMS. MOISTURE IS RATHER LIMITED
WITH THIS TROUGH...SO NO MEASURABLE RAIN IS ANTICIPATED.

FOR MONDAY AND TUESDAY...MODELS DEVELOP A WEAK UPPER LOW OVER THE
EASTERN PACIFIC. THE ECMWF KEEPS THIS FEATURE SPINNING WELL OFFSHORE
THRU TUESDAY WHILE THE GFS TRIES TO CREEP IT TOWARDS THE COAST.
EITHER SOLUTION WILL RESULT IN A WEAK OFFSHORE PATTERN ACROSS THE
AREA WHICH WILL HELP TEMPS REBOUND TO ABOVE NORMAL LEVELS ON MONDAY
AND TUESDAY...AND PRODUCE SOME CANYON WINDS. AS FOR CLOUDS...EXPECT
MOSTLY CLEAR SKIES MONDAY AND TUESDAY...ALTHOUGH THERE COULD BE SOME
INCREASE IN HIGH CLOUDS ON TUESDAY.

.AVIATION...WILL BE UPDATED WITH THE 12Z TAF PACKAGE.
