SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
830 PM PDT SAT APR 16 2011

.SYNOPSIS...
ONSHORE FLOW WILL COOL TEMPERATURES ON SUNDAY. THE TAIL END OF A
COLD FRONT WILL BRING A SLIGHT CHANCE OF SHOWERS TO THE CENTRAL
COAST AND POSSIBLE DRIZZLE WITH A DEEP MARINE LAYER SOUTH COASTS ON
MONDAY. IT WILL BE PARTLY CLOUDY AND MUCH COOLER TUESDAY AND
WEDNESDAY...THEN ANOTHER WEAK SYSTEM ARRIVES ON THURSDAY.

&&

.SHORT TERM (TONIGHT-TUE)...A RIDGE OF HIGH PRESSURE OVER THE REGION
TODAY PRODUCED VERY WARM TEMPERATURES SOUTH OF POINT CONCEPTION WITH
HIGHS REACHING AROUND 80 NEAR THE BEACHES TO THE MID 90S INLAND AND
FOOTHILLS. CQT...DOWNTOWN LOS ANGELES...SET A NEW RECORD OF 91
DEGREES. THIS BESTED THE PREVIOUS RECORD OF 90 IN 1999. NORTH OF
POINT CONCEPTION WAS NOT AS WARM...BUT STILL A VERY NICE AND SUNNY
DAY.

TONIGHT...UNDER MOSTLY CLEAR SKIES...GUSTY WINDS ARE BEING OBSERVED
AT SEVERAL MOUNTAIN AND FOOTHILL LOCATIONS. AT THIS HOUR...WE ARE
SEEING GUSTS TO 50 MPH AT WHITAKER PEAK NEAR THE GRAPEVINE AND GUSTS
TO 43 MPH IN THE FOOTHILLS OF MONTECITO. THESE WINDS ARE JUST
BEGINNING TO PEAK...BUT IF TRENDS CONTINUE...A WIND ADVISORY MAY BE
NEEDED BEFORE THE NIGHT IS OVER. OTHERWISE...MUCH OF THE REGION WILL
SEE LIGHT TO MODERATE OFFSHORE WINDS...WHICH SHOULD SERVE TO
SUPPRESS THE MARINE LAYER. THE ONLY EXCEPTION MAY BE THE DEVELOPMENT
OF A COASTAL EDDY NEAR CATALINA THAT COULD WRAP SOME LOW LEVEL
MOISTURE...MARINE CLOUDS AND PATCHY FOG INTO THE COASTAL AREAS OF LA
COUNTY LATE TONIGHT OR AROUND SUNRISE SUNDAY MORNING.

ON SUNDAY...LOOK FOR ANOTHER NICE DAY WITH WARM TEMPERATURES...BUT
NOT AS QUITE AS WARM AS TODAY. TEMPERATURES WILL RUN ABOUT 10 TO 18
DEGREES COOLER ON SUNDAY COMPARED TO TODAY AS THE SEA BREEZE KICKS
IN EARLIER IN THE DAY AND LOW-LEVEL COOLING OF 5-7 DEGREES C
INDICATED BY THE WRF. STILL...TEMPERATURES SHOULD BE AT OR SLIGHTLY
ABOVE NORMAL. EXPECT EXPECT A DEEPER MARINE LAYER TO FORM SUNDAY
NIGHT AS THE EDDY STRENGTHENS AND THE STORM SYSTEM APPROACHES THE
CENTRAL COAST.

MONDAY WILL TURN OUT FAIRLY CLOUDY WITH LIGHT SPRINKLES OR DRIZZLE
POSSIBLE MAINLY FOR AREAS NORTH OF POINT CONCEPTION. A WEAK FRONT
PASSES THROUGH THE REGION MONDAY AFTERNOON. THIS SYSTEM HAS A
PRECIPITABLE WATER PLUME THAT EXCEEDS 1 INCH WHEN IT MOVES
OVERHEAD...HOWEVER THE WINDS REMAIN NORTHWESTERLY AND THE PLUME
SHIFTS SOUTH VERY QUICKLY SO WE DO NOT EXPECT MUCH OF A
PRECIPITATION THREAT WITH THIS EVENT. TEMPERATURES WILL BE BELOW
NORMAL THROUGH TUESDAY...AND WE WILL SLOWLY DECREASE THE MOISTURE
AND CLOUDS ACROSS THE AREA.

.LONG TERM (WED-SAT)...THE UPPER AIR PATTERN AT THIS TIME HAS A
FAIRLY DEEP LONGWAVE TROUGH THROUGH THE MIDDLE PART OF THE NATION
WITH A CORRESPONDINGLY LONG AMPLITUDE RIDGE OVER THE EASTERN
PACIFIC. IT IS THIS TROUGH IN THE MIDDLE OF THE NATION THAT HAS
SPAWNED ALL OF THE SEVERE WEATHER OVER THE CENTRAL AND EASTERN
PORTIONS OF THE NATION...WHILE WE HAVE HAD SOME WARMER THAN NORMAL
WEATHER IN OUR VICINITY. THIS PATTERN WILL CHANGE SLOWLY THROUGH THE
NEXT WEEK. EXPECT THE TROUGH TO BROADEN AND FILL WITH A SIMILAR
WEAKENING OF THE RIDGE OVER THE EASTERN PACIFIC. AS A RESULT...FLOW
OVER THE REGION WILL BE FAIRLY ZONAL WITH JUST A FEW WEAK...SHORT
AMPLITUDE TROUGHS MOVING ONSHORE OVER THE PACNW. WITH THE EXCEPTION
OF SOME MINOR TIMING AND AMPLITUDE ISSUES...BOTH MEDIUM RANGE MODELS
ARE IN PRETTY GOOD AGREEMENT THROUGH THE WEEK BEFORE DIVERGING NEXT
WEEKEND.

ON WEDNESDAY...BOTH THE EC AND THE GFS MOVE A SHORT WAVE TROUGH
THROUGH THE PACNW...WITH THE TAIL END REACHING OUR REGION ON
THURSDAY. AT THIS TIME...THIS SYSTEM LOOKS DRY...WITH LITTLE CHANCE
FOR SHOWERS. BUT GUSTY WINDS AND FALLING TEMPERATURES SHOULD BE
EXPECTED WITH THE PASSAGE OF THIS SYSTEM. TEMPERATURES ON THURSDAY
SHOULD RUN 5 TO 10 DEGREES BELOW SEASONAL NORMS ACROSS MUCH OF THE
REGION. BUT ON FRIDAY AND SATURDAY...A WEAK RIDGE BUILDS IN FROM THE
PACIFIC PUSHING TEMPERATURES TO AROUND NORMAL ON FRIDAY...AND
PERHAPS 5 DEGREES ABOVE NORMAL FOR THE START OF THE WEEKEND.

&&

.AVIATION...17/0000Z.

THE UPPER LEVEL RIDGE OF HIGH PRESSURE OVER THE AREA TODAY WILL
WEAKEN AS A DRY...UPPER LEVER TROUGH MOVES THROUGH THE REGION ON
SUNDAY. MODERATE UPPER LEVEL WEST WINDS WILL SHIFT TO NORTHERLY ON
SUNDAY...THEN BACK TO NORTHWESTERLY LATE SUNDAY AS THE WEAK TROUGH
PASSES TO THE EAST. LIGHT TO MODERATE ONSHORE WINDS WILL BECOME WEAK
OFFSHORE OVER MOST OF THE AREA THIS EVENING AS A COASTAL EDDY
CIRCULATION DEVELOPS NEAR CATALINA ISLAND AFTER 17/06Z. THE
OFFSHORE GRADIENTS SHOULD SUPPRESS MUCH OF THE MARINE LAYER...
EXCEPT IN THE VICINITY OF THE LA COAST WHERE THE EDDY COULD SPREAD
SOME PATCHY MARINE LAYER CLOUDS LATE TONIGHT AND EARLY SUNDAY
MORNING...TOPS WILL RANGE FROM 012-018 SUNDAY MORNING.

KLAX...CHANCE 5SM BR AND SCATTERED 015 BETWEEN 17/13-17/20Z.

KBUR...CHANCE LLWS BETWEEN 17/02-17/10Z AND CHANCE 5SM HZ AND
SCATTERED 012 AFTER 17/14-17/18Z

VIRTUALLY CERTAIN - 95-100%
VERY LIKELY       - 80-95%
LIKELY            - 60-80%
CHANCE            - 30-60%
VERY UNLIKELY     - 20% OR LESS
