SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
830 PM PDT THU APR 5 2012

.SYNOPSIS...
AN UPPER LEVEL TROUGH OF LOW PRESSURE WILL BRING WINDY CONDITIONS TO
THE AREA THROUGH TONIGHT. HIGH PRESSURE WILL PROVIDE FAIR AND WARMER
CONDITIONS TO THE AREA FRIDAY INTO EARLY NEXT WEEK. A COUPLE OF LOW
PRESSURE AREAS ARE EXPECTED TO GIVE THE REGION A CHANCE OF
PRECIPITATION AND COOLER TEMPERATURES BY THE MIDDLE OF NEXT WEEK.

&&

.SHORT TERM (TONIGHT-SUN)...
A BROAD UPPER LEVEL TROUGH IS SLOWLY MOVING INLAND OVER THE REGION
THIS EVENING...AND WILL CONTINUE TO SHIFT EASTWARD OVERNIGHT INTO
FRIDAY. WHILE THE BULK OF MOISTURE WILL REMAIN WELL NORTH OF THE
FORECAST AREA...THE LOCATION OF THE TROUGH AXIS THROUGH THE CENTER
OF THE STATE SUPPORTS A STRONG NORTHERLY GRADIENT AND COLD AIR
INFLUX INTO THE AREA. GUSTY NORTHWEST TO NORTH WINDS WILL CONTINUE
OVER MUCH OF THE AREA THROUGH LATE THIS EVENING...AND AS THE TROUGH
MOVES FURTHER EAST WINDS WILL SHIFT TO THE NORTH TO NORTHEAST
THROUGH FRIDAY MORNING.

CURRENT WIND ADVISORIES LOOK ON TRACK WITH 00Z NAM CONTINUING TO SHOW
A GOOD SURGE OF NORTHERLY WINDS AND COLD AIR ADVECTION (AT 850 MB
AND 950 MB LEVELS)ACROSS THE REGION DURING THE NEXT 6 HOURS. AS THIS
OCCURS...SHOULD SEE NORTHERLY WINDS RAMP UP ACROSS THE SANTA YNEZ
RANGE AND ADJACENT SBA SOUTH COAST AS WELL AS THE INTERSTATE 5
CORRIDOR. IN ADDITION...THIS NORTHERLY SURGE OF WINDS SHOULD PUSH
INTO THE SANTA CLARITA VALLEY...SAN FERNANDO VALLEY...SANTA MONICA
MOUNTAINS...AND THE WEST SIDE OF THE LOS ANGELES COAST WITHIN THE
NEXT COUPLE OF HOURS.

LOW LEVEL FLOW WILL SHIFT TO THE NORTHEAST LATE TONIGHT INTO FRIDAY
MORNING...WITH THE FOCUS OF THE WINDS SHIFTING TO THE PASSES AND
CANYONS OF LOS ANGELES COUNTY AND EASTERN PORTIONS OF VENTURA
COUNTY. AS THIS OCCURS...SHOULD SEE A MARKED DECREASE IN WINDS
ACROSS PORTIONS OF THE FORECAST AREA. THIS REDUCTION IN WIND
COMBINED WITH AN INFLUX OF DRIER AIR THIS EVENING WILL ALLOW FOR
STRONG RADIATIONAL COOLING DURING THE LATE NIGHT AND EARLY MORNING
HOURS. FROST ADVISORIES HAVE BEEN POSTED FOR THE INTERIOR VALLEYS OF
SLO COUNTY...CUYAMA VALLEY...AND ANTELOPE VALLEY. ALL OF THESE
LOCATIONS COULD SEE A LATE-SEASON EPISODE OF WIDESPREAD
SUB-FREEZING TEMPERATURES FOR TWO OR MORE HOURS. PATCHY FROST COULD
ALSO BE SEEN IN WIND SHELTERED PORTIONS OF THE CENTRAL COAST...SANTA
YNEZ VALLEY...AND OJAI VALLEY.

*** FROM PREVIOUS DISCUSSION ***

A WARMING AND DRYING TREND WILL BEGIN ON FRIDAY AS THE UPPER LOW
MOVES QUICKLY NORTHEAST OF THE AREA...WITH ANOTHER CLOSED LOW
DEEPENING ALONG 140 W AND 42 N. AS HEIGHTS AND THICKNESS VALUES
RISE...EXPECT DAYTIME HIGHS TO RISE EACH DAY THROUGH THE SHORT
TERM...WITH UPPER 60S AND 70S ON FRIDAY AND 70S TO LOWER 80S ACROSS
THE AREA THROUGH THE WEEKEND.

.LONG TERM (MON-THU)...
MODEL AGREEMENT IS FAIRLY GOOD THROUGH THE EXTENDED...WITH THE
AFOREMENTIONED NE PACIFIC LOW NEAR 135 W AND 45 N BY 12Z MONDAY. THE
ASSOCIATED TROUGH WILL DIG SOUTH AND APPROACH THE COAST MONDAY INTO
TUESDAY AS ANOTHER LOW MOVES SOUTH ACROSS THE GULF OF ALASKA. BY
WEDNESDAY MORNING THE MODELS IN VARYING DEGREES SHOW PRECIPITATION
SPREADING INTO THE AREA AS THE UPPER TROUGH AXIS MOVES OVER THE
CALIFORNIA COAST. BASED ON RECENT RUN TO RUN CONSISTENCY...ALONG
WITH FAIRLY GOOD AGREEMENT BETWEEN MODELS...DECIDED TO PAINT CHANCE
POPS ACROSS THE AREA ON WEDNESDAY. THE MODELS WOULD LIKE TO SHIFT
THE TROUGH INLAND FAIRLY QUICKLY AS THEY BRING THE NEXT UPPER LOW
TOWARD THE N CALIFORNIA COAST. AT THIS TIME THE MODELS INDICATE
ADDITIONAL PRECIPITATION FOR FRIDAY INTO THE WEEKEND.

&&

.AVIATION...05/1800Z.
SCT LOW CLOUDS OVER EXTREME LA COUNTY WILL CLEAR IN LESS THAN ONE
HOUR. OTHERWISE...SKIES WILL BE MOSTLY CLEAR WITH VFR CONDITIONS FOR
THE NEXT 24 HOURS. THE MAIN CONCERN WILL BE THE GUSTY NORTH WINDS
WITH ASSOCIATED LOW LEVEL WIND SHEAR AND TURBULENCE.

KLAX...GOOD CONFIDENCE IN VFR CONDITIONS THROUGH FRIDAY.

KBUR...HIGH CONFIDENCE IN VFR CONDITIONS THROUGH FRIDAY.
