SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
800 PM PDT WED MAR 28 2007

.SHORT TERM (TODAY-SAT)...SKIES MOSTLY CLEAR ACROSS THE DISTRICT THIS
EVENING AS DRIER NORTHERLY FLOW PREVAILS. STILL EXPERIENCING SOME GUSTY
NORTHERLY WINDS LOCALLY OVER 40 MPH ACROSS SOME OF THE MOUNTAINS AND
SANTA CLARITA VALLEY THIS EVENING. DURING THE OVERNIGHT HOURS...THE LOW
LEVEL FLOW WILL TURN MORE NORTHEASTERLY. FROM MIDNIGHT TONIGHT
THROUGH NOON THURSDAY...WE WILL SEE A FAIRLY GOOD BURST OF OFFSHORE
WINDS ACROSS THE TYPICAL PASSES AND CANYONS OF LOS ANGELES AND
VENTURA COUNTIES. THE 00Z WRF IS A BIT MORE BULLISH WITH OFFSHORE
WINDS SHOWING 850 MB WINDS PEAKING AT 50 KNOTS LATER
TONIGHT ACROSS THE LA COUNTY MOUNTAINS. THE GFS IS NOT NEARLY AS
IMPRESSIVE. THERE IS SOME UPPER LEVEL SUPPORT WITH A 100 KNOT
NORTH-SOUTH JET CORE JUST TO OUR EAST. FOR NOW...WILL NUDGE UP WINDS
A BIT IN EVENING ZONE UPDATE...WITH LATER SHIFTS MAY NEEDING TO
ISSUE A WIND ADVISORY FOR THE MOUNTAINS. THIS OFFSHORE WIND EVENT
WILL BE SHORT LIVED AS UPPER LEVEL SUPPORT SHIFTS WELL EASTWARD BY THURSDAY
AFTERNOON...AND OFFSHORE GRADIENTS BEGIN TO RELAX. IN FACT...THE 00Z WRF
SHOWS A SHARP ONSHORE PUSH THURSDAY AFTERNOON AND EVENING...WHICH WILL
LIKELY BRING SMALL CRAFT ADVISORY CONDITIONS TO THE INNER COASTAL WATERS
AND BREEZY CONDITIONS ALONG COASTAL AREAS.

AS THE OFFSHORE FLOW RETURNS TO THE SOUTHLAND...LOOK FOR SUBSTANTIAL WARMING
AND DRYING ACROSS MOST AREAS ON THURSDAY. MOST COASTAL AND VALLEY
AREAS WILL CLIMB UPWARD AROUND 10 DEGREES ON THURSDAY...WITH SOME AREAS
POSSIBLY HITTING THE 80 DEGREE MARK. HUMIDITY VALUES WILL BE DOWN SUBSTANTIALLY
ON THURSDAY...WITH MANY COASTAL AND VALLEY AREAS EXPECTED TO LOWER
TO BETWEEN 10 AND 15 PERCENT...AND EVEN A FEW LOCATIONS EXPECTED TO
REACH SINGLE DIGIT HUMIDITY READINGS. WHILE THERE WILL BE HEIGHTENED
FIRE WEATHER CONCERNS LATER TONIGHT AND THURSDAY...IT DOES NOT
APPEAR AT THIS TIME THERE WILL BE THE NECESSARY DURATION CRITERIA
FOR RED FLAG CONDITIONS. WHILE ONSHORE FLOW WILL BRING SOME COOLING
TO IMMEDIATE COASTAL AREAS ON FRIDAY...THERE WILL BE LITTLE CHANGE
TO THE WARM AND DRY CONDITIONS ACROSS INLAND LOCATIONS.

*** LONG TERM FROM PREVIOUS DISCUSSION ***

.LONG TERM (SUN-WED)...HIGH PRESSURE WILL START TO BREAK DOWN,
ALLOWING ONSHORE FLOW TO RETURN. WELL EVENTUALLY START TO SEE LOW
CLOUDS RETURNING TO THE COASTAL AREAS. DAYTIME HIGHS WILL DROP
SEVERAL DEGREES, BACK TO NEAR OR EVEN SLIGHTLY BELOW NORMAL. THE
STORM TRACK WILL REMAIN WELL TO THE NORTH, BUT WE COULD SEE SOME
HIGH CLOUDS PASSING THROUGH FROM TIME TO TIME.

&&

.AVIATION...28/1730Z
ALL AIRFIELDS WILL BE VFR OVERNIGHT. MAIN CONCERN WITH TAF PACKAGE WILL
BE GUSTY NORTHERLY WINDS THAT WILL EVENTUALLY SHIFT NORTHEAST
OVERNIGHT. WHILE NORTHWEST WINDS ARE PREVAILING AT KLAX THIS
EVENING..IT DOES APPEAR THAT KLAX WILL RECIVE LIGHT NORTHEAST WINDS
OVERNIGHT AND THURSDAY MORNING...GENERALLY EXPECTED TO REMAIN BELOW
8 KNOTS. THERE IS EXPECTED TO BE A RAPID SHIFT OF WINDS TO A WESTERLY
DIRECTION AT KLAX SOMETIME AROUND 19Z ON THURSDAY...POSSIBLY REACHING
18 TO 20 KNOTS FROM THE WEST.  KBUR IS EXPECTED TO HAVE SOME NORTH
WINDS OF  10 TO 15 KNOT OVERNIGHT AND THURSDAY MORNING...AND LLWS
WILL CERTAINLY BE A FACTOR TO MONITOR CLOSELY.

.LOX WATCHES/WARNINGS/ADVISORIES...
