SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
215 PM PDT THU AUG 16 2007

.SHORT TERM...(TODAY-SUNDAY)
EXTENSIVE SMOKE PLUME FROM ZACA FIRE AFFECTING PORTIONS OF SANTA
BARBARA...VENTURA...AND WESTERN LOS ANGELES TODAY. WHILE VERY WARM
AIR MASS IN PLACE...THIS THICK SMOKE SHIELD HAS ONCE AGAIN MODERATED
TEMPERATURES DOWN A FEW DEGREES. HOWEVER...VERY WARM TEMPERATURES
HAVE BEEN OBSERVED ACROSS SOME COASTAL AREAS OF SLO COUNTY...WITH
PORT SAN LUIS AND PISMO BEACH REPORTING 88 DEGREES THIS PAST HOUR. 12Z
VANDENBERG SOUNDING DID INDICATE SIGNIFICANT WARMING IN THE BOUNDARY
LAYER WITH A WEAK OFFSHORE FLOW COMPONENT ABOVE THE SURFACE.

WITH GALE FORCE WINDS ALREADY BEING OBSERVED ACROSS THE OUTER COASTAL
WATERS TODAY...MAIN CONCERN IN SHORT TERM WILL BE GUSTY WINDS ACROSS
SBA COUNTY TONIGHT. A MODERATE NORTHWEST PRESSURE GRADIENT IS EXPECTED
THIS EVENING ACROSS SBA COUNTY...WITH AN INCREASING NORTH TO
NORTHEAST GRADIENT OVERNIGHT AS SURFACE HIGH PRESSURE BUILDS INTO
THE SOUTHERN SAN JOAQUIN VALLEY. WITH THE GUSTY WINDS ALREADY BEING
OBSERVED ACROSS THE COASTAL WATERS AND CENTRAL COAST...FEEL THERE IS
INCREASING CONFIDENCE FOR A SOMEWHAT STRONGER SUNDOWNER WIND EVENT
ACROSS SBA COUNTY TONIGHT AS COMPARED TO THE LAST FEW NIGHTS. OTHER
SUPPORTING INGREDIENTS INCLUDE 20 TO 30 KNOT WIND SUPPORT AT 950 MB
AS WELL AS FAVORABLE SOUTHWEST FLOW AT 500 MB. AT THIS TIME...IT
APPEARS THAT FAVORABLE NORTH-SOUTH PASSES OF SOUTHERN SBA COUNTY
COULD SEE WIND GUSTS IN THE 40 TO 45 MPH RANGE TONIGHT. EVEN AREAS
NEAR THE ZACA FIRE COULD EXPERIENCE NORTH TO NORTHEAST WINDS 15 TO
25 MPH WITH LOCAL GUSTS IN THE 35 MPH RANGE LATER TONIGHT. WITH VERY
WARM AIR MASS IN PLACE...TEMPERATURES COULD SOAR INTO THE LOWER 90S
THIS EVENING IN THE FOOTHILLS AND WIND EXPOSED AREAS...WITH
HUMIDITIES FALLING INTO THE SINGLE DIGITS AND TEENS IN DOWNSLOPE
AREAS. HAVE ISSUED A WIND ADVISORY FOR THE PASSES AND CANYONS OF
SOUTHERN SBA COUNTY FOR TONIGHT (LAXNPWLOX). WITH THE INCREASING
LAX-BAKERSFIELD GRADIENT ANTICIPATED...OTHER WIND CONCERN OVERNIGHT
AND FRIDAY MORNING WILL BE THE INTERSTATE 5 CORRIDOR IN THE LOS
ANGELES COUNTY MOUNTAINS...WHERE WIND GUSTS OVER 40 MPH WILL BE
POSSIBLE.

HAVE REMOVED ALL MENTION OF THUNDERSTORMS AS SATELLITE IMAGERY ONLY
SHOWS SHALLOW CUMULUS BUILDUPS ACROSS EASTERN LA COUNTY MOUNTAINS AND
ANTELOPE VALLEY TODAY...DUE TO LACK OF INSTABILTY. ANOTHER VERY WARM
DAY OBSERVED ACROSS INTERIOR PORTIONS OF THE FORECAST AREA...WITH
WARMEST VALLEYS AND MOUNTAINS (AWAY FROM SMOKE) ONCE AGAIN TOPPING
THE CENTURY MARK. WITH ANTICIPATED INCREASE IN NORTHERLY PRESSURE GRADIENT
OVERNIGHT AND FRIDAY MORNING...WOULD EXPECT A WEAKER ONSHORE COMPONET
ON FRIDAY AFTERNOON. AS A RESULT...WOULD EXPECT 3 TO 5 DEGREES OF ADDITIONAL
WARMING ACROSS PORTIONS OF THE CWA...MAINLY SOUTH OF POINT
CONCEPTION. EVEN INLAND PORTIONS OF THE COASTAL PLAIN ARE EXPECTED TO
SEE SIGNIFICANT WARMING...WITH DOWNTOWN LOS ANGELES EXPECTED TO CLIMB
TO 92 DEGREES ON FRIDAY.

A WEAK UPPER LEVEL TROUGH WILL MOVE INTO NORTHERN AND CENTRAL CALIFORNIA
THIS WEEKEND...WHICH WILL GRADUALLY INCREASE THE ONSHORE FLOW AND ASSOCIATED
MARINE INFLUENCE ACROSS COASTAL AND VALLEYS AREAS. AS A
RESULT...LOOK FOR A GRADUAL COOLING TREND ACROSS MOST AREAS THROUGH THE
WEEKEND...WITH TEMPERATURES RETURNING TO NEAR NORMAL LEVELS.

.LONG TERM...(MON-THU)
UPPER LEVEL RIDGE REBUILDS ON MONDAY AND TUESDAY...RESULTING IN A WARMING
AND DRYING TREND ACROSS MUCH OF THE REGION...ESPECIALLY INLAND AREAS.
ANOTHER UPPER LEVEL TROUGH IS ANTICIPATED TO MOVE INTO NORTHERN AND
CENTRAL CALIFORNIA ON WEDNESDAY AND THURSDAY...BUT STILL NOT CLEAR ON
THE MAGNITUDE OF COOLING WITH THIS SYSTEM. FOR NOW...JUST MODERATED
TEMPERATURES 3 TO 5 DEGREES IN MOST LOCATIONS.

.AVIATION...

16/1815Z

MARINE LAYER WILL NOT IMPACT TAFS DURING THE NEXT 24 HOURS. SMOKE
LAYERS FROM 040-150 WILL PERSIST OVER SBA AND VENTURA COUNTIES. KSBA
WILL ALSO HAVE INTERMITTENT NORTH WINDS LATE THIS EVENING AND
