SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
840 PM PDT WED OCT 5 2005

.SHORT TERM...CRITICAL FIRE WEATHER PATTERN CONTINUES TONIGHT WITH
OFFSHORE WINDS AND VERY LOW HUMIDITIES ACROSS MUCH OF THE FORECAST
AREA. WHILE NORTHEAST WINDS HAVE DIMINISHED SOME FROM EARLIER TODAY...
WE COULD STILL SEE WIND GUSTS OF 35 TO 40 MPH INTO THURSDAY MORNING...
MAINLY BELOW AND THROUGH THE PASSSES AND CANYONS OF LA/VTU COUNTIES.
AT THIS POINT...WIND SPEEDS ARE BELOW ADVISORY LEVELS BUT THERE MAY
BE A SLIGHT INTENSIFICATION OVERNIGHT AND THURSDAY MORNING...WHICH
COULD NECESSITATE THE NEED FOR ANOTHER WIND ADVISORY NEAR PASSES AND
CANYONS.

THE OFFSHORE WINDS BROUGHT AN EXTREMELY DRY AIR MASS TO THE FORECAST
AREA TODAY...WITH SEVERAL HOURS OF SINGLE DIGIT HUMIDITES OBSERVED
AT SEVERAL LOCATIONS. VERY POOR HUMIDITY RECOVERIES EXPECTED
OVERNIGHT...WITH SOME LOCATIONS EXPECTED TO REMAIN AT OR BELOW
15 PERCENT. WITH OFFSHORE WINDS CONTINUING INTO THURSDAY...LOOK FOR
SEVERAL MORE HOURS OF SINGLE DIGIT HUMIDITIES. THE COMBINATION OF
VERY LOW HUMIDITIES WITH THE OFFSHORE WINDS HAS PROMPTED THE
CONTINUATION OF THE RED FLAG WARNING INTO EARLY THURSDAY EVENING
ACROSS THE MOUNTAINS AND VALLEYS OF LA/VTU COUNTIES. AFTER
COORDINATION WITH LOCAL AGENCIES IN SAN LUIS OBISPO AND SANTA BARBARA
COUNTIES...HAVE UPGRADED FIRE WEATHER WATCH TO A RED FLAG WARNING FOR
PORTIONS OF THESE COUNTIES AS WELL. OFFSHORE WINDS WILL NOT BE QUITE
AS STRONG IN THESE AREAS...BUT CONSIDERING THE LONG DURATION LOW
HUMIDITIY VALUES AND CRITICALLY DRY FUELS HAS PROMPTED THIS RED FLAG
WARNING EXPANSION.

ANOTHER VERY WARM NIGHT EXPECTED IN AREAS EXPOSED TO NORTHEAST
WINDS...WITH OVERNIGHT LOWS REMAINING IN THE LOWER TO MID 70S IN THESE
AREAS. WITH A CONTINUATION OF OFFSHORE WINDS AND EVEN A SLIGHTLY
WARMER AIR MASS ON THURSDAY...LOOK FOR MANY AREAS OF THE FORECAST AREA
TO WARM AN ADDITIONAL FEW DEGREES. THE ONLY EXCEPTION TO THIS MAY BE
THE IMMEDIATE COAST...WHICH WILL LIKELY BE THE SAME AS TODAY.
OFFSHORE WINDS ARE EXPECTED TO DIMINISH CONSIDERABLY BY THURSDAY
AFTERNOON AS OFFSORE PRESSURE GRADIENT BEGINS TO RELAX. A WEAK ONSHORE
FLOW PATTERN RETURNS TO THE AREA ON FRIDAY AS AN UPPER LEVEL TROUGH
MOVES INTO NORTHERN CALIFORNIA. THIS WILL BRING SOME COOLING AND A
GRADUAL INCREASE IN HUMIDITY VALUES ON FRIDAY...ESCPECIALLY NEAR THE
COAST. MORE SIGNIFICANT COOLING AND HUMIDITY RISES ARE EXPECTED ON
SATURDAY AS THE UPPER TROUGH DEEPENS ALONG THE CALIFORNIA COAST.
THE GFS AND NAM CONTINUE TO DISAGREE ON THE MAGNITUDE OF THIS TROUGH
FOR SATURDAY...WITH THE GFS CONTINUING TO BE THE MORE AGREESIVE MODEL.

*** LONG TERM FROM PREVIOUS DISCUSSION ***

.LONG TERM...A TROF WILL PASS THROUGH THE AREA SATURDAY, BRINGING A
BRIEF RETURN OF THE MARINE LYR AND COOLER DAYTIME TEMPS. INCREASING
NORTHWEST FLOW BEHIND IT WILL CREATE GUSTY NORTHWEST WINDS ALONG THE
CENTRAL COAST AND IN SRN SBA COUNTY SATURDAY AFTERNOON THROUGH
SUNDAY MORNING. THEN AS HIGH PRESSURE BUILDS BEHIND THE TROF SUNDAY
NIGHT INTO MONDAY, OFFSHORE FLOW WILL RETURN TO VENTURA AND LOS
ANGELES COUNTIES, POSSIBLY REQUIRING ANOTHER ROUND OF WIND
ADVISORIES. THE OFFSHORE FLOW WILL ALSO ALLOW DAYTIME TEMPS TO
REBOUND AT LOWER ELEVATIONS, THOUGH PRETTY STRONG COLD AIR ADVECTION
WILL PREVENT IT FROM GETTING AS WARM AS TODAY.

&&

.AVIATION...MAIN PROBLEM CONTINUES TO BE THE SANTA ANA WIND
EVENT. GUSTY NORTHEAST WINDS WILL CONTINUE BELOW AND THROUGH PASSES
AND CANYONS...POSING A LOW LEVEL WIND SHEAR THREAT...ESPECIALLY
NEAR KBUR TONIGHT AND THURSDAY MORNING. LIGHT NORTHEAST WINDS ARE
EXPECTED AT KLAX AND KLGB DURING THE LATE NIGHT AND MORNING HOURS...
THEN A MORE TYPICAL SEABREEZE EXPECTED ON THURSDAY AFTERNOON.

.LOX WATCHES/WARNINGS/ADVISORIES...
RED FLAG WARNING (SEE LAXRFWLOX).
FIRE WEATHER WATCH (SEE LAXRFWLOX).
