SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
400 PM PST SUN DEC 29 2013

CORRECTED TIME IN AVIATION SECTION

.SYNOPSIS...
GUSTY SANTA ANA WINDS WILL WEAKEN TONIGHT BUT REMAIN LOCALLY GUSTY
INTO MONDAY. CRITICAL FIRE WEATHER CONDITIONS WILL CONTINUE INTO
MONDAY AS A RESULT. ABOVE SEASONAL TEMPERATURES WILL PERSIST THROUGH
THE WEEK WITH DRY CONDITIONS AND LIGHT OFFSHORE FLOW. ANOTHER SANTA
ANA MAY FORM BY THE END OF THE WEEK.

&&

.SHORT TERM (TODAY-THURSDAY)...
THE SANTA WINDS ARE IN FULL EFFECT AT THIS MOMENT...IMPACTING MOST
OF LOS ANGELES AND VENTURA COUNTIES. THE WINDS IN THE MOUNTAINS ARE
STARTING TO WEAKEN AS OFFSHORE GRADIENTS AND UPPER LEVEL WINDS
PEAKED ABOUT 3 HOURS AGO. CURRENT SUITE OF WIND WARNING AND
ADVISORIES WILL LIKELY NEED SOME MODIFICATIONS OVER THE NEXT COUPLE
OF HOURS...WITH THE DOWNGRADING OF THE WARNINGS TO AN ADVISORY MOST
LIKELY TO HAPPEN SOON. TEMPERATURES ARE UP 10-15 DEGREES ABOVE
NORMAL OVER THE COASTAL AND VALLEY SECTIONS THANKS TO THE OFFSHORE
FLOW...WITH INTERIOR AREAS VERY CLOSE TO NORMAL.

THE WINDS WILL WEAKEN TONIGHT INTO MONDAY...AND WHILE THEY WILL
REMAIN GUSTY IN THE MOUNTAINS AND VALLEYS...IT NOW LOOKS TO BE
SUB-ADVISORY...ESPECIALLY BY MIDNIGHT TONIGHT. TEMPERATURES ARE
STILL ON TRACK TO BUMP UP TOMORROW...MOST FELT OVER THE INTERIOR
AREAS...BUT EXPECTING A FEW MORE VALLEY LOCATIONS HITTING THE 80
MARK. SOME COASTAL AREAS HOWEVER SHOULD COOL WITH THE LACK OF
OFFSHORE FLOW HITTING DOWN THE COAST. NOT EXPECTING ANY FOG TONIGHT.
OVERNIGHT TEMPERATURE WILL BE CHILLY WITH THE VERY DRY
AIR...ESPECIALLY INTERIOR AREAS WHERE LOWS WILL DROP INTO THE 20S.

VERY LITTLE CHANGE TUESDAY THROUGH THURSDAY...WITH ABOVE NORMAL
TEMPERATURES AND DRY OFFSHORE FLOW. THERE ARE TWO WRINKLES TO THIS
SIMPLISTIC DESCRIPTION. FIRST OFF...A SMATTERING OF HIGH CLOUDS
SHOULD STREAM OVER THE AREA STARTING ON TUESDAY. SECONDLY...THE NAM
IS SHOWING A SLIGHT BOOST TO THE WEAK OFFSHORE GRADIENTS ON
WEDNESDAY AND THURSDAY. THIS BOOST WOULD BRING SOME GUSTIER WINDS TO
THE AREA...BUT NOTHING CLOSE TO ADVISORY...AS WELL AS SOME WARMING
TO THE COASTAL SIDE OF THINGS.

.LONG TERM (FRIDAY-SUNDAY)...
WHILE THERE STILL IS PLENTY TO NOT BE CONFIDENT ABOUT IN THE
EXTENDED...AS QUANTIFIED BY THE 10DM STANDARD DEVIATION SPREAD IN
THE ENSEMBLES BY THE WEEKEND...IT SEEMS LIKE MOST SOLUTIONS ARE
CONVERGING TOWARD AN INSIDE SLIDER DROPPING THROUGH UTAH ON FRIDAY
OR SATURDAY. THIS PATTERN WOULD SET UP ANOTHER MODERATE-LOOKING
SANTA ANA EVENT OVER THE WEEKEND. TRENDED FORECAST TOWARD THIS
SCENARIO...BUT THIS IS STILL A WAYS OUT WITH PLENTY REASON TO WRITE
THIS PART OF THE FORECAST IN ERASABLE INK.

&&

.AVIATION...30/0000Z.

VFR CONDITIONS ARE EXPECTED THROUGHOUT THE PERIOD. PERIODS OF
MODERATE TO STRONG LOW-LEVEL WIND SHEAR AND TURBULENCE WILL LIKELY
OCCUR AT COASTAL AND VALLEY TERMINALS SOUTH OF POINT CONCEPTION
THROUGH 08Z TONIGHT.

KLAX...VFR CONDITIONS ARE EXPECTED THROUGHOUT THE PERIOD. THERE IS A
30 PERCENT OF OCCASIONAL MODERATE LOW-LEVEL WIND SHEAR AND
TURBULENCE THROUGH 04Z.

KBUR...VFR CONDITIONS ARE EXPECTED THROUGHOUT THE PERIOD. PERIODS OF
MODERATE LOW-LEVEL WIND SHEAR AND TURBULENCE WILL LIKELY OCCUR
THROUGH 08Z.

&&

.FIRE WEATHER...29/2200Z
THE COMBINATION OF MODERATE TO STRONG NORTHEAST WINDS...LOW
HUMIDITIES...WARM TEMPERATURES...AND DRY FUELS IS BRINGING CRITICAL
FIRE WEATHER CONDITIONS TO MUCH OF LOS ANGELES AND VENTURA COUNTIES
TODAY...PROMPTING THE THE RED FLAG WARNING. LIGHTER OFFSHORE WINDS
AND LOW HUMIDITIES WILL IMPACT PORTIONS OF SLO/SBA COUNTIES
TODAY...BRINGING ELEVATED FIRE DANGER TO THOSE AREAS. OFFSHORE WINDS
ARE EXPECTED TO GRADUALLY WEAKEN TONIGHT INTO MONDAY...HOWEVER VERY
WARM AND DRY CONDITIONS WILL CONTINUE INTO MONDAY. VERY POOR
HUMIDITY RECOVERIES ARE EXPECTED TONIGHT WITH MANY
FOOTHILL...MOUNTAIN...AND WIND EXPOSED LOCATIONS REMAINING BELOW 15
PERCENT. WIDESPREAD SINGLE DIGIT HUMIDITY READINGS ARE THEN EXPECTED
ON MONDAY DUE TO THE CONTINUED OFFSHORE INFLUENCE. RED FLAG WARNINGS
HAVE BEEN EXTENDED INTO MONDAY MORNING TO ACCOUNT FOR THIS.
