SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
932 AM PDT SUN JUL 8 2012

.SYNOPSIS...

A WARMING TREND WILL CONTINUE THROUGH MIDWEEK AS HIGH PRESSURE
EXPANDS WEST OVER THE REGION. NIGHT THROUGH MORNING LOW CLOUDS
AND FOG WILL REMAIN CONFINED MOSTLY TO THE COAST THROUGH MUCH OF
THE WEEK. MOISTURE EMBEDDED IN A DEVELOPING SOUTHEAST FLOW ALOFT
ON TUESDAY MAY BRING SHOWERS AND THUNDERSTORMS FOR THE SOUTHERN
MOUNTAINS AND DESERT BETWEEN TUESDAY AND FRIDAY. COOLING IS
POSSIBLE BY THE END OF THE WEEK AS HIGH PRESSURE MAY SHIFT EAST.

&&

.UPDATE...

MARINE LAYER STRATUS IS BURNING OFF MORE QUICKLY TODAY VERSUS
YESTERDAY...ESPECIALLY SOUTH OF POINT CONCEPTION. MARINE LAYER
DEPTH...SLIGHTLY THINNER THAN YESTERDAY...IS NEAR 1100 FEET AT
KLAX AND SLOPING UPWARD TO NEAR 1700 FEET NORTH OF POINT
CONCEPTION. A SHRINKING MARINE LAYER AND A WARMING TREND WILL
PERSIST THROUGH MIDWEEK AS AN UPPER-LEVEL RIDGE CONTINUES TO
BUILD WEST OVER THE REGION. MARINE LAYER STRATUS WILL LIKELY TO
BE CONFINED TO THE COASTAL PLAIN TONIGHT AND INTO MONDAY
MORNING...WITH PATCHY DENSE FOG ACROSS PORTIONS OF THE COASTAL
PLAIN. THE FORECAST PACKAGE IS IN REASONABLY GOOD SHAPE AND NO
ADDITIONAL UPDATES ARE PLANNED.

&&

.PREV DISCUSSION...

SHORT TERM...ADDITIONAL WARMING WILL OCCUR BOTH MON AND
TUE...WITH SOME LOCATIONS IN THE ANTELOPE VALLEY REACHING OR
EXCEEDING 105 DEGREES BY TUE. WARMER VALLEY LOCATIONS W OF THE
MOUNTAINS WILL LIKELY HAVE HIGH TEMPERATURES NEAR OR A FEW DEGREES
ABOVE 100 DEGREES BY TUE...WITH A FEW LOCATIONS POSSIBLY REACHING
100 DEGREES AS EARLY AS MONDAY AFTERNOON. THE MID AND UPPER LEVEL
FLOW WILL BEGIN TO TURN MORE SELY MONDAY...BUT CONDS THROUGHOUT
THE ATMOSPHERE LOOK VERY DRY. THERE WILL PROBABLY BE SOME BUILDUPS
IN THE MTNS OF L.A. COUNTY MON...BUT A THIS POINT...DO NOT EXPECT
ANY SHOWERS/TSTMS. ON TUE...MODELS SHOW A BIT MORE IN THE WAY OF
MOISTURE...SO THE SLIGHT CHANCE OF SHOWERS/TSTMS LOOKS GOOD IN THE
MTNS OF L.A. AND VTU COUNTIES AND THE ANTELOPE VALLEY.

LONG TERM...THERE WILL BE LITTLE CHANGE IN THE UPPER PATTERN WED
THROUGH FRI...ALTHOUGH THE UPPER HIGH WILL BEGIN TO WEAKEN
SLIGHTLY AND SHIFT EWD. MODELS CONTINUE TO DIFFER WITH RESPECT TO
THE AMOUNT OF MOISTURE PUSHING INTO THE AREA...AS WELL AS WITH THE
TIMING OF THE BEST MOISTURE. HOWEVER...IT LOOKS AS THOUGH THE
THREAT OF AFTERNOON AND EVENING SHOWERS/TSTMS WILL CONT IN THE
MTNS OF L.A. AND VTU COUNTIES AND THE ANTELOPE VALLEY WED THRU
FRI...WITH SOME TSTMS POSSIBLY SLIPPING INTO THE MTNS OF SBA
COUNTY AS WELL. CONDS APPEAR TO BE MOST FAVORABLE FOR CONVECTION
ON THU. TEMPS ON WED WILL BE VERY SIMILAR TO THOSE ON TUE...THEN
THERE MAY BE SOME SLIGHT COOLING THU THROUGH SAT. HOWEVER...THE
00Z AND 06Z RUNS OF THE GFS WOULD SUGGEST LESS IN THE WAY OF
COOLING AS THE HIGH DOES NOT WEAKEN AND SHIFT EWD AS MUCH. EITHER
WAY...TEMPS WILL BE ABOVE NORMAL IN MOST AREAS WED AND THU...AND
PROBABLY FRI AS WELL. THE ECMWF IS MORE AGGRESSIVE WITH A TROUGH
MOVING INTO THE W COAST LATE FRI AND SAT...BUT BOTH THE ECMWF AND
THE GFS INDICATE LITTLE CHANCE OF TSTMS ON SAT AS THE UPPER FLOW
TURNS MORE SWLY.

.AVIATION...08/1125Z.

MARINE LAYER AT 1000 FEET AND CLOUDS WITH IFR CIGS COVER THE COASTS
AND MOST OF THE VALLEYS. PRETTY GOOD CONFIDENCE IN BURN OFF TIMES
TODAY AND THEY WILL ALL LIKELY COME IN WITHIN AN HOUR OF FCST. LESS
CONFIDENCE IN CLOUDS RETURN TIMES TONIGHT. THE VLYS WILL LIKELY
REMAIN CLEAR.

KLAX...GOOD CONFIDENCE IN TAF CLOUDS COULD BURN OFF +/- 1 HOUR FROM
FCST. LESS CONFIDENCE ON CLOUD RETURN TONIGHT AND CIGS COULD BE
DELAYED UNTIL 10Z.

KBUR...FAIR CONFIDENCE IN TAF WITH A 30 PERCENT CHC OF BURN OFF AT
15Z. GOOD CONFIDENCE IN VFR FCST TONIGHT.

&&

.FIRE WEATHER...

WARMING AND DRYING TREND TODAY THROUGH MONDAY. SEVERAL AUTOMATED
STATIONS REPORTING SINGLE DIGIT HUMIDITIES SATURDAY AFTERNOON ACROSS
THE MOUNTAINS AND ANTELOPE VALLEY. SINGLE DIGIT HUMIDITIES EXPECTED
TO BE EVEN MORE WIDESPREAD AND FOR LONGER DURATION TODAY...LIKELY
SPREADING INTO SOME OF THE FOOTHILL AREAS AND SANTA CLARITA VALLEY.
IN ADDITION...VERY POOR HUMIDITY RECOVERIES EXPECTED ACROSS THE
MOUNTAINS TONIGHT...WITH SOME STATIONS IN THE LOS ANGELES
COUNTY MOUNTAINS REMAINING IN SINGLE DIGITS THROUGH MUCH OF THE
NIGHT. CONTINUED VERY DRY ACROSS SAME AREAS INTO MONDAY.
TEMPERATURES WILL CLIMB WELL INTO THE 90S ACROSS INTERIOR SECTIONS
OVER THE WEEKEND...WITH TRIPLE DIGIT READINGS ACROSS THE ANTELOPE
VALLEY. BY MONDAY...TRIPLE DIGIT HEAT IS EXPECTED TO EXPAND INTO
SOME OF THE MOUNTAIN AND INTERIOR VALLEY LOCATIONS. THIS WARMING AND
DRYING TREND WILL BRING HEIGHTENED FIRE WEATHER CONCERNS TO THE
MOUNTAINS AND DESERTS TODAY THROUGH MONDAY. OF GREATEST CONCERN WILL
BE DURING THE AFTERNOON AND EVENING HOURS WHEN GUSTY ONSHORE WINDS
COMBINE WITH LOW HUMIDITIES TO PRODUCE A PERIOD OF CRITICAL FIRE
WEATHER CONDITIONS. AT THIS TIME...IT APPEARS THAT SUNDAY WILL HAVE
THE LONGEST DURATION OF CRITICAL FIRE WEATHER CONDITIONS...WITH THE
LOS ANGELES COUNTY MOUNTAINS AND ADJACENT FOOTHILLS LIKELY HAVING
DURATIONS APPROACHING CRITICAL RED FLAG THRESHOLDS. TUESDAY THROUGH
FRIDAY...UPPER LEVEL PATTERN BECOMES MORE FAVORABLE FOR SOME
MONSOONAL MOISTURE TO STREAM INTO REGION...PROMPTING A SLIGHT CHANCE
OF AFTERNOON AND EVENING THUNDERSTORMS ACROSS OUR LOCAL MOUNTAINS
AND ANTELOPE VALLEY.  INITIALLY...MOISTURE APPEARS TO BE CONFINED TO
THE MID LEVELS...WITH THE LOWER LEVELS REMAINING QUITE DRY. AS A
RESULT...WILL HAVE POTENTIAL FOR DRY LIGHTNING AND GUSTY DOWNDRAFT
WINDS IF ANY STORMS DEVELOP ON TUESDAY. CROSS SECTIONS INDICATING
DEEPER MOISTURE BY WEDNESDAY WITH A BETTER POSSIBILITY OF WETTING
STORMS.
