SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
940 PM PST THU DEC 19 2013

AVIATION DISCUSSION UPDATED

.SYNOPSIS...

RAIN SHOWERS AND MOUNTAIN SNOW MAY CONTINUE OVERNIGHT...MAINLY IN
LOS ANGELES COUNTY...ALONG WITH COLD OVERNIGHT TEMPERATURES MOST
EVERYWHERE. HIGH PRESSURE AND OFFSHORE WINDS WILL BRING A GRADUAL
WARMING TREND TO THE AREA...BEGINNING FRIDAY AFTERNOON THROUGH THE
MIDDLE OF NEXT WEEK.

&&

.SHORT TERM (TONIGHT-SUN)...

HIGH TEMPS WERE A GOOD 15-20 DEGREES COOLER IN SEVERAL PARTS OF THE
FORECAST AREA AS EXPECTED COMPARED TO YESTERDAY. TODAYS HIGHS FOR
COAST AND VALLEYS WERE MAINLY IN THE MID TO UPPER 50S WITH MUCH
COLDER TEMPS FOR THE MOUNTAINS. PALMDALE/LANCASTER REACHED THE LOWER
50S AS WELL TODAY. THERE WERE HEAVY SNOW SHOWERS OCCURRING AROUND
THE MOUNT HIGH AREA EARLIER THIS EVE. HAVE NOT RECEIVED ANY UPDATE
INFO ON SNOW AMOUNTS...BUT THERE WAS AT LEAST A FEW INCHES THAT FELL
THIS EVENING BASED ON RADAR ESTIMATES.

SHOWERS AND SNOW SHOWERS HAVE DISSIPATED ACROSS MOST OF THE FORECAST
AREA EXCEPT FOR LA COUNTY THIS EVENING. EXPECT WRAP-AROUND SCATTERED
SHOWERS AND SNOW SHOWERS FOR THE LA COUNTY MOUNTAINS...OTHERWISE
ISOLATED SHOWERS WILL CONTINUE FOR THE REST OF LA COUNTY THROUGH
MIDNIGHT BEFORE EXITING THE AREA. THERE WILL BE SOME LINGERING LOW
LEVEL MOISTURE ACROSS THE SAN GABRIEL MOUNTAINS AND THE NORTHERN
SLOPES OF THE VENTURA COUNTY MOUNTAINS NEAR THE I-5 CORRIDOR THAT
COULD BE AFFECTED WITH A FEW RAIN AND SNOW SHOWERS LATE TONIGHT INTO
EARLY FRIDAY MORNING. WINDS HAVE CALMED DOWN AS WELL ACROSS MOST OF
THE FORECAST AREA. SNOW LEVELS WERE DOWN TO AROUND 4500 FT THIS
EVE...BUT SHOULD LOWER TO AROUND 3500 FT OVERNIGHT. BUT BY
THEN...MOST OF THE SHOWERS WILL BE WELL EAST AND SOUTH OF THE AREA.
A WINTER WEATHER ADVISORY REMAINS IN EFFECT UNTIL 4 AM THIS
MORNING...BUT WOULD NOT BE SURPRISED IF THE MID SHIFT DECIDED TO
CANCEL THIS AS MOISTURE SHOULD BE MOVING TO THE EAST AND SOUTH.

THE UPPER LOW THAT MOVED ACROSS SO CAL BIGHT EARLIER TODAY WAS NOW
OFF THE COAST OF NORTHERN BAJA AND WILL CONTINUE TO MOVE INTO
NORTHERN MEXICO BY TOMORROW AFTERNOON. BEHIND THE EXITING
LOW...ANOTHER STRONG ELONGATED CUTOFF HIGH WILL DEVELOP OFF THE WEST
COAST AS WE HAVE SEEN OVER THE PAST MONTH. THIS WILL ALLOW FOR A
STRONG MERIDIONAL FLOW BRINGING N TO NW COOL CANADIAN AIR DOWN INTO
THE WESTERN STATES ONCE AGAIN. (NOT NEARLY AS COLD AS THE MODIFIED
ARCTIC AIR MASS WE EXPERIENCED A FEW WEEKS AGO). THIS BROAD N TO NW
FLOW ALOFT WILL HELP KEEP HIGH TEMPS IN THE 60S TO LOWER 70S THROUGH
MUCH OF NEXT WEEK.

AT THE LOWER LEVELS...WEAK OFFSHORE FLOW WILL BUILD IN BEHIND THE
EXITING FRONT TOMORROW. HIGH TEMPS WILL BE A GOOD 6 TO 10 DEGREES
WARMER WITH MOST COAST AND VALLEYS REACHING THE LOWER TO MID
60S...WHILE THE MOUNTAINS REMAIN QUITE COOL. THERE SHOULD BE SOME
LINGERING CLOUDS AROUND THE LA/VTU/SBA COUNTY MOUNTAINS TOMORROW AS
WELL. THERE COULD BE A FEW SNOW FLURRIES AROUND THE EASTERN SAN
GABRIEL MOUNTAINS AS WELL. AS FAR AS THE LOW TEMPS...EXPECT SUB
FREEZING TEMPS FOR THE ANTELOPE VALLEY AND INTERIOR SLO COUNTY
VALLEYS. THESE AREAS HAVE ALREADY ENCOUNTERED TWO HARD FREEZES THIS
FALL SO THERE WILL NOT BE ANY HARD-FREEZE WARNINGS ISSUED ANY LONGER
FOR THESE AREAS ANY LONGER THIS WINTER. NOT EXPECTING FREEZING
CONDITIONS FOR THE CENTRAL COAST OR SANTA YNEZ VALLEY OVER THE NEXT
FEW DAYS...BUT THERE COULD BE SOME FROST ISSUES FOR THE OJAI VALLEY
BOTH EARLY SAT/SUN MORNING.

FOR SATURDAY...EXPECT A CRISP COOL DAY WITH MOSTLY SUNNY SKIES. HIGH
TEMPS WILL REACH THE LOWER TO MID 60S WITH WEAK OFFSHORE FLOW ACROSS
THE INLAND AREAS.

THE NAM-WRF IS ADVERTISING A RELATIVELY WEAK CATALINA EDDY TO
DEVELOP LATE FRIDAY NIGHT INTO SAT MORNING. ALTHOUGH 850 TEMPS ARE
QUITE COOL WHICH SHOULD HINDER ANY DEEP MARINE LAYER DEVELOPMENT
CROSS SECTIONS ARE INDICATING SOME LOW CLOUDS DEVELOPING OFF THE SO
CAL COAST AND PUSHING INTO THE LA/VTU COAST EARLY SATURDAY MORNING.
SO HAVE ADDED SOME PATCHY LOW CLOUDS TO THE FORECAST FOR SAT AND SUN
MORNINGS FOR LA/VTU COAST AND UP TO SBA COAST FOR SUNDAY MORNING.

THERE SHOULD BE BETTER WARMING FOR COAST AND COASTAL VALLEYS AS THE
OFFSHORE PRESSURE GRADIENTS STRENGTHEN. THIS WILL BRING SOME GUSTY
WINDS TO THE USUAL WIND PRONE AREAS OF LOS ANGELES AND VENTURA
COUNTIES SUNDAY MORNING...BUT IT MIGHT TAKE A FEW HOURS TO SCOUR OUT
ANY STRATUS THAT DEVELOPS ALONG THE COAST. HIGH TEMPS SHOULD REACH
THE LOWER 70S ON SUNDAY WHICH WOULD BE A BIT WARMER THAN NORMAL FOR
THIS TIME OF YEAR. AT THIS TIME...WIND GUSTS LOOK TO BE BELOW WIND
ADVISORY THRESHOLDS...BUT WOULD NOT BE SURPRISED TO SEE SOME COLD
AIR ADVECTION PUSH INTO THE HIGH DESERT TO HELP STRENGTHEN THE
WINDS.

***FROM PREVIOUS DISCUSSION***

.LONG TERM (MON-THU)...

HIGH PRESSURE AND OFFSHORE FLOW WILL DRIVE THE WEATHER CONDITIONS
NEXT WEEK. LOW HUMIDITY AND WARM DAYTIME TEMPERATURES SHOULD BE
EXPECTED INTO AT LEAST BOXING DAY. THE WARMEST DAY OF THE WEEK
LOOKS TO TUESDAY. LOCALLY GUSTY WINDS COULD PERSIST INTO TUESDAY
THROUGH AND BELOW PASSES AND CANYONS...AND ANOTHER OFFSHORE BREEZY
DAY COULD BE IN THE WORKS FOR THURSDAY.

&&

.AVIATION...20/06Z.
MODERATE TO HIGH CONFIDENCE IN 06Z TAFS.  A FEW SPRINKLES ARE
POSSIBLE IN THE SERVICE AREA TONIGHT BUT IN GENERAL CONDITIONS ARE
IMPROVING AND BOTH CIGS AND VSBYS SHOULD BE VFR THROUGHOUT THE
FORECAST PERIOD.  A 10 PERCENT CHANCE AT BEST FOR BRIEF
PRECIPITATION AND MVFR CIGS THROUGH 08Z IN LOS ANGELES COUNTY.

KLAX...MODERATE TO HIGH CONFIDENCE IN 06Z TAF.  AT BEST A 10 PERCENT
CHANCE FOR BRIEF PRECIPITATION AND MVFR CIGS THROUGH 08Z BUT IN
GENERAL CONDITIONS ARE IMPROVING AND BOTH CIGS AND VSBYS SHOULD BE
