NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
300 AM PST MON DEC 14 2015

.SYNOPSIS...

IT WILL BE MOSTLY SUNNY COOL AND BREEZY TODAY...EXCEPT ON THE NORTH
SLOPES WHERE IT WILL BE MOSTLY CLOUDY WITH A CHANCE OF SHOWERS.
CONTINUED BREEZY WITH MOSTLY CLEAR SKIES THROUGH FRIDAY WITH A
WARMING TREND. CLOUDIER AND COOLER SATURDAY LEADING TO A CHANCE OF
RAIN ON SUNDAY.

&&

.SHORT TERM (TODAY-THU)... LARGE TROF OVER NEVADA IS MOVING EASTWARD
AND THE SFC COLD FRONT ASSOCIATED WITH IT IS MOVING INTO IMPERIAL
COUNTY. MOSTLY CLEAR SKIES OVER THE FORECAST AREA SAVE FOR THE NORTH
SLOPES WHERE NORTH FLOW IS PILING UP CLOUDS AND CREATING A CHANCE
FOR SHOWERS. SNOW LEVEL HAS DROPPED TO NEAR 3000 FEET AND TRAVELERS
ON I-5 MAY SEE SOME FLURRIES. WEAK PVA EMBEDDED IN THE FLOW AROUND
THE BACK SIDE OF THE LOW IS KEEPING SCATTERED SHOWER ACTIVITY GOING
IN THE OUTER WATERS. IT IS NOT INCONCEIVABLE THAT ONE OF THESE
SHOWERS MAY BRIEFLY MOVE OVER THE CENTRAL COAST. WINDS HAVE NOT
LIVED UP TO EXPECTATIONS AND WIND WARNINGS AND ADVISORIES ARE SORT
OF LIMPING ALONG AT THE MOMENT. MDLS STILL SHOW LOTS OF WIND AND
BELIEVE WINDS WILL PICK UP AFTER SUNRISE WHEN THE SUNSHINE HELPS MIX
THE WINDS DOWN. DID DOWNGRADE THE SBA COUNTY WARNINGS TO ADVISORIES
AS THERE IS NOT ENOUGH SUPPORT FOR 60+ MPH GUSTS ANYMORE. IT WILL BE
A COOL DAY WITH MOST MAX TEMPS ACROSS THE CSTS AND VLYS WITHIN A
DEGREE OR 2 OF 60.

FROM TUESDAY THROUGH THURSDAY THE UPPER FLOW WILL BE FAIRLY STRONG
AND FROM THE NORTH BY THURSDAY A EAST PAC RIDGE BUILDS IN AND THE
FLOW TURNS MORE THE NW. AT THE SFC HIGH PRESSURE BUILD INTO OREGON
ON TUESDAY SETTING UP NORTH FLOW...BY TUESDAY THE HIGH WILL MOVE
INTO NEVADA AND NE LOW LEVEL FLOW WILL SET UP...ON THURSDAY THE HIGH
AND NE FLOW WEAKENS. IT WILL BE BREEZY IN PLACES BOTH TUESDAY AND
WEDNESDAY MORNING. THE NORTHERLY CANYONS WILL LIGHT UP TUESDAY AND
THEN THE NORTHEAST CANYONS WILL HAVE THEIR TURN WEDNESDAY. THERE
WILL BE SOME PUFFS OF WINDS THU BUT NOTHING TOO SPECIAL. THERE MAY
BE A NEED FOR A FEW WIND ADVISORIES ON BOTH DAYS. ASIDE FROM THE
BREEZY AREAS OVERNIGHT LOWS WILL BE QUITE COOL. THE COLD AIRMASS
WILL COMBINE WITH THE CLEAR SKIES THE DRY AIR AND THE LONG NIGHTS TO
PRODUCE SOME VERY COOL TEMPS ACROSS THE AREA. WEDNESDAY MORNING WILL
BE THE COOLEST OF THEM ALL WITH ALMOST ALL OF SLO AND SBA COUNTIES
AT OR BELOW FREEZING. AS FOR LA AND VTA COUNTY ONLY THE URBAN HEAT
ISLAND OF LOS ANGELES WILL STAY ABOVE 40 DEGREES WITH NEAR FREEZING
TEMPS IN THE VLYS EITHER SIDE OF THE VTA/LA COUNTY LINE.

DURING THE DAYTIME HOURS SKIES WILL BE MOSTLY SUNNY AND THERE WILL
BE SLOW WARMING TREND WITH MAX TEMPS APPROACHING NORMALS BY THURSDAY.

.LONG TERM (FRI-SUN)... THE RIDGE WILL SIT DIRECTLY ATOP THE STATE
ON FRIDAY. WEAK OFFSHORE FLOW WILL PERSIST OVER SRN CA. THE
COMBINATION OF THESE TWO ITEMS WILL MAKE FRIDAY THE WARMEST DAY WITH
MAX TEMPS A COUPLE OF DEGREES ABOVE NORMAL.

THE RIDGE MOVES OFF TO THE EAST ON SATURDAY AS A TROF BEGINS TO MOVE
CLOSER TO THE STATE FROM THE WEST. SKIES WILL TURN PARTLY CLOUDY.
HGTS WILL ALSO FALL AND THE SFC FLOW WILL REVERSE TO ONSHORE. ALL OF
THIS WILL KNOCK SEVERAL DEGREES OFF OF THE MAX TEMPS.

ALL MDLS ROLE A TROF OVER THE AREA SUNDAY...BUT NONE OF THEM AGREE
ON THE DETAILS. THE EC AND GFS BRING SOME RAIN TO THE AREA EARLY
SUNDAY. THE GFS MORESO BECAUSE IT KEEP THE LOW CLOSER TO THE
FORECAST AREA. THE EC CONTINUES ITS THINKING OF KEEPING THE UPPER
LOW FURTHER OFF THE COAST. THE UK MDL BRING NOW RAIN TO THE AREA AS
IT KEEPS THE LOW WELL OFF THE COAST. FOR NOW JUST BROAD BRUSHED
CLOUDS AND CHC POPS INTO THE SUNDAY FORECAST AND WILL PLAY THE WAIT
AND SEE GAME.

ALL MDLS KEEP THE AREA IN THE WETTER PATTERN FOR EARLY NEXT WEEK.
