SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
850 AM PST TUE NOV 11 2014

.SYNOPSIS...

THE ONSHORE FLOW WILL BRING NIGHT THROUGH MORNING CLOUDS... DRIZZLE
AND FOG INTO WEDNESDAY. THERE WILL BE POSSIBLE PRECIPITATION FROM
LOMPOC AND NORTHWARD EARLY THURSDAY AS A COLD FRONT MOVES ACROSS.
HIGH PRESSURE WITH OFFSHORE FLOW WILL BRING CLEARING INTO THE
WEEKEND... BUT THE ARRIVAL OF AN LOW PRESSURE SYSTEM NEXT WEEK WILL
BRING THE POSSIBILITY OF PRECIPITATION TO THE CENTRAL COAST AGAIN ON
MONDAY.

&&

.SHORT TERM (TODAY-THU)...
...MID MORNING DISCUSSION UPDATE...
TEMPERATURES ARE RUNNING UP TO A FEW DEGREES WARMER AT COASTAL AND
VALLEY LOCATIONS AND UP TO SEVERAL DEGRESS COOLER IN THE MOUNTAINS
DUE TO THE DEEP MARINE INTRUSION THIS MORNING.  IT IS POSSIBLE THAT
CLEARING MAY BE REVERSED FROM THE NORM AND THAT THE COASTAL
LOCATIONS SEE HAZY SUNSHINE BEFORE THE MOUNTAIN AND INLAND VALLEYS
DO.  WHAT CLEARING DOES COME TODAY WILL BE DIMINISHED EARLY AS THE
INTRUSION RETURNS AGAIN EARLY TONIGHT AND THE CYCLE REPEATS
OVERNIGHT AND INTO TOMORROW.  AREAS OF DRIZZLE WERE REPORTED THIS
MORNING AND DRIZZLE CONTINUES TO BE EXPECTED AGAIN OVERNIGHT AND
TOMORROW MORNING.

PRIMARY FOCUS OF THE DAY WILL BE TO SHARPEN THE FORECAST FOR THE
FRONTAL PASSAGE ON WEDNESDAY NIGHT AND THURSDAY... AND AGAIN ON
MONDAY TUESDAY.  CURRENT PACKAGE BRINGS PRECIPITATION CHANCES TO SAN
LUIS OBISBO AND SANTA BARBARA COUNTIES WITH BOTH FRONTS AND IT IS
UNLIKELY TO SEE THAT FORECAST BE CHANGED AT THIS TIME.  TIMING ALSO
LOOKS GOOD... THE FORECAST PACKAGE IN GENERAL LOOKS GOOD... BUT WILL
BE REVIEWING IT FOR POSSIBLE TWEAKS.

...EARLY MORNING DISCUSSION...
TODAY AND WEDNESDAY WILL BE VERY SIMILAR AND VERY CLOUDY. A 4300
FOOT MARINE LAYER...A WEAK EDDY AND MODERATE ONSHORE FLOW BOTH TO
THE EAST AND NORTH WILL KEEP THE AREA MOSTLY CLOUDY SAVE FOR THE
DESERTS AND THE MOUNTAINS OVER 5000 FEET. CURRENT SATELLITE SHOW
MARINE LAYER STRATUS COVERING ALMOST ALL OF THE FORECAST AREA...IN
FACT I CANNOT NOT THINK OF A TIME WHERE THE MARINE CLOUD LAYER WAS
MORE EXTENSIVE. THERE SHOULD BE MINIMAL CLEARING THIS AFTERNOON AND
IF THERE IS ANY THE RESULTANT SFC HEATING WILL QUICKLY COOK UP A
STRATCU DECK. TOOL THE DRIZZLE OUT OF THE COASTAL SECTIONS OF THE
FCST AND REALLY DO NOT HAVE MUCH CONFIDENCE IN IT OCCURRING IN THE
VLYS BUT THERE IS A BETTER CHANCE THERE. THE BEST DRIZZLE CHANCES
WILL BE IN THE MOUNTAINS. MAX TEMPS WILL BE VERY MID 60S TO THE
LOWER 70S THROUGHOUT THE CSTS AND VLYS. WEDNESDAY SHOULD BE VERY
SIMILAR. THE ONE THING TO KEEP IN THE BACK OF ONES MIND IS THAT WHEN
THE MARINE LAYER GETS THIS DEEP SOMETIMES IT JUST MIXES OUT BY
ITSELF AND SKIES WILL TURN PARTLY CLOUDY. USUALLY THERE HAS TO BE A
LITTLE DISTURBANCE FOR THIS TO HAPPEN SO FEEL GOOD ABOUT THE CLOUDY
FCST FOR NEXT 48 HOURS.

ANOTHER DEEP MARINE CLOUD LAYER THURSDAY MORNING. THE WEAK RIDGE
WILL FLATTEN OUT AS A WEAK FRONT RIDES UP ITS BACKSIDE. THERE IS A
20 PERCENT CHANCE THIS FRONT WILL BRING SOME RAIN TO THE CENTRAL
COAST BUT MORE THAN LIKELY IT WILL JUST BRING CLOUDS. THE GOOD THING
IS THAT THE FRONT SHOULD MIX OUT THE MARINE INVERSION AND THE
AFTERNOON SHOULD BE SUNNIER. MAX TEMPS WILL NOT CHANGE MUCH FROM
TODAY OR WED.

.LONG TERM (FRI-MON)...
RIDGING AND OFFSHORE FLOW SET UP FRIDAY THROUGH SUNDAY. MAX TEMPS
WILL WARM EACH DAY. BOTH SATURDAY AND SUNDAY SHOULD SPORT ABOVE
NORMAL MAX TEMPS WITH SUNDAY THE WARMEST. NORTH WINDS WILL SET UP
FRIDAY WITH A GOOD SUNDOWNER AND SOME I-5 CORRIDOR WINDS. SUB
ADVISORY NE WINDS WILL OCCUR SAT AND SUNDAY MORNING BELOW PASSES AND
CANYONS.

THERE IS ZERO AGREEMENT OF ALL OF THE LONG RANGE MDLS FOR MONDAY.
THE EC HAS BEEN CONSISTENTLY WET FOR MONDAY SO ADDED A 20 PERCENT
CHANCE OF RAIN FOR SLO AND SBA COUNTIES BUT THE GFS AND CANADIAN
MDLS DO NOT AGREE. SO IT COULD BE CLOUDY AND COOL WITH RAIN OR SUNNY
AND WARM WITH A LITTLE MARINE LAYER CLOUDY DECK DEPENDING ON WHAT
MDL ONE WANTS TO BELIEVE.

IT LOOKS LIKE A PATTERN CHANGE IS TRYING TO SET UP AND THE MDLS JUST
CANNOT HANDLE IT. IT LOOKS LIKE THERE WILL BE A PRETTY GOOD CHANCE
OF RAIN ONE DAY NEXT WEEK JUST CANNOT SAY WHAT DAY RIGHT NOW.
