SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
1230 PM PDT SUN JUN 16 2013

...NEW AVIATION/MARINE DISCUSSIONS...

.SYNOPSIS...

SOUTHWEST FLOW ALOFT OVER SOUTHERN CALIFORNIA WILL CONTINUE
ONSHORE FLOW AND NIGHT THROUGH MORNING LOW CLOUDS NEAR THE COAST
THROUGH EARLY WEEK. A NORTHERLY SURFACE PRESSURE DIFFERENCE
ACROSS THE STATE WILL WEAKEN ONSHORE FLOW BETWEEN MONDAY AND
WEDNESDAY...AND BRING BREEZY TO WINDY CONDITIONS TO SOUTHERN SANTA
BARBARA COUNTY AND THROUGH THE INTERSTATE 5 CORRIDOR. A WARMING
TREND IS POSSIBLE FROM LATE THIS WEEK THROUGH NEXT WEEKEND.

&&

.UPDATE...

THE LATEST SATELLITE IMAGERY INDICATES THE MARINE LAYER STRATUS
STARTING TO BURN OFF OVER THE VALLEY AREAS THIS MORNING. 12Z KNKX
AND KVBG SOUNDINGS INDICATE A STRENGTHENING MARINE INVERSION AS
THE AIR MASS WARMS BETWEEN 900 AND 950 MB. THERE IS SOME CONCERN
THIS MORNING THAT THE BEACHES...ESPECIALLY SOUTH OF POINT
CONCEPTION...MAY STRUGGLE TO CLEAR THIS AFTERNOON. AT LEAST...A
LITTLE LATER CLEARING SHOULD OCCUR AT THE BEACHES TODAY VERSUS
YESTERDAY. THE CURRENT PACKAGE LOOKS A LITTLE TOO OPTIMISTIC WITH
CLEARING AND THE PACKAGE WILL BE NUDGED TOWARD A MORE GLOOMY JUNE-
LIKE PATTERN AT THE BEACHES.

WITH THE WARMING TAKING PLACE BETWEEN 900 MB AND 950 MB...THE
HIGH VALLEYS...MOUNTAINS...AND DESERT SHOULD WARM A BIT OVER
YESTERDAY. WITH THE MARINE LAYER DEPTH NEAR 2300 FEET...SOME
TWEAKS WILL BE MADE NEAR THE MARINE LAYER TOP AND ABOVE THE
MARINE LAYER FOR TEMPERATURES FOR TODAY.

MAIN CONCERN FOR THE PACKAGE WILL BE THE NORTHERLY SURFACE
PRESSURE GRADIENTS DEVELOPING OVER THE NEXT SEVERAL DAYS. AT
LEAST...LOCALIZED SUNDOWNER AND I-5 CORRIDOR WINDS REACHING
ADVISORY LEVEL WINDS WILL OCCUR TONIGHT AND INTO MONDAY
MORNING. THERE IS A CHANCE THAT THESE WINDS COULD BECOME MORE
WIDESPREAD THAT WHAT THE CURRENT PACKAGE INDICATES. THE 850 MB
THERMAL PATTERN LOOKS MORE FAVORABLE FOR SUNDOWNER WINDS AND WINDS
THROUGH INTERSTATE 5 CORRIDOR BETWEEN MONDAY AND WEDNESDAY WITH
THE WIND REGIMES BECOMING MORE PRONOUNCED EACH AFTERNOON AND
NIGHT BETWEEN MONDAY AND WEDNESDAY MORNING.

&&

.PREV DISCUSSION...

SHORT TERM...SORT OF A DO OVER MON NIGHT AND TUESDAY. GUSTY
NORTHERLY WINDS WITH GUSTS TO 40 MPH...A LIMITED MARINE CLOUD DECK
AND ABOVE NORMAL AFTERNOON TEMPS.

LONG TERM...GFS AND EC AGREE THAT THE RATHER LARGE COOL UPPER LOW
JUST WEST OF WASHINGTON STATE WILL START TO MOVE EASTWARD LATER
WEDNESDAY AND BY LATE THURSDAY WILL BE OVER NRN IDAHO. AT THAT
POINT MDLS INDICATE THAT IT WILL STOP AGAIN AND THEN SIT AND SPIN
THROUGH AT LEAST SATURDAY. THE EFFECT OF ALL OF THIS WILL BE
PRETTY MINIMAL DOWN HERE AS THERE WILL BE LONG WAVE TROFING OVER
THE AREA THROUGH THE PERIOD THE ONLY CHANGE IS THAT THE WESTERLY
FLOW ALOFT TURNS MORE NWERLY. HGTS ARE FAIRLY HIGH. HIGH ENOUGH TO
SQUISH THE MARINE LAYER OUT OF MOST OF THE VLY AREAS. MAX TEMPS
WILL RISE AS THE MARINE LAYER IS SQUASHED AND BY LATE WEEK ALL BUT
THE IMMEDIATE COAST WILL HAVE ABOVE NORMAL MAX TEMPS.

&&

.AVIATION...16/1800Z.
LOW CONFIDENCE IN THE 18Z TAFS. FOR THE NEXT 24 HOURS...A SURGE OF
LOW LEVEL NORTHERLY FLOW WILL RESTRICT THE LOW CLOUD COVERAGE TO THE
COAST AND VALLEYS OF LOS ANGELES COUNTY AND PERHAPS PORTIONS OF
VENTURA COUNTY AS WELL. THE NORTH FLOW WILL CAUSE GUSTY WINDS IN
PORTIONS OF SANTA BARBARA COUNTY AND THIS MIGHT CAUSE LOW LEVEL WIND
SHEAR AT KSBA. THERE WILL BE STRONG GUSTY WINDS AT THE DESERT TAFS
EACH AFTERNOON FOR THE NEXT FEW DAYS. THE CENTRAL COAST MAY OR MAY
NOT HAVE LOW CLOUDS AGAIN TONIGHT...DECIDED TO PUT BROKEN SKIES IN
AT KSMX WITH LESS CLOUDINESS AT KSBP BUT IT IS A DIFFICULT CALL.

KLAX...VFR CONDITIONS WILL LAST THROUGH THE EVENING BEFORE AN EDDY
SPINS UP THE MARINE LAYER TO AROUND 2000 FEET LATE TONIGHT INTO
MONDAY MORNING WITH RESULTANT MVFR CONDITIONS. THE TIMING AND HEIGHT
OF THE CEILING ARE MAIN POINTS OF DOUBT.

KBUR...VFR CONDITIONS WILL LAST THROUGH MIDNIGHT BEFORE AN EDDY
SPINS UP THE MARINE LAYER TO AROUND 2000 FEET LATE TONIGHT INTO
MONDAY MORNING WITH RESULTANT IFR CONDITIONS. THE TIMING AND HEIGHT
OF THE CEILING ARE MAIN POINTS OF DOUBT.

&&

MARINE...16/1800Z.
A SURGE OF NORTH WINDS WILL MARCH DOWN THROUGH THE COASTAL WATERS
AND INITIATE GALE FORCE WINDS EITHER LATE THIS AFTERNOON OR EARLY
THIS EVENING. THE STRONG WINDS WILL ALSO PROMPT SMALL CRAFT
ADVISORIES FOR SOME OF THE INNER WATER ZONES THIS AFTERNOON AND ALL
OF THE INNER WATER ZONES BY MONDAY AFTERNOON. STRONG GUSTY WINDS
WILL REMAIN IN THE FORECAST ALL THE WAY THROUGH THURSDAY.

&&

.FIRE WEATHER...

A BROAD UPPER LEVEL TROUGH WILL PREVAIL ACROSS CALIFORNIA
DURING THE NEXT FEW DAYS. THIS WILL BRING INCREASING NORTHWEST FLOW
ACROSS THE SANTA BARBARA COUNTY MOUNTAINS AND SOUTH COAST...AS WELL
AS THE INTERSTATE 5 CORRIDOR AND ANTELOPE VALLEY. WINDS WILL LIKELY
BE STRONGEST MONDAY AFTERNOON THROUGH TUESDAY NIGHT...WHEN GUSTS
WILL RANGE BETWEEN 35 AND 45 MPH AT TIMES. ISOLATED GUSTS TO 50 MPH
WILL BE POSSIBLE NEAR WHITAKER PEAK. MEANWHILE...MINIMUM HUMIDITIES
ARE EXPECTED TO FALL TO BETWEEN 10 AND 20 PERCENT IN THE MOUNTAINS
AND SINGLE DIGITS IN THE ANTELOPE VALLEY. IN ADDITION...HUMIDITIES
COULD BRIEFLY FALL TO UNDER 20 PERCENT DURING THE LATE AFTERNOON AND
EARLY EVENING HOURS ACROSS PORTIONS OF THE SANTA BARBARA SOUTH COAST
AND ADJACENT FOOTHILLS DUE TO THE GUSTY SUNDOWNER WINDS. HUMIDITY
RECOVERIES WILL BE POOR DURING THE OVERNIGHT HOURS ACROSS THE
MOUNTAINS AND ANTELOPE VALLEY. THE COMBINATION OF GUSTY WINDS AND
LOW HUMIDITIES WILL BRING ELEVATED FIRE DANGER TO THE
MOUNTAINS...ANTELOPE VALLEY...AND SANTA BARBARA SOUTH COAST FOR THE
NEXT FEW DAYS...WITH BRIEF PERIODS OF CRITICAL FIRE WEATHER
CONDITIONS EACH AFTERNOON AND EVENING. RED FLAG WARNINGS HAVE NOT
BEEN ISSUED AT THIS TIME SINCE CRITICAL FIRE WEATHER CONDITIONS ARE
NOT EXPECTED TO HAVE SUFFICIENT DURATION.
