SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
945 PM PST WED JAN 22 2014

UPDATED AVIATION SECTION

.SYNOPSIS...

AN UPPER-LEVEL LOW PRESSURE SYSTEM WILL NUDGE IN FROM THE EAST TO
COOL TEMPERATURES FOR THURSDAY...THEN HIGH PRESSURE SHOULD
REESTABLISH ON FRIDAY TO WARM THE AIR MASS AND CREATE OFFSHORE
FLOW. THE ONSHORE FLOW WILL BRING A MINOR COOL DOWN ON SUNDAY TO
THE COASTAL AREAS. A PACIFIC HIGH PRESSURE SYSTEM WILL MOVE OVER
ON THE REGION NEXT WEEK FOR LESS CLOUDS AND A WARMING TREND.

&&

.UPDATE...

ONSHORE FLOW CONTINUES TO DEVELOP AHEAD OF A WEAK TROUGH OF LOW
PRESSURE DROPS INTO NORTHERN CALIFORNIA. A SHALLOW MARINE LAYER
IN PLACE OVER LOS ANGELES COUNTY THIS EVENING HAS BROUGHT DENSE
FOG TO THE AREA. EARLIER...KLAX...KLGB...KTOA...AND KSMO ALL
REPORTED 1/4 MILE OR LESS IN DENSE FOG. HOWEVER...THE THREAT OF
DENSE FOG HAS SHIFTED TO INTERIOR PORTION OF THE LOS ANGELES
COUNTY COAST AS THE MARINE LAYER DEEPENS SLIGHTLY. A DENSE FOG
ADVISORY IS IN EFFECT FOR THE LOS ANGELES COUNTY COAST THROUGH 3
AM PST AND THIS ADVISORY MAY NEED TO EXPANDED FOR THE SAN GABRIEL
VALLEY AND/OR VENTURA COUNTY COAST.

THE MARINE LAYER DEPTH SHOULD CONTINUE TO DEEPEN TONIGHT AS THE
EDDY CIRCULATION GENERATES. THE MARINE LAYER STRATUS WILL CONTINUE
TO EXPAND NORTH INTO VENTURA AND THE SOUTH COAST OF SANTA BARBARA
COUNTY THROUGH THURSDAY MORNING. WITH THE ONSHORE FLOW
ESTABLISHING AND THE STRATUS CLOUDS...TEMPERATURES HAVE BEEN
COOLED THROUGH THE MARINE LAYER DEPTH FOR THURSDAY. ALSO WITH
STRATUS ALREADY ENTRENCHED ALONG THE BEACHES...MINIMUM
TEMPERATURES WERE RAISED SLIGHTLY FOR TONIGHT.

&&

.PREV DISCUSSION...

SHORT TERM...GRADIENTS THEN QUICKLY TURN OFFSHORE AS A WEATHER
SYSTEM DROPS THROUGH THE GREAT BASIN WITH SOME ENERGY MOVING BACK
WEST ACROSS NRN CALIFORNIA AND THE REST CONTINUING TO MOVE SOUTH
AND EAST THROUGH NEVADA AND UTAH. SORT OF AN UNUSUAL UPPER LEVEL
PATTERN AND THE RESULT IS A NON-TRADITIONAL OFFSHORE WIND EVENT
THAT SHOULD FOR THE MOST PART BE FAIRLY LOW GRADE IN INTENSITY.
MAYBE LOW END WIND ADVISORIES AT MOST. DAYTIME HIGHS ACROSS THE
LOWER ELEVATIONS WILL GET A SIZABLE BOOST FROM THE ADIABATIC
WARMING CAUSED BY DOWNSLOPE WINDS, BUT NOT QUITE AS WARM AS WHAT
WE SAW RECENTLY AS THE AIR MASS IS A BIT COOLER OVERALL. BY SAT
VALLEYS AND SOME INTERIOR COASTAL AREAS SHOULD BE CLOSE 80, BUT
MOST AREAS IN THE 70S.

LONG TERM (SUN-WED)...SUNDAY WE'LL SEE A BRIEF RETURN TO ONSHORE
FLOW WHICH WILL BRING SOME COOLING TO COASTAL AREAS, BUT UPPER
RIDGING ALOFT WILL MAINTAIN A WARMING TREND FOR INTERIOR AREAS. THEN
WEAK TO MODERATE OFFSHORE FLOW RETURNS EARLY NEXT WEEK ALONG WITH A
SIGNIFICANTLY WARMER AIR MASS WITH THICKNESSES APPROACHING 570
TUE/WED. IF THIS SOLUTION HOLDS WE COULD BE LOOKING AT WIDESPREAD
HIGHS IN THE 80S NEXT WEEK AND POSSIBLY SOME 90S.

.AVIATION...22/2338Z.
EXPECT STRATUS ACROSS COASTAL SECTIONS OF L.A. COUNTY AND S VTU
COUNTY TO SPREAD INTO THE S COAST OF SBA COUNTY OVERNIGHT. COASTAL
SECTIONS N OF PT CONCEPTION ARE EXPECTED TO REMAIN CLEAR. CONDS WILL
BE MOSTLY LIFR TO IFR...BUT MAY IMPROVE TO MVFR LATE. EXPECT IFR
CONDS TO PUSH INTO THE VALLEYS OF L.A. COUNTY LATE TONIGHT. SKIES
SHOULD CLEAR IN MOST AREAS BY LATE MORNING...BUT COULD LINGER RIGHT
NEAR THE COAST. EXPECT STRATUS TO PUSH INTO ALL COASTAL AREAS FAIRLY
EARLY THU EVENING.

KLAX...LOW TO MODERATE CONFIDENCE IN TAF. THERE IS A 30 PERCENT
CHANCE THAT CONDS WILL REMAIN IFR THROUGH 13Z OR 14Z. THERE IS A
20 PERCENT CHANCE CIGS WILL NOT SCATTER OUT AT ALL THU AFTERNOON.

KBUR...MODERATE CONFIDENCE IN TAF.  THERE IS A 20 TO 30 PERCENT
CHANCE THAT CIGS WILL ARRIVE AS EARLY AS 08Z. THERE IS A 10 TO 20
PERCENT CHANCE THAT CONDS WILL REMAIN VFR OVERNIGHT.

&&

.MARINE...23/0409Z.

A STRONG STORM SYSTEM OVER THE CENTRAL PACIFIC DURING THE
PAST COUPLE OF DAYS HAS GENERATED A LARGE LONG PERIOD WESTERLY SWELL
THAT WILL BUILD ACROSS THE COASTAL WATERS OF SOUTHWEST CALIFORNIA ON
THURSDAY NIGHT. THIS WILL BE THE THIRD MAJOR SWELL EVENT OF THE WEEK
AND IS EXPECTED TO PRODUCE THE HIGHEST SURF OF THE THREE EVENTS.
SURF IS EXPECTED TO PEAK ON FRIDAY...HOWEVER HIGH SURF CONDITIONS
WILL LIKELY LINGER INTO SATURDAY NIGHT. MARINE MODEL GUIDANCE
SHOWING FAVORABLE 270-280 DEGREE DIRECTION OF THIS LARGE SWELL
RELATIVE TO THE SOUTHERN CALIFORNIA COASTLINE...WITH VERY LONG
PERIODS OF 20 SECONDS OR GREATER AT THE INITIAL PORTION OF THIS
EVENT. AS A RESULT...WIDESPREAD HIGH SURF CONDITIONS ARE EXPECTED
ACROSS WEST FACING BEACHES. ACROSS THE CENTRAL COAST...BREAKERS OF
10 TO 15 FEET WILL BE COMMON WITH MAX SETS UP TO 19 FEET POSSIBLE.
FOR WEST FACING BEACHES OF LOS ANGELES AND VENTURA
COUNTIES...BREAKERS OF 7 TO 10 FEET ARE EXPECTED WITH MAX SETS UP TO
12 FEET POSSIBLE. THE VERY LONG WAVE PERIOD WILL ALSO ALLOW FOR MORE
WAVE ENERGY TO REFRACT AND IMPACT PORTIONS OF THE SANTA BARBARA
SOUTH COAST...WHERE LOCAL BREAKERS UP TO 8 FEET WILL BE POSSIBLE.
MAJOR IMPACTS OF THIS HIGH SURF EVENT INCLUDE STRONG RIP
CURRENT...SNEAKER WAVES...AND POSSIBLE MINOR BEACH EROSION.

&&

.FIRE WEATHER...22/2320Z.

ELEVATED FIRE WEATHER CONCERNS CAN BE EXPECTED TONIGHT THROUGH
THURSDAY OVER PORTIONS OF THE VENTURA AND LOS ANGELES COUNTY
MOUNTAINS...THE SANTA CLARITA VALLEY AND THE VENTURA COUNTY VALLEYS
DUE TO LOCAL GUSTY NORTHEAST WINDS AND LOW HUMIDITIES. THERE SHOULD
BE POOR HUMIDITY  RECOVERIES OVER INTERIOR AREAS AGAIN TONIGHT...
OTHERWISE GOOD RECOVERIES ARE EXPECTED.

AN INCREASE IN OFFSHORE FLOW CAN BE EXPECTED THURSDAY NIGHT...WITH
GUSTY EAST TO NORTHEAST WINDS OVER PORTIONS OF VENTURA AND LOS
ANGELES COUNTIES BY LATER THURSDAY NIGHT AND CONTINUING FRIDAY.
GUSTY SOUTHEAST WINDS WILL ALSO AFFECT MUCH OF SANTA BARBARA AND SAN
LUIS OBISPO COUNTIES. HUMIDITIES ARE FORECAST TO FALL BELOW 20
PERCENT ACROSS MUCH OF VENTURA AND LOS ANGELES COUNTIES AS WELL AS
THE SANTA BARBARA COUNTY MOUNTAINS LATER THURSDAY NIGHT OR EARLY
FRIDAY...WITH THE POSSIBILITY OF SEVERAL HOURS OF CRITICAL FIRE
WEATHER CONDITIONS OVER THESE AREAS MAINLY ON FRIDAY INTO FRIDAY
EVENING. GUSTY SOUTHEAST WINDS AND LOWERING HUMIDITY WILL ALSO BRING
ELEVATED FIRE WEATHER CONCERNS FOR MUCH OF THE REST OF SAN LUIS
OBISPO AND SANTA BARBARA COUNTIES ON FRIDAY.

ABOVE NORMAL TEMPERATURES AND LOW HUMIDITIES ARE EXPECTED OVER THE
WEEKEND AS WEAKER OFFSHORE FLOW PREVAILS. UPPER LEVEL HIGH PRESSURE
IS EXPECTED TO BUILD ALONG THE AND OFF WEST COAST TUESDAY AND
WEDNESDAY WITH THE POTENTIAL FOR MUCH ABOVE NORMAL TEMPERATURES...
GUSTY OFFSHORE WINDS AND CONTINUED LOW HUMIDITIES OVER THE FIRE
WEATHER DISTRICT.
