SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION...UPDATE
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
530 PM PDT THU OCT 22 2015

...UPDATED AVIATION DISCUSSION...

.SYNOPSIS...

COOLER CONDITIONS WITH AREAS OF NIGHT THROUGH MORNING LOW CLOUDS AND
FOG ARE EXPECTED THROUGH TOMORROW AS ONSHORE FLOW RETURNS...BUT
TEMPERATURES WILL REMAIN SLIGHTLY ABOVE NORMAL WITH HIGH PRESSURE
MOVING IN ALOFT. WELL ABOVE NORMAL TEMPERATURES ARE EXPECTED OVER
THE WEEKEND AS ONSHORE FLOW WEAKENS. A FRONTAL SYSTEM MAY BRING
COOLER WEATHER AND A CHANCE OF RAIN BY THE MIDDLE OF NEXT WEEK.

&&

.SHORT TERM (TODAY-SUN)...VERY WEAK TROF SHOWN ON WATER VAPOR
IMAGERY MOVING THROUGH CENTRAL CALIFORNIA THIS AFTERNOON. LOW CLOUDS
HAVE BEEN INCREASING IN COVERAGE OVER THE COASTAL WATERS THIS
MORNING AND WE WILL LIKELY SEE GREATER COVERAGE OVER LAND THIS
EVENING AND OVERNIGHT WITH A 3 MB ONSHORE TREND. HOWEVER, THERE WILL
BE A FAIRLY RAPID SHIFT TO WEAK OFFSHORE FLOW BY FRIDAY MORNING AS
PRESSURES RISE BEHIND THE TROF, MAKING THE SKY FORECAST TRICKIER
THAN USUAL. IN ANY CASE WE SHOULD SEE FAIRLY EARLY CLEARING FRIDAY
WITH HIGHS UP A FEW DEGREES FROM TODAY. A LITTLE BIT OF UPPER
SUPPORT FOR SOME GUSTY NORTHEAST WINDS IN THE LA/VENTURA VALLEYS AND
MTNS BUT BELOW ADVISORY LEVELS.

A BIGGER JUMP IN TEMPS EXPECTED SATURDAY WITH ADDITIONAL OFFSHORE
FLOW AND A WARMER AIR MASS OVERALL. ON AVERAGE MOST AREAS WILL SEE
ABOUT 8 DEGREES OF WARMING SATURDAY, PUSHING HIGHS CLOSE TO 90 FOR
INLAND COASTL LOCATIONS AND LOW 90S FOR THE VALLEYS. VIRTUALLY NO
SUPPORT FOR ANY WIDESPREAD SANTA ANA WINDS BUT THERE WILL BE SOME
LIGHT NORTHEAST WINDS DURING THE MORNING AND EARLY AFTERNOON HOURS.

GRADIENTS RELAX A BIT SUNDAY AS A TROF MOVES INTO NRN CALIFORNIA BUT
AIR MASS STARTS OUT A BIT WARMER SO INLAND AREAS LIKELY TO WARM UP A
DEGREE OR TWO WHILE COASTAL AREAS COOL SLIGHTLY.

.LONG TERM (MON-THU)...MONDAY WE'LL SEE VERY BRIEF RIDGING ALOFT
BEHIND THE SUNDAY TROF BUT AIR MASS ACTUALLY COOLS SLIGHTLY AS
ONSHORE FLOW INCREASES SO WE SHOULD SEE A 3-6 DEGREE COOLING TREND
ON AVERAGE, ESPECIALLY LA/VENTURA COUNTIES. MINIMAL CHANGES TUESDAY.
WED AND THU MODELS HAVE BEEN STRUGGLING WITH A DEVELOPING SPLIT FLOW
PATTERN AND WHERE AND HOW STRONG THE LOW IN THE SOUTHERN BRANCH OF
THE SPLIT WILL BE. THE GFS/EC ENSEMBLES STILL SHOW CONSIDERABLE
VARIABILITY, THOUGH BOTH OPERATIONAL SOLUTIONS ARE FAIRLY SIMILAR
AND INDICATE A VERY GOOD CHANCE OF RAIN ACROSS THE ENTIRE AREA
DURING THAT TIME, WITH THE BEST CHANCES WED NIGHT. WHILE PREVIOUS
SOLUTIONS HAVE VARIED FROM DRY TO QUITE WET, TODAY'S SOLUTIONS SEEM
TO FIND SOME GOOD MIDDLE GROUND AND FEEL MORE CONFIDENT WITH RAIN
CHANCES. SO TODAY'S FORECAST HAS HIGHER POPS FOR WED/THU WITH MUCH
COOLER TEMPS. STILL, GIVEN THE SPLIT FLOW PATTERN EXPECT CONTINUED
MODEL VARIANCES, ESPECIALLY WITH TIMING. ALL MODELS DEVELOP STRONG
RIDGING LATE NEXT WEEK THROUGH NEXT WEEKEND FOR A RAPID WARMUP AND
POSSIBLY EVEN SOME OFFSHORE WINDS.
