SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
215 PM PDT THU OCT 15 2009

.SYNOPSIS...
A WARMING TREND BRINGING DRIER CONDITIONS WILL START THIS AFTERNOON
AND LAST INTO SATURDAY. A WEAK OFFSHORE EVENT WILL SET UP LATE
TONIGHT BRINGING LIGHT NORTHEAST BREEZES AND WILL LAST INTO FRIDAY
MORNING. COOLER WEATHER WITH A RETURN OF THE MARINE LAYER WILL START
SUNDAY AND LAST INTO EARLY NEXT WEEK.

&&

.SHORT TERM (TODAY-SUNDAY)...
GRADIENTS TRENDING A HEALTHY -5MB OFFSHORE THIS AFTERNOON...WHICH
ONLY ENHANCES THE EFFECTS OF THE 590DM RIDGE NUDGING IN FROM THE
SOUTHWEST. TO LITTLE SURPRISE TEMPS UP QUITE A BIT...ABOUT 5-15
DEGREES ON AVERAGE WITH SOME +20 TRENDS IN THE INTERIOR VALLEYS AND
MTNS. WINDS MAY BE THE CONCERN TONIGHT INTO FRIDAY...AS MODERATE
SURFACE HIGH PRESSURE OVER OREGON BUILDS INTO IDAHO...RESULTING IN
CONTINUED OFFSHORE TRENDS. INITIALLY...THIS WILL ALLOW FOR GUSTY
NORTHERLY FLOW TO FORM OVER THE CENTRAL COAST...WHICH SHOULD PRIME
SRN SBA COUNTY FOR A MODERATE SUNDOWNER TONIGHT. SBA-SMX GRADS LOOK
TO PEAK AT -4MB...BUT WITH THE PRESENCE OF A DECENTLY STRONG LOW
LEVEL INVERSION...THE WINDS MAY STRUGGLE TO REACH THE COAST. WITH
THAT IN MIND...PLAYING IT SAFE AND WENT AHEAD AND ISSUED A WIND
ADVISORY FOR SRN SBA CO...HIGHLIGHTING THE SANTA YNEZ RANGE AND
DOWNSTREAM FOOTHILLS. AS THE HIGH SHIFTS TO THE EAST...THE FLOW WILL
FOLLOW SUIT AND SHIFT TO THE NORTHEAST OVERNIGHT TONIGHT. THIS WILL
CONTINUE THE THREAT FOR SRN SBA COUNTY...BUT SHIFT THE AREA OF
CONCERN TO MONTECITO. THIS WILL ALSO PUSH DECENT WINDS DOWN THROUGH
THE I-5 CORRIDOR TONIGHT AS LAX-BFL STRENGTHEN TO -6MB. ISOLATED
ADVISORY GUSTS ARE LIKELY...BUT DID NOT ISSUE ONE FOR NOW. BY LATER
FRI...FLOW WILL BE NORTHEAST...AND MAKE FOR SOME BREEZY CONDITIONS
IN THE VALLEYS. THE COASTS OF LA/VTU CO COULD SEE SOME LOCALLY
BREEZY WINDS...BUT WITH THE OVERALL WEAKNESS OF THE GRADIENT AND
SUPPORTING FLOW ALOFT...THE INVERSION MAY KEEP WINDS AT BAY.

THIS WIND WILL HAVE A BIG EFFECT ON THE STRATUS...WHICH HAS SCOURED
OUT OVER THE COASTAL AREAS...BUT STILL LOOMS OFF THE COAST. IF THE
INVERSION PROVES STRONG ENOUGH TO KEEP THE WINDS CONFINED TO THE
VALLEYS AND MOUNTAINS...THEN THE COASTAL AREAS SHOULD SEE SOME MORE
CLOUDS AND COOLER THAN ADVERTISED TEMPS. OTHERWISE...ANOTHER 10
DEGREE WARMUP LOOKS NEARLY CERTAIN FOR TOMORROW...WITH MOST VALLEY
AREAS FIRMLY INTO THE 90S. THE NORTHEAST WIND COULD EVEN AFFECT THE
CENTRAL COAST AS 30 KT WINDS AT 1000 FT TRY TO MIX DOWN. THIS SHOULD
CREATE A ROASTY DAY FOR SLO AND NRN SBA CO...WITH 80S AND 90S FIRMLY
SET.

SATURDAY LOOKS VERY SIMILAR TO FRI...EXCEPT FOR MUCH WEAKER
NORTHEAST FLOW...AND SLIGHTLY COOLER COASTS AND WARMER INTERIORS.
VALLEYS SHOULD LARGELY BE UNCHANGED. SUNDAY STILL LOOKS COOLER...AS
GRADS QUICKLY TURN ONSHORE AND HEIGHTS LOWER. A SMALL 545DM LOW
SHOULD PUSH INTO OREGON BY SUN NIGHT...WITH A WEAK TROUGH JUST
DOWNSTREAM PUSHING DOWN THE CA COAST ON SUN. ALL THIS ADDS UP TO A
HEALTHY 10 DEGREE OR SO COOLING TREND ON SUN...AND A LIKELY RETURN
OF THE MARINE LAYER IF DID END UP SCOURING OUT ON FRI AND SAT. TEMPS
SHOULD BE RIGHT ABOUT NORMAL...EXCEPT FOR SOME EXTRA COOLING OVER
SLO COUNTY. NORTHERLY FLOW WILL BE ON THE RISE AS WELL WITH
THIS...ESPECIALLY ALONG THE CENTRAL COAST.

.LONG TERM (MONDAY-THURSDAY)...
AS THE AFOREMENTIONED SYSTEM WORKS THROUGH THE WEST COAST...MODELS
CONTINUE TO SHOW A DRY FRONT PUSHING DOWN THE CA COAST ON MON.
ALTHOUGH THIS MAY PRODUCE A FEW CLOUDS NORTH OF SBA...IT WILL MOSTLY
BE A WIND MAKER. COULD SEE SOME NEAR ADVISORY NORTHERLY WINDS OVER
SLO AND SBA COUNTIES ON MON...AS WELL AS THE LA MTNS MON NIGHT INTO
TUE. THE AIRMASS COOLS AS WELL...AND MON SHOULD BE THE COLDEST OF
THE FORECAST PERIOD WITH BELOW NORMAL TEMPS AND A FAIRLY DEEP MARINE
LAYER.

THIS SYSTEM LOOKS COLD ENOUGH TO PRODUCE DECENT HIGH PRESSURE OVER
THE GREAT BASIN BY TUE OR WED. THIS SHOULD SET UP ANOTHER ROUND OF
WEAK-MODERATE OFFSHORE FLOW...WHICH WHEN COUPLED WITH A BUILDING
RIDGE TO THE WEST...SHOULD RESULT IN ANOTHER WARMUP. FORECAST STILL
FAIRLY CONSERVATIVE WITH THE WARM UP...SINCE TIMING MAY STILL BE
UNCERTAIN...BUT ABOVE NORMAL TEMPS LOOKS GOOD BY THE MIDDLE OF NEXT
WEEK.

&&

.AVIATION...15/1955Z.
VFR CONDITIONS WILL CONTINUE IN MOST LOCATIONS OVERNIGHT AND INTO
FRIDAY. THE ONLY EXCEPTION WOULD BE IMMEDIATE COASTAL SECTIONS WHERE
THERE IS A 40 PERCENT CHANCE OF LOW CLOUDS AND DENSE FOG RETURNING
TO THE COAST LATE TONIGHT BEFORE IT CLEARS RAPIDLY FRIDAY MORNING.
DEFINITELY A LOW CONFIDENCE FORECAST FOR THE IMMEDIATE COAST.

KLAX...A LOW CONFIDENCE FORECAST. THERE IS A 40 PERCENT CHANCE OF
LOW CLOUDS AND DENSE FOG RETURNING TO THE COAST LATE TONIGHT AND
CLEARING AGAIN EARLY FRIDAY MORNING. THE CURRENT TAF DOES NOT
INCLUDE A CEILING...HOWEVER A CEILING IS DEFINITELY A POSSIBILITY.

KBUR...GOOD CONFIDENCE IN VFR CONDITIONS THROUGH FRIDAY.
