SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
130 PM PST SUN FEB 1 2009

.SHORT TERM (TODAY-WEDNESDAY)...
TEMPS DOWN ACROSS THE BOARD AS A SHALLOW MARINE LAYER HAS ASSERTED
ITSELF OVER THE AREA. SOME FOG IS STILL LINGERING ALONG THE
COAST...WHICH HAS KEPT TEMPS BELOW THE LOWER 60S AT PLACES LIKE LAX.
THE CENTRAL COAST AND INTERIOR SLO COUNTY HOWEVER HAVE BEEN
SPARED...AS NORTHEAST FLOW HAS ACTUALLY BROUGHT A DECENT DOSE OF
WARMING. SOME BREEZY NORTHEAST WINDS HAVE ALSO SURFACED OVER LA/VTU
COUNTY.

OFFSHORE GRADS WILL INCREASE OVERNIGHT AS A HEALTHY 1040MB SURFACE
HIGH STRENGTHENS OVER NRN UTAH. THIS SHOULD STRENGTHEN NORTHEAST
FLOW OVER LA/VTU CO TONIGHT INTO MON...AND WILL SOON BE ISSUING A
WIND ADVISORY FOR THE MTNS AND SANTA CLARITA VLY. WENT BACK AND
FORTH ON WHETHER TO ISSUE ONE...AS THE UPPER LEVEL SUPPORT IS RATHER
PALTRY...BUT WITH LAX-DAG PEAKING NEAR -6MB AND A 581 DM RIDGE
BUILDING IN FROM THE WEST...SOME ADVISORY LEVEL GUSTS SHOULD PUSH
THROUGH THOSE PASSES AND CANYONS...AT LEAST INTO MON AFTERNOON
BEFORE WEAKENING. THESE WINDS WILL PUSH INTO THE OTHER VLYS AS
WELL...BUT OTHER THAN A FEW ISOLATED SPOTS...SHOULD NOT BE WINDY
ENOUGH TO WARRANT INCLUSION. THIS NORTHEAST FLOW SHOULD ALSO KILL
THE MARINE LAYER...SINCE THE INVERSION IS RATHER WEAK. TEMPS WILL
RISE AS WELL ON MON...WITH HIGHS IN THE 70S TO NEAR 80 IN THE COASTS
AND VLYS EXPECTED ONCE AGAIN...FROM LA UP TO SLO COUNTY.

OFFSHORE GRADS AND THE RIDGE ALOFT WEAKEN ON TUE...BUT THE AIRMASS
REMAINS DRY AND IT WILL BE WARM ONCE AGAIN. SOME BREEZY CONDITIONS
ARE ALSO EXPECTED...BUT SHOULD STAY WELL BELOW ADVISORY.

WED WILL FINALLY START A CHANGE FROM THE DRY OFFSHORE FLOW THAT WE
WERE LOCKED IN FOR MOST OF JAN. SAT IMAGERY SHOWS A LOW SPINNING
SOUTH OF THE ALEUTIAN ISLANDS...WHICH WILL CONTINUE TO MOVE
SOUTHEASTWARD. MODELS ARE IN VERY GOOD AGREEMENT WITH THE TRACK OF
THIS SYSTEM...CUTTING IT OFF FROM THE PREVAILING JET TUE
NIGHT...THEN SPINNING IT TO JUST OFF THE CA COAST ON WED. THIS WILL
BRING INCREASED CLOUDS AND COOLER TEMPS EVERYWHERE ON WED...AS WELL
AS SOME BREEZY SOUTHERLY FLOW TO SLO AND NRN SBA COUNTIES. ...BU THE
STORY DOES NOT END THERE...

.LONG TERM (THURSDAY-SUNDAY)...
THE AFOREMENTIONED SYSTEM WILL PUSH ASHORE WED NIGHT AND THU. THIS
WILL BRING CLOUDY SKIES...MUCH COOLER TEMPS...AND A GOOD SHOT OF
RAIN TO THE REGION. THE RAIN SHOULD START ALONG THE CENTRAL COAST
EARLY ON THU...THEN PUSH DOWN THROUGH LA COUNTY BY THU EVENING.
ALTHOUGH THE TIMING MAY BE MODIFIED SLIGHTLY AS WE NEAR THE
EVENT...THE MODELS AND ENSEMBLES ARE SHOWING REMARKABLE AGREEMENT
WITH THE PLACEMENT OF THIS SYSTEM...AND CONFIDENCE IS GROWING. THE
ONE DETAIL HOWEVER THAT STILL IS A BIT UNCERTAIN IS THE AMOUNT OF
RAIN. SOLUTIONS VARY AS TO HOW MUCH MOIST SOUTHERLY FLOW WILL BE
OVER THE AREA...AND HOW FAR SOUTH IT GETS. SNOW LEVELS WILL BE ABOVE
6000 FEET TO START ON THU.

ANOTHER LOW IS EXPECTED TO ROTATE AROUND THE PREVIOUS SYSTEM ONCE IT
OPENS UP THU NIGHT. THIS NEW SYSTEM LOOKS TO PUSH DOWN THE CA COAST
FRI AND FRI NIGHT...KEEPING THE END OF THE WEEK WET. THIS LOW SHOULD
THEN DIP FURTHER SOUTH...WHICH WOULD LOWER SNOW LEVELS TO BETWEEN
4500 AND 5500 FEET ON FRI AND SAT. THIS TRACK WOULD ALSO BRING A
THREAT OF THUNDERSTORMS...BUT HOLDING OFF ADDING TO FORECAST FOR
NOW...AND WILL WAIT TILL WE GET A LITTLE CLOSER TO THE EVENT BEFORE
THROWING INTO THE MIX. AS FAR AS AMOUNTS GO...THERE IS STILL
SOME UNCERTAINTY WITH THE SOUTHERLY FLOW AND EXACT TRACK OF THE
SYSTEMS IN QUESTION...BUT SOMEWHERE BETWEEN 1.00-2.50 INCHES TOTAL
RAINFALL FOR THE TWO SYSTEMS SEEMS LIKE A GOOD STARTING POINT.

THE LAST SYSTEM SHOULD GIVE WAY TO DRYING AND WARMING NORTHERLY FLOW
BY THE BEGINNING OF NEXT WEEK.

.AVIATION...01/1730Z.

STRATUS/FOG BURNED OFF THE COAST AT THIS TIME...WITH ONLY SOME
MVFR VSBY RESTRICTIONS AT COASTAL TAF SITES. EXPECT THESE MVFR
VSBYS TO DISSIPATE BY 20Z. WITH EXPECTED OFFSHORE FLOW TONIGHT...
DO NOT ANTICIPATE MARINE LAYER TO RETURN TO ANY COASTAL SITES.
HOWEVER...SOME MVFR VSBYS ARE EXPECTED AT KPRB LATE TONIGHT AS
NORTHEASTERLY FLOW BRINGS IN SOME MOISTURE FROM THE SAN JOAQUIN
VALLEY. NO SIGNIFICANT WIND ISSUES ARE EXPECTED...ALTHOUGH SOME
WIND SHEAR AND TURBULENCE IS POSSIBLE LATE TONIGHT AT KBUR AND
KVNY.

KLAX...HIGH CONFIDENCE IN 18Z TAF. MVFR VSBYS SHOULD DISSIPATE
BY 20Z...WITH VFR CONDS EXPECTED FOR THE REST OF THE TAF PERIOD.
SOME LIGHT EASTERLY WINDS MAY SURFACE TOWARDS MONDAY MORNING...
BUT SHOULD REMAIN AT 4-6 KNOTS.

KBUR...HIGH CONFIDENCE IN 18Z TAF. THERE IS A CHANCE THAT SOME
LLWS AND TURBULENCE COULD AFFECT THE AIRFIELD AFTER 12Z.
