High Wind in California, June 4, 2008

SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
830 PM PDT TUE JUN 3 2008

.UPDATE...AN UPDATE IS NOT ANTICIPATED THIS EVENING. STRONG
DESCENDING AIR WITHIN THE NORTHWEST FLOW WILL PERSIST OVERNIGHT AND
GALES WILL PREVAIL NEAR SHORE WITH GUSTS AROUND 50 MPH THROUGH
CANYONS ON THE SB SOUTH COAST AND IN THE VTU AND LA COUNTY MOUNTAINS
TONIGHT.

&&

.SHORT TERM (TODAY-FRIDAY)...
TEMPS UP FOR THE MOST PART...SAVE FOR THE LOWER PARTS OF LA COUNTY
THAT SAW MORE STRATUS THAN YESTERDAY. POOR STRATUS COVERAGE TO THE
NORTH REALLY HELPED TEMPS WARM UP OVER SLO AND NRN SBA COUNTIES...
WHERE 3 TO 8 DEGREES OF WARMING WAS REALIZED. NORTHERLY WINDS ARE
BEGINNING TO PICK UP OVER THE REGION ONCE AGAIN AND THE WIND
ADVISORIES STILL LOOK GOOD. WILL GET PRETTY WINDY IN THE MTNS
TONIGHT...AND SHOULD SEE A FEW GUSTS WELL INTO THE 50 MPH RANGE OVER
LA CO...WITH GUSTS JUST TOUCHING 50 MPH IN SBA CO. WIND ADVISORIES
ARE IN PLAY THROUGH THU MORNING IN MOST AREAS...THOUGH EXPECTING
MOST OF THE AREA TO SEE A BREAK LATE WED MORNING AND EARLY
AFTERNOON. SINCE THIS BREAK WILL BE BRIEF...KEEPING THE ADVISORIES
IN PLAY FOR A LONGER PERIOD. THE CENTRAL COAST IS AN EXCEPTION...
WITH A LONGER BREAK EXPECTED LATE THIS EVENING THROUGH EARLY WED
AFTERNOON. WENT AHEAD AND SHORTENED THAT ADVISORY AS A RESULT...WITH
THE IDEA THAT ANOTHER ONE WILL LIKELY BE NEEDED FOR WED AFTERNOON
AND EVENING.

AN UPPER LEVEL LOW WILL BREAK OFF OF A DEEP 530 DM LOW JUST SOUTH OF
ALASKA TONIGHT...AND QUICKLY MOVE SOUTHEAST INTO NEVADA BY WED
AFTERNOON. THIS LOW WILL DO A NUMBER OF THINGS TO THE AREA TOMORROW.
FIRST...EXPECTING THE MARINE LAYER TO DEEPEN...AND STRATUS COVERAGE
TO INCREASE OVER MUCH OF THE COAST AND VALLEYS BY WED MORNING. SOME
SPOTS MAY EVEN SEE A LITTLE DRIZZLE. ON THE OTHER HAND THE INVERSION
IS NOT TERRIBLY STRONG...SO THERE IS A CHANCE THAT THE STRATUS DOES
NOT FORM WITH AS MUCH GUSTO AS ADVERTISED. LOWERED THICKS AND
INCREASED MARINE LAYER SHOULD COOL TEMPS A BIT AS WELL. SOME
MOISTURE TO THE NORTH WILL ALSO BRING A SLIGHT CHANCE OF SOME LIGHT
SHOWERS TO THE NORTH FACING SLOPES. THIS LOW WILL ALSO KEEP THE
NORTHERLY WINDS BUZZING...AS A DECENT NORTHERLY JET WILL PASS OVER
SOCAL WED NIGHT. ALTHOUGH THE COLD AIR ADVECTION IS
UNIMPRESSIVE...THE PLACEMENT OF THIS JET SHOULD ENHANCE THE HEALTHY
PRESSURE GRADIENT THAT FORMS...ESPECIALLY OVER THE HIGHER TERRAIN.
SOME NORTHERLY FLOW MAY EVEN FILTER DOWN INTO THE COASTAL AREAS BY
THU MORNING.

THINGS SHOULD RECOVER ON THU AND FRI...AS STRATUS COVERAGE WILL BE
WEAKENED DUE TO THE NORTHERLY FLOW AND THE PASSAGE OF THE
AFOREMENTIONED SYSTEM. NOT ONLY THAT...BUT ONSHORE GRADS WEAKEN AND
EVEN LOOK TO GO EVER-SO-SLIGHTLY OFFSHORE THU AND FRI MORNING. ADD
SOME NICE RIDGING THAT NUDGES IN FROM THE WEST...AND TEMPS SHOULD BE
ON THE UP AND UP TO CLOSE OUT THE WORK WEEK.

.LONG TERM (SATURDAY-TUESDAY)...
TEMPS LOOK TO TAKE ANOTHER SMALL HIT OVER THE WEEKEND...BUT SHOULD
NOT GET MUCH BELOW NORMAL. THE GFS AND ECMWF ARE IN LINE WITH A
SHORTWAVE TROUGH PASSING TO THE NORTH...WHICH WOULD COOL THE AIRMASS
A BIT AND HELP STRENGTHEN ONSHORE GRADS. IT COULD ALSO GET A LITTLE
BREEZY ALONG THE CENTRAL COAST AND IN THE MTNS AND DESERTS AS A
RESULT. THE GFS AND ECMWF ALSO AGREE IN PUSHING THIS TROUGH TO OUR
EAST BY MONDAY...THOUGH A NUMBER OF THE ENSEMBLES HINT THAT THIS
SOLUTION IS NOT SET IN STONE JUST YET. WOULD NOT BE SURPRISED IF THE
LOW LINGERS AN EXTRA DAY. EITHER WAY...LOOKS LIKE A NICE WARM UP IS
IN STORE FOR NEXT WEEK...AS A HEALTHY 590DM RIDGE CENTERED TO THE
WEST REPLACES THE TROUGH. THIS SHOULD HELP DOWNTOWN LA AND SLO TOWN
TO PUSH NEAR 80 BY MIDWEEK...AND SOME VALLEYS GETTING CLOSE TO 90.

&&

.AVIATION...4/0000.
MODERATE UPPER LEVEL NORTHWEST FLOW WILL PREVAIL OVER THE AREA WHILE
A RIDGE OF HIGH PRESSURE PERSIST UPSTREAM. THE MARINE LAYER WAS
APPROXIMATELY 1.3KFT THIS AFTERNOON...THE DEPTH WILL VARY SLIGHTLY
OVER NIGHT THEN THERE IS A CHANCE IT WILL DEEPEN TO AROUND 2.1KFT
WEDNESDAY MORNING THROUGH EARLY AFTERNOON. A MODERATE ONSHORE
PRESSURE GRADIENT WILL BECOME MODERATE NORTHERLY OVERNIGHT WHILE A
CATALINA EDDY REDEVELOPS. A WEAK TO MODERATE ONSHORE PRESSURE
GRADIENT WILL LIKELY REDEVELOP OVER THE BIGHT WEDNESDAY.

KLAX...LOW CLOUDS WILL VERY LIKELY REDEVELOP AND THERE IS A LOW
CHANCE CIGS WILL DEVELOP EARLIER TONIGHT THAN THE PREVIOUS TWO
NIGHTS. THERE IS A CHANCE CIGS WILL LINGER THROUGH EARLY AFTERNOON
AS WELL. IT IS VERY LIKELY LOW LEVEL SOUTHEAST FLOW WILL DEVELOP AND
PREVAIL 10 KT OR LESS WEDNESDAY MORNING THEN BECOME SOUTHWEST IN THE
EARLY AFTERNOON.

KBUR...LOW CLOUDS WILL VERY LIKELY DEVELOP AND THERE IS A LOW CHANCE
CIGS WILL DEVELOP EARLIER TONIGHT THEN THE PREVIOUS TWO NIGHTS.
THERE IS A CHANCE CIGS WILL LINGER THROUGH EARLY AFTERNOON AS WELL.

VIRTUALLY CERTAIN - 95-100%
VERY LIKELY       - 80-95%
LIKELY            - 60-80%
CHANCE            - 30-60%
NOT VERY LIKELY   - 20% OR LESS
