SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
330 AM PST TUE FEB 1 2011

.SYNOPSIS...

HIGH PRESSURE BUILDING INTO THE GREAT BASIN TODAY WILL BRING STRONG
AND DAMAGING OFFSHORE WINDS TO THE AREA THROUGH THURSDAY.
TEMPERATURES WILL REMAIN NEAR SEASONAL NORMALS. BY THE END OF THE
WEEK...WINDS WILL DIMINISH AND TEMPERATURES WILL GRADUALLY WARM .

&&

.SHORT TERM (TODAY-THU)...
WEAK ONSHORE FLOW WITH A GOOD ONSHORE TREND TO THE NORTH HAS
RESULTED IN A SMALL MARINE LAYER WHICH COVERS PORTIONS OF THE L.A.
COAST...THE SANTA MONICA RANGE...AND THE SAN FERNANDO VALLEY. THESE
CLOUDS WILL DISSIPATE QUICKLY AFTER SUNRISE. LOW CLOUDS HAVE ALSO
ADVECTED DOWN THE SALINAS RIVER VLY AND INTO THE PASO ROBLES AREA. A
WEAK ONSHORE PUSH ACROSS THE CENTRAL COAST HAS ALSO BROUGHT SOME LOW
CLOUDS TO THAT AREA AS WELL. A SUNDOWNER CONTINUES TO BRING ADVISORY
LEVEL WIND GUSTS TO THE PASSES AND CANYONS OF THE SANTA YNEZ RANGE
AS WELL AS THE AREAS BELOW THEM ACROSS THE SBA SOUTH COAST. HGTS AND
THICKNESS UP A LITTLE TODAY WILL BUMP TEMPS UP A DEGREE OR TWO.

BIG NEWS IS THE WIND EVENT THAT STARTS TONIGHT. HIGH PRESSURE BUILDS
INTO NEVADA. UPPER FLOW SHIFTS TO THE NE...INCLUDING THE RIGHT FRONT
EXIT REGION OF A 100 KT JET. COLD AIR STARTS AROUND MIDNIGHT AND BY
WEDNESDAY AFTERNOON THERE IS A 6 DM DECREASE IN THICKNESS. ALL OF
WHICH ADDS UP TO A BIG WIND EVENT. WINDS WILL HIT WARNING LEVELS
BETWEEN 10 PM AND MIDNIGHT IN THE LA/VTA/SANTA MONICA MTNS AS WELL
AS THE SANTA CLARITA VLY...THE WESTERN FOOTHILLS OF THE SAN FERNANDO
VLY...AND THE EASTERN PORTIONS OF VENTURA VLYS. THE MTNS WILL SEE
GUSTS OF 65 TO 70 MPH WHILE THE VLYS WILL SEE GUSTS 60 TO 65 MPH.
WIND ADVISORIES FOR GUSTS FROM 45 TO 50 MPH ARE ALSO OUT FOR THE
L.A. COAST...THE VTA COAST AND CATALINA ISLAND. THE USUALLY WIND
SHELTERED AVALON HARBOR WILL SEE 45 MPH GUSTS AND VERY ROUGH SEAS
PEOPLE WITH CONCERNS ABOUT THE HARBOR SHOULD SEE THE MARINE WEATHER
STATEMENT LAXMWSLOX FOR MORE DETAILS ABOUT THE POTENTIALLY DANGEROUS
EFFECTS OF STRONG WINDS AND LARGE WIND WAVES. THE COLD AIR ADVECTION
ENDS MID AFTERNOON WEDNESDAY AND THIS COMBINED WITH THE TYPICAL
DIURNAL PATTERN WILL ALLOW FOR A DECREASE IN THE WINDS. IT WILL
STILL BE BREEZY HOWEVER AND AREAS WHERE THERE ARE WARNINGS MAY WELL
NEED ADVISORIES. THE ONE EXCEPTION IS THE LA MTNS SPECIFICALLY THE
SAN GABRIEL RANGE WHERE THE NAM CONTINUES TO FORECAST WARNING LEVEL
WINDS THROUGH THU MORNING AND THE WIND WARNING EXTENDS THERE THROUGH
THU MORNING. THERE WILL BE ANOTHER DIURNAL BUMP UP THU MORNING AND
ANOTHER ROUND OF WIND ADVISORIES MAY BE NEEDED. SINCE THERE WILL BE
NO COLD AIR ADVECTION DURING THIS PERIOD WARNING LEVEL WINDS ARE NOT
EXPECTED.

WITH THICKNESS PLUMMETING TO 544 DM WEDNESDAY MAX TEMPS WILL COOL
INTO THE LOWER TO MID 60S DESPITE THE ADIABATIC DOWNSLOPE WARMING.
MIN TEMPS THURSDAY MORNING WILL BE VERY TRICKY WITH FAIRLY WARM
READINGS IN THE WINDY AREAS AND MUCH COLDER TEMPS IN THE WIND
SHELTERED AREAS. THURSDAY WILL BE A LITTLE WARMER AS HGTS RECOVER
AND OFFSHORE FLOW CONTINUES.

.LONG TERM (FRI-MON)...
GFS AND EC AGREE THAT A PLEASANT BUT DULL WEATHER PATTERN IS ON TAP
FOR THE EXTENDED PERIOD WITH A LARGE ELONGATED RIDGE HUGGING THE
WEST COAST AND WEAK OFFSHORE FLOW AT THE SURFACE. LOOK FOR DRY
CONDITIONS WITH MOSTLY CLEAR SKIES AND MAX TEMPS 5 TO 8 DEGREES
ABOVE NORMAL.
