NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
845 PM PDT MON APR 11 2005

.SHORT TERM...SATELLITE IMAGERY SHOWING MOSTLY CLEAR SKIES EXCEPT
FOR A FEW HIGH CLOUDS DRIFTING ACROSS THE AREA. HAVE ADDED SOME
LOCALLY GUSTY NORTH WINDS TONIGHT AND TUESDAY MORNING ACROSS SBA
COUNTY SOUTH COAST AND MOUNTAINS...WITH CURRENT SBA-SMX GRADIENT
AT -3.2 MB. THIS WILL ONLY BE A PREVIEW OF THINGS TO COME AS NEXT
COUPLE OF NIGHTS LOOK TO BE QUITE WINDY ACROSS ZONES 39 AND 52.
LATEST ETA 12 MODEL CONTINUES TO ADVERTISE IMPRESSIVE NORTH TO
NORTHEAST PRESSURE GRADIENT BETWEEN SBA AND BAKERSFIELD (ON THE
ORDER OF -6 TO -7 MB) LATE TUESDAY NIGHT INTO WEDNESDAY MORNING...
AND AGAIN LATE WEDNESDAY NIGHT INTO THURSDAY MORNING. THIS STEEP
PRESSURE GRADIENT BEING DRIVEN BY A STRONG LOW LEVEL THERMAL
GRADIENT BETWEEN THE SOUTHERN SAN JOAQUIN VALLEY AND SBA COUNTY
COAST. WHILE THE PRESSURE GRADIENT IS RATHER IMPRESSIVE WITH THIS
EVENT...THE UPPER SUPPORT IS QUITE MINIMAL...SO DO NOT EXPECT
A REALLY HUGE EVENT. NONETHELESS...WOULD EXPECT WIND ADVISORIES
POSTED DURING THE NEXT COUPLE OF NIGHTS...AND AJUSTED ZONES
ACCORDINGLY TO REFLECT NECESSARY WIND SPEEDS. IN ADDITION TO
THE GUSTY WINDS ACROSS SBA COUNTY...WOULD EXPECT SOME GUSTY NORTHWEST
TO NORTH WINDS ACROSS THE LA/VTU MOUNTAINS...ESPECIALLY ALONG THE
INTERSTATE 5 CORRIDOR...WHERE THERE WILL LIKELY BE WIND GUSTS OVER
40 MPH TUESDAY NIGHT THROUGH THURSDAY MORNING.

WITH AN INCREASING NORTHERLY GRADIENT ON TUESDAY AND SLIGHTLY HIGHER
950 MB TEMPERATURES EXPECTED...LOOK FOR A COUPLE OF DEGREES WARMING
IN THE VALLEYS ON TUESDAY. LITTLE CHANGE IN TEMPERATURES EXPECTED
IN OTHER AREAS. IT NOW APPEARS THAT COOLING TREND FOR WEDNESDAY WILL
BE MINIMAL SINCE ETA-12 CONTINUES TO HOLD ONTO A FAIRLY GOOD NORTHERLY
FLOW PATTERN THROUGH MUCH OF THE DAY. WHILE THERE MAY BE SOME COLD
AIR ADVECTION ACROSS THE INTERIOR VALLEYS AND MOUNTAINS ON
WEDNESDAY...THE DRIER NORTHERLY FLOW PATTERN SHOULD KEEP TEMPERATURES
FAIRLY WARM ACROSS COASTAL AND COASTAL VALLEY AREAS ON WEDNESDAY.

.LONG TERM...OVERALL TROF PATTERN TO CONTINUE THROUGH THE WEEKEND, 
THOUGH ONSHORE FLOW WILL WEAKEN ENOUGH TO ALLOW TEMPS TO WARM UP A 
FEW DEGREES SAT AND SUN. THIS WILL BE BRIEF AS ANOTHER TROF DIGS 
SOUTH ALONG THE WEST COAST ON MONDAY FOR AN INCREASE IN ONSHORE 
FLOW, COOLER TEMPS, AND POSSIBLY SOME MARINE LYR CLOUDS AS WELL.

.LOX WATCHES/WARNINGS/ADVISORIES...
SMALL CRAFT ADVISORY...(LAXCWFLOX).
