SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
925 AM PST MON JAN 2 2006

.SHORT TERM (TODAY)...TODAYS THE BIG DAY AND THE STORM IS PRETTY
MUCH BEHAVING AS EXPECTED. THERE WAS A SLIGHT DELAY IN THE ONSET OF
HEAVY RAIN FOR VENTURA AND LA COUNTIES, AND RAINFALL SO FAR HASNT
BEEN QUITE AS MUCH AS WE THOUGHT AT LOWER ELEVATIONS (THOUGH STILL
IMPRESSIVE), BUT THE SOUTH FACING MOUNTAINS ARE GETTING PUMMELED
WITH HEAVY RAIN (6-8 IN. SO FAR) AND EXTREMELY GUSTY WINDS (>80 KTS
IN SOME PLACES).

THE BACK EDGE OF THE COLD FRONT IS MOVING THROUGH CENTRAL SBA COUNTY
THIS MORNING THOUGH THE TROF AXIS IS STILL OFFSHORE SO SURFACE WINDS
ARE STILL OUT OF THE SOUTH EVEN WELL OFFSHORE. THIS INITIAL BAND
WILL MOVE THROUGH VENTURA AND LA COUNTIES THIS MORNING, AFTER WHICH
TIME THE RAIN WILL BECOME MORE SCATTERED IN NATURE. WE ALSO WILL
HAVE TO KEEP A VERY CLOSE EYE ON POSSIBLE AFTERNOON CONVECTION AS
THE COLD AIR MOVES ONSHORE AND STRONG LOW LVL SHEAR DEVELOPS.

MADE SOME CHANGES TO THE ZONES THIS MORNING, MAINLY TO BEEF UP WINDS
AT LOWER ELEVATIONS TO AT LEAST ADVISORY LEVELS AND ALSO TO UPGRADE
THE COASTAL FLOOD WATCH ALONG THE CENTRAL COAST TO COASTAL FLOOD
ADVISORY AS THE TIDE PEAKS THIS MORNING.

*** LONG TERM FROM PREVIOUS DISCUSSION ***

.LONG TERM (TUE-SUN)...MEDIUM RANGE MODELS ARE IN PRETTY GOOD
AGREEMENT THOUGH THE WEEK. LOOK FOR CONDITIONS TO IMPROVE ON TUESDAY
AND LOOK EVEN BETTER WEDNESDAY THROUGH FRIDAY WITH OFFSHORE FLOW AND
MOSTLY SUNNY SKIES AND UNSEASONABLY WARM TEMPERATURES...HIGHS INTO
THE 70S WED THRU FRI AT SOME LOCATIONS. A STORM MOVES ONSHORE NORTH
OF THE REGION OVER THE WEEKEND...PRODUCING THE SLIGHTEST OF CHANCES
FOR PRECIPITATION NORTHERN MOST PORTIONS OF SLO COUNTY AND COOLER
TEMPERATURES ELSEWHERE SAT THRU SUN.

&&

.AVIATION...
THE COLD FRONT ASSOCIATED WITH THE STRONG UPPER TROUGH OFF THE COAST
WAS FINALLY BEGINNING TO ACCELERATE TO THE EAST AS THE UPPER TROUGH
WAS GETTING KICKED EAST BY UPSTREAM ACTIVITY. THE FRONT WILL
GENERATE HEAVY RAIN AND STRONG GUSTY SOUTH WINDS OUT AHEAD OF THE
FRONTAL SURFACE. THE TIMING IS BECOMING MORE CERTAIN WITH THE
HEAVIEST ACTIVITY NOW PUSHING INTO THE COASTAL SECTIONS NORTH OF
POINT CONCEPTION. THE HEAVY RAIN AND GUSTY WINDS WILL PUSH INTO
SECTIONS SOUTH OF POINT CONCEPTION DURING THE EARLY MORNING HOURS
AFTER SUNRISE. ISOLATED THUNDERSTORMS ARE ALOS A POSSIBILITY. EAST
TO SOUTHEAST WINDS MAY REACH SPEEDS OF 25 KT WITH GUSTS TO 35 KT IN
THE MOST EXPOSED LOCATIONS JUST BEFORE FRONTAL PASSAGE. ONCE THE
FRONT PASSES THROUGH THE REGION...THE WINDS WILL SHIFT TO THE WEST
TO SOUTHWEST AND DECREASE WHILE THE RAIN SUBSIDES.

&&

.MARINE...STILL ON TRACK FOR MAJOR SWELL/SURF EVENT ACROSS THE AREA
TONIGHT THROUGH TUESDAY. MODELS STILL INDICATE LONG-PERIOD WESTERLY
SWELLS BUILDING TO AROUND 20 FEET ACROSS THE OUTER WATERS...AND TO
AROUND 13 FEET ACROSS THE INNER WATERS. GIVEN THE SWELL
HEIGHTS...WILL KEEP THE HIGH SURF ADVISORIES IN EFFECT FOR COASTAL
AREAS THROUGH TUESDAY. EXPECTING BREAKERS OF 7 TO 10 FEET WITH MAX
SETS TO 12 FEET THROUGH TUESDAY. WITH MORNING HIGH TIDES TO REACH
AROUND 6.5 FEET THE NEXT COUPLE OF MORNING...COASTAL FLOODING WILL
BE A CONTINUED THREAT. SO...WILL ALSO KEEP COASTAL FLOOD WATCH IN
EFFECT THROUGH TUESDAY.

IN SHORTER TERM...SE WINDS AHEAD OF FRONT WILL PRODUCE GALE FORCE
WINDS ACROSS THE COASTAL WATERS TONIGHT/MONDAY MORNING...BEFORE
TURNING TO THE WEST MONDAY AFTERNOON. AS THE FRONT MOVES
THROUGH...THUNDERSTORMS WILL ALSO BE A THREAT ACROSS THE COASTAL
WATERS...WITH LIGHTNING/HEAVY RAIN/GUSTY WINDS AND WATERSPOUTS ALL
POSSIBLE WITH ANY THUNDERSTORMS.
