...STRONG AND LOCALLY DAMAGING NORTH TO NORTHEAST WINDS ACROSS
PORTIONS OF SOUTHWEST CALIFORNIA TODAY...

.A COLD UPPER LEVEL LOW PRESSURE SYSTEM OVER SOUTHEAST
CALIFORNIA HAS BROUGHT STRONG UPPER LEVEL NORTH TO NORTHEAST WINDS
TO THE AREA. THESE STRONG WINDS WILL LIKELY TRANSLATE DOWN TO THE
SURFACE ACROSS PORTIONS OF LOS ANGELES AND VENTURA COUNTIES. THE
STRONGEST WINDS WILL BE FOCUSED ACROSS THE LOS ANGELES COUNTY
MOUNTAINS...AS WELL AS THE FOOTHILLS OF THE SAN GABRIEL VALLEY AND
SAN FERNANDO VALLEY...WHERE DAMAGING WIND GUSTS AROUND 60 MPH ARE
LIKELY. THESE CONDITIONS WILL LIKELY CREATE SEVERAL MOUNTAIN WAVES
WHICH COULD BRING STRONG AND SUDDEN WIND GUSTS ACROSS PORTIONS OF
THE LOS ANGELES BASIN THAT DO NOT NORMALLY SEE STRONG OFFSHORE
WINDS. DOWNED TREES AND POWER LINES ALONG WITH POWER OUTAGES WILL
BE LIKELY ACROSS PORTIONS OF THE LOS ANGELES BASIN.

THE WINDS WILL COMBINE WITH SCATTERED SNOW SHOWERS IN THE
MOUNTAINS TO PRODUCE HAZARDOUS DRIVING CONDITIONS. THE SNOW AND
BLOWING SNOW WILL LIKELY AFFECT INTERSTATE 5 NEAR THE GRAPEVINE.

SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
830 PM PST SUN JAN 6 2013

...STRONG WINDS DEVELOPING ACROSS PORTIONS OF LOS ANGELES BASIN
   OVERNIGHT INTO MONDAY...

.SYNOPSIS...
THE LOW PRESSURE SYSTEM WILL EXIT THE REGION TONIGHT...WITH CONTINUED
SNOW SHOWER THREAT IN THE MOUNTAINS. STRENGTHENING NORTH TO NORTHEAST
WINDS WITH ISOLATED DAMAGING WIND GUSTS ACROSS THE SOUTHLAND OVERNIGHT
INTO MONDAY IN THE WAKE OF THIS SYSTEM. ANOTHER LOW PRESSURE SYSTEM WILL
BRING A THREAT OF RAIN AND SNOW SHOWERS THURSDAY AND FRIDAY.

&&

.SHORT TERM (TONIGHT-WED)...
COLD UPPER LEVEL LOW PRESSURE SYSTEM CURRENTLY CENTERED OVER THE
MOJAVE DESERT IS FORECASTED TO TRACK SOUTHWARD AND BECOME CENTERED
IN IMPERIAL COUNTY BY EARLY MONDAY MORNING. THE TRACK OF THIS SYSTEM
IS SETTING UP FOR A SIGNIFICANT WIND EVENT FOR SOUTHERN CALIFORNIA...
ESPECIALLY FOR LOS ANGELES COUNTY AND POINTS SOUTH AND EAST. LATEST
00Z NAM AND GFS SOLUTIONS IN GOOD AGREEMENT ON TRACK OF UPPER LOW
BRINGING INCREASED CONFIDENCE IN THIS WIND EVENT. DUE TO PROXIMITY
OF UPPER LOW POSITION...THE STRONGEST WINDS ALOFT WILL BE FOCUSED
OVER LOS ANGELES COUNTY...WITH A 120 KNOT JET CORE EXPECTED TO
SWEEP ACROSS THE AREA EARLY MONDAY MORNING. PROJECTED WINDS AND
SUBSIDENCE BETWEEN 850-700 MB ARE ALSO IMPRESSIVE WITH A SOLID
AREA OF 40-50 KNOT WIND SPEEDS. THIS TYPE OF PATTERN SETUP IS
FAVORABLE FOR MOUNTAIN WAVE WIND CONDITIONS WHICH CAN BRING SUDDEN
AND LOCALIZED STRONG WIND GUSTS...INCLUDING AREAS THAT DO NOT TYPICALLY
SEE STRONG OFFSHORE WINDS. LATEST 00Z NAM AND 18Z HIGH RESOLUTION
WRF SOLUTIONS FOCUSING STRONGEST WINDS ACROSS THE SAN GABRIEL
MOUNTAINS...SANTA MONICA MOUNTAINS...SANTA CLARITA VALLEY...AND FOOTHILLS
OF THE SAN GABRIEL VALLEY AND SAN FERNANDO VALLEY. THIS SEEMS VERY
REASONABLE BASED ON THIS UPPER LEVEL PATTERN.

WHILE THIS PATTERN HAS SOME RESEMBLANCE TO THE VERY STRONG PASADENA WIND
EVENT OF 2011...THE UPPER LEVEL WIND SUPPORT AND SUBSIDENCE ARE NOT AS
STRONG. NONETHELESS...WE WILL LIKELY SEE STRONG WIND ADVISORY GUSTS IN
THE 40 TO 50 MPH RANGE ACROSS MANY PORTIONS OF OF LOS ANGELES COUNTY...WITH
ISOLATED DAMAGING GUSTS TO 60 MPH IN THE MOUNTAINS AND FOOTHILLS. WINDS THIS
STRONG WILL BE CAPABLE OF DOWNING TREES AND POWER LINES...WHILE CAUSING POWER
OUTAGES. POPULATED AREAS MOST VULNERABLE TO THESE STRONG WINDS INCLUDE
THE FOOTHILL COMMUNITIES NEAR INTERSTATE 210 EXTENDING FROM SYLMAR
EASTWARD THROUGH LA CRESCENTA TO THE SAN BERNARDINO COUNTY LINE. FOR
NOW...HAVE BLANKETED MUCH OF LOS ANGELES AND VENTURA COUNTIES UNDER
STRONG WIND ADVISORIES PER COORDINATION WITH SAN DIEGO...WITH MENTION
OF ISOLATED DAMAGING GUSTS TO 60 MPH IN THE MOUNTAINS AND FOOTHILLS WHERE
STRONGER MOUNTAIN WAVE CONDITIONS OCCUR. THESE AREAS MAY NEED TO BE UPGRADED
TO HIGH WIND WARNINGS WITH LATER SHIFTS IF DAMAGING WIND GUSTS BECOME MORE
WIDESPREAD.

OTHER AREA OF CONCERN TONIGHT WILL CONTINUE TO BE THREAT OF SNOW SHOWERS
ACROSS THE INTERIOR SLOPES OF THE MOUNTAINS. WITH SNOW LEVELS EXPECTED TO
LOWER TO 3000 FEET...AREAS ALONG INTERSTATE 5 NEAR THE GRAPEVINE COULD
BE IMPACTED BY WINTER WEATHER DRIVING CONDITIONS. ANY ACCUMULATIONS
ARE EXPECTED TO BE UNDER 3 INCHES.

*** FROM PREVIOUS DISCUSSION ***

FOR THE BALANCE OF MONDAY...AND CONTINUING THROUGH WEDNESDAY...DRY
CONDITIONS WILL PREVAIL AS A RIDGE BUILDS ACROSS THE WEST COAST
MONDAY/TUESDAY...BEFORE GETTING FLATTENED A BIT ON WEDNESDAY AS NEXT
SYSTEM APPROACHES. IN ADDITION...SOME AMOUNT OF NORTH TO NORTHEAST
FLOW WILL CONTINUE ACROSS THE AREA THROUGH THE PERIOD. SO...WILL
EXPECT SKIES TO REMAIN MOSTLY CLEAR THROUGH WEDNESDAY...ALTHOUGH
SOME STRATUS MAY DEVELOP WEDNESDAY MORNING ACROSS THE LOS ANGELES
COUNTY COAST. AS FOR TEMPS...A WARMING TREND WILL PREVAIL THROUGH
TUESDAY...WITH SOME COOLING ON WEDNESDAY.

.LONG TERM (THU-SUN)...
FOR THE EXTENDED...12Z MODELS ARE IN GOOD AGREEMENT THROUGH
SATURDAY...THEN DIVERGE NOTICEABLY ON SUNDAY. FOR THURSDAY/FRIDAY
MAIN FOCUS WILL BE AN UPPER TROUGH FORECAST TO MOVE ACROSS THE
PACIFIC NORTHWEST AND INTO THE GREAT BASIN. GIVEN THE INLAND TRACK
OF THIS TROUGH...DO NOT ANTICIPATE A SIGNIFICANT PRECIPITATION
EVENT. HOWEVER...THERE WILL BE A GOOD CHANCE OF SHOWERS THURSDAY
INTO FRIDAY MORNING...SO WILL KEEP CURRENT CHANCE POPS IN THE
FORECAST. DOES APPEAR TO BE A GOOD BIT OF COLD AIR ASSOCIATED WITH
THIS TROUGH...AND SNOW LEVELS DROP VERY LOW THURSDAY NIGHT (AROUND
3000 FEET).

DURING THE DAY ON FRIDAY...THE SHOWER THREAT SHOULD END WITH DRY
CONDITIONS CONTINUING THROUGH SATURDAY. HOWEVER...THERE WILL BE THE
POTENTIAL FOR ANOTHER ROUND OF GUSTY NORTH TO NORTHEAST WINDS
THROUGH THE PERIOD.

ON SUNDAY...MODELS DIFFER NOTICEABLY. THE GFS KEEPS THE AREA UNDER A
DRY NORTHERLY FLOW DURING THE DAY. CONVERSELY...THE ECMWF DROPS
ANOTHER LOW SOUTH ACROSS THE STATE...RESULTING IN THE POTENTIAL FOR
ANOTHER SHOT OF PRECIPITATION WITH VERY LOW SNOW LEVELS. GIVEN THE
MODEL DIFFERENCES...WILL KEEP THE FORECAST DRY FOR NOW AND HOPE FOR
BETTER MODEL CONSENSUS IN THE NEXT FEW DAYS.

&&

.AVIATION...06/2350Z.
COLD UPPER LEVEL LOW PRESSURE SYSTEM WILL CONTINUE TO GENERATE
SCATTERED SHOWERS ACROSS FORECAST AREA THROUGH EARLY EVENING...MAINLY
LOS ANGELES COUNTY AND INTERIOR SLOPES. SLIGHT CHANCE OF A THUNDERSTORM
TIL SUNDOWN. FREEZING LEVEL AROUND 4000 FEET. GUSTY NORTHERLY WINDS
WILL DEVELOP TONIGHT BEHIND THE SYSTEM...WITH THE POTENTIAL FOR
STRONG UDDFS AND LLWS IN FAVORED LOCATIONS.

KLAX...CHANCE CIGS 030 -SHRA TIL 03Z. GUSTY NORTHWEST WINDS
DEVELOPING WILL SHIFT TO NORTHERLY BY MIDNIGHT. CHANCE FOR NORTHERLY
WINDS TO GUST ABOVE 20 KNOTS TONIGHT...WITH ALSO A POSSIBILITY OF
LLWS.

KBUR...CHANCE CIGS 030 -SHRA TIL 03Z. GUSTY NORTHWEST WINDS
DEVELOPING THIS EVENING WILL SHIFT TO NORTHERLY BY MIDNIGHT. CHANCE
FOR NORTHERLY WINDS TO GUST TO AROUND 25 KNOTS TONIGHT...WITH POTENTIAL
FOR STRONG UDDFS AND LLWS.
