SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
245 AM PDT THU APR 7 2011

.SYNOPSIS...

A VERY COLD LOW PRESSURE SYSTEM WILL BRING UNSETTLED WEATHER TO THE
AREA TODAY THROUGH SATURDAY MORNING. GUSTY WINDS AND A CHANCE OF
SHOWERS AND A SLIGHT CHANCE OF THUNDERSTORMS ARE POSSIBLE THURSDAY
THROUGH FRIDAY NIGHT. SNOW LEVELS COULD FALL TO 2000 FEET. A GRADUAL
WARMING IS EXPECTED SATURDAY AFTERNOON THROUGH MIDWEEK.

&&

.SHORT TERM (TODAY-SAT)...AN UNSETTLED WEATHER PATTERN WILL AFFECT
THE FORECAST AREA TODAY THROUGH EARLY SATURDAY MORNING. A VERY COLD
UPPER LVL LOW WILL CONTINUE TO PUSH SOUTH FROM OREGON INTO CENTRAL
CALIFORNIA THIS AFTERNOON. THE TRAJECTORY OF THIS UPPER LOW WILL
CONTINUE TO STAY OVER LAND...THEREFORE NOT MUCH IN THE WAY OF
MOISTURE TO TAP INTO. SCATTERED SHOWERS WILL INCREASE THIS MORNING
ACROSS THE CENTRAL COAST WITH LIGHT SHOWER ACTIVITY EXPECTED AS A
COLD FRONT APPROACHES SLO COUNTY THIS MORNING. MEANWHILE... STRONG
GUSTY WINDS ACROSS THE OUTER WATERS HAVE HELPED A CATALINA EDDY TO
DEVELOP THIS MORNING. THE CYCLONIC FLOW WITH THIS EDDY HAS CAUSED A
DEEP MARINE LAYER TO FORM AND WILL DEEPEN TO AROUND 4000 FT AND
SPREAD ACROSS THE LA/VTU COAST AND VALLEYS TO THE COASTAL SLOPES OF
THE MOUNTAINS AFTER SUNRISE. THERE WILL BE ENOUGH SW FLOW ALOFT TO
HELP CAUSE SOME LIFT AND BRING AREAS OF DRIZZLE OR LIGHT SHOWERS TO
LA/VTU COUNTIES WEST OF THE MOUNTAINS. BEST RAINFALL TOTALS WITH
THIS DEEP MARINE LAYER WILL AFFECT THE ELEVATED VALLEY FOOTHILLS.

EXPECT SKIES TO REMAIN CLOUDY IN MOST LOCATIONS TODAY. AS THIS
FRONTAL BOUNDARY FROM THE NORTH SLOWLY PUSHES SOUTH INTO SLO/SBA
COUNTIES THIS MORNING...EXPECT RAINFALL AMOUNTS TO BE AROUND ONE
QUARTER OF AN INCH OR LESS ACROSS SLO/SBA COUNTIES THROUGH THIS
EVENING WITH NW FLOW ALOFT. AS THE FRONTAL BOUNDARY REACHES LA
COUNTY LATER THIS AFTERNOON...SW CYCLONIC FLOW ALOFT WILL HELP TO
ENHANCE RAINFALL TOTALS. ALTHOUGH RAINFALL SHOULD REMAIN LIGHT
OVERALL...SOME MODERATE SHOWERS SHOULD INCREASE LATE THIS AFTERNOON
INTO THIS EVENING...ESPECIALLY ACROSS EASTERN LA COUNTY AS A LEFT
FRONT QUAD OF A 120KT JET CORE PUSHES ACROSS LA COUNTY CAUSING
ADDITIONAL LIFT AND DIVERGENCE ALOFT.

IN REGARDS TO WINDS...EXPECT VERY WINDY CONDITIONS AHEAD OF THE
FRONT ACROSS THE LA/VTU COUNTY MOUNTAINS AS WELL AS THE ANTELOPE
VALLEY TODAY. 25 TO 35 MPH WITH GUSTS TO 50 MPH CAN BE EXPECTED. AS
THE FRONT PUSHES THROUGH THE CENTRAL COAST THIS AFTERNOON...NW WINDS
WILL DEVELOP WITH GUSTS TO 35 MPH. THERE WILL ALSO BE VERY GUSTY
WESTERLY WINDS ACROSS THE COASTAL AREAS OF LA AND VTU COUNTIES THIS
AFTERNOON THROUGH THIS EVENING WITH GUSTS TO 40 MPH
POSSIBLE...ESPECIALLY NEAR THE COAST. THERE ARE WIND ADVISORIES ALSO
FOR THE VENTURA COUNTY VALLEYS WITH GUSTS TO 35 MPH. FOR NOW...HAVE
LEFT THE LA COUNTY VALLEYS OUT OF THE ADVISORIES...BUT SHOULD STILL
EXPERIENCE WESTERLY WINDS TO 25 MPH. WINDS WILL BEGIN TO DIMINISH
LATER THIS EVENING.

BY FRIDAY MORNING THE UPPER LOW WILL BE DIRECTLY OVER SOUTHERN AND
CENTRAL CALIFORNIA. AGAIN...DUE TO THE OVERLAND TRAJECTORY OF THIS
LOW...MOISTURE TAP WILL BE LIMITED ACROSS THE REGION.
HOWEVER...THICKNESS LVLS WILL HAVE LOWERED TO BETWEEN 528-530 DM.
THIS WOULD TRANSLATE TO SNOW LEVELS LOWERING TO AROUND 2200-2500 FT
BY FRIDAY MORNING. WITH THE LOW DIRECTLY OVERHEAD ON FRIDAY...THE
ATMOSPHERE WILL BECOME POTENTIALLY UNSTABLE. 500 MB TEMPS WILL BE
AROUND -34 DEGREES CELSIUS DURING THE PEAK HEATING OF THE AFTERNOON.
WITH ANY HEATING AT THE SURFACE BETWEEN THE PARTLY CLOUDY
SKIES...THE ATMOSPHERE WILL DESTABILIZE BRINGING A SLIGHT CHANCE OF
THUNDERSTORMS TO THE REGION. THUNDERSTORMS COULD DEVELOP JUST ABOUT
ANYWHERE ACROSS THE COASTAL WATERS AND MAINLAND. RAINFALL TOTALS
WILL VARY WIDELY DUE TO THE NATURE OF THUNDERSTORM POTENTIAL FOR
FRIDAY. FOR LOS ANGELES COUNTY...EXPECT ANYWHERE FROM A QUARTER INCH
OF RAIN TO AS HIGH AS THREE QUARTERS TO AN INCH POSSIBLE WITH
STRONGEST THUNDERSTORMS.

SNOW SHOWERS COULD IMPACT INTERSTATE 5 NEAR THE GRAPEVINE AS EARLY
AS TONIGHT...WITH AN EVEN HIGHER PROBABILITY BY FRIDAY
MORNING...WHEN SNOW LEVELS ARE EXPECTED TO FALL AS LOW AS 2000 FEET.
SUCH LOW SNOW LEVELS COULD BRING THE THREAT OF SNOW SHOWERS TO THE
CUYAMA AND ANTELOPE VALLEY...AS WELL AS HIGHWAY 14 THROUGH THE
SOLEDAD CANYON. HOWEVER...LITTLE OR NO SNOW ACCUMULATIONS ARE
EXPECTED FOR THESE AREAS. FOR THE MOUNTAINS...LOCAL SNOW
ACCUMULATIONS OF 1 TO 3 INCHES CAN BE EXPECTED. DUE TO THE
CONVECTIVE NATURE OF THIS SYSTEM...RAINFALL AMOUNTS ARE EXPECTED TO
BE HIGHLY VARIABLE. HOWEVER...MANY COASTAL AND VALLEY AREAS ARE
EXPECTED TO RECEIVE LESS THAN ONE THIRD OF AN INCH...EXCEPT LOCAL
AMOUNTS OVER ONE HALF INCH TO THREE QUARTERS OF AN INCH NEAR
THUNDERSTORMS. ON FRIDAY...HIGH TEMPERATURES ARE EXPECTED TO BE WELL
BELOW NORMAL...WITH POTENTIAL FROST CONCERNS FRIDAY NIGHT ACROSS
COLDEST INTERIOR VALLEYS.

BY SATURDAY...THERE COULD BE SOME LINGERING SHOWERS ACROSS EASTERN
LA COUNTY...ESPECIALLY THE SAN GABRIEL MOUNTAIN RANGE AND THE
NORTHERN SLOPES OF OF LA/VTU/SBA COUNTY MOUNTAINS. SNOW LEVELS WILL
BEGIN TO RISE TO AROUND 4000 TO 4500 FT. SKIES SHOULD REMAIN PARTLY
CLOUDY FOR THE MOST PART ON SATURDAY...WITH THE MOUNTAINS LIKELY
REMAINING MOSTLY CLOUDY. TEMPS WILL REBOUND A BIT BUT CONTINUE TO
REMAIN WELL BELOW NORMAL FOR THIS TIME OF YEAR.

.LONG TERM (SUN-WED)...
BY SUNDAY...THE UPPER LOW QUICKLY PUSHES INTO THE FOUR CORNERS
REGION BRINGING A WEAK RIDGE ACROSS THE AREA. TEMPS WILL BEGIN TO
REBOUND BY SUNDAY WITH MOST AREAS REMAINING IN THE MID TO UPPER 60S.
A SLOW WARMING TREND WILL CONTINUE ON MONDAY. A WEAK SHORTWAVE
SHOULD PUSH THROUGH THE CWA ON TUE BUT NO RAIN IS EXPECTED. POSSIBLE
LATE NIGHT THROUGH MORNING LOW CLOUDS WILL BE POSSIBLE. TEMPS SHOULD
BE SIMILAR TO MONDAY. BY WEDNESDAY...HIGH PRESSURE BUILDS IN ONCE
AGAIN WITH TEMPS WARMING INTO THE LOWER TO MID 70S IN MANY
LOCATIONS.
