SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
210 PM PST TUE FEB 15 2011

.SYNOPSIS...

A SERIES OF LOW PRESSURE SYSTEMS WILL MOVE ACROSS THE REGION THROUGH
SATURDAY CAUSING PERIODS OF RAIN AND LOW ELEVATION SNOW ALONG WITH
BELOW NORMAL TEMPERATURES. DRIER BUT COOL WEATHER IS EXPECTED SUNDAY
AND MONDAY.

&&

.SHORT TERM (TODAY-FRI)...THE FIRST STORM OF THE WEEK HAS MOVED EAST
OF THE AREA BUT STILL A FEW LINGERING SPRINKLES AND LIGHT SHOWERS
ACROSS LA/VTU COUNTIES THIS AFTERNOON. OUR NEXT COLD FRONT IS
APPROACHING THE BAY AREA THIS AFTERNOON AND IS EXPECTED TO MOVE INTO
SLO/SBA COUNTIES TONIGHT AND INTO VENTURA/LA COUNTIES WEDNESDAY
MORNING. THIS NEXT ONE HAS A LITTLE MORE PUNCH TO IT AND SHOULD
BRING MOST AREAS AT LEAST A QUARTER TO HALF INCH OF RAIN WITH IT BY
WEDNESDAY EVENING. DECENT SOUTHERLY FLOW WITH THE COLD FRONT WILL
ENHANCE PRECIP VALUES ACROSS THE SOUTH FACING MTN SLOPES AND
FOOTHILL AREAS WHERE AS MUCH AS AN INCH COULD FALL. SNOW LEVELS WILL
START OUT PRETTY HIGH DUE TO A DECENT WARM AIR SURGE AHEAD OF THE
FRONT, BUT WILL DROP RAPIDLY WEDNESDAY. AT THIS TIME FEEL SNOW
AMOUNTS WILL NOT EXCEED ADVISORY CRITERIA SO WILL JUST GO WITH A
WINTER WEATHER ADVISORY FOR THE VTU/LA MTNS STARTING LATE TONIGHT
AND RUNNING THROUGH WEDNESDAY EVENING.

GUSTY WINDS HAVE ALREADY DEVELOPED IN THE ANTELOPE VALLEY TODAY, AND
WHILE I DO EXPECT THESE WINDS TO DROP OFF SOMEWHAT OVERNIGHT THEY
WILL KICK UP AGAIN WEDNESDAY, ESPECIALLY IN THE AFTERNOON BEHIND THE
FRONT. WILL GO AHEAD WITH A WIND ADVISORY STARTING THIS AFTERNOON
AND KEEP IT GOING THROUGH WEDNESDAY EVENING DESPITE THE EXPECTED
FALL OFF IN THE WINDS LATER TONIGHT AND WED AM.

MODELS SHOW A LITTLE IMPULSE MOVING THROUGH THE AREA WEDNESDAY NIGHT
INTO THU MORNING, JUST ENOUGH TO MAINTAIN A THREAT OF SHOWERS ACROSS
THE AREA. SIGNIFICANT COLDER AIR WILL BE MOVING DURING THAT TIME,
LOWERING SNOW LEVELS TO AROUND 3000 FEET. PREVIOUSLY ISSUED WINTER
WEATHER ADVISORY MAY HAVE TO BE EXTENDED AND EXPANDED TO POSSIBLY
INCLUDE SBA COUNTY MTNS IF THE PRECIP BECOMES HEAVIER OR MORE
WIDESPREAD THAN ANTICIPATED. LIGHT SNOW COULD ALSO FALL IN PORTIONS
OF INTERIOR SLO COUNTY AS WELL AS THE HILLS AROUND THE CUYAMA VALLEY.

THERE WILL BE A LITTLE BIT OF A BREAK IN THE ACTIVITY THU AFTERNOON
THROUGH EARLY FRIDAY BEFORE OUR NEXT SYSTEM ARRIVES. THIS ONE
CERTAINLY LOOKS TO BE THE STRONGEST OF OUR STORMS THIS WEEK,
BRINGING PERIODS OF HEAVY RAIN AND SNOW TO THE AREA. TIMING STILL A
LITTLE UNCERTAIN AS THE FASTER ECMWF BRINGS THE FRONT THROUGH LA
COUNTY AS EARLY AS FRIDAY AFTERNOON WHILE THE SLOWER NAM/GFS
SOLUTIONS ARE A GOOD 6-12 HOURS BEHIND THAT. EITHER WAY, AMOUNTS
WITH THIS NEXT STORM ARE AT LEAST A NOTCH ABOVE THE WED STORM, WITH
AMOUNTS RANGING FROM .5-1.5" CST/VLYS AND 1.5-3" IN THE
FOOTHILLS/MTNS. SNOW LEVELS DO RISE AHEAD OF THE STORM BUT FALL
RAPIDLY FRIDAY NIGHT AND WE COULD SEE CLOSE TO A FOOT OF SNOW ACROSS
HIGHER ELEVATIONS. LIGHT ACCUMULATIONS EXPECTED TO ELEVATIONS AS LOW
AS 3000-3500 FEET FRIDAY NIGHT OR EARLY SATURDAY, RESULTING IN
SIGNIFICANT IMPACTS TO INTERSTATE 5 OVER THE GRAPEVINE.

.LONG TERM (SAT-TUE)...STEADY PRECIP SHOULD START TAPERING OFF
SATURDAY MORNING BUT A FAIR AMOUNT OF POST-FRONTAL SHOWERS ARE
EXPECTED THROUGH THE DAY, ESPECIALLY IN THE MTNS. LOW SNOW LEVELS
AGAIN WITH SNOW POSSIBLE OVER INTERSTATE 5 AND HIGHWAY 14 AS WELL AS
THE FOOTHILLS OF THE ANTELOPE VALLEY.

DRIER NORTHWEST FLOW EXPECTED TO DEVELOP BY SATURDAY NIGHT AND
SUNDAY WITH ANY PRECIP CONFINED MAINLY TO NORTH FACING MTN SLOPES.
HIGHS SUNDAY AND MONDAY SHOULD REBOUND A FEW DEGREES UNDER PARTLY
CLOUDY SKIES.

12Z GFS/ECMWF SHOWING ANOTHER COLD UPPER LOW DROPPING SOUTH ALONG
THE WEST COAST MONDAY INTO TUESDAY. THIS APPEARS TO BE TAKING MORE
OF A INLAND TRAJECTORY, BUT AT THIS TIME THERE IS JUST ENOUGH
MOISTURE WITH IT TO WARRANT AT LEAST A SLIGHT CHANCE OF SHOWERS
MONDAY NIGHT INTO TUESDAY. THIS SYSTEM IS EVEN COLDER THAN THE
FRI/SAT STORM WITH THICKNESSES FALLING TO THE HIGH 520S TUESDAY
MORNING. SO AT THE VERY LEAST IT WILL BE ON THE CHILLY SIDE. AND IT
LOOKS LIKE TEMPERATURES MOST OF NEXT WEEK WILL REMAIN BELOW NORMAL.

&&

.AVIATION...15/1800Z.
A FEED OF MOISTURE OUT OF THE SOUTHWEST WILL CONTINUE UNTIL
WEDNESDAY AFTERNOON WHEN A COLD FRONT IS SLATED TO SWEEP THROUGH THE
FORECAST AREA. THE RESULT OF THIS WEATHER PATTERN WILL BE MVFR TO
IFR CONDITIONS WITH OCCASIONAL LIGHT RAIN THROUGH TONIGHT AND SOME
MODERATE RAIN ASSOCIATED WITH THE COLD FRONTAL PASSAGE ON WEDNESDAY.
THERE IS GOOD CONFIDENCE IN THE FORECAST.

KLAX...GOOD CONFIDENCE IN THE 18Z TAF. MVFR TO IFR CONDITIONS
THROUGH WEDNESDAY WITH OCCASIONAL LIGHT TO MODERATE RAIN. THERE WILL
BE EAST WINDS APPROACHING 10 KNOTS WEDNESDAY MORNING.

KBUR...GOOD CONFIDENCE IN THE 18Z TAF. MVFR TO IFR CONDITIONS
THROUGH WEDNESDAY WITH OCCASIONAL LIGHT TO MODERATE RAIN.
