SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
245 PM PST SUN MAR 7 2010

.SYNOPSIS...
COLD LOW PRESSURE SYSTEM EXITING OUT OF AREA TODAY...BUT WRAP AROUND
MOISTURE WILL CONTINUE TO BRING SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS
THROUGH EARLY EVENING. A COUPLE OF WEAK AND MOSTLY DRY FRONTAL SYSTEMS WILL
MOVE THROUGH THE AREA DURING THE NEXT FEW DAYS BRINGING GUSTY WINDS AND
A SMALL CHANCE OF PRECIPITATION. TEMPERATURES WILL REMAIN BELOW THE
SEASONAL NORMALS UNTIL MIDWEEK...THEN HIGH PRESSURE STARTS A WARMING TREND
LATER IN THE WEEK.

&&

.SHORT TERM (TODAY-WEDNESDAY)...
DOPPLER RADAR SHOWING INCREASING SHOWER ACTIVITY ACROSS THE FORECAST
AREA THIS AFTERNOON AS ATMOSPHERE CONTINUES TO DESTABILIZE. SPOTTER
JUST REPORTED THUNDERSTORM IN PEARBLOSSOM...AND WOULD EXPECT ISOLATED
THUNDERSTORM ACTIVITY FOR NEXT FEW HOURS...MAINLY ACROSS LOS ANGELES
COUNTY AND EASTERN VENTURA COUNTY. THESE AREAS CONTINUE TO BE THE
FOCUS FOR BEST RESIDUAL MOISTURE AND INSTABILITY. TAKING A QUICK GLANCE AT
18Z NAM GUIDANCE...STILL SHOWING A FAIRLY LARGE AREA OF 0 TO -2 LIFTED
INDICES WITH MAXIMUM K-INDEX VALUES OF AROUND 30. THIS INSTABILITY
NOT A SURPRISE SINCE THERE WAS SOME GOOD DAYTIME HEATING COMBINED
WITH COLD TEMPERATURES ALOFT (500 MB TEMPERATURES STILL AROUND -25
DEGREES CELSIUS). ALSO OF NOTE IS THE FAIRLY LARGE AREA OF CAPE VALUES
BETWEEN 500 AND 700 J/KG BEING PROJECTED ON THE 18Z NAM SOLUTION.

WITH THE NORTHERLY FLOW ALOFT...ANY STORMS THAT DEVELOP OVER THE MOUNTAINS
AND ANTELOPE VALLEY WILL HAVE THE POTENTIAL TO DRIFT INTO THE LA
BASIN. SINCE THERE IS FAIRLY STRONG WINDS ALOFT...IT DOES NOT APPEAR
THAT ANY STORMS WILL SIT IN ONE LOCATION FOR TOO LONG. NONETHELESS...
THERE WILL CERTAINLY BE THE POTENTIAL FOR BRIEF HEAVY DOWNPOURS...
AS WELL GUSTY WINDS AND SMALL HAIL WITH STORMS. THE BRIEF HEAVY DOWNPOURS
WILL TYPICALLY OCCUR IN A TIME FRAME OF 15 MINUTES OR LESS. WHILE
THERE IS NOT A LARGE ENOUGH THREAT TO ISSUE A FLASH FLOOD WATCH
FOR THE RECENT BURN AREAS...IT IS IMPORTANT TO REMEMBER THAT AN
ISOLATED THUNDERSTORM CAN ALWAYS BRING A THREAT OF MINOR DEBRIS
FLOW ISSUES. MOST OF THE SHOWER AND THUNDERSTORM THREAT SHOULD DIMINISH
AFTER SUNDOWN.

THE OTHER MAIN CONCERN FOR NEXT FEW DAYS WILL BE GUSTY WINDS. ALREADY
SEEING MARKED INCREASE IN WEST TO NORTHWEST WINDS BEHIND THIS FIRST
SYSTEM...WITH SOME AREAS APPROACHING ADVISORY LEVELS. MAIN CONCERN WILL
BE SBA COUNTY WHERE CURRENT SBA-SMX GRADIENT IS ALREADY AT -3.5 MB.
EVEN STRONGER UPPER LEVEL WIND SUPPORT AND COLD AIR WILL FOLLOW
TOMORROWS COLD FRONT...SETTING THE STAGE FOR AN EVEN MORE WIDESPREAD
AND STRONGER WIND EVENT MONDAY NIGHT INTO TUESDAY. DURING THIS TIME...
WOULD EXPECT SEVERAL WIND ADVISORIES TO BE ISSUED...WITH THE STRONGEST
WINDS EXPECTED IN THE MOUNTAINS AND ANTELOPE VALLEY WHERE WINDS COULD
GUST TO 50 MPH. THE STRONG WINDS ARE LIKELY TO PERSIST IN MANY AREAS
THROUGH TUESDAY NIGHT.

AS FAR AS THIS NEXT FRONTAL SYSTEM IS CONCERNED...LOOKS LIKE MAIN
CHANCE FOR SHOWERS WILL BE NORTH OF POINT CONCEPTION AND THE MOUNTAINS...
WHERE POPS ARE CURRENTLY IN THE 20 TO 40 PERCENT RANGE. ANY RAIN THAT
DOES FALL SHOULD BE LIGHT...GENERALLY UNDER .10 INCHES...EXCEPT LOCALLY
HIGHER AMOUNTS ACROSS NORTH FACING SLOPES. SNOW LEVELS WILL BE FALLING
QUICKLY MONDAY NIGHT...BOTTOMING OUT IN THE 2500 TO 3000 FOOT RANGE
ACROSS NORTH FACING SLOPES AND INTERIOR VALLEYS. AS A RESULT...THERE
IS THE STRONG POTENTIAL FOR SOME SNOW ISSUES ALONG INTERSTATE 5 NEAR
THE GRAPEVINE. DUE TO THE FAVORABLE UPSLOPE NORTHWEST FLOW...COULD
SEE 2 TO 4 INCHES OF SNOW ON THE NORTH FACING SLOPES. ALSO AT RISK FOR
SOME SNOW SHOWERS WOULD BE THE FOOTHILLS OF THE CUYAMA VALLEY AND
ANTELOPE VALLEY.

.LONG TERM (THU-SUN)...
BOTH THE EC AND THE GFS AGREE THAT THE EXTENDED PERIOD SHOULD BE
GENERALLY DRY WITH WARMER TEMPERATURES FOR THURSDAY AND FRIDAY. A
WEAK SYSTEM WILL MOVE THROUGH CENTRAL CALIFORNIA BY FRIDAY NIGHT...
BUT DOES NOT APPEAR THAT PRECIPITATION WILL WORK ITS WAY SOUTH INTO
OUR CWA.

&&

.AVIATION...07/1800Z.

MID/UPPER LEVEL TROUGH CENTERED EAST OF THE AREA WILL CONTINUE EAST
WHILE A MID/UPPER LEVEL TROUGH UPSTREAM APPROACHES. MODERATE UPPER
LEVEL NORTH WINDS WILL BECOME STRONG BY 08/00Z THEN MODERATE WEST
SOUTHWEST AFTER 08/09Z. MODERATE NORTH MID LEVEL WINDS WILL BECOME
LIGHT WEST BY 08/18Z. THERE IS A SLIGHT CHANCE OF THUNDERSTORMS THIS
AFTERNOON...WITH TOPS AROUND 35KFT...A MOVEMENT TO THE SOUTH
SOUTHEAST IS LIKELY. RELATIVE WEAK PRESSURE GRADIENT WILL
BECOME MODERATE ONSHORE THIS AFTERNOON THEN BECOME WEAK NORTHERLY
OVERNIGHT. FREEZING LEVEL WAS AROUND 6KFT THIS MORNING AND WILL
ASCEND TO AROUND 8KFT BY 08/12Z.

KLAX...IT IS LIKELY GUSTY ONSHORE LOW LEVEL WINDS WILL DIMINISH
AFTER 08/03Z. OTHERWISE THERE IS A CHANCE CIGS 024 WILL DEVELOP
AFTER 08/09Z AND PERSIST THROUGH 08/20Z.

KBUR...IT IS LIKELY GUSTY WEST LOW LEVEL WINDS WILL DIMINISH AFTER
08/03Z. OTHERWISE THERE IS A SLIGHT CHANCE OF LIGHT SHOWERS THIS
AFTERNOON AND A CHANCE CIGS AROUND 040 WILL DEVELOP BY 08/11Z

VIRTUALLY CERTAIN - 95-100%
VERY LIKELY       - 80-95%
LIKELY            - 60-80%
CHANCE            - 30-60%
VERY UNLIKELY     - 20% OR LESS
