SIRARD

SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION...UPDATE
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
1005 AM PST THU JAN 11 2007

UPDATED AVIATION DISCUSSION AND ADVISORIES

.SHORT TERM...ONLY CHANGES MADE THIS MORNING WAS LOWERING POPS OVER
LA COUNTY TO SLIGHT CHANCE ON FRIDAY. WITH TROUGH MOVING
PROGRESSIVELY FASTER SKIES SHOULD CLEAR OUT QUICKER WITH THE
EXCEPTION OF THE USUAL NORTHERN SLOPES OF THE LA/VTU MOUNTAINS
THROUGH FRI EVENING WITH SNOW SHOWERS IMPACTING THE INTERSTATE 5
CORRIDOR. WITH GENERALLY CLEAR SKIES AND LESS MOISTURE ACROSS THE
REGION...CONFIDENCE REMAINS HIGH FOR VERY COLD TEMPS AFFECTING
SOUTHERN AND CENTRAL CALIFORNIA AS PREVIOUS DISCUSSION MENTIONS.

...FROM PREVIOUS DISCUSSION...

.THE MARINE LAYER HAS REDEVELOPED AND HAS DEEPENED RAPIDLY DURING
THE PAST 12 HOURS...NOW UP TO 5000 FEET...WITH CLDS PUSHING INTO AND
THRU THE CSTL SLOPES...AND TRYING TO SPREAD INTO THE ANTELOPE
VALLEY. GIVEN THE RAPID DEEPENING OF THE MARINE LAYER...THE SHARP
INCREASE IN ONSHORE GRADS...INCREASINGLY CYCLONIC FLOW THRU THE
ATMOSPHERE...AND A VORT LOBE APCHG FROM THE NORTHWEST...THERE IS THE
POSSIBILITY THAT SOME SCATTERED LIGHT RAIN OR SHOWERS COULD DEVELOP
JUST ABOUT ANYWHERE THIS MORNING...AT LEAST FROM THE CSTL SLOPES
WWD...AND CAN NOT RULE OUT SCATTERED SHOWERS THRU THE DAY. CERTAINLY
DO NOT XPCT ANYTHING HEAVY...AND MANY AREAS MAY REMAIN DRY...BUT THE
RISK IS STILL THERE TODAY. OTHERWISE...XPCT A GOOD DEAL OF CLOUDS
ACRS THE REGION TODAY. THERE WILL BE GUSTY WINDS...ESPECIALLY IN THE
MTNS AND DSRTS...AND WINDS COULD APCH ADVISORY LEVELS THIS
AFTERNOON. HAVE LEFT WINDS JUST BELOW ADVISORY LVLS...BUT THAT WILL
HAVE TO BE WATCHED CLOSELY TODAY. TODAY WILL BE ANOTHER DAY WITH
SIGNIFICANT COOLING...DOWN ANOTHER 10 DEGREES OR SO IN MANY
AREAS...AND EXPECT ONLY THE WARMER LOCATIONS ON THE COASTAL PLAIN
AND VLYS OF L.A. AND VTU COUNTIES TO REACH 60 DEGREES TODAY.

THE MODELS ARE IN MUCH BETTER AGREEMENT THIS MORNING...AND HAVE BEEN
FAIRLY CONSISTENT FOR THE PAST 3 RUNS OR SO. BOTH THE GFS AND THE
WRF SHOW THE CENTER OF AN EXTREMELY COLD UPPER LOW DROPPING SWD
THRU THE PAC NW TODAY AND TONIGHT...REACHING A POSITION NEAR RENO
VERY LATE TONIGHT...THEN SWINGING SEWD TO A POSITION TO THE W OF LAS
VEGAS BY LATE FRI AFTERNOON. THIS TRACK IS A BIT FARTHER INLAND THAN
SOME OF THE RUNS OF THE WRF HAD BEEN SHOWING...BUT IT IS FAIRLY
CLOSE TO THE TRACK SHOWN BY THE GFS THE LAST FEW RUNS. THEREFORE...
IT WILL BE STARVED FOR MSTR. HOWEVER...CRASHING HEIGHTS...INCREASING
INSTABILITY DUE TO SIGNIFICANT COOLING ALOFT...AND A STRONG VORT
LOBE DROPPING SWD TOWARD THE AREA SHOULD KEEP A THREAT OF SHOWERS
TONIGHT AND FRI. ENOUGH MSTR WILL LIKELY LINGER TO KEEP THE THREAT
GOING ACRS L.A. COUNTY INTO FRI EVENING. CAN NOT RULE OUT AN ISOLD
TSTM LATER TODAY THRU FRI...ESPECIALLY ACRS THE CSTL WATERS...AND
ANY TSTM COULD PRODUCE WATERSPOUTS AND SMALL HAIL. AT THIS TIME...IT
LOOKS LIKE THE BEST THREAT OF PRECIP AND THE HIGHEST TOTALS WILL BE
IN THE MTNS AND ACRS L.A. COUNTY... BUT PRECIP AMOUNTS WILL BE ON
THE LIGHT SIDE...GENERALLY ONE QUARTER OF AN INCH OR LESS...WITH
LOCALLY HIGHER AMOUNTS POSSIBLE IN THE MTNS. HAVE DECIDED TO KEEP
POPS IN THE CHANCE CATEGORY...SINCE SHOWERS WILL LIKELY BE SCATTERED
IN NATURE...AND NOT ALL AREAS WILL RECEIVE MEASURABLE PRECIP.

TEMPS AT 850 AND 950 MB WILL CONT TO DROP QUICKLY LATER TODAY AND
TONIGHT...AND SNOW LEVELS WILL LIKELY DROP TO BETWEEN 1500 AND
2000 FEET BY LATE TONIGHT...AND CONT THAT WAY INTO FRIDAY EVENING.
THIS WOULD BRING SNOW LOCALLY INTO THE FOOTHILLS AROUND THE LOCAL
VALLEYS. THERE COULD LOCALLY BE SMALL ACCUMULATIONS OF SNOW IN THE
FOOTHILLS ABOVE THE VALLEYS AND IN THE ANTELOPE AND CUYAMA
VLYS...BUT PROBABLY LESS THAN AN INCH IN MOST AREA. A FEW INCHES
MAY FALL IN THE MOUNTAINS...AND SNOW ADVISORIES...OR SNOW AND
BLOWING SNOW ADVISORIES MAY HAVE TO BE CONSIDERED...DEPENDING UPON
HOW WDSPRD PRECIPITATION BECOMES. FRI WILL BE A VERY COLD DAY
ACRS THE FCST AREA...WITH SOME VLY LOCATIONS REMAINING IN THE
40S. ALL LOCATIONS IN SOUTHWESTERN CALIFORNIA WILL FAIL TO RISE
OUT OF THE 50S ON FRIDAY.

BESIDE THE VERY LOW SNOW LEVELS...THE OTHER IMPRESSIVE ASPECT OF
THIS SYSTEM WILL BE THE COLD. THE LATEST RUNS SUGGEST EVER SO
SLIGHTLY LESS COLD CONDITIONS THAN PREVIOUS RUNS AS THICKNESSES
AND TEMPS AT 850 AND 950 MB DO NOT GET QUITE AS LOW AS ON PREVIOUS
RUNS FRI NIGHT/SAT MORNING...AND THESE VALUES MODERATE A BIT
SOONER SINCE THE SYSTEM IS MORE PROGRESSIVE. HOWEVER...IT STILL
LOOKS LIKE TWO VERY COLD NIGHTS ACRS THE AREA FRI NIGHT AND SAT
NIGHT...WITH RECORD OR NEAR RECORD LOW TEMPERATURES POSSIBLE IN MANY
LOCATIONS. HARD FREEZES ARE POSSIBLE IN ALL AREAS WITH THE EXCEPTION
OF THE L.A. COUNTY CST AND CATALINA ISLAND. FREEZE WATCHES HAVE
BEEN ISSUED FOR THE L.A. AND VTU COUNTY VLYS...THE VENTURA COUNTY
CST...THE SBA COUNTY S CST...AND THE SANTA MONICA MTNS. SINCE CSTL
SXNS OF SLO AND SBA COUNTIES HAVE ALREADY EXPERIENCED A FEW NIGHTS
OF TEMPS IN THE 20S...THOSE AREAS WERE NOT INCLUDED IN THE WATCH.

ON FRIDAY NIGHT...VERY STRONG COLD ADVECTION...AND IMPRESSIVELY LOW
THICKNESS VALUES AND 850/950 MB TEMPS SHOULD ALLOW IT TO GET QUITE
COLD ACRS MUCH OF THE AREA. ONE LIMITING FACTOR FOR LOW TEMPS FRI
NIGHT WILL BE ANY LINGERING CLOUDINESS...WHICH WILL LIKELY KEEP
TEMPS UP SLIGHTLY ACRS L.A. COUNTY. HOWEVER...IF IT CLEARS EARLY FRI
EVENING...A SOLUTION TOWARD WHICH THE LATEST MODELS HAVE
TRENDED...THIS MAY NOT BE MUCH OF ANN ISSUE. THE OTHER FACTOR WILL
BE THE WIND. AT THIS POINT...DO NOT XPCT WDSPRD STRONG WINDS...BUT
WHERE WINDS STAY UP...TEMPS WILL ALSO STAY UP A BIT. ON THE OTHER
HAND...AREAS OF GUSTY WINDS IN THE MTNS LATE TONIGHT THROUGH
SATURDAY MORNING WILL PRODUCER VERY LOW TO DANGEROUS WIND CHILL
VALUES...WITH APPARENT TEMPERATURES FEELING LIKE ZERO TO TEN DEGREES
BELOW ZERO AT TIMES IN THE MTNS. PEOPLE DOING OUTDOOR ACTIVITIES IN
THE MTNS...INCLUDING SKIING AND SNOWBOARDING SHOULD BE PREPARED FOR
BITTERLY COLD WIND CHILL VALUES. ALTHOUGH HGTS/THICKNESSES AND TEMPS
AT 850 WILL BEGIN TO RISE SAT...LOW LVL COLD AIR WILL REMAIN IN
PLACE...AND IT WILL BE DRIER SAT NIGHT. THEREFORE...LOW TEMPS WILL
BE AS COLD OR POSSIBLY COLDER IN MOST AREAS SAT NIGHT. WIND SHELTER
LOCATIONS IN THE L.A. AND VTU COUNTY VLYS COULD DROP INTO THE 20S...
WITH TEMPS IN THE MID TO UPPER 20S POSSIBLE IN COLDER LOCATIONS OF
THE VTU COUNTY CST AND THE SANTA BARBARA COUNTY S CST. LOWS WILL
DROP INTO THE TEENS IN THE ANTELOPE VLY...AND THE INTERIOR VLYS OF
SLO AND SBA COUNTY. ONLY THE L.A. COUNTY CSTL PLAIN IS LIKELY TO
REMAIN MUCH ABOVE FREEZING...BUT EVEN THERE...LOCAL FROST IS
POSSIBLE.

.LONG TERM...HGTS WILL RISE ACRS THE AREA ON SUNDAY...SO TEMPS WILL
LIKELY BE ON THE RISE. THE GFS SHOWS ANOTHER VIGOROUS UPPER DROPPING
SWD THRU THE GREAT BASIN INTO THE FOUR CORNERS AREA SUN NIGHT AND
MONDAY...PUTTING THE BRAKES ON HEIGHT RISES AND BRINGING A RETURN
TO OFFSHORE FLOW AND LOCALLY GUSTY WINDS. LOOKS LIKE OFFSHORE GRADS
PEAK MON NIGHT/TUE...AND WIND ADVISORIES/WARNINGS MAY BE REQUIRED
FOR SOME AREAS. YET AGAIN...CONDITIONS MAY APCH CRITICAL VALUES FOR
FIRE DANGER. BEYOND TUE...LOOKS LIKE OFFSHORE GRADS WILL WKN AS
AN UPPER LOW PUSHES INTO NRN CA...BUT MODELS HAVE BEEN QUITE
INCONSISTENT WITH THE UPPER PATTERN FOR NEXT WEEK...SO CONFIDENCE
IN THE DETAILS IS LOW.

&&

.AVIATION...
NORTH OF POINT CONCEPTION OVERCAST SKIES SHOULD STAY ABOVE MVFR CAT
THROUGH THIS EVENING. GUSTY NW WINDS ARE LIKELY AFTER 20Z AT KSMX
AND KSBP.

SOUTH OF POINT CONCEPTION...DEEPENING MARINE LAYER UP TO 050. THERE
IS STILL A CHANCE FOR SOME DRIZZLE THIS MORNING...BUT WILL NOT BE
WIDESPREAD. COASTAL AND VALLEY AIRFIELDS WILL SEE PERIODS OF MVFR
CIGS ABOVE 020...BUT WILL BE TEMPORARY AND MOSTLY BE ABOVE 035. RAIN
CHANCES SEEM LESS AND LESS LIKELY WITH EACH PASSING HOUR. THIS
AFTERNOONS CHANCES ARE NOT WORTH MENTIONING IN THE TAF...BUT THERE
IS STILL AN OUTSIDE SHOT OVERNIGHT. WINDS WILL PICKUP LATER IN THE
EVENING AND INTO FRI MORNING.

KLAX WILL BE OVERCAST VFR THROUGH THIS EVENING...WITH AN HOUR OR TWO
POSSIBLE OF CIGS NEAR 025 BETWEEN 19Z-23Z. WESTERLY WIND SHOULD TAKE
HOLD AFTER 20-21Z. WINDS WILL THEN PICKUP THIS EVENING THROUGH FRI
MORNING OUT OF THE WEST...WITH GUSTS NEAR 20 KT VERY POSSIBLE AROUND
SUNRISE AT KLAX.
