.SHORT TERM...(TODAY-SUN)
IN THE WAKE OF THE COLD FRONT THAT MOVED THROUGH
YESTERDAY...SCATTERED SHOWERS CONTINUE TO OCCUR ACROSS MAINLY SLO
AND SBA COUNTIES THIS MORNING. VERY TYPICAL WITH NW FLOW. RADAR
ECHOES LOOK FAIRLY IMPRESSIVE...BUT WITH COLD TEMPS ACROSS THE
AREA...THERE IS SOME BRIGHT-BANDING WITH RADAR RETURNS. ESPECIALLY
VANDENBERG. THERE HAS BEEN UP TO AN ADDITIONAL ONE THIRD OF AN INCH
OVER RANDOM AREAS OF BOTH SLO AND SBA COUNTIES OVERNIGHT. AS COLD
POOL BEGINS TO MOVE FARTHER EAST LATER THIS MORNING...THINKING THAT
SHOWERS WILL BECOME MORE ISOLATED....EXCEPT FOR THE NORTH FACING
SLOPES OF THE LA/VTU MOUNTAINS LATER TODAY WHERE AN ADDITIONAL SNOW
ACCUMULATION OF 2 INCHES WILL BE POSSIBLE THIS MORNING...THEN TAPER
OFF BY THE AFTERNOON HOURS. SKIES SHOULD REMAIN PARTLY CLOUDY WITH
RESIDUAL MOISTURE STILL IN THE AREA AND WITH THE HEATING OF THE DAY.
I TOOK OUT ISOLATED THUNDERSTORM WORDING...EXCEPT FOR THE LA/VTU/SBA
MOUNTAINS TODAY. TEMPS SHOULD BE VERY SIMILAR TO YESTERDAY...MAYBE A
COUPLE DEGREES OF WARMING WITH LESS CLOUD COVERAGE. THERE WILL BE
GUSTY NW WINDS ACROSS PORTIONS OF THE FORECAST AREA. THE ANTELOPE
VALLEY WILL BE NEAR WIND ADVISORY CONDITIONS WITH NORTHWEST WINDS 25
TO 35 MPH. DAY SHIFT WILL MONITOR CLOSELY. WINDS WILL BEGIN TO SHIFT
OUT OF THE NORTH TONIGHT AND BRING SOME GUSTY WINDS TO THE LA/VTU
AND SBA MOUNTAINS THIS EVENING. THE STRONGEST WINDS WILL OCCUR
ACROSS THE I-5 CORRIDOR WITH SUSTAINED WINDS BETWEEN 25 TO 35 MPH
WITH LOCAL GUSTS TO 50 MPH. WINDS SHOULD STAY BELOW WIND ADVISORY
LEVEL BUT WILL HAVE TO BE MONITORED.
SKIES SHOULD BE MOSTLY SUNNY ON SATURDAY WITH A FEW DEGREES OF
HEATING ACROSS THE FORECAST AREA BUT STILL SLIGHTLY COOLER THAN
NORMAL FOR THIS TIME OF YEAR. BROAD NW FLOW ALOFT WILL PREVAIL
ACROSS THE REGION. A QUICK AND WEAK SHORTWAVE WILL APPROACH SLO
COUNTY ON SUNDAY. ADDED 20 PERCENT POPS. MORE FOR COORDINATION WITH
MONTEREY THEN WITH CONFIDENCE OF ANY SHOWERS IN SLO COUNTY. NOT
EXPECTING MUCH IN PRECIP AS THIS SYSTEM WILL BE FAST MOVING THROUGH.
MOST LOCATIONS N OF POINT CONCEPTION SHOULD RECEIVE LESS THAN ONE
TENTH OF AN INCH IF ANY. TEMPS WILL COOL A FEW DEGREES AS HEIGHTS
AND THICKNESS DROP SLIGHTLY AND STRONGER ONSHORE FLOW.

.LONG TERM...(MON-THU)
BROAD UPPER NW FLOW WILL PREVAIL MON WITH A WEAK SHORTWAVE
APPROACHING THE CENTRAL COAST LATE MON. ADDED 20 PERCENT POPS TO
COORDINATE WITH MONTEREY NWS...BUT NOT THAT CONFIDENT. MAYBE A
SPRINKLE OR TWO. A BETTER CHANCE OF PRECIP WILL AFFECT THE CENTRAL
COAST LATE TUE AS ANOTHER SHORTWAVE APPROACHES. STILL NOT IMPRESSIVE
AS IT MOVES THROUGH THE AREA QUICKLY. FRONT MIGHT HOLD TOGETHER S OF
POINT CONCEPTION...BUT WIND PROFILES ARE NOT FAVORABLE MUCH PRECIP
ACCUMULATIONS. WENT AHEAD AND ADDED 20 PERCENT FOR TUE. TEMPS
WILL REMAIN COOLER THAN NORMAL THROUGH THIS PERIOD. HOWEVER...THERE
WILL BE A SLIGHT WARM UP ON WED AND THU. TEMPS WILL BE MORE IN LINE
WITH NORMAL FOR THIS TIME OF YEAR THU. ECMWF IS IN AGREEMENT WITH
TROUGH SETTING UP ON TUE AND QUICKLY MOVING THROUGH THE AREA.

KLAX...WILL CONTINUE TO HAVE W TO NW WINDS INCREASING TO 15 TO 25 KT
THIS AFTERNOON. THERE WILL BE SHOWERS IN THE AREA THIS MORNING AND
THERE IS A SLIGHT CHANCE OF ONE MOVING OVER THE AIRPORT. THESE

BRIEFLY TO NEAR 015. GOOD CONFIDENCE IN VFR TAF WITH MODERATE WEST
WINDS THIS AFTERNOON.

KBUR...SHOWERS WILL BE LESS LIKELY THAN AT KLAX. GOOD CONFIDENCE IN
VFR TAF. MODERATE WEST TO NORTHWEST WINDS IN THE MOUNTAINS COULD
CAUSE TURBULENCE ISSUES ON CLIMB AND DESCENT.

MORNING MUCH LESS SO IN THE VLYS AND DESERTS. NOT TOO MANY CLOUDS
THIS MORNING AND DESPITE THE SHOWERS FLYING CONDS SHOULD BE GOOD.
