NEW AVIATION DISCUSSION

.SHORT TERM...

LIGHT SHOWERS WERE OCCURING ACROSS THE NORTHERN PORTION OF THE CWA
THIS MORNING. FROM CAMBRIA WITH NEARLY A QUARTER OF AN INCH...TO
SANTA MARIA WHERE SHOWERS JUST STARTED RECENTLY. THIS RELATIVELY
WEAK FRONT SHOULD HOLD TOGETHER AS IT MOVES S OF POINT CONCEPTION TO
BRING A TENTH OF AN INCH MAX TO MOST AREAS IN SOUTHERN SBA COUNTY AS
WELL AS VTU AND LA COUNTY LATER THIS AFTERNOON AND EARLY EVENING
HOURS. STRONG NORTHERLY WINDS WILL DEVELOP IN THE WAKE OF THIS QUICK
MOVING COLD FRONT. CURRENTLY HIGH WIND WATCH IS UP FOR THE LA/VTU
COUNTY MOUNTAINS INCLUDING THE SANTA MONICA MOUNTAIN RANGE. THIS
WILL LIKELY BE UPGRADED TO HIGH WIND WARNING WITH THE AFTERNOON ZONE
PACKAGE. TIMING SHOULD BE FROM THIS EVENING THROUGH MID MORNING FRI.
WIND ADVISORIES WILL LIKELY BE ADDED AS WELL FOR THE NORTHERLY WIND
PRONE AREAS SUCH AS SANTA CLARITA...WESTERN SAN FERNANDO
VALLEY...AND THE HOLLYWOOD HILLS TO THE PASSES AND CANYONS OF MALIBU
TO LEO CARILLO. FOR NOW...WILL LEAVE VENTURA COUNTY OUT OF THIS WIND
ADVISORY UNTIL WINDS BEGIN TO SHIFT OUT OF THE NE BY FRI NIGHT
THROUGH SAT WHEN MOST ALL LOCATIONS IN LA/VTU COUNTIES WILL LIKELY
NEED WIND ADVISORIES. SNOW LEVELS WILL DROP SIGNFICANTLY OVERNIGHT
WHICH SHOULD NOT BE A HUGE FACTOR...EXCEPT FOR THE NORTHERN SLOPES
OF SBA/VTU AND WESTERN LA COUNTY MOUNTAINS. BESIDES STRONG AND
DANGEROUS GUSTY WINDS...SOME LOCALIZED SNOWFALL COULD BE PART OF THE
MIX OVERNIGHT THROUGH EARLY FRI MORNING THROUGH THE INTERSTATE 5
CORRIDOR. SNOW LEVELS SHOULD LOWER TO 3500 TO 4000 FT LATE TONIGHT.
NOT EXPECTING MUCH IN SNOWFALL ACCUMULATIONS THROUGH THE I-5
CORRIDOR. 1-2 INCHES POSSIBLE FROM MIDNIGHT THROUGH FRI MORING
HOURS.

...FROM PREVIOUS DISCUSSION...

THE RAIN IS NOT THE ISSUE WITH THIS FRONT IT IS WINDS BEHIND IT. AT
FIRST SOUTHWEST GRADIENTS WILL TIGHTEN AHEAD OF THE FRONT AND WILL
CREATE FREQUENT GUSTS TO 45 MPH IN THE ANTELOPE VALLEY THESE WINDS
WILL LAST TO THE EARLY EVENING. OVERNIGHT COL AIR WILL SPILL INTO
THE AREA AS THKNS DUMPS 10 DM IN 12 HOURS BY 12Z FRIDAY THE GRADIENT
TO BFL WILL BE -5 MB 925 MB WINDS ARE IN THE 45-50 KT RANGE. HIGH
WIND WATCHES ARE IN EFFECT FOR THE MOUNTAINS OF VTA AND L.A.
COUNTIES AS WELL AS THE SANTA MONICAS. WIND ADVISORIES WILL LIKELY
BE NEEDED ALONG THE SANTA BARBARA SOUTH COAST AND THE SANTA YNEZ
RANGE...THE SANTA CLARITA VALLEY...AND THE EASTERN PORTIONS OF THE
VENTURA COUNTY VALLEYS. HIGH WIND WARNINGS ARE ON THE BUBBLE AND
WILL LET DAY SHIFT ANALYZE THE FRONT AND THE 12Z TO MAKE THE
DECISION ON A STRONG WAD OR A WIND WARNING.

WITH ALL THE COLD AIR TEMPS ON FRIDAY WILL BE WELL BELOW NORMAL
DESPITE MORE SUNSHINE THEN WE HAVE SEEN IN A FEW DAYS.

THE UPPER LEVEL WINDS SWITCH TO THE NE SATURDAY MORNING ALL THE
THERMAL ADVECTION IS GONE AND WHILE THERE WILL BE SOME GUSTY WINDS
IT IS LIKELY THAT ADVISORIES WILL NOT BE NEEDED. STILL COOL AS ALL
THE COLD AIR WILL NOT HAVE MODIFIED MUCH.

.LONG TERM...
EC AND GFS IN A VAGUE SENSE OF AGREEMENT FOR SOCAL SUNDAY AND MONDAY
ENOUGH TO SAY THE WEATHER WILL BE FAIR WITH TEMPS AROUND NORMAL.

AFTER MONDAY ALL MODELS GO OFF IN VERY DIFFERENT DIRECTIONS.
UNCHARACTERISTICALLY THE EC IS BRING NEW SOLNS WITH EVERY RUN THE
GFS HAS BEEN MORE CONSISTENT ALTHOUGH BOTH THE INSIDE SLIDER ON
CHRISTMAS AND RIDGE ON WEDNESDAY ARE A LITTLE SHARPER. FAVOR THE GFS
SOLN BECAUSE OF RUN TO RUN CONSISTENCY. COOLED DAYS 6 AND 7 A LITTLE
MORE AS HGTS ARE LOWER.

.AVIATION...20/2030Z

MOSTLY CLOUDY SKIES WILL GRADUALLY CLEAR FROM THE NORTHWEST DURING
THE DAY. THERE WILL BE A CHANCE OF LIGHT RAIN SHOWERS INTO THE LATE
