SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
350 PM PST TUE DEC 30 2014

...UPDATED AVIATION DISCUSSION...

.SYNOPSIS...

A COLD LOW WILL BRING POSSIBLE PRECIPITATION AND BLUSTERY WINDS INTO
EARLY WEDNESDAY WITH TEMPERATURES TO DIP FURTHER BELOW NORMAL. THE
SUNRISE TEMPERATURES OF NEW YEARS DAY WILL BE THE COLDEST OF THE
WEEK. A HIGH WILL ARRIVE BY FRIDAY AND DOMINATE THE WEATHER INTO THE
MIDDLE OF NEXT WEEK WITH ABOVE NORMAL TEMPERATURES STARTING SUNDAY.

&&

.SHORT TERM (TODAY-FRI)...COLD UPPER LOW DROPPING SOUTH THROUGH
NEVADA THIS AFTERNOON. FINALLY STARTING TO GET A LITTLE SHOWER
ACTIVITY DEVELOPING ACROSS THE EASTERN PORTION OF THE LA BASIN AND
EVEN OVER INTERIOR SLO COUNTY AS WE GET SOME BRIEF UPSLOPE FLOW
INTERACTING WITH THE LOW LVL MOIST LAYER BEFORE THE NORTHEAST FLOW
TAKES OVER LATER THIS EVENING AND DRIES THINGS OUT. THE TRACK OF THE
UPPER LOW IS A BIT FURTHER EAST THAN MODELS HAD SHOWN A COUPLE DAYS
AGO AND EXPLAINS THE DECREASE IN MOISTURE NEAR THE LOW ITSELF. STILL
SEEMS LIKE THERE IS ENOUGH LINGERING MOISTURE OUT IN THE ANTELOPE
VALLEY ALONG WITH THE NORTHEAST FLOW TO GET SOME ISOLATED LIGHT
SHOWERS, THOUGH GUIDANCE POPS ARE ALL UNDER 20. PROBABLY THE BEST
CHANCE OUT THERE WILL BE IN THE FAR SOUTHEASTERN FOOTHILLS NEAR THE
SBD COUNTY LINE WHERE SOME LIGHT ACCUMULATIONS COULD STILL OCCUR.
SAME WITH THE ADJACENT EASTERN SAN GABRIELS NEAR THE WRIGHTWOOD AREA
AND WILL BE LEAVING THE WINTER WEATHER ADVISORY IN TACT THERE.
ELSEWHERE JUST ISOLATED LIGHT SHOWERS WITH AMOUNTS UNDER A TENTH OF
AN INCH.

OTHERWISE, SCREAMING MESSAGE FOR US WITH THIS EVENT WILL BE THE WIND
TONIGHT AND WEDNESDAY FOLLOWED BY COLD OVERNIGHT LOWS. THE WIND
TONIGHT WILL KEEP TEMPS MODERATED IN MANY LOWER ELEVATION AREAS,
THOUGH AV WILL DROP TO AROUND 20, WITH MID 20S IN THE INTERIOR SLO
COUNTY. OJAI AND CENTRAL COAST ALSO EXPECTED TO SEE FREEZING TEMPS
SINCE THOSE ARE SOMEWHAT PROTECTED FROM NE WINDS.

WINDS MOSTLY EXPECTED TO BE IN THE ADVISORY RANGE ACROSS LA/VENTURA
COUNTIES, BUT COULD SEE SOME ISOLATED 60 MPH GUSTS IN OUR FAVORITE
WINDY SPOTS IN THE LA MTNS AND PLACES LIKE WILEY RIDGE AND LAGUNA
PEAK. WINDS EXPECTED TO DROP OFF IN THE AFTERNOON AS USUAL. NEW
YEARS EVE AND MORNING OFFSHORE GRADIENTS ARE EXPECTED TO BE LIGHTER
AND SHOULD ALLOW MANY AREAS TO DROP TO NEAR OR BELOW FREEZING,
INCLUDING AROUND THE ROSE PARADE AREA, AND FREEZE AND HARD FREEZES
WATCHES ARE IN EFFECT. HOWEVER, THERE MAY BE JUST ENOUGH OFFSHORE
BREEZE TO MODERATE SOME AREAS LIKE PORTIONS OF COASTAL VENTURA
COUNTY.

ANOTHER COLD NIGHT FRIDAY NIGHT AND EXPECT FREEZE AND HARD FREEZES
IN MANY OF THE SAME PLACES AS NEW YEARS DAY. OTHERWISE, DRY AND
CLEAR WITH DAYTIME HIGHS 5-10 DEGREES BELOW NORMAL.

.LONG TERM (SAT-TUE)...PRETTY QUIET PATTERN. STILL CHILLY NIGHTS
THROUGH THE WEEKEND BUT WARMING DAYTIME HIGHS TO NEAR OR EVEN
SLIGHTLY ABOVE NORMAL BY SUNDAY. BY MONDAY AND TUESDAY LOOKS FOR
HIGHS WELL INTO THE 70S MOST LOWER ELEVATIONS AREAS UNDER CLEAR
SKIES.

&&

.AVIATION...30/234Z.
COLD UPPER LOW BRINGING ISOLATED TO SCATTERED SHOWERS TO THE REGION
THROUGH THIS EVENING. MOSTLY VFR CIGS BUT POCKETS OF MVFR CIGS WITH
SHOWER ACTVITY. NORTHEAST WINDS ON THE INCREASE DURING NEXT FEW HOURS
WITH STRONGEST BURST OF WINDS GENERALLY BETWEEN 04Z/12Z. DURING THIS
TIME...THERE WILL BE STRENGTHENING UPPER LEVEL WIND SUPPORT THAT
WILL INCREASE REPORTS OF LLWS AND TURBULENCE...INCLUDING
KLAX...KLGB...AND KBUR. POSSIBLE LLWS AT KVNY AND KOXR AS WELL.
NORTHEAST WIND COMPONENT WILL CONTINUE THROUGH MUCH OF THE DAY
TOMORROW BUT WINDS SPEEDS ARE NOT EXPECTED TO BE AS STRONG.

KLAX...MVFR TO VFR CEILINGS WITH OCCASIONAL RAIN SHOWER ACTIVITY
WILL CONTINUE THROUGH THIS EVENING...WITH DRYING TREND OVERNIGHT
AS NORTHEAST FLOW INCREASES. MAIN CONCERN TONIGHT WILL BE INCREASING
NORTH TO NORTHEAST WINDS WITH STRONGEST BURST EXPECTED BETWEEN
06Z AND 12Z. DURING THIS TIME...THERE IS INCREASING CONFIDENCE
THAT GUSTS UP TO 25 KT WITH LLWS WILL OCCUR.

KBUR...MVFR TO VFR CEILINGS WITH OCCASIONAL RAIN SHOWER ACTIVITY
WILL CONTINUE THROUGH THIS EVENING...WITH DRYING TREND OVERNIGHT AS
NORTHEAST FLOW INCREASES. MAIN CONCERN TONIGHT WILL BE INCREASING
NORTHEAST WINDS WITH STRONGEST BURST EXPECTED BETWEEN 04Z AND 12Z.
DURING THIS TIME...THERE IS INCREASING CONFIDENCE THAT GUSTS UP TO
25 KT WITH LLWS WILL OCCUR. SLIGHT CHANCE OF GUSTS UP TO 35 KT
DUE TO FAVORABLE UPPER LEVEL WIND SUPPORT.

&&

.MARINE...30/200 PM.

HIGH CONFIDENCE WITH CURRENT SMALL CRAFT ADVISORIES FOR THE OUTER
WATERS THROUGH LATE TONIGHT.

INNER WATERS SO CAL BIGHT...SMALL CRAFT ADVISORY WILL BE IN EFFECT
FROM LATE THIS AFTERNOON THROUGH WEDNESDAY MORNING FOR THE INNER
