SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
350 AM PST MON NOV 16 2015

...MARINE AND AVIATION DISCUSSIONS UPDATED...

.SYNOPSIS...

A COLD TROUGH OF LOW PRESSURE OVER THE REGION WILL BRING A COOL
AND BREEZY WEATHER PATTERN TODAY THROUGH TUESDAY. WARMER AND DRY
WEATHER IS EXPECTED WEDNESDAY THROUGH FRIDAY.

&&

.SHORT TERM (TODAY-WED)...
CURRENTLY A COOL 542 DM UPPER LOW SITS ATOP OF NV. STRONG NW TO SE
FLOW ON THE WEST SIDE OF THIS LOW IS OVER SRN CA. A THE SFC A STRONG
NW TO SE GRADIENT HAS SET UP OVER THE STATE. THIS NORTH FLOW IS
PILING CLOUDS UP AGAINST THE NORTH SLOPES WHERE THE OROGRAPHIC LIFT
IS SQUEEZING OUT SOME SNOW SHOWERS. 3 TO 7 INCHES OF SNOW ARE
POSSIBLE ABOVE 4500 FEET AND ACCUMULATING SNOW IS LIKELY DOWN TO
3000 FEET. THE COMBINATION OF SNOW...WIND AND LOW VISIBILITY HAZARDS
ARE ALL ENCOMPASSED BY A WINTER WEATHER ADVISORY WHICH IS IN EFFECT
UNTIL 100O AM THIS MORNING.

WINDS ARE THE OTHER ISSUE TODAY. THERE WAS A SLIGHT DELAY OF THE
STRONGEST WINDS BUT CURRENT OBS SHOW WIND SPEEDS JUST NOW PICKING UP
AND THIS TREND SHOULD CONTINUE TO MID MORNING WHEN THE LATEST
COMPUTER WIND MDLS PREDICT THE WINDS TO BE AT MAXIMUM STRENGTH.

OTHERWISE 537 DM THICKNESS WILL MAKE FOR A CHILLY DAY WITH MAX TEMPS
AROUND 10 DEGREES BLO NORMAL DESPITE PLENTY OF SUNSHINE.

CLEAR AND BREEZY TONIGHT AS THE WINDS TAKE ON MORE OF A NORTHEAST
CHARACTERISTIC IN RESPONSE TO SFC HIGH PRESSURE SETTING UP IN
NEVADA. RIGHT NOW IT LOOKS LIKE THE CURRENT WIND WARNING IS A LITTLE
OPTIMISTIC AND WOULD NOT BE SURPRISED IF AFTER VIEWING THE 12Z MDL
RUNS AND LATE MORNING OBSERVATIONS THE MTN WIND WARNINGS ARE DOWN
GRADED TO STRONG ADVISORIES. PLENTY COLD TONIGHT WITH ALL THE
MTNS...DESERTS AND INTERIOR VLYS SLATED FOR FREEZING TEMPERATURES.
WHILE THE NORMAL WARM COASTS WILL NOT BE FREEZING IT WILL STILL FEEL
RATHER COOL WITH LOWS NEAR 40 (OR NEAR 45 IN THE URBAN HEAT ISLANDS)

LOOK FOR A PRETTY DECENT SANTA ANA WIND EVENT TUESDAY MORNING. IT
LOOKS LIKE THERE MAY BE A NEED FOR SEVERAL WIND ADVISORIES. HGTS
CLIMB TO 581 DM AS A LARGE EAST PAC RIDGE NOSES INTO THE STATE.
THESE HGTS ALONG WITH MAXIMUM SUN AND OFFSHORE FLOW WILL CAUSE TEMPS
TO JUMP ESP IN THE VLYS WHERE 10 DEGREE CHANGES FROM TODAY WILL BE
COMMON.

A LITTLE LESS WIND WEDNESDAY AS THE SFC SHRINKS A LITTLE. ITS LIKELY
THERE WILL BE NO NEED FOR ANY MORE WIND ADVISORIES. HGTS CONTINUE TO
CLIMB AND MAX TEMPS WILL BE ABOVE NORMAL FOR MOST OF THE COASTS AND
VLYS.

.LONG TERM (THU-SUN)...
ALL MDLS AGREE THAT THE EAST PAC RIDGE AND WEAK OFFSHORE FLOW WILL
REMAIN IN PLACE THROUGH FRIDAY. LOOK FOR ABOVE NORMAL HIGHS AND
BELOW NORMAL LOWS (AT LEAST AWAY FROM THE WINDY CANYONS) EACH DAY
AND NIGHT. THURSDAY WILL LIKELY BE THE WARMEST DAY OF THE NEXT 7.
THERE WILL A A DEGREE OR TWO OF COOLING ON FRIDAY AS THE OFFSHORE
FLOW RELAXES AND THE RIDGE STARTS TO FLATTEN OUT.

A RETROGRADING TROF MOVES INTO THE AREA ON SATURDAY. IT WILL
INCREASE THE ONSHORE FLOW AND LOWER THE HGTS. THE SKIES MAY TURN
PARTLY CLOUDY ALTHOUGH THIS TROF LOOKS SUPER DRY. THE MAIN EFFECT
WILL BE A GOOD SIZED COOL DOWN.

IT WILL BE A LITTLE COOLER ON SUNDAY (GFS FCSTS A LITTLE MORE
TROFFING AND SLIGHTLY LOWER HGTS) OR QUITE A BIT COOLER (EC WITH A
SHARP TROF AND MUCH LOWER HGTS) FOR NOW SPLIT THE DIFFERENCE BETWEEN
THE TWO.
