SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
1000 PM PST MON DEC 28 2015

NEW AVIATION DISCUSSION

.SYNOPSIS...

THE SHOWERS WILL MOVE EAST TONIGHT AS AN AREA OF LOW PRESSURE EXITS
THE REGION. FAIR SKIES WILL CONTINUE THE REST OF THE WEEK AS HIGH
PRESSURE BUILDS IN ALOFT WITH BREEZY WINDS AT TIMES. TEMPERATURES
SHOULD WARM TO NORMAL BY NEW YEARS DAY. A STORM SYSTEM COULD BRING A
COOL AND WET WEATHER PATTERN TO THE REGION EARLY NEXT WEEK.

&&

.UPDATE...

LATEST SATELLITE IMAGERY INDICATES A TROUGH OF LOW PRESSURE CENTERED
OVER THE MOJAVE DESERT. A FEW SHOWERS ARE LINGERING OVER THE AREA
THIS EVENING...ESPECIALLY ALONG THE NORTHERN SLOPES OF THE
MOUNTAINS. SPOTTER REPORTS NEAR THE INTERSTATE 5 CORRIDOR IN THE
GRAPEVINE AREA SUGGEST LIGHT SNOW IS FALLING IN THE FRAZIER PARK
AREA AND IN SURFACE OBSERVATIONS AT SANDBERG. WITH TEMPERATURES
ALREADY IN THE LOWER TO MID 30S AND ECHOES ON KEYX RADAR...A FEW
SNOW SHOWERS OR FLURRIES CANNOT BE RULED OUT IN THE ANTELOPE VALLEY.
HOWEVER..NO SNOW ACCUMULATION IS EXPECTED AT THIS TIME.
909 CURRENT WIND HEADLINES LOOK AGREEABLE AND A MINOR TWEAK WILL
LIKELY BE MADE TO ADD THE SANTA CLARITA VALLEY TO THE WIND
ADVISORIES.
WINDS WILL CONTINUE TO INCREASE TONIGHT ACROSS THE REGION AS THE
COLDEST AIR PUNCHES IN AND A STRONG TEMPERATURE AND PRESSURE
GRADIENT DEVELOPS AFTER MIDNIGHT ACROSS THE SOUTHERN CALIFORNIA
MOUNTAINS.

A COLD AIR MASS WILL SETTLE INTO THE REGION THROUGH WEDNESDAY.
CURRENT FROST AND FREEZE PRODUCTS LOOKS GOOD AND NO ADJUSTMENTS ARE
PLANNED AT THIS TIME.

AN UPDATE WILL BE ISSUED TO THE PACKAGE SHORTLY.

&&

.PREV DISCUSSION...

SHORT TERM...COOL WEATHER THROUGH THU BUT WARMING A COUPLE DEGREES
EACH DAY STARTING WEDNESDAY. LIGHT OFFSHORE FLOW WILL TURN INTO A
MODERATE SANTA ANA BY THURSDAY MORNING WITH ADVISORY LEVEL NORTHEAST
WINDS LIKELY IN THE USUAL PARTS OF LA/VENTURA COUNTIES. OVERNIGHT
TEMPS WILL REMAIN COLD IN WIND PROTECTED LOCATIONS AND ADDITIONAL
FROST/FREEZE HEADLINES MAY BE NEEDED.

LONG TERM...MODERATE SANTA ANA TO CONTINUE FRIDAY THEN WEAKENING
SATURDAY AS GRADIENTS AND UPPER SUPPORT WEAKEN. DAYTIME TEMPS SHOULD
CONTINUE TO SLOWLY CLIMB BUT STILL CHILLY OVERNIGHT.
FOR SUNDAY AND MONDAY MODELS CONTINUE TO INDICATE A PATTERN CHANGE
AS ENERGY STARTS TO UNDERCUT THE WEST COAST REX BLOCK AND OPENING
THE DOOR FOR WETTER STORMS TO MOVE INTO SOUTHERN CALIFORNIA.
HOWEVER, THERE CONTINUES TO BE SIGNIFICANT RUN TO RUN AND MODEL TO
MODEL DIFFERENCES IN TIMING AND STRENGTH. THE GFS REMAINS WET BUT
NOT AS WET AS EARLIER RUNS WITH A MORE PROGRESSIVE PATTERN AND
FASTER MOVING SYSTEMS. THE ECMWF HAS SHIFTED A LOT OF THE ENERGY AND
MOISTURE SOUTH OF THE BORDER AND REALLY DOESN'T BRING ANYTHING TO
OUR AREA UNTIL TUESDAY, AND FAIRLY LIGHT PRECIP AT THAT. THE GEM IS
SIMILAR IN TIMING AND STRENGTH AS THE EC. STILL REALLY EARLY IN THE
GAME AND IT WILL LIKELY BE ANOTHER FEW DAYS AT LEAST BEFORE MODELS
SETTLE ON A PREFERRED SOLUTION. AT THIS POINT THOUGH, LOOKING AT THE
ENSEMBLES, STANDARDIZED ANOMALIES, AND ATMOSPHERIC RIVER TOOLS FOR
EARLY NEXT WEEK NOTHING IS REALLY INDICATING ANYTHING MORE THAN AN
AVERAGE WINTER STORM STORM AT BEST.
