SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
350 AM PST THU FEB 7 2013

.SYNOPSIS...

PARTLY CLOUDY WITH SOME COASTAL MORNING LOW CLOUDS TODAY. LATER
TONIGHT AN ALASKAN LOW WILL BRING SHOWERS AND WINDS WITH LOW
ELEVATIONS SNOW AND A SLIGHT CHANCE OF A THUNDERSTORM TO THE AREA
THROUGH EARLY SATURDAY. THE AFTERNOON TEMPERATURES WILL BE BELOW
NORMAL INTO SUNDAY...WITH FRIDAY AND SATURDAY THE COLDEST. THE LOW
SHOULD MOVE EAST ON SATURDAY FOR DECREASING CLOUDS AN A WARMING
TREND TO START ON SUNDAY...WITH TEMPERATURES BACK TO THE SEASONAL
NORMALS BY MIDWEEK.

&&

.SHORT TERM (TODAY-SAT)...
ALL EYES ON FRIDAY WITH NOT MUCH HAPPENING TODAY. SOME LOW CLOUDS
HAVE FORMED WITH A WEAK EDDY SOUTH OF POINT CONCEPTION AND THROUGH
RADIATIONAL COOLING ACROSS THE CENTRAL COAST AND SNS RVR VLY. HGTS
WILL FALL THROUGH THE DAY AND MAX TEMPS WILL BE 4 TO 8 DEGREES BLO
NORMAL.

A VERY COLD UPR LOW WILL MOVE DOWN THE CA/NV BORDER LATER TONIGHT
BEFORE KICKING EAST LATER FRIDAY AFTERNOON. THIS SYSTEM IS PRETTY
MOISTURE STARVED AND HAS LITTLE OR NO SOUTH SFC FLOW ASSOC WITH IT.
IT IS VERY COLD AND THIS WILL HELP WRING WHAT EVER MOISTURE IT
BRINGS OUT OVER THE AREA. THE RAIN WITH THIS SYSTEM WILL ALL BE
EMBEDDED IN NW FLOW. NW FLOW SYSTEMS BRING THE BEST CHC OF PRECIP TO
THE MTNS (ESP THE NORTHERN PORTIONS)...THE EASTERN PORTIONS OF L.A.
COUNTY AND ORANGE COUNTY. THE SBA SOUTH COAST AND THE VTA COAST
USUALLY SEE VERY LITTLE IN THE WAY OF PRECIP FROM THESE SYSTEMS. THE
VERY COLD AIR WILL DESTABILIZE THE ATMOSPHERE ENOUGH TO WARRANT A
SLIGHT CHC OF TSTMS BUT ONLY A SLGT CHC AS THE LOWER ATMOSPHERE WILL
BE QUITE COLD AS WELL AND THERE IS NOT TOO MUCH PVA EITHER.

SNOW WILL ACTUALLY BE THE BIGGEST ISSUE WITH THIS SYSTEM. SNOW
LEVELS WILL START OUT AROUND 6000 FEET LATE TONIGHT BUT WILL LOWER
TO 4000 FEET BY FRIDAY MORNING AND THEN DOWN TO 2500 TO 3000 FEET BY
FRIDAY EVENING. SNOW WILL AFFECT ALL MTN ROADS AND EVEN THE ANTELOPE
AND CUYAMA VLYS. THE BEST SNOWFALL WILL OCCUR ABOVE 4000 FEET ON THE
NORTHERN SECTIONS OF THE MTNS WHERE 4 TO 8 INCHES OF SNOW WILL
LIKELY FALL. THERE WILL BE 2 TO 4 INCHES AT LOWER ELEVATIONS AND
ACROSS THE MORE SOUTHERN SECTIONS OF THE MTNS. A WINTER WEATHER
ADVISORY IS IN EFFECT FROM MIDNIGHT TONIGHT TO NOON AND SATURDAY.

IT WILL ALSO BE WINDY. THE MTNS AND THE AV WILL SEE WINDS INCREASING
AFTER MIDNIGHT TONIGHT AS THE GRADIENTS TIGHTEN WITH THE APPROACHING
LOW. GUSTS TO 45 MPH WILL DEVELOP. AFTER THE COLD AIR START TO POUR
IN FRIDAY WEST WINDS WILL INCREASE ACROSS THE COASTAL AREAS AND WIND
ADVISORIES MAY BE NEEDED FRIDAY AFTERNOON AND EVENING FOR WEST WINDS
GUSTS TO 35 MPH.

RAINFALL WITH THIS SYSTEM WILL BE QUITE VARIABLE BUT MOST COAST AND
VLY AREAS WILL SEE MUCH LESS AND WOULD NOT BE SURPRISED IF SOME
AREAS RECEIVED NOTHING. IN CASE PEOPLE WERE WONDERING THE MDLS HAVE
NOT CHANGED THEIR RESPECTIVE TUNES WITH THE EC THE WETTEST AND THE
NAM THE WAY DRIEST.

MAX TEMPS WILL TUMBLE WITH THE HGTS FALLING TO 542 DM. AMONGST THE
FALLING HGTS THE CLOUDS AND RAIN MAX TEMPS WILL FALL TO 12 TO 20
DEGREES BELOW NORMAL.

THE STORM PULLS OUT SATURDAY AND SKIES WILL CLEAR. SOME NORTH SLOPES
SNOW SHOWERS MAY LINGER IN THE MORNING BUT OTHERWISE IT WILL BE
DRY. MAX TEMPS WILL WARM BUT WILL REMAIN 10 TO 15 DEGREES BLO
NORMALS.

.LONG TERM (SUN-WED)...

PRETTY DULL WEATHER THEN SETS UP OVER THE AREA FOR THE XTND PERIOD.
THE EAST PAC HIGH IS NOT AS SHARP AND DOES NOT BEND INTO WASHINGTON
AND THE RESULTING UPPER FLOW PATTERN IS MORE NORTHERLY RATHER THAN
NORTHEASTERLY THIS WILL ALLOW FOR A FEW MORE DEGREES OF WARMING THAT
PREVIOUSLY THOUGHT. IT WILL BE COOL ENOUGH TO PREVENT ANY MARINE
LAYER FROM FORMING. MAX TEMPS WILL SLOWLY RISE THROUGH THE PERIOD
BUT WILL REMAIN BLO NORMAL THROUGH THE PERIOD BUT ONLY BY A DEGREE
OR TWO ON WEDNESDAY. OVERNIGHT LOWS WILL BE QUITE COOL SUN AND MON
AND A FEW FROST ADVISORIES MAY BE NEEDED.
