SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
957 AM PST FRI FEB 6 2015

.SYNOPSIS...
A FRONTAL SYSTEM APPROACHING FROM THE WEST WILL BRING AN INCREASE IN
CLOUDS AND A CHANCE OF RAIN FOR NORTHERN SECTIONS BY LATE AFTERNOON.
RAIN IS EXPECTED ACROSS MUCH OF THE REGION TONIGHT THROUGH
SATURDAY...HEAVIEST FROM SANTA BARBARA COUNTY NORTHWARD. ANOTHER LOW
PRESSURE SYSTEM WILL BRING A GOOD CHANCE OF RAIN FOR NORTHERN AREAS
SUNDAY THROUGH MONDAY MORNING. SANTA ANA CONDITIONS MAY DEVELOP NEXT
WEEK.

&&

.SHORT TERM (TODAY-SUN)...
A FEW FORECAST TWEAKS FOR THIS MORNING. THE MID-TO-UPPER LEVEL
CLOUDS THAT WERE AROUND EARLIER THIS MORNING HAVE PUSHED THROUGH
QUICKLY LEAVING SUNNY SKIES OVER THE MAJORITY OF THE AREA. THE ONLY
AREAS THAT SHOULD SEE SIGNIFICANT CLOUDS TODAY WILL BE SLO
COUNTY...AND POSSIBLY THE INTERIOR SECTIONS WITH POSSIBLE WAVE-LIKE
CLOUDS. TEMPERATURES WILL BE COOLER FROM YESTERDAY AS THE RAIN
SYSTEM APPROACHES AND ONSHORE PRESSURE GRADIENTS DEVELOP...BUT WILL
REMAIN ABOVE NORMAL WITH THE AMPLE SUNSHINE. THE DETAILS FOR THE
STORM LOOK GOOD FROM THE PREVIOUS SHIFT...INCLUDING RAIN AMOUNTS.
ONLY TWEAK WAS TO INCREASE THE POPS TO HIGH CHANCE FOR THE NORTHWEST
TIP OF SLO COUNTY THIS AFTERNOON...AS THE FRONT EDGE OF THE RAIN
BAND SHOULD CROSS INTO THE COUNTY SOMETIME BETWEEN 4 AND 8 PM. AS
FAR AS THUNDERSTORM POTENTIAL IS CONCERNED...ALL THE CONVECTIVE
INDICATORS IN THE MODELS ARE MINIMAL EXCEPT FOR DECENT K-INDEX
VALUES. CURIOUSLY ENOUGH...THE BAND IS CURRENTLY PRODUCING QUITE A
BIT OF LIGHTNING AROUND SAN FRANCISCO AND EASTWARD RIGHT NOW. WILL
HAVE TO TAKE A CLOSER LOOK TODAY AT WHETHER OR NOT TO ADD A SLIGHT
CHANCE FOR SLO COUNTY THIS EVENING.

***FROM PREVIOUS DISCUSSION***

A SWATH OF DEEP SUBTROPICAL MOISTURE...WITH PRECIPITABLE WATER
VALUES BETWEEN 1.5 AND 1.7...AIMED AT NRN AND CENTRAL CA TODAY WILL
SLOWLY SAG SOUTHWARD TONIGHT. RAIN WILL DEVELOP ACROSS SLO COUNTY
THIS EVENING...THEN ACROSS ALL OF SBA COUNTY BY MIDNIGHT...PROBABLY
PUSHING INTO VTU COUNTY BY DAYBREAK. THE SOUTHWARD PROGRESSION OF
THIS AXIS OF RAIN WILL THEN TEND TO SLOW...SO CONFIDENCE IN RAIN
REACHING LOS ANGELES COUNTY IS LOWER. STILL...RAIN IS LIKELY ACROSS
WRN AND NRN L.A. COUNTY SATURDAY...WITH JUST A CHANCE OF RAIN ACROSS
SRN SECTIONS. MEANWHILE...PERIODS OF RAIN WILL CONTINUE ACROSS SLO
AND SBA COUNTIES. MAX TEMPS WILL BE DOWN A FEW MORE DEGREES IN MOST
AREAS ON SATURDAY...TO GENERALLY SLIGHTLY BELOW NORMAL LEVELS.

IT APPEARS AS THOUGH THE RAIN MAY LIGHTEN UP IN MOST AREAS SAT
NIGHT...AND COULD END FOR A WHILE. THEN...AN UPPER LOW AND
ASSOCIATED SURFACE LOW WILL MOVE TO A POSITION NEAR 38N/132W BY
EARLY SUNDAY MORNING. THIS WILL LIKELY CAUSE RAIN TO BECOME STEADY
ONCE AGAIN...ESPECIALLY ACROSS SLO AND NRN SBA COUNTIES ON SUNDAY.
THE SRN END OF THAT AREA OF RAIN MAY AFFECT VTU COUNTY LATE SUNDAY
INTO EARLY MONDAY. AT THIS TIME...IT APPEARS THAT LOS ANGELES COUNTY
WILL ONLY HAVE A SLIGHT CHANCE OF RAIN OR SHOWERS WITH THAT SYSTEM
LATE SUNDAY NIGHT OR EARLY MON.

THERE WILL BE GUSTY SOUTHERLY WINDS AT TIMES TONIGHT THROUGH
SUNDAY...ESPECIALLY IN THE MOUNTAINS AND ACROSS THE CENTRAL COAST.
WINDS COULD GET CLOSE TO ADVISORY LEVELS IN SOME AREAS...ESPECIALLY
TONIGHT INTO SAT MORNING.

RAINFALL TOTALS FROM TONIGHT THROUGH EARLY MONDAY COULD BE FAIRLY
HEFTY...ESPECIALLY ACROSS SLO AND NRN SBA COUNTIES...AND ESPECIALLY
IN THE HIGHER TERRAIN OF NWRN SLO COUNTY. EXPECT GENERAL 1.5 TO 3
INCH RAINFALL TOTALS ACROSS SLO COUNTY...WITH LOCAL TOTALS OF 4 TO 6
INCHES POSSIBLE ACROSS THE HIGHER TERRAIN OF NWRN SLO COUNTY.
RAINFALL AMOUNTS ACROSS SBA COUNTY SHOULD AVERAGE 0.75 TO 1.5
INCHES...WITH LOCAL TOTALS OF 2 TO 3 INCHES IN HIGHER ELEVATIONS.
RAINFALL TOTALS WILL DROP OFF QUICKLY SOUTH OF SBA COUNTY...WITH ONE
QUARTER TO ONE INCH EXPECTED ACROSS VTU COUNTY...AND THE HIGHER
TOTALS CONFINED TO THE WESTERN MOUNTAINS. AT THIS POINT...EXPECT
RAINFALL TOTALS ACROSS MOST OF LOS ANGELES COUNTY TO BE ONE QUARTER
OF AN INCH OR LESS.

DUE TO THE SUBTROPICAL NATURE OF THIS SYSTEM...SNOWFALL TOTALS WILL
BE VERY HIGH THROUGH MONDAY...MAINLY ABOVE 8000 FEET...SO DO NOT
EXPECT SNOW ACCUMULATIONS TO POSE MUCH OF A THREAT.

.LONG TERM (MON-THU)...A BROAD TROUGH WILL LINGER ACROSS THE AREA
MONDAY INTO EARLY TUE...BUT ANY PRECIPITATION WILL LIKELY END IN
MOST AREAS MON MORNING. AN UPPER LOW WILL DROP SWD INTO THE GREAT
BASIN ON TUE. THIS MAY CAUSE SOME GUSTY NW WINDS TO DEVELOP ACROSS
PORTIONS OF THE FCST AREA. MAX TEMPS WILL BE NEAR NORMAL MON AND
TUE. SOME MODELS SHOW THE UPPER LOW DROPPING SOUTHWESTWARD TO THE
SOUTH OF THE FCST AREA WED AND THU...WITH LOW LEVEL OFFSHORE FLOW
DEVELOPING. THIS COULD BRING A ROUND OF GUSTY SANTA ANA WINDS TO THE
FCST AREA WED INTO THU.

&&

.AVIATION...06/1800Z...
