SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
330 AM PST FRI JAN 8 2016

.SYNOPSIS...

DRY AND COOL WEATHER WILL PREVAIL ACROSS THE AREA THROUGH TONIGHT. A
WEAK COLD FRONT WILL BRING SHOWERS TO THE AREA SATURDAY AND SATURDAY
NIGHT. DRY WEATHER WILL RETURN FOR SUNDAY INTO MONDAY FOR MOST
AREAS...THEN A COUPLE OF WEAK WEATHER SYSTEMS WILL BRING A SLIGHT
CHANCE OF RAIN TO SOUTHWESTERN CALIFORNIA THROUGH THE MIDDLE OF NEXT
WEEK. TEMPERATURES WILL REMAIN COOLER THAN NORMAL THROUGH THE PERIOD.

&&

.SHORT TERM (TODAY-SUN)... AN UPPER RIDGE AND WEAK NORTH OFFSHORE
FLOW WILL COMBINE TO PRODUCE A MOSTLY SUNNY DAY. THERE IS JUST
ENOUGH OF AN OFFSHORE PUSH FOR AN I-5 CORRIDOR WIND ADVISORY THROUGH
MID MORNING. THE COOL DRY AIR MASS AND CLEAR SKIES COMBINED TO
PRODUCE CHILLY EARLY MORNING LOW TEMPERATURES AND THERE WILL LIKELY
BE SOME TEMPS NEAR 32 DEGREES IN THE OJAI VLY.

TONIGHT SHOULD BE PRETTY UNEVENTFUL AS THE RIDGE BEGINS BREAK DOWN.
THERE WILL BE AN INCREASE IN CLOUDS ACROSS SLO COUNTY AS WEAK
IMPULSE BEGINS TO APPROACH THE COAST.

MDLS HAVE BEEN FLIP FLOPPING ON THE SYSTEM SLATED TO MOVE THROUGH
THE AREA SATURDAY. TODAYS RUNS FAVOR A WEAKER SLOWER SYSTEM AND IT
LOOKS LIKE A HIGH POP LOW QPF TYPE OF EVENT. ALL MDLS ARE A LITTLE
SLOWER SO KEPT LOW POPS AROUND INTO SATURDAY NIGHT. THIS LOOKS LIKE
A TENTH OF AN INCH TO A QUARTER INCH TYPE OF SYSTEM WITH RAINFALL
RATES UNDER A QUARTER INCH PER HOUR. THE AIRMASS IS PRETTY STABLE SO
THERE IS NO THREAT OF TSTMS, SNOW LEVELS WILL BE NEAR 5500 FEET AND
AREAS ABOVE 6000 FEET WILL SEE A FEW INCHES OF NEW SNOW.

A LITTLE RIDGE POPS IN ON SUNDAY BUT BEFORE IT CAN ESTABLISH ITSELF
THE OUTGOING SYSTEM WILL LINGER JUST LONG ENOUGH TO WARRANT A SLIGHT
CHC OF RAIN OVER L.A. COUNTY IN THE MORNING. OTHERWISE SKIES WILL
CLEAR. MAX TEMPS WILL WARM A DEGREE OR TWO BUT WILL 6 OR SO DEGREES
BLO NORMAL.

.LONG TERM (MON-THU)... A WEAK TROF TRIES TO FIGHT ITS WAY THROUGH
THE RIDGE ON MONDAY AND FOR THE MOST PART FAILS. THE BEST IT CAN
MANAGE IS CHC OF RAIN FOR THE CENTRAL COAST. RAINFALL IF ANY WILL BE
A TENTH OR LESS. OTHERWISE SKIES WILL BE CLOUDIER AND MAX TEMPS WILL
REMAIN BLO NORMAL.

ANOTHER RIDGE ON TUESDAY WILL MAKE FOR PLEASANT MOSTLY SUNNY DAY.

ANOTHER TROF TRIES TO MAKE ITS WAY PAST THE RIDGE ON WEDNESDAY. AT
ONE TIME THE MDLS WERE KEEN ON MAKING THIS SYSTEM A FAIRLY LARGE ONE
WITH DECENT AMOUNTS OF RAINFALL. NOW...NOT SO MUCH. KEPT POPS IN
OVER THE ENTIRE AREA ALTHO CURRENT MDL THINKING KEEP THINGS CONFINED
TO THE CENTRAL COAST...BUT YOU NEVER KNOW WHAT TODAYS MDL RUNS WILL
BRING THERE WILL BE SOME CLOUDS AND MAX TEMPS REALLY SHOULD NOT
CHANGE MUCH.

MDLS HINT AT A DRY INSIDE SLIDER FOR THURSDAY WHICH WOULD LEAD TO
BREEZY DRY AND COOL CONDITIONS.

SPEAKING OF COOL DOWNTOWN L.A. HAS NOT HAD A MAX TEMP ABOVE NORMAL
SINCE THE 18TH OF DEC (IT REACHED NORMAL ONCE ON THE 23RD) AND THE
CURRENT FORECAST INDICATES THAT THE NEXT 10 WILL BE BLO NORMAL ALSO.
