SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
340 AM PDT WED APR 4 2012

.SYNOPSIS...

A WEAK COLD FRONT WILL APPROACH THE CENTRAL COAST TODAY. THIS FRONT
WILL BRING PARTLY CLOUDY SKIES TO THE AREA ALONG WITH COOLER
TEMPERATURES AND GUSTY WINDS. IT WILL BE BREEZY AND COOL THROUGH
FRIDAY. IT WILL BE SUNNY AND WARM OVER THE WEEKEND WITH A SLIGHT
COOLING TREND SLATED FOR NEXT WEEK.

&&

.SHORT TERM (TODAY-FRI)...
WEAK AND DRY COLD FRONT MOVING OVER THE CENTRAL COAST AT THE MOMENT.
THIS FRONT HAS CREATED A PATCHY MARINE LAYER OVER THE CENTRAL COAST
AND PARTLY CLOUDY SKIES ELSEWHERE. A -4.5MB MB GRADIENT FROM SMX TO
SBA IS PRODUCING WIND GUSTS TO 45 MPH THROUGH AND BELOW A FEW OF THE
PASSES AND CANYONS OF THE SANTA YNEZ RANGE. WIND ADVISORIES ARE IN
EFFECT FOR THE SANTA BARBARA MTNS AND THE SOUTH COAST. A WIND
ADVISORY IS ALSO IN EFFECT FOR THE I-5 CORRIDOR. THIS ADVISORY IS
NOT DOING TOO WELL AT THE MOMENT BUT THE GRADIENTS SHOULD TIGHTEN UP
AROUND DAWN AND THERE WILL BE A BRIEF FLARE UP. WINDS WILL REALLY
INCREASE ACROSS THE CENTRAL COAST THIS AFTERNOON BEHIND THE FRONT
AND A WIND ADVISORY WAS ADDED THERE. THESE WINDS WILL WORK THEIR WAY
THROUGH THE SANTA YNEZ RANGE AND INTO THE SBA SOUTH COAST SO THE
ADVISORY FOR THAT AREA HAS BEEN EXTENDED INTO THURSDAY MORNING. THE
WINDS WILL CONTINUE TO INCREASE AS THE FRONT PROCEEDS THROUGH THE
AREA AND LATER THIS AFTERNOON MORE WIND ADVISORIES MAY BE NEEDED FOR
THE ANTELOPE VLY AND I-5 CORRIDOR. OTHERWISE ONSHORE FLOW AND
LOWERING HGTS WILL KNOCK 4 TO 8 DEGREES OFF THE MAX TEMPS COMPARED
TO TUESDAY.

THE NORTH WINDS WILL PUSH SOME LOW CLOUDS UP AGAINST THE NORTH
SLOPES TONIGHT. SCALED WAY BACK ON LOW CLOUDS TONIGHT AS THE COLD
AIR SHOULD WIPE OUT THE INVERSION AND THE NORTH FLOW WILL KEEP ANY
CLOUDS THAT DO FORM PUSHED OUT TO SEA. IT WILL BE COLD THROUGH WITH
MOST LOWS IN THE INTERIOR DIPPING INTO THE MID TO UPPER 30S. IT WILL
BE WINDY ENOUGH TO PRECLUDE MOST NON MTN AREAS FROM SEEING FREEZING
TEMPS BUT THERE WILL BE ISOLATED FREEZES IN THE WIND SHELTERED AREAS
OF THE INTERIOR VLYS.

THURSDAY WILL BE MOSTLY SUNNY SAVE FOR THE NORTH SLOPES MTN CLOUDS.
IT WILL ALSO BE THE COOLEST OF THE NEXT 7 DUE TO A COMBINATION OF
LOW HGTS ANF STRONG ONSHORE FLOW. LOOK FOR MOST COASTAL AND VLY
TEMPS TO REACH ONLY INTO THE MID 60S.

THURSDAY NIGHT WILL BE CLEAR...COOL AND BREEZY. WIND ADVISORIES WILL
LIKELY BE NEEDED FOR MOST OF THE MTNS...THE SBA SOUTH COAST AND
MAYBE A FEW VLY LOCATIONS. WIND SHELTERED INLAND VLYS WILL SEE
ANOTHER ROUND OF FREEZING TEMPS AND THE FREEZE AREA SHOULD BE LARGE
THAN IT WILL BE TONIGHT.

THE TROF AXIS MOVES EASTWARD FRIDAY AND ALLOWS HGTS TO RISE AND
ONSHORE GRADIENTS TO RELAX. THIS WILL LEAD TO A SLIGHT WARMING TREND
BUT MAX TEMPS WILL BE A SLIGHTLY WARMER BUT STILL A FEW DEGREES
BELOW NORMAL.

.LONG TERM (SAT-TUE)...
AN INTERESTING SYNOPTIC PATTERN DEVELOPS FOR THE EXTENDED PERIOD.
ALL MEDIUM RANGE MDLS AGREE THAT A RIDGE CENTERED OVER TEXAS WILL
BULGE UP WHILE A COLD UPPER LOW IN THE PAC NW WILL PUSH SLIGHTLY
SOUTHWARD. SOUTHERN CALIFORNIA IS CAUGHT IN THE MIDDLE AND FROM SAT
TO MON THE UPPER FLOW WILL TILT MORE AND MORE TO THE SW WHILE AT THE
SAME TIME RISE IN HGTS. THERE WILL BE ONSHORE FLOW BUT IT WILL NOT
BE VERY STRONG. SO IT LOOKS LIKE THE FIRST NICE WEEKEND WE HAVE HAD
FOR A WHILE WITH SKIES REMAINING MOSTLY CLEAR AND MAX TEMPS JUMPING
UP ON SATURDAY AND THEN REMAINING ABOVE NORMAL THROUGH MONDAY.

ON TUESDAY THE UPPER LOW IS FORECAST TO SLOWLY APPROACH THE COAST.
THIS WILL LOWER HGTS AND INCREASE THE ONSHORE FLOW. MAX TEMPS WILL
DROP A FEW DEGREES TO NEAR NORMAL READINGS.

&&

ACROSS THE CENTRAL COAST. LGT TURBC OVER AND AROUND MTNS.
