SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
345 AM PDT WED MAY 6 2009

.SHORT TERM...
NW WIND EVENT WILL PEAK TODAY AND TONIGHT...BUT WINDY CONDITIONS
WILL LAST THROUGH FRIDAY. STRONG NW FLOW ALOFT IS NICELY ALIGNED
WITH A STRONG NW TO SW SFC GRADIENT. BETTER SUBSIDENCE THIS
AFTERNOON WILL DRIVE STRONGER WINDS ALOFT DOWN TO THE SURFACE. IT IS
POSSIBLE THAT 65 MPH GUSTS WILL OCCUR OVER THE SOUTHERN PORTION OF
SBA COUNTY AND A HIGH WIND WATCH IS IN EFFECT FOR THE AREA FROM 3PM
TO 9AM THURSDAY. WIND ADVISORIES CONTINUE IN THE MTNS OF VTA AND LA
COUNTIES AND A NEW ADVISORY HAS BEEN ISSUED FOR THE CENTRAL COAST.
LATER THIS AFTERNOON THE ANTELOPE VLY AND THE SANTA CLARITA VLY MAY
NEED ADVISORIES AS WELL. 586DM HGTS OVERHEAD WILL ALLOW VERY WARM
TEMPS INLAND BUT THERE WILL BE SEA BREEZES SO THE COASTS WILL STAY
RELATIVELY COOL...WITH THE NOTABLE EXCEPTION OF THE SBA SOUTH COAST
WHERE HIGHS WILL REACH INTO THE UPPER 80S AND PERHAPS THE LOWER 90S.

CONTINUED WINDY TONIGHT. THE FOOTHILLS AND THE WINDY AREAS WILL SEE
LOWS FALL ONLY TO THE LOWER 70S.

THURSDAY WILL BE JUST AS WARM AS TODAY. BUT THERE IS LESS SUBSIDENCE
AND THIS WILL DROP THE WINDS BY AROUND 10 MPH. THE SEABREEZES WILL
KEEP THE COASTAL TEMPS LOW. MARINE LAYER CLOUDS SHOULD BE MIXED OUT
SO ALL AREAS WILL BE SUNNY.

FRIDAY WILL BE LESS WINDY AS THE LAX-BFL GRADS TREND ONSHORE BY
ABOUT 1.5 MB. THE UPPER FLOW WEAKENS SOME AS WELL. HGTS DROP A
COUPLE OF DM AND THE GRAD TO KDAG INCREASES WHICH WILL PROMOTE A
BETTER SEABREEZE. THESE TWO ITEMS WILL COMBINE TO DUMP TEMPS A FEW
DEGREES. THE SBA SOUTH COAST WILL SEE THE BIGGEST COOLING.

ONE THING OF INTEREST ON FRIDAY THE NAM HAS A SLAMMING OFFSHORE
EVENT OVER THE CENTRAL COAST ON FRIDAY. THE NAM HAS BEEN A LITTLE
WONKY OF LATE WITH ITS LOW LEVEL FCST AND HAVE DISCOUNTED IT FOR
NOW. STILL HAVE TO BE WATCHFUL BECAUSE IF IT DOES HAPPENED BOTH LOW
AND HIGH TEMPS WILL NEED ABOUT A 15 DEGREE INCREASE.

.LONG TERM...
GFS AND EC CONTINUE TO AGREE ON MOST ASPECTS OF THE LONG RANGE
FORECAST AND CONFIDENCE IN THE GENERAL PATTERN IS QUITE HIGH. THE
RIDGE BEGINS TO FLATTEN SATURDAY AND SUNDAY BUT HGTS STILL STAY
FAIRLY HIGH. A COUPLE OF DEGREES OF COOLING INLAND. THERE IS NOTHING
AROUND TO LIFR UP A MARINE LAYER AND KEPT SKIES CLEAR THROUGH THE
WEEKEND BUT DO NOT HAVE ABSOLUTE CONFIDENCE IN THAT AS GALES IN THE
OUTER WATERS COULD SPIN UP AN EDDY.

GOOD COOLING BEGINS EARLY NEXT WEEK AS AN UPPER LOW SPINS INTO THE
PAC NW AND KNOCKING THE RIDGE AWAY AND SETTING UP BROAD CYCLONIC
FLOW OVER THE AREA AS WELL AS LOWERING HGTS TO 572DM BY TUESDAY
AFTERNOON. LOOK FOR TEMPS TO PLUMMET TO NEAR NORMAL AND A GOOD
VALLEY PENETRATING MARINE LAYER TO SPIN.
