SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
1015 PM PDT THU AUG 27 2009

UPDATED AVIATION DISCUSSION

.SYNOPSIS...
HIGH PRESSURE COVERS THE SOUTHWESTERN UNITED STATES AND HOT
TEMPERATURES WILL CONTINUE FOR OUR REGION INTO THE WEEKEND.
TEMPERATURES WILL COOL SOME NEXT WEEK AS THE HIGH PRESSURE WEAKENS
AND THE MARINE INFLUENCE STRENGTHENS.

&&

.SHORT TERM (TONIGHT-SUNDAY)...VERY HOT OVER THE DISTRICT TODAY WITH
MANY LOCATIONS TOPPING THE CENTURY MARK. THE HOTTEST OFFICIAL TEMP
WAS AT WOODLAND HILLS WITH 108 DEGREES. SEVERAL RECORD HIGHS WERE
BROKEN AS WELL INCLUDING LONG BEACH AT 103 DEGREES...AND SAN LUIS
OBISPO CAL POLY AT 102 DEGREES. PLEASE SEE LAXRERLOX FOR DETAILS ON
THE RECORD HIGHS TODAY FOR SOUTHWESTERN CA.

STILL VERY WARM THIS EVENING WITH MANY VALLEY AND FOOTHILL LOCATIONS
STILL IN THE LOW 90S. LATEST ACARS SOUNDING FROM LAX SHOWS A STRONG
MAINLY SURFACE BASED INVERSION WITH A MAX TEMP OF 93 DEGREES BETWEEN
1200 AND 1700 FT. TEMPS IN THE WARMEST FOOTHILL LOCATIONS WILL
LIKELY REMAIN IN THE 80S OVERNIGHT. SKIES OVER THE REGION WILL
REMAIN MOSTLY CLEAR THRU THE NIGHT...EXCEPT FOR SOME HI CLOUDS FROM
THE REMNANTS OF TROPICAL STORM IGNACIO MOVING INTO SLO/SBA COUNTIES
AT TIMES. SOME GUSTY NW TO N WINDS CAN BE EXPECTED TONIGHT ALONG THE
SBA S COAST AND MTNS AND THE L.A./VTU MTNS AROUND THE I-5
CORRIDOR...BUT WINDS SHOULD REMAIN GENERALLY BELOW ADVISORY LEVELS.

AN UPPER LEVEL HIGH IS FORECAST TO EXTEND FROM THE SOUTHERN GREAT
BASIN INTO SRN CA THRU SAT. A WEAK UPPER LEVEL TROUGH WILL THEN MOVE
INTO CENTRAL CA FOR SUN AS THE UPPER HI WEAKENS SOME. DRY AND HOT
CONDITIONS ARE EXPECTED TO PERSIST OVER THE FORECAST AREA THROUGH
THE PERIOD...ALTHO HI TEMPS BY SUN WILL BE DOWN A FEW DEGREES THANKS
TO INCREASED ONSHORE FLOW. IT ALSO LOOKS LIKE SOME MORE RECORD HIGH
TEMPS COULD BE BROKEN ESPECIALLY ON FRI...WITH READINGS INTO THE 102
TO 108 RANGE POSSIBLE OVER THE VALLEYS AND FOOTHILLS. EVEN THE
COASTAL PLAIN WILL CONTINUE WELL ABOVE NORMAL THRU SAT WITH READINGS
INTO THE UPPER 80S AND 90S AWAY FROM THE BEACHES. THE MARINE LAYER
SHOULD START TO DEVELOP AGAIN SAT NIGHT INTO SUN...ESPECIALLY ALONG
THE CENTRAL COAST...WITH SOME NIGHT AND MORNING LOW CLOUDS AND FOG.
OTHERWISE SKIES WILL CONTINUE MOSTLY CLEAR FOR THE MOST PART THRU
THE WEEKEND.

...FROM PREVIOUS DISCUSSION...

.LONG TERM (MON-THU)...MON CONTINUES THE COOLING TREND AS THICKS
FALL AND ONSHORE GRADS STRENGTHEN. EXPECTING A VLY PUSH OF THE
MARINE LAYER STRATUS...AND MAX AND MIN TEMPS WILL RETURN BACK TO
MORE SEASONABLE LEVELS. THIS IS ALL ENHANCED BY A WEAK LOW PRESSURE
AREA OFF THE NRN CA COAST THAT PUSHES OUR BATTERED RIDGE TO THE
SOUTHEAST. AS THE RIDGE MOVE TO THE EAST...SOUTHERLY FLOW ALOFT WILL
RETURN TO THE AREA...WHICH COULD PULL UP SOME MOISTURE. MODELS SHOW
A DEEP CLOSED LOW PARKING ITSELF OFF THE PAC NW ON WED...WHICH COULD
ACTUALLY HELP A RE-ESTABLISHED A RIDGE TO THE EAST THAT PUSHES
CLOSER TO SOCAL. BUMPED UP TEMPS WITH THIS IDEA...AS WELL AS AN
APPARENT OFFSHORE TREND. OF COURSE...MUCH CAN CHANGE UNTIL THEN.

&&

.AVIATION...29/0515Z...HI CONFIDENCE IN THE TAFS. SOME LOW LEVEL
WIND SHEAR CONDITIONS ARE POSSIBLE FOR A WHILE TONIGHT AT KSBA DUE
TO NORTH CANYON WINDS IN THE VICINITY. SOME SMOKE FROM THE FIRE NEAR
PALOS VERDES COULD BRIEFLY REDUCE VISIBILITIES NEAR KLGB AND POSSIBLY
KLAX OVERNIGHT AND FRI MORNING.

FOR KLAX...HI CONFIDENCE IN THE CURRENT TAF. THERE IS A 20 PERCENT
CHANCE THAT SMOKE FROM THE FIRE NEAR PALOS VERDES COULD REDUCE VSBYS
INTO THE MVFR RANGE OVERNIGHT/FRI MORNING.

FOR KBUR...HI CONFIDENCE IN THE CURRENT TAF.
