SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
851 PM PDT FRI JUN 7 2002

TODAY WAS OUR TRANSITION DAY IN TERMS OF THE BIG COOL-DOWN. INLAND
TEMPERATURES WERE AS MUCH AS 20 DEGREES COOLER THAN THURSDAY...THANKS
TO A DEEPER MARINE LAYER AND LATE BURN-OFF. ALL THIS DUE TO THE DEEP
UPR LOW SPINNING SLOWLY SOUTH ACROSS THE PAC NW STATES THIS EVENING.
THE UPR LOW WILL CONTINUE TO DROP ESE INTO THE NRN GREAT BASIN THROUGH
SATURDAY. A STRONG SHORTWAVE IS FORECAST TO ROUND THE BASE OF THE
AMPLIFYING TROUGH...PASSING JUST TO OUR NORTH SUNDAY MORNING. SO
THROUGH SUNDAY WE CAN EXPECT STRONG ONSHORE FLOW TO PERSIST WITH A
RELATIVELY DEEP SFC LOW PRESENT OVR THE GREAT BASIN. WINDS WILL BE
RATHER STRONG FROM THE CENT COAST THROUGH THE MTNS AND ACROSS THE
DESERT SATURDAY AND SUNDAY...ALTHOUGH SUNDAYS WINDS WILL BECOME MORE
NORTHERLY THROUGH THE CENT COAST IN THE WAKE OF THE SHORTWAVE.
HOWEVER...CURRENT FCST OF 30 TO 40 MPH WINDS IN THE ANTELOPE VALLEY
SATURDAY AFTERNOON WILL REQUIRE THE ISSUANCE OF A WIND ADVISORY AT
SOME POINT IN THE NEXT 12 OR SO HOURS.

MARINE LYR CURRENTLY AROUND 2000 FEET ON THE COAST AND NEAR 2500 FEET
DEEP IN THE VALLEYS. EXPECT THE LOW CLOUDS TO FILL IN ALL THE WAY TO
THE MTNS OVERNIGHT...WITH SOME DEVELOPMENT ALSO ON THE CENT COAST.
WITH THE SLIGHT HEIGHT FALLS AND SATURATED LOW LEVELS...ANY WEAK LIFT
COULD GENERATE SOME DRIZZLE...SO WILL ADD THAT TO THE ZONES FOR THE
OVERNIGHT AND MORNING PERIOD. SHOULD HAVE ANOTHER LATE BURN-OFF
SAT...SO EXPECT TEMPS TO BE NEAR THE SAME OR SLIGHTLY COOLER THAN
TODAY IN THE VALLEYS. INVERSION TEMPS HAVE COOLED QUITE A BIT OVER THE
PAST FEW DAYS...SO MTNS WILL EXPERIENCE A CONTINUED COOLING.

IN THE EXTENDED...UPR LOW LIFTS OFF TO THE NORTHEAST MONDAY AND A
GENERAL WEAK SW FLOW DEVELOPS OVR SRN CA AS HEIGHTS ONLY RISE
SLIGHTLY. HOWEVER...WITH THE WEAKENING OF ONSHORE FLOW...TEMPS SHOULD
WARM BACK UP INLAND...ALTHOUGH NOT AS HOT AS THE PAST FEW DAYS.
