SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
503 AM PDT TUE JUN 19 2012

UPDATED AVIATION SECTION

.SYNOPSIS...

ONSHORE FLOW WILL PERSIST AND BRING NIGHT AND MORNING LOW CLOUDS AND
FOG AT THE BEACHES AND VALLEYS. HIGH PRESSURE WILL BRING WARMER
AFTERNOON TEMPERATURES INLAND ON WEDNESDAY. A LOW WILL MOVE IN
THURSDAY TO INCREASE THE MARINE LAYER AND LOWER AFTERNOON
TEMPERATURES TO BELOW NORMAL THROUGH TUESDAY.

&&

.SHORT TERM (TODAY-FRI)...
MARINE LAYER IS AT 2200 FEET AND DRIVEN BY A VERY STRONG 9 MB PUSH
TO KDAG LOW CLOUDS HAVE PUSHED INTO ALL COASTS AND VLYS. CLEARING
WILL BE SLOW TODAY ACROSS THE VLYS AND LIKELY NON EXISTENT ACROSS
THE COASTS. THE BIG ONSHORE PUSH WILL BRING WIND ADVISORY LEVEL
GUSTS TO ANTELOPE VLY THIS AFTERNOON AND EVENING. A UPPER HIGH OVER
MEXICO WILL SLOWLY PUSH NORTHWARD INTO SOUTHERN CA TODAY. THIS WILL
ALLOW FOR SOME WARMING ACROSS THE MTNS AND DESERTS...BUT THE GLOOMY
MARINE LAYER WILL KEEP THE COASTAL VLY TEMPS FROM SEEING MUCH IF ANY
CHANGE FROM YDYS VALUES IN FACT THE VLYS MIGHT COOL A FEW DEGREES.

NOT TOO MUCH CHANGE FOR WEDNESDAY. THE UPPER HIGH CONTINUES TO MOVE
INTO SOUTHERN CALIFORNIA AND HGTS WILL PEAK. THE BUILDING UPPER HIGH
WILL FURTHER STRENGTHEN THE INVERSION AND WITH THE STRONG ONSHORE
FLOW THERE WILL BE ANOTHER GLOOMY DAY ACROSS THE COASTS AND VLYS.
ANOTHER DEGREE OR TWO OF WARMING IN THE MTNS AND DESERTS. VLY TEMPS
WILL BE TRICKY AND COULD VARY QUITE A BIT FROM LOCATION TO LOCATION
DEPENDING ON WHERE THE CLOUDS DO BURN OFF AND WHEN.

SUMMER OFFICIALLY BEGINS AT 409 PM PDT WEDNESDAY AFTERNOON.

ON THURSDAY A LARGE COOL UPPER LOW WILL BEGIN ITS MOVE OUT OF THE
GULF OF ALASKA THIS UPPER LOW WILL BE THE MAIN INFLUENCE OF THE
WEATHER THROUGH MONDAY. AS THE UPPER LOW MOVES SOUTHWARD IT WILL
GOBBLE UP THE CUT OFF LOW THAT WAS OVER US ON SATURDAY. IT WILL OPEN
UP LOW INTO A TROF AND MOVE IT OVER THE AREA. THIS WILL KEEP THE
MARINE LAYER GOING BUT THE LOWER HGTS WILL ALLOW FOR COOLING INLAND.

ON THURSDAY NIGHT A GOOD NORTH TO SOUTH OFFSHORE FLOW SETS UP. THE
MAIN FORECAST DILEMMA WILL BE TO DECIDE IF THE OFFSHORE WINDS WILL
RIDE OVER THE MARINE LAYER OR WILL IT DRIVE AND MIX THE MARINE
CLOUDS OUT. CURRENT MDL FCST SHOWS GOOD CLEARING IN THE VLYS AND THE
SBA SOUTH COAST WHERE THERE WILL BE A MODERATE SUNDOWNER. TRENDED
THE FORECAST TO THE CLEARER SOLN AND KEPT THE VLYS MOSTLY CLEAR
ALONG WITH THE SBA SOUTH COAST. THERE IS A CHC THAT THIS IS THE
WRONG FCST AND THAT THE NORTH WINDS WILL NOT DEVELOP AND THE TROF
WILL LIFT THE MARINE LAYER DEEP INTO THE VLY WITH ENOUGH LIFT TO
PRODUCE SOME DRIZZLE SO THIS WILL BE THE PERIOD OF THE FCST THAT
NEED THE MOST ATTENTION.

THE OFFSHORE PUSH SHOULD ALLOW FOR THE FIRST DECENT CLEARING DAY OF
THE WEEK. THE LOWER HGTS WILL NOT ALLOW FOR MUCH WARMING ALONG THE
COAST DESPITE THE ADDED SUNSHINE. THE INLAND AREAS WILL COOL A
COUPLE OF DEGREES.

.LONG TERM (SAT-MON)...
THE EXTENDED FORECAST LOOKS LIKE THREE CONSECUTIVE DAYS OF TYPICAL
JUNE WEATHER. THE BIG UPPER LOW JUST SITS TO THE WEST OF OREGON AND
SPINS. THIS WILL KEEP SOCAL UNDER RELENTLESS CYCLONIC FLOW ALOFT AND
ONSHORE FLOW AT THE SFC. THERE WILL BE NIGHT THROUGH MORNING LOW
CLOUDS OVER THE COASTS AND VLYS (NOT THE SANTA CLARITA) MAX TEMPS
WILL BE A FEW DEGREES BLO NORMAL FOR THE CSTS/VLYS BUT THE INLAND
AREAS WILL BE NEAR NORMAL AS THE HGTS WILL STILL BE NEAR 585 DM.
