.SHORT TERM (TODAY-TUE)...6000+ FT MARINE/MOIST LAYER CONTINUES
TODAY WITH CLOUDS WELL UP THE COASTAL MTN SLOPES. AT THE SAME TIME
WEVE GOT LOWER CEILINGS ALONG THE COAST ASSOCIATED WITH A SECOND
AND LOWER INVERSION WITH SOME PATCHY FOG AND DRIZZLE. DONT SEE MUCH
CHANGING TODAY FROM SAT WITH REGARD TO SKY CONDITIONS. PROFILERS
GENERALLY RUNNING A COUPLE DEGREES COOLER AND GRADIENTS ARE STRONGER
ONSHORE SO IT SHOULD BE A LITTLE COOLER IN MOST AREAS.

INCREASING ONSHORE FLOW TODAY WILL ENSURE ANOTHER DAY OF GUSTY WINDS
IN THE ANTELOPE VALLEY. WINDS ALREADY PICKING UP THIS MORNING AND
MIGHT HAVE TO CONSIDER A WIND ADVISORY THIS AFTERNOON.

A REMNANT CIRCULATION FROM AN OLD TROPICAL STORM IS SPINNING ABOUT
500 MILES SOUTHWEST OF LAX AND DRIFTING SLOWLY NORTH. MODELS
CONTINUE TO WEAKEN IT AND STRETCH IT OUT AS THE TROF ALONG THE WEST
COAST DEEPENS MONDAY AND TUESDAY. NOT SURE EXACTLY WHAT IMPACT THIS
WILL HAVE FOR US BUT AT BEST THERE WILL BE LITTLE CHANGE AND AT
WORSE IT COULD INSTIGATE A LITTLE MORE WIDESPREAD DRIZZLE.

AS PREVIOUS SHIFTS INDICATED THE AIRMASS GETS CONSIDERABLY DRIER
TUESDAY AS SOUTHERLY FLOW SHIFTS TO NORTHWEST BEHIND THE TROF.
AROUND THIS SAME TIME NORTHWEST FLOW WILL BE INCREASING ALONG OUR
COASTAL WATERS, WHICH LIKELY WILL INDUCE MORE COASTAL UPWELLING AND
A SIGNIFICANT DROP IN SSTS. IN TURN, WE SHOULD SEE OVERNIGHT LOWS
DROPPING TO MORE NORMAL LEVELS AND DAYTIME HIGHS WILL BE COOLER AS
WELL.

.LONG TERM (WED-SAT)...NOT MUCH CHANGE THROUGH THE LATTER PORTION OF
THE WEEK INTO NEXT WEEKEND. LONG WAVE TROF REMAINS IN PLACE WITH A
DRY WEST TO SOUTHWEST FLOW ALOFT. A FEW LITTLE IMPULSES WILL PASS
THROUGH THE TROF FROM TIME TO TIME, POSSIBLY CAUSING SOME ISOLATED
DRIZZLE DURING THE LATE NIGHT/EARLY MORNING HOURS. OTHERWISE, EXPECT
THIS DEEP MARINE LYR PATTERN TO CONTINUE SOUTH OF PT CONCEPTION WITH
PARTLY CLOUDY SKIES BY AFTERNOON.

&&

.AVIATION...UPPER LEVEL HIGH CENTERED OVER AZ WITH A WEAK TROUGH
CENTERED ALONG 125W AND MODERATE S FLOW OVER THE AREA. UPPER LEVEL
MOISTURE WILL CONTINUE TO STREAM N WELL OFFSHORE TODAY THEN BEGIN TO
SHIFT EAST MON MORNING AS A TROUGH OFF THE PAC NW APPROACHES NRN CA.
RELATIVELY DEEP LOW LEVEL MOISTURE WILL PERSIST OVER THE AREA WITH
CLOUD TOPS NEAR 6.2KFT. NW LOW LEVEL FLOW WILL ACCELERATE OVER THE
COASTAL WATERS NORTH OF POINT CONCEPTION OVERNIGHT IN RESPONSE TO
THE PACIFIC HIGH BUILDING EAST AND LOW CLOUDS WILL MIX OUT WITHIN
THE THE DESCENDING FLOW ALONG THE SLO/SB COUNTY COAST MON MORNING.
CATALINA EDDY WILL DEVELOP OVERNIGHT AS WELL AND LOW CLOUDS WILL
PERSIST NEARSHORE AS WELL AS OVER THE COASTAL VALLEYS. MEX/MAV WERE
SIMILAR THOUGH HAVE DEVIATED AND INDICATED LOWER CIGS ESPECIALLY
NORTH OF POINT CONCEPTION MON MORNING AS WELL AS INDICATED VFR
CONDITIONS THIS AFTERNOON.
