MARINE LAYER DEPTH AROUND 1500 TO 2000 FEET THIS EVENING OVER THE
DISTRICT. LOW CLOUDS WERE NOTED ALONG PORTIONS OF THE CENTRAL COAST AND
L.A. COUNTY COAST. ANOTHER WEAK EDDY IS EXPECTED TO FORM OVERNIGHT
WHICH WILL EXPAND THE LOW CLOUDS INLAND AND BACK UP THE COAST TO THE S
SBA COUNTY COAST LATE TONIGHT. LOW CLOUDS SHOULD MOVE BACK INTO THE
VTU/L.A. VALLEYS OVERNIGHT AS WELL.

DURING THE NEXT COUPLE OF DAYS...AN UPPER LEVEL HI CENTERED NEAR
NORTHERN BAJA TONIGHT IS EXPECTED TO BUILD SLOWLY NORTHEAST TO THE
FOUR CORNERS REGION BY SUN...WITH A RIDGE AXIS EXTENDING SW INTO SRN
CA. THRU SUNDAY 500 MB HEIGHTS/THICKNESSES/950 MB TEMPS INCREASE TO 
HELP SHRINK THE MARINE LAYER AND WARM TEMPERATURES...WITH HIGHS INLAND
BY SUN AFTERNOON REACHING WELL INTO THE 90S TO NEAR THE CENTURY MARK.
COASTAL AREAS WILL REMAIN UNDER THE INFLUENCE OF THE MARINE LAYER AND
MUCH COOLER THAN INLAND AREAS.

THE UPPER HI WILL REMAIN OVER THE WESTERN U.S. MON THRU WED...WITH A
SE FLOW ALOFT INTO SOCAL ESPECIALLY TUE AND WED. SOME MID LEVEL
MOISTURE IS EXPECTED TO BEGIN PUSHING INTO THE DISTRICT ON THIS
MONSOONAL TYPE FLOW TUE AND CONTINUE WED. THIS WILL RESULT IN THE 
CHANCE OF AFTERNOON AND EVENING THUNDERSTORMS OVER THE MOUNTAINS 
EACH DAY. OTHERWISE...HOTTEST TEMPS MON WITH SOME READING APPROACHING
RECORD LEVELS IN MANY INLAND AREAS. WITH SOME CLOUDINESS EXPECTED TO
MOVE IN TUE AND WED TEMPS MAY BE SLIGHTLY COOLER BUT STILL WELL ABOVE
NORMAL ACROSS THE DISTRICT. THE IMMEDIATE COAST WILL CONTINUE TO BE
THE COOLEST AREA AS MARINE LAYER CLOUDINESS MAY HANG ON STUBBORNLY 
PERHAPS INTO THE AFTERNOON IN SOME SPOTS. ISSUED A HAZARDOUS WEATHER
OUTLOOK FOR THE HOT WEATHER COMING UP UNDER THE PRODUCT LAXSPSLOX.

UPDATED THE FORECAST AROUND 800 PM TO ADJUST WORDING IN THE FIRST 
PERIOD FOR THE ONSET OF THE LOW CLOUDS AND FOG ALONG THE COAST...
