SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
230 PM PST WED FEB 6 2002

FOR THE NEXT 48 HOURS...WILL STICK WITH PATCHY FOG AGAIN TONIGHT.
THURSDAY WILL BE ANOTHER RELATIVELY COOL DAY WITH COOLING 850 MB TEMPS
AND DROPS IN THICKNESS. THE INCREASED ONSHORE FLOW WILL FOCUS MOST
COOLING IN COASTAL SECTIONS...HOWEVER TEMPS WILL LIKELY GO DOWN IN ALL
SECTIONS. THE MARINE LAYER WILL BECOME A BIT MORE EXTENSIVE THURSDAY
NIGHT AND FRIDAY MORNING...WITH THE POSSIBILITY OF LOW CLOUDS REACHING
THE LOWER VALLEYS FRIDAY MORNING. IN ADDITION...THE LATEST AVN WAS
SHOWING SOME CLOUDS MOVING INTO NORTHERN SECTIONS THURSDAY NIGHT
ASSOCIATED WITH ONE OF THE TROUGHS AFFECTING NORTHERN PORTIONS OF THE
STATE. THE RIDGE ALOFT WILL START TO BUILD AGAIN LATE FRIDAY...SO
TEMPERATURES COULD START TO INCREASE IN THE MTN AND DESERT SECTIONS
FRIDAY. THE ONSHORE FLOW WITNESSED ON THURSDAY BECOMES MORE NORTHERLY
FRIDAY AFTERNOON...EXPOSING SBA COUNTY MTNS AND SOUTH COAST...THE
SANTA CLARITA/SAN FERNANDO VALLEYS AND THE CENTRAL COAST TO SOME GUSTY
NORTH/NORTHWEST WINDS AS THE LAX-SFO GRADIENT INTENSIFIES TO NEAR -7
MB.

FOR THE EXTENDED...THE RIDGE ALOFT BUILDS RATHER STRONGLY INTO SOCAL 
OVER THE WEEKEND...AND AT THE SAME TIME SURFACE HIGH PRESSURE BUILDS
INTO THE GREAT BASIN...CAUSING ANOTHER LOW LEVEL FLOW REVERSAL...THIS
TIME TO OFFSHORE FLOW. THEREFORE...THE MARINE INFLUENCE WILL BE 
REDUCED YET PROBABLY NOT ELIMINATED WITH PATCHY LOW CLOUDS HANGING 
NEAR THE COAST. COOLER TEMPERATURES ARE DUE AGAIN EARLY NEXT WEEK AS
THE RIDGE STARTS TO BREAK DOWN ONCE AGAIN.

LAX 0000. SWEET.
