AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
914 PM PST FRI DEC 23 2005

.SYNOPSIS...FAIR WEATHER WILL PREVAIL THROUGH SUNDAY...EXCEPT FOR
AREAS OF LOW CLOUDS AND FOG NEAR THE COAST AT TIMES. DEVELOPING
HIGH PRESSURE AND WEAK OFFSHORE FLOW WILL BRING WARMER WEATHER
SATURDAY BEFORE A COOLING TREND BEGINS SUNDAY DUE TO ONSHORE FLOW.
AN UPPER TROUGH WILL MOVE THROUGH MONDAY OR MONDAY NIGHT FOR MORE
COOLING AND CLOUDS. GENERALLY FAIR AND WARMER FOR MIDWEEK. THEN
ANOTHER TROUGH BRINGS COOLING AND MORE CLOUDS BY THURSDAY.
TEMPERATURES ARE EXPECTED REMAIN MOSTLY ABOVE SEASONAL NORMALS MOST
OF NEXT WEEK...AS THE STORM TRACK STAYS TO THE NORTH.

&&

.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...

AREAS OF DENSE FOG DEVELOPED RAPIDLY THIS EVENING NEAR THE COAST AND
SPREAD INLAND EVEN AS OFFSHORE WINDS WERE DEVELOPING ABOUT 2K FT
ABOVE THE SURFACE. LATEST ACARS SOUNDINGS OUT OF LINDBERGH FIELD
INDICATE A STRONG LOW LEVEL INVERSION HAS FORMED. AT 0337Z A TEMP OF
24 DEGREES C WAS OBSERVED AT 1.3K FT. ABOVE THE INVERSION NORTHEAST
WINDS OF 20 TO 25 KTS WERE OBSERVED. SOME SURFACE OBSERVATIONS
FARTHER INLAND ALREADY HAVE NE WINDS GUSTING TO OVER 20 MPH. WEAK TO
NEUTRAL SURFACE PRESSURE GRADIENT TRENDS CONTINUE OVER SAN DIEGO
COUNTY...BUT ARE GENERALLY OFFSHORE WITH STRONG OFFSHORE TRENDS.

ONCE AGAIN WE HAVE A DIFFICULT FORECAST SITUATION FOR COASTAL AREAS.
SUPPORT TO DRIVE THE E FLOW TO THE SURFACE AT THE COAST IS NON
EXISTENT. THE LATEST NAM MODEL TIME/HEIGHT CROSS SECTION ALSO KEEPS
A VERY SHALLOW LAYER OF MOISTURE THERE AS WELL. WITH THE STRONG
INVERSION NOW IN PLACE...IT COULD BE ONE OF THOSE SITUATIONS WHERE
WE GET THE VERY LOW STRATUS AND FOG TRAPPED NEAR THE COAST ALL
NIGHT...EVEN AS WARMER OFFSHORE WINDS BLOW JUST ABOVE THE SURFACE.
WITH THAT IN MIND A DENSE FOG ADVISORY WAS ISSUED UNTIL 8 AM SAT
MORNING. THERE IS A GOOD CHANCE THAT THE FOG AND LOW CLOUDS COULD
MOVE OFFSHORE LATE TONIGHT IN SOME AREAS IF THE WINDS ARE ABLE TO
MIX DOWN A FEW MORE HUNDRED FEET. CERTAINLY MIXING TOMORROW MORNING
SHOULD BE ABLE TO BREAK UP ANY REMAINING FOG. IN THE MEANTIME IT
COULD BECOME QUITE DENSE OVER BEACH AND COASTAL AREAS TONIGHT.

ANOTHER POTENTIAL PROBLEM IS THE WINDS. AT THIS POINT...OUR LOCAL
WIND PROGRAM BASED ON THE NGM AND NAM MODELS SHOWS VERY MARGINAL
WIND ADVISORY GUSTS IN THE SANTA ANA MOUNTAINS. THIS SEEMS
REASONABLE BASED ON GOOD OFFSHORE SURFACE TRENDS AND WEAK UPPER
SUPPORT. AT THIS POINT FEEL ANY ADVISORY LEVEL WINDS WOULD BE VERY
LOCALIZED.

THE LATEST NAM MODEL IS MORE BULLISH WITH THE TROUGH ON MON AND MON
NIGHT WITH TIME/HEIGHT CROSS SECTIONS MOISTENING ENOUGH FOR SOME
LIGHT RAIN BY MON NIGHT. WILL HAVE TO WAIT FOR CONFIRMATION FROM THE
GFS AND SUBSEQUENT RUNS TO SEE IF POPS NEED TO BE ADDED TO THE ZONE
FORECASTS. BEYOND MON...ANOTHER RIDGE BUILDS FOR DRY AND MILD
WEATHER THROUGH THE MIDDLE OF NEXT WEEK.

A ZONE FORECAST UPDATE WAS ISSUED EARLIER THIS EVENING...AND NO
FURTHER UPDATES ARE EXPECTED AT THIS TIME.

&&

.AVIATION...SHALLOW MARINE LAYER CONTINUES TO PLAGUE THE COAST WITH
DENSE FOG AND IFR VIS. MARINE LAYER ABOUT 800 FEET. OFFSHORE FLOW
EXPECTED TO CLEAR OUT THE COAST BY SUNRISE IF NOT SOONER. NORTHEAST
WINDS BEGAN EARLY TONIGHT AT ONTARIO AND HAVE SLOWLY MOVED TOWARD
THE COAST. MARINE LAYER SHOULD BE CLEARED OUT SATURDAY AND NOT
EXPECTING A RETURN AT NIGHT. WINDS ALOFT...NORTHEAST TO EAST 10 TO
15 KT THROUGH SATURDAY...BECOMING LIGHT EAST TO SOUTHEAST AFTERNOON.
