AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
930 AM PDT FRI OCT 3 2008

.SYNOPSIS...A TROUGH OF LOW PRESSURE APPROACHING THE WEST COAST WILL
BRING INCREASING ONSHORE FLOW AND COOLER WEATHER THROUGH SATURDAY.
THERE IS A SLIGHT CHANCE OF RAIN LATE SATURDAY THROUGH EARLY SUNDAY
MORNING FROM THE MOUNTAINS WEST TO THE COAST DUE TO A WEAK COLD
FRONT AND MOIST UPSLOPE FLOW. WINDY CONDITIONS WILL OCCUR OVER THE
MOUNTAINS AND DESERTS AT TIMES OVER THE WEEKEND...ESPECIALLY
SATURDAY EVENING. FAIR AND MUCH WARMER WEATHER IS EXPECTED EARLY
NEXT WEEK AS HIGH PRESSURE REBUILDS ALOFT AND SURFACE FLOW TURNS
OFFSHORE.

&&

.DISCUSSION...FOR SOUTHWEST CALIFORNIA INCLUDING SAN DIEGO...
ORANGE...SOUTHWEST SAN BERNARDINO AND WEST RIVERSIDE COUNTIES.

THE MARINE LAYER DEPTH INCREASED TO 1500 FT THIS MORNING AND PATCHY
STRATUS HAS SPREAD INTO THE VALLEYS. TEMPS WILL BE ABOUT 10 DEGREES
COOLER TODAY AS A TROUGH OF LOW PRESSURE MOVES INTO THE WEST COAST.
IT WILL CONTINUE TO BE BREEZY ON THE MOUNTAIN CRESTS/PASSES AND
DESERTS AS WESTERLY WINDS ALOFT INCREASE AHEAD OF THIS TROUGH.

IT WILL BE EVEN COOLER SATURDAY AS THE TROUGH MOVES THROUGH THE
AREA. THE MARINE LAYER IS EXPECTED TO DEEPEN OVERNIGHT INTO SATURDAY
MORNING AHEAD OF AN APPROACHING FRONT...AND THERE COULD BE SOME
PATCHY DRIZZLE AS THIS HAPPENS. MOIST UPSLOPE FLOW COULD EVEN CAUSE
A FEW EARLY MORNING SHOWERS ALONG THE COASTAL MOUNTAIN SLOPES...BUT
THE MAIN WEATHER CONCERN UP THERE WILL BE THE DENSE FOG AND GUSTY
WINDS. SOME BREAKS IN THE CLOUDS MAY DEVELOP BY LATE MORNING AND
EARLY AFTERNOON...ESPECIALLY IN COASTAL SAN DIEGO COUNTY...AND WE
COULD EVEN SEE A BRIEF REVERSE CLEARING TYPE PATTERN. THE CLOUDS
WILL QUICKLY FILL IN THOUGH AS A DECAYING FRONT MOVES ACROSS THROUGH
ORANGE/SW SBD COUNTIES IN THE LATE AFTERNOON AND SAN DIEGO COUNTY IN
THE EVENING. THE AIRMASS BELOW 700 MB WILL BRIEFLY BECOME SATURATED
AS THE FRONT MOVES THROUGH AND THIS COULD BRING A FEW LIGHT SHOWERS
TO THE AREA...MAINLY SATURDAY EVENING/NIGHT. HOWEVER...THE FRONT
WILL BE FAST MOVING AND WILL NOT HAVE MUCH UPPER-LEVEL SUPPORT BY
THE TIME IT ARRIVES...SO RAINFALL WILL BE SPORADIC AND LIGHT.
AMOUNTS WILL GENERALLY AVERAGE AROUND 1/10 OF AN INCH...EXCEPT
LOCALLY AROUND 2/10 OF AN INCH ON THE LOWER COASTAL SLOPES. MANY
LOCATIONS IN SOUTHERN SAN DIEGO COUNTY ALONG THE COAST AS WELL AS
INTERIOR PORTIONS OF THE INLAND EMPIRE ALONG THE 215 BETWEEN
MURRIETA AND MARCH FIELD MAY ONLY SEE A FEW HUNDREDTHS. NO RAIN IS
EXPECTED IN THE DESERTS. PRECIP SHOULD END FAIRLY FAST WITH SHOWERS
NOT EXPECTED TO LINGER MUCH PAST SUNRISE SUNDAY.

THE BIGGER WEATHER STORY ON SATURDAY WILL BE THE COOLER TEMPS AND
THE GUSTY WINDS IN THE MOUNTAINS AND DESERTS. TEMPS WILL BE 10
DEGREES BELOW AVERAGE ALONG THE COAST...AND AS MUCH AS 15-20 DEGREES
BELOW AVERAGE INLAND. RATHER STRONG WEST WINDS IN THE 850-700 MB
LAYER WILL CAUSE LOCALLY WINDY CONDITIONS IN THE MOUNTAINS AND
DESERTS SATURDAY AFTERNOON THROUGH EARLY SUNDAY MORNING. LOCAL WIND
GUSTS TO 50 MPH WILL BE POSSIBLE...ESPECIALLY ON THE DESERT
SLOPES...AND MOUNTAIN WAVE ACTIVITY IS LIKELY. A WIND ADVISORY WILL
BE NEEDED.

FAIR WEATHER WITH LITTLE OR NO MARINE LAYER SHOULD RETURN EARLY NEXT
WEEK DUE TO UPPER LEVEL RIDGING AND WEAK OFFSHORE FLOW. TEMPS SHOULD
PEAK ABOVE AVERAGE TUE/WED IN MOST AREAS AS OFFSHORE FLOW CONTINUES
AT THE SURFACE AND A 500 MB HEIGHTS RISE TO AROUND 590 DAM. MORE
COOLING AND ONSHORE FLOW WILL RETURN THE LATTER HALF OF NEXT WEEK AS
ANOTHER UPPER TROUGH MOVES OVER THE WEST COAST. WITH A STRONG UPPER
LOW OVER ALASKA SENDING TROUGHS TO THE SE INTO THE W US...WE SHOULD
BE IN A HIGH-AMPLITUDE PATTERN FOR A FEW WEEKS. THAT TYPICALLY
RESULTS IN CHANGEABLE WEATHER EVERY FEW DAYS...WITH A GREATER THAN
AVERAGE PROBABILITY OF A SYSTEM DEEP ENOUGH TO PRODUCE PRECIP HERE.

&&

.AVIATION...
031430Z...MARINE LAYER DEEPENED TO AROUND 2000 FEET THIS MORNING AND
SHOULD DEEPEN TO AROUND 4000 FEET BY SATURDAY MORNING. AREAS OF
STRATUS WHICH IS MAINLY CONFINED TO THE COAST AND SOME INLAND VALLEY
AREAS SHOULD BREAK UP BY 18Z TODAY...LIKELY TO BE SCATTERED...THEN
FILL BACK IN AFTER SUNSET AND SPREAD INTO THE COASTAL SLOPES
OVERNIGHT. BASES SHOULD BE AROUND 1500 FEET MSL THIS AFTERNOON AND
TONIGHT. BASES SHOULD LIFT TONIGHT AND SATURDAY TO AROUND 2000 FEET.
SOME VISIBILITY RESTRICTIONS IN FOG AND DRIZZLE WEST OF THE
MOUNTAINS TONIGHT. A WEAK COLD FRONT WILL PASS THROUGH SATURDAY
EVENING WITH SHOWERS.

ABOVE THE MARINE LAYER...MOSTLY CLEAR THROUGH THE AFTERNOON WITH
SOME INCREASE IN MID AND HIGH CLOUDS TONIGHT INTO SATURDAY. BASES OF
THE MID CLOUDS SHOULD BE ABOVE FL120 TONIGHT LOWERING TO FL080
SATURDAY. VISIBILITIES SHOULD REMAIN UNRESTRICTED THROUGH SATURDAY
AFTERNOON.  HORTON

&&

.FIRE WEATHER...
NO PROBLEMS IN THE SHORT TERM...TODAY THROUGH SUNDAY. COOLING AND
MOISTENING TREND WELL UNDERWAY AND THOUGH WINDS LIKELY TO GUST WELL
OVER 35 MPH IN DESERT AND MOUNTAINS...THE RELATIVE HUMIDITY WILL
REMAIN ABOVE 20 PERCENT. WILL DISCUSS THE LONGER RANGE IN THE
AFTERNOON DISCUSSION.
