AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
930 AM PDT THU MAR 29 2012

.SYNOPSIS...
WEAK RIDGING ALOFT WILL BRING MILD WEATHER TO SOUTHERN CALIFORNIA
TODAY AND FRIDAY.  THE COASTAL AND VALLEYS ZONES WILL SEE NIGHT AND
MORNING CLOUDS GIVE WAY TO AFTERNOON SUNSHINE.  A LOW PRESSURE
TROUGH WILL BRING COOLER WEATHER THIS WEEKEND...WITH A CHANCE FOR
LIGHT SHOWERS SATURDAY NIGHT AND SUNDAY MORNING.  THIS TROUGH WILL
ALSO BRING STRONG GUSTY WINDS TO THE MOUNTAINS AND DESERTS.  HIGH
PRESSURE WILL THEN BUILD BACK OVER THE REGION...WITH DRY AND WARMER
WEATHER FOR MONDAY THROUGH WEDNESDAY.

&&

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

WATER VAPOR IMAGERY CONTINUES TO SHOW A BROAD TROUGH OF LOW PRESSURE
OVER THE EASTERN PACIFIC THIS MORNING...WITH THE PARENT LOW OFF THE
BRITISH COLUMBIA COASTLINE.  THIS TROUGH IS SENDING A SERIES OF
STORMS INTO THE PACIFIC NORTHWEST AND THE NORTHWESTERN CALIFORNIA
COAST...WHICH IS TAPPING INTO SOME VERY MOIST SUBTROPICAL AIR.
ALTHOUGH THE MOISTURE WILL STAY WELL NORTH OF OUR AREA...PLENTY OF
HIGH CLOUDS WILL BE MOVING THROUGH SOUTHERN CALIFORNIA...AS SOUTHERN
CALIFORNIA REMAINS UNDER SOME WEAK RIDGING.  THEREFORE...EXPECT SOME
MINOR WARMING ACROSS THE REGION TODAY...AFTER THE LOW CLOUDS AND FOG
BURN OFF LATER THIS MORNING.  THE 12Z KNKX SOUNDING SHOWS THAT
MARINE LAYER DEEPENED TO NEAR 2000 FEET OVERNIGHT...TRIGGERING SOME
LIGHT DRIZZLE THIS MORNING ALONG THE COASTAL AREAS.  FURTHER
INLAND...THE VALLEYS ARE SEEING SOME PATCHY FOG...BUT VISIBILITIES
ARE STARTING TO IMPROVE.  DID A QUICK UPDATE TO TWEAK TRENDS THIS
MORNING...OTHERWISE...THINGS LOOK ON TRACK.

THE RIDGE WILL BUILD OVER SOUTHERN CALIFORNIA EVEN MORE SO ON
FRIDAY...AS THE TROUGH OF LOW PRESSURE DIGS OVER THE PACIFIC.
THEREFORE...EXPECT THE WARMING TREND TO CONTINUE INTO TOMORROW.
HOWEVER...THIS TROUGH WILL APPROACH THE WEST COAST THIS
WEEKEND...BRINGING SOME A CHANCE OF LIGHT PRECIPITATION TO THE
REGION LATE SATURDAY AND INTO SUNDAY.  THIS TROUGH WILL ALSO BRING
SOME STRONG AND GUSTY WINDS TO THE MOUNTAINS AND DESERTS.  AT THIS
TIME...IT LOOKS LIKE HIGH WINDS MAY BE POSSIBLE...AND WILL NEED TO
CONSIDER A HIGH WIND WATCH FOR THIS AFTERNOON.

HIGH PRESSURE WILL THEN BUILD BACK OVER THE REGION NEXT WEEK...WITH
DRY AND WARMER CONDITIONS PREVAILING.

&&

.AVIATION...
291515Z...STRATUS WITH BASES BETWEEN 800 AND 1500 FT MSL AND TOPS TO

3-5SM VSBY AND ISOLATED 2SM OR LESS WILL CONTINUE THROUGH ABOUT 18Z.
STRATUS WILL RETURN TO THE COASTAL AREAS AND WESTERN VALLEYS OF SAN
DIEGO COUNTY THIS EVENING WITH BASES AT/BELOW 700 FT MSL. WIDESPREAD
3-5SM VSBY IS LIKELY WITH LOCAL VSBY DOWN TO 1/4SM OVER HIGHER
COASTAL TERRAIN.

.MARINE...
A 4 TO 5 FOOT LONG PERIOD SOUTH SWELL WILL ARRIVE IN THE SOUTHERN
CALIFORNIA COASTAL WATERS LATE FRIDAY AFTERNOON. THIS WILL GENERATE
HIGH SURF ALONG SOUTH FACING BEACHES...UP TO 9-10 FEET IN ORANGE
COUNTY AND SLIGHTLY LOWER IN PORTIONS OF SAN DIEGO COUNTY FRIDAY
NIGHT INTO EARLY SATURDAY. A LARGE WNW SWELL WILL ENTER THE COASTAL
