AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
135 PM PDT TUE MAR 19 2013

.SYNOPSIS...
UPPER LEVEL MOISTURE FROM THE WEST WILL CONTINUE TO BRING NUMEROUS
HIGH CLOUDS OVER THE AREA THROUGH WEDNESDAY...WHILE PATCHY LOW
CLOUDS WILL BE POSSIBLE WEST OF THE MOUNTAINS DURING THE NIGHTS AND
MORNINGS. FOR WEDNESDAY EVENING THROUGH EARLY THURSDAY
MORNING...GUSTY AND LOCALLY STRONG WEST WINDS TO THE MOUNTAINS AND
DESERTS. WIDESPREAD STRATUS WILL FORM DEEP INTO THE INLAND VALLEYS
THURSDAY NIGHT INTO FRIDAY MORNING...BUT THEN THE MARINE LAYER WILL
GET CLEARED OUT FRIDAY NIGHT DUE TO WEAK TO MODERATE OFFSHORE FLOW.
TEMPERATURES WILL REMAIN AROUND SEASONAL NORMALS...WITH FAIRLY
BENIGN WEATHER CONTINUING THROUGH EARLY NEXT WEEK.

&&

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

STRATUS FROM THIS MORNING HAS FINALLY CLEARED OUT TO THE COASTAL
WATERS THIS AFTERNOON ACCORDING TO VISIBLE SATELLITE. MEANWHILE
ALOFT...PLENTIFUL HIGH CLOUDS CONTINUE TO MOVE IN FROM THE PACIFIC.
THE HIGH CLOUDS SHOULD THICKEN THROUGH TOMORROW...AND LIKELY
INTERFERE WITH STRATUS FORMATION INTO THE INLAND VALLEYS OVERNIGHT
TONIGHT. THIS MAY BE WHY THE LOCAL WRF SHOWS PATCHY STRATUS AT BEST
INTO THE INLAND VALLEYS FOR TONIGHT/TOMORROW MORNING AND THEN AGAIN
FOR WEDNESDAY NIGHT/THURSDAY MORNING...AS OPPOSED TO THE WIDESPREAD
STRATUS OF THE PREVIOUS FEW NIGHTS.

WEST TO WEST-NORTHWEST FLOW WILL CONTINUE AT 500 MB THROUGH
WEDNESDAY...WITH ONSHORE FLOW AT THE SURFACE AND SEASONAL
TEMPERATURES CONTINUING. A LOW PRESSURE SYSTEM...CURRENTLY OVER THE
NORTHEAST PACIFIC ACCORDING TO WATER VAPOR SATELLITE IMAGERY...WILL
MOVE INTO THE PACIFIC NORTHWEST WEDNESDAY INTO EARLY THURSDAY...WITH
A SECOND WEAKER TROUGH MOVING SOUTH OF SOUTHERN CALIFORNIA. MODELS
CONTINUE TO BE IN GOOD AGREEMENT WITH MOST OF THE MOISTURE BEING
LOCATED ABOVE 500 MB FOR OUR AREA...AND THUS RESULTING IN THICK HIGH
CLOUDS...BUT NO PRECIPITATION...AS THE LOWER LAYERS WILL BE LACKING
IN MOISTURE. HOWEVER...DUE TO THE THICK UPPER LEVEL CLOUDS...THERE
COULD BE A FEW SPRINKLES HERE AND THERE. A LARGER IMPACT WILL LIKELY
BE THE INCREASE IN WESTERLY WINDS AS THE AFOREMENTIONED LOW PRESSURE
SYSTEM MOVES BY FAR TO THE NORTH. GFS AND ECMWF ONLY SHOWING 850 MB
WINDS OF 25-35 KNOTS...AND THE 500 MB JET STAYS FAR TO THE
NORTH...SO WINDS LOOK TO BE AROUND ADVISORY LEVEL. WESTERLY WIND
GUSTS OVER THE RIDGE-TOPS...DESERT SLOPES AND ADJACENT DESERT AREAS
STILL LOOK TO BE IN THE 40-50 MPH RANGE...WHICH AGREES WELL WITH
WHAT THE 00Z AND 12Z CANSAC-WRF SHOW FOR WIND GUSTS FOR THAT TIME.
HOWEVER...LOCAL GUSTS TO 60 MPH MAY OCCUR IN FAVORED LOCATIONS LIKE
BURNS CANYON AND WHITEWATER. STRONGEST WINDS SHOULD OCCUR WEDNESDAY
EVENING/EARLY THURSDAY MORNING AND GRADUALLY DIMINISH THEREAFTER.

LATE THURSDAY...NORTH-NORTHWEST FLOW WILL DOMINATE IN THE UPPER
LEVELS AS THE LOW MOVES INTO THE GREAT BASIN...AND STRATUS WILL MOVE
INTO THE INLAND EMPIRE THURSDAY NIGHT/FRIDAY MORNING. BY LATE FRIDAY
NIGHT...SURFACE HIGH PRESSURE WILL BUILD OVER THE GREAT
BASIN...RESULTING IN WEAK TO MODERATE OFFSHORE FLOW LATE FRIDAY
NIGHT/EARLY SATURDAY MORNING WHICH SHOULD HELP TO SCOUR OUT THE
MARINE LAYER FOR THE MOST PART...ALTHOUGH LOCATIONS ALONG THE COAST
IN SAN DIEGO COUNTY MAY EXPERIENCE PATCHY FOG. WEAK OFFSHORE FLOW
SHOULD PREVAIL SATURDAY...AND MAYBE THROUGH SUNDAY TOO...ALTHOUGH
THE ECMWF SHOWS ONSHORE FLOW RETURNING LATE SUNDAY THEN TURNING
OFFSHORE AGAIN EARLY MONDAY. THE OFFSHORE FLOW SHOULD BRING SLIGHT
WARMING THIS WEEKEND AND LESS CHANCES OF NIGHT AND MORNING MARINE
LAYER STRATUS.

WEATHER WILL REMAIN FAIRLY BENIGN EARLY NEXT WEEK WITH WEAK RIDGING
MOVING IN ALOFT.

&&

.AVIATION...
192030Z...COASTS/VALLEYS...MID AND HIGH LEVEL CLOUDS CONTINUE TO
STREAM IN ACROSS SOUTHERN CALIFORNIA...MAINLY AOA 15000 FT MSL.
THESE CLOUDS WILL THICKEN AND BECOME SCT/BKN OVER THE NEXT 24 HOURS.
AFTER 20/0300Z THIS EVENING...LOW STRATUS CLOUDS WILL RETURN TO THE
COASTAL AIRPORTS WITH BASES BETWEEN 1000-1500 FT MSL AND TOPS TO
AROUND 1800 FT MSL. SIMILAR TO THIS MORNING...LOW CLOUD COVER MAY BE
PATCHY DUE TO THE HIGHER CLOUDS ABOVE THEM.

MTNS/DESERTS...SCT CLOUDS AOA 15000 FT MSL AND UNRESTRICTED VIS
THROUGH WED AFTERNOON. SURFACE WINDS IN THE COACHELLA VALLEY MAY
GUST UP TO 20 KTS OUT OF THE NW LATE THIS AFTERNOON THOUGH EARLY
