AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO
300 AM PST SUN FEB 22 2004

.SYNOPSIS...A BROAD AREA OF LOW PRESSURE WILL CONTINUE...SO SHOWERS
WILL BE WIDESPREAD INTO TONIGHT AND THEN BECOME LESS NUMEROUS
THROUGH MONDAY NIGHT. AN ISOLATED THUNDERSTORM COULD OCCUR THROUGH
TONIGHT...AND HEAVY SNOW WILL BE POSSIBLE IN THE MOUNTAINS. A STRONG
STORM IS EXPECTED WEDNESDAY AND THURSDAY WITH SIGNIFICANT
PRECIPITATION AND STRONG WINDS PLUS HIGH SURF AT THE COAST.

&&

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

THE CENTER OF THE MAIN SURFACE LOW IS NOW ONLY ABOUT 150 MILES W OF
SAN DIEGO AND MOVING ENE. RIGHT NOW...THE SURFACE WINDS ARE MOSTLY
FROM THE SE...AND THAT SEMI-OFFSHORE FLOW IS LIMITING PRECIP A BIT
IN COASTAL AREAS TO MOSTLY LIGHT AMOUNTS...THOUGH OROGRAPHICS IS
PRODUCING SOME RAINFALL GREATER THAN 1/4 INCH/HOUR ON THE SOUTH
SLOPES OF THE SAN GABRIEL/SAN BERNARDINO MTNS. RAIN WAS INCREASING
OFF THE COAST...SO WE SHOULD SEE THE HEAVIER RAIN RATES ON LAND IN
THE NEXT FEW HOURS. ALSO...ONCE THE LOW REACHES LAND AROUND
MIDDAY...THE FLOW WILL BE MORE S/SW...SO THAT WILL BRING A BETTER
TRAJECTORY FOR HEAVY RAIN...AND HEAVY SNOW IN THE MTNS. THE RH WILL
BE HIGHEST ALOFT AT THAT TIME TOO. OVERALL...RAINFALL SHOULD AROUND
ONE INCH NEAR THE COAST WITH LOCAL SPOTS OF 3+ INCHES ON THE SOUTH
SLOPES OF THE SAN GABRIELS THROUGH ABOUT MONDAY.

WE DO GO OFFSHORE AT THE SURFACE EARLY TUE AS WEAK RIDGING
OCCURS...SO WE SHOULD SEE A BRIEF END TO THE PRECIP. HOWEVER...A
SYSTEM WHICH WILL PROBABLY BE STRONGER THAN THE ONE FOR THIS WEEKEND
WILL AFFECT THE AREA WED/THU. ONSHORE FLOW WILL BE STRONG SINCE THE
STROM WILL BE CENTERED FURTHER NORTH THAN THE CURRENT STORM...SO
OROGRAPHIC PRECIP COULD BE MAJOR. THE ENSEMBLES SHOW A RATHER HIGH
CONFIDENCE FOR THIS AS THERE IS SURPRISINGLY LOW VARIABILITY IN THE
DEPTH OF THE LONGWAVE TROUGH WITH JUST MINOR VARIABILITY IN THE
TIMING. SOMETIME AROUND FRI/SAT...THE TROUGH SHOULD MOST
EAST...THOUGH WE WILL STILL BE OPEN TO MORE TROUGHS MOVING IN FROM
THE WEST FOR MORE PRECIP DUE TO AN ACTIVE PAC JET STREAM.
