AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
530 AM PST WED JAN 20 2010

.SYNOPSIS...
ANOTHER PAIR OF PACIFIC STORMS WILL BRING PERIODS OF STRONG GUSTY
WINDS...HEAVY PRECIPITATION...AND HIGH SURF THROUGH FRIDAY. DRY AND
WARMER FOR LATE SATURDAY THROUGH MONDAY UNDER HIGH PRESSURE.

&&

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

.SHORT TERM (TODAY THROUGH FRIDAY)...
THE SECOND IN THE SERIES OF PACIFIC STORMS MOVED THROUGH ON TUESDAY.
RAINFALL WAS LESS THAN ON MONDAY...MOSTLY ONE HALF TO ONE INCH WITH
LOCALLY GREATER AMOUNTS. IT WAS MORE CONVECTIVE AS EXPECTED. SNOW
LEVELS BEHIND IT LOWERED TO 4500 TO 5000 FEET...A LITTLE LOWER THAN
EXPECTED...BUT ARE EXPECTED TO RISE TO AROUND 6000 FEET LATER THIS
MORNING. AS WITH THE MONDAY STORM...THERE WAS A STRONG PREFRONTAL
LOW LEVEL JET. GENERAL GUSTS WERE A LITTLE LESS THAN FOR
MONDAY...BUT PEAK GUSTS WERE STRONGER...POSSIBLY FROM THE CONVECTIVE
CELLS. THERE WERE SOME ISLAND BAND SHOWERS FOLLOWING THE FRONTAL
PASSAGE THAT CONTINUED PAST MIDNIGHT.

AS FOR THIS MORNING...NUMEROUS LIGHT TO LOCALLY MODERATE SHOWERS ARE
DEVELOPING IN THE WARM ADVECTION ZONE AHEAD OF THE NEXT STORM FOR
LATER TODAY. COVERAGE OF THESE SHOWERS IS GREATEST FROM SANTA
BARBARA COUNTY EASTWARD TO ORANGE COUNTY AND WESTERN PORTIONS OF THE
INLAND EMPIRE. SOME OF THE SHOWERS MAY EVENTUALLY EXTEND SOUTHWARD
INTO SAN DIEGO COUNTY DURING THE MORNING.

THE NEXT STORM IS EXPECTED TO ARRIVE THIS AFTERNOON WITH RAINFALL
TOTALS SIMILAR TO THOSE OF MONDAY...1 TO 2 INCHES NEAR THE COAST TO
2 TO 4 INCHES ON THE COASTAL MOUNTAIN SLOPES. SOUTH WINDS AHEAD OF
AND NEAR THE FRONT WILL BE SIMILAR TO THOSE OF THE PAST TWO DAYS.
MID LEVEL TEMPERATURES WILL WARM A FEW DEGREES DECREASING THE
INSTABILITY SOMEWHAT. THERE WILL STILL BE A CHANCE OF THUNDERSTORMS
WITH THIS FRONTAL PASSAGE BUT WITH CHANCES A LITTLE LESS THAN THOSE
OF YESTERDAY. THE LOW LEVEL VERTICAL SHEAR PROFILE NEAR THE FRONT
WILL ONCE AGAIN BE CONDUCIVE FOR ISOLATED WATERSPOUTS AND TORNADOES.

A LOW LEVEL WARM ADVECTION PATTERN WILL BECOME QUICKLY REESTABLISHED
TONIGHT INTO THURSDAY FOLLOWING THE PASSAGE OF THE STORM LATER
TODAY. THIS SHOULD KEEP THE SHOWERS GOING...ESPECIALLY IN THE
NORTHERN AREAS TONIGHT INTO EARLY THURSDAY WITH ADDITIONAL RAINFALL
TOTALS ON SOUTHWEST FACING SLOPES OF THE SAN GABRIEL AND SAN
BERNARDINO MOUNTAINS OF 1 TO 2 INCHES.

THE FOURTH AND STRONGEST IN THIS SERIES OF STORMS IS EXPECTED TO
MOVE THROUGH ON THURSDAY. FOLLOWING THE PREFERRED ECMWF
SOLUTION...IT IS POSSIBLE THAT LINDBERGH FIELD COULD SET A NEW
RECORD FOR THE LOWEST RECORDED SURFACE PRESSURE ON THURSDAY. ANOTHER
ROUND OF HEAVY RAINFALL IS EXPECTED ON THURSDAY...FOLLOWED BY
SHOWERS AND SCATTERED THUNDERSTORMS THURSDAY AFTERNOON AND EVENING
WITH THE ARRIVAL OF MUCH COLDER AIR ALOFT. SMALL HAIL OR GRAUPEL
WILL BE POSSIBLE WITH SOME OF THESE THUNDERSTORMS AND HEAVIER
SHOWERS FOR LATE THURSDAY INTO FRIDAY. THE PATTERN FOR THURSDAY WILL
ONCE AGAIN BE FAVORABLE FOR THE DEVELOPMENT OF ISOLATED WATERSPOUTS
AND TORNADOES WITH THE UPPER SYNOPTIC PATTERN CLOSEST TO THE
CLIMATOLOGICALLY MOST FAVORABLE PATTERN OF ANY DAY THIS WEEK.

THE ADDITIONAL HEAVY RAINFALL ON THURSDAY COUPLED WITH THE HIGH
INTENSITY RAINFALL FROM THUNDERSTORMS AND HEAVIER SHOWERS WILL BRING
THE HIGHEST POSSIBILTY OF FLASH FLOODING DURING THE WEEK FOR
THURSDAY INTO THURSDAY NIGHT.

SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE FRIDAY...
DECREASING FRIDAY NIGHT.

&&

.LONG TERM (SATURDAY THROUGH TUESDAY)...
SHOWERS ARE EXPECTED TO END EARLY SATURDAY WITH HIGH PRESSURE
BRINGING DRY AND WARMER WEATHER FOR LATE SATURDAY THROUGH MONDAY.
ANOTHER PACIFIC STORM...FASTER MOVING AND WEAKER THAN THOSE OF THIS
WEEK...IS POSSIBLE AROUND TUESDAY OF NEXT WEEK.

&&

.AVIATION...
201100Z...POST FRONTAL ISOLATED SHOWERS WILL CONTINUE THIS EARLY
MORNING AS ANOTHER THICK SHIELD OF 5000 FT ALTOSTRATUS BEGINS TO
SPREAD IN FROM THE WEST AHEAD OF THE NEXT MAJOR STORM. HEAVY RAIN
AND 1500 TO 2500 FT CEILINGS WILL MOVE IN FROM THE WEST STARTING
AROUND 18Z WITH PERIODS OF HEAVY RAIN...LOCAL GUSTY 50 MPH SOUTH
WINDS... THUNDERSTORMS...AND MOUNTAIN SNOW CONTINUING THROUGH
TONIGHT. AN AIRPORT WEATHER WARNING MAY BE NEEDED FOR KSAN THIS
AFTERNOON.

&&

.MARINE...
201100Z...FRONTS ACCOMPANIED BY GALE FORCE WINDS WILL CREATE A LARGE
WIND WAVE ON TOP OF THE LONGER PERIOD SWELL...CREATING COMBINED SEAS
IN THE 20 TO 25 FT RANGE. A SMALL CRAFT ADVISORY IS IN EFFECT FOR
THE REMAINDER OF THE WEEK AND A GALE WATCH HAS BEEN ISSUED BEGINNING
AT 10 AM TODAY AND CONTINUING THROUGH TONIGHT.

A RARE STORM SURGE IS EXPECTED TO RAISE THE RISK OF COASTAL FLOODING
LATE THIS MORNING THROUGH SATURDAY. THIS EVENT WILL LIKELY CAUSE
EXTENSIVE BEACH EROSION AND LOCAL OVERFLOW INTO LOW LYING AREAS SUCH
AS HUNTINGTON BEACH...SEAL BEACH...SUNSET BEACH...LA JOLLA...DEL
MAR...AND CARDIFF. IT MAY ALSO CAUSE DAMAGE TO PIERS...JETTIES...AND
SEA WALLS. THE SURF WILL BE HIGH TODAY THROUGH THE WEEKEND...BUT
PARTICULARLY HIGH FRIDAY AND SATURDAY SOUTH OF OCEANSIDE...WHERE
BREAKERS AS HIGH AS 25 FEET ARE POSSIBLE ON THE OUTSIDE REEFS.
