AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
1038 AM PDT SUN MAR 13 2011

.DISCUSSION...AS OF 9:00 AM PDT SUNDAY...ECHOS ON THE COASTAL RADARS
HAVE CONTINUED TO INCREASE THIS MORNING AS A 970 MB SURFACE LOW
NEAR 45N/140W CONTINUES TO TRACK TOWARD THE BC COAST. ALL
INDICATIONS ARE THE BULK OF THE RAIN AND BEST DYNAMICS WILL STAY TO
THE NORTH AS THE SYSTEM LIFTS TO THE NE...SO DO NOT ANTICIPATE ANY
MAJOR WEATHER ISSUES OVER THE NEXT 24 HOURS IN OUR CWA. RAIN WILL
SPREAD NORTH TO SOUTH THROUGH THE DAY TODAY (LIGHT RAIN COULD
HAPPEN AS EARLY AS 10 AM AROUND PORTIONS OF SF BAY). MOST OF
THE RAIN WILL END BY LATE TONIGHT AS THE MAIN LOW TRACKS EVEN FURTHER
TO THE NORTH. HIGHEST TOTALS ARE EXPECTED OVER THE NORTH BAY
MOUNTAINS WITH 1" POSSIBLE. URBAN LOCATIONS SHOULD PICK UP LESS THAN
1/2" WITH MANY REPORTS OF CLOSE TO 1/4" EXPECTED. MOST PLACES FROM
SANTA CLARA VALLEY SOUTHWARD (OUTSIDE OF THE SANTA CRUZ MOUNTAINS)
WILL GET LESS THAN 1/4" WITH UNDER 1/10" FORECAST FOR MUCH OF
MONTEREY AND SAN BENITO COUNTIES. IS WORTH NOTING THAT SWELLS UP TO
15 FEET ARE FORECAST WITH PERIODS AROUND 15 SECONDS BY TOMORROW SO
COULD BE LOOKING AT SOME MINOR COASTAL ISSUES. WILL PROBABLY ISSUE A
HIGH SURF ADVISORY FOR MONDAY MORNING AND AFTERNOON WITH THE
NEXT PACKAGE.

THE BREAK IN THE WEATHER WILL BE BRIEF AS A SECOND LOW AGAIN TRACKS
TOWARD THE BC COAST AND BRINGS MORE RAIN TO OUR AREA BY MONDAY
NIGHT. THE MAIN TARGET WILL REMAIN FROM SF BAY NORTHWARD WITH MUCH
HEAVIER AMOUNTS WELL TO THE NORTH OF OUR CWA. THIS COULD EASILY
DROP SIMILAR AMOUNTS AS THE SYSTEM WE WILL SEE TODAY. THEREFORE...
SPOTS SUCH AS VENADO COULD GET A TOTAL OF 2" FROM THESE TWO STORMS.

.PREVIOUS EXTENDED...RELATIVELY MILD AIR WILL ACCOMPANY THE WEATHER
SYSTEMS MOVING ASHORE DURING THE FIRST HALF OF THE WEEK. THUS...
TEMPERATURES WILL ONLY DIP SLIGHTLY BELOW NORMAL IN THE NORTH...AND
PROBABLY REMAIN NEAR NORMAL ACROSS THE SOUTH WHERE LESS CLOUD COVER
WILL ALLOW TEMPERATURES TO WARM TO SEASONABLE LEVELS.

THE MEDIUM RANGE MODELS AGREE THAT A CUTOFF LOW WILL DEVELOP OFF
THE CA/OR BORDER LATE IN THE WEEK. THIS SYSTEM WILL LIKELY PRODUCE
HEAVIER RAINFALL THURSDAY NIGHT AND FRIDAY COMPARED TO THOSE FROM
EARLIER IN THE WEEK...PARTICULARLY ACROSS THE SOUTH. ALSO...THIS
SYSTEM WILL CONTAIN A COLDER AND MORE UNSTABLE AIRMASS. THEREFORE...
THUNDERSTORMS ARE A POSSIBILITY AS THE UPPER LOW APPROACHES THE
COAST LATE FRIDAY...AND ALSO INTO NEXT WEEKEND AS THE LOW MOVES
INLAND. WILL HOLD OFF ON ADDING THUNDERSTORMS TO THE FORECAST FOR
NOW AND WAIT UNTIL TIMING AND LOCATION OF THE UPPER LOW IS MORE
CERTAIN.

&&

.AVIATION...AS OF 10:38 AM PDT SUNDAY...AT THIS TIME MOSTLY MID-HIGH
LEVEL CLOUDS STREAM OVER THE REGION AHEAD OF A COLD FRONT. A
BRIEF LIGHT SHOWER IS POSSIBLE THIS MORNING...BUT MAINLY N BAY WITH
CIGS AOA 3K FT. OTHERWISE...MOSTLY VFR CONDITIONS THROUGH THIS
AFTERNOON. STEADIER PRECIP AND MVFR CIGS WILL GRADUALLY DEVELOP OVER
THE N BAY AFTER 18Z TODAY AND MOVE TOWARD SF BAY AROUND 22-00Z. CONF
IS LOW ON HOW FAR SOUTH PRECIP WILL ACTUALLY OCCUR. CIGS WILL LIKELY
LIFT AND PRECIP WILL GRADUALLY END AFTER 06Z TONIGHT AS THE FRONT
PUSHES THROUGH.

VICINITY OF KSFO...VFR CONDITIONS AND RELATIVELY LIGHT WINDS THIS
MORNING INTO EARLY THIS AFTERNOON. LIGHT PRECIP AND MVFR
CIGS AFTER 20Z. SOUTHERLY FLOW WILL ALSO INCREASE THIS AFTERNOON.

KSFO BRIDGE APPROACH...SAME AS KSFO.

MONTEREY BAY AREA TERMINALS...MOSTLY VFR CONDITIONS THROUGH THE
PERIOD. CONF IS LOW FOR ACTUAL PRECIP AROUND MRY BAY...BUT WILL
HAVE MVFR CIGS TONIGHT.
