AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
448 AM PDT MON MAR 21 2011

...WET AND STORMY WEEK AHEAD...

.DISCUSSION...AS OF 3:50 AM PDT SUNDAY...A COLD UPPER TROUGH IS
CENTERED OVER THE CENTRAL CALIFORNIA COAST EARLY THIS MORNING AND IT
CONTINUES TO SPAWN SCATTERED SHOWERS ACROSS THE REGION...MAINLY
SOUTHERN AREAS. MODELS INDICATE THAT SHOWER ACTIVITY WILL INCREASE
IN THE AFTERNOON AS SURFACE HEATING PRODUCES GREATER INSTABILITY.
ISOLATED THUNDERSTORMS ARE ALSO POSSIBLE THIS AFTERNOON.

THE UPPER TROUGH WILL MOVE INLAND THIS EVENING AND SHOWERS SHOULD
TAPER OFF AND MOSTLY END OVERNIGHT. TUESDAY SHOULD START OFF DRY FOR
THE MOST PART WITH PERHAPS ISOLATED SHOWERS IN THE MORNING. CLOUDS
WILL THEN INCREASE IN THE AFTERNOON AS THE NEXT SYSTEM APPROACHES
FROM THE WNW. RAIN WILL LIKELY BEGIN NEAR THE COAST BY LATE TUESDAY
AFTERNOON AND THEN SPREAD ACROSS THE AREA ON TUESDAY EVENING. THE
MODELS AGREE THAT THIS SYSTEM WILL PRODUCE MODERATE AMOUNTS OF WIND
AND RAIN LATE TUESDAY AND TUESDAY NIGHT. SOUTHERLY WINDS WILL
INCREASE TUESDAY AFTERNOON AND EVENING WITH GUSTS TO 40 MPH POSSIBLE.
NUMEROUS SHOWERS WILL CONTINUE THROUGH WEDNESDAY AND THUNDERSTORMS
MAY ALSO OCCUR THAT DAY. RAINFALL TOTALS FROM LATE TUESDAY THROUGH
WEDNESDAY ARE EXPECTED TO RANGE FROM 0.50 TO 1.0 INCH AT LOWER
ELEVATIONS AND FROM 0.75 TO 2 INCHES IN THE HILLS. SOME OF THE WETTER
LOCATIONS IN THE COASTAL RANGES MAY PICK UP AS MUCH AS 3 INCHES OF
RAIN BY LATE WEDNESDAY.

ANOTHER SYSTEM WILL BE CLOSE ON THE HEELS OF THE TUESDAY
NIGHT/WEDNESDAY SYSTEM...BRINGING MORE RAIN AND WIND TO THE FORECAST
AREA ON THURSDAY. THE THURSDAY SYSTEM SHOULD BE AT LEAST AS WINDY AS
TUESDAY NIGHT'S...AND ALSO CAPABLE OF PRODUCING MORE INTENSE
RAINFALL. RAIN RATES ON THURSDAY COULD BE HEAVY AT TIMES. THE SOIL
IS ALREADY SATURATED AND RIVERS AND STREAMS ARE PRIMED FOR RAPID
RISES. SIGNIFICANT HYDRO ISSUES ARE NOT LIKELY THROUGH WEDNESDAY...
ALTHOUGH MINOR NUISANCE FLOODING COULD OCCUR. BY THURSDAY...FLOODING
COULD BECOME MORE OF AN ISSUE DUE TO A COMBINATION OF SATURATED
SOILS...SEVERAL CONSECUTIVE RAINY DAYS...AND INCREASED RAINFALL
INTENSITY.

THE MEDIUM RANGE MODELS INDICATE THAT YET ANOTHER SYSTEM WILL MOVE
IN OVER THE UPCOMING WEEKEND. THE UPSHOT IS THAT THE FIRST FULL WEEK
OF SPRING WILL BE WET AND STORMY.

&&

.AVIATION...AS OF 4:40 AM MONDAY MORNING...SCATTERED SHOWERS AND
POSSIBLE THUNDERSTORMS WILL IMPACT THE TERMINALS TODAY. THE
CONCENTRATION OF SHOWERS OVERNIGHT HAS BEEN SOUTH OF SAN FRANCISCO
BAY...HOWEVER THIS ACTIVITY IS EXPECTED TO SHIFT NORTHWARD THROUGH
THE DAY.  MAINLY VFR CIGS...WITH OCCASIONAL MVFR POSSIBLE WITH SOME
OF THE HEAVIER SHOWERS.  THERE IS A LOT OF UNCERTAINTY WITH
THE LOCATION AND TIMING OF SHOWERS...SO LOWER CIGS WERE NOT INCLUDED
IN THE TAFS.  OTHERWISE...LIGHT TO MODERATE OFFSHORE WINDS WILL
TURN ONSHORE THIS AFTERNOON.  SUSTAINED SPEEDS AROUND 12 KNOTS WITH
GUSTS TO 20 KNOTS NOT OUT OF THE QUESTION DURING THE AFTERNOON
HOURS.

VICINITY OF KSFO...SCATTERED SHOWERS WILL IMPACT KSFO AND KOAK
THROUGH THE FORECAST.  THE FORECAST WILL NEED TO BE MONITORED
CLOSELY TODAY...AS THERE IS A SLIGHT CHANCE OF THUNDERSTORMS LATER
THIS AFTERNOON.  CONFIDENCE IS LOW SO NO MENTION IN THE FORECAST.
OTHERWISE...WESTERLY WINDS INCREASE AFTER 21Z THIS AFTERNOON...WITH
GUSTS TO 20 KNOTS POSSIBLE THROUGH 04Z TUESDAY.

KSFO BRIDGE APPROACH...SIMILAR TO KSFO.

MONTEREY BAY AREA TERMINALS...NUMEROUS SHOWERS WILL BE POSSIBLE OVER
THE NEXT FEW HOURS AT BOTH KMRY AND KSNS.  REDUCED VISIBILITIES AND
CIGS DOWN TO 2000 FEET WILL BE POSSIBLE WITH THE HEAVIEST OF
SHOWERS.  OTHERWISE...SCATTERED SHOWERS WILL REMAIN IN THE AREA
THROUGH THE FORECAST.  MODERATE ONSHORE FLOW AFTER 18Z...WITH GUSTS
TO 15 KNOTS POSSIBLE AT BOTH TERMINALS.  WINDS WILL BEGIN TO
SUBSIDE AROUND 02Z TUESDAY...AND REMAIN LIGHT THROUGH THE FORECAST.
