AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
855 PM PDT TUE MAY 31 2011

...COOL AND UNSETTLED WEATHER FORECAST THROUGH THE WEEK AND INTO
NEXT WEEKEND...

.DISCUSSION...AS OF 8:55 PM PDT TUESDAY...SHOWER ACTIVITY HAS
DIMINISHED SUBSTANTIALLY THIS EVENING WITH ONLY A COUPLE RETURNS
NOTED OFF THE CENTRAL CALIFORNIA COAST AT THIS HOUR. THE UNSEASONABLY
COOL LOW RESPONSIBLE FOR TODAY'S WEATHER CONTINUES TO SPIN OFF THE
NORTHERN CALIFORNIA COAST AND IS SHOWING ONLY SLIGHT MOVEMENT
EASTWARD. THIS SYSTEM SPARKED THUNDERSTORMS NORTH OF OUR AREA NEAR
REDDING EARLIER THIS AFTERNOON AND EVENING AS WELL AS A FUNNEL CLOUD
OVER THE BAY AREA. THE FUNNEL CLOUD WAS OBSERVED OVER THE SAN
FRANCISCO BAY...SOUTHWEST OF EMERYVILLE BY A SPOTTER EARLIER THIS
AFTERNOON.

UNSTABLE CONDITIONS WILL CONTINUE THROUGH WEDNESDAY AS THIS LOW MOVES
INLAND AND ACROSS NORTHERN CALIFORNIA. SHOWER ARE EXPECTED TO
ACCOMPANY THE LOW AS IT MOVES ACROSS THE REGION. SHOWERS ARE EXPECTED
OVER THE NORTH BAY TO AS FAR SOUTH AS THE MONTEREY BAY WITH ISOLATED
THUNDERSTORMS POSSIBLE MAINLY NORTH OF SAN FRANCISCO IN THE
AFTERNOON. COLD AIR ASSOCIATED WITH THIS SYSTEM WILL ALSO MOVE INLAND
ON WEDNESDAY CAUSING ALREADY COOL TEMPERATURES TO DROP A COUPLE OF
DEGREES. MOST LOCATION REPORTED HIGHS IN THE UPPER 50S AND 60S WITH A
FEW SCATTERED 70S HERE AND THERE THIS AFTERNOON. AS NOTED IN THE
PREVIOUS DISCUSSION THESE TEMPERATURES ARE RUNNING 5 AND 10 DEGREES
BELOW NORMAL FOR THE LAST DAY OF MAY. THERE IS NO SIGNIFICANT WARMING
EXPECTED IN THE NEAR FUTURE AS WE ANTICIPATED YET ANOTHER STORM TO
AFFECT THE REGION ON FRIDAY AND INTO THE WEEKEND.

FROM PREVIOUS DISCUSSION...
A RETURN TO AN ACTIVE WEATHER PATTERN WILL OCCUR ON FRIDAY...AS A
STORM SYSTEM IN THE GULF OF ALASKA MOVES QUICKLY SOUTH TOWARDS THE
CENTRAL CALIFORNIA COAST.  THIS STORM SYSTEM HAS THE POSSIBILITY OF
BRINGING SIGNIFICANT RAIN TO THE REGION OVER THE WEEKEND.  THE NAM...
GFS...AND ECMWF ARE IN AGREEMENT THAT PRECIPITATION WILL ENTER THE
NORTH BAY BY FRIDAY AFTERNOON AND SHIFT SOUTH THROUGH THE EVENING
HOURS.  BY SATURDAY MORNING...THE GFS AND ECMWF ARE IN AMAZING
AGREEMENT WITH REGARDS TO THE POSITION OF THE UPPER LOW.  THE UPPER
LOW WILL BE JUST WEST OF THE SAN FRANCISCO BAY...ALLOWING FOR THE
GREATEST CHANCE OF MODERATE TO HEAVY RAIN THROUGHOUT THE REGION.
WIDESPREAD ACCUMULATION BETWEEN A QUARTER AND A HALF INCH WILL BE
POSSIBLE...WITH ISOLATED LOCATIONS RECEIVING OVER AN INCH OF RAIN
THROUGH THE WEEKEND.  CONFIDENCE CONTINUES TO GROW WITH THE WEATHER
SCENARIO THIS WEEKEND...AND WE WILL MONITOR THIS SITUATION CLOSELY
INTO THE WEEKEND.

BY MONDAY...THE UPPER LOW WILL BEGIN TO MOVE SLOWLY EAST...ALLOWING
A BREAK IN THE WET WEATHER AND COOL TEMPERATURES.  BY TUESDAY...THE
FORECAST IS DRY...AND DAYTIME HIGH TEMPERATURES WILL BE NEAR
NORMAL.

&&

.AVIATION...AS OF 10:30 PM PDT TUESDAY...LOW LEVEL MOISTURE
WILL ALLOW MVFR CIGS TO DEVELOP AFTER 06Z. CIGS WILL RISE AFTER
16-18Z BECOMING SCT-BKN CUMULUS CLOUDS. UPPER TROUGH MOVES THROUGH
WEDNESDAY BRINGING SCATTERED SHOWERS TO THE NORTH BAY AND SFO BAY
AREA.

VICINITY OF KSFO...MVFR CIGS FORMING OVERNIGHT. CIGS BREAKING UP
AFTER 16Z BECOMING SCT-BKN CU AT AROUND 3000 FEET WITH SCATTERED
SHOWERS POSSIBLE. LIGHT SOUTH TO SOUTHEAST WINDS OVERNIGHT AND
WEDNESDAY BECOMING SOUTHWEST LATE IN THE AFTERNOON.

KSFO BRIDGE APPROACH...SIMILAR TO KSFO.

MONTEREY BAY AREA TERMINALS...MVFR CIGS WILL BE INCREASING
TONIGHT. CLEARING TO SCT-BKN CU AFTER 16Z.
