AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
1131 PM PDT FRI MAR 16 2012

.DISCUSSION...AS OF 9:10 PM PDT FRIDAY...WIDESPREAD RAIN IS
OCCURRING THROUGHOUT OUR REGION THIS EVENING AS A COLD FRONT
ADVANCES FROM THE NORTHWEST INTO A MOIST AIRMASS. RAIN RATES HAVE
BEEN MODERATE IN MOST AREAS...BUT AREAS OF HEAVY RAIN HAVE BEEN
OCCURRING IN THE SANTA CRUZ MOUNTAINS...AND LOCALLY ELSEWHERE
ACROSS THE SAN FRANCISCO BAY AREA. RAIN RATES IN EXCESS OF A HALF
INCH PER HOUR HAVE BEEN REPORTED IN THE SANTA CRUZ MOUNTAINS.
THERE HAVE BEEN SEVERAL REPORTS OF MINOR STREET FLOODING. AN
URBAN AND SMALL STREAM FLOOD ADVISORY HAS BEEN ISSUED FOR MUCH OF
THE CENTRAL AND SOUTHERN SAN FRANCISCO BAY AREA...SOUTH INTO
MONTEREY AND SAN BENITO COUNTIES. THE ADVISORY IS IN EFFECT UNTIL
10:45 PM PDT. ISOLATED CONVECTION IS EMBEDDED IN THE BROAD AREA OF
RAINFALL. A LIGHTING STRIKE WAS DETECTED IN SW CONTRA COSTA COUNTY
AT ABOUT 5 PM THIS AFTERNOON AND THUNDER WAS HEARD IN HOLLISTER AT
ABOUT 7:30 PM.

BASED ON RADAR AND SURFACE REPORTS...IT APPEARS THAT THE SURFACE
COLD FRONT IS CURRENTLY MOVING THROUGH THE NORTH BAY AND RAINFALL
IS TAPERING OFF QUICKLY BEHIND THE FRONT. EXTRAPOLATING THE
CURRENT FRONTAL SPEED AND CONSIDERING THE 00Z NAM'S TIMING...WOULD
EXPECT THE FRONT TO MOVE THROUGH MOST OF THE SF BAY AREA BY
MIDNIGHT AND THROUGH THE MONTEREY BAY AREA BY 2 AM. SATELLITE
SHOWS CLEARING BEHIND THE FRONT AND MODEL OUTPUT INDICATES A
PERIOD OF DRY WEATHER AFTER FRONTAL PASSAGE LATE TONIGHT INTO
EARLY SATURDAY MORNING. SHOWERS WILL THEN DEVELOP BY MID TO LATE
SATURDAY MORNING AS A SHORTWAVE ROTATING THROUGH THE BASE OF THE
LONGWAVE TROUGH APPROACHES THE CENTRAL CA COAST. THE GFS AND NAM
AGREE THAT THE TRACK OF THIS SHORTWAVE WILL BE FAR ENOUGH SOUTH TO
PLACE NEARLY ALL OF SATURDAY'S SHOWER ACTIVITY OVER THE SOUTHERN
HALF OF OUR FORECAST AREA. THE 12Z ECMWF...ON THE OTHER
HAND...TRACKS THE SHORTWAVE INLAND FARTHER TO THE NORTH AND
THEREFORE FOCUSES THE SHOWER ACTIVITY OVER THE HEART OF THE SF BAY
AREA. GIVEN THE UNCERTAINTY...WILL CONTINUE TO FORECAST AT LEAST A
CHANCE OF SHOWERS IN ALL AREAS...WITH HIGHER POPS ACROSS THE
SOUTH. ISOLATED THUNDERSTORMS WILL CONTINUE TO BE POSSIBLE ON
SATURDAY AS A COLD AND UNSTABLE AIRMASS SPILLS ACROSS THE AREA.
SHOWER CHANCES WILL CONTINUE ALL THE WAY THROUGH THE
WEEKEND AS THE COLD UPPER TROUGH MOVES VERY SLOWLY TO THE EAST.
BUT SHOWER CHANCES WILL DIMINISH BY SUNDAY AS THE AIRMASS BECOMES
DRIER AND A LITTLE MORE STABLE.

SNOW LEVELS ARE FORECAST TO DROP TO 2500 FEET ON SATURDAY AND THEN
AS LOW AS 2000 FEET ON SATURDAY NIGHT AND SUNDAY. IF THE NAM AND
GFS ARE CORRECT...THERE WILL BE LITTLE CHANCE OF SNOW IN THE HILLS
OF THE SAN FRANCISCO BAY AREA (ASIDE FROM THE SOUTHERN DIABLO
RANGE) SINCE LITTLE OR NO PRECIP IS FORECAST. SNOW IS MORE LIKELY
SOUTH...IN THE MOUNTAINS OF MONTEREY AND SAN BENITO COUNTIES.
ACCUMULATION IS LIKELY ABOVE 2000 FEET AND THERE COULD BE UP TO 6
INCHES OF ACCUMULATION OVER THE WEEKEND IN THE SANTA LUCIAS ABOVE
2500 FEET.

AN UPPER RIDGE IS FORECAST TO BUILD JUST OFFSHORE EARLY IN THE
WORK WEEK AND THERE COULD BE SOME LIGHT WARM ADVECTION RAIN ON
MONDAY INTO MONDAY NIGHT AS MOISTURE SPILLS OVER THE TOP OF THE
RIDGE. GENERALLY DRY AND MILD CONDITIONS ARE EXPECTED FOR THE REST
OF THE WEEK EXCEPT PERHAPS SOME RAIN OVER THE NORTH BAY AROUND
MIDWEEK AS A FAST-MOVING SYSTEM MOVES INLAND TO THE NORTH. MORE
SUBSTANTIAL AND WIDESPREAD RAINFALL IS POSSIBLE ONCE AGAIN BY NEXT
WEEKEND.

&&

.AVIATION...AS OF 11:15 PM PDT FRIDAY...A PACIFIC FRONTAL SYSTEM
IS MOVING SOUTHEASTWARD THROUGH THE MONTEREY BAY REGION AND WILL
EXIT THE DISTRICT LATER TONIGHT. CEILINGS AND VISIBILITIES ARE IMPROVING
BEHIND IT...WITH VFR CONDITIONS NOW PREVAILING AT THE SFO BAY AREA
TERMINALS AND EXPECTED TO SIMILARLY DEVELOP AT KMRY AND KSNS
SOON AFTER MIDNIGHT. SOME FOG WILL LIKELY DEVELOP LATE TONIGHT IN
THE NORTH SFO BAY VALLEYS AND LEAD TO IFR OR EVEN LIFR CONDS AT
KSTS INTO THE FIRST PART OF SATURDAY MORNING. A COOL...MOIST AND
UNSTABLE AIR MASS WILL RESULT IN CONTINUING SCATTERED
SHOWERS...AND THE POSSIBILITY OF A FEW ISOLATED THUNDERSTORMS AND
ALSO SOME SMALL HAIL. CEILINGS AND VISIBILITIES SHOULD GENERALLY
REMAIN VFR HOWEVER...ALTHOUGH CAN'T RULE OUT POSSIBLE TEMPORARY
DEVELOPMENT OF MORE RESTRICTED CONDITIONS IN A HEAVIER SHOWER.
WINDS HAVE RAPIDLY DIMINISHED FOLLOWING FRONTAL PASSAGE...AND WILL
GENERALLY REMAIN LIGHT OVERNIGHT AND SATURDAY MORNING.
HOWEVER...MODERATE TO LOCALLY STRONG AND GUSTY ONSHORE WINDS ARE
EXPECTED TO DEVELOP DURING THE AFTERNOON ON SATURDAY.

VICINITY OF KSFO...VFR CEILINGS AND VISIBILITIES EXPECTED TO
PREVAIL OVERNIGHT AND ON SATURDAY...THOUGH WITH POSSIBLE TEMPORARY
DEVELOPMENT OF MORE RESTRICTED CONDITIONS DURING PASSAGE OF A
HEAVIER SHOWER. WINDS WILL REMAIN LIGHT OUT OF THE NORTHWEST
THROUGH SATURDAY MORNING...AND THEN INCREASE OUT OF THE WEST
DURING THE AFTERNOON. THERE IS A SLIGHT CHANCE OF A FEW
THUNDERSTORMS ALONG WITH SMALL HAIL LATE TONIGHT AND ON SATURDAY.

KSFO BRIDGE APPROACH...SIMILAR TO KSFO.

MONTEREY BAY AREA TERMINALS...CIGS AND VSBYS EXPECTED TO BECOME
VFR BY AROUND 08Z AND THEN REMAIN VFR THROUGH SATURDAY...THOUGH
WITH POSSIBLE TEMPORARY DEVELOPMENT OF MORE RESTRICTED CONDITIONS
DURING PASSAGE OF A HEAVIER SHOWER. THERE IS A SLIGHT CHANCE OF A FEW
THUNDERSTORMS ALONG WITH SMALL HAIL LATE TONIGHT AND ON SATURDAY.

&&

.MARINE...AS OF 10:45 PM PDT FRIDAY...A STEEP FRESH SWELL WILL BE
GENERATED FROM A STORM SYSTEM MOVING TOWARDS THE REGION FROM THE
GULF OF ALASKA. THE LARGEST SWELLS WILL REMAIN OVER THE OUTER
WATERS...BUT WITH LARGE SNEAKER WAVES AND RIP CURRENTS POSSIBLE ALONG
THE COAST. THE LARGEST SWELLS WILL DEVELOP OVER THE WATERS
SATURDAY NIGHT...CONTINUING THROUGH SUNDAY. SWELLS WILL BEGIN TO SLOWLY
SUBSIDE EARLY NEXT WEEK. MARINERS AND BEACH GOERS ARE URGED TO
CONTINUE TO MONITOR THE FORECAST THROUGH THE WEEKEND.
