AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
832 AM PDT WED SEP 2 2015

.SYNOPSIS...DRY WEATHER WILL CONTINUE THROUGH NEXT WEEK.
TEMPERATURES WILL CONTINUE TO COOL THROUGH SATURDAY AS AN UPPER
LEVEL TROUGH DIGS SOUTHWARD INTO THE PACIFIC NORTHWEST. WARMER AND
DRIER CONDITIONS RETURN OVER THE WEEKEND AND EARLY NEXT WEEK.

&&

.DISCUSSION...AS OF 8:30 AM PDT WEDNESDAY...THANKS TO A MUCH
DEEPER MARINE LAYER (NOW OVER 2000 FEET) PLUS AN ONSHORE FLOW AT
THE SURFACE...CLOUD COVER IS MUCH MORE SUBSTANTIAL TODAY COMPARED
TO RECENT MORNINGS.

CURRENT FORECAST APPEARS TO BE ON TRACK. NO SUBSTANTIAL UPDATES
ANTICIPATED.

.PREVIOUS DISCUSSION...GENERALLY QUIET WEATHER WILL CONTINUE FOR
THE BAY AREA WITH SEASONABLY COOL WEATHER THROUGH SATURDAY
FOLLOWED BY A GRADUAL WARM UP OVER THE HOLIDAY WEEKEND INTO EARLY
NEXT WEEK.

OVERNIGHT SATELLITE IMAGERY CONTINUES TO SHOW A DIFFUSE MARINE
LAYER TRYING TO DEVELOP WITH PATCHY STRATUS ALONG THE COAST AND
LOCALLY INLAND. SODARS AND THE FT ORD PROFILER PUT THE MARINE
INVERSION 1500-2000 FEET THIS MORNING. THEREFORE...WILL KEEP THE
LOW CLOUDS AND PATCHY FOG THIS MORNING. MODEL GUIDANCE ALSO
SUGGESTS PATCHY DRIZZLE WILL ALSO BE POSSIBLE. THIS MAYBE THE
RESULT OF A PASSING SHORTWAVE TROUGH CURRENTLY VISIBLE ON WATER
VAPOR TO THE SW OF POINT CONCEPTION.

THE MORE NOTABLE WEATHER ITEM TODAY WILL BE THE COOLING
TREND AND SLIGHTLY BELOW NORMAL TEMPS...ESPECIALLY INLAND. THE
AFOREMENTIONED SHORTWAVE TROUGH AND A LONGWAVE TROUGH OVER THE
PAC NW WILL AID IN DROPPING 850MB TEMPS (BY 3C) AND LOWERING 500MB
HEIGHTS OVER THE REGION. THE END RESULT WILL BE A COOL DOWN OF 5
TO 8 DEGREES OVER TUESDAY/S MAX TEMPS...ESPECIALLY AWAY FROM THE
COAST. AFTER THE SHORTWAVE EXITS TO THE EAST LATER TODAY...THE
BROAD LONGWAVE TROUGH WILL KEEP COOL CONDITIONS IN PLACE AS WE
HEAD INTO THE HOLIDAY WEEKEND. PATCHY NIGHT AND MORNING CLOUDS
WILL STILL BE POSSIBLE THE NEXT FEW DAYS. TEMPERATURES WILL
GENERALLY BE IN THE 60S TO NEAR 70 ALONG THE COAST AND 70S TO NEAR
90 INLAND. OVERNIGHT LOWS WILL REMAIN SOMEWHAT MILD AND MOSTLY IN
THE 50S...A FEW POCKETS IN THE 40S IS NOT OUT OF THE QUESTION.

BY THIS WEEKEND...A PAC NW LOW IS FORECAST TO SWING THROUGH THE
NORTHERN PART OF THE STATE BRINGING A SLIGHT CHANCE OF RAIN WELL
NORTH OF THE STATE. AS THE SYSTEM EXITS HIGH PRESSURE WILL
DEVELOP INLAND WITH A THERMAL TROUGH ALONG THE COAST. WEAK TO
MODERATE OFFSHORE FLOW IS FORECAST TO DEVELOP SUNDAY INTO LABOR
DAY. THE OFFSHORE FLOW WILL BRING WARMER TEMPERATURES WITH LITTLE
TO NO MARINE LAYER.

STILL NO SIGN OF PRECIP. THE LATEST CPC 6-10 DAY CALLS FOR NEAR
NORMAL PRECIP WITH ABOVE NORMAL TEMPERATURES.

&&

.AVIATION...AS OF 6:45 AM PDT WEDNESDAY...STRATUS CONTINUES TO
FILL IN OVER THE SFO BAY AREA AND WILL TAKE A WHILE TO CLEAR OUT.
FORECAST IS FOR MVFR CIGS AT SFO THROUGH 18Z POSSIBLY AS LATE AS
19Z.

VICINITY OF KSFO...MVFR THROUGH 18-19Z. WEST WINDS GUSTING TO
25-27 KT THROUGH 06Z.

KSFO BRIDGE APPROACH...SIMILAR TO KSFO.

MONTEREY BAY AREA TERMINALS...STRATUS NOT AS EXTENSIVE THIS
MORNING DUE TO SOME AIRMASS MIXING EARLIER THIS MORNING. AS A
RESULT CIGS SHOULD CLEAR EARLIER. MVFR CIGS THROUGH 18Z.

&&

.MARINE...AS OF 4:50 AM PDT WEDNESDAY...AN UPPER LEVEL TROUGH OFF
THE PACIFIC NORTHWEST WILL DEEPEN AND MOVE INLAND ON SATURDAY.
THIS WILL BRING INCREASING NORTHWEST WINDS OVER THE NORTHERN
WATERS BEGINNING THIS AFTERNOON AND CONTINUING THROUGH SUNDAY.

&&

.MTR WATCHES/WARNINGS/ADVISORIES...
     .TDAY...SCA...PT ARENA TO PT REYES 0-10 NM FROM 2 PM
             SCA...PT REYES TO PIGEON PT 0-10 NM FROM 2 PM

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
453 AM PDT WED SEP 2 2015

.SYNOPSIS...PATCHY DRIZZLE WILL BE POSSIBLE ALONG THE COAST EARLY
WEDNESDAY MORNING. OTHERWISE...DRY WEATHER WILL CONTINUE THROUGH
NEXT WEEK. TEMPERATURES WILL CONTINUE TO COOL THROUGH SATURDAY AS
AN UPPER LEVEL TROUGH DIGS SOUTHWARD INTO THE PACIFIC NORTHWEST.
WARMER AND DRIER CONDITIONS RETURN OVER THE WEEKEND AND EARLY NEXT
WEEK.

&&

.DISCUSSION...AS OF 3:30 AM PDT WEDNESDAY...GENERALLY QUIET
WEATHER WILL CONTINUE FOR THE BAY AREA WITH SEASONABLY COOL
WEATHER THROUGH SATURDAY FOLLOWED BY A GRADUAL WARM UP OVER THE
HOLIDAY WEEKEND INTO EARLY NEXT WEEK.

OVERNIGHT SATELLITE IMAGERY CONTINUES TO SHOW A DIFFUSE MARINE
LAYER TRYING TO DEVELOP WITH PATCHY STRATUS ALONG THE COAST AND
LOCALLY INLAND. SODARS AND THE FT ORD PROFILER PUT THE MARINE
INVERSION 1500-2000 FEET THIS MORNING. THEREFORE...WILL KEEP THE
LOW CLOUDS AND PATCHY FOG THIS MORNING. MODEL GUIDANCE ALSO
SUGGESTS PATCHY DRIZZLE WILL ALSO BE POSSIBLE. THIS MAYBE THE
RESULT OF A PASSING SHORTWAVE TROUGH CURRENTLY VISIBLE ON WATER
VAPOR TO THE SW OF POINT CONCEPTION.

THE MORE NOTABLE WEATHER ITEM TODAY WILL BE THE COOLING
TREND AND SLIGHTLY BELOW NORMAL TEMPS...ESPECIALLY INLAND. THE
AFOREMENTIONED SHORTWAVE TROUGH AND A LONGWAVE TROUGH OVER THE
PAC NW WILL AID IN DROPPING 850MB TEMPS (BY 3C) AND LOWERING 500MB
HEIGHTS OVER THE REGION. THE END RESULT WILL BE A COOL DOWN OF 5
TO 8 DEGREES OVER TUESDAY/S MAX TEMPS...ESPECIALLY AWAY FROM THE
COAST. AFTER THE SHORTWAVE EXITS TO THE EAST LATER TODAY...THE
BROAD LONGWAVE TROUGH WILL KEEP COOL CONDITIONS IN PLACE AS WE
HEAD INTO THE HOLIDAY WEEKEND. PATCHY NIGHT AND MORNING CLOUDS
WILL STILL BE POSSIBLE THE NEXT FEW DAYS. TEMPERATURES WILL
GENERALLY BE IN THE 60S TO NEAR 70 ALONG THE COAST AND 70S TO NEAR
90 INLAND. OVERNIGHT LOWS WILL REMAIN SOMEWHAT MILD AND MOSTLY IN
THE 50S...A FEW POCKETS IN THE 40S IS NOT OUT OF THE QUESTION.

BY THIS WEEKEND...A PAC NW LOW IS FORECAST TO SWING THROUGH THE
NORTHERN PART OF THE STATE BRINGING A SLIGHT CHANCE OF RAIN WELL
NORTH OF THE STATE. AS THE SYSTEM EXITS HIGH PRESSURE WILL
DEVELOP INLAND WITH A THERMAL TROUGH ALONG THE COAST. WEAK TO
MODERATE OFFSHORE FLOW IS FORECAST TO DEVELOP SUNDAY INTO LABOR
DAY. THE OFFSHORE FLOW WILL BRING WARMER TEMPERATURES WITH LITTLE
TO NO MARINE LAYER.

STILL NO SIGN OF PRECIP. THE LATEST CPC 6-10 DAY CALLS FOR NEAR
NORMAL PRECIP WITH ABOVE NORMAL TEMPERATURES.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
202 PM PDT TUE SEP 1 2015

.SYNOPSIS...ASIDE FROM THE POSSIBILITY OF COASTAL DRIZZLE TONIGHT
INTO WEDNESDAY MORNING...DRY WEATHER CONDITIONS WILL PERSIST
THROUGH THE UPCOMING WEEKEND. TEMPERATURES WILL COOL THROUGH LATE
WEEK AS AN UPPER LEVEL TROUGH DIGS SOUTHWARD INTO THE PACIFIC
NORTHWEST. WARMER AND DRIER CONDITIONS RETURN FOR THE UPCOMING
WEEKEND.

&&

.DISCUSSION...AS OF 02:02 PM PDT TUESDAY...COASTAL STRATUS
CONTINUES TO HUG THE COASTLINE FROM POINT REYES SOUTHWARD DOWN
THE BIG SUR COAST AS A RELATIVELY DEEP MARINE LAYER REMAINS IN
PLACE. EXPECTING THE LOW CLOUDS TO SPREAD BACK INLAND LATE IN THE
AFTERNOON OR EARLY EVENING AND PERSIST THROUGH WEDNESDAY MORNING.
MEANWHILE...A WEAK MID/UPPER LEVEL SHORT-WAVE DISTURBANCE CAN BE
SEEN APPROACHING THE REGION FROM THE SOUTHWEST. AS THIS SYSTEM
MOVES ACROSS THE CENTRAL COAST LATE TONIGHT...DRIZZLE APPEARS MORE
LIKELY ALONG THE COAST AND EVEN INTO THE EAST BAY BY WEDNESDAY
MORNING. CANNOT RULE OUT A FEW LOCATIONS PICKING UP A FEW
HUNDREDTHS OF AN INCH.

THE AFOREMENTIONED DISTURBANCE WILL THEN BECOME ABSORBED BY THE
LONG-WAVE TROUGH DROPPING SOUTHWARD ACROSS THE PACIFIC NORTHWEST
BY WEDNESDAY AFTERNOON. THIS APPROACHING TROUGH WILL ALSO RESULT
IN A COOLING TREND REGION-WIDE WEDNESDAY INTO THURSDAY. LINGERING
BOUNDARY LAYER MOISTURE SHOULD KEEP SOME COASTAL CLOUDS ACROSS THE
REGION INTO THURSDAY MORNING BEFORE A STRONGER MID/UPPER LEVEL
TROUGH DIGS INTO THE PACIFIC NORTHWEST/NORTHERN CALIFORNIA LATE
THURSDAY. THIS WILL RESULT IN A COOLING TREND INTO FRIDAY AS 850MB
TEMPERATURES COOL TO AROUND 12-13 DEGREES C. BREEZY NORTHERLY
WINDS CAN ALSO BE EXPECTED ON FRIDAY IN WAKE OF THE FRONTAL
PASSAGE. THE COOLER AND DRIER AIR MASS ADVECTING IN FROM THE NORTH
WILL LIKELY ALLOW OVERNIGHT/MORNING TEMPERATURES TO DROP INTO THE
40S ACROSS THE HILLS/MOUNTAINS DURING THE LATTER HALF OF THE WEEK.
ELSEWHERE...OVERNIGHT LOWS IN THE LOWER 50S WILL BE POSSIBLE AWAY
FROM THE COAST.

BY THE WEEKEND...THE MID/UPPER LEVEL TROUGH WILL SHIFT INLAND AND
EJECT TOWARD THE NORTHEAST. THIS WILL RESULT IN SLIGHT WARMING ON
SATURDAY WITH A MORE ROBUST WARM-UP (BACK ABOVE SEASONAL AVERAGES)
EXPECTED SUNDAY WHEN THE THERMAL SURFACE TROUGH SHIFT TOWARD THE
COAST. THIS SHOULD ALSO ALLOW FOR AT LEAST WEAK OFFSHORE FLOW TO
DEVELOP OVER THE INLAND HILLS/MOUNTAINS THROUGH THE WEEKEND. GIVEN
THE DRY FUELS OVER THE REGION...WILL NEED TO CONTINUE TO MONITOR
THIS PATTERN IN THE COMING DAYS. TEMPERATURES THEN HOLD STEADY
INTO EARLY NEXT WEEK ALONG WITH DRY WEATHER CONDITIONS AS A BROAD
UPPER LEVEL TROUGH REMAINS ALONG THE WEST COAST.

&&

.AVIATION...AS OF 10:54 AM PDT TUESDAY...CLEAR SKIES ARE
PREVAILING OVER THE SAN FRANCISCO BAY TERMINALS THIS MORNING.
MEANWHILE IN MONTEREY ABUNDANT CLOUD COVER PERSISTS OVER THE
TERMINALS. LIGHT ONSHORE FLOW COMBINED WITH A 2000 FOOT DEEP
MARINE LAYER MAY KEEP MONTEREY IN THE CLOUDS ALL DAY.

VICINITY OF KSFO...VFR IS ANTICIPATED TO PREVAIL THROUGH THE NEXT
24 TO 36 HOURS...WITH A PERIOD OF MVFR POSSIBLE BETWEEN 1400 AND
1600Z. HOWEVER...BKN-OVC010 IS ANTICIPATED OVERNIGHT FOR THE
OAKLAND TERMINALS. THE SEA BREEZE WILL REACH 15 KT THIS AFTERNOON
WITH GUSTS TO 20 KT POSSIBLE.

CONFIDENCE IS MODERATE.

KSFO BRIDGE APPROACH...SIMILAR TO KSFO.

MONTEREY BAY AREA TERMINALS...MVFR CIGS ARE EXPECTED TO PREVAIL
TODAY AT KMRY WITH A POSSIBILITY OF VFR BETWEEN 2000 AND 2300Z.
VFR IS ANTICIPATED AT KSNS BEGINNING 1900Z. IF STRATUS DOES MIX
OUT AN EARLY RETURN IS ANTICIPATED THIS AFTERNOON. THE SEA BREEZE
IS EXPECTED TO REACH 8 TO 12 KT THIS AFTERNOON WITH GUSTS TO 18
KT POSSIBLE.

CONFIDENCE IS MODERATE.

&&

.MARINE...AS OF 02:02 PM PDT TUESDAY...A WEAK SURFACE PRESSURE
GRADIENT WILL MAINTAIN GENERALLY LIGHT WINDS OVER A GOOD PORTION
OF THE COASTAL WATERS THROUGH WEDNESDAY AFTERNOON. MODERATE WINDS
ARE HOWEVER EXPECTED TO PERSIST OVER THE NORTHERN OUTER COASTAL
WATERS THROUGH TONIGHT. THE SURFACE PRESSURE GRADIENT IS EXPECTED
TO INCREASE FOR THE SECOND HALF OF THE WEEK...RESULTING IN
STRENGTHENING WINDS.

1043 PM PDT MON AUG 31 2015

.SYNOPSIS...ASIDE FROM THE POSSIBILITY OF COASTAL DRIZZLE THE
NEXT FEW MORNINGS...DRY WEATHER CONDITIONS WILL PERSIST THROUGH
THE WORKWEEK. TEMPERATURES WILL COOL SLIGHTLY FOR THE THE LATTER
HALF OF THE WEEK AS AN UPPER LEVEL TROUGH DROPS SOUTHWARD INTO THE
PACIFIC NORTHWEST.

&&

.DISCUSSION...AS OF 8:50 PM PDT MONDAY...A THERMAL TROUGH AND
MAINLY CLEAR SKIES ACROSS THE REGION TODAY RESULTED IN WARMER
TEMPERATURES OVER MOST LOCATIONS WITH EXCEPTION OF THE COAST WHERE
SLIGHTLY COOLER TEMPERATURES WERE FELT AS A RESULT OF THE TYPICAL
ONSHORE FLOW.

LATEST SATELLITE IMAGERY REVEALS PATCHY LOW CLOUDS BEGINNING TO
FORM ALONG THE COAST AT THIS HOUR. MODELS SHOW INCREASING
BOUNDARY LAYER MOISTURE HOWEVER A ROBUST 4.7 MB GRADIENT FROM
ACV-SFO WILL LIKELY KEEP ANY STRATUS THAT FORMS PATCHY IN NATURE.
DRIZZLE MAY ACCOMPANY PATCHY STRATUS ALONG THE COAST BY MORNING AS
A TROUGH OFF THE COAST DEEPENS AND SHIFT SLIGHTLY TOWARD THE
COAST IN TURN DEEPENING THE MARINE LAYER.

SUNNY SKIES AND SLIGHTLY ABOVE NORMAL TEMPERATURES ARE EXPECTED
ONCE AGAIN TUESDAY AS VERY LITTLE CHANGE IS ANTICIPATED IN THE
OVERALL WEATHER PATTERN. PATCHY COASTAL STRATUS WILL CLEAR TO THE
COAST BY NOON.

FROM PREVIOUS DISCUSSION...BY TUESDAY NIGHT INTO WEDNESDAY
MORNING...ANOTHER WEAK MID/UPPER LEVEL SHORT-WAVE DISTURBANCE IS
FORECAST TO APPROACH THE REGION FROM OUR SOUTHWEST AND ENHANCE THE
POSSIBILITY OF COASTAL DRIZZLE. MEANWHILE...A STRONGER UPPER LEVEL
LOW IS FORECAST TO DROP SOUTHWARD INTO THE PACIFIC
NORTHWEST...COOLING 850 MB TEMPERATURES OVER OUR REGION. THIS WILL
RESULT IN A COOLING TREND OVER THE SAN FRANCISCO/MONTEREY BAY
REGION FOR WEDNESDAY INTO THURSDAY. THE COOLER AND DRIER AIR MASS
ADVECTING SOUTHWARD OVER THE REGION LATE WEEK SHOULD CAUSE THE
MARINE LAYER TO MIX OUT...LIMITING COASTAL CLOUDS AND ENDING THE
POSSIBILITY OF COASTAL DRIZZLE.

DRY CONDITIONS WILL PERSIST INTO THE UPCOMING WEEKEND AS THE
UPPER LEVEL TROUGH AXIS REMAINS STRETCHED ACROSS NORTHERN
CALIFORNIA NORTHWARD INTO THE PACIFIC NORTHWEST. TEMPERATURES WILL
ALSO CONTINUE ON THE COOL SIDE OF NORMAL THROUGH AT LEAST SATURDAY
AFTERNOON. THE TROUGH WILL THEN LIFT TO THE NORTHEAST LATE IN THE
WEEKEND INTO EARLY NEXT WEEK...ALLOWING TEMPERATURE TO REBOUND

FORM ALONG THE COAST AT THIS HOUR. MODELS SHOW INCREASING
BOUNDARY LAYER MOISTURE HOWEVER A ROBUST 4.7 MB GRADIENT FROM
ACV-SFO WILL LIKELY KEEP ANY STRATUS THAT FORMS PATCHY IN NATURE.
DRIZZLE MAY ACCOMPANY PATCHY STRATUS ALONG THE COAST BY MORNING AS
A TROUGH OFF THE COAST DEEPENS AND SHIFT SLIGHTLY TOWARD THE
COAST IN TURN DEEPENING THE MARINE LAYER.

SUNNY SKIES AND SLIGHTLY ABOVE NORMAL TEMPERATURES ARE EXPECTED
ONCE AGAIN TUESDAY AS VERY LITTLE CHANGE IS ANTICIPATED IN THE
OVERALL WEATHER PATTERN. PATCHY COASTAL STRATUS WILL CLEAR TO THE
COAST BY NOON.

FROM PREVIOUS DISCUSSION...BY TUESDAY NIGHT INTO WEDNESDAY
MORNING...ANOTHER WEAK MID/UPPER LEVEL SHORT-WAVE DISTURBANCE IS
FORECAST TO APPROACH THE REGION FROM OUR SOUTHWEST AND ENHANCE THE
POSSIBILITY OF COASTAL DRIZZLE. MEANWHILE...A STRONGER UPPER LEVEL
LOW IS FORECAST TO DROP SOUTHWARD INTO THE PACIFIC
NORTHWEST...COOLING 850 MB TEMPERATURES OVER OUR REGION. THIS WILL
RESULT IN A COOLING TREND OVER THE SAN FRANCISCO/MONTEREY BAY
REGION FOR WEDNESDAY INTO THURSDAY. THE COOLER AND DRIER AIR MASS
ADVECTING SOUTHWARD OVER THE REGION LATE WEEK SHOULD CAUSE THE
MARINE LAYER TO MIX OUT...LIMITING COASTAL CLOUDS AND ENDING THE
POSSIBILITY OF COASTAL DRIZZLE.

DRY CONDITIONS WILL PERSIST INTO THE UPCOMING WEEKEND AS THE
UPPER LEVEL TROUGH AXIS REMAINS STRETCHED ACROSS NORTHERN
CALIFORNIA NORTHWARD INTO THE PACIFIC NORTHWEST. TEMPERATURES WILL
ALSO CONTINUE ON THE COOL SIDE OF NORMAL THROUGH AT LEAST SATURDAY
AFTERNOON. THE TROUGH WILL THEN LIFT TO THE NORTHEAST LATE IN THE

COASTLINE FROM THE GOLDEN GATE TO THE MONTEREY PENINSULA. ADDITIONAL
COASTAL STRATUS AND FOG ALONG WITH SOME INLAND INTRUSION IS FORECAST
OVERNIGHT. SKIES CLEAR BACK TO THE IMMEDIATE COASTLINE TUESDAY...BUT
ONSHORE WINDS WILL PREVAIL AND WILL PICK UP IN STRENGTH BY AFTERNOON

MAY ALSO SEE SOME PATCHY DRIZZLE ALONG THE COAST SOUTH OF THE
GOLDEN GATE THROUGH THE MONTEREY BAY REGION TUESDAY MORNING AS A
WEAK DISTURBANCE MOVES ACROSS AND INTERACTS WITH THE MARINE LAYER.

LITTLE CHANGE IS EXPECTED ON TUESDAY AS THE LONG-WAVE TROUGH
REMAINS OVER MUCH OF THE WEST COAST. TEMPERATURES WILL GENERALLY
BE SIMILAR TO TODAY REGION-WIDE WITH MOSTLY SUNNY CONDITIONS OVER
MOST INLAND LOCATIONS. BY TUESDAY NIGHT INTO WEDNESDAY
MORNING...ANOTHER WEAK MID/UPPER LEVEL SHORT-WAVE DISTURBANCE IS
FORECAST TO APPROACH THE REGION FROM OUR SOUTHWEST AND ENHANCE THE
POSSIBILITY OF COASTAL DRIZZLE. MEANWHILE...A STRONGER UPPER
LEVEL LOW IS FORECAST TO DROP SOUTHWARD INTO THE PACIFIC
NORTHWEST...COOLING 850 MB TEMPERATURES OVER OUR REGION. THIS WILL
RESULT IN A COOLING TREND OVER THE SAN FRANCISCO/MONTEREY BAY
REGION FOR WEDNESDAY INTO THURSDAY. THE COOLER AND DRIER AIR MASS
ADVECTING SOUTHWARD OVER THE REGION LATE WEEK SHOULD CAUSE THE
MARINE LAYER TO MIX OUT...LIMITING COASTAL CLOUDS AND ENDING THE
POSSIBILITY OF COASTAL DRIZZLE.

DRY CONDITIONS WILL PERSIST INTO THE UPCOMING WEEKEND AS THE
UPPER LEVEL TROUGH AXIS REMAINS STRETCHED ACROSS NORTHERN
CALIFORNIA NORTHWARD INTO THE PACIFIC NORTHWEST. TEMPERATURES WILL
ALSO CONTINUE ON THE COOL SIDE OF NORMAL THROUGH AT LEAST SATURDAY
AFTERNOON. THE TROUGH WILL THEN LIFT TO THE NORTHEAST LATE IN THE
WEEKEND INTO EARLY NEXT WEEK...ALLOWING TEMPERATURE TO REBOUND
BACK TO NEAR SEASONAL AVERAGES.

ITSELF AFTER A FEW DAYS OF BEING WELL MIXED. THE COMBINATION OF
THE MARINE LAYER AND SIGNIFICANT NORTHERLY FLOW WILL PROMOTE AN
EARLY STRATUS RETURN TO THE MONTEREY AREA...BUT WILL RESULT IN A

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
242 PM PDT MON AUG 31 2015

.SYNOPSIS...ASIDE FROM THE POSSIBILITY OF COASTAL DRIZZLE THE
NEXT FEW MORNINGS...DRY WEATHER CONDITIONS WILL PERSIST THROUGH
THE WORKWEEK. TEMPERATURES WILL COOL SLIGHTLY FOR THE THE LATTER
HALF OF THE WEEK AS AN UPPER LEVEL TROUGH DROPS SOUTHWARD INTO THE
PACIFIC NORTHWEST.

&&

.DISCUSSION...AS OF 02:40 PM PDT MONDAY...TEMPERATURES ARE
GENERALLY A BIT WARMER THIS AFTERNOON OVER INLAND AREAS COMPARED
TO YESTERDAY...WHILE LOCATIONS NEAR THE COAST ARE SLIGHTLY COOLER
AS A RESULT OF PERSISTENT ONSHORE FLOW. IN ADDITION...THE LATEST
FORT ORD PROFILER SHOWS SIGNS OF A SHALLOW MARINE LAYER
REDEVELOPING. THIS IS ALSO REPRESENTATIVE OF THE LOW CLOUDS ALONG
THE SAN MATEO COASTLINE SOUTHWARD. GIVEN THIS AND THE EXPECTED
INCREASE IN BOUNDARY LAYER MOISTURE TONIGHT...LOW CLOUDS WILL
LIKELY BECOME MORE WIDESPREAD LATE TONIGHT INTO TUESDAY MORNING.

.DISCUSSION...AS OF 09:00 AM PDT MONDAY...VISIBLE SATELLITE
IMAGERY THIS MORNING SHOWS STRATUS ALONG THE SAN MATEO COAST DOWN
AROUND THE MONTEREY BAY REGION. MOST INLAND AREAS SHOULD SEE
CLEARING LATER THIS MORNING WITH MOSTLY SUNNY CONDITIONS THROUGH
THE AFTERNOON. TEMPERATURES THIS AFTERNOON WILL GENERALLY BE NEAR
OR A FEW DEGREES ABOVE THOSE FROM SUNDAY...UPPER 60S TO LOWER 70S
NEAR THE COAST TO THE MID/UPPER 80S IN THE WARMEST INLAND
LOCATIONS. HAVE MADE A FEW MINOR ADJUSTMENTS TO THE SKY COVER AND

OFF THE SAN MATEO COAST HEADING TO THE SOUTH. THIS AREA WILL
LIKELY EXPEND OVER THE NEXT FEW HOURS AND IMPACT AT LEAST SOUTHERN
MONTEREY BAY COASTLINE. OUTSIDE OF THAT...SHOULD BE A MOSTLY
SUNNY START TO THE DAY. TEMPS ARE RUNNING CLOSE TO WHERE WE WERE
YESTERDAY AND HIGHS ARE EXPECTED TO BE CLOSE TO THE VALUES WE HIT
ON SUNDAY. LOOK FOR UPPER 60S TO UPPER 70S AT THE COAST WITH UPPER
70S TO NEAR 90 FOR INLAND SPOTS. ONE DIFFERENCE FROM YESTERDAY IS
WINDS FOR THE AFTERNOON SHOULD BE SLIGHTLY LESS ALTHOUGH WE WILL
STILL SEE LOCAL GUSTS TO AROUND 30 MPH.

FOR THE REST OF THE WEEK QUIET WEATHER IS EXPECTED AS THE OVERALL
SYNOPTIC PATTERN HAS A LONGWAVE TROF OVER THE WESTERN THIRD OF THE
CONUS WHILE A RIDGE AXIS IS EXPECTED OVER THE EASTERN THIRD. THIS
WILL PRODUCE TEMPS AT OR A BIT COOLER THAN NORMAL INLAND WHILE
COASTAL SPOTS WILL BE AT OR SLIGHTLY ABOVE NORMAL DUE TO OFFSHORE
FLOW AND ABUNDANT SUNSHINE. THE STORM TRACK WILL REMAIN WELL TO

OFF THE SAN MATEO COAST HEADING TO THE SOUTH. THIS AREA WILL
LIKELY EXPEND OVER THE NEXT FEW HOURS AND IMPACT AT LEAST SOUTHERN
MONTEREY BAY COASTLINE. OUTSIDE OF THAT...SHOULD BE A MOSTLY

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
318 AM PDT MON AUG 31 2015

.SYNOPSIS...GENERALLY DRY WEATHER CONDITIONS WILL PERSIST ACROSS THE
REGION THROUGH THE UPCOMING WORK WEEK. DAYTIME TEMPERATURES NEAR
THE COAST WILL CONTINUE TO BE NEAR NORMAL...WHILE INLAND AREAS
WILL BE SLIGHTLY BELOW SEASONAL AVERAGES.

&&

.DISCUSSION...AS OF 3:15 AM PDT MONDAY...A STRONG NORTHERLY
SURFACE FLOW THIS MORNING HAS HELPED TO KEEP VIRTUALLY OUR ENTIRE
AREA CLOUD FREE SO FAR. LAST FEW FRAMES SHOW ONE PATCH OF CLOUDS
OFF THE SAN MATEO COAST HEADING TO THE SOUTH. THIS AREA WILL
LIKELY EXPEND OVER THE NEXT FEW HOURS AND IMPACT AT LEAST SOUTHERN
MONTEREY BAY COASTLINE. OUTSIDE OF THAT...SHOULD BE A MOSTLY
SUNNY START TO THE DAY. TEMPS ARE RUNNING CLOSE TO WHERE WE WERE
YESTERDAY AND HIGHS ARE EXPECTED TO BE CLOSE TO THE VALUES WE HIT
ON SUNDAY. LOOK FOR UPPER 60S TO UPPER 70S AT THE COAST WITH UPPER
70S TO NEAR 90 FOR INLAND SPOTS. ONE DIFFERENCE FROM YESTERDAY IS
WINDS FOR THE AFTERNOON SHOULD BE SLIGHTLY LESS ALTHOUGH WE WILL
STILL SEE LOCAL GUSTS TO AROUND 30 MPH.

FOR THE REST OF THE WEEK QUIET WEATHER IS EXPECTED AS THE OVERALL
SYNOPTIC PATTERN HAS A LONGWAVE TROF OVER THE WESTERN THIRD OF THE
CONUS WHILE A RIDGE AXIS IS EXPECTED OVER THE EASTERN THIRD. THIS
WILL PRODUCE TEMPS AT OR A BIT COOLER THAN NORMAL INLAND WHILE
COASTAL SPOTS WILL BE AT OR SLIGHTLY ABOVE NORMAL DUE TO OFFSHORE
FLOW AND ABUNDANT SUNSHINE. THE STORM TRACK WILL REMAIN WELL TO
OUR NORTH.

FURTHER OUT...NO SIGN OF RAIN THROUGH AT LEAST THE MIDDLE OF NEXT
WEEK.
&&

.AVIATION...AS OF 10:42 PM PDT SUNDAY...THE MESOSCALE MODEL
OUTPUT IS STILL HAVING TROUBLE RESOLVING THE PRESENT STRENGTH OF
THE NORTHERLY SURFACE PRESSURE GRADIENT OVER THE NORTH BAY AS WELL
AS FROM ACV-SFO. BOTH GRADIENTS HAVE CLIMBED THROUGH THE AFTERNOON
AND EVENING FOLLOWING THE PASSAGE OF THE DRY TROUGH EARLIER. THE
UKI-STS GRADIENT IS HOLDING STRONG AT 2.6 MB AND THE ACV-SFO IS
MODERATE AT 4.4 MB. BOTH ARE FORECAST TO HOLD CLOSE TO WHERE THEY

.SYNOPSIS...GENERALLY DRY WEATHER CONDITIONS WILL PERSIST ACROSS THE
REGION THROUGH THE UPCOMING WORK WEEK. DAYTIME TEMPERATURES NEAR
THE COAST WILL CONTINUE TO BE NEAR NORMAL...WHILE INLAND AREAS
WILL BE SLIGHTLY BELOW SEASONAL AVERAGES.

&&

.DISCUSSION...AS OF 8:35 PM PDT SUNDAY...A DRY SHORTWAVE TROUGH
SWEPT ACROSS NORTHERN CALIFORNIA THIS AFTERNOON. BEHIND THIS
TROUGH...LOCALLY GUSTY WEST TO NORTHWEST WINDS DEVELOPED. WINDS
WERE GUSTING AS HIGH AS 37 MPH AT SAN FRANCISCO AIRPORT THIS
EVENING. THESE BRISK WINDS HAVE RESULTED IN GOOD LOW LEVEL MIXING
AND HAVE HELPED LIMIT COASTAL LOW CLOUD FORMATION THIS EVENING.
EXPECT LOW CLOUDS TO INCREASE SOMEWHAT OVERNIGHT AS WINDS
EASE...BUT LOW CLOUDS AND NOT EXPECTED TO BECOME WIDESPREAD. A
FORECAST UPDATE EARLIER THIS EVENING INCLUDED A REDUCTION IN LOW
CLOUDS LATE TONIGHT AND MONDAY MORNING...ESPECIALLY FOR INLAND
AREAS.

WINDS BEHIND THE SHORTWAVE TROUGH HAD ENOUGH OF A NORTHERLY
COMPONENT TO PRODUCE DOWNSLOPE WARMING IN THE NORTH BAY VALLEYS
THIS AFTERNOON. THE SONOMA COUNTY AIRPORT HAD AN AFTERNOON HIGH OF
90 DEGREES...WHICH WAS THE WARMEST SPOT IN THE BAY AREA TODAY.

LITTLE CHANGE IS FORECAST THROUGH MONDAY. TEMPERATURES ARE
FORECAST TO BE NEAR SEASONAL NORMS AND MOST SUNNY SKIES WILL
PREVAIL AFTER PATCHY MORNING LOW CLOUDS CLEAR.

AN UPPER LEVEL TROUGH CURRENTLY CENTERED NEAR THE ALASKAN
PANHANDLE IS FORECAST TO GRADUALLY DIG SOUTH ALONG THE WEST COAST
THROUGH MIDWEEK. NIGHT AND MORNING LOW CLOUDS WILL PROBABLY BECOME
MORE WIDESPREAD FROM MONDAY NIGHT THROUGH WEDNESDAY MORNING...AND
PATCHY LATE NIGHT AND EARLY MORNING COASTAL DRIZZLE IS POSSIBLE.
OTHERWISE...NO PRECIPITATION IS EXPECTED. TEMPERATURES WILL
LIKELY DIP BELOW NORMAL BY MIDWEEK...ESPECIALLY ACROSS INLAND
AREAS.

THE MEDIUM RANGE MODELS AGREE THAT THE UPPER TROUGH WILL LIFT TO
THE NORTHEAST LATE IN THE WEEK...ALLOWING FOR A WARMING TREND
NEXT WEEKEND.

AREAS.

WINDS BEHIND THE SHORTWAVE TROUGH HAD ENOUGH OF A NORTHERLY
COMPONENT TO PRODUCE DOWNSLOPE WARMING IN THE NORTH BAY VALLEYS
THIS AFTERNOON. THE SONOMA COUNTY AIRPORT HAD AN AFTERNOON HIGH OF
90 DEGREES...WHICH WAS THE WARMEST SPOT IN THE BAY AREA TODAY.

LITTLE CHANGE IS FORECAST THROUGH MONDAY. TEMPERATURES ARE
FORECAST TO BE NEAR SEASONAL NORMS AND MOST SUNNY SKIES WILL
PREVAIL AFTER PATCHY MORNING LOW CLOUDS CLEAR.

AN UPPER LEVEL TROUGH CURRENTLY CENTERED NEAR THE ALASKAN
PANHANDLE IS FORECAST TO GRADUALLY DIG SOUTH ALONG THE WEST COAST
THROUGH MIDWEEK. NIGHT AND MORNING LOW CLOUDS WILL PROBABLY BECOME
MORE WIDESPREAD FROM MONDAY NIGHT THROUGH WEDNESDAY MORNING...AND
PATCHY LATE NIGHT AND EARLY MORNING COASTAL DRIZZLE IS POSSIBLE.
OTHERWISE...NO PRECIPITATION IS EXPECTED. TEMPERATURES WILL
LIKELY DIP BELOW NORMAL BY MIDWEEK...ESPECIALLY ACROSS INLAND
AREAS.

THE MEDIUM RANGE MODELS AGREE THAT THE UPPER TROUGH WILL LIFT TO
THE NORTHEAST LATE IN THE WEEK...ALLOWING FOR A WARMING TREND
NEXT WEEKEND.

&&

.AVIATION...AS OF 5:27 PM PDT SUNDAY...A FAIRLY VIGOROUS SURFACE
TROUGH IS PRESENTLY SLIDING SOUTH OVER THE FORECAST AREA. A WEST-
EAST ORIENTED BRIGHTNESS DISCONTINUITY (HAZY VERSUS NON-HAZY
CONDITIONS) CAN BE SEEN IN THE VICINITY OF THE TROUGH ON THE VISIBLE
IMAGERY LOOP IN ADDITION TO PATCHY COASTAL STRATUS CLOUDS DEVELOPING
IN THE AREA OF GREATEST SURFACE CONVERGENCE IN FRONT OF THE TROUGH.
THE TROUGH WILL CONTINUE TO SLIDE SOUTH OVER THE AREA THIS EVENING
PER THE GFS MODEL. IN ITS WAKE A DRIER AIR MASS WILL SETTLE IN
TENDING TO SLOW THE REDEVELOPMENT OF STRATUS AND FOG TONIGHT.

VICINITY OF KSFO...VFR. WESTERLY WIND GUSTS TO 30 KNOTS TIL 04Z.

FROM TIME TO TIME TODAY. WEST NORTHWESTERLY WINDS ARE EXPECTED TO
INCREASE THIS AFTERNOON WHICH SHOULD FURTHER DISRUPT RIP CURRENT
DEVELOPMENT.

PREVAIL ACROSS THE REGION THIS AFTERNOON WITH TEMPERATURES
GENERALLY IN THE 70S TO LOWER 80S IN THE WARMER INLAND AREAS.
WHILE LOW LEVEL CLOUDS ARE PATCHY AT BEST OVER THE COASTAL
WATERS...DO EXPECT AN INCREASE IN COVERAGE NEAR THE COAST
OVERNIGHT TONIGHT AS BOUNDARY LAYER MOISTURE IS FORECAST TO
REBOUND. OTHERWISE...A MID/UPPER LEVEL LONG-WAVE TROUGH IS
FORECAST TO PERSIST OVER MUCH OF THE WEST COAST THROUGH THE FIRST
HALF OF THE WEEK. THIS WILL RESULT IN NEAR SEASONAL TEMPERATURES
AND GENERALLY DRY WEATHER CONDITIONS. HOWEVER...HAVE ADDED A
MENTION OF COASTAL DRIZZLE TUESDAY MORNING AND WEDNESDAY MORNING
AS THE MARINE LAYER COMPRESSES AND A SERIES OF WEAK SHORT-WAVE
DISTURBANCES MOVE ACROSS THE REGION.

THE AFOREMENTIONED DISTURBANCES WILL HELP TO REINFORCE THE BROAD
TROUGH ALONG THE WEST COAST AND ADVECT A SLIGHTLY COOLER AIR MASS
DOWN ACROSS THE REGION BY MIDWEEK. THIS WILL BRING INLAND
TEMPERATURES BACK DOWN A FEW DEGREES TO BELOW SEASONAL AVERAGES.
MEANWHILE...LIMITED MOISTURE ALOFT WILL GENERALLY MAINTAIN DRY
WEATHER CONDITIONS REGION-WIDE (ASIDE FROM THE POTENTIAL FOR
COASTAL DRIZZLE TUESDAY AND WEDNESDAY MORNINGS).

SHIFTS INLAND. HOWEVER...BOTH THE LATEST GFS AND ECMWF MODELS SHOW
THIS PATTERN SHIFT TO OCCUR LATER (LATE INTO NEXT WEEKEND). WITH
THIS...WILL SHOW TEMPERATURES WARMING A FEW DEGREES FROM THOSE ON

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
1112 AM PDT SUN AUG 30 2015

.SYNOPSIS...A DRY UPPER TROUGH WILL REMAIN ANCHORED NEAR THE WEST
COAST THROUGH MOST OF THE WEEK. TEMPERATURES NEAR THE COAST WILL
BE NEAR SEASONAL NORMS...WHILE INLAND AREAS WILL GENERALLY BE
COOLER THAN NORMAL OVER THE NEXT SEVEN DAYS. NO RAIN IS EXPECTED.

&&

.DISCUSSION...AS OF 09:02 AM PDT SUNDAY...QUIET WEATHER CONDITIONS
ACROSS THE REGION THIS MORNING AS A BROAD MID/UPPER LEVEL TROUGH
REMAINS OVER MUCH OF THE WEST COAST. LOW CLOUDS AT THIS HOUR ARE
GENERALLY CONFINED TO THE MARIN...SAN FRANCISCO AND SAN MATEO
COASTLINE. HAVE MADE A FEW ADJUSTMENTS TO THE SKY COVER TO REFLECT
CURRENT TRENDS. OTHERWISE...THE FORECAST REMAINS ON TRACK FOR
TODAY. TEMPERATURES NEAR THE COAST WILL BE NEAR SEASONAL AVERAGES
UNDER MOSTLY SUNNY SKIES...WHILE INLAND AREAS WILL BE A BIT COOLER
THAN WHAT`S NORMAL FOR LATE AUGUST.

&&

.PREV DISCUSSION...AS OF 3:10 AM PDT SUNDAY...THANKS TO A COLD
FRONT THAT SWEPT ACROSS OUR REGION YESTERDAY DRIER AND COOLER AIR
HAS SETTLED ACROSS OUR AREA TODAY. MANY LOCATIONS ARE RUNNING 5 TO
10 DEGREES COOLER COMPARED TO YESTERDAY WHILE DEWPOINTS ARE ALSO
RUNNING 5 TO 10 DEGREES DRIER IN MANY SPOTS. SATELLITE PRODUCT
SHOWS PATCHY CLOUDS BOTH ALONG THE COAST...INTO THE EAST BAY AND
SANTA CLARA VALLEY. WOULD EXPECT THEM TO BURN-OFF FAIRLY FAST
LEADING TO MOSTLY SUNNY CONDITIONS BY AFTERNOON. HIGHS WILL BE IN
THE UPPER 60S TO UPPER 70S AT THE COAST WITH 80S FOR MOST INLAND
SPOTS. NORTHWESTERLY WINDS ARE EXPECTED TO INCREASE THROUGH THE
DAY. MANY SPOTS COULD SEE GUSTS OF AT LEAST 15 MPH BY THE
AFTERNOON WITH LOCALLY HIGHER VALUES EXPECTED.

OVERALL LOOKS LIKE A VERY QUIET WEEK FOR OUR REGION AS
SYNOPTICALLY A LONGWAVE TROF WILL BE CENTERED OVER THE WESTERN
CONUS WHILE A RIDGE OF HIGH PRESSURE REMAINS OVER THE EAST. TEMPS
WILL GENERALLY BE AT TO A BIT BELOW NORMAL INLAND WHILE COASTAL
SPOTS WILL BE AT OR SLIGHTLY ABOVE NORMAL. OVERNIGHT CLOUD COVER
IS EXPECTED TO INCREASE EACH NIGHT AS THE MARINE LAYER DEEPENS AND
THE ONSHORE FLOW SLIGHTLY INCREASES. THE STORM TRACK WILL STAY
WELL TO THE NORTH THROUGH THE PERIOD.

TEMPS WILL REBOUND A BIT BY THE END OF THE WEEK AS THE TROF SHIFTS
TO THE NORTH AND EAST. NO INDICATION OF RAIN RETURNING TO OUR
AREA THROUGH AT LEAST THE MIDDLE OF NEXT WEEK.

&&

.AVIATION...AS OF 11:11 AM PDT SUNDAY...MOSTLY CLEAR SKIES ARE
BEING REPORTED ACROSS THE FORECAST AREA THIS MORNING. THE CURRENT
VISIBLE SATELLITE IMAGE IS SOME PASSING HIGH CLOUDS BUT LITTLE TO
NO OFFSHORE STRATUS FIELD. THE FORT ORD PROFILER IS INDICATING A
DEEP LAYER OF MARINE AIR IN PLACE WITH NO REAL LOW LEVEL
INVERSION. FORECAST MODELS INDICATE AN EARLIER RETURN OF STRATUS
TONIGHT SO HAVE MOVED UP THE TIME FOR RETURN IN THE FORECAST.

VICINITY OF KSFO...VFR IS EXPECTED TO PREVAIL THROUGH AROUND 0900Z
AT WHICH POINT MVFR BKN-OVC015 IS ANTICIPATED. FIRST GUESS AT
TOMORROW MORNING BURN OFF IS 1700Z. THIS AFTERNOON`S SEA BREEZE IS
EXPECTED TO REACH 15 TO 20 KT WITH GUSTS TO 25 KT.

CONFIDENCE IS MODERATE.

KSFO BRIDGE APPROACH...SIMILAR TO KSFO.

MONTEREY BAY AREA TERMINALS...VFR IS EXPECTED TO PREVAIL THROUGH AROUND
0500Z AT WHICH POINT MVFR BKN-OVC015 IS ANTICIPATED. IFR WILL BE
POSSIBLE BEGINNING AROUND 1100Z. FIRST GUESS AT TOMORROW MORNING
BURN OFF IS 1700Z. THIS AFTERNOON`S SEA BREEZE IS EXPECTED TO
REACH 10 TO 15 KT WITH GUSTS TO 22 KT POSSIBLE.

CONFIDENCE IS MODERATE.

&&

.BEACHES...AS OF 11:10 AM PDT SUNDAY...BUOY REPORTS THIS MORNING
ARE SHOWING A MIX OF LOCAL WIND WAVES AND LONG PERIOD WESTERLY
SWELL. ALTHOUGH THIS IS NOT THE IDEAL SCENARIO FOR RIP CURRENT
DEVELOPMENT CAN`T RULE OUT SOME STRONGER RIP CURRENTS FLARING UP
FROM TIME TO TIME TODAY. WEST NORTHWESTERLY WINDS ARE EXPECTED TO
INCREASE THIS AFTERNOON WHICH SHOULD FURTHER DISRUPT RIP CURRENT
DEVELOPMENT.

&&

.MARINE...AS OF 09:02 AM PDT SUNDAY...THE SURFACE PRESSURE
GRADIENT IS EXPECTED TO STRENGTHEN ALONG THE COAST
TODAY...PROMOTING INCREASING NORTHWESTERLY WINDS. THESE
STRENGTHENING WINDS WILL RESULT IN DETERIORATING SEA CONDITIONS.

&&

.MTR WATCHES/WARNINGS/ADVISORIES...
     .TDAY...SCA...PT ARENA TO PIGEON PT 10-60 NM FROM 3 PM
             SCA...PT PINOS TO PT PIEDRAS BLANCAS 0-10 NM
