AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
120 PM PDT MON SEP 1 2014

.SYNOPSIS...TEMPERATURES RETURN TO NEAR SEASONAL AVERAGES BY TUESDAY
AND WILL PERSIST THROUGH LATE WEEK ALONG WITH DRY WEATHER CONDITIONS.

&&

.DISCUSSION...AS OF 01:18 PM PDT MONDAY...THE 12Z UPPER AIR
SOUNDING FROM OAKLAND THIS MORNING SHOWED WEAK OFFSHORE FLOW IN
THE 2-6KFT LAYER THAT RESULTED IN WARMER TEMPERATURES ALOFT. THIS
HAS GENERALLY TRANSLATED TO A WARM UP IN SURFACE TEMPERATURES AS
EXPECTED WITH A MID/UPPER LEVEL RIDGE AXIS ALSO STRETCHING ACROSS
THE REGION. THE FORT ORD PROFILER IS ALSO SHOWING THESE WARMER
TEMPERATURES ABOVE THE MARINE LAYER...WHICH HAS KEPT COASTAL
CLOUDS JUST OFF THE CENTRAL COAST. GIVEN A DEEPENING MARINE
LAYER...SHOULD SEE DEVELOPMENT OF COASTAL CLOUDS LATE THIS EVENING
THAT WILL LIKELY SPREAD INLAND OVERNIGHT.

SLIGHTLY COOLER TEMPERATURES ARE THEN EXPECTED FOR TOMORROW AS THE
RIDGE WEAKENS AHEAD OF THE NEXT MID/UPPER LEVEL TROUGH SET TO DROP
SOUTHWARD OUT OF THE GULF OF ALASKA AND DOWN INTO THE PACIFIC
NORTHWEST DURING THE NEXT COUPLE OF DAYS. IN ADDITION...ONSHORE FLOW
AND DEEPENING MARINE LAYER WILL HELP BRING TEMPERATURES BACK TO NEAR
SEASONAL AVERAGES BY TUESDAY. THE FORECAST MODELS CONTINUE TO KEEP A
LINGERING TROUGH DRAPED OVER THE REGION THROUGH LATE WEEK. WITH
LIMITED MOISTURE TO WORK WITH...NOT EXPECTING ANY MEASURABLE
PRECIPITATION THROUGH THE EXTENDED FORECAST PERIOD AND TEMPERATURES
WILL BE WITHIN A FEW DEGREES OF NORMAL.

THE MEDIUM RANGE MODELS DO NOT SHOW MUCH CHANGE IN THE UPPER LEVEL
PATTERN AS WE HEAD INTO NEXT WEEKEND. WITH THIS...WILL CONTINUE TO
KEEP TEMPERATURES NEAR WHAT IS TYPICAL FOR LATE SUMMER AND KEEP ANY
MENTION OF PRECIPITATION OUT OF THE EXTENDED FORECAST.

&&

.AVIATION...AS OF 10:20 AM PDT MONDAY...PATCHY STRATUS CONFINED TO
AREAS ALONG THE COAST THIS MORNING AND ALL TERMINALS CLEAR.
NORTHERLY GRADIENT IS SET TO WEAKEN HOWEVER WITH SOMEWHAT SHALLOW
MARINE LAYER STRATUS LIKELY TO BE PATCHY AGAIN TONIGHT.

VICINITY OF KSFO...VFR TODAY. WEST WINDS TO AROUND 15 KT. STRATUS
TONIGHT EXPECTED TO BE PATCHY AND MOSTLY CONFINED TO COAST AND
EAST BAY.

KSFO BRIDGE APPROACH...SIMILAR TO KSFO.

MONTEREY BAY AREA TERMINALS...VFR TODAY. LIGHT TO MODERATE SEA
BREEZE. STRATUS TO RETURN LATE EVENING.

&&

.MARINE...AS OF 01:18 PM PDT MONDAY...HIGH PRESSURE EXTENDS FROM
THE EASTERN PACIFIC INTO THE PACIFIC NORTHWEST. MODERATE NORTHWEST
WINDS CONTINUE ALONG THE CALIFORNIA COAST. THE WINDS WILL DECREASE
OVER THE SOUTHERN WATERS TUESDAY THROUGH THURSDAY AS A THERMAL
TROUGH DEVELOPS ALONG THE COAST.

&&

.MTR WATCHES/WARNINGS/ADVISORIES...
     .TNGT...SCA...PT ARENA TO PT REYES 10-60 NM
             SCA...PT ARENA TO PT REYES 0-10 NM UNTIL 9 PM

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
1024 AM PDT MON SEP 1 2014

.SYNOPSIS...HIGH PRESSURE BUILDING ALONG THE CALIFORNIA COAST
WILL RESULT IN MOSTLY SUNNY SKIES AND WARM AFTERNOON TEMPERATURES
ON LABOR DAY. TEMPERATURES WILL THEN COOL ON TUESDAY AND WEDNESDAY
AS AN UPPER TROUGH DEVELOPS NEAR THE WEST COAST. DRY CONDITIONS
WILL PREVAIL EXCEPT FOR POSSIBLE PATCHY NIGHT AND MORNING DRIZZLE
IN COASTAL AREAS AROUND MIDWEEK.

&&

.DISCUSSION...AS OF 09:21 AM PDT MONDAY...THE FORT ORD PROFILER
THIS MORNING SHOWS A SLIGHTLY DEEPER MARINE LAYER IN PLACE ACROSS
THE REGION. AS A RESULT... COASTAL CLOUDS FORMED OVERNIGHT OFF
THE SAN MATEO COAST SOUTHWARD AND SPREAD INLAND DOWN THE SALINAS
VALLEY. AROUND THE SAN FRANCISCO BAY...GENERALLY CLEAR SKIES
PREVAIL THIS MORNING. SHOULD SEE BURN-OFF OF INLAND CLOUDS BY LATE
MORNING WITH PLENTY OF SUNSHINE ACROSS THE REGION. INLAND
TEMPERATURES THIS AFTERNOON WILL BE A FEW TO SEVERAL DEGREES ABOVE
SEASONAL AVERAGES IN RESPONSE TO A MID/UPPER LEVEL HIGH PRESSURE
OVERHEAD. MADE MINOR CHANGES TO THE FORECAST TO REFLECT TRENDS IN
THE CLOUD COVER PER VISIBLE SATELLITE IMAGERY. OTHERWISE...THE
FORECAST LOOKS ON TRACK FOR THE REMAINDER OF THE AFTERNOON.

&&

.PREV DISCUSSION...AS OF 3:35 AM PDT MONDAY...UPPER LEVEL RIDGING
OVER SOUTHERN AND CENTRAL CALIFORNIA WILL PRODUCE WARM WEATHER
CONDITIONS ACROSS OUR REGION ON THIS LABOR DAY. THE FORT ORD
PROFILER SHOWS THAT THE MARINE LAYER HAS BEEN COMPRESSED TO A
DEPTH OF LESS THAN 500 FEET EARLY THIS MORNING AND SATELLITE
REVEALS ONLY PATCHY LOW CLOUDS...MAINLY NEAR MONTEREY BAY. ONSHORE
PRESSURE GRADIENTS HAVE DECREASED SINCE YESTERDAY MORNING AND SOME
LOCATIONS IN THE HILLS ARE EXPERIENCING LIGHT EASTERLY WINDS. ALL
OF THESE FACTORS POINT TO A WARMER DAY TODAY WITH AFTERNOON HIGHS
LIKELY TO BE SEVERAL DEGREES ABOVE NORMAL IN MOST AREAS.

WATER VAPOR SATELLITE IMAGERY CURRENTLY SHOWS AN UPPER LEVEL
TROUGH MOVING THROUGH THE GULF OF ALASKA. THIS TROUGH IS FORECAST
TO DROP TO THE SE ALONG THE BC COAST TONIGHT AND THEN SLIDE
THROUGH THE PAC NW TUESDAY AND TUESDAY NIGHT. THIS WILL TRIGGER
AN INCREASE IN ONSHORE FLOW ACROSS OUR REGION ON TUESDAY AS WELL
AS AN INCREASE IN THE DEPTH OF THE MARINE LAYER. THE RESULT WILL
BE COOLER CONDITIONS ON TUESDAY...AS MUCH AS TEN DEGREES COOLER
FOR INLAND AREAS COMPARED TO TODAY.

THE BULK OF THE ENERGY WITH THE INCOMING UPPER TROUGH WILL MOVE
RAPIDLY EAST ALONG THE U.S.-CANADIAN BORDER ON TUESDAY NIGHT AND
WEDNESDAY. HOWEVER...THE TAIL END OF THIS TROUGH IS FORECAST TO
LINK UP WITH A WEAK MID/UPPER LEVEL CYCLONIC CIRCULATION CENTER
CURRENTLY WELL OFFSHORE ALONG 140W (REMNANTS OF MARIE) AND FORM A
WEAK UPPER LEVEL TROUGH NEAR THE NORTHERN CA COAST BY MIDWEEK.
THIS TROUGH WILL THEN PERSIST THROUGH THE REMAINDER OF THE WEEK
AND PERHAPS INTO NEXT WEEKEND AS WELL. THERE DOES NOT APPEAR TO
BE SUFFICIENT MOISTURE WITH THE MARIE REMNANTS TO PRODUCE ANY
REAL CHANCE OF PRECIPITATION. HOWEVER...BY TUESDAY NIGHT THERE
MAY BE SUFFICIENT LOW LEVEL MOISTURE AND LIFT WITHIN A MUCH
DEEPER MARINE LAYER TO PRODUCE PATCHY DRIZZLE ALONG OUR
COAST...PARTICULARLY ALONG SOUTHWEST-FACING COASTAL TERRAIN AS
LOW LEVEL FLOW WILL BY THEN TAKE ON A SOUTHERLY COMPONENT. HAVE
ADDED VERY LOW POPS AND PATCHY DRIZZLE TO THE FORECAST FOR
COASTAL AREAS FOR LATE TUESDAY NIGHT/WEDNESDAY MORNING AND AGAIN
WEDNESDAY NIGHT/THURSDAY MORNING.

ALTHOUGH WEAK UPPER LEVEL TROUGHING IS EXPECTED TO CONTINUE
ACROSS NORTHERN CALIFORNIA THROUGH NEXT WEEKEND...THE UPPER
TROUGH AXIS IS FORECAST TO SHIFT INLAND WHICH SHOULD ALLOW FOR
MODEST WARMING BY FRIDAY OR SATURDAY.

&&

.AVIATION...AS OF 10:20 AM PDT MONDAY...PATCHY STRATUS CONFINED TO

TROUGH MOVING THROUGH THE GULF OF ALASKA. THIS TROUGH IS FORECAST
TO DROP TO THE SE ALONG THE BC COAST TONIGHT AND THEN SLIDE
THROUGH THE PAC NW TUESDAY AND TUESDAY NIGHT. THIS WILL TRIGGER AN
INCREASE IN ONSHORE FLOW ACROSS OUR REGION ON TUESDAY AS WELL AS
AN INCREASE IN THE DEPTH OF THE MARINE LAYER. THE RESULT WILL BE
COOLER CONDITIONS ON TUESDAY...AS MUCH AS TEN DEGREES COOLER FOR
INLAND AREAS COMPARED TO TODAY.

THE BULK OF THE ENERGY WITH THE INCOMING UPPER TROUGH WILL MOVE
RAPIDLY EAST ALONG THE U.S.-CANADIAN BORDER ON TUESDAY NIGHT AND
WEDNESDAY. HOWEVER...THE TAIL END OF THIS TROUGH IS FORECAST TO
LINK UP WITH A WEAK MID/UPPER LEVEL CYCLONIC CIRCULATION CENTER
CURRENTLY WELL OFFSHORE ALONG 140W (REMNANTS OF MARIE) AND
FORM A WEAK UPPER LEVEL TROUGH NEAR THE NORTHERN CA COAST BY
MIDWEEK. THIS TROUGH WILL THEN PERSIST THROUGH THE REMAINDER OF
THE WEEK AND PERHAPS INTO NEXT WEEKEND AS WELL. THERE DOES NOT
APPEAR TO BE SUFFICIENT MOISTURE WITH THE MARIE REMNANTS TO
PRODUCE ANY REAL CHANCE OF PRECIPITATION. HOWEVER...BY TUESDAY
NIGHT THERE MAY BE SUFFICIENT LOW LEVEL MOISTURE AND LIFT WITHIN A
MUCH DEEPER MARINE LAYER TO PRODUCE PATCHY DRIZZLE ALONG OUR
COAST...PARTICULARLY ALONG SOUTHWEST-FACING COASTAL TERRAIN AS LOW
LEVEL FLOW WILL BY THEN TAKE ON A SOUTHERLY COMPONENT. HAVE ADDED
VERY LOW POPS AND PATCHY DRIZZLE TO THE FORECAST FOR COASTAL AREAS
FOR LATE TUESDAY NIGHT/WEDNESDAY MORNING AND AGAIN WEDNESDAY
NIGHT/THURSDAY MORNING.

ALTHOUGH WEAK UPPER LEVEL TROUGHING IS EXPECTED TO CONTINUE ACROSS
NORTHERN CALIFORNIA THROUGH NEXT WEEKEND...THE UPPER TROUGH AXIS
IS FORECAST TO SHIFT INLAND WHICH SHOULD ALLOW FOR MODEST WARMING
BY FRIDAY OR SATURDAY.

(RH IN THE TEENS) SUPPORTING A CONTINUATION OF VFR AT ALL AREA

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
336 AM PDT MON SEP 1 2014

.SYNOPSIS...HIGH PRESSURE BUILDING ALONG THE CALIFORNIA COAST
WILL RESULT IN MOSTLY SUNNY SKIES AND WARM AFTERNOON TEMPERATURES
ON LABOR DAY. TEMPERATURES WILL THEN COOL ON TUESDAY AND WEDNESDAY
AS AN UPPER TROUGH DEVELOPS NEAR THE WEST COAST. DRY CONDITIONS
WILL PREVAIL EXCEPT FOR POSSIBLE PATCHY NIGHT AND MORNING DRIZZLE
IN COASTAL AREAS AROUND MIDWEEK.

&&

.DISCUSSION...AS OF 3:35 AM PDT MONDAY...UPPER LEVEL RIDGING OVER
SOUTHERN AND CENTRAL CALIFORNIA WILL PRODUCE WARM WEATHER
CONDITIONS ACROSS OUR REGION ON THIS LABOR DAY. THE FORT ORD
PROFILER SHOWS THAT THE MARINE LAYER HAS BEEN COMPRESSED TO A
DEPTH OF LESS THAN 500 FEET EARLY THIS MORNING AND SATELLITE
REVEALS ONLY PATCHY LOW CLOUDS...MAINLY NEAR MONTEREY BAY. ONSHORE
PRESSURE GRADIENTS HAVE DECREASED SINCE YESTERDAY MORNING AND SOME
LOCATIONS IN THE HILLS ARE EXPERIENCING LIGHT EASTERLY WINDS. ALL

WERE EITHER A FEW DEGREES COOLER OR THE SAME AS YESTERDAY`S HIGHS
WITH EXCEPTION OF REDWOOD CITY WHERE IT WAS TWO DEGREES WARMER
TODAY WITH A HIGH TEMPERATURE 88 F. MOST PLACES HAD HIGH AND LOW
TEMPERATURES A FEW DEGREES ABOVE THE NORMAL FOR THE LAST DAY OF
AUGUST. HARD TO BELIEVE... IT`S ALSO THE LAST DAY OF METEOROLOGICAL

ASSOCIATED WITH THE SHORTWAVE TROUGH COULD LEAD TO A FEW TRACES OF
VERY LIGHT STRATIFORM PRECIP...INCLUDING THE POSSIBILITY OF A FEW
CASES OF VERY LIGHT MEASURABLE RAINFALL ON THE COAST...BY MID-LATE
WEEK. THE 500 MB LEVEL COOLING IS A LITTLE MORE PRONOUNCED THURSDAY
AS COMPARED TO WEDNESDAY. THE TROUGH STALLS OVER THE FORECAST AREA
BY LATE IN THE WEEK AND POSSIBLY OVER THE WEEKEND AS WELL. THE MODELS

DRY WEATHER CONDITIONS.

&&

.DISCUSSION...AS OF 02:29 PM PDT SUNDAY...DESPITE CLEAR SKIES
ACROSS THE REGION THIS AFTERNOON...TEMPERATURES ARE GENERALLY A
FEW TO SEVERAL DEGREES COOLER THAN 24 HOURS AGO. IN LOOKING AT
THE FORT ORD PROFILER AND 12Z OAK SOUNDING...COOLER TEMPERATURES
ALOFT ARE THE CULPRIT OF THE COOL DOWN AT THE SURFACE. GIVEN A
MARINE LAYER AROUND 1000 FT OR SO...DO EXPECT AT LEAST
PATCHY/SCATTERED COASTAL CLOUDS TO DEVELOP OVERNIGHT AND PERSIST
THROUGH THE MID- MORNING HOURS ON LABOR DAY.

THE CENTER OF THE MID/UPPER LEVEL RIDGE JUST OFF THE SOUTHERN
CALIFORNIA COAST WILL BUILD FURTHER INTO THE SAN
FRANCISCO/MONTEREY BAY REGION TONIGHT THROUGH THE DAY ON MONDAY.
AS A RESULT...MOSTLY SUNNY SKIES WILL RETURN BY TOMORROW
AFTERNOON AND TEMPERATURES WILL REBOUND BACK TO SEVERAL DEGREES
ABOVE AVERAGE ACROSS INLAND AREAS.

THE NEXT MID/UPPER LEVEL TROUGH WILL DEVELOP ACROSS THE GULF OF
ALASKA AND DROP SOUTHWARD INTO THE PACIFIC NORTHWEST AND NORTHERN

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
407 PM PDT SUN AUG 31 2014

.SYNOPSIS...HIGH PRESSURE BUILDING ALONG THE CALIFORNIA COAST
WILL RESULT IN MOSTLY SUNNY SKIES AND WARM AFTERNOON TEMPERATURES
ON LABOR DAY. TEMPERATURES WILL THEN COOL SLIGHTLY TO NEAR
SEASONAL AVERAGES FOR THE REMAINDER OF THE WORK WEEK WITH ONGOING
DRY WEATHER CONDITIONS.

&&

.DISCUSSION...AS OF 02:29 PM PDT SUNDAY...DESPITE CLEAR SKIES
ACROSS THE REGION THIS AFTERNOON...TEMPERATURES ARE GENERALLY A
FEW TO SEVERAL DEGREES COOLER THAN 24 HOURS AGO. IN LOOKING AT
THE FORT ORD PROFILER AND 12Z OAK SOUNDING...COOLER TEMPERATURES
ALOFT ARE THE CULPRIT OF THE COOL DOWN AT THE SURFACE. GIVEN A
MARINE LAYER AROUND 1000 FT OR SO...DO EXPECT AT LEAST
PATCHY/SCATTERED COASTAL CLOUDS TO DEVELOP OVERNIGHT AND PERSIST
THROUGH THE MID- MORNING HOURS ON LABOR DAY.

THE CENTER OF THE MID/UPPER LEVEL RIDGE JUST OFF THE SOUTHERN
CALIFORNIA COAST WILL BUILD FURTHER INTO THE SAN
FRANCISCO/MONTEREY BAY REGION TONIGHT THROUGH THE DAY ON MONDAY.
AS A RESULT...MOSTLY SUNNY SKIES WILL RETURN BY TOMORROW
AFTERNOON AND TEMPERATURES WILL REBOUND BACK TO SEVERAL DEGREES
ABOVE AVERAGE ACROSS INLAND AREAS.

THE NEXT MID/UPPER LEVEL TROUGH WILL DEVELOP ACROSS THE GULF OF
ALASKA AND DROP SOUTHWARD INTO THE PACIFIC NORTHWEST AND NORTHERN
CALIFORNIA DURING THE EARLY PART OF THE WEEK. THIS WILL ALLOW
TEMPERATURES ALOFT TO COOL SLIGHTLY AND ONSHORE FLOW TO INCREASE.

&&

.DISCUSSION...AS OF 09:25 AM PDT SUNDAY...CLOUD COVER ACROSS THE
REGION THIS MORNING GENERALLY REMAINED PATCHY AND CONFINED TO
AREAS ALONG THE SAN MATEO COAST AND LOCATIONS ADJACENT TO THE
MONTEREY BAY. WILL CONTINUE TO SEE THE CLOUDS BURN-OFF THROUGH THE
MORNING HOURS WITH MOSTLY SUNNY SKIES REGION WIDE THIS AFTERNOON.
TEMPERATURES WILL ONCE AGAIN CLIMB TO ABOVE NORMAL VALUES FOR MOST
LOCATIONS WITH A DRY NORTHWEST FLOW ALOFT. MADE A FEW MINOR
UPDATES TO THE FORECAST TO REFLECT ONGOING TRENDS. OTHERWISE...THE
PREVIOUS FORECAST PACKAGE LOOKS TO BE IN GOOD SHAPE.

&&

.PREV DISCUSSION...AS OF 3:50 AM PDT SUNDAY...THE FORT ORD PROFILER
SHOWS THAT THE TEMPERATURE OF THE AIRMASS OVERLYING THE MARINE
INVERSION HAS COOLED ABOUT 4 DEG C SINCE YESTERDAY MORNING. THIS
HAS RESULTED IN A WEAKER MARINE INVERSION AND ONLY SCATTERED LOW
CLOUD DEVELOPMENT OVERNIGHT. WOULD EXPECT MOST LOCATIONS TO CLEAR
RELATIVELY EARLY TODAY GIVEN THE CURRENT DISORGANIZED STATE OF
THE MARINE LAYER. EVEN SO...EXPECT TEMPERATURES TO BE SLIGHTLY
COOLER TODAY COMPARED TO YESTERDAY GIVEN THE AIRMASS COOLING THAT
HAS TAKEN PLACE AND ALSO A SLIGHT INCREASE IN THE STRENGTH OF
ONSHORE FLOW.

AN UPPER LEVEL RIDGE CURRENTLY STRETCHED ACROSS THE EASTERN
PACIFIC ALONG 40 DEG N IS FORECAST TO STRENGTHEN ACROSS
CALIFORNIA TONIGHT AND MONDAY. AT THE SAME TIME...ONSHORE SURFACE
PRESSURE GRADIENTS ARE EXPECTED TO WEAKEN. THESE DEVELOPMENTS
WILL RESULT IN WARMER TEMPERATURES IN MOST AREAS ON LABOR
DAY...ALONG WITH MOSTLY SUNNY SKIES IN MOST AREAS BY AFTERNOON.
MONDAY WILL BE THE WARMEST DAY OF THE WEEK.

AN UPPER LEVEL TROUGH THAT WILL DEVELOP IN THE GULF OF ALASKA ON
MONDAY IS FORECAST TO DIG SOUTHEAST IN THE THE PAC NW AND FAR
NORTHERN CA BY LATE TUESDAY. THIS DEVELOPING TROUGH WILL TRIGGER
AN INCREASE IN ONSHORE FLOW BY TUESDAY AFTERNOON...AS WELL AS A
GENERAL AIRMASS COOLING ACROSS OUR AREA FROM TUESDAY INTO
THURSDAY. THE RESULT WILL BE MUCH COOLER TEMPERATURES INLAND BY
MIDWEEK. SOME OF THE WARMEST INLAND VALLEYS WILL COOL BY 10 TO 15
DEGREES FROM MONDAY INTO WEDNESDAY. COASTAL AREAS WILL SEE ONLY
MODEST COOLING...ESPECIALLY IF SEA SURFACE TEMPERATURES REMAIN
ABOUT 5 DEGREES WARMER THAN NORMAL. HOWEVER...GIVEN THE
PERSISTENT NORTHWEST WINDS FORECAST OVER THE COASTAL WATERS THE
NEXT FEW DAYS...AND ASSOCIATED INCREASE IN UPWELLING...FEEL IT`S
LIKELY THAT OUR COASTAL WATERS WILL TREND COOLER...DRAGGING
COASTAL AIR TEMPS LOWER TOO.

GRADUAL WARMING IS EXPECTED FROM FRIDAY INTO NEXT WEEKEND. THE
GFS AND GEM MODELS MAINTAIN A WEAK UPPER TROUGH OVER CALIFORNIA
RIGHT ON THROUGH NEXT WEEKEND...WHICH WOULD MEAN ONLY SLIGHT
WARMING LATE IN THE EXTENDED. THE ECMWF BEGINS TO BUILD AN UPPER
RIDGE NEAR THE WEST COAST BY NEXT WEEKEND...WHICH WOULD RESULT IN
MORE ROBUST WARMING DURING DAYS 6 AND 7. CURRENT FORECAST FAVORS
THE GFS/GEM SOLUTION.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
931 AM PDT SUN AUG 31 2014

.SYNOPSIS...DRY WEATHER CONDITIONS ALONG WITH ABOVE NORMAL
TEMPERATURES WILL CONTINUE THROUGH LABOR DAY. COOLER WEATHER IS
THEN FORECAST BEGINNING ON TUESDAY AND CONTINUING THROUGH THE END
OF THE WEEK.

&&

.DISCUSSION...AS OF 09:25 AM PDT SUNDAY...CLOUD COVER ACROSS THE
REGION THIS MORNING GENERALLY REMAINED PATCHY AND CONFINED TO
AREAS ALONG THE SAN MATEO COAST AND LOCATIONS ADJACENT TO THE
MONTEREY BAY. WILL CONTINUE TO SEE THE CLOUDS BURN-OFF THROUGH THE
MORNING HOURS WITH MOSTLY SUNNY SKIES REGION WIDE THIS AFTERNOON.
TEMPERATURES WILL ONCE AGAIN CLIMB TO ABOVE NORMAL VALUES FOR MOST
LOCATIONS WITH A DRY NORTHWEST FLOW ALOFT. MADE A FEW MINOR
UPDATES TO THE FORECAST TO REFLECT ONGOING TRENDS. OTHERWISE...THE
PREVIOUS FORECAST PACKAGE LOOKS TO BE IN GOOD SHAPE.

&&

.PREV DISCUSSION...AS OF 3:50 AM PDT SUNDAY...THE FORT ORD PROFILER
SHOWS THAT THE TEMPERATURE OF THE AIRMASS OVERLYING THE MARINE
INVERSION HAS COOLED ABOUT 4 DEG C SINCE YESTERDAY MORNING. THIS
HAS RESULTED IN A WEAKER MARINE INVERSION AND ONLY SCATTERED LOW
CLOUD DEVELOPMENT OVERNIGHT. WOULD EXPECT MOST LOCATIONS TO CLEAR
RELATIVELY EARLY TODAY GIVEN THE CURRENT DISORGANIZED STATE OF
THE MARINE LAYER. EVEN SO...EXPECT TEMPERATURES TO BE SLIGHTLY
COOLER TODAY COMPARED TO YESTERDAY GIVEN THE AIRMASS COOLING THAT
HAS TAKEN PLACE AND ALSO A SLIGHT INCREASE IN THE STRENGTH OF
ONSHORE FLOW.

AN UPPER LEVEL RIDGE CURRENTLY STRETCHED ACROSS THE EASTERN
PACIFIC ALONG 40 DEG N IS FORECAST TO STRENGTHEN ACROSS
CALIFORNIA TONIGHT AND MONDAY. AT THE SAME TIME...ONSHORE SURFACE
PRESSURE GRADIENTS ARE EXPECTED TO WEAKEN. THESE DEVELOPMENTS
WILL RESULT IN WARMER TEMPERATURES IN MOST AREAS ON LABOR
DAY...ALONG WITH MOSTLY SUNNY SKIES IN MOST AREAS BY AFTERNOON.
MONDAY WILL BE THE WARMEST DAY OF THE WEEK.

AN UPPER LEVEL TROUGH THAT WILL DEVELOP IN THE GULF OF ALASKA ON
MONDAY IS FORECAST TO DIG SOUTHEAST IN THE THE PAC NW AND FAR
NORTHERN CA BY LATE TUESDAY. THIS DEVELOPING TROUGH WILL TRIGGER
AN INCREASE IN ONSHORE FLOW BY TUESDAY AFTERNOON...AS WELL AS A
GENERAL AIRMASS COOLING ACROSS OUR AREA FROM TUESDAY INTO
THURSDAY. THE RESULT WILL BE MUCH COOLER TEMPERATURES INLAND BY
MIDWEEK. SOME OF THE WARMEST INLAND VALLEYS WILL COOL BY 10 TO 15
DEGREES FROM MONDAY INTO WEDNESDAY. COASTAL AREAS WILL SEE ONLY
MODEST COOLING...ESPECIALLY IF SEA SURFACE TEMPERATURES REMAIN
ABOUT 5 DEGREES WARMER THAN NORMAL. HOWEVER...GIVEN THE
PERSISTENT NORTHWEST WINDS FORECAST OVER THE COASTAL WATERS THE
NEXT FEW DAYS...AND ASSOCIATED INCREASE IN UPWELLING...FEEL IT`S
LIKELY THAT OUR COASTAL WATERS WILL TREND COOLER...DRAGGING
COASTAL AIR TEMPS LOWER TOO.

GRADUAL WARMING IS EXPECTED FROM FRIDAY INTO NEXT WEEKEND. THE
GFS AND GEM MODELS MAINTAIN A WEAK UPPER TROUGH OVER CALIFORNIA
RIGHT ON THROUGH NEXT WEEKEND...WHICH WOULD MEAN ONLY SLIGHT
WARMING LATE IN THE EXTENDED. THE ECMWF BEGINS TO BUILD AN UPPER
RIDGE NEAR THE WEST COAST BY NEXT WEEKEND...WHICH WOULD RESULT IN
MORE ROBUST WARMING DURING DAYS 6 AND 7. CURRENT FORECAST FAVORS
THE GFS/GEM SOLUTION.

&&

.AVIATION...AS OF 5:00 AM PDT SUNDAY...STRONG N-S GRADIENTS
LIMITING STRATUS TO THE COAST AND A SMALL PATCH IN THE EAST BAY.
THERE MAY BRING A BRIEF MVFR CIG TO OAK BUT SFO AND THE APPROACH
REMAINING VFR.

1028 AM PDT SAT AUG 30 2014

.SYNOPSIS...NORMAL TO SLIGHTLY ABOVE NORMAL TEMPERATURES AND DRY
WEATHER WILL PERSIST INTO THE FIRST HALF OF NEXT WEEK.

&&

.DISCUSSION...AS OF 09:03 AM PDT SATURDAY...PATCHY DENSE FOG WAS
OBSERVED THIS MORNING ACROSS THE MONTEREY BAY PENINSULA AND THE
NORTHERN SALINAS VALLEY. PER VISIBLE SATELLITE IMAGERY AND
REGIONAL WEB CAMS...THE FOG IS NOW CONFINED OVER THE MONTEREY BAY
AND UP ALONG HIGHWAY 1 TOWARDS MOSS LANDING. AS TEMPERATURES
CONTINUE TO WARM...THE FOG SHOULD DISSIPATE BY LATE MORNING.
ELSEWHERE...MOSTLY SUNNY SKIES ARE IN PLACE WITH FEW/SCT HIGH
CLOUDS STREAMING ACROSS THE REGION. THE ONGOING FORECAST LOOKS ON
TRACK AND ONLY MINOR CHANGES HAVE BEEN MADE TO REFLECT CURRENT
TRENDS.

&&

.PREV DISCUSSION...AS OF 3:10 AM PDT SATURDAY...CLOUDS FROM FORMER
HURRICANE MARIE PROVIDED SOME BEAUTIFUL SUNSET SHOTS LAST NIGHT AND
ARE CONTINUING TO KEEP HIGHER LEVEL CLOUDS STREAMING ACROSS OUR
CWA. SATELLITE FOG PRODUCT SHOWS AT THIS TIME VIRTUALLY NO FOG
FORMATION ACROSS OUR ENTIRE AREA, SO HAVE ISSUED A MINOR FORECAST
UPDATE TO REMOVE IT FROM ALMOST ALL SPOTS AWAY FROM THE COAST.
SUNNY SKIES ARE FORECAST BY LATE IN THE MORNING WITH TEMPS VERY
CLOSE TO FRIDAY -- MID 60S TO UPPER 70S AT THE COAST WITH UPPER
70S TO LOWER 90S FOR MOST INLAND SPOTS. LOCALLY BREEZY CONDITIONS
ARE LIKELY THIS AFTERNOON AND EARLY IN THE EVENING AS SURFACE
GRADIENTS INCREASE (SFO-TONOPAH GOES OVER 6 MB).

QUIET WEATHER IS EXPECTED FOR SUNDAY AND LABOR DAY AS A RIDGE OF
HIGH PRESSURE OUT IN THE PACIFIC BUILDS TO CALIFORNIA AS A
LONGWAVE TROF TO OUR EAST PROGRESSES INTO THE CENTRAL CONUS. BOTH
DAYS WILL FEATURE TEMPERATES CLOSE TO WHAT WE WILL SEE TODAY WITH
A FEW DEGREES OF COOLING INLAND AS 850 MB TEMPS COOL 1-2C. LOOKS
LIKE NEARLY PERFECT WEATHER FOR OUTDOOR ACTIVITIES.

QUIET WEATHER IS FORECAST FOR THE REMAINDER OF NEXT WEEK WITH THE
MAIN STORM TRACK WELL TO OUR NORTH. MODELS DO BRING WHAT IS LEFT
OF HURRICANE MARIE OVER TO OUR CWA, HOWEVER CURRENTLY VERY GOOD
AGREEMENT THAT ALL IT WILL LIKELY PRODUCE IS JUST HIGH CLOUDS.

SUNNY SKIES ARE FORECAST BY LATE IN THE MORNING WITH TEMPS VERY
CLOSE TO FRIDAY -- MID 60S TO UPPER 70S AT THE COAST WITH UPPER
70S TO LOWER 90S FOR MOST INLAND SPOTS. LOCALLY BREEZY CONDITIONS
ARE LIKELY THIS AFTERNOON AND EARLY IN THE EVENING AS SURFACE
GRADIENTS INCREASE (SFO-TONAPAH GOES OVER 6 MB).

QUIET WEATHER IS EXPECTED FOR SUNDAY AND LABOR DAY AS A RIDGE OF
HIGH PRESSURE OUT IN THE PACIFIC BUILDS TO CALIFORNIA AS A
LONGWAVE TROF TO OUR EAST PROGRESSES INTO THE CENTRAL CONUS. BOTH
DAYS WILL FEATURE TEMPERATES CLOSE TO WHAT WE WILL SEE TODAY WITH
A FEW DEGREES OF COOLING INLAND AS 850 MB TEMPS COOL 1-2C. LOOKS
LIKE NEARLY PERFECT WEATHER FOR OUTDOOR ACTIVITIES.

QUIET WEATHER IS FORECAST FOR THE REMAINDER OF NEXT WEEK WITH THE
MAIN STORM TRACK WELL TO OUR NORTH. MODELS DO BRING WHAT IS LEFT
OF HURRICANE MARIE OVER TO OUR CWA, HOWEVER CURRENTLY VERY GOOD
AGREEMENT THAT ALL IT WILL LIKELY PRODUCE IS JUST HIGH CLOUDS.
KEPT POPS NEAR ZERO FOR ALL DAYS.
&&

.AVIATION...AS OF 10:45 PM PDT FRIDAY...MID AND HIGH CLOUDS ARE
OBSCURING THE COASTAL STRATUS COVERAGE AT THE MOMENT. MODEL FORECASTS
INDICATE ADDITIONAL STRATUS REDEVELOPMENT OVERNIGHT BUT THERE IS ALSO
AN APPRECIABLY DRIER LAYER DEVELOPING JUST ABOVE THE MARINE INVERSION.
THIS DRIER LAYER SHOULD HELP MIX OUT THE STRATUS CLOUDS FAIRLY
QUICKLY SATURDAY MORNING.

VICINITY OF KSFO...VFR HAS BEEN HOLDING THROUGH THE EVENING SO
FAR. TAF INDICATES BKN CIG BY 07Z WHICH MAY BE A BIT EARLY BUT
CONFIDENCE IN FORECAST LOWER TONIGHT DUE TO OBSCURED LOWER CLOUD
FIELD. MODERATE TO HIGH CONFIDENCE VFR FORECAST FOR SATURDAY.

KSFO BRIDGE APPROACH...SIMILAR TO KSFO.

MONTEREY BAY AREA TERMINALS...THERE HAS BEEN SCT-BKN CLOUD COVER
SO FAR THIS EVENING. IFR IS FORECAST TONIGHT. THE STRATUS CLOUDS
SHOULD MIX OUT BY LATE SATURDAY MORNING.

.SYNOPSIS...NORMAL TO SLIGHTLY ABOVE NORMAL TEMPERATURES AND DRY
WEATHER WILL PERSIST THROUGH THE HOLIDAY WEEKEND.

&&

.DISCUSSION...AS OF 9:25 PM PDT FRIDAY...MIDDLE AND HIGH LEVEL
CLOUDS CONTINUE TO SHEAR EASTWARD FROM THE REMNANTS OF TROPICAL
CYCLONE "MARIE" AS THE ENTIRE SYSTEM MOVES HIGHER IN LATITUDE. THE
00Z OAKLAND SOUNDING SHOWED THE TOTAL PRECIPITABLE WATER VALUE
ALSO INCREASING TO 0.98" THIS EVENING UP FROM 0.70" 24 HOURS AGO.
ALL THE EXTRA CLOUDS IN THE SKY TODAY MADE FOR PICTURESQUE
CONDITIONS AND A DECENT FINALE WITH A COLORFUL SKY RIGHT AT
SUNSET.

AS THE REMNANTS OF"MARIE" CONTINUE TO MEANDER NORTH IN LATITUDE
THE MID-UPPER LEVEL CIRCULATION CENTER WILL DETACH AND MOVE WITH
THE MID-LAT WESTERLIES THEN MERGE WITH A SHORTWAVE TROUGH FROM THE
HIGHER LATITUDES. THE NEWLY MERGED SYSTEM WILL PASS OVER NORTHERN
CALIFORNIA NEXT WEDNESDAY INTO THURSDAY. THE SURFACE TO LOW LEVEL
CIRCULATION WILL MEANDER AND DIMINISH OVER THE PACIFIC SENDING
HIGHER TPW AIR NORTH IN LATITUDE EVENTUALLY NORTH OVER THE EPAC
RIDGE WITH SOME OF THIS MORE HUMID AIR POSSIBLY RETURNING
SOUTHEAST OVER THE OFFSHORE WATERS BY LATE NEXT WEEK OR WEEKEND.

LIGHT QPF...A FEW HUNDREDTHS HERE AND THERE...OVER THE FORECAST
AREA FROM WED-THU FITTING THE TIME FRAME WHEN THE AFOREMENTIONED
MID-UPPER LEVEL CIRCULATION PASSES OVER NORCAL. THE MODELS SHOW IT

SCENARIO AS THE MODELS DO NOT SHOW VERY MUCH HUMIDITY BELOW 500 MB
ON THE CROSS-SECTIONS THEREFORE CHANCES FOR MID LEVEL CONVECTION
APPEAR TO BE NEAR ZERO PERCENT. IT`S NOT IN OUR FORECASTS
CURRENTLY BUT IF SUBSEQUNET MODEL RUNS SHOW VERY LIGHT QPF IN
SIMILAR WED-THU TIMEFRAME...WE MAY NEED TO THINK ABOUT ADDING LOW
END CHANCE POPS FOR THE MIDDLE-LATER PART OF NEXT WEEK.

.SYNOPSIS...NORMAL TO SLIGHTLY ABOVE NORMAL TEMPERATURES AND DRY
WEATHER WILL PERSIST THROUGH THE HOLIDAY WEEKEND.

&&

.DISCUSSION...AS OF 01:58 PM PDT FRIDAY...
SATELLITE SHOWS MID AND HIGH LEVEL CLOUDS CONTINUING TO STREAM
ACROSS THE AREA FROM WHAT REMAINS OF MARIE IN THE PACIFIC. LOW
CLOUDS APPEAR TO HAVE MELTED BACK OFF THE COAST AT THIS POINT MOST
LOCATIONS. THE AREA STARTS THE FORECAST PERIOD TODAY ON THE 500 MB
LEVEL WITH A RIDGE OVER SOUTHERN CALIFORNIA AND A TROUGH PUSHING
INTO THE PACIFIC NORTHWEST. THE EVOLUTION OF THOSE FEATURES OVER
THE NEXT FEW DAYS WILL BE FOR THE RIDGE TO BE SUPPRESSED SOUTH AND
HEIGHTS WILL FALL OVER THE FORECAST AREA AS THE PACIFIC TROUGH
MOVES ONSHORE. BY LATER ON MONDAY THE TROUGH WILL BE OUT OF THE
AREA AND ALLOW THE SOUTHERN RIDGE TO BUILD ONCE AGAIN AND BECOME A
MORE DOMINANT FEATURE GOING THROUGH THE COMING WEEK...UNTIL AN
APPROACHING TROUGH BRINGS A DECREASE IN HEIGHT FIELDS IN THE AREA
BY THURSDAY. FOR THE DETAILS...THE MID AND HIGH CLOUDS TODAY WHICH
ARE MARKED BY INCREASED RH IN THE 200-400 MB LEVEL...WILL DRIFT
ACROSS THE AREA THROUGH TONIGHT AND THEN BY SATURDAY WILL BE
PUSHED INTO THE SOUTHERN THIRD OF THE FORECAST AREA AND THEN THE
MOISTURE EXITS THE AREA BY SATURDAY AFTERNOON. TEMPERATURES DURING
THE FORECAST PERIOD WILL WARM TO NEAR AND ABOVE NORMAL BY EARLY
THIS COMING WEEK AS THE RIDGE OF MID LEVEL HIGH PRESSURE BUILDS
IN. THIS WILL PERSIST UNTIL LATE WEEK WHEN THE TROUGH APPROACHES
AND LOOKS TO BRING A COOLING TREND...ESPECIALLY ACROSS THE
INTERIOR AREAS. NO RAIN EXPECTED THROUGH THE 7 DAY FORECAST
PERIOD. THE EXCEPTION WOULD BE COASTAL DRIZZLE ESPECIALLY LATE
NEXT WEEK WITH A TROUGH DEEPENING TO OUR WEST.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
535 PM PDT FRI AUG 29 2014

.SYNOPSIS...NORMAL TO SLIGHTLY ABOVE NORMAL TEMPERATURES AND DRY
WEATHER WILL PERSIST THROUGH THE HOLIDAY WEEKEND.

&&

.DISCUSSION...AS OF 01:58 PM PDT FRIDAY...
SATELLITE SHOWS MID AND HIGH LEVEL CLOUDS CONTINUING TO STREAM
ACROSS THE AREA FROM WHAT REMAINS OF MARIE IN THE PACIFIC. LOW
CLOUDS APPEAR TO HAVE MELTED BACK OFF THE COAST AT THIS POINT MOST
LOCATIONS. THE AREA STARTS THE FORECAST PERIOD TODAY ON THE 500 MB
LEVEL WITH A RIDGE OVER SOUTHERN CALIFORNIA AND A TROUGH PUSHING
INTO THE PACIFIC NORTHWEST. THE EVOLUTION OF THOSE FEATURES OVER
THE NEXT FEW DAYS WILL BE FOR THE RIDGE TO BE SUPPRESSED SOUTH AND
HEIGHTS WILL FALL OVER THE FORECAST AREA AS THE PACIFIC TROUGH
MOVES ONSHORE. BY LATER ON MONDAY THE TROUGH WILL BE OUT OF THE
AREA AND ALLOW THE SOUTHERN RIDGE TO BUILD ONCE AGAIN AND BECOME A
MORE DOMINANT FEATURE GOING THROUGH THE COMING WEEK...UNTIL AN
APPROACHING TROUGH BRINGS A DECREASE IN HEIGHT FIELDS IN THE AREA
BY THURSDAY. FOR THE DETAILS...THE MID AND HIGH CLOUDS TODAY WHICH
ARE MARKED BY INCREASED RH IN THE 200-400 MB LEVEL...WILL DRIFT
ACROSS THE AREA THROUGH TONIGHT AND THEN BY SATURDAY WILL BE
PUSHED INTO THE SOUTHERN THIRD OF THE FORECAST AREA AND THEN THE
MOISTURE EXITS THE AREA BY SATURDAY AFTERNOON. TEMPERATURES DURING
THE FORECAST PERIOD WILL WARM TO NEAR AND ABOVE NORMAL BY EARLY
THIS COMING WEEK AS THE RIDGE OF MID LEVEL HIGH PRESSURE BUILDS
IN. THIS WILL PERSIST UNTIL LATE WEEK WHEN THE TROUGH APPROACHES
AND LOOKS TO BRING A COOLING TREND...ESPECIALLY ACROSS THE
INTERIOR AREAS. NO RAIN EXPECTED THROUGH THE 7 DAY FORECAST
PERIOD. THE EXCEPTION WOULD BE COASTAL DRIZZLE ESPECIALLY LATE
NEXT WEEK WITH A TROUGH DEEPENING TO OUR WEST.

&&

.AVIATION...AS OF 5:30 PM PDT FRIDAY...THERE`S A COMBINATION OF STRATUS
CLOUDS AS WELL AS MID AND HIGH LEVEL CLOUDS OVER THE AREA. THE MID/HIGH
CLOUDS ARE FROM THE REMNANTS OF "MARIE." ASIDE FROM THE STRATUS CLOUDS
FILTERING EASTWARD THROUGH THE GOLDEN GATE AND OVER THE BAY WATERS MOST
OF THE STRATUS CLOUDS ARE CONFINED TO THE IMMEDIATE COAST. THE MARINE
LAYER IS SOMEWHAT COMPRESSED HOLDING BETWEEN 1200-1300 FEET DEEP. LOW
LEVEL TEMPS ARE FORECAST TO EVER SO SLIGHTLY COOL OFF THROUGH THE
WEEKEND BUT IT`S NOT LOOKING LIKE IT`S ENOUGH COOLING TO MIX OUT THE
MARINE LAYER INVERSION...AT LEAST NOT INTO SATURDAY. THE NAM MODEL
SHOWS LOWER HUMIDITY (RH IN THE TEENS) DEVELOPING IN THE LOWER LEVELS
OF THE ATMOSPHERE OVER THE BAY AREA AND CENTRAL COAST TONIGHT
THROUGH SATURDAY WHICH SHOULD HELP WITH EARLY MIXING OUT OF THE
STRATUS CLOUDS SATURDAY MORNING. ADDITIONALLY THE NAM MODEL FORECASTS
A STEADILY INCREASING SURFACE PRESS GRADIENT ACV-SFO REACHING UPWARDS
OF 6-7 MB OVER THE WEEKEND. INCREASING NW WINDS...MIXING...AND DECREASING
HUMIDITY WITHIN THE BOUNDARY LAYER SATURDAY SHOULD LIMIT COASTAL STRATUS
COVERAGE BY THIS TIME TOMORROW. THE INCREASING NORTH-SOUTH GRADIENT
SHOULD ALSO LIMIT INLAND STRATUS MOTION SAT EVENING VERY LIKELY
PROLONGING VFR AT THE BAY AREA TERMINALS THIS TIME TOMORROW EVENING.

VICINITY OF KSFO...MODERATE TO HIGH CONFIDENCE VFR HOLDS FOR THE
EVENING GIVEN A MARINE LAYER INVERSION NEAR 1300 FEET DEEP PER SAN
CARLOS SODAR. ON THE FLIP SIDE A COMPRESSED INVERSION OFTEN SUPPORTS
GUSTY EVENING WINDS THROUGH THE SAN BRUNO GAP WHEN ONSHORE GRADIENTS
ARE MOD OR STRONG...HOWEVER THE HALF MOON BAY BUOY-SFO GRADIENT HAS
SUBSIDED TO LESS THAN 1 MB WHICH IS WEAK AND SHOULD HELP HOLD WEST
WINDS DOWN THROUGH THE EVENING.

KSFO BRIDGE APPROACH...SIMILAR TO KSFO.

MONTEREY BAY AREA TERMINALS...THE ONSHORE WINDS WILL BRING IN IFR
CEILINGS EARLY THIS EVENING. IFR IS FORECAST TONIGHT. THE STRATUS
CLOUDS SHOULD MIX OUT BY LATE SAT MORNING.

&&

.MARINE...AS OF 2:50 PM PDT FRIDAY...HIGH PRESSURE WILL BUILD OFF
THE NORTHERN CALIFORNIA COAST RESULTING IN INCREASING NORTHWEST
WINDS THAT WILL LAST THROUGH EARLY NEXT WEEK. RESIDUAL SOUTHERLY
SWELL FROM HURRICANE MARIE WILL CONTINUE TO DIMINISH.

&&
