AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
1059 AM PDT FRI OCT 10 2014

.SYNOPSIS...SLIGHTLY COOLER WEATHER IS FORECAST TODAY. A BRIEF
WARMING TREND IS THEN EXPECTED OVER THE WEEKEND AS AN UPPER LEVEL
RIDGE BUILDS NEAR THE WEST COAST. A CHANGE IN THE WEATHER PATTERN
EARLY NEXT WEEK WILL RESULT IN MUCH COOLER WEATHER BY MIDWEEK...ALONG
WITH A CHANCE OF PRECIPITATION. A LARGE NORTHWEST SWELL IS
EXPECTED TO IMPACT THE COAST BEGINNING SATURDAY.

&&

.DISCUSSION...AS OF 8:30 AM PDT FRIDAY...EXTENSIVE CLOUD COVER
THIS MORNING EXTENDING FROM THE COAST INTO MOST LOWER ELEVATION
INTERIOR SPOTS. AGREE WITH THE PREVIOUS SHIFT THAT THE INCREASE IN
CLOUDS SHOULD LEAD TO A FEW DEGREES OF COOLING FOR MOST SPOTS.

MAIN FORECAST HIGHLIGHTS CALL FOR WARMER WEATHER ALONG WITH
ELEVATED FIRE WEATHER CONCERNS THIS WEEKEND AS AN OFFSHORE FLOW
KICKS IN, PLUS RAIN RETURNING BY THE MIDDLE OF THE WEEK. CURRENT
FORECAST GENERALLY APPEARS TO BE ON TRACK, SO ONLY MINOR UPDATES
ARE ANTICIPATED.

.PREVIOUS DISCUSSION...A DEEPER MARINE LAYER AND STRONGER ONSHORE
FLOW WILL RESULT IN COOLER TEMPERATURES TODAY ACROSS THE DISTRICT.
EARLY MORNING TEMPERATURE TRENDS ARE ALREADY RUNNING COOLER THAN
YESTERDAY AT THIS TIME BY SEVERAL DEGREES. SATELLITE IMAGERY SHOWS
THAT LOW CLOUDS HAVE EXTENDED FARTHER INLAND THIS MORNING COMPARED
TO 24 HOURS AGO AND NOW COVER MOST OF THE SAN FRANCISCO BAY....THE
NORTH BAY VALLEYS AND THE SALINAS VALLEY. MORE CLOUD COVER AND
SLOWER BURN-OFF TIMES WILL ALSO CONTRIBUTE TO COOLER TEMPS TODAY.
HIGHS TODAY ARE EXPECTED TO RANGE FROM THE 60S AT THE COAST TO THE
70S AND 80S INLAND. THE WARMEST INLAND AREAS ARE ONLY EXPECTED TO
BE AROUND 90 TODAY.

A BRIEF WARMING TREND IS ON TAP FOR THE WEEKEND AS AN UPPER RIDGE
BUILDS JUST OFFSHORE. A SURFACE HIGH IS FORECAST TO BUILD INTO THE
PACIFIC NORTHWEST AND THEN INTO THE GREAT BASIN TIGHTENING THE
SURFACE PRESSURE GRADIENT ACROSS NORTHERN CALIFORNIA. THIS WILL
INCREASE THE OFFSHORE FLOW BY LATE SATURDAY NIGHT AND SUNDAY
MORNING. NEAR-COASTAL TEMPERATURES WILL BE MUCH WARMER ON SUNDAY
WITH HIGHS APPROACHING 80. NORTH WINDS ON SATURDAY NIGHT AND
SUNDAY WILL LIKELY BE STRONGEST IN THE HIGHER TERRAIN...ESPECIALLY
THE NORTH AND EAST BAY HILLS. THIS WILL RESULT IN HEIGHTENED FIRE
WEATHER CONCERNS FROM LATE SATURDAY NIGHT THROUGH SUNDAY NIGHT. A
FIRE WEATHER WATCH IS IN EFFECT FOR THE NORTH AND EAST BAY HILLS
ABOVE 1000 FEET FROM 11 PM PDT SATURDAY NIGHT THROUGH 3 AM PDT
EARLY MONDAY MORNING. THE AREA OF GUSTY WINDS COULD EXTEND SOUTH
TO INCLUDE THE SANTA CRUZ MOUNTAINS AS WELL.

THE UPPER RIDGE IS PROGGED TO MOVE QUICKLY EASTWARD ON MONDAY WITH
ONSHORE FLOW DEVELOPING BY AFTERNOON. COASTAL AREAS SHOULD SEE
SOME COOLING ON MONDAY...BUT INLAND AREAS WILL STILL BE WARM. COOLER
TEMPERATURES AND UNSETTLED WEATHER IS THEN EXPECTED FOR THE REST
OF NEXT WEEK AS AN UPPER TROUGH ORIGINATING IN THE GULF OF ALASKA
DIGS SOUTH ALONG THE WEST COAST. AN ASSOCIATED COLD FRONT MAY
SPREAD RAIN AS FAR SOUTH AS SAN FRANCISCO BY TUESDAY AFTERNOON.
THE MEDIUM RANGE MODEL SOLUTIONS ARE IN DECENT AGREEMENT THROUGH
TUESDAY BUT DO BEGIN TO DIFFER FROM MIDWEEK ON. THE GEM IS THE
MOST BULLISH WITH RAINY CONDITIONS THROUGH THE REST OF THE WEEK
WHILE THE ECMWF AND GFS KEEP MOST OF THE DISTRICT DRY FROM
WEDNESDAY THROUGH LATE FRIDAY. THUS...LOW CONFIDENCE CONTINUES IN
THE FORECAST FROM THE MIDDLE OF NEXT WEEK ONWARD.

&&

.AVIATION...AS OF 10:50 AM PDT FRIDAY...THE MARINE LAYER HAS
DEEPENED TO AROUND 2000 FT THIS MORNING AND WITH AN INCREASINGLY
LOWER SUN ANGLE THE WIDESPREAD STRATUS IS SLOWER TO BURN OFF.
LIGHT TO MODERATE SEA BREEZE THIS AFTERNOON.

VICINITY OF KSFO...STRATUS BURN OFF IS PROGRESSING NORTH UP THE
PENINSULA AND THE TERMINAL IS EXPECTED TO CLEAR AROUND 19Z.
SEABREEZE TO AROUND 15 KT THIS AFTERNOON. STRATUS TO RETURN LATE
EVENING.

KSFO BRIDGE APPROACH...STRATUS IS CLEARING UP THE PENINSULA SO
APPROACH SHOULD BE CLEAR BY THE TIME TERMINAL CLEARS THOUGH A FEW
STRAY CLOUDS ARE NOT OUT OF THE QUESTION FOR A SHORT PERIOD AFTER.

MONTEREY BAY AREA TERMINALS...SNS TO BURN OFF SHORTLY HOWEVER MRY
LOOKS TO HAVE A CIG AT LEAST INTO THE AFTERNOON. CIGS TO RETURN BY
LATE AFTERNOON TO EARLY EVENING.

&&

.FIRE WEATHER...AS OF 3:00 AM PDT FRIDAY...NO SIGNIFICANT FIRE
WEATHER CONCERNS THROUGH SATURDAY AFTERNOON. HOWEVER A FIRE
WEATHER WATCH HAS BEEN POSTED FOR LATER SATURDAY NIGHT THROUGH
EARLY MONDAY MORNING WHEN A FAVORABLE OFFSHORE WIND PATTERN LOOKS
TO BE SETTING UP. A STRONG HIGH CENTERED OVER THE EASTERN PACIFIC
WILL BEGIN TO EXTEND OVER CALIFORNIA WHILE ENERGY WILL DROP INTO
NEVADA...RESULTING IN A STRONG SURFACE PRESSURE GRADIENT FROM THE
GREAT BASIN TOWARDS THE COAST. UNLIKE OTHER EVENTS THERE IS GOOD
DYNAMIC FORCING WITH NEGATIVE VORTICITY ADVECTION ALOFT AND
DOWNWARD MOTION FROM 500-700 MB. THE FLOW ALOFT IS NORTHERLY AT
700 MB WITH STRONG WINDS AS WELL. SO EVEN THOUGH THERE IS NOT
STRONG COLD ADVECTION THE AIR ALOFT SHOULD BE ABLE TO MIX DOWN TO
THE RIDGES. GIVEN ALL THIS STILL BELIEVE THAT MODEL SOLUTION WINDS
ARE NOT STRONG ENOUGH.

EXPECT NORTH WINDS TO HOWL DOWN THE SAC VALLEY SATURDAY EVENING THEN
BEGIN TO IMPACT THE NAPA HILLS BY LATER SATURDAY NIGHT INTO THE
PRE-DAWN HOURS OF SUNDAY. HUMIDITY VALUES WILL INITIALLY BE FAIRLY
MOIST BUT SHOULD DRY OUT OVERNIGHT. SOME CONCERN OVER DROUGHT AND
DISEASE STRESSED TREES WITH WINDS STRONG ENOUGH TO BRING DOWN
POWER LINES AND SMALL BRANCHES IN WIND PRONE SPOTS OF NAPA AND DELTA
REGION. IN ADDITION GIVEN THE STRONG WINDS ALOFT ANY NEW STARTS WILL
SEE RAPID GROWTH. NORTH WINDS WILL REACH THE EAST BAY HILLS A FEW
HOURS LATER BUT SHOULD BE CRANKING BY SUNRISE SUNDAY...ESPECIALLY
AROUND MT DIABLO AND THE HILLS ABOVE 1500-2000 FEET. THE PERIOD OF
STRONGEST WINDS LOOKS TO BE FROM SUNRISE SUNDAY THROUGH ABOUT LUNCH
TIME WHEN ALL OF THE MODELS KEEP SHOWING SOLID SURFACE PRESSURE
GRADIENTS AND DYNAMICAL SUPPORT FOR WIDESPREAD WIND GUSTS FROM 30-40
MPH. WINDS WILL EASE THROUGH THE AFTERNOON...BUT THEN VERY DRY AIR
WILL SETTLE OVER THE REGION WITH RH READINGS FROM 8-18%. POOR
HUMIDITY RECOVERY SUNDAY NIGHT (ESSENTIALLY NONE) WITH CONTINUED
OFFSHORE FLOW IS REASONING FOR KEEPING THE WATCH THROUGH SUNDAY
NIGHT. GOOD NEWS IS ONSHORE WINDS RETURN MONDAY WITH EVEN A CHANCE
OF NORTH BAY SHOWERS BY TUESDAY. KEEP IN MIND CLIMATOLOGY FAVORS
OCTOBER WEATHER CHANGES SUCH AS THIS FOR OUR LARGE FIRE GROWTH DAYS
IN THE BAY AREA. LONG TERM DROUGHT STRESS CONTINUES ON THE LARGE
FUELS WITH EARLIER RAIN IMPACTS NOW NULLIFIED. DECISION TO UPGRADE
TO RED FLAG WARNING WILL BE MADE TOMORROW AS WE GET WITH 24-36 HOURS
OF EVENT. CONFIDENCE IS MEDIUM TO HIGH.

&&

.MARINE...AS OF 2:47 AM PDT FRIDAY...A THERMAL TROUGH POSITIONED
OVER CALIFORNIA WILL MAINTAIN MODERATE WINDS ACROSS THE OUTER
COASTAL WATERS THROUGH THE WEEKEND. MODERATE WINDS WILL ALSO BE
POSSIBLE ALONG THE INNER COASTAL WATERS BUT WILL BE PRIMARILY
SOUTH OF COASTAL POINTS. A SMALL LONG PERIOD NORTHWEST SWELL WILL
MOVE THROUGH THE WATERS TODAY. A MUCH LARGER LONG PERIOD NORTHWEST
SWELL IS EXPECTED TO REACH THE COAST SATURDAY MORNING PERSISTING
THROUGH LATE SUNDAY NIGHT. THESE LONG PERIOD WAVES WILL RESULT IN
LARGE BREAKERS ALONG THE COAST.
