AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
848 AM PDT WED SEP 25 2013

.DISCUSSION...AS OF 8:48 AM PDT WEDNESDAY...THE CURRENT SATELLITE
WATER VAPOUR IMAGE IS SHOWING A TROUGH OF LOW PRESSURE CENTERED
OVER THE PACIFIC NORTHWEST. COOL AIR ASSOCIATED WITH THIS TROUGH
IS SETTLING IN OVER THE FORECAST AREA WITH LOCAL OBSERVATIONS
REPORTING TEMPERATURES AVERAGING 5 DEGREES COOLER THAN AT THIS
HOUR YESTERDAY.

THE 0000Z ECMWF AND 0600Z GFS40 HAVE BOTH INITIALIZED WELL WITH THE
PREVIOUSLY MENTIONED TROUGH OF LOW PRESSURE. THEY ARE ALSO IN GOOD
AGREEMENT WITH SLIDING THE CENTER OF THE LOW TOWARDS THE GREAT
BASIN OVERNIGHT. AS THE LOW SLIDES EAST THE SURFACE PRESSURE
GRADIENT WILL BECOME OFFSHORE...RESULTING IN EAST TO NORTHEAST
WINDS THURSDAY AND FRIDAY. THE OFFSHORE WINDS WILL TRANSLATE INTO
WARM DRY CONDITIONS ACROSS THE FORECAST AREA. FIRE CONCERNS WILL
RISE UNDER THE OFFSHORE SCENARIO...FOR MORE INFORMATION ON THESE
CONCERNS PLEASE SEE THE FIRE WEATHER DISCUSSION.

LIGHT ONSHORE FLOW WILL RETURN TO THE FORECAST AREA SATURDAY AS
THE AFORE MENTIONED LOW CONTINUES TO TREK EAST. ZONAL FLOW WILL
BUILD ALOFT SATURDAY AND SUNDAY...MAINTAINING DRY MILD TO WARM
CONDITIONS. MODEL AGREEMENT BEGINS TO BREAK DOWN SUNDAY WITH BOTH
THE ECMWF AND GFS SLIDING A FRONT INTO THE PACIFIC NORTHWEST AND
NORTHERN CALIFORNIA. THE 0000Z ECMWF AND THE 0600Z GFS40 BOTH
SUGGEST LIGHT PRECIPITATION OVER THE NORTH BAY SUNDAY AND MONDAY.
THE GFS ENSEMBLE MEMBERS ALSO INDICATE A POTENTIAL FOR
PRECIPITATION. HOWEVER...THE 500MB HEIGHTS ARE FAIRLY HIGH...580
DM... AND CLIMATOLOGY DOES NOT SUPPORT PRECIPITATION AT THIS TIME.
THEREFORE...WILL CONTINUE TO MONITOR GUIDANCE AND UPDATE AS NEEDED.

PREVIOUS DISCUSSION... IF THE MEDIUM RANGE MODELS ARE
CORRECT...ANOTHER OFFSHORE WIND EVENT WOULD OCCUR DURING THE
MIDDLE PART OF NEXT WEEK...WITH SOMEWHAT STRONGER OFFSHORE WINDS
THAN THOSE ANTICIPATED DURING THIS WEEK'S OFFSHORE WIND EVENT.

&&

.AVIATION...AS OF 4:15 AM PDT WEDNESDAY...ANOTHER DRY MORNING
AROUND THE BAY AREA AS CLEAR SKIES PREVAIL. A FEW HIGH LEVEL
CLOUDS WILL BE POSSIBLE WITH VFR CONDITIONS. THE WEATHER ITEM OF
NOTE WILL BE THE GUSTY WINDS AGAIN TODAY. NOT EXPECTING AIRPORT
WEATHER WARNING(AWW) CRITERIA THIS AFTERNOON...BUT WOULD NOT BE
SURPRISED IF WINDS APPROACH 35 KT BRIEFLY. MODERATE TO HIGH
CONFIDENCE.

VICINITY OF KSFO...VFR CONDITIONS THROUGH THE PERIOD. WEST WINDS
POSSIBLE THIS AFTERNOON 20-25 KT WITH A GUST OR TWO OVER 30 KT.
CONF IS NOT HIGH ENOUGH FOR AWW. MODERATE TO HIGH CONFIDENCE.

KSFO BRIDGE APPROACH...SIMILAR TO KSFO.

MONTEREY BAY AREA TERMINALS...VFR CONDITIONS THROUGH THE PERIOD.
GUSTY WEST WINDS POSSIBLE AGAIN THIS AFTERNOON WITH GUSTS IN THE
20-25 KT RANGE. MODERATE TO HIGH CONFIDENCE.

&&

.FIRE WEATHER...AS OF 3:50 AM WEDNESDAY...EVEN WITH RAINFALL THIS
PAST WEEKEND...OVERALL FUELS REMAIN DRY AND FUELS WILL DRY FURTHER
THROUGH THE END OF THE WEEK AS GUSTY WINDS CONTINUE AND RELATIVE
HUMIDITY LEVELS DROP. UPPER LEVEL PATTERN SUPPORTS A RELATIVELY
STRONG NORTHERLY WIND EVENT BEGINNING LATE TONIGHT IN THE NORTH
AND EAST BAY HILLS. EVEN THOUGH THE AIRMASS WILL INITIALLY BE
RATHER COOL AND MOIST TONIGHT...THIS TYPE OF PATTERN IS ONE THAT
CAN PRODUCE DOWNED TREES AND POWER LINES. HUMIDITY VALUES WILL
BEGIN TO FALL IN THE HILLS LATE TONIGHT AND THEN DROP QUICKLY
AFTER SUNRISE ON THURSDAY.

WINDS WILL EASE SOMEWHAT ON THURSDAY AFTERNOON AND EVENING...BUT
THEN INCREASE ONCE AGAIN THURSDAY NIGHT INTO FRIDAY MORNING. IN
ADDITION...THE AIRMASS WILL CONTINUE TO DRY WITH LITTLE OR NO
HUMIDITY RECOVERY EXPECTED IN THE HILLS ON THURSDAY NIGHT. THE
STRONGER WINDS WILL GRADUALLY SHIFT SOUTH INTO SANTA
CRUZ...SAN BENITO AND MONTEREY COUNTIES LATER ON THURSDAY. WARMER
AND DRIER WEATHER WILL DEVELOP ON FRIDAY WITH RH VALUES FORECAST
TO DROP INTO THE TEENS AND 20S IN MOST AREAS.

A FIRE WEATHER WATCH REMAINS IN EFFECT FOR ELEVATIONS ABOVE 1000
FEET IN THE NORTH AND EAST BAY HILLS BEGINNING LATE THIS EVENING
AND CONTINUING THROUGH FRIDAY AFTERNOON. A FIRE WEATHER WATCH
REMAINS IN EFFECT FOR ELEVATIONS ABOVE 1000 FEET IN SANTA
CRUZ...MONTEREY AND SAN BENITO COUNTIES FROM THURSDAY AFTERNOON
THROUGH FRIDAY AFTERNOON.

AS A HEADS UP...THE 7-10 DAY FORECAST INDICATES THE POSSIBILITY OF
A STRONGER AND WARMER WIND EVENT THAT WILL MAY IMPACT THE
ENTIRE STATE ON OR ABOUT OCTOBER 3RD.
