AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
425 AM PDT TUE OCT 1 2013

.DISCUSSION...AS OF 3:52 AM PDT TUESDAY...SKIES ARE MOSTLY CLEAR
THIS MORNING ACROSS THE DISTRICT EXCEPT FOR SOME PATCHY CLOUDS
AROUND MONTEREY BAY. KWVI AND KSNS ARE REPORTING SOME DENSE FOG AS
WELL BUT THE GREATER BAY AREA SHOULD START THE MORNING OUT MOSTLY CLEAR.

SYNOPTIC PATTERN WILL FEATURE ONSHORE PRESSURE GRADIENTS WITH A
ZONAL FLOW ALOFT. THIS WILL BRING QUIET WEATHER UNDER MOSTLY CLEAR
SKIES WITH SEASONABLE TEMPERATURES FROM THE UPPER 60S COAST WITH
MOST AREAS 70S TO LOWER 80S TODAY INTO WEDNESDAY.

MAIN WEATHER FEATURE WE'LL BE WATCHING THE NEXT SEVERAL DAYS WILL
BE AN OFFSHORE WIND EVENT AND ASSOCIATED FIRE WEATHER CONCERNS
ACROSS THE BAY AREA AS WELL AS SOUTHERN CALIFORNIA THURSDAY AND
INTO THE WEEKEND.

AN INSIDE SLIDER WILL DROP INTO NEVADA LATE WEDS NIGHT INTO
THURSDAY. THIS PATTERN IS ACTUALLY FAIRLY SIMILAR TO WHAT WAS
OBSERVED LAST WEEK AROUND THE SAME TIME. WERE EXPECTING WINDS TO
TO TURN NORTH/NORTHEAST AS EARLY AS THURSDAY MORNING IN THE HILLS
WHICH WILL ALLOW TEMPERATURES TO WARM-UP A FEW DEGREES BY THURSDAY
AFTERNOON.

SURFACE AND UPPER AIR PATTERN SUPPORT INCREASING OFFSHORE WINDS
LATE THURSDAY INTO FRIDAY WHEN 925 MB WINDS ARE FORECAST TO BE
SUSTAINED FROM 25-35 KT ACROSS THE GREATER BAY AREA WITH RAPID
DRYING OF HUMIDITY VALUES. MOST OBVIOUS CONCERN WILL BE POTENTIAL
FOR ANOTHER ROUND OF RED FLAG WARNINGS...MOST FOCUSED OVER THE
NAPA AND EAST BAY HILLS. WILL HOLD OFF ON ANY FIRE WEATHER WATCHES
FOR NOW AND LET DAY SHIFT COORDINATE WITH CUSTOMERS AND
SURROUNDING WFOS. AT THIS TIME THE WINDS ON THURSDAY NIGHT INTO
FRIDAY LOOK STRONGER THAN WHAT WAS OBSERVED LAST WEEK AND MORE
WIDESPREAD AS WELL. RAIN TOTALS YESTERDAY WERE GENERALLY UNDER A
TENTH FOR MOST OF THE AREA EXCEPT 0.25 FAR NORTHERN NAPA AND
SONOMA...BUT GENERAL IDEA IS THAT WE HAVE ONLY HAD SEASON SLOWING
AND NOT SEASON ENDING RAINS SO FAR. WILL EVEN HAVE TO CONSIDER
WIND ADVISORIES FOR THE PUBLIC FORECASTS.

NO MATTER WHATS ISSUED IN TERMS OF WARNINGS AND ADVISORIES LATER
IN THE WEEK...TEMPERATURES WILL WARM TO ABOVE NORMAL WITH WARM TO
HOT READINGS ACROSS THE AREA FRIDAY AND SATURDAY AS CLASSIC EARLY
OCTOBER OFFSHORE WIND EVENT SETS-UP OVER NORTHERN CALIFORNIA.

PERHAPS SOME MINOR COOLING BY SUNDAY AS ANOTHER SYSTEM MOVES INTO
THE PACIFIC NORTHWEST BUT THEN THE GFS AND ECMWF HINT AT ANOTHER
OFFSHORE WIND EVENT BY EARLY NEXT WEEK...SO A PROLONGED PERIOD OF
SUNNY AND WARM WEATHER WITH FIRE WEATHER CONCERNS REMAINING
ELEVATED ACROSS MUCH OF THE STATE FROM THE BAY AREA SOUTHWARD.

.AVIATION...AS OF 4:30 AM PDT TUESDAY...MARINE LAYER REMAINS MIXED
OUT KEEPING EXTENSIVE STRATUS FROM FORMING IN THE SFO BAY AREA.

VICINITY OF KSFO...VFR.
