AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
322 AM PST TUE NOV 26 2013

.DISCUSSION...AS OF 3:22 AM PST TUESDAY...TEMPERATURES ARE RUNNING
SLIGHTLY WARMER THIS MORNING COMPARED TO YESTERDAY...MAINLY DUE TO
INCREASING HIGH CLOUDS COMING IN FROM THE WEST. WEATHER WILL
REMAIN TRANQUIL TODAY WITH FILTERED SUNSHINE UNDER HIGH LEVEL
CIRRUS DECK. NONETHELESS EXPECT COMFORTABLE AFTERNOON READINGS IN
THE 60S ACROSS THE ENTIRE DISTINCT WITH PERHAPS 1-3 DEGREE COOLING TREND.

MODEL CROSS SECTIONS CLEARLY SHOW MID AND HIGH LEVEL CLOUDS
STAYING IN PLACE AGAIN TONIGHT AHEAD OF INCOMING UPPER TROUGH.
THIS WILL PREVENT ANY WIDESPREAD FROST/FREEZE CONCERNS ONCE AGAIN
WITH MOST AREAS COOLING INTO THE 40S EXCEPT SOME 30S ACROSS THE
INLAND WIND PROTECTED VALLEYS. LOOKS LIKE GOOD PRE-THANKSGIVING
TRAVEL WEATHER ACROSS THE BAY AREA AND ENTIRE STATE ON WEDS. THE
INCOMING LOW WILL SLOW DOWN AND TAKE AIM TOWARDS POINT CONCEPTION.
ALSO NOT EXPECTING WIDESPREAD TULE FOG IN THE CENTRAL VALLEY NOR
LOW CIGS AT BAY AREA TERMINALS AT THIS TIME TO IMPACT TRAVEL
LOCALLY.

HAVE NOT MADE MANY CHANGES TO PREVIOUS FORECAST PACKAGE IN TERMS
OF SHOWER CHANCES LATE WEDS NIGHT INTO THANKSGIVING DAY. THE NAM
AND ECMWF MODELS ARE ESSENTIALLY TOTALLY DRY AND WOULD ARGUE FOR A
COMPLETELY DRY FORECAST. HOWEVER FEEL WE NEED TO HONOR THE GEM
MODEL AND LATEST 06Z GFS WHICH STILL GENERATES SOME SHOWERS OVER
THE CENTRAL COAST ON THANKSGIVING DAY AND ROTATES A FEW SHOWERS AS
FAR NORTH AS AROUND SAN JOSE AND THE SANTA CRUZ MOUNTAINS.
FORECAST WILL MAINTAIN CHANCE AND SLIGHT CHANCE SHOWERS ON
THANKSGIVING DAY WITH BEST CHANCES SOUTH OF MONTEREY INCLUDING THE
BIG SUR COAST AND POINTS SOUTHWARD. ANY SHOWERS THAT DEVELOP LOOK
TO BE LIGHT AND SCATTERED WITH QPF NUMBERS ON THE ORDER OF A FEW
HUNDREDTHS TO PERHAPS A TENTH IN THE SANTA LUCIAS.

THE NORTH BAY MAY BENEFIT FROM FAVORABLE EASTERLY FLOW AROUND THE
CIRCULATION LEADING TO PARTLY CLOUDY AND MILD WEATHER FOR
THANKSGIVING WITH LITTLE OR NO THREAT OF PRECIP NORTH OF THE
GOLDEN GATE.

WILL HANG ON TO SOME SLIGHT SHOWER CHANCES THROUGH EARLY FRIDAY
OVER MONTEREY AND SAN BENITO COUNTY BUT BY FRIDAY AFTERNOON THE
LOW SHOULD PUSH EASTWARD TO END ANY SHOWER THREAT.

HIGH PRESSURE WILL BUILD FRIDAY AFTERNOON AND THROUGH THE WEEKEND
WITH MOSTLY CLEAR SKIES AND SEASONABLY MILD TEMPERATURES.

LONG RANGE FORECAST IS LOOKING MORE AND MORE INTERESTING WITH
FAIRLY GOOD MODEL AGREEMENT FOR A COLD FRONTAL PASSAGE BY NEXT
MONDAY OR TUESDAY WITH SUBSEQUENT WEATHER SYSTEMS. INCREASING
CONFIDENCE THAT BAY AREA AND NORTHERN CALIFORNIA WILL AT LEAST
TEMPORARILY BE POSITIONED IN MORE FAVORABLE LOCATION OF LONGWAVE
TROUGH TO POTENTIALLY BRING SOME MUCH NEED EARLY WINTER RAINFALL
AS THE CALENDER TURNS TO DECEMBER.

&&

.AVIATION...AS OF 10:00 PM PST MONDAY...DRY AIR COMBINED WITH
LIGHT OFFSHORE WINDS TO KEEP VFR CONDITIONS GOING THROUGH THE
PERIOD. ONLY POTENTIAL PROBLEM AREA WOULD BE KSTS DUR TO FOG AND
LOW CIGS TONIGHT.

VICINITY OF KSFO...LIGHT WINDS WITH VFR CONDITIONS THROUGH THE
PERIOD. HIGH CONFIDENCE.

KSFO BRIDGE APPROACH...SIMILAR SFO.

MONTEREY BAY AREA TERMINALS...VFR THROUGH THE PERIOD WITH LIGHT WINDS.
HIGH CONFIDENCE.

.MTR WATCHES/WARNINGS/ADVISORIES...
     .TDAY...NONE.
