AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
959 AM PST TUE JAN 21 2014

.DISCUSSION...AS OF 09:42 AM PST TUESDAY...AN INCREASE IN HIGH
LEVEL CLOUDS ACROSS THE REGION CAN BE SEEN THIS MORNING ON VIS
SATELLITE IMAGERY. THICKER...MID-LEVEL CLOUDS ASSOCIATED WITH A
WEAK MID/UPPER LEVEL LOW REMAIN TO OUR SOUTH AND CONTINUE TO PUSH
NORTHWARD. IF THE THICKER CLOUD COVER WORKS INTO THE CENTRAL COAST
EARLY ENOUGH...AFTERNOON TEMPERATURES MAY BE COOLER THAN CURRENTLY
FORECAST. HOWEVER...DO EXPECT ANOTHER ROUND AFTERNOON TEMPERATURES
WELL ABOVE AVERAGE AGAIN TODAY FOR ALL OF THE REGION. COOLER
CONDITIONS AT THE COAST WITH THE POSSIBILITY OF A WEAK SEA-BREEZE
DEVELOPING. OTHERWISE...THE FORECAST FOR TODAY REMAINS ON TRACK
AND NO MAJOR CHANGES ARE NEEDED AT THIS TIME.

&&

.PREV DISCUSSION...AS OF 2:59 AM PST TUESDAY...A SHALLOW MARINE LAYER
CONTINUES OVER THE OCEAN WITH DENSE FOG REPORTED OVERNIGHT AT HALF
MOON BAY AND MONTEREY. GOES-W DATA SHOWS CLOUDS HEIGHTS UNDER 1000
FEET SO DON'T EXPECT IT TO SURGE INLAND BEYOND A MILE OR TWO THIS
MORNING ALONG THE COAST. ANOTHER DAY OF SUNNY AND UNSEASONABLY
WARM TEMPERATURES IN STORE FOR THE ENTIRE DISTRICT WITH WIDESPREAD
READINGS WELL INTO THE 60S AND LOWERS 70S WITH UPPER 70S OVER
INTERIOR MONTEREY AND SAN BENITO COUNTIES AGAIN. THE FOG LAYER
NEAR THE COAST WILL KEEP THE BEACHES SLIGHTLY COOLER.

IF ANYTHING EXPECT TEMPERATURES TO SPIKE HIGHER AGAIN ON WEDS AS
HIGH PRESSURE REBUILDS...850 MB TEMPS APPROACH 15 CELSIUS AND A
MORE FAVORABLE NORTH/NORTHEAST OFFSHORE FLOW SETS UP ACROSS THE
REGION BY WEDS AFTERNOON. BOTTOM LINE IS MORE SUNSHINE AND WARM TEMPS.

WE'VE BEEN WATCHING A SHORTWAVE OF INTEREST THAT WILL RIDE UP AND
OVER THE RIDGE AND THEN...LIKE A BREAKING WAVE DROP STRAIGHT
SOUTHWARD INTO NEVADA. AS THIS HAPPENS A STRONG OFFSHORE SURFACE
PRESSURE GRADIENT WILL SET-UP OVER THE SIERRA AND TOWARDS THE
COAST. IN GENERAL AS THE EVENT NEARS MODELS ARE BACKING OFF ON THE
STRENGTH OF WINDS AND PUBLIC WIND ADVISORIES LOOK UNLIKELY AT THIS
TIME. FIRE WEATHER CONCERNS WILL STILL BECOME ELEVATED AS ANOTHER
FALL LIKE OFFSHORE WIND EVENT APPEARS LIKELY BUT WIND SPEEDS
APPEAR MARGINAL. HOWEVER HUMIDITY VALUES WILL BE VERY DRY AND
FUELS REMAIN AT RECORD DRY MID-WINTER LEVELS.

WE'D EXPECT THE GREAT BASIN SHORTWAVE TO EJECT EASTWARD BUT THE
FLOW BECOMES BLOCKED AS ARCTIC AIR AND A 1050 MB SFC HIGH DROPS OVER
THE GREAT PLAINS AND EASTERN US. THEREFORE THE SHORTWAVE IS
PROGGED TO RETROGRADE WESTWARD OVER NORTHERN CALIFORNIA BEFORE
BEING INJECTED BACK INTO THE MAIN WESTERLIES. EARLIER THIS WEEK
THE MODELS WEREN'T SHOWING THIS WHICH PORTENDED THE POTENTIAL FOR
STRONGER WINDS...THAT NOW APPEAR UNLIKELY...LETS CALL IT BREEZY IN
THE HILLS AT TIMES THURSDAY AND FRIDAY.

AS THE 500 MB UPPER LOW RETROGRADES ACROSS NORTHERN CALIFORNIA ON
FRIDAY A SOUTHERLY WIND REVERSAL WILL DEVELOP OVER THE OCEAN AND
CENTRAL CALIFORNIA. THIS MAY PRODUCE A BIZARRE TEMPERATURE PATTERN
WHERE THE NORTH BAY BENEFITS FROM NORTHEASTERLY DOWN-SLOPE WINDS
WHILE PLACES LIKE SANTA CRUZ RECEIVE A COLD SOUTH WIND OFF THE
OCEAN. STILL A LITTLE TOO FAR OUT TO GET CUTE WITH THE
TEMPERATURE DETAILS. THE UPPER LOW WILL LIFT NORTHWARD AND ANOTHER
WEEKEND OF SUNNY...WARM AND DRY LOOKS TO BE IN THE CARDS.

THE ECMWF HAD BEEN CONSISTENT FOUR STRAIGHT RUNS IN BRINGING A
SYSTEM TO NORTHERN CALIFORNIA BY JAN 27/28. THE 00Z RUNS BACKED
OFF AND WERE NOW LOOKING AT THE VERY REAL POSSIBILITY OF NO MORE
RAIN CHANCES THIS MONTH IF THE MODEL ENSEMBLES ARE CORRECT. SIGH.

&&

.AVIATION...AS OF 9:25 AM PST TUESDAY...VFR CONDITIONS WILL
PREVAIL THROUGH THE FORECAST. ALL OF THE SHORT TERM MODELS
INDICATE THAT LIGHT OFFSHORE FLOW WILL BECOME ONSHORE BY 00Z
WEDNESDAY...RESULTING IN A BIT STRONGER ONSHORE WINDS COMPARED TO
YESTERDAY...BUT GENERALLY BELOW 10 KT. HIGH CONFIDENCE.

VICINITY OF KSFO...VFR.

KSFO BRIDGE APPROACH...VFR.

MONTEREY BAY AREA TERMINALS...VFR.

&&

.FIRE WEATHER...AS OF 2:59 AM TUESDAY...LIGHT TO MODERATE
NORTHEAST WINDS FROM LATE WEDS THROUGH FRIDAY WILL CREATE ELEVATED
FIRE WEATHER CONCERNS. HOWEVER CONDITIONS DON'T LOOK AS BAD AS
EARLIER THOUGHT AS WINDS SPEEDS HAVE BACKED OFF CONSIDERABLY.
HOWEVER RH VALUES LOOK TO REMAIN VERY DRY WITH PROLONGED PERIOD OF
OFFSHORE WINDS AND OF COURSE CONTINUED DRY FUEL BED. WINDS MAY
EASE BY FRIDAY BUT THEN CONTINUED WARM AND DRY THROUGH THE WEEKEND
WITH NO RAIN IN SIGHT.

&&

.CLIMATE...

RECORD HIGH TEMPERATURES FOR TUESDAY AND WEDS FOR REFERENCE.
