AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
1054 PM PDT MON JUN 18 2012

.DISCUSSION...AS OF 8:55 PM PDT MONDAY...THE MARINE PUSH WHICH
BEGAN YESTERDAY CONTINUED THROUGH TODAY. THE INLAND INFLUX OF COOL
MARINE AIR BECAME SOMEWHAT MORE EFFICIENT LAST NIGHT AND TODAY AS
THE MARINE LAYER DEEPENED PAST 1500 FEET. THE MAGNITUDE OF TODAY'S
COOLING WAS GREATEST IN IN THE HILLS AND IN SOME OF THE INLAND
VALLEYS WHERE TEMPERATURES WERE AS MUCH AS 20 DEGREES COOLER
COMPARED TO YESTERDAY.

WATER VAPOR SATELLITE IMAGERY THIS EVENING SHOWS AN UPPER TROUGH
CARVING OUT ACROSS THE PAC NW AND NORTHERN ROCKIES. SURFACE HIGH
PRESSURE IS RAPIDLY BUILDING TO THE WEST OF THE TROUGH AXIS ALONG
THE OREGON COAST AND NW CA. THE ACV-SFO GRADIENT HAS ALREADY
INCREASED TO 7.4 MB AND MOST LOW CLOUDS HAVE BEEN SWEPT FROM
COASTAL AREAS NORTH OF MONTEREY BAY AS A RESULT. WOULD EXPECT SOME
REDEVELOPMENT OF COASTAL LOW CLOUDS FROM THE GOLDEN GATE SOUTHWARD
OVERNIGHT AS NEAR SHORE WINDS EASE...BUT DEVELOPMENT OF LOW CLOUDS
IN SF BAY MIGHT BE SOMEWHAT MORE LIMITED THAN PREVIOUSLY THOUGHT
DUE TO THE QUICK INCREASE IN NORTHERLY GRADIENTS. A FORECAST
UPDATE WAS RECENTLY COMPLETED TO SCALE BACK SOMEWHAT ON LOW CLOUDS
AND FOG IN THE SF BAY AREA TONIGHT AND TUESDAY MORNING.

FROM PREVIOUS DISCUSSION... THE DEVELOPING THERMAL TROUGH ALONG
THE COAST WILL INDUCE SOME LIGHT TO MODERATE NORTHEAST WINDS IN
THE HILLS TONIGHT...MAINLY FOCUSED OVER THE NORTH BAY HILLS.
LATEST OBSERVATIONS AND MODEL DATA SHOW THE NORTHEAST WIND EVENT
TO BE FAIRLY LIGHT...SHORT IN DURATION AND NOT COVERING MUCH
GEOGRAPHY. THUS FIRE WEATHER CONCERNS WILL BE MINIMIZED WITH
PRETTY GOOD RH RECOVERY MOST LOCATIONS AS WELL WITH THE ONSHORE
TRENDS.

HOWEVER THE NORTHERLY GRADIENT WILL CONTINUE INTO TUESDAY MORNING
AND ALLOW FOR A RAPID REBOUND IN TEMPERATURES...ESPECIALLY FOR THE
NORTH BAY VALLEYS WITH KSTS WARMING AT LEAST INTO THE MID AND UPPER
80S WITH NEAR 90 FOR THE EAST BAY VALLEYS. NOT TOO MUCH CHANGE
EXPECTED ON WEDS WITH WARM INLAND TEMPERATURES AGAIN...HOWEVER A
STRONGER SEA-BREEZE IS LIKELY BY WEDS AFTERNOON AND EVENING AS A
TROUGH OFF THE COAST APPROACHES.

GOOD MODEL CONSENSUS FOR A NOTED COOLING TREND STARTING ON
THURSDAY AS A LARGE SCALE TROUGH BEGINS TO IMPACT THE WEST COAST.
RAIN WILL APPROACH AREAS NORTH OF CAPE MENDOCINO BY FRIDAY NIGHT
OR SATURDAY WITH PERHAPS SOME DRIZZLE ALONG OUR COAST BUT AS WOULD
BE EXPECTED NOT EXPECTING ANY RAINFALL FOR OUR DISTRICT. MAIN
WEATHER STORY THROUGH THE WEEKEND WILL BE THE BELOW NORMAL
TEMPERATURES...ESPECIALLY FOR INLAND LOCATIONS. FOR EXAMPLE
LIVERMORE NOW AVERAGES A DAYTIME HIGH IN THE MID 80S AND AFTERNOON
READINGS THIS WEEKEND WILL STRUGGLE TO REACH THE MID 70S.

&&

.AVIATION...AS OF 10:50 PM PDT MONDAY...THE STRONG 7 MB NORTHERLY
GRADIENT CONTINUES FROM ARCATA TO SAN FRANCISCO LEAVING LITTLE IN
THE WAY OF STRATUS ALONG THE NORTHERN AND CENTRAL CALIFORNIA
COAST. HAVE UPDATED THE TERMINAL FORECAST TAKING ALL CIGS OUT OF
BAY AREA TERMINALS. CONFIDENCE IS MODERATE. KMRY AND KSNS WILL SEE
STRATUS RETURN TONIGHT.

VICINITY OF KSFO...VFR CONDITIONS WILL CONTINUE THROUGH TONIGHT.
WINDS WILL REMAIN PREDOMINATELY WEST BUT LIKELY TO BACK TO THE
SOUTHWEST OR BECOME SOMEWHAT VARIABLE OVERNIGHT AND INTO THE EARLY
MORNING HOURS.

KSFO BRIDGE APPROACH...SIMILAR TO SFO.

MONTEREY BAY AREA TERMINALS...IFR CIGS ANTICIPATED TO RETURN TONIGHT.
WINDS WILL BECOME LIGHT AND VARIABLE OVERNIGHT. CLEARING ANTICIPATED
AROUND 18Z TUESDAY MORNING.

&&

.CLIMATE...SUMMER SOLSTICE OCCURS AT 4:09 PM PDT...WEDNESDAY JUNE 20.

.MTR WATCHES/WARNINGS/ADVISORIES...
