AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
830 PM PDT FRI JUN 15 2012

.DISCUSSION...AS OF 8:30 PM PDT FRIDAY...UNDER SUNNY SKIES
TODAY...AFTERNOON TEMPERATURES WERE ALMOST UNANIMOUSLY WARMER THAN
YESTERDAY'S HIGHS WITH READINGS RANGING FROM THE MID 50S TO LOWER
60S AT THE COAST TO THE UPPER 90S INLAND. MOST PLACES WERE SEVERAL
DEGREES WARMER THAN THURSDAY...BUT SOME WERE AS MANY AS 10-15
DEGREES WARMER. THE ONE EXCEPTION I COULD FIND WAS BUG SUR
STATION...WHOSE 64 DEGREE HIGH TODAY WAS 14 DEGREES COOLER THAN
WHAT WAS RECORDED YESTERDAY. CURRENT SATELLITE IMAGERY SHOWS
MOSTLY CLEAR SKIES OVER THE REGION...WITH JUST SOME HIGH CLOUDS
MOVING ACROSS THE BAY AREA. TEMPERATURES ARE STILL MILD...AND
EXPECT A MUCH WARMER NIGHT MOST SPOTS ALONG WITH MAINLY CLEAR
SKIES. THE ONLY EXCEPTION MIGHT BE SOME PATCHY FOG FORMING IN THE
MONTEREY BAY TOWARDS SUNRISE.

SURFACE PRESSURE GRADIENTS CONTINUE TO BE QUITE STRONG FROM NORTH
TO SOUTH WITH 9.1 MB BETWEEN ARCATA AND SFO. THE SFO TO SAC GRADIENT
IS MODERATE ONSHORE WITH 2.9 MB...BUT THE WMC-SFO GRADIENT IS
STARTING TO TIGHTEN AND IS CURRENTLY AT 3.9 MB. BY 12Z THE 00Z NAM
PREDICTS THIS GRADIENT WILL TIGHTEN TO 9.8 MB. AS THIS HAPPENS...THE
OFFSHORE WINDS WILL CONTINUE TO RAMP UP ESPECIALLY IN THE NORTH
BAY MOUNTAINS. LOWERING RH VALUES IN ADDITION TO THESE WINDS VALIDATE
THE RED FLAG WARNING IN EFFECT FOR THE NORTH BAY MOUNTAINS TONIGHT.

FROM PREVIOUS DISCUSSION...THE MOSTLY CLEAR REGIME IS EXPECTED TO
CONTINUE THROUGH SATURDAY. THE EXCEPTION WILL BE ALONG THE COAST
SOUTH OF BIG SUR AS SOUTHERLY SURGE OF MARINE STRATUS IS LIKELY TO
DEVELOP SATURDAY AFTERNOON. TEMPERATURES WILL BE CONSIDERABLY
WARMER SATURDAY WITH SOME 100 DEGREE READINGS EXPECTED IN THE
INTERIOR VALLEYS.

NAM USUALLY DOES A PRETTY GOOD JOB OF PICKING UP SOUTHERLY
SURGE...BUT CAN OFTEN BE A LITTLE SLOW AT EXPANDING IT NORTHWARD
ALONG COAST. CURRENT INDICATIONS ARE THE STRATUS WILL SPREAD NORTH
ALONG COAST INTO MONTEREY BAY BY SATURDAY EVENING AND MOVE UP THE
ENTIRE CWA COASTLINE BY 15Z SUNDAY. WITH STRONG RIDGE
OVERHEAD...WOULD EXPECT MARINE LAYER TO REMAIN SHALLOW UNDER 1000
FEET INTO SUNDAY. ONSHORE PRESSURE GRADIENT INCREASES WITH SFO-
WMC GRADIENT APPROACHING 10 MB ONSHORE BY SUNDAY NIGHT. COOLER
CONDITIONS ANTICIPATED SUNDAY ESPECIALLY NEAR THE COAST AND INTO
COASTAL VALLEYS. MARINE LAYER WILL DEEPEN SUNDAY NIGHT WITH COOLER
CONDITIONS EXTENDING THROUGHOUT THE INTERIOR MONDAY.

MEDIUM RANGE MODELS IN REASONABLE AGREEMENT EARLY IN THE
PERIOD...THEN DIVERGE SOMEWHAT TOWARD MIDWEEK. CURRENTLY LEANING
TOWARD ECMWF WITH LESS AMPLIFIED TROF OVER GREAT BASIN
WEDNESDAY...IMPLYING LESS CHANCE OF ANOTHER SIGNIFICANT OFFSHORE
WIND EVENT. NOT TOTALLY CONVINCED ECMWF WILL VERIFY PERFECTLY AS
GFS ENSEMBLE MEMBERS SUPPORT OPERATIONAL GFS RUN PRETTY WELL.
LEANED TOWARD PREVIOUS OFFICIAL FORECAST WITH TEMPERATURES TOWARD
MIDWEEK BEING SOMEWHAT WARMER WITH THE POTENTIAL FOR WEAK OFFSHORE
FLOW MAINLY NORTH BAY. AFTER SIGNIFICANT MARINE PUSH MONDAY...WOULD
EXPECT SOME TEMPERATURE RECOVERY OVER THE INTERIOR BY MIDWEEK ANYWAY.

CLIMATOLOGICALLY FAVORED SUMMERTIME RIDGE BUILDS OVER GREAT BASIN
LATE IN THE WEEK BRINGING SOUTHWEST FLOW ALOFT TO CENTRAL
CALIFORNIA COAST. SHOULD SEE ANOTHER INLAND SURGE OF MARINE AIR BY
THAT TIME.

&&

.AVIATION...AS OF 4:40 PM PDT FRIDAY...DEVELOPING OFFSHORE FLOW IS
EXPECTED TO MAINTAIN VFR CONDITIONS ACROSS THE SF BAY AREA THROUGH
SATURDAY...AND PROBABLY AROUND MONTEREY BAY AS WELL. THERE IS A SLIGHT
CHANCE OF LOW CIGS AT KMRY OVERNIGHT...BUT DOES NOT APPEAR LIKELY.
CONFIDENCE MEDIUM-HIGH.

VICINITY OF KSFO...VFR THROUGH THE FORECAST PERIOD. MODERATE
ONSHORE FLOW THIS EVENING WILL DECREASE OVERNIGHT AND TURN
OFFSHORE LATE TONIGHT AND SATURDAY MORNING. LOW LEVEL WIND SHEAR
POSSIBLE VCNTY KOAK LATE TONIGHT INTO SATURDAY MORNING.

KSFO BRIDGE APPROACH...SIMILAR AS KSFO.

MONTEREY BAY AREA TERMINALS...VFR LIKELY THROUGH SATURDAY ALTHOUGH
THERE IS A SLIGHT CHANCE THAT IFR/MVFR CIGS COULD DEVELOP AT KMRY
OVERNIGHT.

&&

.FIRE WEATHER...AS OF 2:30 PM PDT FRIDAY...A RED FLAG WARNING FOR
THE NORTH BAY MOUNTAINS IS VALID FOR TONIGHT AND EARLY SATURDAY.
OFFSHORE FLOW WILL DEVELOP ESPECIALLY IN THE NORTH BAY BY THIS
EVENING WITH WINDS INCREASING OVER THE MOUNTAINS AND GUSTING TO 40
MPH OVERNIGHT. WIND COMBINED WITH LOWER HUMIDITY AND MINIMAL
RECOVERY TO 30% OR LOWER IN THE MOUNTAINS PROMPTED THE RED FLAG
ISSUANCE. WINDS SHOULD GRADUALLY DECREASE SATURDAY WITH A RETURN
TO ONSHORE FLOW NEAR THE COAST SATURDAY NIGHT. POOR HUMIDITY
RECOVERY IS EXPECTED IN THE MOUNTAINS TONIGHT WITH ONLY SLIGHTLY
HIGHER RH SATURDAY NIGHT. STRONGER ONSHORE FLOW SUNDAY AND
DEEPENING MARINE LAYER SUNDAY NIGHT SHOULD BRING HIGHER RH
RECOVERY TO ALL ZONES.
