AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
657 PM PST TUE FEB 2 2016

.SYNOPSIS...AFTER A BRIEF BREAK IN PRECIPITATION THIS EVENING AND
OVERNIGHT, LIGHT RAINFALL WILL RETURN TO THE NORTH BAY WEDNESDAY
MORNING AND SPREAD INTO THE SAN FRANCISCO BAY AREA BY WEDNESDAY
AFTERNOON. OVERALL, RAINFALL AMOUNTS WILL REMAIN LIGHT WITH NO
MEASURABLE PRECIPITATION EXPECTED SOUTH OF THE SAN JOSE REGION.
HIGH PRESSURE WILL THEN BUILD ALONG THE WEST COAST FOR LATE WEEK
AND INTO THE WEEKEND. THIS WILL RESULT IN DRY WEATHER CONDITIONS
AND WARMING TEMPERATURES INTO EARLY NEXT WEEK.

&&

.DISCUSSION...AS OF 02:00 PM PST TUESDAY...PRECIPITATION
CONTINUES TO DIMINISH IN COVERAGE THIS AFTERNOON IN WAKE OF
TODAY'S WEATHER SYSTEM. ONSHORE FLOW AND LINGERING MOISTURE HAS
ALLOWED FOR GOOD CU DEVELOPMENT OVER THE COASTAL RANGES WITH
TEMPERATURES GENERALLY IN THE LOW TO MID 50S. MEANWHILE, HIGHER
ELEVATIONS ARE SEEING TEMPERATURES IN THE 40S. QUIET WEATHER
CONDITIONS WILL PERSIST DURING THE OVERNIGHT HOURS WITH
TEMPERATURES FALLING INTO THE MID/UPPER 30S INLAND TO LOWER 40S
NEAR THE COAST/BAYS ALONG WITH WEAK SURFACE WINDS.

OUR NEXT, WEAK WEATHER SYSTEM WILL APPROACH THE NORTH BAY
WEDNESDAY MORNING AND SPREAD DOWN INTO THE SAN FRANCISCO BAY AREA
BY LATE MORNING OR EARLY AFTERNOON. OVERALL, RAINFALL FROM THIS
SYSTEM WILL BE LIGHT WITH MOST URBAN AREAS FROM SAN JOSE NORTHWARD
LIKELY PICKING UP A FEW HUNDREDTHS OF AN INCH OR SO. THE NORTH BAY
REGION WILL RECEIVE THE MOST RAINFALL FROM THIS SYSTEM, GENERALLY
1/10" TO 1/4" IN THE VALLEYS AND UP TO 1/2" IN THE COASTAL RANGES.
LOCATIONS FROM THE SANTA CRUZ MOUNTAINS SOUTHWARD THROUGH THE
MONTEREY BAY REGION WILL LIKELY REMAIN DRY AS THE SYSTEM SHIFTS
INLAND. PRECIPITATION OVER THE NORTH BAY MAY LINGER INTO WEDNESDAY
EVENING/NIGHT, BUT DIMINISH IN COVERAGE WITH DRY CONDITIONS
DEVELOPING REGION-WIDE LATE IN THE NIGHT.

A RIDGE OF HIGH PRESSURE WILL CONTINUE TO BUILD OVER THE REGION
BEGINNING ON THURSDAY AND PERSISTING INTO EARLY NEXT WEEK. THIS
WILL RESULT IN MOSTLY DRY CONDITIONS REGION-WIDE LATE WEEK AND
INTO THE WEEKEND AS THE MAIN STORM TRACK STAYS WELL NORTH OF THE
REGION. CONFIDENCE CONTINUES TO INCREASE IN THE RIDGE BUILDING
ALOFT AND WARMING TEMPERATURES THROUGH THE WEEKEND. BY THIS
WEEKEND, AFTERNOON TEMPERATURES WILL WARM INTO THE MID/UPPER 60S
IN COASTAL AREAS AND INTO THE LOW TO MID 70S OVER THE SOUTHERN
INLAND VALLEYS (A GOOD 10 DEGREES ABOVE SEASONAL AVERAGES).

GIVEN THE RECENT RAINFALL AND INCREASED SOIL MOISTURE, WE WILL
NEED TO WATCH FOR THE DEVELOPMENT OF TULE FOG LATE IN THE WEEK AND
INTO THE WEEKEND. ESPECIALLY WITH WEAK OFFSHORE FLOW POTENTIALLY
DEVELOPING OVER THE REGION AS A RESULT OF THE RIDGE ALOFT.
HOWEVER, CONFIDENCE IN THIS DEVELOPING AND ACTUALLY IMPACTING THE
SAN FRANCISCO BAY AREA REMAINS LOW AT THIS TIME AND THERE IS NO
MENTION OF FOG IN THE OFFICIAL FORECAST. WILL CONTINUE TO WATCH
FOR THIS POTENTIAL AS WE MOVE TOWARD LATE WEEK.

&&

.AVIATION...AS OF 6:45 PM PST TUESDAY...A WARM FRONT APPROX 250
MILES WEST OF NORCAL WILL ADVANCE TOWARD THE AREA TONIGHT AND
WEDNESDAY. SURFACE WINDS 5-10 KNOT RANGE SHOULD BE ENOUGH TO
PRECLUDE FOG DEVELOPMENT THIS EVENING. LESS CONFIDENT ABOUT EARLY
WEDNESDAY MORNING TIMEFRAME REGARDING FOG COVERAGE HOWEVER GIVEN
RECENT WET WEATHER AND IF WINDS HAPPEN TO DECREASE TO 3-5 KNOT
RANGE FOG COVERAGE COULD BE A BIT MORE WIDESPREAD EARLY WEDNESDAY
MORNING. IFR DUE TO FOG FORECAST KSTS 11Z-18Z WED.

AN EASTERN PACIFIC COLD FRONT RAPIDLY CATCHES UP TO THE WARM
FRONT OVER THE BAY AREA LATE WEDNESDAY PM WITH POSSIBLE BRIEFLY
FOCUSED ATMOSHPERIC FORCING NEAR COLD FRONTAL PASSAGE WEDNESDAY
EVENING SUPPORTING SHOWERS FORECAST...MOSTLY CONFINED TO THE BAY
AREA PER NAM MODEL FORECASTS. THE SURFACE TROUGH WILL BE IN
WEAKENING STAGES BUT THE COLD FRONT LOOKS MODERATELY INTACT WHEN
IT ARRIVES. MID LEVEL INSTABILITY MAY BRIEFLY RAMP UP LATE WED
AFTERNOON OR EARLY EVENING OVER THE NORTH BAY.

VICINITY OF KSFO...RECENTLY AMENDED TAF FOR PERSISTENT NE WIND
WITH 1 MIN OBS RECENTLY SUSTAINING NEAR 14 KNOTS. WINDS SHOULD
GRADUALLY SUBSIDE OVERNIGHT WITH A SHIFT TO SE LATE AT NIGHT. VFR
TONIGHT. MVFR CIGS WEDNESDAY. SHOWERS POSSIBLE BY LATE IN THE DAY.

SFO BRIDGE APPROACH...SIMILAR TO KSFO.

MONTEREY BAY AREA TERMINALS...ONSHORE WINDS LESS THAN 10 KNOTS
BECOMING LIGHT SE TONIGHT. VFR/MVFR CIGS.

&&

.MARINE...AS OF 02:00 PM PST TUESDAY...LIGHT NORTHERLY WINDS WILL
PERSIST THROUGH THIS EVENING THEN INCREASE AND SHIFT TO THE SOUTH
TO SOUTHEAST OVERNIGHT ACROSS THE NORTHERN OUTER WATERS AS A
SYSTEM APPROACHES FROM THE WEST. A LONG PERIOD WESTERLY SWELL WILL
ARRIVE WEDNESDAY NIGHT INTO THURSDAY.

&&

.MTR WATCHES/WARNINGS/ADVISORIES...
     .TNGT...NONE.
