Area Forecast Discussion
National Weather Service San Francisco Bay Area
557 PM PDT Fri Nov 4 2016

.SYNOPSIS...Dry and mild into this evening with seasonable
overnight lows. Some increasing clouds Saturday as a weak front
approaches the North Bay with a chance of light rain Saturday
evening for the North Bay. A little cooler Sunday behind the front
but high pressure quickly rebuilds with continued dry and
seasonably mild through the middle of next week.

&&

.DISCUSSION...as of 2:19 PM PDT Friday...Its a mostly sunny and
warm afternoon across the district. Temperatures are currently
running in the 70s with even some lower 80s for some interior warm
spots. With mostly clear skies temperatures will cool into the 40s
and lower 50s for most locations although some of the hills may
remain mild once again overnight. Saturday still looks like a nice
day for outdoor activities with just some increasing clouds and
slightly stronger onshore winds by afternoon allowing for a few
degrees of cooling but still readings hovering around 70.

Front of interest will bring some light rain into the north bay
between 00-06z Saturday evening per the latest 18z nam. Have kept
some likely pops up near the Mendocino border tapering to slight
chance near the Golden Gate. Outside of a stray shower not
expecting much precip to get south of San Francisco. Precip totals
look light with up to 0.15 for the wettest coastal hills of
Sonoma county, otherwise just a few hundredths forecast for most
of the north bay. Meanwhile the greater Bay Area and central coast
will see a dry and mild Saturday evening.

Any showers end by sunrise Sunday (dont forget to turn your clocks
back one hour). High pressure rebuilds Sunday afternoon through
the middle of next week. The synoptic pattern will feature a broad
trough well to our north and west that will keep the bay area in a
mild southwest flow leading to near or slightly above normal
temperatures in the 60s and lower 70s with fairly mild overnight
lows for this time of year as sst are still around 60.

&&

.AVIATION...as of 5:57 PM PDT Friday...An upper level ridge over
California is forecast to shift southward Saturday. VFR area-wide
except patchy valley fog causing LIFR/VLIFR is possible late tonight
and early Saturday under ideal radiational cooling combined with
light and variable drainage winds. 06z Bay Area tafs will indicate
lowering cigs and vsbys Saturday night into Sunday due to light
rain associated with an incoming weakening upper level trough and
surface cold front.

Vicinity of KSFO...VFR. Evening winds westerly 5-10 knots.

SFO Bridge Approach...Similar to KSFO.

Monterey Bay Terminals...VFR. Winds becoming light E-SE this evening.
Onshore winds 5-10 knots return by late Saturday morning or early
afternoon.

&&

effect thru 3 PM This afternoon. Large long period swells will
produce large surf along the coast. Surf along the coast around
15 feet with breaking waves to 20 feet possible through this
afternoon. Seas and surf will subside into the weekend.

&&

.MARINE...as of 01:57 PM PDT Friday...A large and long period nw
swell will continue today then weaken slightly into the weekend.
winds will remain light and then switch to southerly by saturday
ahead of a weak front that will pass north of point reyes saturday
night into sunday. generally light winds later sunday into monday
before another large swell train moves through the waters by
