What forecasters said that day

The local office's own words before this small craft advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS San Francisco Bay Area, CA wrote its last area forecast discussion before this small craft advisory went out at Mar 8, 1:39 PM PST, 42 minutes earlier.

Area forecast discussion, Mar 8, 1:39 PM PST, 42 minutes before
Area Forecast Discussion
National Weather Service San Francisco Bay Area
139 PM PST Fri Mar 8 2019

.SYNOPSIS...Light shower activity across the Monterey Bay will
taper off through the afternoon and evening. A different storm
system will bring another shot of beneficial rain tomorrow with
lingering showers into tomorrow night. Dry high pressure returns
Monday with another chance of light rain by Tuesday as another
fast moving system passes through.

&&

.DISCUSSION...as of 01:45 PM PST Friday...A weak disturbance
passing through California has helped to excite a broad unstable
airmass in place across the state and the nearby coastal waters.
Visible satellite imagery depicts scattered cumulus clouds
developing in this unstable air mass while KMUX radar shows light
to moderate returns under the deeper convective cells. Radar
returns have generally been below the threshold that would signify
hail while convective cloudtops are at a relatively shallow
5000-10000 feet. That said, convective shower activity has been
slightly more robust and widespread than models suggested, with
isolated showers as far north as the Golden Gate into the early
afternoon. The bulk of the shower activity has been focused across
the Monterey Bay and Big Sur regions, where generally 0.05-0.20"
of rain has fallen since midnight. Showers will likely continue
across the Monterey Bay region through the afternoon before
finally tapering off later this evening.

Temperatures began the day 3 to 10 degrees cooler than the
previous morning given the cooler air mass and pockets of mostly
clear skies, but are now running in line with yesterdays mid 50s
readings. These temperatures are roughly 8 to 12 degrees below
normal readings for early March. Temperatures tonight are expected
to be slightly cooler than last night, particularly for the inland
portions of the region though overnight lows may be limited by
increased cloud covering from an approaching storm system set to
arrive Saturday morning.

Short term forecast models generally agree that a storm system
currently 600 miles west of Point Mendocino will begin to spread
another round of precipitation across the region prior to sunrise
Saturday morning. Lighter warm sector precipitation should give
way to occasionally moderate frontal precipitation shortly after
sunrise for the North Bay before shifting southward and inland
through the day. The local WRF and HRRR suggest that the frontal
precipitation will shift south of the Golden Gate by the late
morning before spreading deeper southward and inland by the early
afternoon. Lighter post frontal showers will then persist through
the remainder of the day before mostly tapering off overnight
Saturday into Sunday. A few weak isolated showers could persist
into Sunday, but most locations should remain dry given the
limited coverage and intensity. Storm total rain from this system
should be highest across the North Bay, particularly the coastal
range, where up to 1.50 to 2.00" are possible The North Bay
valleys could see around 0.75 - 1.00" while locations farther
southward and inland will see progressively less, such as around
0.50" near San Francisco and Oakland and 0.25-0.33" near San Jose
and Monterey. Southerly winds will become breezy to occasionally
gusty through Saturday morning but are expected to remain below
wind advisory criteria throughout the storm system.

A muted warming and drying trend is forecast to occur on Monday
under weak high pressure aloft. This is trend ends abruptly as a
different storm system is set to impact the area on Tuesday.
Models agree this system will be weaker than previous storm
systems and move at a quick clip. Light rain accumulations are
expected through the day Tuesday, but may be enough to be a
nuisance for any outdoor events and rush hour commutes.

Dry conditions return for the tail end of the week from Wednesday
through Friday though models hint at another weak wet system
impacting the area next weekend.

&&

.AVIATION...as of 09:40 AM PST Friday...Mainly VFR conditions
this morning with scattered showers from the South Bay into the
Central coast which briefly lower to MVFR cigs/vsbys. Showers will
diminish by the afternoon with an increase in W-NW winds. Winds
diminish late this evening ahead of another weather system which
will bring stronger southerly winds, rain showers and lowering
ceilings to the Bay Area Saturday morning then latter in the day
over the Monterey Bay Terminals.

Vicinity of KSFO...VFR, W-NW wind near 15 knots occasionally gusting
to 20 to 25 knots through the evening. Wind becoming light and
variable then mainly light SE late tonight. VCSH possible late in
the night with more widespread coverage of -SHRA early Saturday
morning. Increased southerly winds with occasional gusts and rain
showers to continue on Saturday.

SFO Bridge Approach...Similar to KSFO.

Monterey Bay Terminals...VFR with scattered showers briefly
lowering cigs/vsbys this morning, W-NW winds 5 to 10 knots
becoming light SE tonight into Saturday morning. Rain showers
likely to return to the region after 18Z Saturday.

&&

.MARINE...as of 09:40 AM PST Friday...High pressure over the
eastern Pacific will weaken through Saturday and result in
diminishing winds tonight. A low pressure system will then arrive
from the northwest brining rain showers and locally gusty winds to
the coastal waters through the weekend. Another system will
arrive on Tuesday with stronger northwest winds and chances of
rain showers.
