What forecasters said that day
The local office's own words before this gale warning 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 gale warning went out at Feb 18, 4:57 AM PST, 3 hours 46 minutes earlier.
Area forecast discussion, Feb 18, 4:57 AM PST, 3 hours 46 minutes before
Area Forecast Discussion
National Weather Service San Francisco Bay Area
457 AM PST Sun Feb 18 2018
.SYNOPSIS...Blustery and much colder weather conditions will develop
across the region today in wake of a strong frontal passage. Post
frontal shower will be possible over the Pacific and along the coast
late tonight into Monday morning with snow levels dropping to or
below 1,500 feet. Widespread freezing temperatures are then expected
for inland areas once winds subside Monday night into Tuesday
morning. Cool and unsettled weather is expected to persist through
the end of next week.
&&
.DISCUSSION...as of 03:21 AM PST Sunday...A potent mid/upper
level low pressure system is currently dropping southward into the
Pacific Northwest early this morning. As this system progresses
southward, a strong cold front will push through the San Francisco
Bay Area later this morning and through the Central Coast by
early afternoon. As a result, blustery conditions are forecast
across the entire region this afternoon with daytime temperatures
a good 10 to 20 degrees cooler compared to yesterday. West-
northwest winds will become breezy to locally gusty, especially
along coastal areas where wind gusts of 40 MPH will be possible.
Mainly dry weather conditions are forecast with the frontal
passage, aside from a slight potential for isolated showers in the
coastal hills.
As the upper level trough continues to dig to the south, a very cold
air mass will advect southward across the region late tonight into
Monday morning. The forecast models continue to show post frontal
showers developing over the Pacific and along coastal areas from
late tonight into Monday morning as well. While widespread
precipitation is unlikely, snow levels will fall to or below 1,500
by tonight and potentially as low as 1,000 feet Monday morning.
Thus, the chances for accumulating snowfall have increased for the
Santa Cruz and Santa Lucia Mountains from late this evening into
Monday morning. The latest high-resolution models indicate the
potential for 1-3" in the Santa Cruz Mountains with the highest
elevations picking up nearly 5". Meanwhile, the Santa Lucia
Mountains will likely receive the greatest snowfall where 2-6" will
be more likely with isolated amounts upwards of 8". A dusting to
light snowfall amounts will also be possible over portions of the
North Bay Mountains, East Bay Hill as well as the Diablo and
Gabilan Ranges if showers become more widespread. Light rain
showers are also likely to impact portions of the Central Coast
including the Monterey Peninsula from late this evening into
Monday morning. Given 850MB temperatures forecast to drop below -5
deg C across much of the region, cannot rule out rain/snow mix
even at sea level. Any wintry precipitation will make traveling
extremely hazardous tonight into Monday morning. Thus, folks are
urged to drive with extreme caution if traveling.
Aforementioned breezy conditions are forecast to subside Monday
night into Tuesday morning as a very cold air mass settles in over
the region. Thus, look for widespread freezing temperatures inland
with frost possible all the way to the coast. Forecast temperatures
are expected to fall into the 20s for the coldest inland valleys and
higher elevations with lower 30s likely elsewhere. These conditions
will likely be the coldest the region has experienced in years. A
Freeze Watch remains in effect for inland areas Monday night into
Tuesday morning. While the cold air mass is forecast to remain in
place through midweek, the latest models show another mid/upper
level short- wave dropping southward across the region by
Wednesday morning. This would bring an increase in cloud cover
region-wide and very slight potential for precipitation to the
northern portion of the region. If this does occur, temperatures
would likely moderate enough to prevent another widespread freeze
across the region Tuesday night into Wednesday morning (which was
previously forecast to be the coldest night under a clear sky).
Thus, forecast confidence remains low and folks are encouraged to
stay up-to-date with the latest forecast information.
Medium range models maintain a cool and unsettled pattern over much
of the West Coast through late week and into next weekend. However,
there are difference in the solutions during this time frame with
respect to chances of precipitation and exactly how cool/cold
temperatures will be as weak systems pass over the region. Thus,
will need to closely monitor conditions in the coming days.
&&
.AVIATION...As of 4:57 AM PST Sunday...An approaching cold front
has resulted in the development of local MVFR and IFR cigs along
the coast, over the East Bay and South Bay and into the Salinas
Valley. Elsewhere it's VFR. The cold front is steeply sloped with
north-northwest winds pushing it southward to the north Central
Coast by 18z this morning. Skies will trend toward VFR and winds
will become gusty from the west-northwest. Both winds today into
Monday as well as a chance of rain and snow showers late tonight
into Monday will be primarily due to increasing boundary layer
instability. The SFO-SAC pressure gradient will reach nearly 4 mb
this afternoon, but the ACV-SFO gradient is forecast to remain
nearly flat today into Monday morning then increasing to nearly 6
mb later Monday afternoon. The coldest air in many years will be
ushered in beginning today, freezing levels will lower substantially
today through Monday.
Vicinity of KSFO...MVFR cig forecast to hold til 17z though latest
satellite imagery shows partial clearing in the vicinity of KSFO.
May need to amend toward scattered clouds depending how the cloud
cover behaves. West winds 20 to 30 knots, possibly a few higher gusts
at times today into this evening.
SFO Bridge Approach...Similar to KSFO.
Monterey Bay Terminals...IFR cigs this morning lifting to MVFR
cigs later this morning. Gusty west-northwest winds today. Tempo
clearing of cigs, but cigs will return this evening and overnight
leading to instability showers of rain possibly snow toward 12z
Monday and thereafter. The 06z NAM model forecasts the -8C 850 mb
isotherm over the Monterey Peninsula Monday morning, that's
impressively cold for this area, supportive of snow precip-type
at sea level.

.MARINE...as of 3:21 AM PST Sunday...Gusty northerly winds will
push a cold front southward over the California coastal waters and
bays this morning ushering in the beginning of what will be the
coldest air felt in many years. The wind chill will make it feel
like it's in the 20s over the coastal waters and bays later today
into Monday night. Instability will result in gusty northwest winds
and a chance of rain and snow showers. Gusty winds will generate
fresh swell and steep wind waves. Another cold front will swiftly
move southward over the coastal waters late Wednesday night reinforcing
the cold air through late this week.

This cold front will potentially result in the following weather hazards: * Locally strong and gusty west to northwest winds from Sunday afternoon through Monday. The strongest winds are expected near the coast where wind gusts up to 40 mph are possible. At this time winds are expected to remain just below wind advisory levels except perhaps at a few isolated windy spots along the coast. * Most forecast models indicate the potential for post-frontal showers across portions of the region from Sunday night into Monday, mainly along coastal areas and in the Santa Cruz Mountains and Santa Lucia Mountains. Snow levels are forecast to drop as low as 1,500 feet on Sunday night and as low as 1,000 feet on Monday, or perhaps even lower. The greatest potential for snow accumulation will be in the Santa Cruz Mountains where 1 to 3 inches of snow accumulation is possible, and in the Santa Lucia Mountains of northwest Monterey County where 2 to 6 inches of snowfall will be possible. Winter Weather Advisories may be issued once forecast confidence increases regarding snow amounts. All other mountain areas including the North Bay Mountains and East Bay Hills are expected to see no precipitation or just a dusting of snow. * In wake of the frontal passage, one of the coldest air masses in recent years will settle in over the region. As winds subside Monday night into Tuesday morning, overnight temperatures will likely fall below freezing across most inland areas and potentially even in some coastal locations. A Freeze Watch is in effect for all inland portions of the San Francisco and Monterey Bay Areas late Monday night into Tuesday morning. Earlier it appeared that Tuesday night could be as cold, or even colder, as Monday night. However, recent models indicate that cloud cover will increase on Tuesday night ahead of another incoming weather system. That cloud cover should result in moderating temperatures on Tuesday night, except perhaps for the far southern portion of the region.
