What forecasters said that day
The local office's own words before this wind 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 wind advisory went out at Jan 27, 10:02 PM PST, 4 hours 16 minutes earlier.
Area forecast discussion, Jan 27, 10:02 PM PST, 4 hours 16 minutes before
Area Forecast Discussion
National Weather Service San Francisco Bay Area
1002 PM PST Fri Jan 27 2023
.SYNOPSIS...Cooling trend continues into the weekend, with well
below normal temperatures then persisting through the first part
of next week. An upper level disturbance will bring some showers
Sunday and Sunday evening, especially to the southern half of our
area. Snow levels will be low, locally down to 2500 ft or even a
bit lower. In the colder air mass behind it, low temperatures
Monday and Tuesday mornings look to be very chilly. Widespread
freezes are then likely away from the coast, potentially even
touching some coastal areas.
&&
.DISCUSSION...as of 09:02 PM PST Friday...Another calm evening is
in the books with temperatures beginning to plateau in the lower
50s and mid 40s. Lower clouds have moved on shore around the SF
and Monterey Bays as well as the San Mateo Coast, while other
areas remain clear.
There isn't much to add from the previous forecast discussion below.
The forecasting team is keeping an eye on light rain over the
weekend, followed by hazardously cold overnight lows into the next
work week. Expect only minor adjustments as forecast confidence
continues to increase.
&&
.PREV DISCUSSION...as of 03:15 PM PST Friday...Latest satellite
imagery shows mostly clear skies over our area, aside from areas
of stratus along the coast from around Half Moon Bay northward and
some high cloudiness passing through from the north. Temperatures
around the Bays are running 5 to 10 degs cooler than yesterday,
reflecting the end of our recent period of offshore flow and
associated compressional warming. The pressure gradient from KSFO
to KWMC is now +2.9 mb in contrast to -5.5 mb 24 hours ago.
We're for a bit of a change in our weather over the weekend and
into next week. The large scale upper level high centered offshore
from the Pacific Northwest is forecast to build strongly northward
towards Alaska. That in turn will enable a strong but moisture-
limited upper level disturbance to travel rapidly southward from
the interior of northwestern Canada down through California. In
stark contrast to our extraordinary recent period of wet weather,
this is the sort of synoptic scale pattern that's more classically
associated with "La Nina" winters.
For tonight through Saturday night...Cooling of the air mass
aloft and deepening of the boundary layer ahead of the approaching
disturbance will result in some increase in night and morning low
cloud and fog coverage along with a few degrees of additional
reduction in afternoon temperatures. Highs tomorrow around the
Bays look to be largely confined to the mid and upper 50s.
More dramatic cooling is expected for Sunday as the approaching
"inside slider" upper level system moves in, with max temps
looking to be confined to the lower 50s at lower elevations and
40s in the hills. Although associated moisture will be limited by
its inland trajectory, nonetheless looks to be sufficient for
showers to develop during the day, especially over the southern
half of our area where some additional influx of low-level
moisture looks to occur.
Want to note a few other things about our weather on Sunday. Snow
levels look to get down to around 2,500 ft, and potentially even
locally a bit lower in any heavier showers. Also looks like there
could be just enough CAPE for some convection from around the
Santa Cruz Mtns southward, though very low topped; probably no
more than to 13 to 15 kft. But that could be sufficient to produce
some small and even an outside chance of lightning. Expect precip
totals to generally be no more than a trace in the North Bay and a
few hundredths of an inch in the heart of the Bay Area, but
potentially up to 1/4 inch in the Santa Cruz Mtns and Monterey
Peninsula area, and locally 1/2 inch in the Santa Lucia Mtns of
Monterey County.
Then starting Sunday night into Monday morning, it gets really
cold. A Freeze Watch has now been issued for virtually all of our
area for late Sunday night into Monday morning (see SFONPWMTR).
Widespread sub-freezing temperatures then look possible, and then
again Monday night into Tuesday morning which could potentially be
even colder. And it will remain chilly in the daytime, with highs
confined to the lower to mid 50s.
In the extended...temperatures slowly moderate with dry conditions
looking to prevail until rain chances return late in the week.
&&
.AVIATION...as of 9:57 PM PST Friday...For the 06Z TAFs. A mix of
VFR/MVFR/IFR as patchy stratus has formed in the hills around SF
Bay, coastal Monterey Bay and parts of the Salinas Valley. Hi-res
models project patchy stratus will continue through the night,
with the potential to spread to most terminals. Not seeing any
signs of valley fog, but the potential is there for the early
morning hours. Winds have weakened and will be light overnight.
Stratus clears by mid to late morning, and winds will be onshore
in the afternoon.
Vicinity of KSFO...VFR at area terminals, but stratus is observed
over the coastal and East Bay hills. Greater potential for impacts
to East Bay and South Bay terminals overnight, with IFR/MVFR cigs.
Light winds overnight. Clouds clearing by late morning with VFR
through the end of the TAF period. Winds becoming breezy late Saturday
night with an approaching trough from the north.
KSFO Bridge Approach...Mostly clear skies observed over the
approach. Low clouds may develop overnight, but currently low
confidence in cig development.
Monterey Bay...VFR/MVFR/IFR under patchy stratus at this hour.
Low to moderate confidence in low clouds lingering through the
morning. VFR Saturday afternoon with moderate onshore winds.
&&
.MARINE...as of 08:47 PM PST Friday...Strong northerly winds this
evening with near gale to gale force gusts, especially in the
outer waters north of Pigeon Point. Winds diminish this evening,
but remain hazardous for small craft, then increase tomorrow
night. Long period northwesterly swell has also arrived and will
continue to fill the waters through the weekend before slowly
diminishing. Light rain is in the forecast for Sunday as a weak
cold front pass over the waters.
