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 Aug 14, 11:18 PM PDT, 3 hours 39 minutes earlier.
Area forecast discussion, Aug 14, 11:18 PM PDT, 3 hours 39 minutes before
Area Forecast Discussion
National Weather Service San Francisco Bay Area
1118 PM PDT Sat Aug 14 2021
.SYNOPSIS...As high pressure strengthens this weekend, Sunday should
be the hottest day for inland locations and higher elevations.
The weather pattern changes early next week providing the next
cooling trend for the Bay Area and Central Coast as an upper
trough tracks across NorCal.
&&
.DISCUSSION...as of 09:00 PM PDT Saturday...A lopsided synoptic
scale tug of war is underway with a broad 596dm monsoonal ridge
centered 400 miles east of the Bay Area and a weaker 586dm low
pressure disturbance focused 850 miles offshore to west. The
center point between these two features is roughly 300 miles
offshore, meaning that the broad monsoonal high pressure system is
responsible for the majority of our weather, but not all. That is,
the marine layer has been surprisingly robust this evening despite
the relatively high pressure aloft of the region. In fact, the
latest readings from the Fort Ord profiler show the marine layer
has been gradually deepening and is now around 1800 feet in depth
after depressing to below 1000 feet last night. So, what this mean
is that despite what is a very hot and dry for most across the
state, the majority of our region has been fairly seasonable and
dictated by the marine layer and robust onshore flow while only
the more remote locations of our forecast area such as Cloverdale,
Berryessa, Pinnacles, etc are experiencing the triple digit heat
much of the rest of the interior of the state is seeing today.
Otherwise, evening satellite imagery is quite dynamic and features
a number of interesting features, including a textbook tropical
hurricane system off Baja (Linda), decaying monsoonal
thunderstorms over the Sierra sending their remnants westward
towards our area this evening, omnipresent wildfire smoke, marine
stratus and even a band of tropical moisture farther offshore.
Convective models have hinted that some of these showers and
thunderstorms rolling off the Sierra in the mid level easterlies
could bring a few sprinkles to our region into the morning though
chances are rather slim. Per the smoke, air quality sensors
across the region are running in the yellow to orange range,
indicating that the stagnate air mass trapped under the high
pressure system is preventing fresher air from entraining into the
region. Unfortunately, even with the afternoon sea breezes, air
quality struggles to improve given the amount of smoke lingering
offshore waiting to be pushed inland. That said, HRRR smoke model
suggests an arriving trough later early in the work week will help
clear out the smoke and advect in fresher air.
Looking ahead, the high pressure system over the area will peak in
intensity tomorrow and very hot and dry conditions should be
anticipated across the interior regions. Essentially, areas that
were at least in the mid 80s today should expect another few
degrees of warming into tomorrow, while nearer shore areas will
see little difference. Robust onshore flow returns with tomorrow
evenings seabreeze. Interior locations just beyond our forecast
area will be flirting with record temperatures tomorrow and some
unofficial record heat along our periphery is also possible.
Needless to say, wildfire fuels are extremely dry so vigilance and
caution is advised for those choosing to spend time outdoors
tomorrow.
Then, on Monday, the aforementioned offshore disturbance and an
approaching Gulf of Alaska low will work together to suppress the
high pressure system currently stagnating over us this evening
before completely evicting it from the local region by Tuesday.
Remnants of the ridge will then spin offshore and form an eastern
Pacific high through the upcoming week while the broad 545dm low
sweeps across Canada and the upper to mid intermountain west. As
such, expect a trend towards a deeper marine layer and cooler and
wetter conditions. Confidence is rather high on this occurring
given that 5 of 5 ensemble clusters show similar scenarios playing
out between days 3 and 6 with only minor to moderate perturbations
in the low pressure intensity being different.
&&
.AVIATION...as of 11:18 PM PDT Saturday...For the 06z TAFs.
VFR/MVFR around SF Bay and LIFR around Monterey Bay terminals with
low CIGs. Marine layer has pushed into northern SF Bay and the
East Bay Hills, now covering KOAK and approaching KHWD. Latest
model solutions keep stratus mostly confined to these areas with
more patchy development around KSJC/KSFO in the early morning
hours. Some compression of the marine layer expected overnight as
high pressure strengthens over the area, limiting stratus coverage
away from the coast. Also noting HZ/FU reported at inland
terminals KCCR/KAPC/KSTS as smoke and particulates settle near the
surface, but VFR-level vis remains at the surface. Wildfire smoke
may continue to hinder slant range vis through the TAF period,
more so in North and East Bay.
Stratus clears tomorrow, early to mid-morning with onshore breezes
continuing in the afternoon/evening. Return of marine stratus in
the evening, but likely limited in coverage with more compressed
marine layer.
Vicinity of KSFO...VFR. Thick stratus observed on night satellite over
the coastal waters banked up against the coastal range, and
through the Golden Gate into North/East Bay. Possible low clouds
moving over the approach and terminal in the early morning hours,
but low confidence given recent model output. Light WNW winds
overnight into the early morning. Moderate seabreeze around 20 kt
returns in the afternoon.
KSFO Bridge Approach...Clear over the approach, at least through
11z-12z.
Monterey Bay...LIFR with stratus covering coastal areas and the
Salinas Valley. BR/FG developing overnight. Patchy light coastal
drizzle possible overnight and Sunday morning, as per certain hi-
res ensemble members. Conditions improving to MVFR-VFR mid to late
Sunday morning, with seabreeze returning in the afternoon. Marine
layer pushes inland Sunday evening with IFR/LIFR CIGs.
&&
.MARINE...as of 8:51 PM PDT Saturday...Surface high pressure over
the eastern Pacific will result in breezy northwest winds into
early next week. Coastal jets will set up along the Big Sur Coast
and Point Reyes. Additionally, gusty westerly winds will redevelop
from the Golden Gate to the Delta Sunday afternoon and evening.
These winds may be hazardous for smaller vessels. The sea state
continues to be driven by a weak southerly swells from the
remnants of a tropical system and a northwesterly swell stemming
from a low pressure system off the coast of British Columbia.
