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 28, 10:31 PM PDT, 4 hours 2 minutes earlier.
Area forecast discussion, Aug 28, 10:31 PM PDT, 4 hours 2 minutes before
Area Forecast Discussion
National Weather Service San Francisco Bay Area
1031 PM PDT Sat Aug 28 2021
.SYNOPSIS...A marine stratus southerly surge has begun but will
likely not bring much relief until tomorrow night for most.
Sunday remains hazy with above normal temperatures through
midday. Then, the weather pattern will shift beginning tomorrow
evening that will bring cooler conditions with higher humidity, as
well as cleaner air through at least midweek.
&&
.DISCUSSION...as of 08:53 PM PDT Saturday... The peripheries of
the Eastern Pacific and Four Corners high pressure systems have
temporarily merged over California today, leading to further
warming and drying over yesterdays parched conditions. The latest
00Z KOAK sounding indicates 850MB temperatures have warmed to
nearly 25C, roughly on par with previous model data, though some
interior locations were likely closer to 26-27C. As a result,
surface temperatures rose an additional 2-5F over yesterday's
readings today and put many interior locations just under record
values for the day. Triple digit temperatures were officially
recorded in Santa Rosa, Napa, Livermore, Concord, Gilroy,
Pinnacles, and Parkfield today with a numerous other interior
unofficial sensors reporting similarly high conditions. Even some
coastal locations saw increases today as Monterey and San
Francisco both hit 84.
In addition, the high pressure over the region has forced the air
mass to become stagnant, ideal for both the dispersal of wildfire
smoke over a broad area and trapping it over an area. The weaker
marine inversion and stronger subsidence aloft has also forced
more of this suspended smoke to descend to the lowest levels of
the atmosphere, leading to locally poor air qualities and
potentially hazardous conditions for sensitive groups. Be sure to
follow your local air quality district for the latest on Spare the
Air alerts in effect. More on when the air qualities improves
farther below.
Smoke aside, evening satellite imagery depicts a southerly surge
reversal underway as the SFO-SMX gradient steepened from -1.3MB
to -2.5MB over the last 24 hours. Cloud ceilings range in the 200-600
foot range where the southerly surge is already inundating the
Monterey Bay coast with low hanging marine stratus. HREF model
indicates a 40% chance of the southerly surge making it to the
Golden Gate gap by tomorrow morning, which lines up closely with
its current trajectory (5mph, 50 miles from the gap, 10 hours
out as of 9pm). That said, an inundation of the marine stratus
inland while the high pressure is still in place will be limited
as the marine deck is compressed below 1000 feet. For locations
along the immediate coast, much cooler and less dry conditions
have arrived and should remain in place through the coming days.
These southerly surge reversals are very usual on the tail end of
at least 2-3 days of heat across the interior of California. The
large coast to interior thermal gradients during heat wave events
interior inspire their arrival. Most interior locations will
remain out of reach or above the fledgling marine layer and remain
rather dry again tonight. Higher elevation locations will also
remain warm with poor to no overnight humidity recoveries for one
final night.
Looking ahead, tomorrow is anticipated to be a stepwise
transition day with warm and dry conditions across the interior
through midday before the pattern begins to shift from high to low
pressure influences. By tomorrow PM, a broad low pressure system
descending southward from British Columbia towards California will
separate the aforementioned merged high pressure systems (East
Pac & Four Corners) and invoke a trend towards a cooler, wetter,
onshore, marine focused regime. Thus, tomorrow will still be on
the warm and dry side for most through the hours of peak heating,
with a shift towards stronger onshore flow by the late afternoon
to evening. Much deeper onshore flow and a return to near normal
conditions (below normal for coastal areas) arrives by Monday as
the trough descends deeper into California. Further cooling and
moistening persists into the midweek. In addition to cooler,
windier, and less dry conditions, onshore winds and a change of
air mass will together bring improved air quality for most
locations over the coming days (though air quality will likely
remain poor through at least midday Sunday for most). &&
.AVIATION...as of 10:31 PM PDT Saturday...For the 06z TAFs. A
southerly surge of stratus clouds is moving over the ocean
estimated to reach the Golden Gate between 12Z to 14Z. FEW low
clouds may develop in the Bay Area, but VFR conditions are
expected through the night as onshore winds diminish. Meanwhile
terminals around the Monterey Bay area already IFR/LIFR with a
chance for patchy fog and VLIFR conditions to develop early Sunday
morning. As the SFO-ACV gradient weakens, stratus will continue
to grow over the ocean, but VFR skies will return Sunday afternoon
as temperatures rise. Winds will be breezy with an occasional
stronger gust through the coastal gaps. Smoke remains around the
Bay Area for hazy skies, but onshore flow increases helping abate
the amount of smoke in the region. Increasing confidence for
stratus to make an inland push Sunday night. Forecast calls for
IFR cigs at many terminals, but it will be greatly determined by
how much the marine layer grows.
Vicinity of KSFO...Winds are still breezy currently, but are
forecast to gradually diminish through the night. Skies will
remain clear, but vis will still fluctuate do to the smoke still
lingering about. Onshore flow increases on Sunday afternoon
helping to improve vis concerns as peak afternoon winds reach up
to 20 knots. A few clouds may crop up around 12Z, but no impacts
are expected tonight. But with a more robust marine layer, clouds
will likely move into the East Bay Sunday night into Monday
morning. Lower IFR cigs may hover near the terminal, but for now
not expecting impacts directly over the terminals.
KSFO Bridge Approach...Similar to KSFO.
Monterey Bay...LIFR. Low clouds and patchy fog are expected into
Sunday morning with light winds. Clearing is expected by 16Z for
VFR skies and an onshore seabreeze. With a more definer marine
layer, stratus clouds will likely move back into Sunday night for
IFR/LIFR cigs.
&&
.FIRE WEATHER...as of 3:15 AM PDT Saturday...As stated in prior
fire weather discussions, the warming and drying trend this
weekend will help dry out fine fuels with ERC values expected to
slowly rise back towards the 97th percentile. Areas of greatest
concern are the hills since higher elevations won't have much of a
night time humidity recovery this weekend. The marine layer will
likely hover between 500 to 800 feet deep this weekend, so it
won't bring much moisture inland and any elevations above the
marine layer will stay fairly dry.
Although we will see some northerly winds, primarily in the
northeast Napa hills as dry north winds come down the Sac Valley
and spread out over the Bay Area, this isn't a classic, widespread
offshore wind event. Period of strongest winds looks to be early
Saturday morning across the North Bay, especially the Napa hills
with peak gusts around 20 to 25 mph. The lack of any moderate to
strong winds will preclude red flag conditions. However the
combination of extremely dry fuels, ongoing drought, low humidity,
lack of humidity recovery and hot temps will put us into near
critical fire weather conditions right through the weekend.
As the ridge breaks down expect a stronger seabreeze near the
coast Sunday afternoon then stronger onshore winds by Monday that
will precede better humidity recovery and a lag in the fine
fuels. As September looms we'll be on the lookout for offshore
wind events but for now warm and dry weather will be the main fire
weather element to watch on-top of the current drought stressed
fuels.
&&
.MARINE...as of 09:20 PM PDT Saturday...Breezy northwest winds
will continue over the northern outer waters with lighter winds
elsewhere through the rest of the weekend. Gusty westerly winds
expected Sunday afternoon and evening near the Golden Gate gap.
Winds will increase across the northern outer waters early next
week with near gale force gusts. Sea state remains driven by short
period northwest waves at 8 to 10 seconds along with a light
longer period southerly swell.
