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 7, 12:37 AM PDT, 2 hours 9 minutes earlier.
Area forecast discussion, Aug 7, 12:37 AM PDT, 2 hours 9 minutes before
Area Forecast Discussion
National Weather Service San Francisco Bay Area
1237 AM PDT Sat Aug 7 2021
.SYNOPSIS...Smoke from fires in Siskiyou and Trinity counties
has drifted into the Bay Area today and will continue to impact
the area into tomorrow. Onshore flow during the afternoon and
evenings should help improve air quality. Otherwise, warmer and
drier today with above normal temperatures regionwide. Gradually
cooler and wetter conditions over the coming days and into early
next week, then, warmer and drier late next week.
&&
.DISCUSSION...as of 9:48 PM PDT Friday...Forecast is on track,
only update was to add patchy light drizzle for the coastline
tonight/morning and Saturday night/morning. The marine layer will
remain compressed to 800 to 1,000 feet overnight and fog mixing
with smoke may result in potential dense fog or smog forming
overnight and Saturday morning. For more info please see the
previous discussion.
From previous forecast discussion: So, when will the smoke
situation improve? Well, we have a couple of items in our favor
that should lead to gradually improving conditions over time,
particularly by tomorrow's seabreeze. The first, is that the
transport winds that originally brought this smoke into the region
are weaker and less capable to transport an additional round of
smoke towards us in the coming days, so we mainly will be
contending with what is already here. Second, the onshore
seabreeze should strengthen between today and tomorrow, with the
HRRR smoke model suggesting a majority of the smoke evacuating
from the region through the peak of the seabreeze early tomorrow
evening. That said, pockets of smoke are still possible beyond
this, though for most, conditions should improve by then. Latest
indication is that things may continue to worsen for some until
3-4PM today when the afternoon seabreeze begins to reach its full
strength, and then improving conditions through the rest of day
and into the evening. This lesser smoke intrusion should be a
reminder for all in the area to prepare for what is likely to be
another active fire season and to prepare accordingly. As winds
shift from predominately onshore during the summer to more often
offshore by the fall, it is more likely to see smoke transported
towards our area.
Otherwise, today is significantly warmer than yesterday and one of
the rare summer 2021 days where most locations are warmer than
normal (+3-10 degrees). This is partly due to the aforementioned
drier air entrained into the region yesterday as drier air is
easier to warm and also because the cooling marine layer was less
resilient today. The other contributing factor is that high
pressure to our south expanded closer towards us today, advecting
warmer air towards the region, while also further suppressing the
marine layer.
Looking ahead, smoke aside, each of the next several days into
early next week should feature progressively cooler and less dry
conditions. This is due to the high pressure ridge to the south
retreating in favor of a passing trough to the north. Seasonable
to warmer conditions are then possible through most of next week
in response to building high pressure along our periphery.
&&
.AVIATION...as of 11:45 PM PDT Friday...For the 06z TAFs. Stratus
has moved onshore for the Monterey Bay Area, Up the SF Delta, and
down the Salinas Valley. The marine layer is around 1000ft
tonight, which will keep it closer to the coastal terminals. FG/BR
formation is possible in the North Bay early this morning. Light
DZ is also possible along the coast this morning. Typical onshore
winds for Saturday afternoon. Stratus should clear later in the
morning hours for most terminals. There will be elevated FU, which
could lead to some -HZ in the afternoon for inland and higher
terrain terminals (KLVK/KSTS/KAPC). This wildfire FU will reduce
slant range visibilities through the period. Stratus will return
Saturday night for most terminals that saw it today.
Vicinity of KSFO...VFR through 9-10Z, dropping to IFR around 10Z.
West wind through the period which should help bring back VFR to
SFO by late morning Saturday. More stratus returning later
Saturday night.
KSFO Bridge Approach...Similar to KSFO.
Monterey Bay...IFR/LIFR ceilings through 17-18Z. Light patchy
DZ & FG possible late tonight and Saturday morning. Conditions
improving to MVFR-VFR late Saturday morning and afternoon. IFR
cigs/vsbys due to stratus and fog returning Saturday evening and
night.
&&
.MARINE...as of 11:48 PM PDT Friday...Breezy to locally gusty
northwest winds continuing across the coastal waters through this
evening except winds diminishing over the southern inner waters.
Gusty northwest winds continuing over the northern waters
Saturday, winds decreasing elsewhere. The sea state remains
dominated by steep short period northwest waves at 6 to 8 seconds
along with a moderate period southerly swell.
