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 5, 11:23 AM PDT, 3 hours 15 minutes earlier.
Area forecast discussion, Aug 5, 11:23 AM PDT, 3 hours 15 minutes before
Area Forecast Discussion
National Weather Service San Francisco Bay Area
1123 AM PDT Thu Aug 5 2021
.SYNOPSIS...Patchy drizzle is being observed Thursday morning
along the immediate coastline. Onshore flow will increase Thursday
afternoon with the passage of a weak and dry front helping to
keep temperatures cool in the afternoon. Temperatures return to
seasonal norms on Friday leading into the weekend as the marine
layer returns each night.
&&
.DISCUSSION...as of 09:15 AM PDT Thursday... Synoptic scale
pattern features a 555dm Gulf of Alaska low nearing the shores
Juneau AK with a 580dm trough base swinging directly over the San
Francisco Bay Area this morning. The presence of the trough has
allowed the marine layer to deepen to roughly 2000 feet, providing
enough of a reservoir for the passing dynamic lift to couple with
orographic forcing to bring a coastal drizzlefest/light rain
event. Numerous locations along the coast and coastal facing
slopes have reported a few to several hundredths of an inch of
precipitation as a result.
This passing low pressure system will continue to sweep across
the region through the course of today and tomorrow before
exiting into the Great Basin early this weekend. Counterclockwise
flow around this features will cycle smoke from the fires in
northwest California towards our immediate area beginning today
offshore and through coastal gaps, and moreso throughout the
valleys of of the Bay Area beginning tomorrow morning. We will
continue to monitor the threat of this smoke and update
accordingly via social media.
No updates planned this morning, please view the previous
discussion for more details on the current forecast package.
.PREVIOUS DISCUSSION...as of 03:00 AM PDT Thursday...A dry air
mass aloft at just lower than 900 mb firmly sits over the Bay Area
and the Central Coast. The marine layer has deepened to
approximately 1800 feet as the result of an approaching upper
level trough. The trough currently sits out over the ocean due
west of Eureka, but will likely move over the coastline by 6 AM
LST. This trough has brought a localized weak vort max near the
Bay Area that has created some patchy drizzle along the immediate
coastline and isolated parts of the San Francisco Bay shoreline.
Drizzle has already been reported this morning from Oakland and
Downtown San Francisco, all the way down around the Monterey Bay
raging from just a trace to at most (currently) 0.04". Localized
wet roadways may be possible and the use of windshield wipers may
be helpful.
Temperatures were already cooler on Thursday and this previously
mentioned trough will keep temperatures on the cool side once again
with breezier onshore winds today. In fact a few areas situated just
east of coastal gaps, like KSFO, could even see a few stronger gusts
around 25 to 30 mph. By Friday, ensemble models are depicting the
trough to move eastward north of Salt Lake City changing the
prevailing wind pattern aloft to more zonal flow in nature. The
marine layer is expected to remain in place, but temperatures will
nudge upwards back to warmer, seasonal normal values over the
weekend.
Winds aloft in an upper level trough start northerly west of the
trough axis , then turn to west as it wraps around the southern
point of the trough, then southerly as it exits the trough. So as
this trough moves inland Thursday night into Friday, it can be
expected for the winds aloft to be northerly along the backside of
it. The impacts from this wind pattern is the chance for the smoke
from the currently burning wildfires in Northern California and
Southern Oregon could catch the current aloft and be pushed
southward toward the Bay Area. Both of the HRRR's Vertically
Integrated Smoke and Near-Surface Smoke brings the chance for smoke
to move southward over the North Bay and East Bay Hills. Please
refer to either the Bay Area Air Quality Management District or
Monterey Bay Air Resources District for more information.
By early next week, another short wave trough looks to move down the
Pacific coast before moving onshore. However, both GEFS and Euro
ensemble models are now depicting the trough to be weaker and remain
much farther north in the Pacific Northwest, compared to yesterday's
run that had it just barely reaching the North Bay. Ensembles
display a ridge aloft setting up over southern Nevada by midweek
which could bring a southerly onshore wind pattern back to the
region. Otherwise, the next week should be mostly quiet with
seasonal normal temperature values.
&&
.AVIATION...as of 11:23 AM PDT Thursday...For the 18z TAFs. Mixed
VFR/MVFR/IFR conditions across terminals, as stratus burnoff
continues through the morning. Satellite imagery reveals lingering
stratus along much of the coast and around SF Bay, with a steady
feed over the SF Peninsula and coastal San Mateo County. This will
allow low CIGs to persist around the Bay through around 20z. VFR
for the afternoon, with breezy to locally gusty onshore winds as a
trough of low pressure moves over NorCal. Upper winds around this
system will also transport smoke from NorCal wildfires down the
coast and over the Bay Area this afternoon. While smoke will
mostly stay aloft, it may affect slant-range visibilities upon
approach.
CIGs will move inland again tonight and into Friday morning,
though the absence of lower level cooling will preclude drizzle
for the most part.
Vicinity of KSFO...MVFR CIGs reported with bases reported around
1300 ft. CIGs will continue to lift and scatter through the
morning, bringing VFR conditions by 20z. Breezy onshore winds
currently 15-20 kt, becoming gusty this afternoon, 25-30 kt.
KSFO Bridge Approach...Approach is rapidly clearing, with few-sct
low clouds visible on satellite.
Monterey Bay...VFR/MVFR with FEW-SCT low clouds reported at
KMRY/KSNS but OVC010 at KWVI. SCT clouds may persist through the
afternoon along the coast. Moderately breezy to sometimes gusty
onshore winds will pick up this afternoon. Stratus returns this
evening bringing MVFR and later IFR/LIFR conditions at night.
&&
.MARINE...as of 9:04 AM PDT Thursday...Breezy northwest winds
will increase this afternoon and evening across the coastal
waters, creating hazardous conditions for smaller vessels. Gusty
afternoon and early evening west winds will also develop over the
San Francisco Bay north of the Bay Bridge and into the Delta.
Steep short period locally generated northwest waves at 5 to 7
seconds continue to dominate the sea state along with a moderate
period southerly swell.
