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 Jul 20, 1:01 PM PDT, 1 hour 30 minutes earlier.
Area forecast discussion, Jul 20, 1:01 PM PDT, 1 hour 30 minutes before
Area Forecast Discussion
National Weather Service San Francisco Bay Area
101 PM PDT Tue Jul 20 2021
.SYNOPSIS....A seasonable July weather pattern will continue
through the rest of the work week with a marine layer in place
along the coast while clear conditions continue inland. The ridge
may weaken late in the weekend into early next week with some
increasing clouds as monsoon moisture rotates out of the Four
Corners region with temperatures near or slightly below normal by
early next week.
&&
.DISCUSSION...as of 1:01 PM PDT Tuesday...Plenty of sunshine
inland this afternoon but temperatures running several degrees
cooler than yesterday with moderate to strong onshore winds in
place. The SFO to Sac gradient is up to 3 mb with gusty west winds
forecast this afternoon through the Golden Gate and out into West
Delta where steady west winds are still blowing around 20 mph.
Along the coast the marine layer is around 1800 feet and likely
wont mix out at favored locations such as Pt Reyes, Ocean Beach
and the Monterey Peninsula as persistent northwest winds continue
to blow over the ocean. So as the synoptic pattern features a 558
dm low near the British Columbia coast with a 594 dm high over
the Four Corners the end result for the Bay Areas is a seasonable
onshore wind flow day with micro-climates showing themselves as
high struggle to reach 60 degrees at cloud shrouded beaches while
mid 90s are showing up for the interior valleys.
No reason to not expect the marine layer to surge inland again
this evening with a well defined inversion in place and moderate
to strong onshore gradients. The inversion height looks to stay
just below 2000 feet so coverage beyond SF Bay will be patchy by
Weds morning.
Day over day changes in the sensible weather look minimal Weds
through Friday as the synoptic pattern wont change too much as
onshore winds stay in place. Expect well defined marine layer with
night and morning low cloud and fog intrusions. No real hot
weather is forecast as temps should be fairly seasonal with places
like Livermore topping out it the lower 90s while Oakland sees
highs around 70 with 60 at the coast.
The flow aloft may turn more zonal by Saturday which could allow
for some increasing clouds by Sunday into Monday as residual
monsoonal moisture flows into California. At this time not
expecting any convection for the Bay Area/Central Coast but will
be watching closely for any deviation in the pattern. At this time
of year the overall weather pattern remains pretty static for the
Bay Area with monsoonal intrusions being one of the of the few
items that can lead to high impact breaks in the pattern.
&&
.AVIATION...as of 10:30 AM PDT Tuesday...For the 18z TAFs. A
robust marine layer remains in place at around 1,800 ft AGL per
the Fort Ord Profiler. Satellite imagery shows stratus along the
coast, through the Golden Gate Gap, and around the Monterey Bay.
Lingering IFR conditions around the Monterey Bay into later this
morning with VFR conditions expected elsewhere through this
evening. Low clouds are expected to return tonight (07z-10z) for
KAPC/KOAK with earlier returns for the Monterey Taf sites (02z-
04z). There is a chance for low clouds to move into KSFO late
tonight. Onshore winds increasing this afternoon to around 15 kt
with stronger gusts around KSFO. As an upper level trough to our
north deeps, winds will remain breezy through late tonight.
Similar clearing times anticipated for tomorrow.
Vicinity of KSFO...VFR through this evening with a slight chance
of low clouds intruding into the airport late tonight into early
tomorrow morning. Onshore winds forecast to increase this
afternoon to 15-20 kt with gusts of 25-30 kt. Winds may remain
breezy into late tonight before diminishing.
KSFO Bridge Approach...Similar to KSFO.
Monterey Bay...Low clouds are slowly retreating back towards the
coast this morning. IFR cigs may linger around KMRY the next hour
or so before VFR conditions are expected this afternoon. Expect
stratus to re-build early this evening and move down the Salinas
Valley tonight with IFR/LIFR conditions through mid to late
tomorrow morning. Patchy fog/drizzle possible again late tonight
into the early morning. Breezy onshore winds this afternoon around
10-15 kt with locally higher gusts down the Salinas Valley.
&&
.MARINE...as of 12:18 PM PDT Tuesday...Northwest winds will
increase across the waters today and tonight. The strongest gusts
are expected over the northern outer waters and along the Big Sur
coast. These winds will generate steep waves resulting in
hazardous seas conditions for smaller vessels. Also expected
stronger gusts to funnel through coastal gaps and the Golden Gate
into the San Francisco Bay in the afternoon and evening. Winds
will remain elevated through much of the work week. Seas remain
predominately wind driven with northwest waves at 8 to 10 seconds
along with a longer period light southerly swell.
