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 13, 11:29 AM PDT, 3 hours 13 minutes earlier.
Area forecast discussion, Jul 13, 11:29 AM PDT, 3 hours 13 minutes before
Area Forecast Discussion
National Weather Service San Francisco Bay Area
1129 AM PDT Tue Jul 13 2021
.SYNOPSIS...A seasonable weather pattern with temperatures running
near normal the rest of the work week and into the weekend. Night
and morning low clouds and fog will retreat to the coast afternoon
and early evening hours.
&&
.DISCUSSION...as of 9:38 AM PDT Tuesday...Forecast is on track
this morning with marine layer deepening to just above 2000 feet.
Noting some slightly cooler temps and higher humidity for the
hills between 2000-2500 feet. Some patchy drizzle reported this
morning with a few sites reporting 0.01 along the San Mateo coast
and even into the East Bay hills. Low clouds starting to erode and
should peel back to the beaches by lunchtime. Keeping an eye on
some monsoonal moisture that moved into the CA deserts overnight.
Closest lightning strike early this morning was near the Kern/SLO
county line. A few debris clouds approaching southern Monterey/San
Benito county line this morning but all impacts should stay to
our east with increasing southwest flow.
No appreciable short term weather changes with general trend of
cooling as onshore flow and weak cyclonic flow aloft develop for
the second half of the work week. In general a typical mid July
weather pattern looks to be setting up for the Bay Area.
Long range focus by early next week will be on 600 dm high over
Wyoming as a strong trough sets up off the PacNW coast. Will be on
the lookout for any possible convective intrusions into the
region for early next week.
&&
.AVIATION...as of 11:00 AM PDT Tuesday...For the 18z TAFs.
Currently, stratus has been scattering out and lifting around most
of the inland terminals. Ceilings will continue to improve around
the Bay area and KAPC for the next hour, becoming VFR by 19/20Z.
Onshore breezes will strengthen this afternoon, giving coastal
terminals moderately breezy winds. Stratus will push back in
tonight. The marine layer is around 2000ft today, with heights
persisting through the TAF period. More MVFR/IFR ceilings for terminals,
with the chances of -DZ around coastal terminals. A good chance
KLVK/KAPC seeing only MVFR skies. Light and locally driven winds
tonight. Skies should lift and clear Wednesday from 16-19Z.
Vicinity of KSFO... Skies clearing up to VFR within the next
hour. Increasing onshore winds in the afternoon with gusts around
20-25 kt. Stratus will return around 03Z with MVFR/IFR ceilings.
KSFO Bridge Approach...Similar to KSFO.
Monterey Bay... MVFR/IFR conditions will likely last through the
period for KMRY. Onshore winds this afternoon around 10-15 kt.
KSNS will see brief VFR ceilings from 20Z-02Z, but will see a
similar return to IFR ceilings tonight. Skies will remain IFR/MVFR
through early Wednesday morning.
&&
.MARINE...as of 09:16 AM PDT Tuesday...Northwest winds will
diminish across much of the waters today leaving light to locally
moderate conditions. Gusty northwest winds will persist over the
northern outer waters through the forecast period. Additionally,
expect breezy conditions this afternoon and evening around the
Golden Gate gap and northward through the Delta. Winds will
increase across the outer waters late this week. Sea state
remains predominately wind driven producing steep northwest waves
at periods of 8 to 10 seconds along with a light southwest swell.
