What forecasters said that day

The local office's own words before this gale warning 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 gale warning went out at Jun 30, 10:24 PM PDT, 4 hours 11 minutes earlier.

Area forecast discussion, Jun 30, 10:24 PM PDT, 4 hours 11 minutes before
Area Forecast Discussion
National Weather Service San Francisco CA
1024 PM PDT Sun Jun 30 2024

...New AVIATION, MARINE...

.SYNOPSIS...
Issued at 1235 PM PDT Sun Jun 30 2024

Significant warm up still on the way for next week after near normal
temperatures this weekend. Increased fire danger next week as well
with temperatures well above normal and dry conditions through next
weekend.

&&

.UPDATE...
Issued at 901 PM PDT Sun Jun 30 2024

Low marine stratus has begun to encroach on our coastal locations
and is expected to persist through mid/late morning tomorrow. No
significant change in the forecast for the impending heat wave
that will begin to ramp up on Tuesday. However, a Red Flag Warning
is now in effect for portions of the North Bay Interior Mountains,
East Bay Hills, Marin and Sonoma Coastal Ranges beginning
tomorrow night. Any activity that could cause an ignition should
be avoided, for example dragging trailer chains, unsecured
campfires and of course fireworks, the most obvious concern as we
move through the Fourth of July holiday and subsequent long
weekend. Another hazard more coincident with the timing of the
heat wave than the actual heat itself, is the potential for
flooding near the coast as we enter a New Moon phase. People
flocking to the water to try and escape the heat may encounter
more dangerous surf conditions than normal and potential road
closures where water spills over on to roadways.

&&

.SHORT TERM...
(This evening through Monday)
Issued at 1235 PM PDT Sun Jun 30 2024

A gorgeously warm day across the region today, and a great day to
be outside. Temps warm up a few degrees going into Monday as a
weak upper level trough degrades and moves inland. Highs Monday
look to be in the 90s across the interior, 80s for much of the Bay
shoreline, and 70s along coastal areas. If you live in the
interior, now is the time for any outdoor chores you may need to
get done before the warm up begins on Monday.

&&

.LONG TERM...
(Tuesday through next Saturday)
Issued at 1235 PM PDT Sun Jun 30 2024

Significant warmup really begins Tuesday as the very strong ridge
settles in across the West Coast. Not much change in the forecast
through the middle part of the week. Excessive Heat Warning goes
into effect Tuesday morning for interior areas, while lower
elevation locations that were once in the Watch have been
converted to a Heat Advisory given that they will cool off a
little more efficiently at night. Inland and high elevation areas
in the Warning will not see as much overnight relief through the
end of the week. Compressional heating under the ridge will warm
the airmass to near daily record territory above what little will
be left (if anything at all) of the marine layer. Guidance
continues to advertise 850 mb temps around 28 C, peaking
Wednesday. The daily max moving average this time of year is about
26.7 C, and we will be well above the 90th percentile, which is
about 23 C. Did nudge high and low temperatures up by a couple of
degrees Wednesday into the weekend as of this afternoon forecast
package. Far inland areas may actually end up with triple digits
into the weekend and the start of the next week. Left the timing
of the heat hazards as is for now (expiring Friday night), but
will definitely need to look into extending the Excessive Heat
Warning through the weekend. Cluster analysis still shows rather
high uncertainty regarding the breakdown of the ridge into next
week, hence the decision to wait on extending the hazards until
we become more confident over the next couple of days.

HEAT SAFETY AND IMPACTS:

By now you’re well aware that it is going to be extremely hot next
week with well-above normal temperatures; now lets talk about the
impacts of excessive heat and actions we can take to minimize those
impacts: With extreme heat, and especially prolonged heat events, it
is a marathon, and not a sprint. Our bodies, infrastructure, pets,
and livestock will be under duress from heat over the span of days
as opposed to just a day or two. Given that there is little
overnight relief expected throughout this event, this is where it
really becomes a marathon, and precautionary measures are
necessitated in order to prevent adverse results such as heat
exhaustion and stroke. This is not just for individuals sensitive to
heat, but rather, the entire population. Heat for this duration and
at these temperatures can be dangerous for everyone. Do your body a
favor and if you can, suspend outdoors activities between the hours
of 10am and 7pm on days where Excessive Heat Watches or Warnings are
in effect. Remain in air conditioning if you have that available to
you in your residence, or seek out air conditioned environments such
as stores, movie theaters, restaurants, libraries, and cooling
shelters.

If you cannot access air conditioned environments, must be outside,
work outdoors, or otherwise, there are other precautionary measures
you can take to keep yourself and your loved ones safe (including
pets!) during excessive heat. Take frequent breaks in the shade and
ensure that you are drinking plenty of cool water, or other
hydrating beverages such as sports drinks with electrolytes. Avoid
DEHYDRATING drinks such as alcohol or caffeinated beverages. That
aside, visiting your city public pool or a lake, river, or ocean
can also help keep you cool, but don’t forget the life jacket! If
planning on swimming, stick to where there is a lifeguard, and
know the ocean or river conditions before you get in. Although
outside of our area, its worth repeating: rivers can run fast and
cold with snowmelt in the Sierra Nevada mountains, and cold water
shock can set in quickly, which can lead to loss of muscle
control, and ultimately, drowning. Cold water shock can also set
in for ocean- goers. Have fun at the water, but be smart, be safe,
and Know Before You Go!

Finally, if you do not have air conditioning or cannot access it,
and also cannot access a body of water to stay cool: consider taking
cold showers or baths, turn on those sprinklers or garden hose and
have a fun time in your own makeshift “water park,” or lay a damp,
cool towel across your head or body. Even just dipping your hands
and feet in cool water can help to abate feelings of excessive heat.
For pets and livestock, make sure they have access to shade
structures or areas, and have clean water freely available to them
at all times. They do not have the same resources or ability to
notify of feeling heat-stressed as we do, so check in on them! If
they’re permanently outdoors, consider giving them a quick rinse-
down with the hose or set up misters, as the evaporation will help
to keep them cool as well.

.AVIATION...
(06Z TAFS)
Issued at 1023 PM PDT Sun Jun 30 2024

IFR-LIFR ceilings will persist at the immediate coast and into the
Monterey bay region through the night, with stratus retreating to
the coast Monday morning. Model output continues to insist on a
chance for stratus to flow over the San Mateo Peninsula and impact
SFO and OAK, but confidence remains low to moderate. Will monitor
the evolution of stratus in the region overnight. Breezy onshore
winds will develop Monday afternoon, continuing into the evening.
Marginal LLWS concerns continue during the overnight periods,
especially at the coast and in the North Bay.

Vicinity of SFO...Model output continues to insist on a chance for
stratus to flow over the San Mateo Peninsula and impact the terminal
tonight. The TAF remains VFR but confidence in that forecast is
decreasing as the marine layer is deepening. Will monitor through
the night. Breezy west-northwest winds will continue overnight,
building again Monday afternoon as gusts reach 20-25 knots.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...IFR-LIFR ceilings continue to impact the
terminals through the night, clearing late Monday morning. Breezy
northwest flow develops Monday afternoon, with stratus building
back into the coastal regions, including MRY, on Monday evening.

.MARINE...
(Tonight through next Saturday)
Issued at 1023 PM PDT Sun Jun 30 2024

Strong northwesterly breezes with occasional gale force gusts
continue over the northern waters. Fresh northwesterly breezes
continue over the central and southern waters. By Monday
afternoon, winds become northerly and gale force to near gale
force gusts become more widespread over the coastal waters as high
pressure builds. By mid to late week, winds will gradually weaken
and become moderate to fresh. Significant wave heights generally
build to 10-12 feet through mid-week before abating by the late
week. Portions of the northern outer coastal waters may see peak
wave heights between 12-16 feet through mid-week.

.FIRE WEATHER...
Issued at 901 PM PDT Sun Jun 30 2024

...A Red Flag Warning is in effect from Monday evening through
Tuesday evening for the East Bay Hills, Marin and Sonoma Coastal
Ranges, and the North Bay interior mountains Monday evening
through late Wednesday afternoon.

A Red Flag Warning has been added to the list of hazards along
with the Excessive Heat Warning which remains in place for most
of our interior locations, and a Heat Advisory for some locations
closer to the shoreline that may still see minimal influence of
the Marine Boundary Layer. Minimum RH values inland for the
upcoming week and beyond will mostly be in the teens, with some
single digit values in areas of higher elevation. Overnight RH
recover will be poor to non-existent as the heat wave persists
through the week, and potentially into next weekend. The hot and
dry conditions continue to move ERCs into the 70-80 percent range.
With the long holiday weekend, and the many outdoor activities
expected, people need to be careful with any campfires, and
fireworks should not be used. Any wildfire that ignites will have
the potential for rapid spread. Lightning is the only natural
ignition for wildfires and there are no thunderstorms in the
forecast.
