.SYNOPSIS...
Issued at 112 PM PDT Tue Oct 8 2024

Expect gradual cooling across the forecast area that`ll extend
into the weekend. Temperatures will remain above normal until the
weekend. A Heat Advisory remains in effect until 7 pm this evening
for the East Bay Interior Valleys, Eastern Santa Clara Hills and
the East Bay Hills.

.SHORT TERM...
(This evening through Wednesday)
Issued at 135 PM PDT Tue Oct 8 2024

Farthest inland locations where it`ll still be hot today such as
the East Bay and the Eastern Santa Clara Hills are under a heat
advisory until 7 pm this evening. A modest 1.8 mb SFO-SAC pressure
gradient will otherwise result in afternoon and early evening sea-
breezes. Afternoon temperatures closer to the bays and the coast are
cooler to much cooler compared to Monday afternoon. Afternoon temps
are quite likely to fall short of today`s record highs at the long
term sites.

.LONG TERM...
(Wednesday night through next Monday)
Issued at 135 PM PDT Tue Oct 8 2024

A gradual cooling trend continues through mid to late week. By the
weekend temperatures will be near normal for the time of year. Dry
weather prevails this week, then a weakening 500 mb trough approaches
the forecast area with a slight chance to chance of light measurable
rain over the weekend.

.AVIATION...
(00Z TAFS)
Issued at 414 PM PDT Tue Oct 8 2024

Currently VFR at all terminals. The pattern is still very much
being dominated by a ridge of high pressure and a
compressed/shallow marine layer is to show for it. This will favor
sub-VFR conditions impacting terminals immediately adjacent to
the coast, with highest confidence at MRY, OAK, and SNS.

Vicinity of SFO...Currently VFR with westerly flow. Low to moderate
confidence on the terminal developing a ceiling overnight. The
marine layer depth of 1,000 feet is just on the cusp of whether or
not it is able to maneuver through the San Bruno Gap. If the
marine layer deepens overnight, there is a greater chance in
ceilings impacting the terminal in addition to an earlier
onset/longer duration, but if it stays as it is right now, stratus
will have to take the Golden Gate Gap trip which will result in a
late night/short duration event. Winds will prevail out of the
west through the TAF period.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Currently VFR with northwesterly flow at
both terminals. Moderate to high confidence on IFR conditions at
both terminals overnight with the possibility for further
deterioration to LIFR. VFR will prevail by tomorrow afternoon.

&&

.MARINE...
(Tonight through next Sunday)
Issued at 414 PM PDT Tue Oct 8 2024

Moderate to fresh northerly breezes persist through Wednesday,
particularly across coastal waters 10 to 60 nautical miles from
shore, gradually diminishing to a light breeze by Friday.
Moderate to at times fresh northwesterly swell continues to move
through the waters today, translating to hazardous boating
conditions for smaller vessels. Hazardous conditions are forecast
to persist through at least Friday. A passing storm system and
associated frontal boundary will bring the next opportunity for
rain with subdued winds and seas this weekend.
