Area Forecast Discussion
National Weather Service San Francisco Bay Area
536 PM PDT Sun Jun 26 2022

.SYNOPSIS...Dry and generally seasonal weather conditions expected
through the forecast period. Continuing very warm to hot days farther
inland areas early this week, then gradual cooling. A marine layer
will continue along the coast with associated low clouds and patchy
fog progressing locally inland night and morning hours.

&&

.DISCUSSION...as of 02:50 PM PDT Sunday...After a little bit of a
roller coaster ride for the first half of June, the near term
weather is settling into more "June-like" conditions. Satellite
imagery this afternoon is almost a mirror image of Saturday -
widespread coastal stratus, inland sunshine, and cumulus popping
over the Sierra. Another typical June weather feature are large
temperature spreads across the forecast area. Current conditions
along the immediate coast are struggling to even reach 60 degrees
this afternoon, but interior locations are soaring into the low
100s. This is most prevalent in Monterey county with Big Sur
coastline in the upper 50s, but 10 miles inland is 103 at Arroyo
Seco.

Tonight through Monday: The stratus hugging the coast this
afternoon will move inland again tonight, especially SF Bay, N
Bay, and Salinas Valley. Similar to last night, patchy fog and
some drizzle will be possible along the coast. The most cooling
will occur below 1,200 feet with the hills remaining mild. Expect
a repeat for Monday - morning low clouds/patchy fog eroding back
to the coast mid-morning. Temperatures will once again be cooler
at the coast, but still dangerous heat across the far interior. A
Heat Advisory still remains in effect for the southern Salinas
Valley and interior San Benito through 10 PM for high to very high
Heat Risk.

Tuesday and beyond: The upper ridge that brought inland heat the
last few days finally gets pushed eastward as an usual (June
standards) upper level trough moves through NorCal Tuesday. The
passing upper trough will bring widespread cooling to the region,
especially the interior locations. Additionally, it`s possible the
trough may disrupt the marine layer limiting night/morning
stratus. Temperatures as whole will return to seasonal or slightly
below seasonal average by midweek and into next week. As noted on
other discussions - still need to keep an eye on tropical moisture
sneaking northward into CA late in the week as a tropical system
weakens.

.AVIATION...as of 5:24 PM PDT Sunday...For the 00Z TAFs. VFR into
the evening before lower clouds begin to fill into the bays and move
inland. Winds will  weaken into the night and remain light to
moderate through the mid to late morning. Expect IFR/LIFR conditions
for all but the more inland terminals, such as LVK and SJC stay VFR
into the night. Widespread VFR returns in mid to late Monday morning
followed by a breezy afternoon.


Vicinity of KSFO...VFR through the late night. Winds will stay
breezy until nightfall, then become more moderate. Lower clouds
will being filling around the SF Bay in the late night causing IFR
that will last into the mid morning. Expect a breezy Monday
afternoon with peak winds around 17 kts and gusts around 27 kts.
These breezy winds are expected to last into the night.

KSFO Bridge Approach...Similar to SFO.

Monterey Bay...Becoming IFR/LIFR in the evening and into the early
night. Winds will weaken through the evening and become light and
variable through the night. VFR is expected to return in the mid to
late morning. Winds become more moderate to breezy for the afternoon
before easing into the night once again.

&&

.MARINE...as of 05:35 PM PDT Sunday...Low clouds and fog will
dominate the coastal waters while winds  remain generally light
and a long period SW swell continues to  move through the waters.
Winds will be gusty around prominent  points and headlands and
through coastal gaps. Look for the swell to subside by Monday and
winds to increase out of the north  Monday night. This will bring
building short period steep seas for the balance of the work week.
