...New SYNOPSIS, SHORT TERM, LONG TERM, MARINE...

.SYNOPSIS...
Issued at 335 AM PDT Mon Jun 23 2025

Quiet and seasonable weather is expected this week. Look for the
stratus to settle in at night with the marine layer deeming and then
mixing out for inland areas each afternoon. Minor coastal flooding
is also expected each evening through Thursday along the San
Francisco Bay.

&&

.SHORT TERM...
(Today and tonight)
Issued at 335 AM PDT Mon Jun 23 2025

Upper level troughing will sink into central and southern CA today
with weak upper level ridging sliding down the OR coast into
northwest CA. The main story will be the development of the stratus.
It has blossomed this morning and now spans the Central Coast and
filling in over the waters and the Bay Area coastline. Expect this
to solidify throughout the day, with cloudy skies for those near the
coast and sunny skies for those inland. Tonight the stratus will
penetrate inland, leading to cloudy skies for interior valley
locations.


&&

.LONG TERM...
(Tuesday through Sunday)
Issued at 335 AM PDT Mon Jun 23 2025

Little to no change to the extended forecast as upper level
troughing eventually gives way to quasi-zonal flow. This will lead to
cloudy nights with the stratus attempting to surge inland each time.
Any interior clouds are expected to mix out by the afternoon, giving
way sunny skies. Onshore flow continues, with the traditional gusty
afternoon and early evening hours. Temperatures will gradually warm
through the week and into the weekend, especially for interior
locations.

.AVIATION...
(06Z TAFS)
Issued at 1013 PM PDT Sun Jun 22 2025

CIGs are building along the coast affecting HAF, SNS, and MRY.
These CIGs look to fall to IFR levels overnight. Moderate to
breezy winds last through much of the evening before reducing into
the night. Expect mostly light to moderate winds through the late
morning and early afternoon on Monday. CIGs at MRY and SNS look
to have some moments of clearing overnight from an eddy in the
Monterey Bay, but CIGs look to mostly prevail until the mid to
late morning before eroding and getting back to VFR. HAF looks to
keep CIGs through the TAF period. Expect another round of moderate
to breezy winds again for Monday afternoon that will linger into
that evening. Monday evening and overnight shows strong potential
for a stronger marine stratus push, leading to more TAF sites
seeing IFR CIGs for that night.

Vicinity of SFO...VFR lasts through Monday evening. Breezy winds
last into the early night before gusts cut off and winds become
moderate. Expect a few moments of thin clouds to move through the
San Bruno Gap overnight, but not enough to fill over the terminal.
Breezy winds return Monday afternoon and last into that evening
before becoming light as IFR CIGs build.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...MVFR and IFR CIGs are filling around the
Monterey Bay. CIGs lower to IFR levels into the night. An otter
eddy forms in the middle of the Monterey Bay overnight, which
could lead to pulling and pushing of CIGs and fairly short periods
of scattering/clearing over the terminals. VFR conditions return
in the mid to late morning as CIGs erode and winds become more
moderate. Winds reduce into Monday evening as IFR CIGs return.

&&

.MARINE...
(Today through Saturday)
Issued at 335 AM PDT Mon Jun 23 2025

Fresh to strong northwesterly breezes will prevail through the
week. Seas will ebb and flow between moderate and rough through
the week.
