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

.SYNOPSIS...
Issued at 153 PM PDT Sun Jun 8 2025

Fairly quiet conditions this week, with the marine layer making
additional appearances for at least another night or two.
Temperatures will generally be near their seasonal averages this
week, though interior temperatures might rise a few degrees each day
before moderating some late into the week and weekend.
&&

.SHORT TERM...
(This evening through Monday)
Issued at 153 PM PDT Sun Jun 8 2025

An upper level trough just to our west will produce a small upper
level cutoff low which is expected to slide into Central CA late
tonight and into early tomorrow morning. Expect onshore flow to
usher in the marine layer again tonight, leading to cloudy skies and
cooler temperatures. IF the marine layer is able to make it about
1500 ft again or so, expect a similar clearing pattern for tomorrow
and similar high temperatures as to what we see today.

&&

.LONG TERM...
(Monday night through next Saturday)
Issued at 153 PM PDT Sun Jun 8 2025

Upper level ridging holds through Tuesday, with the ridging being
pushed into the Desert Southwest early Wednesday. This is due to a
quick moving upper level shortwave diving across the PacNW and
Northern CA with it quickly moving east throughout the day. This
will leave us with quasi-zonal to weak upper level troughing for a
brief period on Thursday, before upper level troughing takes hold of
the forecast for Friday and the weekend. High temperatures remain a
touch warmer on Tuesday before falling and then generally holding
near the seasonal averages for the rest of the forecast period.

.AVIATION...
(18Z TAFS)
Issued at 1034 AM PDT Sun Jun 8 2025

Mix of MVFR cigs along the coast and VFR inland through today.
High confidence in clearing times at most terminals with the
exception of coastal terminals such as MRY and HAF. While other
terminals will remain stable SKC, HAF is likely to bounce in and
out of SCT-BKN through midday before BKN/OVC prevailing again
later this afternoon. Otherwise high confidence in stratus return
tonight with another round of MVFR/IFR cigs.

Vicinity of SFO...Pretty reliable clearing signal over the
peninsula currently, so high confidence in VFR through today. Also
high confidence in stratus return this evening with MVFR cigs. Not
much variation in marine layer depth over the current TAF period.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Relatively short VFR window midday today
along coastal areas. Good onshore flow and deeper marine layer
restore MVFR/IFR cigs with high confidence later this afternoon.

&&

.MARINE...
(Today through Friday)
Issued at 438 AM PDT Sun Jun 8 2025

A fresh to strong westerly breeze will develop across the bays
this afternoon and persist through the evening. A more widespread
fresh NW breeze will arrive Monday afternoon across the coastal
waters. A low amplitude, long period southwesterly swell arrives
Monday, bringing enhanced currents and causing waves to break in
deeper water. Strong NW winds and rough seas are expected to
arrive by mid-week.

&&

.BEACHES...
Issued at 117 PM PDT Sun Jun 8 2025

A long period southerly swell will enter the waters Monday into
Tuesday bringing a higher risk for rip current along beaches.
Breaking waves about 5 to 7 feet, but strong currents and sneaker
waves will be the bigger hazard. Use caution near the water and
never turn your back on the ocean.
