.SHORT TERM...
Issued at 1048 PM PDT Thu May 28 2026
(Today and tonight)
Small pockets of light rain may linger for the remainder of the
overnight to around sunrise with only traces to a few hundredths
expected where it does rain. Otherwise we'll begin to dry out in the
wake of the upper low now exiting east of our area. However,
temperatures today will continue to be 5-10 degrees below normal
for most locations under a a mix of sun and clouds this afternoon
with some breezy northwest winds up to 25mph through the Salinas
Valley and interior higher elevations of the East Bay Hills and
Santa Clara Hills.

.LONG TERM...
Issued at 1048 PM PDT Thu May 28 2026
(Saturday through Thursday)
Zonal flow into the weekend will transition to weak progressive
ridging for Sunday into the beginning of next week when temperatures
return closer to normal. Guidance has been struggling with a
developing upper level low moving out of the Gulf of Alaska late
next week. Consensus seems to be improving toward another trough at
our latitude for the end of next week into next weekend with what
appears to be little to no impactful weather hazards.
Temperatures appear to remain right around to slightly above
normal through most next week before the trough brings another
round of cooler temperatures, with what appears to be mostly dry
conditions attm.

.AVIATION...
(12Z TAFS)
Issued at 425 AM PDT Fri May 29 2026
A band of showers is making its way through the Bay Area and should
continue moving southwards through the next few hours, with the
showers dissipating around sunrise. These showers are generally high-
based and ceilings generally remain at a low-end VFR throughout the
region with the possibility of MVFR-IFR ceilings developing in the
coastal and higher elevation regions. Clearing skies are expected
through the afternoon with some lingering stratus possible at the
coast and higher elevations. Light winds prevail through the morning
with breezy onshore winds developing in the afternoon. Stratus
returns to the inland regions late this evening as the winds
diminish.
Vicinity of SFO... VFR at present with moderate confidence of MVFR
ceilings briefly developing this morning in the wake of shower
activity. VFR should return this afternoon as breezy west winds
develop, with another period of MVFR ceilings possible tonight into
Saturday morning as the winds diminish.
SFO Bridge Approach... Similar to SFO.
Monterey Bay Terminals... MVFR-IFR ceilings developing at present
and continuing through the morning hours, with ceilings lifting, but
not expected to completely scatter out, in the afternoon. Breezy
northwest winds develop in the afternoon and evening hours,
diminishing in the late evening as IFR ceilings return.

.MARINE...
(Today through Wednesday)
Issued at 425 AM PDT Fri May 29 2026
Some isolated to scattered showers are possible in the inner
waters through the morning hours as a shortwave trough passes
through. Marine conditions will briefly improve today before
strong high pressure rebuilds and generates a strong northerly
breeze and rough seas this weekend, with occasional gale force
gusts possible in the far outer waters and the coastal jets.
