.SHORT TERM...
Issued at 117 PM PST Tue Mar 3 2026
(This evening through Wednesday)
Mostly sunny skies have returned to the region this afternoon,
except for coastal locations of Marin County and the San Francisco
Peninsula. As such, temperatures are forecast to warm up to
around 10 degrees F above seasonal averages in the warmest
interior valleys has a short wave ridge builds ahead of an
approaching mid/upper level trough.
A rather dry cold front is forecast to move through the region on
Wednesday morning with increasing north to northwest winds
developing by the late morning and more so by the afternoon. There
remains a slight chance for light rain across far northern Sonoma
County, yet not expecting much if any measurable rainfall. The
strongest winds tomorrow will remain over the coastal waters,
along the coastline, and in the higher terrain with gusts up to
35-45 mph. However, at this time, we do not anticipate a Wind
Advisory as widespread coverage does not appear to be great
enough. Temperatures Wednesday afternoon will be near seasonal
averages in wake of the frontal passage with clearing skies.

.LONG TERM...
Issued at 117 PM PST Tue Mar 3 2026
(Wednesday night through next Monday)
Moderate winds are forecast to resume Wednesday night into
Thursday and will limit the cooling potential. As such, expecting
upper 30s to lower 40s across the interior with low to upper 40s
across the remainder of the region. Winds increase once again
Thursday afternoon with similar directions and speeds as
previously mentioned in the short term discussion.
Friday and Saturday will begin a warming trend as the mid/upper
level low pressure moves from the Great Basin into the
Intermountain West. This will result in offshore flow, especially
for the higher terrain across the region. By Sunday afternoon,
temperatures are forecast to be between 10 to 20 degrees above
normal resulting in more widespread Minor HeatRisk. This will be
as a mid/upper level cut off low develops off the coast of Baja
California.
The forecast ensembles show continued ridging across the region
which supports the Climate Prediction Center's above normal
temperatures and below normal precipitation in the 8-14 Day
Outlooks.

.AVIATION...
(18Z TAFS)
Issued at 934 AM PST Tue Mar 3 2026
Lingering MVFR-LIFR stratus and fog continue across the Bay Area
and the southern Monterey Bay region, with further dissipation
expected through the next few hours barring the immediate coast
near Point Reyes and the western side of the San Mateo Peninsula,
where the stratus could linger through the day. A light to gentle
onshore flow will develop this afternoon, lingering into the
evening as the stratus returns to the valleys. The passing of a
cold front may result in some sprinkles overnight into Wednesday
morning, but the main impact will be to maintain a moderate
northwest breeze through the night before winds increase Wednesday
afternoon, after the end of the 24-hour TAF period.
Vicinity of SFO... MVFR-IFR stratus lingers for the next couple of
hours. A gentle to moderate west-northwest breeze will develop
through the afternoon and evening hours, with winds remaining gentle
overnight as MVFR stratus returns to the terminal. Stronger winds
are expected to develop on Wednesday as a cold front passes.
SFO Bridge Approach... Similar to SFO.
Monterey Bay Terminals... Lingering stratus should dissipate within
the next hour. A gentle northwest breeze should develop in the
afternoon, with light winds this evening as MVFR stratus returns
overnight. Winds begin to increase from the north towards the end of
the TAF period, with clearing of the stratus around or just after
the end of the TAF period.
&&
.MARINE...
(Today through Sunday)
Issued at 846 AM PST Tue Mar 3 2026
Expect hazardous marine weather conditions Wednesday through
Friday. A moderate northwest breeze today increases to a strong
northwest breeze on Wednesday and near gale force winds by
Thursday. These winds will build very rough seas of 12 to 15 feet
across exposed waters Thursday through Friday.
