.SHORT TERM...
Issued at 234 PM PST Sun Nov 1 2026
(This evening through Monday night)
An upper level low and associated cold front worked its way through
the region this morning. Behind it a mix of sun and clouds, with
cool temperatures peaking in the 60s for interior valley locations,
upper 50s to low 60s along the coast, and mid 50s to low 60s in the
hills and mountains. As the sunsets, cumulus clouds should dissipate
and onshore winds will ease. Guidance tonight shows high clouds
moving in, which makes the forecast a bit interesting. Current
thinking is that these will roll in and limit radiational cooling and
radiational fog development. Kept the shot for patchy fog in the
forecast for the interior valleys of the Bay Area, but it will be
dependent on cloud cover and winds. High pressure continues to build
in on Monday which will lead to slightly warmer temperatures and dry
weather.

.LONG TERM...
Issued at 234 PM PST Sun Nov 1 2026
(Tuesday through next Saturday)
A quick moving shortwave trough will bring light rain to Bay Area
and Santa Cruz on Tuesday, with perhaps some showers making into
northern Monterey and San Benito counties. Rainfall amounts look to
be light and generally around 0.15-0.40" for the North Bay, and 0.05-
0.25" for the San Francisco Peninsula, East Bay, and Santa Cruz, and
around 0.0-0.10" for Santa Clara County. south of that amounts in
Monterey and San Benito are generally a couple hundredths of an inch
or less. Once the this shortwave moves through, we'll see a mix of
zonal flow and ridging builds behind it. This will lead to a warming
and drying trend through the week.
