.SHORT TERM...
Issued at 151 AM PDT Thu Oct 9 2025
(Today and tonight)
A surface trough extending from NorCal south to offshore of the
Central Coast will linger along the coastline today as the first of
several upper level shortwave troughs ejects east from the base of
the upper closed low to our north. Light rain and/or drizzle is
expected to persist across the North Bay most of today into tonight,
while coastal locations from the Bay Area south down to the Big Sur
will see periods of drizzle through most of the morning into the
early afternoon. As the upper low off the Pacific Northwest coast
deepens and slowly pushes onshore tonight into tomorrow a cold front
will drop temperatures in the North Bay into the mid-40s by early
Friday morning, with 50s most other locations, except for higher
elevation areas of the Central Coast that will also drop into the
40s.

(Friday through Wednesday)
Light rain chances linger across the North Bay Friday and begin to
taper off by early Saturday morning behind a second cold front that
won`t impact day time highs much, with temperatures rebounding under
sunny skies and a drier airmass Saturday afternoon. Upper level
shortwave ridging Saturday will result in a pleasant day area wide
under mostly sunny skies. Sunday will be similar to Saturday while
the upper level pattern shifts to zonal flow across the region. By
Monday the next rainmaker starts deepening to our north. Consensus
is improving with increasing confidence of multiple rounds of
wetting rain area wide from late Monday through Wednesday.
