.SHORT TERM...
Issued at 226 PM PST Wed Dec 17 2025
(This evening through Thursday)

A mix of sun and clouds for the remainder of the afternoon in the
wake of a relatively weak cold front that pushed through our area
earlier this morning. Rainfall received overnight and this morning
was beneficial with most low lying areas seeing around a tenth-of-an-
inch, and higher elevations seeing from a tenth-of-an-inch to half-
an-inch. Expect areas of dense fog to develop overnight within
inland valleys. especially the North Bay, Bay Area and East Bay.
Closer to the coast, fog and drizzle will combine to limit
visibility overnight into early Thursday morning.

Thursday will be mostly dry with the exception of the coastal
drizzle that should taper off an hour or two after sunrise.
Thursdays high temperatures will be right around normal, slightly
above normal for higher elevations within the Central Coast. The
first wave of numerous rounds of rainfall will first move into the
North Bay late in the day Thursday with only light rain for the
onset into Friday.

.LONG TERM...
Issued at 226 PM PST Wed Dec 17 2025
(Thursday night through next Tuesday)

Plenty of uncertainty remains with the exact timing and intensity of
the rainfall we`re expecting to impact our area beginning Friday
through the remainder of the extended forecast. What we do know attm
is the North Bay will see the most rainfall as several waves of
moderate/heavy rainfall push through over the next week, along with
elevated coastal ranges from San Mateo south through the Santa Cruz
mountains into the Santa Lucia`s. The period of heaviest rainfall as
of this writing looks to be late Saturday night through early Monday
morning, which means Sunday may be difficult travel day. Give
yourself plenty of extra time to travel at anytime over the next
week, but especially Sunday.

The totals over the coastal ranges will standout on ours and others
weather maps you`ll see as we head into one of the busiest travel
times of the year. However, low lying areas all across our region
will see plenty of impacts from the rain, wind and other cumulative
problems associated with multiple storm systems moving over our
area. By the beginning of next week we are likely to see rivers
begin to swell and the potential for rock and land slides to
interfere with travel plans. Signals for rainfall chances beyond the
scope of our official forecast persist into the end of next week as
well.

Most of the Pacific Coast is highlighted in CPC outlooks for
excessive rainfall through the extended forecast. Please monitor
our web page (weather.gov/mtr) for updated rainfall total maps,
more specific timing and impacts for our area along with our
partners at the CPC for bigger picture products across the West
Coast (cpc.ncep.noaa.gov).
