.SHORT TERM...
Issued at 1231 PM PST Wed Nov 19 2025
(This evening through Thursday)
The last round of rain for this week arrives this evening and will
gradually spread from north to south overnight. Rain may be
lingering during the morning commute hours depending on your
location, with areas south of San Francisco and the East Bay having
the best chance. Road will be slick and there is a possibility for n
nuisance flooding, such as minor ponding of water on roadways, poor
drainage, or urban areas. Once the front works through, there may be
some post frontal showers though those will diminish as drier air
works its way into the region. In addition to rain, some gusty winds
of 30-40 mph are expected along the coasts and higher terrain. Rain
amounts for this system haven't changed much with the terrain of the
North Bay, Santa Lucia, and Santa Cruz mountains potentially seeing
up to 0.25-0.50" while everywhere else is closer to 0.10-0.20" or
less.

expected for interior valleys, the mid 50s to mid 50s along the
coast, and from the 50s to upper 60s for those in higher terrain.
