.SHORT TERM...
Issued at 113 PM PST Sat Nov 29 2025
(This evening through Sunday)

Tule fog continues through this weekend with solid moisture
working its way into the North Bay valleys as well. Once again had
to tamp down the temp forecast for these areas today. Persistent
fog and stratus can be expected again tomorrow with at least a
better chance for earlier clearing. Elsewhere, temperatures around
seasonal normals continue with quiet conditions and mostly clear
skies.

.LONG TERM...
Issued at 113 PM PST Sat Nov 29 2025
(Sunday night through next Friday)

Things finally start to change a bit Monday as we dry out during
the afternoons. The passage of a weak mid-level trough promotes
mixing of dry continental air, so we can finally say goodbye to
the all-day cloudiness that we`ve been seeing in the North Bay.
That`ll give everyone a few very nice days going into next week.
Next up is an inside slider that is now being advertised
with reasonable confidence by ensemble guidance. Wednesday morning
we`re anticipating offshore winds across the interior North Bay.
This will result in additional drying across the interior for
these northern zones with daytime RH in the 30-40% range, as well
as some compression of the marine layer. In terms of rain, we`re
still kicking the can down the road so to speak. Not looking good
for rain chances for anyone before the middle of the month.

course and continue to bring IFR to LIFR conditions through
tomorrow AM with some afternoon clearing.

.MARINE...
(Tonight through next Friday)
Issued at 827 PM PST Sat Nov 29 2025

High pressure off the Oregon coast will maintain gentle to
moderate northerly breezes through early Sunday. Northerly flow
will increase through out the day on Sunday. Winds will be locally
stronger over the outer waters and coastal jets. Wave heights and
swell energy increase early next week.

.BEACHES...
Issued at 828 PM PST Sat Nov 29 2025

Hazardous beach conditions will continue into next week with a
very energetic surf zone.

A beach hazards statement remains in effect for the coastline
from Sonoma County to Monterey County through 10 PM PST Sunday
evening. Sneaker waves can unexpectedly run significantly farther
up the beach than normal, including over rocks and jetties. Rip
currents are typically more frequent and stronger in the vicinity
of jetties, inlets, and piers.

A set of forerunner waves arrive early next week renewing the
danger for sneaker waves.
