 - Mild and quiet, beautiful weather through the weekend.

   in the North Bay interior Wed/Thu. Minimal impact.

 - Need to look just beyond the 7 day forecast for next chance of
   rain. High uncertainty if we`ll actually get any then.

.SHORT TERM...
Issued at 1238 PM PST Fri Nov 28 2025
(This evening through Saturday)

Stagnant pattern remains. Beautiful weekend full steam ahead,
unless you`re caught up in the Tule fog and stratus in the
interior East Bay and North Bay. These locations will hold on to
fog and clouds through much of the day today, and will likely
copy/paste tomorrow as well. Believe it or not, Santa Rosa is
actually one degree warmer than this time 24 hours ago! Elsewhere
we`re seeing temps around seasonal normals with highs in the upper
50s and lower 60s.

.LONG TERM...
Issued at 1238 PM PST Fri Nov 28 2025
(Saturday night through next Thursday)

Pretty benign conditions through much of next week. One notable
period for now looks like Wednesday and Thursday mornings where we
are likely to see some breezy offshore winds in the North Bay
interior thanks to the deep retrograding low to our south that
we`ve been mentioning. At the moment this doesn`t appear like
it`ll cause any issues. As we get into the latter half of the
week, there is some uncertainty regarding how this low will act as
it weakens and starts to finally get caught up in the steering
flow, pulling it eastward. Looking just beyond the 7 day period
may bring us our next light rain maker as the system moves back
ashore. This still being very uncertain, but it`s at least the
next reasonable time for actual rain.

.AVIATION...
(06Z TAFS)
Issued at 935 PM PST Fri Nov 28 2025

Low clouds and pockets of fog are reestablishing as winds reduce
into the night. Expect nearly widespread CIGs by the late night.
Slightly drier flow affects the region tomorrow with increasing
winds. This will offer earlier clearing times, and lead to
widespread VFR by the mid afternoon. Low CIGs return again into
Saturday night as winds reduce across the region.

Vicinity of SFO...Expect mostly light winds through the TAF
period. IFR CIGs are building around the SF Bay and look to become
more consistent later into the night. These CIGs scatter into the
late morning and cloud cover clears as winds turn northwest into
Saturday afternoon.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Low clouds and pockets of fog have formed
around the Monterey Bay and are affecting the terminals while
winds have become light. Cloud cover erodes into the late morning
as northwest winds build, but these winds look to become light and
variable into Saturday night.

&&

.MARINE...
(Tonight through next Thursday)
Issued at 935 PM PST Fri Nov 28 2025

Winds continue to decrease into the night, but will increase  into
early Sunday. Hazardous marine conditions return in the late
weekend as swell heights increase. Winds increase and wave
heights build due to incoming long period westerly swell in the
mid work week.

&&

.BEACHES...
Issued at 338 AM PST Fri Nov 28 2025

Moderate to long period northwesterly swell will result in an
increased risk for sneaker waves and rip currents. Breaking waves
of 13 to 18 feet are expected. A beach hazards statement is 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.

&&

.MTR WATCHES/WARNINGS/ADVISORIES...
CA...Beach Hazards Statement through Sunday evening for CAZ006-505-
     509-529-530.
