.KEY MESSAGES...
Updated at 1238 PM PST Fri Nov 28 2025

 - Mild and quiet, beautiful weather through the weekend.

 - Pattern continues into much of next week. Breezy offshore winds
   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...
(18Z TAFS)
Issued at 959 AM PST Fri Nov 28 2025

Another challenging and impactful morning for Bay Area terminals
due to another push of low clouds and patchy fog. Lack of mixing
has led to slow clearing - if you want to call it that. OAK will
be VFR through this afternoon, but SFO and SJC will struggle.
Pushed back clearing, but could see it even delayed 19-20Z. N and
E Bay SCT late again 20-21Z. Monterey Bay VFR. Will bring clouds
and patchy fog again tonight.

Vicinity of SFO...Cams show pockets of blue NE of terminal. Will
keep IFR conditions through 19Z, but could see gradual clearing
19-20Z. Expecting VFR this afternoon. IFR cigs again tonight
impacting Sat AM rush.

SFO Bridge Approach...Low cigs impacting approach too, just like
SFO. VFR later this afternoon.

Monterey Bay Terminals...VFR. A few clouds may develop tonight,
but not until late. Hi-res guidance keeps drier air around 
Monterey Bay and went drier.

.MARINE...
(Today through Wednesday)
Issued at 959 AM PST Fri Nov 28 2025

Northerly flow will persist over the coastal waters. Winds will be
locally stronger to fresh breezes south of Point Pinos until
Saturday. Winds will decrease early Saturday before increasing
late Saturday into early next week. Hazardous marine conditions
return midweek as a cut-off low moves through the coastal waters
with winds increasing and wave heights building due to incoming
long period westerly swell.

&&

.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.

PZ...Small Craft Advisory until 9 PM PST this evening for Pt Pinos to 
     Pt Piedras Blancas 0-10 nm.
