.SHORT TERM...
Issued at 159 AM PST Mon Feb 2 2026
(Today and tonight)

An upper level ridge will build overhead today, bringing
continued dry conditions and above normal temperatures. Clear
skies aloft and light winds this morning and again late tonight
will allow patchy fog to develop primarily in the North and East
Bay valleys, with a lower (but non-zero) potential for fog along
the coast and SF Bay shoreline. Motorists that encounter fog
(locally dense) should slow down, use low-beam headlights, and
leave plenty of distance ahead of them. Low temperatures will be
near normal, mainly in the 40s, but some interior valleys will dip
into the upper 30s. Highs today will be similar or slightly
warmer than yesterday as light onshore winds keep warming in
check, with temperatures up to 5 degrees above normal along the
coast and 5-10 degrees above normal inland.

While impacts from minor coastal flooding will be lower than
previous days, high astronomical tide late this morning into early
this afternoon will still bring minor flooding to bayshore
locations along the San Pablo Bay in the North Bay. Hazardous
beach conditions continue at Pacific Coast beaches through this
evening, read more in the BEACHES section.

.LONG TERM...
Issued at 159 AM PST Mon Feb 2 2026
(Tuesday through Sunday)

Tuesday through Thursday, winds will turn more offshore as the
ridge strengthens and slowly shifts to the northeast. This will
boost highs by 4-8 degrees from today, with Wednesday expected to
be the warmest day. This will translate to highs in the 70s to
around 80 in interior valleys, and mid 60s to lower 70s near the
coast.

On Friday, the ridge will shift east as a weak trough (or even a
closed low in some models) moves near the coast. For now, rain
chances from this feature are very low (less than 10%), but a more
favorable track of this system could increase chances of light
rain. Temperatures are expected to cool a few more degrees with
winds shifting more onshore during the afternoon.

The pattern is finally expected to change more significantly
Saturday into early next week as upper level troughing becomes
more prominent along the West Coast. The trough will bring
precipitation to the Pacific Northwest by Saturday, with rain
chances extending south into northern and then central California
by Sunday and Monday as the trough deepens and progresses to the
east, accompanied by a cold front. However, rain amounts at this
time appear to be light and not very impactful, with a continued
cooling trend. That said, confidence is fairly high on the overall
change to upper level troughing along the coast (85-90% chance of
occurrence), with larger uncertainty on timing and strength of
the trough.

.AVIATION...
(12Z TAFS)
Issued at 257 AM PST Mon Feb 2 2026

Currently VFR at all terminals. Patches of fog/stratus have been
observed intermittently overnight - expect this to continue through
mid-morning. High confidence in VFR prevailing through the TAF
period by this afternoon with moderate confidence on sub-VFR
conditions returning to STS tonight. Diurnal winds will prevail.

Vicinity of SFO...Currently VFR with light southerly flow. High
confidence in VFR through the TAF period. Diurnal winds will
prevail today, offshore flow returns tomorrow.

SFO Bridge Approach...Similar as SFO.

Monterey Bay Terminals...Currently VFR with drainage winds at
both terminals. High confidence in VFR through the TAF period.
Diurnal winds will prevail.

.MARINE...
(Today through Saturday)
Issued at 257 AM PST Mon Feb 2 2026

Hazardous conditions are expected today for the inner waters and
outer waters due to rough seas and fresh to strong northerly
breezes. Conditions improve tomorrow as moderate seas and a gentle
northeasterly breeze prevails through Thursday. By Friday, seas
build to become rough and northwesterly breezes increase to become
moderate.

&&

.BEACHES...
Issued at 257 AM PST Mon Feb 2 2026

Hazardous beach conditions will continue through this evening at
Pacific Coast beaches. Long period westerly swell will bring an
increased risk for sneaker waves and strong rip currents with
breaking waves of 14 to 19 feet. Remember: stay off of jetties,
piers, rocks, and other waterside infrastructure, remain out of
the water, and never turn your back on the ocean!
