.UPDATE...
Issued at 915 PM PST Tue Jan 13 2026

Felt more like spring than winter today across the Bay Area with
well above normal temperatures. Lots of temperatures hit the 60s,
but the real warmth was across the South Bay and Central Coast
with temps in the 70s and a few in the low 80s. Offshore flow,
dry airmass, and mild 850mb temperatures were the cause.

Speaking of offshore flow, the latest offshore gradient is -13mb
from SFO-WMC. Thankfully it's winter and fuel moisture is high
enough to not be a fire weather concern. Regardless, we'll still
see some decent winds across the higher terrain. Latest
observation shows winds of 20-30 with gusts to 35 mph over the
higher peaks of the North and East Bay. Did a quick update to the
forecast to highlight the uptick in wind. Read below, but the
offshore winds will likely hamper ideal radiational cooling
conditions.

No other updates needed.

.SHORT TERM...
Issued at 200 PM PST Tue Jan 13 2026
(This evening through Wednesday)

Tranquil conditions are anticipated to continue through the short
term forecast period. Water vapor imagery at this hour shows our
H5 ridge remains parked across our region. In addition to a few
upper level high clouds, large scale subsidence should result in
fair weather over the next 5 to 7 days. The MinT forecast remains
a little tricky as the column remains dry and skies are mostly
clear. This would typically promote very ideal radiational
cooling. In fact, our 12Z RAOB PWAT of 0.25" is actually closer
to the 10th percentile for this time of year. This dry airmass has
allowed temperatures to climb quickly into the 60s, with the
warmer spots across the Central Coast. As noted in the update this
morning, we'll see a rather sharp diurnal temperature curve and I
anticipate that we'll still have some chill in the air by
daybreak Wednesday. The discernible difference between Wednesday
morning and the previous AM's will be an uptick in the 925mb flow.
Forecast speeds are anticipated to range between 5 and almost 15
knots in some spots. While seemingly meager, this may perturb the
PBL sufficiently such that it doesn't fully decouple and optimize
radiational cooling. The probability of locales dipping down to or
below 32F appears to be less than 10% across the area, though
some of the sheltered/valley locations may still have an
opportunity to see temperatures fall down to near "freezing" as
these locales may more readily decouple from the free atmosphere.
All that to say, widespread cold similar to the previous nights is
NOT expected on Wednesday morning. That said, continue to protect
any sensitive plants/vegetation if compelled and always use
appropriate indoor heating appliances.

The other impact of the wind may be to limit the widespread fog
development. Similar to the cold, areas that are more sheltered
from the wind (lower elevations) and areas near bodies of water
may have a higher fog potential. Currently, the best
probabilities for fog, occasionally dense, will be across the
North Bay river valleys, and across portions of the East Bay
(where Tule Fog may attempt to encroach across the area).

Wednesday should be another pleasant day with highs in the 60s to
mid 70s. In fact, there are some hints of 80 degree weather
(around a 15-20% chance) across the Santa Lucias, the Diablo
Range, and Santa Cruz Mountains on Wednesday. Quite pleasant for
the typical "rainy" season and certainly above normal (by 10 to 15
degrees) for this time of year. "Minor" HeatRisk is advertised
and this equates to some heat impacts for very sensitive groups.
However, the primary hazard may be the elevated risk for rip
currents and sneaker waves, so be mindful of this threat if you're
heading to the water.

.LONG TERM...
Issued at 200 PM PST Tue Jan 13 2026
(Wednesday night through next Monday)

The pleasant conditions are forecast to continue into this weekend
as mid/upper level ridging remains in place across our area.
Morning fog/stratus should dissipate quickly with daytime heating
and turbulent mixing. We'll keep tabs on the westward extent of
any Tule fog that develops across the Central Valley, but at this
time, impacts are expected to be confined to interior reaches of
the North Bay and East Bay. The warmest day in the outlook period
appears to be Thursday at this time. However, depending on how
the airmass modifies and the exact position of the mid-level
ridge, the warming trend could continue this weekend.

High pressure will really dominate the weather through the long
term period, with guidance indicating it'll remain anchored across
our region. There's high confidence in the synoptic pattern as the
multi-model ensemble exhibits very little in the way of spread
through at least this weekend. As we have been advertising
through the week, the nice weather will make for very ideal beach
conditions. With a continued risk for longer period westerly
swell, the threat for sneaker waves and rip currents will persist.
Be sure to check conditions before you head to the beach.

While the multi-model ensemble largely mimics a majority of the
clustered NWP solutions, there is some variability in the extent
of the upper ridge as we get toward the end of the weekend. Toward
the middle of next week, some guidance advertises a potent upper
trough will dive through Big Sky Country and this may start to
dislodge our ridge westward. This would potentially crack the
storm door open as upper troughing amplifies. Nothing appears
overly impactful at this time, but we are trending toward
temperatures returning to near or even falling below normal with
perhaps the region's next opportunity for measurable rainfall by
the middle to end of next week.

.AVIATION...
(06Z TAFS)
Issued at 920 PM PST Tue Jan 13 2026

VFR at most locations with the exception of North Bay valley FG
and Tule FG gradually making its way through the delta overnight
tonight. As of this issuance, KSTS already seeing reduced VIS and
will likely remain so overnight. KCCR and interior East Bay
terminals also likely see remain in reduced VIS into Wednesday
morning. Other terminals that may see reduced VIS are KAPC and
other immediate Bay Area terminals. Lower confidence here,
however. Included in TAFs to convey confidence in occurrence, but
confidence in coverage is low due to subtle terrain effects.
Otherwise calm or light offshore winds through much of the period.

Vicinity of SFO...Mostly VFR through this period with the
exception of the mornings around sunrise, but it's a low
confidence situation with lingering FG around the Bay Area.
Guidance is rather confident in FG or low stratus over the Bay,
but unclear regarding terminal impacts. Otherwise light offshore
winds.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...VFR. Light and variable winds with a
slight offshore component. Drainage flow out of the SE overnight
may lend to higher winds than depicted in TAF up to 8-10 kts.

&&

.MARINE...
(Today through Sunday)
Issued at 858 AM PST Tue Jan 13 2026

Gentle to moderate easterly to northeasterly winds continue today,
before northerly winds return on Wednesday. Offshore winds return
Thursday and Saturday before northerlies return over the weekend.
Moderate seas will prevail through the week with the exception of
the northwestern portion of the waters where rough seas will
briefly build in Wednesday into Thursday.
