AREA FORECAST DISCUSSION
National Weather Service Eureka CA
150 AM PST Wed Dec 3 2025
.SYNOPSIS...High pressure continues to build over the area,
bringing offshore flow and generally clear skies through Thursday
along with night and morning valley fog. Light rain is possible
mainly in Humboldt and Del Norte counties over the weekend.
&&
KEY MESSAGES:
* King Tides from December 3rd-7th may lead to minor coastal
flooding in low-lying areas mainly around Humboldt Bay.
* Frost is possible Wednesday and Thursday morning in the colder
valleys and along the coast.
* Dry and seasonably cool weather expected through Friday,
followed by a chance of rain over the weekend.
&&
.DISCUSSION...High pressure over the area is bringing fairly
robust offshore flow to the area. East winds will be breezy on
the ridges both Wednesday and Thursday mornings. These are
expected to be the strongest Wednesday morning. Gusts to 30 to 35
mph are possible on some of the higher peaks, especially in
eastern Lake county. These may mix down to some of the northeast
to southwest oriented valleys. This is expected to limit fog
development and may allow frost to form in the some of the valleys
that haven't frozen yet. So have issued a frost advisory for a
number of these areas. It is still possible low clouds will be
more widespread than expected, but for now it looks like frost is
likely. Wednesday, another dry day is expected. Any valleys that
do fog up will likely be slow to clear out and warm up during the
day. Wednesday night into Thursday morning is expected to see
lighter winds aloft, but the air is expected to be drier. This
would make it likely to be slightly colder Thursday morning.
Thursday night into Friday morning a shortwave coming over the
ridge is expected to start bringing more cloudiness to the area.
This will likely keep temperatures warmer. It is possible this
could bring some drizzle to the northern coastal areas, but
confidence is low on this. Friday afternoon looks like the first
chance for some light rain and this may continue through the
weekend. The big question is how far south this rain will come.
The current forecast keeps most of it in Del Norte county with
less than a quarter of an inch in northern Humboldt county. Del
Norte count may see over a half inch. However this is a small
system and a slight shift farther north or south could really
change the rainfall totals. This is highlight in the 75th and 25th
percentiles from the NBM. The 25th percentile for Crescent City
shows 0.2 inches while the 75th percentile shows 1.1 inches. In
Eureka and much of Humboldt and Trinity counties those amounts
range from 0.00 to 0.5 inches. Farther south and east in southern
Trinity, Mendocino and Lake counties even the high ends amounts
are less than a quarter inch. Even if the heavier amounts make it
farther south, there aren't expected to be many impacts. MKK/EYS
&&
.AVIATION...Offshore flow continues to prevent coastal
stratus from forming, with VFR likely to prevail through the night.
Shallow ground fog could bring brief LIFR impacts before sunrise,
but impacts are expected to be limited. Interior valleys, including
UKI, could see stratus and fog again near sunrise, but confidence is
low. Any fog that does form should clear out by mid to late morning.
Winds could be breezy again in the afternoon at CEC, with gusts up
to 20 kts. JB
&&
.MARINE...North winds peak tonight with gale force gusts likely for
the outer waters. These will ease slightly into Wednesday morning
and push away from the coast. Still, gusts of up to 30 kts are
likely through Thursday morning. Steep wind waves are being observed
alongside these winds, which is combining with a decaying mid-period
westerly swell of around 7 ft. Combined seas of 10-14 ft are likely
tonight with will gradually ease to 6-10 ft by Wednesday evening.
Winds and seas ease further Friday, with the main exception being
the expansion fan south of Cape Mendocino. Conditions continue to
improve going into the weekend as high pressure weakens. JB
&&
.COASTAL FLOODING...High astronomical tides are predicted from
through Sunday for Northwest California. Water levels remain nearly
a half a foot above astronomical tides inside Humboldt Bay and this
may cause minor flooding starting Wednesday, so a Coastal Flood
Advisory has been issued for Humboldt Bay. The tides continue to get
higher over the next several days and additional flooding is
expected around Humbodlt Bay. Outside of Humboldt Bay the tide
gauges are showing a slight negative anomaly as the swell continues
to diminish. At this point we aren't expecting coastal flooding
outside of Humboldt Bay, but this will need to be watched as it gets
closer. MKK

155 AM PST Wed Dec 3 2025
.KEY MESSAGES...
1. Fog development will continue overnight into Wednesday
morning across the San Joaquin Valley.
2. A dry disturbance will introduce increasing winds across the
deserts and mountain peaks on Wednesday and Thursday; cold
morning lows also anticipated for the high Sierra.
&&
.DISCUSSION...
Low stratus cloud cover continues over the central valley this
afternoon after lifting from the valley surface. Stagnant and
subsiding air aloft will cause rising moisture from the valley
to settle in the low levels of the atmosphere, gradually
improving visibilities at the surface. However, a knock-on
effect will need to occur to remove this stratus cloud deck
where warmer surface temperatures cause the clouds to erode,
which will in turn lead to more of the surface receiving
sunlight, causing warmer temperatures, and so on.Clearer skies
yesterday came about with help from stronger low level winds
mixing out the saturated air, which will likely need to happen
again today, given that the persistence of the stratus deck has
extended further than model guidance indicated. Without
clearing, we can expect this cloud deck to continue into
tomorrow morning.
This being said, a shortwave upper level trough is expected to
make its way through the Great Basin this afternoon through
early Thursday morning, with the vorticity maximum of the trough
tracking due north/south over central California. The vortmax
and increased winds at the center of the trough’s axis may allow
for enough low level mixing to occur over the valley areas to
cause clearer conditions to prevail into Wednesday, however
these elements will need to extend into the lower levels in
order to do so. More definitive impacts from the incoming trough
will be seen in the higher elevations of the region. Cold, dry
northerly air will be entrained into this area, causing
dangerously cold conditions Wednesday and Thursday mornings.
Minimum temperatures above 9000 feet are expected to approach 10
degrees Fahrenheit, but with the added effect of the wind,
apparent temperatures are projected to fall into the negatives.
Due to this, a Cold Weather Advisory has been issued for the
Sierra Nevada above 9000 feet.
Starting in the late week, more benign conditions will return
due to the influence of a high pressure ridge over the eastern
Pacific. The high will direct more significant weather further
north and east of central California, while prolonging the
stagnant conditions currently observed over the region.
&&
.AVIATION...
IFR/LIFR visibilities are expected at all TAF sites for the next
24 hours. Between 12Z and 19Z Wednesday, VLIFR conditions have
a 40% to 60% chance of occurring in dense fog. Conditions are
expected to see brief improvements into MVFR conditions between
22Z Wednesday and 03Z Thursday.

Area Forecast Discussion
National Weather Service Los Angeles/Oxnard CA
217 AM PST Wed Dec 3 2025
.SYNOPSIS...03/119 AM.
A moderate Santa Ana wind event will bring gusty northeast winds
to portions of southern California Wednesday morning through
Thursday. Cold overnight low temperatures will occur through the
work week, coldest Wednesday night into Thursday morning in wind
protected areas. A significant warming trend will begin this
weekend and peak next Tuesday and Wednesday at 10 to 20 degrees
above normal.
&&
.SHORT TERM (TDY-FRI)...03/154 AM.
A cold upper level trough is passing through the southern portion
if the Great Basin this morning, creating thick cirrostratus over
the region but no precipitation locally. The marine layer has
jumped up over 2500 feet and pressure gradients to the east have
gone from 2-3mb offshore to over 5mb onshore. Some stratus is
trying to develop but the thick high clouds are making that
difficult to form and also see from space.
The main story for today and Thursday is the rapid shift back to
offshore and the expected development of the next round of Santa
Ana winds across portions of Ventura and LA Counties and the Santa
Lucias. Given the existence of a 2500 foot marine layer there
remains still quite a bit of uncertainty when the northeast winds
will begin and how strong they will be. High res models seem to be
a little too strong for today given the current conditions,
especially near the coast, while confidence in increasing winds is
certainly higher inland and especially in the mountains. The most
likely outcome is for most of the advisory level winds to stay up
in the mountains today while lower elevations have breezy but sub
advisory level winds by mid to late morning. However, there's a
20% chance of much lighter winds closer to the coast today.
Going into tonight and Thursday with zero marine layer influence
and more favorable easterly flow aloft the chances for 30-50mph
winds are much higher and would likely include gusty winds out to
Catalina Island as well, especially tonight.
This is again a fairly cool Santa Ana event so high temperatures
will top out in the lower 70s, warmest at the coast and coolest
across the far interior where highs will be in the 50s. And
overnight lows in wind protected locations will be quite cold,
hence the flurry of frost and freeze products out.
By Friday morning gradients will have swung back to onshore which
will result in cooling at the coast but warming inland. Overall
highs will be near or slightly above seasonal norms.
.LONG TERM (SAT-TUE)...03/212 AM.
Strong high pressure will be building rapidly over the eastern
Pacific this weekend and especially the first half of next week.
500mb heights are expected to exceed the 95th percentile and with
increasing offshore flow, particularly Monday through Wednesday,
temperatures locally are expected to be 10-20 degrees above
normal. Local historical guidance suggests widespread highs in
the 80s across coast and valleys with about a 20% chance of lower
90s. There will be some northerly flow developing Sunday night
through Tuesday that will bring dry and gusty winds to north
exposed areas which includes most of the mountains as well as
southern Santa Barbara County.
Temperatures will start cooling next Thursday and Friday but still
well above normal.
&&
.AVIATION...03/0222Z.
At 2350Z at KLAX, there was no marine layer, and no inversion.
Moderate to high confidence in TAFs for KPRB, KSBP, KSMX, and
KSBA, KWJF, and KPMD. At KPRB, KSMX, and KSBA there is a 10
percent chance of IFR-MVFR cigs from 13-16Z Wed.
Low to moderate confidence for KOXR, KCMA, KSMO, KLAX, KLGB,
KBUR, and KVNY. Arrival of any cigs may be off by 2-3 hours from
forecast and may be off by 1 category at times. There is also a
10-20% chance that no cigs form at sites where they are
forecasted. Short-lived IFR- MVFR conditions are possible (20%
chance) between 12Z-16Z Wed at KBUR and KVNY, and there is a 10%
chance of brief dense fog (V/LIFR) conditions across the LA Basin
from 13Z-16Z Wed.
KLAX... Moderate confidence in TAF, cigs may for between
BKN008-BKN025, with a 20 percent chance of VFR conditions through
the period. East winds are possible from 10Z Wed to 20Z Wed, with
a 30-40% chance of the east wind component exceeding 6-8kt.
Best chance for stronger east winds is around 13Z to 17Z.
KBUR...Moderate confidence in TAF, there is a 20% chance of
BKN008-BKN025 cigs between 12Z-17Z Wed.
&&
.MARINE...02/942 PM.
For the outer waters, moderate to low confidence in the current
forecast. The NW swell came in somewhat lower than expected,
therefore Small Craft Advisories were canceled for the outer
waters south of Point Sal. Some localized winds may gust near SCA
levels at times tonight, but should be short-lived. Then winds
and seas should mostly remain below Small Craft Advisory (SCA)
levels Thursday through Saturday, with winds increasing to near
SCA levels at times, mainly Friday night and Saturday night.
For the nearshore waters, easterly winds are expected to develop
from the Ventura County Coast into the Santa Barbara Channel late
morning to early Wednesday afternoon. Localized gusts near SCA
levels will be possible through the afternoon hours. Then there
is a 40 to 50 percent chance of SCA level winds with short- period
seas developing late Wednesday night into Thursday morning.
Northeast Santa Ana wind will be the strongest near the coastline
between Ventura Harbor and Santa Monica. Late Thursday through
Saturday, winds and seas are expected to generally remain below
SCA levels.

National Weather Service Sacramento CA
1249 PM PST Tue Dec 2 2025
.KEY MESSAGES...
- Periods of clouds, mist, or fog continue in the Central Valley
for the next few mornings.
- Breezy north to east winds Wednesday into Thursday, strongest
in the western Valley and Delta.
- Weak system brushes by the area this weekend, bringing the
chance for showers across Shasta County. Dry weather continues
elsewhere for the foreseeable future.
&&
.DISCUSSION...
...Tonight - Wednesday...
Morning fog and stratus have begin to break up early this
afternoon again. Latest hi-res guidance attempts to clear out the
entire Sac and northern San Joaquin valleys by this evening
before sunset. We anticipate another round of patchy fog/low
stratus Wednesday morning with best chances Sacramento southward
and still breaking up during late morning, early afternoon hours.
Chances lower north of Sacramento due to increasing north winds in
the Valley set to develop after around midnight tonight that may
keep the worst of the fog from developing. By 4 AM tomorrow, we
can expect north gusts 20 to 30 mph along the west side of the
Valley along I-5 and have those winds persist into the early
afternoon before tapering off Wednesday night. The Delta region
can expect slightly higher winds closer to 25 to 35 mph with
strongest winds early Wednesday morning. NBM probabilities for
Wednesday show a 40-70% chance of winds greater than 35 mph for
the western portions of Solano, Yolo, and Colusa counties. Lastly
east wind gusts over the Sierra are expected on Wednesday with
gusts up to 30 to 40 mph and strongest Wednesday late morning.
...Thursday - Saturday...
After the quasi-inside slider pattern leaves the area on Thursday,
mild and dry conditions prevail with seasonable temperatures and
foggy/low stratus mornings. Ridging looks to hold along the CA
Coast that keeps the forecast muted from much active weather.
A weak shortwave on Saturday slides from the Pacific NW eastward
that will give a nonzero chance of rain over northern Shasta
County with amounts up to a quarter inch but no impacts are
expected at this time.
...Sunday - Early Next Week...
Dry weather continues late this weekend into early next week. The
next hint at a potential pattern change comes by the following
weekend but we'll see how that develops over the next week or so.
&&
.AVIATION...
Gradually improving ceilings and visibility across the Central
Valley are expected this afternoon and evening, with conditions
back to VFR. Some BF/FG and low stratus for most sites return
tonight after 08Z-14Z with a potential for period of IFR/LIFR
cigs and patchy fog, especially from Sacramento southward.
Northerly winds should limit fog formation to the north in the
Valley. Sustained winds with gusts to 20 to 25 kt are possible
11-18Z Wednesday for the northern Sacramento Valley and to 30kt
for the Sierra, generally less than 10 kts for TAF sites elsewhere
through Wednesday afternoon.

.SYNOPSIS...
The marine layer will deepen overnight into Wednesday morning before
becoming shallower again for Thursday into early next week. Areas of
drizzle or light rain near the coast are possible tonight into
Wednesday, with no impacts expected. Wednesday will be a few degrees
cooler than today, before warmer conditions Thursday into early next
week. The pressure gradient will rapidly switch from onshore to
offshore for the middle to end of the week with periods of gusty
Santa Ana winds.
&&
.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...
This evening, the marine layer is now about 4000 ft deep and areas
of low clouds have formed from the coast to the mtn foothills. By
Wednesday morning, the marine layer is expected to be about 4500
ft deep and the low clouds are likely to fill in all areas west of
the mtns. If the saturated layer becomes thick enough, there
could be some drizzle west of the mtns later tonight. Sfc pressure
gradients continue to trend onshore and westerly winds are
locally gusting 25-45 mph in the wind-prone passes and canyons at
this hour.
From previous discussion...
As the upper level low moves southward into the Great Basin, a
1030 mb surface low will develop. This will bring periods of gusty
Santa Ana winds to foothills and coastal mountain slopes; warming
conditions; and mostly clear skies across the area. Gusty north
winds will develop through and below the Cajon Pass on Wednesday
afternoon with more widespread and stronger northeasterly winds
for Wednesday night into Thursday morning along and below the
coastal slopes of the mountains with peak gusts 40 to 50 mph,
locally up to 55 mph. Northeast to east winds will continue for
Thursday afternoon into Friday morning, but with decreasing
coverage and strength. Gusts on Friday are expected peak at 35 to
40 mph. Lowest daytime humidity on Thursday and Friday for the
valleys and inland coastal areas will fall to 15 to 20 percent.
A few degrees of cooling is expected into Wednesday, with highs a
few degrees below average. A gradual warming will occur Thursday,
with further warming expected through the weekend into early next
week. By Tuesday, highs will be 10 to 15 degrees above average for
inland areas.
&&
.AVIATION...
030400Z....Coasts/Valleys...Patchy low clouds based 2200-3200 ft MSL
with tops to 4000 ft MSL will continue to move to cover the coastal
basin by about 10Z this evening. Patchy -DZ expected, especially
near the coastline 10-16Z, bringing areas of lowered vis 4-6 SM on
occasion. Clouds will intermittently scatter out overnight, with
fuller clearing from east to west 14-18Z. North to northeast winds
gusting 20-30 kts through and downwind of the Cajon pass after 17Z
(including vcnty KONT) and continuing in areas through the
TAF period.
Mountains/Deserts...VFR conditions through the period with FEW-SCT
high clouds AOA 20 kft. West winds gusting 25-40 kts through
mountain passes and along east-facing slopes will weaken 15-18Z,
before turning north to northeast and strengthening again along the
coastal slopes and foothills. Mod up/downdrafts near mtns.

- Gusty offshore winds still slated for late tonight through Wednesday
morning. Generally 25-35 mph with isolated gusts to 55 mph
along higher terrain for the interior North Bay mountains.
- No major fire weather concerns as fuel retain good moisture after
early November rains.

.SHORT TERM...
Issued at 141 AM PST Wed Dec 3 2025
(Today and tonight)
Satellite imagery this morning shows stratus in the valleys
surrounding the Bay Area and the interior Central Coast; however,
the growth of the stratus is slowly getting cut off as the offshore
pressure gradient tightens bringing in drier air to the region.
Offshore winds have already started to ramp up for the North Bay
mountains, with the highest points in Mayacamas and Sonoma mountains
peaking around 50-55mph. Winds will continue for the rest of the Bay
Area and Santa Lucia mountains, peaking by mid morning and the
gradually decreasing as we head into the afternoon and evening.
Given the earlier rains this season, fire weather concerns remain
low due to moist fuels.
&&
.LONG TERM...
Issued at 141 AM PST Wed Dec 3 2025
(Thursday through Tuesday)
The extended forecast remains persistent, with quiet weather
returning for Thursday and lasting into next week. Ensemble
forecasts show mainly upper level ridging, with some quasi-zonal
flow at times, holding into mid to late next week. High temperatures
are seasonal for the start of the forecast period, and increase to
above average for this time of year through mid next week.
&&
.AVIATION...
(06Z TAFS)
Issued at 959 PM PST Tue Dec 2 2025
Mix of VFR and MVFR across the board tonight. The HREF has a pretty
good handle on an initial push of marine stratus along the coastline
that other high resolution models didn't quite capture. Based on
HREF guidance, this stratus push should be fairly short lived and
clear by 10-12Z tomorrow morning as breezy offshore winds develop.
Coastal sites may see gusts to around 20-25 knots with winds peaking
early tomorrow morning and remaining breezy into the afternoon. By
the late afternoon, winds will shift more northerly before easing
overnight. Not currently anticipating fog development tomorrow night
given the influx of drier air tonight.
Vicinity of SFO...Currently VFR. Low confidence that stratus will
reach SFO tonight but the highest likelihood of that occuring would
be between 06-12Z. Offshore winds strengthen after 12Z which should
bring drier air to the region and clear out any lingering cloud
cover around the Bay Shoreline. Winds gust to around 20 knots during
the day before easing overnight.
SFO Bridge Approach...Similar to SFO.
Monterey Bay Terminals...MVFR conditions persist through 10-11Z with
VFR through the rest of the period. Marine stratus has filtered over
both MRY and SNS with HREF guidance suggesting this push will last
through 10/11Z. Around that time winds will switch more offshore and
strengthen slightly. This should bring in drier air and clear out
ceilings over both airports. Winds shift more northerly during the
day before becoming light and, at times, variable overnight.&&

minutes or more between largest sets can be expected. Some of the
favored break points may exceed 20 feet at times. Forerunners
will be 18+ seconds with heights of 2-5 feet into tonight
resulting in the greatest risk for sneaker waves. This combined
with high astronomical tides in the morning hours will increase
the aforementioned risk. 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.
