AREA FORECAST DISCUSSION
National Weather Service Eureka CA
1246 AM PST Sun Nov 30 2025
.SYNOPSIS...A mid period westerly swell will bring a moderate
risk for hazardous beach conditions through Saturday afternoon.
A much more energetic westerly swell will bring a high risk for
sneaker waves Monday through Tuesday. King Tides return on
Tuesday, and peak then on Thursday and Friday. Otherwise, dry and
seasonably cool weather is forecast through next week.
&&
.KEY MESSAGES...
* Dry and seasonably cool weather expected through the next
7-days, with a mix of sunshine and clouds.
* Potential for frost and freezing morning temperatures along the
coastal areas on Monday.
* High risk of sneaker waves is expected along the Northwest
California beaches from Monday morning through Tuesday morning.
* King Tides from December 2nd-7th, and may lead to minor coastal
flooding in low-lying areas around Humboldt Bay, Crescent City
and Arena Cove.
&&
.DISCUSSION...A semi-stationay upper-level ridge over the
northeastern Pacific, while a shortwave continue to drop
southeast inland into the Great Basin. Abundant high-level clouds
continue to stream south-southwest across Northern California
overnight, while surface observations reported some coastal low
clouds and patchy valley fog. Expect another day with dry and
seasonably cool weather, with a mix of sunshine and clouds. Breezy
northerly will continues to develop along the coastal headlands
and exposed ridges today as the surface pressure gradient tighten.
Offshore winds should follow this evening through Monday morning
with perhaps gusts to 25-35 mph over the ridges. The strongest
winds will most likely occur over the eastern portion of Lake
County where gusts from 25 to 35 mph are possible over wind prone
ridges by Monday.
Frost and freezing morning temperatures will also be possible for
coastal areas if the clouds do not reform and dewpoints dry out
near the ocean in response to steady east winds. Granted places
where winds stay up all night, temperatures probably will not even
fall below 45F. Current guidance indicate morning minimums early
Monday above 36F for much of the North Coast. However, NBM
probability indicates there is a 15-25 chance for min temperatures
below 36F around Humboldt Bay and adjacent areas, with up to 80%
chance for McKinleyville. Localized pockets of frost may occur (a
10% chance) along the rest of the NW California Coast.
Another dry shortwave trough will follow a similar track Mon night
and Tue. This trough will dig from NE to SW across the area by
Tue and then offshore the central and southern Cal coast by mid
week. There is an outside chance for a few fleeting light showers
or sprinkles for Del Norte and mountains of Trinity Mon night or
Tue morning, but it will not be a significant precipitation maker
for our forecast area. Once again winds look to be the main impact
with these inside slider troughs. Blustery northerly coastal
winds are expected with this second trough. ECMWF ensemble mean
peak wind gusts are much higher for coastal low lands on Tue.
Gusts around 20-30 mph will be possible. E-NE winds will also
develop Tue night-Wed for the higher terrain and perhaps Lake
County. E-NE wind gusts to 35-45 mph will be possible over the
ridges. Gusts to 50-55 mph are on the limbs of the distribution
(95th percentile) over the high mountain peaks in the King Range.
Now the air mass is not forecast to be exceptionally cold by mid
next week either. With dew points in the 20s, calm winds in the
valleys and clear skies overnight, frost and freezing temperatures
will once again be a forecast challenge for areas that have not
had a freeze yet, especially for coastal areas. Cold weather
advisories for wind chill may also be a factor with winds around
around 5-15 mph and minimum temperatures in the lower to mid 30s.
Massive 500mb ridge appears to flatten out Friday and into next
weekend. WPC ensemble clusters do show about an even split (50%)
of clusters that are "wetter" (at least for the North Coast) than
the grand ensemble mean. The ensemble mean is by no stretch very
wet with 0.10 inches of rain in 24 hours ending 4 PM Sat for
mostly Del Norte. It could be wet or it could be dry or both. Stay
tuned. /ZVS&DUG
&&
.AVIATION...Mostly VFR to sporadic MVFR ceilings have
arrived along the coast overnight. Model generally suggest similar
conditions, with a very slight risk (30% chance) of IFR ceilings
early Sunday, but building offshore flow will most likely help clear
conditions to VFR even before sunrise. VFR conditions will most
likely continue to intensify through the day Sunday as skies clear,
with the vast majority of ensembles (90%) pointing to VFR conditions
through Sunday night into Monday. /JHW
&&
.MARINE...Currently moderate northerly winds in the outer waters
will continue to increase through the day Sunday with near gale
force gusts up to 30 kts by later int he evening. The inner waters
will remain markedly calmer with few gusts over 15 kts near shore.
Northerly winds will shunt further offshore by Monday afternoon, but
there is good agreement that winds will rapidly return around mid
week and push more into the inner waters with high chances (70%) of
gale force conditions.
Aside from the winds, a minor mid period westerly around 8 feet is
currently impacting the waters and will quickly decay Sunday.
Another, much longer period swell will build around Monday into
Tuesday up to around 12 feet. Neither swell will be particularly
steep but will dominate the inner water sea state where short period
seas are calm. /JHW
&&
.BEACH HAZARDS...A mid period westerly swell is currently generating
a minor sneaker wave risk. This risk will persist into the morning
but will quickly decrease through the day. A long period swell (up
to 22 seconds) will suddenly build into the waters up to 12 feet
midday Monday and continue into Tuesday. With calm winds near shore,
this swell will pose a high sneaker wave risk with sudden high surf
on beaches in otherwise calm seeming conditions. Take extra care to
keep distance from the water. Building short period seas and
shortening swell period will decrease the risk by Tuesday afternoon.
/JHW
&&
.COASTAL FLOODING...King Tides return on Tuesday. High astronomical
tides are predicted from Tuesday through Sunday for Northwest
California. The combination of a high astronomical tides and
steep, short-period northerly waves will increase the risk of
minor coastal flooding around Humboldt Bay on Wednesday,
including King Salmon and low-lying roads near Arcata Bottoms.
Minor flooding potential in low-lying areas around Humboldt Bay,
and along much of the coast is then expected through next Sunday.

.UPDATE...
Updated Aviation and Air Quality Issues Sections.
&&
.KEY MESSAGES...
1. Stratus will continue to hang around through most of
Saturday.
2. Trough slides to the east late Saturday through Tuesday.
Winds increase but will bring no precipitation to the area.
3. A second trough slides down Tuesday through Thursday.
Precipitation chances increase for this trough.
&&
.DISCUSSION...
Stratus has continued to hang around which kept temperatures
cold again yesterday. However, ensembles show the ridge
crumbling and breaking as two troughs are in play. One of them
becomes a cutoff low later today but will spin offshore and move
away towards Hawaii. However, the other trough we have been
keeping an eye on will also begin sliding in later today through
the weekend. This trough will help increase wind gusts by a few
miles per hour but not to Advisory level or cause Mono winds for
our area. This trough moves east quickly and will not bring any
rain or snow to our area.
The next chance of rain and snow is another trough which slides
down late Tuesday through Thursday. However, models diverge
around Thursday as to whether this trough will become a cutoff
low or move east. Latest probabilities have a 5 percent chance
or less of an inch of snow in the Sierra Nevada with this storm
and a 20 to 25 percent chance of any rain accumulating in the
Valley Thursday into Friday.
&&
.AVIATION...
IFR to MVFR ceilings and visibilities will persist in most
Valley locations through 18Z Sunday. However, after 18Z,
conditions are expected to improve although there is a 40 to 60
percent chance of ceilings at or below 1,000 feet until 21Z.
After 21Z, there is a 35 to 45 percent chance of ceilings below
3,000 feet.

Area Forecast Discussion...UPDATED
National Weather Service Los Angeles/Oxnard CA
827 PM PST Sat Nov 29 2025
.SYNOPSIS...29/726 PM.
A cooling trend will continue through the weekend as onshore flow
returns. Warming is expected Monday as the flow pattern shifts to
offshore with gusty Santa Ana winds possible. A cooling trend
will develop Tuesday and Wednesday as a storm system approaches
the region. There is a chance of rain Wednesday through Thursday,
mainly south of Point of Conception.
&&
.SHORT TERM (SAT-TUE)...29/826 PM.
***UPDATE***
Low clouds have developed along the Central Coast, and are
expected to become widespread across all coasts and valleys
tonight through at least tomorrow morning. The marine layer is
currently around 700 feet deep at LAX airport and 1000 feet deep
at Vandenberg, an indicator that areas most likely to see dense
fog are locations away from the coast and elevated several hundred
feet above sea level (such as the San Fernando and San Gabriel
Valleys). Onshore flow Sunday may maintain clouds across much of
LA and Ventura Counties through the day.
***From Previous Discussion***
A shortwave ridge of high pressure aloft is starting to breakdown
as an upper-level trough of low pressure off the California coast
digs south offshore. Broader troughing aloft across much of the
Western States will bring a cooling trend as a colder air mass
from Canada pipes air from the north into the region through
Sunday. A return of low clouds and fog is expected tonight and
into Sunday morning as onshore flow will remain intact through
tonight.
As the trough axis slides by to the south, an offshore flow
pattern will develop. A colder air mass in the Great Basin will
set up high pressure near the surface and tighten the surface
gradient between the low pressure system offshore. There is a
moderate-to-high (30-50 percent) chance that advisory level
northeast winds will develop across the region between Sunday
night and Monday morning. The highest chance of gusty offshore
winds is placed with Santa Ana winds across the Southland, but
gusty Santa Lucia winds in San Luis Obispo County cannot be
ruled out. EPS ensemble wind gust means lean toward advisory
levels at typical sites like KCMA and K3A6, while multi-model
high-resolution ensembles fall inline with this idea. A wind
advisory for gusty Santa Ana winds was collaborated with
surrounding offices, but given the uncertainty, the best approach
was to wait and let a few more model runs handle it.
With offshore flow pattern slated to develop and the trough likely
to pull farther offshore, a warmer weather pattern will likely
develop across the region for Monday as compressional heating will
take place. As a result, a dry and warm day should be expected
for Monday.
A cold night looks to be setting up on Monday night and into
Tuesday morning. A northerly flow pattern aloft will likely
redevelop. With less winds, a drier air mass in place, and less
cloud coverage, radiative cooling processes will much more
efficient overnight Monday and into Tuesday morning. In wind-
sheltered areas, such as the interior valleys, there is a
moderate-to-high chance that a freeze watch may be needed as
overnight low temperatures could plummet to between 28 and 32
degrees in these areas.
The pattern will likely switch back to onshore on Tuesday as an
inside-slider type trough digs south out of Canada. A cooling
trend should be expected as onshore pressure gradients develop and
offshore flow breaks down.
.LONG TERM (WED-SAT)...29/133 PM.
The inside-slider trough will move into the region between
Wednesday and Thursday. There is a lot of uncertainty given the
cutoff nature of the system. While EPS forecast ensembles lean
wetter with the system than the forecast, the CMC and GEFS
solutions lean drier. EPS member solutions are starting to lean
drier and produce less precipitation in the current run relative
to last several. Given the time of year and the nature of the
trough, amounts with this storm will very likely be light at best.
A colder, showery, and windy pattern seems to be more of the story
with this system, but any changes in movement either farther
offshore or farther inland will produce different results.
Regardless, a much cooler air mass should be expected for
Wednesday and Thursday along with breezy to gusty winds. Frost
and freeze headlines will likely be needed either on Wednesday
night or Thursday night.
The latest forecast ensembles trend toward a warming trend for
the end of next week, but the air mass will likely to take a few
days to recover. A cold start to Friday morning could linger as a
colder and drier air mass will continue. CMC temperatures mean
suggest the coldest day of the stretch occurring on Thursday night
through Friday morning.
&&
.AVIATION...30/0333Z.
At 0022Z at KLAX, the marine layer was around 1000 feet deep. The
top of the inversion was near 2200 feet with a temperature of 17
degrees Celsius.
For the 00Z TAF package, overall moderate confidence in
forecasts. High confidence in VFR conditions for KWJF and KPMD,
with moderate to high confidence in KBUR and KVNY where there is a
20% chance of LIFR conds overnight. For coastal sites, moderate
confidence in current forecasts due to uncertainties with the
behavior of the marine layer. Timing of flight category changes
could be +/- 3 hours of current forecast with flight categories
off by 1 category.
KLAX...Moderate confidence in the 00Z TAF. Timing of flight
category changes could be +/- 3 hours of current forecasts. Also,
there is a 20% chance of LIFR conditions 08Z-14Z, and a 30% chance
of MVFR conds. No significant easterly wind component is
expected.
KBUR...Moderate confidence in the 00Z TAF. There is a 30-40%
chance that VFR conds prevail through the period.
&&
.MARINE...29/735 PM.
For the Outer Waters, moderate to high confidence in current
forecast. Through Sunday morning, high confidence in winds and
seas remaining below Small Craft Advisory (SCA) levels. Sunday
afternoon through Monday morning, there is a 30-50% chance of SCA
level winds. From Monday afternoon through Tuesday afternoon, high
confidence in winds and seas remaining below SCA levels. For
Wednesday, there is a 20-30% chance of SCA level winds. On
Thursday, high confidence in winds and seas remaining below SCA
levels.
For the Inner Waters north of Point Sal, high confidence in
current forecast. Winds and seas are expected to remain below SCA
levels through Thursday.
For the Inner Waters south of Point Conception, moderate to high
confidence in current forecast. Today through Thursday, winds and
seas are expected to generally remain below SCA levels. The only
exception will be on Monday with a 30-40% chance of SCA level
northeast winds from Ventura south to Santa Monica.

208 PM PST Sat Nov 29 2025
.KEY MESSAGES...
- Dry conditions and possible periods of morning Valley and
adjacent foothills fog and mist continue through Sunday
- Below normal temperatures and low clouds continue in the
Valley, Delta and lower foothills through Sunday, with sunny
skies and above normal temperatures in the upper foothills and
mountains
- Decreasing chances for precipitation with just a slight chance
of snow showers for the Sierra south of I-80 mid-week
- Periodically breezy north to east winds expected late Sunday
through Monday and again mid-week, strongest on Wednesday
&&
.DISCUSSION...
...Today - Sunday... A broad area of low clouds continues to
cover the Delta, Valley, and adjacent lower foothills this
afternoon as a strong inversion persists over the area. This
cloud coverage has kept temperatures quite cool in those areas
once again for today, 10-15 degrees below normal for this time of
year, while higher elevations have been sunny and seasonably mild.
The low clouds also greatly limited the development of fog last
night into this morning, with patchy dense fog mainly limited to
the lower Motherlode foothills and for portions of the northern
Sacramento Valley. This fog diminished by late morning, with some
mist and haze persisting into the afternoon. Dense fog may return
locally to some portions of the area this evening into Saturday
morning, likely the same areas as last night. The persistent low
cloud cover will likely be a limiting factor again for fog
development. Probabilities of fog (visibilities less than a half
mile) currently sit around 50 to 70 percent for the northern and
central Sacramento Valley and the lower foothills, while the
Delta, southern Sacramento Valley, northern San Joaquin have
probabilities around 30 to 50 percent. Aside from periodic fog
development and low clouds, cool Valley/Delta temperatures and dry
weather are expected to persist through Sunday.
...Next Week... Breezy north to east winds will be possible
late Sunday into Monday, around 15 to 20 mph in the Valley, with
the strongest wind gusts up to 30 to 40 mph expected along the
Sierra. With a more persistent offshore(north-east) wind pattern
setting up early next week, fog and low cloud development is
expected to be less relative to this past week. More normal
temperatures are expected with increased sunshine over the
Valley. Ensemble guidance then indicates increasing confidence for
an inside slider type system dropping into the Great Basin,
bringing the potential for breezier north to east winds. Gusts
have trended a little stronger, 25 to 35 mph over the western side
of the Valley, up to 45 mph over the Sierra. There remains a
slight chance for mountain snow showers over the Sierra south of
I-80, but moisture looks very limited with this system so even
high elevations should see just a dusting of snow.
&&
.AVIATION...
Mist lingers through the afternoon hours, with improvements to
ceilings and visibility by the evening. During the evening
ceilings reaching MVFR, but go IFR/LIFR later in the evening and
overnight as the fog redevelops in the Valley. Light and variable
winds will continue through the TAF period. Near the end of the
TAF period, winds will start to shift toward the north at 5-10kts
helping to improve ceilings, visibility, and cloud coverage.

Area Forecast Discussion
National Weather Service San Diego CA
205 AM PST Sun Nov 30 2025
.SYNOPSIS...
Dry and cool today. The marine layer deepens into Monday for more
widespread low clouds and fog each night and morning. Weak to
locally moderate Santa Ana winds develop Monday and weaken Tuesday
with warmer and drier weather. There is a 15-30% chance of light
precipitation Wednesday afternoon into Thursday morning, followed
by another round of weak to moderate Santa Ana winds Thursday into
Friday. Gradual warming Thursday through the weekend with highs
near seasonal normals.
&&
.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...
Morning water vapor imagery shows an upper level trough beginning
to dig southeast across the northern Great Basin and another upper
level low well of the So Cal coast. The digging trough has allowed
the marine layer to deepen, with low clouds extending into the the
inland San Diego County valleys, though coverage across Orange
County remains sparse. Localized dense fog is possible along the
inland extent of the cloud deck. Clouds will clear back to the
coast by late morning with otherwise mostly clear skies today.
Increasing onshore flow with the trough passing by to the north
will bring breezy west winds to the mountains and deserts,
strongest through the passes and on the east facing mountain
slopes where gusts 35-45 mph are possible this afternoon and
evening. The passing trough will also result in cooler weather
with highs near seasonal normals.
The marine layer continues to deepen tonight, potentially
spreading into the Inland Empire. Surface high pressure builds
over the Great Basin tonight behind the departing trough, driving
weak to locally moderate Santa Ana winds by Monday morning. Winds
peak during the morning and early afternoon with gusts 30-45 mph
below the passes, canyons, and foothills. These winds will bring
minor warming west of the mountains where highs will be a couple
degrees above normal, with cooling in the mountains and deserts
due to cold air advection from the north. Surface pressure
gradients and winds weaken on Tuesday, with a return of weak
onshore flow by the afternoon for slight cooling west of the
mountains and slight warming in the mountains and deserts.
For the midweek system, all of the global ensembles and
deterministic models have trended more towards an inside track.
By Thursday, only about 36% percent of the members maintain the
closed low or deep trough over So Cal on Thursday compared to 75%
from the 00Z Saturday runs. The trough still tracks close enough
to maintain a 15-30% chance of showers Wednesday afternoon through
Thursday morning, though with the trend towards the more inside
track, precipitation amounts have decreased. NBM currently has
around a 25% chance of 0.10" or more. Precipitation (assuming we
get any) shuts off pretty quickly on Thursday as another round of
weak to moderate Santa Ana winds develop behind the trough. Santa
Ana winds will likely continue into Friday. For next weekend,
ensemble solutions begin to diverge slightly. Around two-thrids of
the members maintain a ridge just off the West Coast and dry
northwesterly flow over So Cal which would result in warmer
weather and perhaps another round of offshore flow, while the
remaining members break the ridge down and have more zonal flow
for cooler weather and more persistent onshore flow.
&&
.AVIATION...
300930Z....Coasts/Valleys...Patchy low clouds with bases around 400-
1500 ft MSL have moved ashore this evening and into the San Diego
Valley. Visibilities have been higher than the previous
evening/morning. Bases will likely rise slightly through 13Z to
around 700-1500 ft MSL, allowing a 40% chance for CIGs/FG vcnty at
KONT around 13-18Z. Clouds will clear to the coast in most areas by
15-17Z. Low clouds will redevelop with bases of 900-1500 ft MSL and
move ashore again after 01Z Monday.
.Mountains/Deserts...VFR conditions are expected through the TAF
period. Strong surface winds gusting 25-35 kt, up to 45 kt through
wind-prone passes, at times in the deserts and eastern mountain
slopes, generally after 18Z through Sunday evening. Moderate
up/downdrafts expected in the vicinity of the mountains. Winds
becoming offshore and breezy after 12Z Monday morning for the west
mtn foothills locally into eastern valleys, with local areas of LLWS
possible for parts of the valleys.

.SHORT TERM...
Issued at 103 AM PST Sun Nov 30 2025
(Today and tonight)
High clouds make life for the meteorologist a little difficult this
morning, as it blocks the low level clouds that are being
observed in the North Bay, East Bay, and San Francisco region. The
question for today, is, you guessed it, much like yesterday and
pertains to if or when will the clouds clear out around there.
Guidance favors perhaps a few hours earlier today, perhaps the
early afternoon hours instead of the mid to late. Given that,
opted to go with slightly higher temperature forecast than
yesterday's observed temperatures for the N Bay and surrounding
areas. Highs will still be below normal there by about 0 to 10
degrees, while the rest of the region is closer to normal for this
time of year.

The forecast remains on track for the extended period, with the
first feature being stratus clearing out for the North and East Bays
Monday and Tuesday afternoon. An inside slider remains on tap for
midweek, which will bring breezy conditions to the interior North
Bay hills Wednesday morning. Conditions will dry out as well in
terms of minRH values; however, no major fire weather concerns are
expected. Beyond that, the slider looks to dig south, which should
allow for upper level ridging to build towards us. Dry weather
