AREA FORECAST DISCUSSION
National Weather Service Eureka CA
153 PM PDT Mon Oct 27 2025
.SYNOPSIS...High pressure is building in to the area, bringing dry
weather for much of the week. A chilly night is forecast tonight,
with potentially freezing temperatures in Trinity County. Drizzle
possible for the coastal areas Wednesday. Slight chance for rain
this weekend.
&&
.DISCUSSION...High pressure has started to build back into the area
after a soggy weekend. Abundant cloudiness in the interior
valleys have slowly started to scatter out early this afternoon.
Despite these clouds, temperatures this morning fell into the 30s
across the area, including along the coast. Cloud cover over the
interior valleys will limit warming potential today, with some
areas struggling to even reach the 60s. Despite warming
temperatures aloft, residual cloud cover today and continued
drying could support a colder night tonight for the interior
valleys. Coastal temperatures are likely to rise a few degrees
tonight, so frost is unlikely to be a concern. However, the
interior valleys may end up colder, in the high 20s to low 30s, as
skies clear tonight. A Freeze Warning has been issued for early
Tuesday Morning for the valleys of Trinity County, including
Hayfork and Weaverville. A Frost Advisory has been issued for
northern interior Mendocino County, which includes Willits and
Laytonville. Protect any sensitive plants.
By Tuesday, warmer temperatures are forecast for the interior as
high pressure finally builds in with mostly clear skies. Despite the
chilly morning, high temperatures are forecast to be in the 70s with
nearly 80 possible in some of the warmest valleys. A weak front
moves to the north of us Tuesday night into Wednesday. This may
bring some drizzle or light showers to the North Coast, but high
cloud cover looks like the biggest impact. Temperatures are forecast
to remain nice in the interior Wednesday, with 70s or 80s for most
valleys.
Ridging begins to weaken late week into the weekend as a series of
troughs approaches the Pacific Northwest. Confidence is low on if
any of these troughs will reach far enough south to bring us
precipitation. Ensemble clusters are fairly confident in keeping us
with above normal 500 mb heights through the weekend. Still, NBM
probabilities of a tenth inch of rain on Saturday are above 50% in
Del Norte and above 30% along the northern Humboldt coast.
Probabilities for 1 inch drop off to around 20% in Del Norte.
Ensemble members are showing additional chances for rainfall into
early November. The CPC 8-14 day precipitation outlook highlights
northwestern California for above normal precipitation. JB
&&
.AVIATION...(18Z TAFS)...VFR generally expected with occasional
broken to overcast mid to high level clouds above 10,000 feet for
North Coast aerodromes. Brief MVFR vsby in 3-5SM in mist possible
(20% chance) aft 06z for KCEC and KACV. E-SE breezes below 5 kt
will reduce the potential for IFR at coastal forecast terminals.
VFR is expected at KUKI with drier dewpoints and light offshore
breezes through the night.
&&
.MARINE...Brisk northerly winds and steep wind waves will continue
to bring hazardous conditions for small craft in the southern waters
tonight into Tuesday. Northerly winds and large steep seas increase
Wed both north and south of the Cape after passage of front into the
Pac NW. Winds should diminish Thu and Fri with the approach another
front from the NW. Seas will likely remain steep and elevated into
at least Thu due to a combination of wind waves and swell.
&&
.BEACH HAZARDS...Series of W-NW swell groups will spread into the
waters through the week. First swell is forecast to arrive on Wed
with peak wave periods near 15-16 second. Wave spectrum appears
quite noisy with multiple shorter period energy bands and steeper
northerly wind waves offshore. The sneaker wave threat for this
first swell appears quite low at the moment. A second swell group
with much longer periods (+20 seconds) will arrive late Fri and
build through Sat. This swell, if it materializes, will pose a
greater risk for sneaker waves and large surf. Deep waters swell may
eventually become too large on Saturday with elevated surf notably
hazardous to beachgoers.

.KEY MESSAGES...
1. Gusty winds will continue until late tonight along the Mojave
Desert slopes in eastern Kern County.
2. A warming trend will bring above average temperatures by
midweek. Warm temperatures may last until at least the weekend.
&&
.DISCUSSION...
We will experience one more relatively cool day in the wake of
the upper-level trough that passed over the area. Meanwhile, gusty
winds will continue along the Mojave Desert slopes until early
this morning, as short-term high resolution guidance shows 45-50
mph winds persisting overnight tonight, including probabilities
as much as 50-60 percent for gusts at least 45 mph for at least
the next few hours. Dry conditions will prevail with a warming
trend beginning Tuesday. Near to above average temperatures are
likely by Wednesday, as the chances for highs in the 80's in the
warmest valley and desert locations increase markedly.
Probabilities for a high of 80 degrees in the San Joaquin Valley
are around 30-40 percent, while the chances are significantly
higher in the Kern County desert, or at 80-90 percent. This is
due to a building ridge of high pressure over much of the
Western U.S. Similar probabilities are shown through the end of
this week into the weekend, or the first weekend of November. We
are not forecasting precipitation for the next seven days.
The Climate Prediction Center shows an 80-90 percent chance of
above average temperatures continuing in the 6-10 day period and
70-80 percent chance for the 8-14 day period. Although, for
both of these periods, near average precipitation is projected.
Climatologically speaking, average precipitation is generally
relatively low in early November.
&&
.AVIATION...
Mainly VFR conditions will prevail throughout the Central CA
interior for the next 24 hours. Except MVFR visibility with
local IFR until 18Z Monday in the San Joaquin Valley.

Area Forecast Discussion...UPDATED
National Weather Service Los Angeles/Oxnard CA
818 PM PDT Mon Oct 27 2025
.SYNOPSIS...27/909 AM.
The first Santa Ana Wind event of the season is expected Tuesday
and Wednesday, bringing very warm temperatures to the coasts and
valleys and gusty winds to the typically wind prone corridor of
Los Angeles and Ventura Counties as well as most mountains. Late
this week through the weekend, temperatures will remain above
normal with no rain chances in the foreseeable future.
&&
.SHORT TERM (MON-THU)...27/816 PM.
***UPDATE***
Big switch in the weather underway. Currently there is a 6mb
offshore push from the north and about a 1 mb offshore push from
the east. The trends are impressive as well, with both in the 4 to
5 mb range. This offshore push from the north is generating wind
gusts 35 to 45 mph through the passes and canyons of the Santa
Ynez range. Later tonight advisory level winds will develop
through the i-5 corridor and spill into the Santa Clarita Vly. By
dawn the offshore push from the east will have increased to about
5 mb and this will switch the winds to the NE and the first Santa
Ana wind event of the season will begin. Look for 40 to 50 mph
gusts through the Santa Ana corridor (Santa Clarita Vly to Pt
Mugu).
The Santa Ana winds will also produce a marked warm up. Look for
10 to 15 degrees of warming across all of the csts and vlys. This
will raise max temps for the csts/vlys into the mid 80s to mid 90s
or about 12 degrees above normal. A heat advisory is in effect for
the csts/vlys.
As with all Santa Anas the humidities will be in the single digits
and teens. The combination of low humidities, high temperatures
and gusty winds will produce red flag conditions through the Santa
Ana Wind Corridor.
The current forecast is well on track and no updates are planned.
***From Previous Discussion***
The first Santa Ana Wind event of the season will start Tuesday
(tomorrow) and last through Wednesday, driven by offshore surface
pressure gradients that will set up across the region. A
relatively colder airmass has surged into the Central Valley,
resulting in a surface high to contrast the surface low pressure
along the SoCal Coast (the LAX-DAG and LAX- BFL gradients are
likely to peak around 5 mb offshore). This imbalance will drive
the offshore winds out the northeast over the next couple days.
Expect northeast winds to pick up tonight along the San Luis
Obispo County Santa Lucia Mountains and coastal areas (including
Morro Bay and Cayucos), then developing early Tuesday morning
across the Santa Ana wind prone corridor of Los Angeles and
Ventura Counties. Winds Advisories are in effect the windiest
areas tonight through Tuesday, with additional advisories
possible for late Tuesday night into Wednesday morning (see NPWLOX
for more details).
The warm downsloping winds will lead to temperatures well above
normal temperatures across the region, including the coastal
plains and beaches. Heat Advisories are currently in effect
across much of Ventura and Los Angeles Counties Tuesday through
Wednesday, where daytime highs will be in the upper 80s to low
90s, which is 10 to 15 degrees above normal (see NPWLOX for more
details). Temperatures will approach daily records, especially
near the beaches.
Additionally, the influx of dry air from the interior will yield
very low relative humidities. Gusty winds and these dry
conditions will result in elevated to Critical Fire Weather
conditions, and Red Flag Warnings have been issued for the
Western San Gabriel Mountains, Santa Susana Mountains, and the
Southeastern Ventura County Valleys (see RFWLOX for more details).
Residents in or near theses areas are advised to check for
multiple ways to recieve weather and emergency alerts and make
preparations to evacuate in an emergency wildfire situation.
The Santa Ana winds will keep marine layer clouds at bay for the
next few days, with some low clouds and fog likely to return
Thursday morning. Heat will also let up somewhat on Thursday,
through temperatures will remain above normal with highs in the
80s common.
.LONG TERM (FRI-MON)...27/148 PM.
An extended period of broad ridging is favored to prevail over
the region Friday into early next week, with little variation
between forecast models. This will keep temperatures generally
above normal, though offshore surface pressure gradients are
expected to decrease, which will will allow for a cooling trend
for Friday. The ridge is likely to strengthening over the weekend,
resulting a minor bump in temperatures. At this point, heat
products are not likely to be needed. Additionally, there is
little indication of a pattern change in the foreseeable future,
with the next chance for rain well beyond the forecast period
(late next week in early November).
&&
.AVIATION...27/2340Z.
At 2240Z at KLAX, the marine layer was 900 ft deep. The top of
the inversion was 5000 ft with a temperature of 20 C.
High confidence in KWJF and KPMD TAFs.
Low confidence in low cloud evolution tonight into early tomorrow
morning. LLWS will be a concern at KSBP tonight. NE winds and/or
LLWS will be a concern after 12Z Tuesday at KCMA KOXR KVNY.
KLAX...Moderate to high confidence in VFR conditions through 04Z.
Thereafter, low confidence with a 40% chance for IFR CIGs 005-008
to develop from 09Z to 16Z Tue, with moderate confidence in MVFR
VSBYs 4 to 5SM. No significant east wind component expected.
KBUR...Moderate confidence in TAF. VFR conditions expected
through fcst pd. NE winds will form over the region on Tuesday,
with mdt confidence that they will no surface at airport, but some
weak to moderate LLWS may form.
&&
.MARINE...27/606 PM.
The current NW winds will shift to N-NE through Tuesday. High
confidence in Small Craft Advisory (SCA) winds and seas through
tonight from the Central Coast (including nearshore) to San
Nicolas Island. Localized GALE force wind gusts possible across
an area from Point Conception down to buoy 46069 and about 30 NM
to the west through this evening.
NE winds will impact the nearshore waters Tuesday and Wednesday
morning from Ventura to Santa Monica, & along the Central Coast.
High confidence winds will peak at least in the 15-20 knot range.
There is a 30% chance that winds cross over into SCA criteria in
terms of speed and duration.
NW winds will likely return to SCA levels from the Central Coast
to San Nicolas Island by Thursday.
Patches of dense fog will likely form Thursday into Friday.
&&
.FIRE WEATHER...27/357 PM.
Gusty north winds combined with a drying trend will bring
elevated fire weather conditions through this evening across
portions of the mountains, southern Santa Barbara county, and
Antelope Valley. Late tonight into Wednesday a weak to moderate
Santa Ana wind event will develop across southern California.
Northeast winds gusting 30 to 40 mph will be common on Tuesday
across the typical Santa Ana wind prone corridors of LA/Ventura
counties, with isolated gusts up to 45 mph across favored
mountain/foothills areas. The offshore winds are expected to
diminish some in most areas Tuesday night into Wednesday (with
gusts mostly in the 20 to 35 mph range). However, high resolution
models indicating a secondary burst of wind gusts 35 to 45 mph
late Tuesday night into Wednesday morning across the western San
Gabriels, Santa Susanas, and the Highway 118 corridor of the
eastern Ventura county Valleys (near Moorpark, Simi Valley). This
Santa Ana wind event will be associated with very warm and dry
conditions, especially across coastal/valley areas where downslope
warming will occur. Minimum humidities of 8 to 15 percent will be
common across much of LA/Ventura counties, falling to 5 to 10
percent on Wednesday. In addition, there will be very poor
humidity recoveries on Tuesday night with many wind prone
areas/foothills remaining in the 10 to 20 percent range.
The combination of gusty Santa Ana winds, very warm temperatures,
and very low humidities will bring widespread elevated to brief
critical fire weather conditions across the region Tuesday into
Wednesday, especially wind corridors of LA/Ventura counties where
2 to 5 hours of Red Flag conditions could occur each day. The most
enhanced wind areas on Tuesday and Wednesday (western San Gabriel
mountains, Santa Susanas, and southeast Ventura valleys mainly
near Simi Valley/Moorpark) will likely see 6+ hours of Red Flag
durations, resulting in the issuance of the Red Flag Warning for
the longer duration threat. Despite recent rains, local fire
agencies indicating fuels are still supportive of rapid fire
spread and extreme fire behavior across portions of the forecast
area. Live Fuel Moisture values are still in the 65 to 75 percent
range across much of the area, with only a shallow grass crop
forming in many areas after recent rains. Residents in or near the
Red Flag Warnings ares are advised to check for multiple ways to
recieve weather and emergency alerts and make preparations to
evacuate in an emergency wildfire situation.
Winds will continue to weaken on Thursday, but a light offshore
wind influence will continue to maintain very warm and dry
conditions through the weekend away from the coast.

National Weather Service San Diego CA
153 PM PDT Mon Oct 27 2025
.SYNOPSIS...
Offshore flow and strengthening high pressure aloft will bring
warming through Wednesday with periods of gusty Santa Ana winds
along and below the coastal slopes of the mountains for tonight
into Wednesday with the stronger gusts to 35 to 45 mph. High
temperatures 15 to 20 degrees above normal expected Tuesday and
Wednesday afternoon. Weak onshore flow will bring less hot
conditions inland for Thursday and Friday with high temperatures
for next weekend at least a few degrees warmer as high pressure
aloft strengthens and another weak offshore event appears
possible.
&&
.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...
Today through Wednesday...
As the trough currently over Idaho digs southeastward today,
building high pressure across the Great Basin will strengthen the
offshore pressure gradient. North to northeasterly flow is set to
begin this afternoon across the deserts and desert slopes, while
onshore flow prevails today for the coasts and valleys. This will
likely inhibit the marine layer, with only a few clouds possible
along the coasts tonight. As inland high pressure builds, the
offshore gradient is set to peak on Tuesday, resulting in in weak to
locally moderate strength Santa Ana winds, with strong gusts
primarily focused within and below main mountain passes. Wind gusts
here could gust up to 35 to 45 mph on Tuesday afternoon, with 25-35
mph gusts stretching into the Inland Empire, the Santa Ana
Mountains, and the inland valleys of San Diego County. High pressure
in the Great Basin slides east heading into Wednesday, and while
offshore flow should persist through late Wednesday, wind gusts
should be notably weaker than Tuesday.
Meanwhile, a building ridge paired with the compressional effects of
the downslope, offshore winds and a lack of a marine layer will
culminate in a substantially warmer day on Tuesday compared to
today. Afternoon temperatures are expected to soar into the low to
mid 90s across inland portions of Orange/San Diego counties and
the Inland Empire, coming in about 13-18 degrees above normal for
late October. Despite weaker offshore flow Wednesday, continued
dry conditions and the upper level ridge keeps temperatures hot,
even a degree or two warmer than Tuesday. With this, widespread
moderate HeatRisk is still expected across Orange County inland,
San Diego County valleys, and the Inland Empire, and the Heat
Advisory currently in effect for Tuesday into Wednesday remains on
track. The offshore flow brining in the hot and dry desert air
will also send afternoon humidity into the low teens Tuesday and
Wednesday afternoon. This when combined with the Santa Ana winds
will bring elevated fire weather conditions, and locally critical
conditions during the periods of strongest winds in the afternoon
within wind- prone mountain passes.
Thursday into Late Week...
The offshore pressure gradient relaxes late Wednesday into Thursday,
with onshore flow reestablished for the coasts and valleys by
Thursday afternoon. The absence of offshore flow allows
temperatures to cool some for Thursday, albeit still 5-10 degrees
above normal. Weak ridging remains in place into the end of the
week, keeping the marginally above normal warmth in place. The
marine layer looks to return, at least partially, by Thursday
morning. Another weak offshore wind event is possible this
weekend, which could bring another period of warmer and drier
conditions.
&&
.AVIATION...
262000Z...Coast/Valleys...Mostly clear through the afternoon hours
with lingering HZ and vis 3-5sm across the Inland Empire. Confidence
now moderate to high of BKN cigs near 800-1200 ft MSL returning to
VCTY KSAN/KCRQ 06-16z Tue. Cigs becoming more intermittent after 12Z
Tue. Lower confidence in these cigs impacting VCTY KSNA. N/E winds
with gusts 20-30 kts increasing across parts of the Inland Empire
downwind of the Cajon / Banning Passes after 12Z Tues will lead to

Issued at 1248 PM PDT Mon Oct 27 2025
(This evening through Tuesday)
Satellite imagery shows lingering stratus across the South Bay.
Current thinking is for the cloud cover to last for another couple
of hours. After the stratus mixes out, the skies should remain clear
through the day and the overnight hours, straight through Tuesday.
The weather pattern is in transition today, as zonal flow (west to
east winds) aloft this morning gives way to a building ridge that
will dominate the weather pattern for the rest of the week. Today's
highs remain cool with the inland valleys reaching temperatures in
the lower 70s, with areas along the Bays going into the upper 60s
and the Pacific coast seeing highs in the lower to middle 60s. After
a cool morning with lows in the middle 40s to lower 50s across most
of the lower elevations, a marked warming trend begins on Tuesday as
temperatures rise slightly (5 to 10 degrees) above seasonal
averages, with the inland valleys seeing highs in the upper 70s to
the lower 80s, the bayside regions seeing highs in the lower to
middle 70s, and the Pacific coast hovering around the middle to
upper 60s. The resulting thermal trough over California will combine
with a surface high developing over the northern Rockies to produce
mild offshore flow, with light winds from the north and the
northeast across the higher elevations. The relatively light wind
speeds will keep fire weather concerns in check.

average mark and minor HeatRisk is possible, corresponding to a
slight risk of heat related illness for people highly sensitive to
heat. An incoming trough in the northern tier will restore mainly
onshore flow and cause temperatures to dip across much the region,
with the inland valleys across the Bay Area seeing highs in the
lower to middle 70s and the Bay Area Pacific coast dipping to near
60 while the interior Central Coast continues to see highs in the
80s. Enhanced cloud cover is possible, but any rain chances remain
far to our north across the Pacific Northwest. Temperatures will

The offshore flow persists into Wednesday morning, with a peak in
the temperatures that day as the inland valleys reach the lower to
middle 80s. Temperatures reach the 10-15 degree above seasonal
average mark and minor HeatRisk is possible, corresponding to a
slight risk of heat related illness for people highly sensitive to
heat. An incoming trough in the northern tier will restore mainly
onshore flow and cause temperatures to dip across much the region,
with the inland valleys across the Bay Area seeing highs in the
lower to middle 70s and the Bay Area Pacific coast dipping to near
60 while the interior Central Coast continues to see highs in the
80s. Enhanced cloud cover is possible, but any rain chances remain
far to our north across the Pacific Northwest. Temperatures will
quickly rebound and return to the 5-10 degree above seasonal average
bracket for the upcoming weekend, with CPC outlooks suggesting that
temperature above seasonal averages continue into the first week of
November.
