Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
507 AM AKST Tue Dec 30 2025

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3/Today
through Thursday night)...

The large scale pattern is right back where it has been for
nearly all of December, with a high amplitude blocking ridge
parked over the central Bering Sea. A corresponding high amplitude
trough is positioned over Southcentral, the Gulf of AK, and the
Northeast Pacific. It is anchored by a closed low aloft, with
numerous short-waves and surface lows embedded within the cyclonic
circulation. Most of the precipitation is now confined to the
Gulf waters and Kodiak Island, though some showers are making it
onshore along the North Gulf coast and Prince William Sound. In
particular, easterly low level flow is enhancing snowfall over
western Prince William Sound and portions of the Eastern Kenai
Peninsula. Automated snow depth sensors indicate anywhere from 2
to 9 inches of snow has fallen across this region in the past 24
hours. The intrusion of the Gulf trough into Southcentral has
allowed winds to diminish across the region, though there are
still locally strong and gusty winds through the coastal mountain
gaps. This is leading to localized areas of blowing snow,
including through Thompson Pass. Bands of snow have rotated off
the Gulf into Kodiak Island, leading to snow and blowing snow. It
dies appear the heaviest snow is remaining offshore, sparing
Kodiak City from worse conditions. Winter Weather Advisories are
in effect for both Thompson Pass and the northeast end of Kodiak
Island for low visibilities in blowing snow.

The upper low anchoring the trough will track toward Southeast AK
today, pulling the entire cyclonic circulation with it and
bringing an end to snowfall across Kodiak and Southcentral. With
the shift in flow and pressure gradient orientation, westerly
winds will rapidly strengthen in Whittier and easily blow around
the low density snow currently falling. Thus, a Blizzard Warning
has been issued for Whittier beginning 11am this morning.

Attention then shifts to a potent short-wave crossing the top of
the Bering ridge. It will dig southeastward across Southwest AK
today and into the western Gulf tonight into Wednesday, bringing
another round of cold air advection and winds with it. The area of
strongest advection will be across the Alaska Peninsula, the
western Gulf coastal waters, and Kodiak Island. Have upped winds
in the latest forecast, with wind gusts of 50 to 70 mph expected,
strongest through channeled terrain.

Meanwhile, a much weaker short-wave trough over interior AK, will
dig southeastward just ahead of the Bering short-wave. It will
cross Southcentral from west to east this afternoon through
Wednesday. There may be some flurries or very light snow right
ahead of it as it crosses interior Southcentral, but forcing is
weak and the air mass is dry so it won't be much. The northern end
of the much stronger short-wave will slowly approach Southcentral
Wednesday and looks increasingly likely to generate light snow
from Prince William Sound across the Cordova/Valdez areas and
northward into the Copper River Basin. This snow will then exit
eastward to McCarthy and the far eastern Copper Basin Wednesday
night as the upper trough marches eastward. There could be some
localized areas of blowing snow and reduced visibilities, most
notably through Thompson Pass and Valdez on Wednesday.

The bigger story will be the reinforcing shot of Arctic air
accompany these short-waves. This will cause gap winds to
restrengthen, especially along the western Alaska Range and
the north Gulf coast and Prince William Sound. Upper level flow
will be out of the northwest, which is much different than most
of the windstorms of the past month. Thus, strong winds will be
confined mostly to bays and passes and will not be as widespread.
Thankfully, this pattern is NOT favorable for the Matanuska Valley
where winds in Palmer and Wasilla will be fairly light. Dry and
very cold conditions will settle back over the region as we begin
the new year.

.SHORT TERM FORECAST SOUTHWEST ALASKA/BERING SEA/ALEUTIANS (Days
1 through 3: Today through Thursday)...

The large scale pattern in place across the Bering and Southwest
is little changed compared to yesterday. A stout upper ridge is
making slow but steady progress eastwards this morning, allowing
relatively light winds and dry conditions to spread across the
central/eastern Aleutians and Pribilofs. Farther west, a front
associated with an North Pacific low is approaching the western
Aleutians from the south, spreading low-end Gale force winds into
western parts of the Chain. Across the AKPen, very strong and
gusty north winds persist this morning, fueled by strong northerly
flow between the Bering ridge and a deep low meandering across the
Gulf. The strongest winds have been reaching Storm force at times
along the Pacific side of the AKPen, recently captured by
multiple remote sensing instruments, including a couple synthetic
aperture radar (SAR) passes. Areas of resuspended dust and ash
from a few volcanoes lining the southern AKPen continue to show up
intermittently thanks to the strong northerly winds. Across the
remainder of Southwest, clear, cold and windy conditions persist
by and large.

For the near term outlook, no major changes have been made from
prior expectations. The Bering front will continue to make steady
northeast progress into the western and central Bering through
midweek, spreading mainly rain across the Aleutian Chain as it
moves across. Precipitation could start out as snow in the
Pribilofs as the front moves in Wednesday afternoon, but a fairly
quick transition to rain is likely by Wednesday evening. as warmer
air along the boundary pushes through.

Across Southwest, a weak low and trailing front currently moving
across the far northern Bering is on track to push a quick shot of
snow showers across the Kuskokwim Delta this evening into early
Wednesday. Moisture support for snow along this incoming front
still looks unimpressive, with perhaps as much as a quick inch of
new snowfall anticipated as the front races past tonight. Across
the rest of Southwest, cold and dry conditions will persist
through Thursday as north winds gradually die down. For the Alaska
Peninsula region, very strong and gusty northerly winds will
continue today, weakening slightly by Wednesday, then coming down
more sharply by Thursday as the Bering ridge erodes and as the
Gulf low weakens.

.LONG TERM FORECAST (Days 4 through 7: Friday through Monday)...

A rex block will be in place at the start of the long term
forecast period with ridging over the central Bering Sea and
troughing over mainland Alaska and the western Bering Sea. Cold
temperatures will descend over southern Alaska where areas of the
Kuskokwim Delta may see temperatures as low as 40 below zero. Most
of mainland will be under dry conditions while the Aleutians
continue a showery regime.

The main weather maker at the end of the weekend will be an
Aleutian low as it progresses eastward and breaks down the Bering
ridge. Deterministic models are in fairly good agreement for being
this far out in time, currently prognosticating between 950 to
960 mb as it moves into the Bering Sea on Sunday. Expect high
winds to possible storm-force as this system traverses over the
Chain. Moderate to heavy precipitation looks likely as moist
southerly flow associated with the frontal system moves over
southern Alaska. This will be one to keep an eye on going forward.

&&

.AVIATION...

PANC...Gusty winds will finally die down today, slowly diminishing
through the morning hours. A weak upper short-wave digging into
Southcentral from the Interior tonight, will keep some clouds
overhead, though mostly mid to high clouds. There is a just a
slight chance of ceilings dropping to 5000 feet or a bit lower
as the trough crosses overhead between 09Z and 15Z.

SPECIAL WEATHER STATEMENT
National Weather Service ANCHORAGE AK
333 PM AKST Tue Dec 30 2025

AKZ772-311400-
Kodiak Island Southwest-
Including the cities of Old Harbor, Akhiok, Karluk,
and Larsen Bay
333 PM AKST Tue Dec 30 2025

...RESUSPENDED ASH FROM KATMAI-NOVARUPTA EXPECTED OVER SOUTHERN
AND WESTERN KODIAK ISLAND THROUGH WEDNESDAY NIGHT...

Strong northwesterly winds with gusts up to 55 mph have developed
across Shelikof Strait. The wind is resuspending ash from the
1912 Katmai-Novarupta eruption and transporting the ash across
Shelikof Strait and southwest Kodiak Island. Resuspended ash will
will lead to hazy conditions and may also lead to trace amounts of
ash accumulation. The villages of Karluk, Larsen Bay, and Akhiok
are most likely to be impacted.

Those with respiratory ailments in these areas are encouraged to
avoid or reduce outdoor activity to avoid inhaling the ash. The
winds are expected to diminish starting Wednesday evening, which
should allow any ash to settle out of the air.
