Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
424 PM AKST Sun Nov 7 2021

.ANALYSIS AND UPPER LEVELS...

An upper-level trough is positioned over the Southwest and is
extending into the southern Gulf of Alaska. Shortwaves embedded in
the larger trough are progressing east to west across
Southcentral with two distinct waves progressing towards Kodiak as
a result of the easterly flow. Radar is showing returns over
western Prince William Sound, Cook Inlet, and the Susitna Valley.
As these waves move west across Southcentral, satellite imagery is
showing signs of clearing across the Copper River Basin and
northeastern Gulf of Alaska. Out west, a jet stream is draped from
Russia southward across the Bering and through the Alaska
Peninsula. A ridge of high pressure is positioned over the eastern
Aleutians and extends to the Alaska Peninsula while a large
upper-level low is located southwest of Attu, is amplifying the
ridge and overall pattern to pull more cold arctic air south
towards the Alaska Peninsula. Satellite is showing cloud streets
forming over Bristol Bay and south of the Alaska Peninsula as a
result of the cold unstable air moving south and wrapping into
the upper-level trough positioned over the Gulf.

&&

.MODEL DISCUSSION...

Models are in good overall synoptic agreement through the
forecast period. However, models are struggling with the timing of
shortwaves that will pass over Kodiak today and how fast they
will progress, but, overall, there is agreement that these waves
will progress west towards that location. A low and associated
front moving into the Aleutians is also being handled well with
good agreement of its slow eastward progress and eventual dip
southward into the North Pacific later in the week. Overall,
forecast confidence is good.

&&

.AVIATION...
PANC...MVFR conditions will likely prevail through mid to late
afternoon before VFR conditions are expected to return. There will
likely be some low clouds (around 1,000 ft) lingering across the
Anchorage Bowl and Cook Inlet overnight. Right now, given the
light northerly winds, these low clouds are not expected to move
over the terminal.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3)...

A trough anchored to a low over the western Gulf combined with
cold air advection over Kenai Peninsula is producing light
snow over the northern Kenai Peninsula including Soldotna this
afternoon. This same trough will direct snow showers through
Kodiak Island tonight and Mon. Meanwhile, another developing
trough connected to a North Pacific low will migrate westward
bringing another round of light snow near the Kenai Peninsula and
Kodiak Island on Tue. A cold airmass over Southcentral will favor
snow over rain from the Copper River Basin through the Anchorage
Bowl northward through the short term.

Low clouds/stratus remains over Copper River Basin this
afternoon. This pattern could continue for the next couple days
as the ridge aloft builds northward and across Southcentral into
Tue afternoon. Radiational fog could appear in other parts of
Southcentral as temperatures continue to drop matching up with
the dewpoints the next few days. The Arctic airmass will
predominate the northern and eastern parts of Southcentral,
leading to plunging temperatures with most overnight lows reaching
the single digits through the middle of the week. Overall, a
relatively dry but quiet forecast is expected over much of
Southcentral through the short term.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 through 3: Tonight
through Wednesday)...

Cool temperatures across the area will continue under northerly
flow across the region. More cold air will filter through the
Kuskokwim Delta for the early half of this week as an upper low
dips south over Nunivak and towards Bristol Bay. Low temperatures
inland could dip below zero on Wednesday morning. Slight chances
for snow showers are expected to remain primarily offshore.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 through 3:
Tonight through Wednesday)...

The persistent high amplitude ridge over the Central Bering and
Aleutians will begin to break down as the next, more energetic
low from Kamchatka heads towards the Western Aleutians and
interacts with the decaying low currently situated west of
Shemya. Look for rain and mixed precipitation with the frontal
passage from east to west. Model guidance breaks down on the
extent of precipitation going eastward into midweek as this low
disrupts the general flow pattern and determines how amplified
this trough gets.

&&

.MARINE (Days 3 through 5: Wednesday through Friday)...

Aleutians/Bering...An elongated area of low pressure moving south
of the Aleutian Islands early Wednesday will exit into the North
Pacific. Portions of the front on the northern side of this low
may reach gale force in the vicinity of the Central and Eastern
Aleutians. In the wake of the departing low, gap winds will
develop through the Eastern Aleutians and Alaska Peninsula which
will have the potential to locally reach gale force. Seas are
expected to remain less than 20 ft through the Day 3 through 5
period.

Gulf of Alaska...A low tracking into the Gulf Thursday night is
likely to produce a large area of gale force winds wrapping its
center in the central Gulf through Friday. Gap winds develop in
the western Gulf Friday morning with the potential to reach gale
force. Seas are expected to remain less than 20 ft.

&&

.LONG TERM FORECAST (Days 4 through 7: Thursday through
Sunday)...

Mainland Alaska will sit at the center of a highly amplified
longwave trough on Thursday which will produce relatively quiet
and cool conditions for much of the forecast area. However,
significant uncertainty remains with the placement of individual
features within this pattern. A large embedded upper-level low may
produce snow over Southwest Alaska on Thursday, before model
solutions diverge on its evolution. The GFS and Canadian have this
low diving southward, leaving a weaker trough in place, while the
EC keeps it lingering over the mainland, though snowfall rates
decrease. Synoptically, there is good agreement that a surface low
will enter the Gulf late Thursday, however its track depends on
the evolution of the upper low over the Southwest. The GFS and
Canadian solutions track the low into the eastern Gulf, with less
to draw it westward, and keeping impacts minimal beyond gap winds.
However, the EC brings the low ashore on the north Gulf Coast,
leading to coastal precipitation from the eastern Kenai Peninsula
eastward.

A stout ridge pushes eastward across the Bering through
the weekend, where conditions remain fairly calm. Cold air and an
accompanying shortwave trough ride atop it into mainland Alaska,
introducing some potential for another round of colder
temperatures late this weekend. However, there are significant
model differences with the strength of this trough. GFS depicts a
stronger feature driving cold Arctic air across the Alaska Range
and dropping 850 mb temperatures to near -13C over Anchorage
Saturday night, while the Canadian shows a weaker feature with
less cold air. The EC instead resolves a separate deep shortwave
which brings temperatures below -10C over Southcentral.
