Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
528 AM AKST Mon Nov 8 2021

.ANALYSIS AND UPPER LEVELS...

An upper level low is in place over the Gulf of Alaska. Several
upper level shortwaves are gradually propagating from east to west
across Southwest, producing some snowfall across the Lower
Kuskokwim Valley. At 300 mb, the jet is well south of the state,
extending across the north Pacific. Farther west over Siberia, a
140 knot jet streak is gradually digging southward, helping to
steer an upper level trough over Kamchatka into the western
Bering. Closer to the surface, low level stratus persists across
Southcentral and Southwest Alaska, as generally weak upper level
flow keeps clouds in place.

&&

.MODEL DISCUSSION...

Model solutions are in good synoptic agreement. In the short term,
the biggest challenge with this forecast is the widespread
low level stratus across the Copper River Basin and Southcentral.
With little upper level forcing, stratus and fog are expected to
stick around. Looking ahead, there is good agreement that a ridge
will approach the western Aleutians midweek while a north Pacific
low lifts into the Gulf. Overall, forecast confidence is average.

&&

.AVIATION...

PANC...Low stratus is expected to linger at least through midday
today, keeping ceilings at IFR. Winds will remain light out of
the north. Ceilings may improve by this evening.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...

With the pattern of a low south of the Gulf and high pressure in
the northwest part of the state, there is now a break in the
active weather. The shortwave moving into Kodiak this morning
looks to have mostly weakened with clouds and little if any
precipitation associated with it. The main weather challenge is
now determining when the low stratus clouds around Cook Inlet and
in the Copper River Basin will dissipate. This stratus is quite
widespread over the lower elevations of the Copper River Basin and
may present a challenge in completely clearing out. The main
impact clearing will have will be a sharp drop in temperatures
across the Basin without the cloud cover. Should the Copper River
Basin get the clearing tonight and tomorrow night, temperatures
around Glennallen will drop below zero, perhaps double-digits
below. Cook Inlet is in a similar situation, but there is a better
chance for this stratus to mostly dissipate today. As is the case
with these low stratus situations, there is no guarantee that it
will clear out. As with the Copper River Basin, overnight
temperatures the next two nights will be closely linked to the
loss of the low clouds.

On Wednesday afternoon into Thursday, an upper level low will dig
southward over Bristol Bay and bring in some moisture in the
southwest flow as well as some enhanced lift in association with
the low. This could bring some snow to parts of Southcentral,
though there is still a reasonable amount of uncertainty on
whether the moisture will mostly track up the western Susitna
Valley, or head farther to the east over the Kenai Peninsula and
Anchorage/Mat-Su. This does not look to be a big event, but it is
the next chance for any snow.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...

Light snow is developing along the Kuskokwim Delta coast this
morning, including Toksook Bay and Kipnuk, in response to a quick
moving upper level wave moving southwest of Nome. As the wave
continues to trek west of Nunivak Island, precipitation will taper
off and remain primarily offshore for the rest of today. In the
wake of the exiting wave, northerly flow will usher in colder air
across the Southwest mainland through the forecast period. Expect
daytime highs in the teens to the mid 20s and overnight lows in
the single digits to below zero.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...

The main feature will be an upper level disturbance moving south
of the Kamchatka Peninsula towards the western Aleutians and
phasing with a low currently situated south of Amchitka. With the
aid of colder air advection, high end northerly, gale force winds
will wrap around the western side of this system with seas
building to 10 to 15 feet late tonight and up to 20 feet by
Tuesday afternoon. The associated front will continue to progress
eastward, bringing a rain/snow mix along the Aleutian Chain
through the forecast period. Winds will lower to small craft with
decreasing waves by Tuesday evening as the low weakens and moves
southward, with a cool and showery pattern likely to persist in
the Aleutians, Pribilofs, and AKPEN through the middle of the
week.

&&

.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 dive 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.
