Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
547 AM AKST Tue Nov 3 2020

.ANALYSIS AND UPPER LEVELS...

In the upper levels...a 500MB low continues to remain stationary
over Prince William Sound. This is at the center of a broad
longwave trough over Southcentral AK and the Gulf of Alaska, which
has a cold pool of air accompanying it. A ridge of high pressure
continues to exist on an axis extending from the Western Aleutians
northeast across the Bering into Southwest AK. A sharp trough
exists just north of the Bering Strait and is beginning to move
south. It is this trough that will set up Blizzard conditions in
Southwest AK later today and bring some strong cold air advection
and windy conditions to the Aleutians.

On the surface...The 500MB low in the upper levels is keeping cold
air in place on the surface. A surface high remains in place over
the mainland, with weak low pressure located in the Gulf of
Alaska. This high is associated with cold, dense air. The high
coupled with low pressure just off the coast is creating windy
conditions through gaps and passes. Out in the Bering, a surface
high exists and is centered over the Western Aleutians, with
ridges extending to the north and east. This is keeping the Bering
and Southwest AK quiet for now. The upper trough north of the
Bering Strait is reflected on as a surface low located in the
Strait extending to St. Lawrence Island. This trough has begun to
move south which will make for active weather later today.

&&

.MODEL DISCUSSION...

Models are in very good agreement in the short term. All of the
major models are capturing the upcoming blizzard event in
Southwest AK. They also appear to capture the trough currently in
Russia that will drop into our forecast area later this week. They
track its progression well through the short term. One area where
models consistently underperform are wind speeds through the
Eastern Aleutians with northerly wind events. This has been
compensated for with pattern recognition and we have a good handle
on upcoming winds for that area. Therefore, we have high
confidence in the forecast.

&&

.AVIATION...

PANC...VFR conditions will persist. Light north winds will
continue but gusts will slowly weaken.

&&

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

A weak surface low in the northern Gulf will continue to bring
occasional light snow showers to eastern portions of Prince
William Sound today, tapering off tonight as the low moves east.
Also tonight, a shortwave trough will rapidly move from Bristol
Bay into the North Pacific, with a brief period of snow expected
across the southern portions of Kodiak Island as it rolls through.

With outflow winds subsiding, we are setting up for a very chilly
night tonight with low single digits expected for the Anchorage
Bowl, single digits below zero across the Mat-Su Valley, and teens
and 20s below zero in the Copper River Basin.

Wednesday evening into early Thursday, a strong northerly jet
works into the area as an upper ridge builds across Western
Alaska. The orientation of this jet will help to again enhance
outflow winds, especially for Thompson Pass. We have hoisted a
High Wind Watch to account for this. While it does not look like
an overly impressive set-up, it definitely has potential. In
addition to Thompson Pass we should see some increasingly gusty
winds for Passage Canal, Resurrection Bay and Valdez during this
period.

On Thursday a frontal system moves in from the west, with light
snow changing to light rain across Kodiak Island early. Late
Thursday into Thursday night, chances for light snow increase for
the Kenai Peninsula, Anchorage and the Mat- Su Valley. There could
be a few inches of accumulation for the population centers by the
time the week is over.

&&

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

A strong shortwave trough travels southeast across the Kuskokwim
Delta towards Bristol Bay today. Behind the wave, gusty
northwesterly flow and cold air advection over warmer sea surfaces
sets the stage for blizzard conditions along Kuskokwim Delta
coast today and tonight. Additionally, expect strong winds and
periods of reduced visibility.

A low pressure system currently over Russia enters the Western
Bering Wednesday morning. The associated front reaches the Southwest
Coast by Thursday afternoon, bringing a round of showers to the
region on Thursday. Warmer air will be out ahead of the front,
allowing the coastal areas to stay warm enough for rain, and keep
the snow showers further inland. Persistent southwesterly flow
with this front could produce significant onshore flow, leading to
flooding concerns for the Kuskokwim Bay and possibly Bristol Bay
Thursday afternoon. Storm track and ETSS guidance will continue to
be monitored over the next couple days as the system approaches.

&&

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

A high amplitude trough currently set up over Russia is creating
a short-lived period of ridging over the Central Bering today. By
Wednesday, the front pushes into the Western Bering, weakening as
it travels east. Storm force winds with periods of hurricane
force gusts dominate the Western and Central Bering through
Thursday morning. As the front approaches the Southwest coast
Thursday afternoon, winds diminish to widespread gales. A
widespread band of precipitation and warmer air also precedes the
front, thus, light to moderate rain showers are expected along the
Aleutian Chain Wednesday into Thursday.

&&

.MARINE (Days 3 through 5/Thursday through Saturday)...

A strong Kamchatka low will push a front across the Bering
Thursday. Southwesterly storm force winds and seas up to 30 feet
are expected across the Bering early Thursday before winds
diminish to gales late Thursday. As this Kamchatka low weakens
Friday, winds will diminish to small craft levels. Another low
arrives over the western Aleutians Saturday bringing the
potential for gale force winds.

For the Gulf, gusty northerly outflow winds are expected early
Thursday especially over the Barren Islands. Winds will shift
to southwesterly Friday for the western Gulf especially through
Shelikof Strait as a ridge strengthens over the Gulf for the
weekend. Southerly gale force winds may return to the western
Gulf waters by Saturday as a North Pacific low lifts northward
near Kodiak Island.

&&

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

Two key features that have been consistent for the long term
forecast include an upper level low over the Kamchatka Peninsula
and a strong upper level ridge maintaining its hold over the Gulf
of Alaska. Active weather is expected for southern Alaska for the
start of the weekend as a North Pacific low lifts northward and
attempts to suppress the persistent Gulf ridge to the south. As
this low moves into the Bristol Bay region early Saturday, a
strong pressure gradient between the incoming low and the
persistent high will generate gusty southerly winds across the
western Gulf waters and Kodiak Island. Additionally, there is
potential for a wintry mix of precipitation for interior Bristol
Bay and the Middle Kuskokwim Valley as this low lifts northward.
Depending on the track of this low, wintry precipitation is also
possible for Southcentral Saturday and Sunday. Model solutions
continue to change with regard to where this low tracks, so
confidence remains low at this time. By Sunday, an upper level
low builds in across much of the state, ultimately displacing the
persistent upper level ridge to the south. Farther west, a strong
Kamchatka low develops late Saturday and pushes a front across
the Bering Sunday. Right now, an active weather pattern looks to
persist through the start of the next work week.
