Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
429 AM AKDT Fri Oct 22 2021

.ANALYSIS AND UPPER LEVELS...

Lows in the Bering Sea and the Gulf of Alaska continue to
influence weather in the Aleutians and Southern Alaska. In the
Bering Sea, a strong low lies in the left exit region of a 170 kt
jet streak. On the backside of the low, a tight pressure gradient
and strong cold air advection are producing high winds in the
Eastern Aleutians. Winds in Dutch Harbor have reached 61 mph,
with gusts up to 83 mph. Near Nikolski, sustained winds up to 87
mph and gusts over 115 mph have been observed. Scatterometer data
observed near midnight reveals a broad swath of hurricane-force
winds in the seas around the Eastern Aleutians. The low in the
Bering is also pushing a front into the Southwest. While the
radars in Bethel and King Salmon are detecting hydrometeors over
the Southwest, dry air at the surface is limiting precipitation to
virga.

A low moving up the Alaska Panhandle is increasing cloud cover
over the North Gulf coast and the Copper River Basin, though rain
has not yet reached the area. Moist conditions at the surface and
mostly clear skies between the two lows have produced areas of fog
across the Cook Inlet region. Visibilities have dropped to a
quarter mile in the Anchorage Bowl, with freezing fog present
where temperatures are below freezing.

&&

.MODEL DISCUSSION...

Models continue to be in good synoptic agreement in the short-term.
Minor disagreements arise as the low in the Bering crosses into
the North Pacific and interacts with the low currently in the
Gulf. The GFS and Canadian solutions maintain a tighter pressure
gradient associated with a meso-low along the Northern Gulf,
producing a stronger, broader, and longer persisting gale-force
barrier jet than the NAM on Saturday. For Sunday, models differ on
the track and winds for a low moving near the Aleutians. Most
solutions have the low center tracking south of the Aleutians
with high- end gales possible for the coastal waters. The
Canadian seems to be an outlier as it brings the low center
further north into the Aleutians. It also keeps the low stronger,
with a broad swath of storm-force winds. Overall, forecast
confidence is average.

&&

.AVIATION...

PANC...Dense fog will keep visibilities near a quarter mile into
the morning, with freezing fog possible as temperatures continue
to drop. VFR conditions and light winds are expected after
sunrise, though the timing of fog dissipation remains uncertain.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2: Today
through Saturday Night)...

A pair of strong lows are both separately impacting portions of
Southcentral this morning. The strong Bering low's leading front
is over Kodiak Island, causing breezy conditions and mountain snow
there. Meanwhile the northwestern edge of a second low near the
southern Panhandle is quickly moving westward across the Copper
River Basin and the north Gulf coast, spreading rain across Prince
William Sound. In between these two features, a rapidly shrinking
area of clear skies allowed fog to develop in a narrow band along
the Glenn Highway through Anchorage and extending down to a small
area of the Sterling Highway just east of Sterling. The fog is
dense across much of Anchorage, and will persist for the next
couple hours until the clouds now moving into the Matanuska Valley
make it to Anchorage and disrupt the fog development process.

Precipitation from this second Gulf low will struggle to make it
much further than the Kenai and Chugach Mountains. However, rain
and snow are likely to impact the Seward Highway through Portage
Valley and Turnagain Pass again today, making for slick
conditions. The precipitation through that area will be nearly
continuous through Saturday night, but is not expected to be
particularly heavy. By Saturday night an upper level disturbance
will drag some of the moisture further north, making for some
light snow across the northern and western Copper River Basin.

Except across the Gulf, the winds will be relatively light through
the gaps through Saturday night. A brief period of storm force
easterly winds is likely to develop late tonight into Saturday
across the northern Gulf, but will quickly diminish by Saturday
evening.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2: Today through
Saturday night)...

A strong low near the AKPEN is producing gusty winds for much of
area with snow mainly over the Kilbuck Mountains and the western
Alaskan Range while downsloping will keep most populated areas dry
with just cloud cover today. As the low moves into the Gulf this
evening a few rain showers will affect parts of Bristol Bay.
Showers will continue to be possible through Saturday night as
the deformation zone of the low pressure affects parts of Bristol
Bay. Colder air will move in from the north across the Kuskokwim
Delta Saturday night with a few snow showers possible.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2: Today through
Saturday night)...

A hurricane force low continues to move across the AKPEN near
Cold Bay this morning. It will continue to produce high winds
across the eastern Aleutians today with winds gradually decreasing
through this evening as the low moves towards the Gulf this
evening. A high wind warning continues for the eastern Aleutians
through this afternoon. Otherwise as the low moves east Friday
night high end gales will continue through Saturday across the
eastern Aleutians and AKPEN through Saturday night. Farther west
a ridge of high pressure will affect the western Bering and
western Aleutians today through Saturday night with light winds
and quiet weather.

&&

.MARINE (Days 3 through 5/Sunday through Tuesday)...

Bering Sea - Forecast confidence starts fair, but decreases
through Tuesday. Lingering gusty winds over the Eastern Bering and
Bristol Bay on the rear flank of a Gulf Low diminishes Monday. A
well developed low South of the Aleutians moves into the North
Pacific for Late Sunday. Gale force winds over the Western and
Central Aleutians moves into the Pacific on Sunday. Seas to 25
feet over the Aleutians Sunday and Monday, subsiding. A couple of
troughs moves across the Bering through Tuesday, bringing gusty
winds to the Northern Bering for Monday and Tuesday, and the
Western Bering for Tuesday.

Gulf of Alaska - Forecast confidence starts fair, but decreases
through Tuesday. A weakening low east of Kodiak Island remains
nearly stationary through Tuesday. Gale force gap winds extend
into the Western Gulf, diminishing Sunday, but re-intensify Monday
and Tuesday. Gale force gap winds spread over the Barren Islands
late Monday into Tuesday. as the low drifts into the North Pacific
for Tuesday.

&&

.LONG TERM FORECAST (Days 4 through 7/Sunday through Wednesday)...

The key features in the long term include a broad upper level
trough over the Bering with a vertically stacked and departing low
over the Gulf. A weak upper level ridge attempts to nose in over
the Alaska Yukon border Sunday. Meanwhile, a deepening low arrives
over the western Aleutians and traverses the Chain Monday and
tracks eastward. As things progress through the start of the next
workweek, the trough deepens and extends farther south into the
Gulf of Alaska, allowing the Bering low to move into the Gulf by
Tuesday. As a result, widespread precipitation and gusty winds are
likely across the Gulf and northern Gulf coast on Tuesday.
Meanwhile over the Bering, a surge of colder, northerly flow looks
to arrive for Tuesday and Wednesday.
