Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
500 PM AKDT Mon Oct 25 2021

.ANALYSIS AND UPPER LEVELS...
The 500 mb pattern has an upper level low in the Chukchi Sea with
another, weaker low, over the Northern Gulf coast this afternoon.
This is keeping southern mainland Alaska under light upper level
flow under the trough connecting these lows. A surface low is just
a little west of Middleton Island and pushing some rain and snow
onshore along the north Gulf coast. The larger and stronger
surface low is south of Kodiak Island and is the source of the
gusty north-to-northwest winds along the Alaska Peninsula and
eastern Aleutians. The 250 mb jet stream is running west-to-east
to the south of this low and can be seen well on satellite.

&&

.MODEL DISCUSSION...
Models are in overall good synoptic agreement through the week.
There is still a bit of uncertainty as to the way a low in the
northeastern Bering Sea on Tuesday night will progress
southeastward, but this is likely to be of little overall
significance. The main model item is the way the ridge over the
west coast of North America amplifies in conjunction with a low
moving just south of the Aleutians late this week. This overall
pattern is a rather high-confidence one in that the models are
likely resolving it correctly. However, there are important
details that differ between the models that will impact the
sensible weather we will be looking at as this system develops.
More on this in the long term section of the discussion.

&&

.AVIATION...
PANC...VFR conditions and light winds will persist.

&&

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

Generally quiet conditions will prevail across Southcentral for
the beginning of the short term period. Light showers occurring
in Prince William Sound, along the eastern Kenai Peninsula, and
eastern Kodiak Island will persist through tonight and then
gradually clear out in association with a broad area of low
pressure lingering in the Gulf. At inland locations, little
precipitation is expected with only weak shortwaves cycling
through the region. A stronger low pressure system south of Kodiak
Island this evening will track across the southern edge of the
Gulf through tomorrow, inducing a pressure gradient that will
drive gusty gap winds out of the typical areas along the coast. In
concert with the North Pacific low, a ridge over the eastern
Bering and Southwest Alaska will draw colder Arctic air across the
Aleutian and Alaska Ranges tomorrow and Wednesday. Cold air
advection will help to bolster gap winds and lead to a cooling
trend across Southcentral over the next several days, with highs
in the low-to-mid 30s in the inland lower elevations by Thursday
and lows in the 20s in the Anchorage Bowl and along coastal
locations Wednesday night. The next round of active weather will
arrive with a front pushing from the North Pacific over Kodiak
Island Wednesday night. While timing is still somewhat uncertain,
gusty winds and rain are expected to push toward the north Gulf
coast through Thursday.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 through 3...Tonight
through Thu afternoon)...

Mostly dry conditions are expected across much of Southwest
through Tuesday afternoon. An upper level shortwave trough is
expected to move from the Kuskokwim Delta Coast this evening to
the western Alaska Range south to Kodiak Island by Tuesday night.
Only areas along the immediate Kuskokwim Delta Coast are expected
to see any precipitation as this shortwave trough passes through.
Expect flurries/light snow showers for Nunivak Island and areas
such as Hooper Bay, Chevak, Toksook Bay this evening through the
overnight hours with little to no accumulation. As this shortwave
trough moves over the Kuskokwim/Kilbuck Mountains Tuesday morning,
expect breezy conditions for much of the day Tuesday especially
for Iliamna and the Kamishak Gap area. This will be the result of
cold air advection combined with the upper level support Tuesday
causing the expected breezy conditions. Winds may gusts upwards of
30 mph around Iliamna. Also, expect gusts up to 50 kts out of the
bays and passes south of the Alaska Peninsula tonight and Tuesday.

Next, onto the bigger story, a low pressure system is expected to
move across the northern Bering Sea Tuesday reaching the Southwest
Coast by Tuesday night. This low's associated front is then
expected to affect much of Southwest, especially coastal locations
through Wednesday and into Thursday. Right now it appears to be
a widespread light snowfall with any banding not expected to
remain in one place at this time. However, uncertainty is still
the name of the game with this system as some guidance hints at a
a band setting up shop somewhere between Dillingham to Koliganek
and New Stuyahok south and east to near Iliamna and near or north
of King Salmon. The other is also true that this band sets up
right over Dillingham or King Salmon. As of now, went with a
general 1 to as much as 4 inches in any one location for this
event, though, if a band remains in place somewhere for any
prolonged period of time in excess of 6 inches could be possible.
Therefore, stay tuned for the latest forecast updates as we
continue to hone in on this system. It also looks like it will be
cold enough to support all snow with any mixing issues either
right on the immediate coastline or even a little further off the
coast over the water.

&&

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

Northwesterly flow continues across the east-central and eastern
Bering through this evening and into the overnight hours. This
includes areas such as the Eastern Aleutians and the Pribilofs. An
upper level shortwave is also moving southward embedded in the
upper level flow that is bringing snow showers and a colder air
mass as well to the aforementioned areas this evening through the
overnight hours.

Next, a tightly compact system is expected to move across the
northern and eastern Bering Tuesday through Wednesday with high
end gale force winds and storm force gusts for these areas. The
corridor of strongest winds are expected on the southwest to west
side of the system Tuesday evening into Wednesday morning. There
may also be an area of storm force sustained winds but there was
not enough confidence to place into the forecast this package.
Stay tuned in case this is updated in subsequent updates. This
system is expected to bring a rain/snow mix to the Pribilofs
Tuesday into Wednesday with the best chance for snow Wednesday
when the colder air moves in on the back side.

Another low pressure system is expected to move across the Western
and Central Aleutians Wednesday afternoon through Thursday evening
with rain and high end gale force winds. The storm force winds are
currently expected to remain south of the coastal waters marine
area.

&&

.MARINE (Days 3 through 5: Thursday through Saturday)...
The main storm of concern for late this week will be one that
tracks jut south of the Aleutians and brings Gale and probably
Storms force winds to the Aleutians Thursday into Friday. This
low will then elongate along a north-to-south line from Kodiak
Island Southward which will likely bring storm force winds across
the Gulf of Alaska Friday night into Saturday with Gales and
possibly a few storms over Bristol Bay and the Alaska Peninsula at
that time. This overall pattern is one that is likely to develop
as described so the main uncertainty will be the details in where
and when the strongest winds and highest seas will be.

&&

.LONG TERM FORECAST (Days 4 through 7: Friday through Monday)...
Friday will be a day where the pattern starts to transition into
an active and stormy one for the forecast area. Southern Mainland
Alaska will start off under a cold upper level trough with a few
shortwaves overhead and then transition as a major storm which
will have just moves south of the Aleutians elongates over Kodiak
Island and southward. This will usher in much warmer and wetter
air to southcentral Alaska by Friday night (during the day Friday
for Kodiak). Strong winds will encompass the entire Gulf of
Alaska area and push inland some. The main impacts will be the
potential for heavy and prolonged rainfall from anywhere from
Kodiak eastward to Cordova (including the Seward area) in this
atmospheric river event. There remains a bit of uncertainty as to
where the heaviest rain will occur and for how long. This is one
of the main forecast questions that will need to be addressed
through the remainder of the week. High winds are possible for
Turnagain Arm depending on the exact track of the low.

Southwest Alaska, Alaska Peninsula, and the eastern Bering Sea
will be in the colder, drier northwest flow and see windy
conditions for Friday into Sunday. By Saturday night, the next
strong low will move to the western Aleutians and then encompass
most of the Bering Sea region for Sunday into Monday.
