Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
601 PM AKDT Tue Sep 14 2021

.ANALYSIS AND UPPER LEVELS...
The stagnant upper-level low continues to sit over southwest
Alaska as a number of shortwaves rotate around its periphery. The
most easterly of these waves is just now (14/21Z) coming up the
Kenai Peninsula and is spreading showers from there out east
through Prince William Sound ahead of its associated boundary. The
second shortwave is currently over the Bering Sea and has
increased winds across the marine areas and areas further inland.
These two shortwaves will be the major players for the rest of
today and tomorrow.

The closed low situated farther west over the sea will be the
next big player come Thursday and through the weekend as it ushers
in an open trough and a wide swath of moisture and increased
winds aloft for colder and wetter conditions. Satellite is showing
a healthy precipitable water layer to its south at this time.

&&

.MODEL DISCUSSION...
Models are in fairly good agreement on the details as the first of
the shortwaves rotate around the low still anchored over
southwest Alaska. Some differentiation exists in the models as
the second shortwave drops south and east around the low, which
has posed some precipitation timing and wind strength
discrepancies; this means we have lowered forecast confidence
with these finer details. Of course, by Thursday, models struggle
with how fast to develop the incoming upper-low center as it gets
swept east and develops into more of an open wave. Increased
winds and a wide swath of moisture will be associated with it, but
whether we are looking at just cooler temps or if a heightened
precip events is on hand remains to be seen.

&&

.AVIATION...
PANC...VFR conditions under FEW and SCT ceilings this afternoon.
Increased shower activity will commence in the next few hours with
a passing shortwave aloft and increased instability. Showers will
certainly increase by 15/09Z when more consistent showers begin.
This period of showers will be accompanied by increased southeast
winds with gusts up to 20kts.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3:
Tuesday afternoon through Fri)...

A detached upper low extending east from main low over the Y-K
delta is moving southwest to northeast over Southcentral this
evening. Showers are likely from the Kenai Peninsula north to the
Susitna Valley. Instability and onshore flow over the northern
Gulf will also keep showers along the coast through the night. As
this wave departs the main upper low will move east, continuing
rain through the morning hours for most of the region, with the
exception of the Copper River Basin. By Wednesday afternoon focus
shifts to a broad upper low being stretched east by a strong zonal
jet centered near the 50th parallel. The front from this system
will begin to impact Kodiak Island midday on Wednesday, bringing
heavy rain and 30 to 40 mph winds through the afternoon and
evening hours.

Uncertainty remains moderate for this system, with most model
guidance detaching the front from the main low center near Kodiak
Island. Overall the system looks less impressive than past
iterations, but gale force winds remain likely along the Gulf
Coast and through southern Cook Inlet. Most of the uncertainty is
in regards to whether a low will form along the front farther
north in the Gulf. Should this happen, locally higher winds are
likely. For inland areas, downsloping remains likely for the
population centers with heavy rain along the coast through Friday
morning. With strong southeasterly winds, rain totals for Seward
and Whittier are expected to be 1.75 and 3.8 inches over 48 hours
respectively. With the southeasterly flow, Cordova and Valdez
should be spared from heavy rain. On Friday the low will push
farther to the east, which should enhance northerly outflow winds
and allow for a general drying and clearing trend for the start
of the weekend.

&&

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

A wet pattern and gusty winds will continue into at least
Wednesday morning as a result of a slow moving trough wrapped to a
low over the Yukon Delta. The composure of the low is still intact
until it begins to lose energy overnight tonight, meanwhile a
considerable amount of rain continues to sweep eastward across the
Alaska Range into Wednesday morning. Satellite and rain
observations indicated steady light to moderate rain over much of
the lower Kuskokwim Valley and most of Kuskokwim Delta this
afternoon. West of this trough lies a developing upper ridge that
would build across Southwest into Thursday night, leading to a
nice break from showers. Between Thursday night and Friday
morning, an elongated Arctic trough accompanied by cold air
advection will enter the Southwest Coast which could bring our
first mixed rain/snow especially along the mountain tops by
Friday. At this moment, it's uncertain whether the broad area of
cold air advection (from -6C to -8C) will stay along the northern
portion of Southwest or extend southward into Bristol Bay between
Friday and Friday night. This latter pattern will certainly
require new updates in the coming days, stay tuned!

&&

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

Gales, strong gusty winds along the gaps and passes, and rain will
accompany the two separate lows moving across the Bering/Aleutians
through the next couple days. The first low over the western
Aleutians is expected to move toward Bristol Bay through Thursday
while a second low near Komandor Basin drives eastward toward
Shemya between Wednesday and Wednesday night. The latter system
will certainly absorb energy from the first low as it catches up
to the first low, leading to reinforced gales and strong winds
over the Aleutian Chain and the central Bering including Pribilof
Islands. This same system will generate hazardous seas up to 18 ft
between Wednesday morning and Wednesday afternoon.

A surface ridge building across the Bering starting Thursday night
could usher increased low clouds/stratus followed by a broad frontal
system from the Northwest Pacific on Friday morning.The front would
bring another series of rain and potential for strong gusty winds
over the Bering/Aleutian Chain on Friday and Friday night.

&&

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

Bering/Aleutians... A tightened pressure gradient lingering
across the Eastern Aleutians and Alaska Peninsula on Friday will
maintain potential for northwesterly winds below gale force,
especially for areas prone to gap winds. Winds then diminish as
high pressure ridging overspreads the Bering and much of the
Aleutians early Saturday. A second low will begin to move over the
Western and Central Aleutians throughout the day on Saturday and
eventually across the entire Aleutian Chain by Sunday. Downstream
south to southeast winds with potential for gale force gusts will
exist ahead of the eastward moving low. Behind the low, northwest
winds, potentially to gale force, may impact the Western Aleutians
on Sunday.

Gulf of Alaska... A broad low over the Gulf of Alaska on Friday
will begin to breakdown and shift southeastward into Saturday.
Elevated coastal winds with gusts to gale force located from the
Shelikof Strait up into Prince William South will also weaken and
move offshore of the coast in response to departing low pressure
to the southeast. High pressure then builds into the Gulf late
Saturday and Sunday with quieter conditions.

&&

.LONG TERM FORECAST (Days 4 through 7/Saturday through Tuesday)...

An unsettled weather pattern will continue into the weekend and
early next week. Across the Gulf low pressure is expected to
weaken late Saturday with calmer conditions setting in temporarily
through the first half of Sunday. Southcentral may even
experience some sun before the next front brings increasing clouds
and rain chances on Tuesday. However, with clearer skies and
calmer winds will come colder overnight lows as well. Some parts
of Southcentral are likely to see near-freezing or freezing
temperatures during the early morning hours this weekend as a
result.

The main feature driving the weather pattern in the long term
will be a strengthening area of low pressure that will be making
its way across the Aleutians over the latter half of the weekend
into early next week. Rain and elevated winds are expected both
ahead and behind the low as an occluded front precedes the low's
arrival. Gales will be possible across the Bering, the Aleutians
and portions of the Gulf as the low and front continue eastward.
While exact timing of the front is a bit less certain, models are
in general agreement that this front will track across the
Aleutians and into the Alaska Peninsula Saturday into Sunday, with
rain moving into Southcentral as early as Monday.
