Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
535 AM AKDT Sun Oct 17 2021

.ANALYSIS AND UPPER LEVELS...

An upper trough combined with multiple shortwaves wrapped into an
upper low over the eastern Bering brings steady rain and gusty
winds over much of the Aleutians, Southwest Coast, Pribilof
Islands and the western Gulf this morning. A weak shortwave ahead
of the trough has ushered increased clouds and light rain over
the southern Cook Inlet and around southern Kenai Peninsula. An
upper ridge extends from the North Pacific through the State to
the Bering Sea, causing a subtle break in showers for areas along
the ridge axis.

&&

.MODEL DISCUSSION...

Computer models are in good agreement with the large scale
patterns for both the short and long term. A series of combined
former Northwest Pacific tropical systems and North Pacific lows
will create prolonged active weather for both Southwest and
Southcentral in the coming days. Whether these expected systems
stay on-track or not as they approach the forecast area, there is
at least adequate agreement on the timing of these isolated
episodes especially through the short term. Overall, the forecast
confidence is high.

&&

.AVIATION...

PANC...VFR conditions will persist. At near 2000 ft, wind shear
is expected to pick up to 30 kt this morning for a few hours.
Essentially, gentle to moderate northerly winds near surface and
broken to overcast cloud coverage will potentially last through
tonight.

&&

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

The strong front associated with the Bering Sea low is upon Kodiak
Island early this morning. This is bringing strong winds and heavy
rain to the Island with rainfall spreading to the north Gulf coast
as well. As was discussed yesterday, the main low in the Bering
Sea is a complex low with a new center developing along the front
near Kodiak Island. What is interesting about the way this low is
developing is that this low near Kodiak will move eastward as
another low center farther west in the Bering moves toward Kodiak
Island tonight. This will cause the front to elongate across the
Gulf, but it will remain quite strong with Gale to Storm force
winds associated with it. This will also keep the front from
pushing inland and therefore keep precipitation mainly relegated
to the coast and coastal mountains. Sea level locations will be
all rain but areas above 1000 ft will see snowfall with this
front.

Inland areas such as Anchorage northward and the Copper River
Basin will see the precipitation mostly downslope out and with the
cross-barrier flow. The flow aloft will mainly have a east-to-
northeast tilt, as opposed to a southeasterly direction. This is a
drier pattern as well.

The front will remain nearly stationary from the eastern Gulf to
Prince William Sound through Tuesday and maintain gale force
winds with the potential for some periods of storm force winds.
This will really crank up the seas with widespread 20+ foot seas
developing and then persisting for a few days.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 through 2: Today
through Monday)...

As a low in the Bering moves into the Pacific, precipitation over
the Southwest will slowly taper off through Sunday evening.
Winter Weather Advisories remain in effect for parts of the
Kuskokwim Delta and Bristol Bay until early Sunday morning, though
additional snow accumulations are expected to be light. Strong
winds may resuspend snow on the ground, potentially affecting
visibilities even after snowfall ends. However, the likelihood of
blowing snow diminishes by the afternoon as temperatures increase.
Warming temperatures will also cause precipitation to transition
from snow to rain or mix in areas over and north of Dillingham.

A ridge builds in Sunday evening as the low progresses southward.
Winds weaken and skies begin to clear, allowing temperatures to
drop into the 20s Sunday night into Monday morning. Skies remain
relatively clear through Monday, though clouds begin to build in
from the west as another warm front approaches. Temperatures will
initially be cold as the front pushes through the Southwest Monday
night, but southerly flow along the front will quickly raise
temperatures above freezing. Therefore, precipitation is currently
expected to begin as snow but persist primarily as mix or rain as
the front progresses inland.

&&

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

A broad low in the Bering will continue to impact the Aleutians
through Monday morning. Cold air advection along the back side of
the low continues to drive strong winds through the Central
Aleutians through Sunday morning. Over the Eastern Aleutians and
AKPEN, light rain lingers through Sunday evening and winds become
northerly as the low moves out of the area. Gusty winds are
expected late Sunday night into Monday morning as winds funnel
through gaps and passes.

A ridge builds in behind the departing low, bringing weaker winds,
clearer skies, and a break from the rain. However, unsettled
weather quickly resumes as a low near the Kamchatka Peninsula
pushes a warm front across the Aleutian Chain beginning Sunday
night. Light rain and winds below gale force are expected with
this weaker warm front. A cold front follows on the heels of the
warm front, bringing gale force winds and ocean-effect rain
showers beginning Monday morning.

&&

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

Bering/Aleutians

Forecast confidence is above average for Tuesday and Wednesday as
guidance shows similar solutions with respect to the placement and
intensity of synoptic scale features. Forecast confidence becomes
low on Thursday as guidance shows significant differences in
solutions with the placement and intensity of a low pressure
system in the western and central Bering/Aleutians.

Gulf of Alaska

Forecast confidence remains above average across the Gulf of
Alaska during the days 3-5 period as guidance shows similar
solutions in the placement and intensity of synoptic scale
features. Minor differences exist between guidance with respect to
the development and decay of the barrier jet expected in the
northern Gulf on Tuesday and Wednesday. There is a high confidence
gale force winds will occur in the northern Gulf during that
time.

&&

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

A cloudy, wet and cool pattern is expected across Southcentral
during the extended period. A positively-tilted upper level trough
is expected to extend from the northern Bering Sea into the
central Gulf of Alaska. The pattern will also be wet in
Southcentral because the trough-axis will remain southwest of the
Kenai Peninsula which will allow for an predominant onshore flow
pattern while easterly upper level waves move across the area. For
now, there is lower confidence with respect to precipitation type,
though snow becomes more likely as elevation increases. The
Bering/Aleutians will be in a persistent cloudy and cool pattern
with showers as broad upper level troughing will remain in place
across the area.
