What forecasters said that day

The local office's own words before this small craft advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Anchorage, AK wrote its last area forecast discussion before this small craft advisory went out at Aug 13, 5:03 AM AKDT, 10 hours 33 minutes earlier.

Area forecast discussion, Aug 13, 5:03 AM AKDT, 10 hours 33 minutes before

Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
503 AM AKDT Fri Aug 13 2021

.ANALYSIS AND UPPER LEVELS...

The pattern remains amplified across the North Pacific. Upper
level troughing extends across the Alaskan mainland and eastern
Bering/Aleutians. Upper level ridging extends along the west coast
of Canada as well as the far western Bering. The jetstream
remains south of 50N through 145W, then extends northeastward into
Northwest Territory. A vertically stacked low currently near 46N
171E is weakening while moving northeastward.

Closer to the surface, radar imagery shows showers moving
northward across the Gulf of Alaska into Prince William Sound and
the areas in and around Cordova. Isolated showers are also slowly
moving across the Anchorage Bowl and Matanuska Valley.

&&

.MODEL DISCUSSION...

Guidance remains in good agreement with respect to the placement
and intensity of synoptic scale features at both the surface and
in the upper levels. Forecast confidence remains above average.

&&

.AVIATION...
PANC...Conditions will mainly be VFR during this TAF period.
Temporary IFR conditions are possible through 16z Friday as
isolated showers bring localized areas of low ceilings into the
area.

&&

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

The main weather feature over Southcentral Alaska is the large
upper level longwave trough extending out of the Interior and into
the eastern Bering Sea. This trough is keeping Southcentral under
moist southwest flow aloft and keeping showers across the region,
especially over higher elevations. Embedded in the southwest flow
are a series of shortwaves that have been bringing more organized
bands to the area. One such band moved across Anchorage and the
Matanuska Valley overnight and stretches from the Talkeetna
Mountains to the central Gulf of Alaska early this morning. There
is a surface low under this shortwave south of Cordova and that
low is enhancing the rainfall from eastern Prince William Sound
eastward. This low is moving eastward and the rain should taper
off later today as well.

The upper level trough has basically been in place all week and
has contributed greatly to the wet week we have had over the
region. This trough is finally starting to head eastward and
should reach the Alaska Range Friday night and then move to the
AlCan border Saturday evening. When the trough moves east of the
area, the showers will taper off in earnest.

&&

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

The longwave pattern features broad troughing from the Eastern
Bering to Mainland Alaska (right up to the Canadian Border). At
500 mb there is a closed low over the Beaufort Sea and a positive
tilt trough axis extending from Deadhorse to Bethel to Adak.
There are several vorticity lobes associated with the trough that
is bisecting the Brooks Range and the Bering. This pattern will
be conducive to intermittent showers. There is a transitory ridge
that will push over southwest Alaska Saturday morning and
afternoon. Then more shortwaves will get ejected from the
aforementioned closed low and move towards Kipnuk and beyond.
There is also an area of diffluence which would suggest another
round of unsettled weather...albeit showery in nature.

&&

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

The longwave pattern features broad troughing from the Eastern
Bering to Mainland Alaska (right up to the Canadian Border). At
500 mb there is a closed low south of Attu Island and a positive
tilt trough axis extending from Deadhorse to Bethel to Adak. There
are several vorticity lobes associated with the trough that is
bisecting the Bering. This pattern will be conducive to
intermittent showers. Friday and early Saturday the winds will
vary from light to small craft. Later Saturday there is the
possibility of Gale Force winds for the western Aleutians as a low
approaches. The current thinking is that these enhanced winds will
be short lived and will subside on Sunday.

&&

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

Forecast confidence is good. A low crosses the Northern Bering by
Tuesday. Gusty winds less than gale force with the low. High
pressure expands across the Bering after the low moves onshore. A
series of low track eastward to the South of the Aleutians through
Tuesday. Gusty winds less than gale force with the lows spread
over the Aleutians to the Southern Bering through Tuesday. Gusty
winds less than gale force around Kodiak Island with gale force
gap winds over the Barren Islands and Sitkinak through Monday,
diminishing. A low and front moves into the the Western Gulf
Tuesday. Gusty winds less than gale force with local areas of gale
force winds over the Southern Gulf Tuesday. Seas less than 10
feet across all areas.

&&

.LONG TERM FORECAST (Days 3 through 7: Sunday through
Thursday)...

Long-term guidance is in general agreement with the overall
synoptic pattern through the latter half of next week, including
high pressure over the gulf and low pressure over Alaska and the
Bering. Initially, an area of high pressure on Sunday is forecast
to push eastward across the gulf and out of the forecast area by
Monday. This is expected to be followed by the amplification of a
stronger North Pacific ridge into the gulf next week. Out west, a
current North Pacific low and its associated moisture will
continue eastward and into the Eastern Aleutians and Alaska
Peninsula with scattered showers through Monday.

More uncertainty develops next week with regard to the arrival of
several upper-level disturbances from the Bering. Models depict
an active period with said disturbances forecast to dig eastward
across the state. While timing and intensity of each disturbance
is less clear, the strengthening ridge of high pressure over the
gulf should help to steer each disturbance into Southcentral with
multiple opportunities for rain next week. The Canadian model is
somewhat of an outlier currently with a much stronger ridge in
place by midweek and forecast waves of low pressure lifting almost
due north across the state. Regardless, cooler conditions and
intermittent showers can be expected across Southwest with
continued rain chances across Southcentral through next week.
