What forecasters said that day

The local office's own words before this gale warning 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 gale warning went out at Aug 12, 12:34 PM AKDT, 3 hours 27 minutes earlier.

Area forecast discussion, Aug 12, 12:34 PM AKDT, 3 hours 27 minutes before
Southcentral and Southwest Alaska Forecast Discussion...CORRECTED
National Weather Service Anchorage AK
1234 PM AKDT Sat Aug 12 2017

.ANALYSIS AND UPPER LEVELS...
Well the weather "show" is starting to get underway. The
vertically stacked low over the northwest Gulf continues to advect
plenty of moisture into southern AK with broad southerly flow. It
is very slowing tracking off to the northeast this morning and
will continue that track through the day. Widespread showers are
evident on the Middleton and Kenai radars, with the most
consistent precipitation along the north Gulf coast. This low is
also making for some stronger easterly winds along the coast as it
pushes mass up against the terrain.

The second, stronger low is diving south into Western AK with the
help of a 105 kt jet. The associated cold front is just starting
to move onshore near the Kuskokwim Delta. The rain shield
associated with it is rather impressive, stretching from the
Alaska Peninsula up through the Yukon Valley. Behind the low, an
unstable airmass is apparent with all the open cell cumulus
clouds tracking towards the Pribilof Islands from the Bering
Strait. This is bringing some gusting northerly winds to this
region for the first time in several weeks. Light flow over the
Central and Western Aleutians continues to allow widespread marine
stratus and patchy fog to plague these areas.

&&

.MODEL DISCUSSION...

Models are in great agreement with the timing of the front as it
sweeps across the AOR today. Minor differences exist in the exact
placement of the heaviest QPF over the weekend due to small
differences in the handling of weak waves aloft. Overall though,
confidence is high that the front and its associated rain
currently over the west coast will move into Southcentral by
tonight.

Forecast confidence quickly drops off Monday night into Tuesday
as models are having difficulty in the handling of the strength
and position of a low moving into the Gulf. The NAM is the
southern outlier keeping the feature over the southern Gulf while
the EC brings a stronger low and associated rain to the northern
Gulf coast. A more middle ground GFS solution was used in the
handling of this low for the morning forecast package, however
only minor edits were made to Tuesday's forecast due to model
discrepancies.

&&

.AVIATION...
PANC...The rain will vary in intensity as it moves through in
pulses today. The result will be VFR ceilings which could dip to
MVFR at just about any time, especially in heavier showers. Winds
this evening will be quite tricky. As the front approaches, we
should see an increase in flow from the southeast. Then as the
front starts to move through, the winds will become a bit more
gusty and start to bend to a more south to southwest direction.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
Unsettled weather continues across Southcentral Alaska. A large
cold upper low and associated trough over Bristol Bay this
morning moves over the Kenai Peninsula tonight. The upper low
weakens as it moves into the southeast Copper River Basin Sunday
evening. Cooling temperatures aloft with this feature will
increase the instability across much of Southcentral with isolated
thunderstorms expected over the Susitna Valley and Copper River
Basin today/evening and the Copper River on Sunday. Thunderstorms
are also possible over the warmer waters of the northern Gulf this
afternoon into Sunday morning. Widespread showers/rain moderate
to heavy at times across Southcentral today/tonight will slowly
diminish from the West overnight and into Sunday. Westerly to
southwesterly gales/gale- force gusts are expected with cold
advection over the Western Gulf this afternoon through Sunday
morning.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
Widespread precipitation is already on the radar at Bethel. The
surface low is just north of Bethel. As time elapses...anticipate
further deepening and the upper level shortwave will become
negatively tilted. Expect widespread showers with high elevation
snow. The nose of the jet will dive into the AK Peninsula with
the core going directly over Katmai National Park tonight. This
will prove to be a fast moving system although the tight pressure
gradient and associated gusty winds will remain over the AKPEN
for the forecast period.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
The latest ASCAT pass depicts a clear wind shift over the Bering
with the cold front near the Pribilof Islands. Expect the rapidly
moving front to continue to surge south and then the supporting
upper low will curve inland later today. The tail of the front
will bring showers to the Aleutians with the highest storm total
amounts east of Cold Bay. Aloft a vigorous jet core will push
along the eastern Bering and into Bristol Bay resulting in gusty
winds. All the while...a secondary disturbance south of the
Aleutian Chain will propagate eastward with the northern edge of
the precipitation shield taking a glancing blow at the
archipelago.

&&

.LONG TERM FORECAST (Days 3 through 7)...
One important change in the models early next week has been a
trend towards a more progressive upper level trough over the
mainland late Sunday. As a result there is now general consensus
that weak high pressure will develop over the south mainland Mon-
Tue between the departing low and the next low diving southward
into the Eastern Bering. This high pressure should bring a brief
break in the active weather pattern to much of Southcentral early
next week, however there is very good agreement that a series of
arctic troughs will move through the Mainland and Eastern Bering
into late next week. There are some timing/intensity issues in
the models from these trough, so forecast confidence is low on the
exact details of the long term forecast. Forecast confidence is
however good with the overall trend of continued cool, wet, and
fall-like conditions.
