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 Jan 30, 4:23 PM AKST, 11 hours 37 minutes earlier.

Area forecast discussion, Jan 30, 4:23 PM AKST, 11 hours 37 minutes before

Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
423 PM AKST Mon Jan 30 2017

.ANALYSIS AND UPPER LEVELS...
There is a large upper level trough over the Bering Sea and
Aleutians moving eastward. An associated front is pushing through
southwest Alaska and into Southcentral, bringing winds and
precipitation with it. There is an upper level ridge over eastern
Alaska with the axis near the Canadian border. This ridge is
slowly moving east. An upper level low south of the Kamchatka
Peninsula is moving toward the northeast. This is beginning to
develop a ridge ahead of it (to the east), and behind the
Bering/Aleutian low.

&&

.MODEL DISCUSSION...
The numerical models are in fairly good agreement through the
short term portion of the forecast (Wednesday afternoon). There
are some important differences in how they handle the
precipitation for inland areas, mainly in how strong downslope
drying may be, and how long it will last.

&&

.AVIATION...
PANC...Gusty southerly to southeasterly winds are expected through
most of tonight, before diminishing Tuesday morning. VFR
conditions are likely to persist through tonight. Conditions could
lower to MVFR at times on Tuesday from late morning through the
afternoon in snow, but confidence is not real high and thus the
TAF was left at VFR.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
South to east winds will continue to increase across much of the
region tonight as a strong frontal system pushes into the Gulf
region from the west. With the parent low tracking northward into
the northern Bering, the front has started to elongate and stall
over the western Gulf. The front will remain stalled over the
western Gulf through Tuesday, but continue to weaken. With a
shallow layer of cold air in place and unstable conditions right
above this, expect stronger winds to mix down to the surface in
many places, from the Kenai Peninsula to Anchorage and the Mat
Valley. East to southeast gap winds will also be in full force,
with the Turnagain Arm wind expected to bend into south to west
Anchorage later this afternoon through tonight.

With such strong low level southeast flow, the lee of the Kenai
and Chugach mountains will initially experience downslope drying.
However, as the surface front weakens tonight through Tuesday,
downsloping winds will weaken and snow will likely move into the
population centers. Despite the deep southerly flow out ahead of
the front, the air mass will remain cold enough for snow in most
locations, with the exceptions being Kodiak Island and the
immediate Gulf coast.

Forecast confidence has increased in a frontal wave developing
into a closed low over the western Gulf on Tuesday, with lower
confidence in the exact track of this feature. This is critical
for determining where the deformation band will setup, and how
long it will persist over a specific area. With the models in
slightly better agreement with the placement of this feature, we
are expecting the deformation band to set up over the Cook inlet
region and extend Northward into the Western Susitna Valley. Areas
that have the potential to see significant snowfall along a
deformation band include the western Kenai Peninsula North of Clam
Gulch, the Western Susitna Valley west of the Parks Highway, and
areas surrounding western Prince William Sound.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
The front exits today, taking the precipitation and wind with it,
followed by clear and colder air as high pressure sets up over
the mainland. The front will move out of the area tonight with the
steady snow (Kuskokwim Delta/Valley), and rain (Greater Bristol
Bay) ending from west to east through the evening. A short-lived
showery regime (snow) will affect the Delta this evening. High
pressure builds in behind the front/trough Tuesday which will lead
to light winds, clearing sky and areas of fog into Wednesday
morning.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
Several weak disturbances bring snow showers from
Unalaska/Pribilofs and east while a new front enters the Western
Aleutians. The front will be max gale/min storm force, and mostly
be rain, but could begin as snow late tonight. It slowly
progresses eastward, stalling out near the central Bering on
Wednesday.

&&

.LONG TERM FORECAST (Days 3 through 7)...
There is very good agreement that a omega block setting up over
the Mainland late this week will bring a period of benign weather
to much of the area into the upcoming weekend. This omega block
will be much warmer than is typical for this time of year as it
forms in deep southerly flow over the Bering. As a result, much of
the Mainland should see near to above normal temperatures
(especially over the Southwest Mainland), sunny skies, with no
precipitation expected. In this pattern the primary concern will
be for the development of fog/stratus under the ridge, however
with broad offshore flow this likely will not be too widespread.

Over the Aleutians and Bering to the west of the Pribilofs
Islands, a nearly stationary frontal boundary will setup on the
western edge of the omega block. This will bring persistent gale
force winds and rain to much of the Central-Western Aleutians from
the middle of this week into the weekend.
