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 Dec 2, 4:30 PM AKST, 10 hours 52 minutes earlier.

Area forecast discussion, Dec 2, 4:30 PM AKST, 10 hours 52 minutes before
Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
430 PM AKST Sun Dec 2 2018

.ANALYSIS AND UPPER LEVELS...
Highly amplified dynamic flow dominates the upper levels across
most of the Alaska region and North Pacific. A compact surface
low is retreating northward along the western Alaska coast. Strong
pressure rises on the back side of the low are contributing to
gusty southerly winds and blowing snow across portions of the
Kuskokwim Delta despite some fairly warm temperatures (low to mid
30s). In any case, snow is tapering to scattered snow showers
behind the low.

As the upper level wave associated with this low exits northward,
a separate wave crossing the Bering Sea is dropping into the back
side of the trough and in the process of phasing with the primary
trough, which extends southward to the Alaska Peninsula and into
the Pacific. A jet streak just ahead of the trough is oriented
from south to north across the western Gulf and up to Cook Inlet
and the Susitna Valley. Water vapor imagery shows moisture
streaming northward from the Pacific toward Southcentral. Beneath
this, a nearly stationary surface front sits over the western
Gulf. This sets the stage for development of a north-south
oriented band of precipitation through this region as the
strengthening upper trough approaches from the west this
afternoon. One last important player in this unfolding event is
temperatures. Marginally warmer air is advecting northward from
the Gulf into Southcentral. Low level southeast winds across the
Kenai and Chugach Mountains are also leading to locally warmer air
in the lee of the mountains. Thus, the airmass is warm enough to
produce mainly rain from the Kenai Peninsula to Anchorage and the
Matanuska Valley. The wind forecast will be key to the temperature
and precipitation type for later today.

Meanwhile, a very large deep low over the North Pacific is lifting
northward toward the Aleutians and Bering Sea. A ship ob from this
morning indicates hurricane force winds in the cold sector of this
low (west of low center). Satellite-based wind estimates indicate
storm force winds along the occluded front approaching the
Aleutian chain. Winds are rapidly increasing along the central
Aleutians from Atka to Adak wit rain overspreading the region.

&&

.MODEL DISCUSSION...
Model guidance is struggling with the details of the unfolding
snow event over Southcentral Alaska. In particular, there is poor
run-to-run consistency of the placement and orientation of the
upper trough which affects the location of surface frontal band of
heavier precipitation along with the strength of winds across the
Kenai and Chugach Mountains and resultant air temperatures. These
differences have huge ramifications on the snow forecast for
Anchorage and the Matanuska Valley. Will closely monitor trends
this afternoon to see which solution might be most accurate.

Models have a better handle on the large system out west as it
tracks into the Bering and as occluded front spreads north and
east to Southwest Alaska Monday night and Tuesday. Overall
forecast confidence is higher and only minor changes have been
made to the existing forecast.

&&

.AVIATION...
PANC...This forecast is quite challenging with uncertainty in
transition from rain to snow. However, no matter the exact
timing, expect a period of IFR conditions once precipitation does
change to snow. Low clouds will likely linger after snow ends
tomorrow morning, but it looks like enough low level flow will
develop by midday to help erode any existing clouds.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
Tricky precipitation type forecast on deck tonight. The Kenai
RADAR is beginning to fill in over the western Peninsula despite
the southeasterly winds across Anchorage. The Turnagain winds
currently have warmed temperatures in the mid 40's across the
Bowl, which will have implication on the precipitation type
tonight. As the upper trough approaches, expect precipitation to
begin as rain (we've already had some this afternoon) this
evening. However, the winds should subside later this evening. The
diminishing winds and precipitation intensity from the incoming
trough/cold advection should lead to a quick changeover to snow
before midnight. The heaviest snow should be between midnight and
3am when the coldest air arrives and upper trough passes overhead.
Given the warm starting temperatures, the snow should be heavy
and high moisture. Snow will taper off quickly in the early
morning, ending from Anchorage through the Susitna Valley by 6am.

Cordova remains warm enough for rain and will stay that way
through the event. Valdez should remain in the cold air for the
majority of the time. Once the surface low passes into the Copper
River Basin tomorrow morning, a brief period of southwesterly
winds could bring a surge of warm air up into Port Valdez and
change snow to rain before precipitation ends. The Copper River
Basin will remain dry through the early morning hours, but will
see snow start by mid-morning with several inches of accumulation.

Beyond tomorrow, a strong frontal boundary approaches on Tuesday.
There isn't a huge slug of warm air with the front, but deep layer
southeasterly flow should keep the lee side of the Chugach dry.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 through 3)...
Snow showers are possible through late tonight, along with rain
during the evening, as upper level short waves move overhead from
a parent low over the Bering Strait. The trough exits the area
across the Central Interior by Monday morning. Only minor
accumulations are expected tonight; however snow amounts up to 5
inches are likely along the Western Alaska Range. A ridge builds
across the southwest as the low exits the region overnight, so
included a mention for patchy fog tonight.

The next front entering the the southwest late Monday night will
be the biggest forecast challenge through Wednesday as winds are
expected to increase rapidly as the boundary moves across through
Tuesday afternoon. The strongest winds are expected along the
mountain Ranges of Bristol Bay with gusts between 50 to 70 mph
anticipated. Mixed precipitation is expected along the boundary as
it pulls through. Strong downsloping winds limits precipitation
during this event across the Southwest.

There is still a bit of uncertainty on the evolution of this
storm. Details on moisture/temperature profiles and differences
in timing of the shortwaves will be monitored closely through this
event.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 through 3)...
The storm system approaching the Central Aleutians this evening
brings Storm force winds across much of the marines along the
chain through Monday. Hurricane force winds were added for the
Western Aleutians marine forecast as the occluded front moves over
the chain. The peak time frame for winds will be a relatively
long duration as the stacked system stalls through Tuesday.
Tuesday night through Wednesday this system begins to fill on a
crawling eastward track. Strong waves of energy around this storm
will bring re-enforcing gusty winds through Wednesday.
Precipitation with this system will primarily be rain along the
southern Bering with mixed precipitation along the north and
western waters as cooler temperatures wrap along the core of the
low.

&&

.LONG TERM FORECAST (Days 4 through 7)...
Beginning Wednesday evening, there will be an active weather
pattern in place as a very deep longwave trough sets up over the
Bering Sea and Pacific, extending to around 30N. The main moisture
stream will be directed at southern Alaska, with a continued warm
pattern in place as 850 temps will be around -1 to -3C, albeit
cold enough for some snow in parts of the interior such as the
northern Susitna Valley and the Kuskokwim Valley. Sometime
Thursday, all the global numerical models are strongly hinting at
a basal shortwave moving north toward the Gulf of Alaska, rapidly
deepening as it does so. Currently this low looks to be a strong
gale force and potentially low end storm force along the barrier
jet, but it will also be bringing another slug of warmer Pacific
air, enhanced by the above average SSTs. With that said, Thursday
and into Friday look warmer and wet, especially along the coast.
Heading into the weekend, the longwave trough slowly shifts east
so wetter weather will also shift east, and slightly cooler air
will filter into the mainland. Much uncertainty develops by
Saturday as the ECMWF disagrees with the colder Canadian GDPS and
18z GFS. With that said, ensembles do agree more in general that a
split trough may develop, allowing for arctic air to seep south
and interact with the warm moist Pacific air. Should this happen
increased snow threats will be possible. Stay tuned...

Over the Bering Sea, with the broad cyclonic flow associated with
the aforementioned trough moving east, expect northerly flow to
last through Saturday before a series of fronts and/or a stronger
