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.

Area forecast discussion, Sep 18, 5:55 AM AKDT, 8 hours 5 minutes before

Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK
555 AM AKDT Sat Sep 18 2021

.SYNOPSIS...
An active weather pattern will continue through the weekend as
a transition occurs to more winter like weather in the Interior.
Most of the weather will be driven from a series of low pressures
that will develop off the central and northwest Arctic Coast over
the next several days. These lows will send a couple of cold
fronts that will move across the Interior today and then Sunday
night and into Monday morning, with increasing potential for snow
across the region. The North Slope and Brooks Range will remain
under snowy conditions through the weekend.

&&

.DISCUSSION...
The upper level pattern continues to be dominated by an upper
level longwave trough across northern Alaska. A closed low is
located just to the northeast of Wrangel Island and will move just
offshore of Utqiagvik by Sunday morning. This upper level feature
will remain in the general vicinity in the Beaufort Sea going into
the work week.

A shortwave associated with the upper level closed low is
situated north to south from Nuiqsut to McGrath and will move
across the Interior today and be across the AlCan border by
Sunday morning. A second shortwave will push across the West Coast
on Sunday before reaching the Interior by Monday morning and
stalling west of Fairbanks.

At this point, a second closed low area in the Gulf of Alaska
begins to interact with the second strong shortwave moving across
the Interior on Monday. Models differ on how these two features
interact, thus continuing to cause uncertainty in what to expect
beginning Monday afternoon, particularly with precipitation in the
eastern Interior.

Central and Eastern Interior...
A couple of cold fronts will move through the area going into next
week. The first front will move through today, bringing primarily
rain, with snow in higher elevations of the Alaska Range and
southeastern Brooks Range. As this front exits the state this
evening, a second front will begin to push in from the west tonight.
This front will bring a more widespread opportunity for snow all
the way to valley level in spots of the Interior through Monday
morning. Heavier snow will remain to the north along the Dalton
Highway, hence the issuance of Winter Weather Advisories for snow,
with accumulations of 2 to 5 inches. Areas south and east of this
area will see anywhere from a dusting up to one inch, primarily
above 1000 feet. As a result of these fronts, expect below normal
temperatures by Monday.

North Slope and Brooks Range...
A series of surface low pressures will bring continual active
weather across the North Slope and Brooks Range going into next
week. Primarily northwest flow across the northwest Arctic Coast
will result in snow showers in this region and to the northwest
Brooks Range over the next several days. Snow accumulations of 2
to 6 inches along the coast, with amounts up to 12 inches along
the western Brooks Range expected through Monday night. Further
east, 3 to 6 inches also possible along the Dalton Highway through
Atigun Pass. Winds out of the northwest expected to increase with
the development of a surface low near Utqiagvik by Sunday night
bring strong onshore flow with gusts to 40 mph through Monday.
Temperatures expected to remain below normal going into the middle
of next week.

West Coast and Western Interior...
Much like the rest of northern Alaska, the portions of the West
Coast and Western Interior will receive snow from the Seward
Peninsula north through tomorrow. Total accumulations up to an
inch expected, with larger amounts along the foothills of the
Brooks Range. Strong northwest winds gusting to 35 mph will bring
elevated surf along the Chukchi Sea Coast and Kotzebue Sound
Coasts beginning Sunday afternoon and lasting until Monday
morning. Otherwise, relatively quiet conditions elsewhere, with
temperatures trending down to well below normal by Monday.

Coastal Hazard Potential...Elevated surf of 1 to 2 feet expected
along the Chukchi Sea Coast and Kotzebue Sound Coast as strong
northwest winds develop on Sunday. The elevated surf is expected
to last from Sunday afternoon and into Monday morning.

&&

.HYDROLOGY...
No concerns at this time.
