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 Fairbanks, AK wrote its last area forecast discussion before this small craft advisory went out at Sep 30, 1:38 PM AKDT, 15 hours 9 minutes earlier.

Area forecast discussion, Sep 30, 1:38 PM AKDT, 15 hours 9 minutes before
Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK
138 PM AKDT Thu Sep 30 2021

.SYNOPSIS...
Winter is starting early for the Interior as another winter storm
is primed to move across the Alaska Range and north into the
Eastern and Central Interior, beginning Friday and continuing
through the weekend. Significant snowfall will likely fall from
the Alaska Range north through the Interior, and across the Brooks
Range to the eastern North Slope. Out west, strong north winds
and snow showers will impact the coastal areas.

&&

.DISCUSSION...

Upper Levels and Analysis...
There is a powerful low center over the western Bering Sea diving
south toward the Aleutian Chain. A triple point low is forming
along the eastern edge of the larger trough, and this is moving
into the Gulf of Alaska this morning. A weak shortwave trough is
crossing the AK Range with light snow across the Eastern AK Range
and into the Fortymile highlands. The arctic trough is firmly
planted over the Mainland, with an onshore gradient favoring light
snow showers currently over the North Slope.

Model Discussion...
The numerical models are in very good agreement with the large
scale pattern, but in less agreement with the smaller scale
details as two waves of energy lift northwest into the Interior
from the Gulf of Alaska. The issue of concern is the discrepancy
of the leading triple point low moving into the Eastern Interior
tomorrow, and just how far west it retrogrades. This in turn
impacts the next low and how far west it moves on Saturday and
Sunday. The NAM and ECMWf and Canadian models are all in good
agreement bringing a band of snow to the Eastern Interior
including the Tanana Valley and Alaska Range, while the GFS splits
the trough in two, sending energy much farther east, which brings
in 1/4 the amount of snowfall through the weekend. This forecast
is tossing that solution out, thus going with much more snowfall
for the Interior through 72 hours.

Central and Eastern Interior...
Snow is expected to return, the first round coming tomorrow midday
and into the evening a leading front from the Bering Sea shifts
inland. Snow will cross the Eastern AK Range tonight, then move
into the Tanana Valley, Yukon Flats, and Minto Flats by the
afternoon. There remains some discrepancy with this front and just
how fast it rotates through, but the general thinking is there
will be a good burst of snow as it moves through, which would be
around midday into the evening for much of the lower and middle
Tanana Valley. Expect 1-3" with this system.

Attention turns to another low moving into the Interior, this time
from the Yukon, which will bring a round two of snow, but over a
much broader area and for a longer duration, beginning Friday
night and persisting into Sunday. Expecting heavy snow for the
Eastern Ak Range and Fortymile, with moderate snowfall into the
Tanana Valley and west, with upwards of 8-10" possible across parts
of the Taylor, AK Highway, and Richardson Highway. This storm
through Sunday looks to bring a more widespread snowfall than the
previous, with locally heavier snowfall than the last early season
storm.

West Coast and Western Interior...
Quiet weather for the most part, with some inland stratus and
patchy fog through today. Thereafter, the flow becomes strongly
out of the north over the coast, bringing gale force wind gusts
into the Yukon Delta, Saint Lawrence, and most of the Seward
Peninsula. Expect snow squalls/showers to be very active across
the Yukon Delta and Saint Lawrence, as well as over the Bering
Coast. North winds will gradually slacken Saturday.

North Slope and Brooks Range...
Active weather pattern as more snow is on the way. The first wave
of accumulating snow will move over the eastern Arctic Coast
tonight, with heavier snow spreading west to Umiat and Barrow
Saturday. Expecting potential accumulations of 6-9" of snow over
the eastern Arctic, which will include the Dalton Highway. Expect
some areas of blowing snow over the eastern Arctic where northeast
winds will increase into the 20-30 mph.

Coastal Hazard Potential Days 3 and 4...There is increasing threat
that a west coast low will bring some elevated waters to Norton
Sound and the Yukon Delta Tue and Wed. Strength, track, and
impacts are harder to call. For now, the threat is noted, but the
impacts do not look significant at this time as the storm is not
overly strong. Stay tuned.
