What forecasters said that day

The local office's own words before this brisk wind 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 brisk wind advisory went out at Dec 20, 4:52 AM AKST, 51 minutes earlier.

Area forecast discussion, Dec 20, 4:52 AM AKST, 51 minutes before
Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK
452 AM AKST Mon Dec 20 2021

.SYNOPSIS...Major storm system has moved into the state and will
impact most of the forecast area into Monday before it starts
improving in the west. Heavy snow in the Interior tonight and
Monday. Rain from the Seward Peninsula south will transition back
to snow tonight. Winds on the West Coast trending down overnight,
while in the Arctic they will trend down Monday. Elevated water
levels on the West Coast will be trending down this evening. See
the latest Warnings, Watches, and Advisories at
www.weather.gov/fairbanks for details.

&&

.DISCUSSION...

Models...19/12Z solutions continue to be uncooperative with the
ongoing storm that is impacting most of the forecast area already.
All of the solutions missed on the timing of the precipitation
as it moved in. Hopefully the will not miss on the snowfall
amounts. They did have a decent handle on temperatures in the
southwest areas where it warmed above freezing and rain is
falling. Solutions have temperatures slowly moderating back below
freezing with precipitation returning to snow to the southwest of
Fairbanks. Current solutions are showing a slight chance of rain
overnight extending northeast to Fairbanks, but it is very slight
at this time. With the surge of warm air there has been a mix of
precipitation and going forward that will be the challenge through
Monday, but chances of rain decrease with time as those
temperatures moderate. Since the system cam in faster, will be
trending the heavy snow down a bit sooner, but still expecting
light snow into Tuesday morning before it tapers off. Will go with
a blend of solutions as they are similar, but will kick the
probabilities up to categorical across most of the forecast area
again today. Solutions finally agree on precipitation amounts so
will also use a blend for the remainder of the event. Snow ration
will range from around 8/1 to 15/1 for most areas. Warm
temperatures will keep rain from freezing on power lines and most
objects. Rain will be falling into snow in most areas, but in
areas without snow, rain is expected to freeze as it contacts the
frozen ground.

Aloft...At 500 hpa...Ridge axis extends northeast over Kodiak
Island to Tanana to Utqiagvik and north. A 486 dam low has moved
over Siberia with a trough extending northeast over Wrangel Island
then south over the Bering Strait to the Central Aleutians. A
second trough extends from the low southeast over the Gulf of
Anadyr, then south over the Dateline. Monday morning the ridge
axis will be over Prince William Sound to Delta Junction to
Demarcation Point then north. The trough pushing into the ridge
extend east from 486 dam low near Wrangel Island over the Chukchi
Sea and nearshore waters to Deadhorse, then south over Fairbanks
to the Shelikof Strait. Second trough will extend from the low
over the Chukchi Sea to Point Lay, then south to Selawik and
Anvik. Strong southwest flow will extend from the Northwest
Pacific over the Bering Sea into the Eastern Interior. Another
shortwave will develop near the Dateline over the Bering Sea
Monday morning. Monday afternoon a weakening ridge axis will be
over the AlCan as the second trough is over the Eastern Interior
pushing over it. The low near Wrangel Island will be 100 nm
northeast of the island. The trough that developed over the
Dateline will come in phase with another trough moving around the
low and move over the West Coast as the flow aloft turns a little
more from the west. At 850 hpa...-10C isotherm has been pushed
north of the Brooks Range and the -20C isotherm is well north of
the Arctic Coast. The 0C isotherm is over the Lower Yukon Delta
Seward Peninsula, and Kotzebue Sound. As the ridge aloft continues
