What forecasters said that day

The local office's own words before this blizzard warning 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 blizzard warning went out at Dec 19, 3:55 AM AKST, 10 hours 20 minutes earlier.

Area forecast discussion, Dec 19, 3:55 AM AKST, 10 hours 20 minutes before
Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK
355 AM AKST Fri Dec 19 2025

.SYNOPSIS...
Multiple systems are expected to move over the West Coast over the
next several days. Another system will be moving south from the
Arctic today, providing the North Slope with another round of snow
and gusty winds. Intermittent cloud cover looks to continue across
the Interior, which may provide some isolated flurries at times.
Confidence remains low to moderate for the winter storm Tuesday
through Thursday next week. Snowfall forecasts remain uncertain as
the models continue to zero in on a track for this system.

&&

.KEY WEATHER MESSAGES...
Central and Eastern Interior...
- Cold temperatures persist with lows in the -20s to -40s across
  the Interior. Some areas continue to see low-lying clouds,
  providing some flurries and slightly warmer temperatures. When
  clouds dissipate temperatures will fall again.

- Next week sees a chance for a brief warmup as snow and breezy
  winds disrupt the cold in the Central Interior Tuesday through
  Thursday. Confidence is still too low to give a good snowfall
  estimate, but snow is likely to be fluffy.

West Coast and Western Interior...
- Snowfall along the Chukchi Sea Coast throughout the rest of the
  morning, Moving across the middle Yukon and Upper Kuskokwim.
  Total accumulations between 2" and 4" are expected.

- Another system will bring a N-S oriented front across the West
  Coast by early Sunday morning into Monday.
	 - Additional snow of 1 to 3 inches expected from the front.
	 - Gusty southerly winds through the Bering Strait and along the
    Chukchi Sea coast may lead to periods of reduced visibility
    due to blowing snow.

- Another system will move over the Seward Peninsula late Sunday
  night, bringing more snow across the West Coast. Additional snow
  accumulations between 2" and 4" can be expected across the West
  Coast.
 	 - Heaviest snowfall will be in the higher terrain of the Seward
     Peninsula.

North Slope and Brooks Range..
- Additional snowfall for the Eastern North Slope on Friday.
  Accumulations between 1" and 3" can be expected along with
  westerly gusts between 20 and 30 mph. Snowfall increases further
  east. Winds diminish Saturday.

- Southerly winds increase late Saturday night into Sunday Gusts
  of 20 to 30 mph possible west of Point Barrow and up to 20 mph
  possible east of Point Barrow.
	 - Winds will increase with gusts between 30 and 40 mph around
    the Lisburne Peninsula.

- Another system approaches the West Coast Tuesday bringing
  widespread snowfall and some gusty winds. Confidence is too low
  to give a good snowfall estimate at this time.

&&

.FORECAST ANALYSIS AND DISCUSSION...
A more active pattern is looming over the horizon as the holiday
approaches. A system will continue to move SE over the Kuskokwim
throughout the afternoon. Another system will be moving onshore,
over the NE Arctic Coast later this afternoon bringing additional
snowfall. Winds will increase over the far NE Arctic Coast as the
system moves over, which may reduce visibility through early
Saturday morning. These two systems will continue to provide waves
of energy across the Interior allowing for Intermittent clouds and
flurries.

As the low from NE Arctic moves to to norther portion of the
Brooks Range, this will provide upslope flow to the Upper Tanana
and Fortymile Country. Snow accumulations between 1" and 2" can
be expected on Saturday.

Behind the Arctic System, a good portion of the Interior will see
some partial clearing which will allow for a decrease in
temperatures Saturday night into Sunday. Minimum temperatures
between -40 and -50 for much of the Interior valleys throughout
the weekend if skies remain clear and winds remain calm.

Looking back to the West Coast, another front, with a N-S
orientation, will begin to move onshore by Sunday morning. This
will bring another round of widespread snow across the West Coast
and Western Interior. Another system will begin to dig SE from
the Chukchi behind this front which will bring another round of
snow for the West Coast and Western Interior on Monday. Both of
these systems will be working to breakdown high pressure that will
be forming over the Interior with the previously mentioned
clearing.

&&

.EXTENDED FORECAST DAYS 4-7 (Monday night through Friday)...
The extended portion of the forecast continues to show the
possibility for a winter storm to move across the state. The
previous system will continue to move SE from the West Coast.
Another system will follow shortly behind with a surface low
tracking westerly along the North Slope coast. A front will extend
across much of the state, eventually pushing out the ridge over
the Interior and setting up a new pattern of west-southwest flow.
This will make conditions favorable for moderate snowfall across a
large portion of the state.

In regards to the upper-level pattern, everything will be driven
by how quickly the ridge breaks down over the Interior. Recent
runs of deterministic models show the ridge holding its strength
longer but eventually leading to the main snowfall event on
Christmas Eve.

Coastal Hazard Potential Days 3 and 4...None
