Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK
1230 PM AKST Mon Dec 8 2025

.SYNOPSIS...
Cold weather is continuing to settle into the Interior this
afternoon. With a transition from cold wind chills that happened
over the weekend, to colder air temperatures through Thursday.
Wednesday night will be the coldest night across much of Northern
Alaska. A weak arctic front will bring snow and low stratus
across the North Slope today and tomorrow. Some relief from the
cold temperatures is expected Thursday night and Friday as a low
pressure moves in from Siberia, brining warmer temperatures and
light snow chances.

.KEY WEATHER MESSAGES...
Central and Eastern Interior...
- Overnight temperatures across the Eastern Interior valleys will
  be in the 30s and 40s below 0. The Upper Tanana valley could see
  temperatures at or below -50 Wednesday night.

- Winds will slowly weaken in the higher terrain today, and will
  remain calm through the week.

- A quick moving feature will bring a round of clouds through the
  Eastern Interior tonight. This could help keep the overnight
  lows from reaching their coldest potential. By Tuesday night
  expect clouds to fully clear across the Eastern Interior.

West Coast and Western Interior...
- Cold and calmer weather persists with lows in the single digits
  above/below zero along the coast and teens to about 30F below
  zero in the Interior until Thursday.

- Snow showers are possible around Kotzebue Sound and on the
  Seward Peninsula starting Thursday morning. Snow accumulations
  would be light with only 1" to 3" expected.

- Temperatures will quickly warm Thursday with lows in the teens
  to 20s above 0 along the coast, and single digits below 0 in
  the Western Interior. This warming trend will continue into the
  weekend.

North Slope and Brooks Range..
- A front brings clouds and areas of snow showers to the region
  this afternoon and into Tuesday. Light snow will persist into
  Wednesday. Only 1" to 2" of snow is expected with this front.

- Temperatures will cool Tuesday night as arctic air follows the
  weak front. Low temperatures will go into the teens below 0.

.FORECAST ANALYSIS AND DISCUSSION...
Building high pressure in the Bering Sea is continuing to
translate into the Interior. An area of low pressure in the
Canadian Archipelago is connected to the triple point low in the
Gulf of Alaska via a stationary front. The high pressure from the
Bering is continuing to bring northerly winds into the Interior
keeping the 850 mb temps into the teens to 20s below 0. A series
of shortwaves will move overtop the ridge axis into the Interior
later tonight. This will bring a quick round of cloud cover to the
Eastern Interior, which could help to mitigate the cold
temperatures in the valleys tonight and tomorrow. By Wednesday
night an Arctic Front will have moved across the Interior bringing
another round of reinforcing arctic air. While the North Slope
could see light snow with this front, the Interior will be too dry
at the surface to see any accumulation precipitation. The west
coast will see another low pressure move into the Northwestern
Interior Thursday morning. This will bring a brief change to this
cold and dry pattern, and it`s impacts will discussed in the
"Extended Forecast Section".

.EXTENDED FORECAST DAYS 4-7...
Wednesday night will begin to see a quick moving low pressure move
overtop the area of high pressure in the Southern Being. This low
will track east into the Arctic by Thursday, bringing snow,
warmer temperatures, and increasing winds across Northern Alaska.
Snow chances for the Eastern Interior will increase Thursday night
and will go into Friday night. Increasing west-northwest winds
across the Northslope Thursday through Saturday, could lead to
areas of blowing snow. Any snow accumulations with this system
will be light. The Y-K Delta coastline could see an area of mixed
precipitation as southerly flow aloft bring temperatures aloft
near freezing. There is a brief 12 hour window on Thursday that
either sleet or freezing drizzle is possible. These chances are
low but non zero.

Looking towards Sunday we will see a return of frigid arctic air.
Another round of 30s to 40s below 0 is possible in the Interior
starting Sunday night and going through most of next week.
Depending how quickly the cloud cover clears Sunday, would dictate
how quickly we can cool down. This pattern looks to remain dry
with the exceptions of snow showers along the West Coast and North
Slope coastlines.

Coastal Hazard Potential Days 3 and 4...
Gusty southwesterly winds through the Bering Strait Thursday could
bring higher waters into Kotzebue Sound. This would potentially
lead to water on top of the sea ice from Point Hope to Kotzebue
Thursday and Friday.
