Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK
433 AM AKST Mon Dec 8 2025

.SYNOPSIS...
Windy conditions across parts of the Interior will be ending
today, with colder weather setting back in. A round of light snow
is expected to move across the North Slope from this afternoon
through Wednesday, but accumulations are likely to be limited.
Elsewhere, temperatures ranging from the single digits below zero
in western coastal locations to the -30s if not colder in
Interior valleys will be possible from tonight through Wednesday
night. Beyond that, another system is possible on Thursday and
Friday which could bring light snow to much of Northern Alaska.

.KEY WEATHER MESSAGES...
Central and Eastern Interior...
- With minimal cloud cover, lows in the 30s and 40s below zero
  persist in colder/valley locations through much of the week.

- Wind will continue to diminish through today, with nearly calm
  winds by this evening.

- Blowing snow will persist along the Richardson and Parks
  Highway in the southern slopes of the AK Range while gradually
  decreasing today as winds weaken there.

West Coast and Western Interior...
- Breezy conditions will gradually weaken today, with generally
  weak or calm winds tonight.

- Cold and calmer weather persists thereafter with lows in the
  single digits above/below zero along the coast and teens to
  about 30F below zero in the Interior through much of the week.

North Slope and Brooks Range...
- Cold and breezy conditions continue.

- A front brings clouds and areas of snow to the Slope and Brooks
  Range on Monday and Tuesday. Light snow will persist into
  Wednesday.

- Accumulations look to be around 1 inch or less along the coast
  and up to 2 inches in Atigun and Anaktuvuk Passes.

.FORECAST ANALYSIS AND DISCUSSION...
A 545 dm ridge is centered over the Bering Sea, with a 497 mb
trough over the Canadian Archipelago. Clear skies are in place
across roughly the southeastern half of mainland ALaska, with 850
mb temperatures over eastern areas well into the -20s. Moving into
this evening and tonight, a shortwave will ride along the top of
the ridge and bring periods of snow to the North Slope and
northeastern Interior through Wednesday before moving out of the
area. Colder air will move into the North Slope from the
northwest behind the snow with a surface cold front from Monday
evening into Tuesday, with increasing westerly winds across the
Arctic Coast, especially in eastern areas. Drier conditions are
likely across the Interior with limited cloud cover in place
before additional chances for snow return Thursday.

&&

.EXTENDED FORECAST DAYS 4-7...
Chances for snow and, in the YK Delta region, potentially some
mixed precipitation/rain, will return to much of Northern Alaska
beginning early Thursday as the ridge over the Bering and Chukchi
Seas shifts east and a low on its northern edge shifts off of
Siberia into the Arctic. After the low moves off of Siberia, it
will likely track east along or over the Arctic coast of Alaska,
bringing windy conditions there (and potentially blowing snow with
some visibility restrictions). This may also bring with it a
broad area of cloudy conditions with potentially a few inches of
snowfall to much of Alaska north of the Alaska Range. This would
also yield warmer weather, with many areas rising back into the
single digits above zero (double digits in western locations).
Colder and drier conditions will resume by the latter half of the
weekend, with low temperatures broadly in the -20s and -30s
again.

Coastal Hazard Potential Days 3 and 4...None
