Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK
412 AM AKDT Sat Oct 18 2025

.SYNOPSIS...
While the overall pattern is much quieter, chances for snow
continue this weekend and next week as shortwave energy meanders
around the state. The heaviest snow is expected in the Bering
Strait Region as snow showers and squalls bring some bursts of
heavy snow as well as gusty winds. Northern Alaska as a whole
will also be entering a cooler and drier period next week.

.KEY WEATHER MESSAGES...
Central and Eastern Interior...
- Periods of light snow and snow showers continue today then
  diminish in coverage tonight and end Sunday morning.

- Dry and cooler Sunday and Monday with light snow possible along
  the AlCan Border Monday night and Tuesday.

- Temperatures gradually cool this weekend and next week by nearly
  a degree per day. Highs are expected to be in the mid to upper
  20s by the end of the week.

West Coast and Western Interior...
- Snow showers and squalls move into St. Lawrence Island this
  morning, then traverse northeast to the Bering Strait this
  afternoon. Some of these may come with bursts of snow and gusty
  winds up to 35 mph.
- Uncertainty lies with how far east the snow gets. The most
   likely outcome is it stays west of Nome and resides from St.
   Lawrence Island to Teller west, though Nome may see some
   lighter snow showers throughout the afternoon and tonight.
- Snow showers and squalls likely move over the same locations
   through Monday morning before dissipating.

Snowfall totals today through Monday:
- St. Lawrence Island - 4 to 8 inches.
- Teller to Wales - 1 to 4 inches.
- Nome - An inch or less.

- Elsewhere, lingering snow showers and flurries today, turning
  mostly dry tomorrow through Tuesday.

- Temperatures gradually cool this weekend and next week by nearly
  a degree per day. Highs are expected to be in the 20s to near 30
  by the end of the week with the coldest in the Interior.

North Slope and Brooks Range..
- Stratus with areas of fog continue with chances for snow,
  especially west of Nuiqsut today.

- Generally quiet weather persists for the foreseeable future.

- Colder next week with highs in the low to mid 20s along the
  coast and teens/single digits in the Brooks Range. Lows will be
  in the teens to near 20 along the coast and around 0 or below 0
  in the Brooks Range beginning Monday.

.FORECAST ANALYSIS AND DISCUSSION...
A broad trough over Eastern Siberia will continue drive most of
Northern and Western Alaska`s weather moving forward. The most
impactful weather in the short term appears to be in the Bering
Strait Region as snow showers and squalls bring bursts of heavy
snow and wind gusts to 35 mph today through Monday morning. A
trough of low pressure connected to the broad Siberian trough
will detach and become a nearly stationary upper low over SW AK
early next week. This should only bring some clouds and flurries
to SW AK Monday through Tuesday. Otherwise, a shortwave trough
over the Interior keeps chances for light snow through tomorrow
morning with drying conditions tomorrow afternoon and Monday as we
get southerly flow aloft. Monday evening, a low in the gulf will
bring a front with some moisture into the Eastern Interior with
another chance for light snow Monday night through Tuesday.

On the North Slope, the weather will be pretty benign with areas
of light snow and flurries will be accompanied by stratus and fog.

Continued activity in the Gulf will provide shortwaves over the
Central/Eastern Interior through the week. While we don`t foresee
major impacts, there will be snow chances for much of the week.
More details on that below in the extended forecast.

.EXTENDED FORECAST DAYS 4-7...
Generally quiet weather with a cooling trend continuing through
the week. There are no significant hazards in the foreseeable
future expected. One thing we were monitoring yesterday was the
potential for snow in the Eastern Interior by the end of the week.
The feature that would produce that has shifted a bit west on the
latest guidance which would mean that most of the moisture will
get lost in the mountains around Anchorage as well as the Alaska
Range. There will be a lot of changes in the coming days, but
right now it is trending towards something unimpactful for our
area.

Coastal Hazard Potential Days 3 and 4...None
