Area forecast discussion, Apr 20, 6:37 AM AKDT, 4 hours 21 minutes before
Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK
637 AM AKDT Mon Apr 20 2026

.SYNOPSIS...
The remnants of a low are expected to make their way across the
state, bringing scattered snow showers to much of the Interior and
North Slope through Tuesday night. This low is also expected to
create a strong gradient on the West Coast which will support
gusty northerly flow and periodical blowing snow. A brief break in
precipitation and wind is expected across Northern Alaska. Following
this short stretch of quieter weather, another low is expected to
move into the southern Bering Sea early Wednesday morning. Mixed
precipitation and freezing rain will be likely over the YK Delta
with scattered snow and rain showers expected to persist for much
of the state through the upcoming weekend. Strong easterly/
northeasterly winds are anticipated to return on the West Coast,
with strong gusts at high Interior elevations as well. The
associated warm front will support warmer temperatures later in
the week, with many locations seeing high temperatures above
freezing.

&&

.KEY WEATHER MESSAGES...
Central and Eastern Interior...

- Scattered light to moderate snow showers will continue across
  the Interior and Alaska Range early this week, tapering off by
  midweek ahead of another system moving in mid-to-late week.

- Additional snowfall amounts through Tuesday are expected to be
  around 1-4" in the Eastern Interior valleys and 3-8" in the
  mountains and valleys west of the Dalton and Parks Highways.
  Locally higher totals are expected in the Alaska Range, where
  around 8-12" of snow is expected for higher elevations of the
  Parks and Richardson Highways with locally higher totals above
  pass level.

- Winter Weather Advisories and Winter Storm Warnings remain in
  place for the Central Interior and Alaska Range through Monday.

- Looking ahead, high confidence supports a strong low pressure
  system moving north through the Bering Sea mid-to-late week
  which will eject a series of fronts. This system will bring in
  mixed precipitation chances, gusty winds (particularly through
  Alaska Range Passes), and the warmest temperatures so far this
  year.

West Coast and Western Interior...

- Scattered light to moderate rain and snow showers will continue
  across the Western Interior and West Coast south of and
  including the Seward Peninsula. These showers will taper off
  today into tomorrow west to east ahead of another system moving
  in mid- to- late week.

- Additional snowfall amounts through Tuesday will range from
  around 1-4" along the southern West Coast to around 4-8" in the
  Western Interior. A rain/snow mix will remain possible farther
  south.

- Strong winds continue through the Bering Strait to St. Lawrence
  Island, with wind gusts up to 50 mph leading to areas of blowing
  snow.

- Winter Weather Advisories and Winter Storm Warnings remain in
  place for portions of the Western Interior and Interior Norton
  Sound, in addition to the Bering Strait Coast through today.

- Looking ahead, high confidence supports a strong low pressure
  system moving north through the Bering Sea mid-to-late week
  which will eject a series of fronts. This system will bring in
  mixed widespread precipitation chances, gusty winds, and the
  warmest temperatures so far this year.

North Slope and Brooks Range..

- Scattered light snow showers will continue to lift north into
  the Central/Eastern Brooks Range and Southern Arctic Plains
  through today and tomorrow. Snow accumulations around 1-3" are
  expected in this region. Snow chances will subside midweek.

- Gusty winds continue for the Western Brooks Range/Arctic Coast,
  leading to areas of blowing snow and reduced visibility at
  times. Breezy winds will expand east across the North Slope and
  Brooks Range today into tomorrow, strongest along the Arctic
  Coast.

- Looking ahead, high confidence supports a strong low pressure
  system moving north through the Bering Sea mid-to-late week
  which will eject a series of fronts. This system will bring in
  mixed widespread snowfall chances (lower chances for mixed
  precipitation), gusty winds, and the warmest temperatures so far
  this year.

- This week will see a significant warmup from lows in the double
  digits below zero temperatures Monday morning to 20s/30s above
  zero for highs later in the week.

&&

.FORECAST ANALYSIS AND DISCUSSION...
Today through Wednesday Night.

An upper level low is expected to linger over much of Northern
Alaska through Tuesday afternoon. The presence of this low will
allow for cold and dry conditions and strong winds to persist on
the North Slope. Precipitation-wise, snow chances are likely to
continue for most of the Interior through late Tuesday night as
the low continues to transport moisture into the area. Around the
early Tuesday morning time frame, moisture becomes wrapped in the low
center's circulation as this system moves across Northern Alaska.
As a result, rain and snow showers are likely for the North Slope
through Tuesday and early Wednesday. This current system is also
expected to support strong northerly winds through the Bering
Strait and over most of the West Coast. Southerly gap winds
through the Alaska Range passes are also expected to remain
elevated for the earlier portion of this morning.

The outer edge of an upper level ridge begins to move into
Southern Alaska Tuesday morning. A tight gradient between the low
and the ridge is expected to support strong westerly winds in the
Interior with the strongest gusts at the highest elevations.
An extratropical cyclone begins to push the ridge to the
northeast Wednesday morning. The progression of this system's
triple point is expected to bring strong easterly/northeasterly
winds to the West Coast and will gradually build a strong south to
north gradient in the Gulf. This pattern will support strong gap
winds through the Alaska Range passes and significant downsloping
into the Interior. As a result, Interior high temperatures are
expected to increase from the mid 30s/low 40s above to the low to
mid 50s by Thursday. The associated warm front with this system is
expected to assist with moisture transport across the state.
Mixed precipitation is likely to start over the YK Delta area
Wednesday morning with brief chances for freezing rain. Scattered
snow and rain showers are possible for the Interior through
Thursday night. More scattered precipitation chances are expected
throughout the week as the cyclone gradually breaks apart and
dissipates.

&&

.EXTENDED FORECAST DAYS 4-7...
Thursday through next Sunday.

An extratropical cyclone will approach Southwest Alaska around the
Wednesday morning time frame. Scattered mixed precipitation is
likely for the Yukon-Kuskokwim Delta region through the weekend,
with scattered rain/snow chances for the Interior and Brooks Range
likely as well. The orientation of this system with the upper
level high is expected to create a tight south to north gradient,
significantly warming temperatures across the state with high
temperatures above freezing for many locations. Strong
easterly/northeasterly winds are expected for high elevations in
the Interior as well as a large portion of the West Coast through
Friday night.

Coastal Hazard Potential Days 3 and 4...None
