Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK
455 AM AKDT Sat Apr 25 2026

.SYNOPSIS...
Most of Northern Alaska remains under warm southerly flow with a
ridge over western Canada and longwave trough over the Bering
Sea. A shortwave trough is moving north over Northern Alaska
bringing rain and snow showers today. There is a slight chance for
freezing rain with little to no ice accretion from Fort Yukon to
Arctic Village this morning. Sunday in the Interior will be
tranquil and mild but a low in the Bering Sea will bring a front
to the West Coast. This front will provide another round of rain,
snow and east winds up to 45 mph. No blowing snow is anticipated
since temperatures will be mild. Otherwise, another wave of energy
will move north from the Gulf of Alaska Monday evening into
Tuesday offering a chance for rain and snow showers once again.
All in all, the weather is active, but not too impactful for most
of the area.

.KEY WEATHER MESSAGES...
Central and Eastern Interior...
- Remnant gap winds will weaken through Saturday.

- A front traversing northwards provides rain and snow showers.
  Predominantly rain showers south of the Yukon River and snow
  showers north with a slight chance for freezing rain from Fort
  Yukon to Arctic Village this morning. A drying trend from south
  to north through the afternoon.

- Persistent chinook flow keeps highs near to above average, in
  the 50s and low 60s. Temperatures remain seasonably mild through
  the end of April with a warming trend possible in early May.

West Coast and Western Interior...
- Another Bering Sea low brings easterly winds gusting up to 45
  mph to the YK Delta Coast, southern Seward Peninsula, and St.
  Lawrence Island late Saturday night before subsiding Sunday
  night. This will be accompanied by light rain and snow as well.

- There is potential for an ice shove (ivu) on St. Lawrence
  Island, especially across Maknik Lagoon.

- Rain and snow showers persist through the week. High
  temperatures range from the 40s and low 50s in the Interior to
  mid and upper 30s along the coast.

North Slope and Brooks Range..
- Light snow in the Brooks Range through this evening with an
  additional inch of accumulation possible.

- Areas of light snow and east wind gusts up to 35 mph in Point
  Lay today. Wind weakens tonight then returns Sunday evening.

- High temperatures in the southern Brooks Range rise into the 40s
  to near 50. The northern Brooks Range will range from the mid
  20s to mid 30s. The Arctic Coast will be in the low to mid 20s
  with Point Hope being in the upper 30s to near 40.

.FORECAST ANALYSIS AND DISCUSSION...
The overall pattern won`t be changing much over the next week. An
upper low will remain over the Bering Sea with an upper high over
western Canada. Heading through the day, a low will be moving
over the Western Aleutians and rapidly strengthen to around 955mb
by this evening. Fortunately, this low`s progression northward
will be halted northwest of the Pribilofs as it runs into a high
over the Arctic. The majority of the impacts will come with areas
of rain and snow as well as east winds to 45 mph along the coast.
One thing being monitored closely with this system is the
potential for an ice shove (ivu) across Maknik Lagoon. The
southwest cape up to Powooilak Camp is also exposed, but sea ice
is farther offshore and may not be able to reach the coast before
winds weaken.

Farther east, there is a high in the Pacific which is around
1030mb and gradually moving east over the next several days. The
combination of a low in the Bering and a high in the Pacific will
continue to provide southerly flow over most of Northern Alaska.
Within the flow will be shortwave troughs that will deliver rain
and snow showers as well as periods of gusty gap winds through the
Brooks and Alaska Range. A potent shortwave is being monitored and
set to arrive Monday night through Tuesday night. Wind gusts on
the north side of the Alaska Range may be in excess of 50 mph with
periods snow on the south side of the pass. Accumulations at this
point are uncertain due to the warm origins of this system, but
there is a chance for accumulating wet snow once again. In the
Interior, expect another round of convective rain/snow showers.
There is a very slight, nonzero chance that this shortwave can
produce the first lightning strikes of the season over the
Interior Tuesday afternoon. A couple of factors that may assist
lightning development is the presence of steep mid-level lapse
rates, bountiful lift and graupel. Graupel is highly electrically
charged when it`s in the cloud and is a strong component in
producing lightning. While the risk for lightning is low, it is
something to watch as thunderstorms become more prevalent over the
next month.

.EXTENDED FORECAST DAYS 4-7...
Similar to yesterday afternoon, there isn`t much change to the
extended forecast. Models remain in good agreement with the low
in the Bering continuing to spin and gradually move east while
being rejuvenated every couple of days through next weekend.
Meanwhile, ridging is expected to persist from the Pacific to the
AlCan Border. This would continue to support the southerly flow
pattern over a good portion of the state. This would set up for
good moisture transport across the Central Interior/West Coast and
gusty winds through the Alaska Range. Models are showing the
potential for a more apparent shortwave to work its way over the
Alaska Range sometime between Monday night and Tuesday night.
There is still subtle disagreement in regards to timing and
strength. All in all, expect a similar pattern for at least the
next week with rain/snow showers across the Interior, potential
for snow in the southern Alaska Range, wind through the passes
and periods of rain/snow on the West Coast.
