Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK
549 AM AKDT Wed May 20 2026

.SYNOPSIS...
Broad troughiness continues over the Bering. This is allowing for
daily chances for isolated showers across much of the West Coast
and the Interior. High pressure holds strong over the Arctic which
will keep the cooler temperatures and low ceilings over the North
Slope over the next couple of days. Another low will move inland
from the northern Gulf of Alaksa, bringing a line of showers
across the Interior throughout the day, today, and into tomorrow.
Another, more pronounced low will move along the Aleutians,
setting up around Bristol Bay sometime Thursday morning. An
abundant amount of energy is associated with this low and will
wrap a series of shortwaves into the Central Interior and West
Coast over the next couple of days. In addition, southerly flow
will be set up over the Alaska Range as these shortwaves move
north, setting up the potential for another round of gusty winds
through the Isabel and Windy Pass on Thursday. The upper-level
trough will slowly elongate eastward through the end of the week
which will slightly increase the chances for isolated
thunderstorms through the start of the weekend.

&&

.KEY WEATHER MESSAGES...

Central and Eastern Interior...
- An increased chance of precipitation today as a system moves
  north across the Interior. This will set up daily chances for
  isolated showers and a non-zero chance for a thunderstorm or
  two.
	- Chances for thunderstorms become more scattered across the
   Central Interior by Friday afternoon.

- Seasonably warm temperatures are expected to continue across
  the Interior through much of the week.

West Coast and Western Interior...
- Gusty S-SE winds are expected to continue across the West Coast
  through with an upper-level shortwave passage. Thunderstorm
  chances continue for portions of the Western Interior.

- Showery conditions are expected along the Lower Yukon and Yukon
  Delta regions throughout the week. Light showers expected today
  with heavier showers possible on Thursday. These showers will
  be mostly rain, especially nearer the Western Interior, but some
  periods of snow and light wintry mix are possible near St.
  Lawrence Island and the Bering Strait Coast.

North Slope and Brooks Range..
- Breezy northeasterly winds along the Western North Slope weaken
  slightly and shift more easterly. E to ENE winds 15 to 25 mph
  are expected across the Arctic Coast through the rest of the day.

- Diurnal showers along the southern portion of the Brooks Range
  are expected to continue through the week. Little to no
  precipitation is expected for the North Slope

- Chilly temperatures persist with highs in the 20s and lows in
  the teens along the North Slope. A gradient of temperatures
  across the Brooks Range with highs in the 50s to near 60 along
  the southern slopes and low 40s for the northern slopes.

- Low clouds and areas of fog persist across the Arctic Coast and
  will likely remain through much of the week, especially along
  the Eastern Arctic Coast.

&&

.FORECAST ANALYSIS AND DISCUSSION...
Isolated showers continue across portions of the Central Interior
and West Coast as the remnants of a shortwave move NW over the
Norton Sound. Another low continues to work its way into the
northern portion of the Gulf of Alaksa. Models continue to show
agreement in this low setting up between the 150 and 140 degree
longitude line, which will be a good setup for wrap around
precipitation into the Interior. Meanwhile, a more pronounced low
will be work its way up the Aleutians, entering Bristol Bay
Thursday morning. Ahead of this low, a warm front will swing
across the YK-Delta late tonight into early Thursday morning.
However, some isolated showers may continue to linger across the
West Coast throughout the day, today. Cold air will continue to be
advected from the north across the Bering, which will allow for
mixed precipitation chances to continue St. Lawrence Island and
the Bering Strait.

This new low over Bristol Bay will eventually take over as the
main driver for the broad troughiness across much of the state.
With this, a series of shortwave will wrap around this low which
will allow daily chances for scattered showers and isolated
thunderstorms to continue across much of the state through the end
of the week. A more pronounced line of energy will begin to work
its way north, by Thursday, as it stretches from the YK-Delta to
the Eastern Interior. This will help tighten the gradient and
allow for another round of gap winds through the Alaska Range on
Thursday. The main bulk of the energy will work its way into the
Kuskokwim valley on Friday, setting up the next chance for
scattered, afternoon thunderstorms. The best chance for storms,
Friday, will be across the Central and Western Interior.

Looking over the North Slope, high pressure continues to linger
off the northern Arctic Coast. Cooler temperatures, breezy east
winds, and low cloud ceilings are expected to continue as the
overall pattern is not expected to change much over the next few
days.

As the end of the short-term period rolls in, models are showing
the potential for a shortwave to peel away from the main low and
work its way east across the Gulf. Doing this will help stretch
out the trough farther east, potentially setting up easterly flow
across portions of the Interior by the start of the weekend. A set
up like this would be favorable for isolated to scattered
thunderstorms across the Interior throughout the weekend.

&&

.FIRE WEATHER...
The overall pattern remains mostly the same through much of the week
with a low in the Bering Sea and ridging over Western Canada. This
pattern will continue to support broad southerly flow across the
region. Downsloping effects will work to keep most of the Central
and Eastern Interior dry and warm with a few afternoon rain showers
possible tomorrow. Increased chances for precipitation return this
weekend as an influx of moisture is brought into the Interior.
Accumulations should remain light with localized higher amounts
expected in southwest Alaska, the Brooks Range, and where
thunderstorms are present. Although chances are low, a non-zero
chance for lightning is possible Friday afternoon through Sunday
afternoon across portions of the Interior, Brooks Range, and Yukon
Flats. Expect high temperatures in the 60s and lows in the 40s
through the week, with min RH values ranging between 20 to 30% in
the Central and Eastern Interior and 30 to 40% in the Western
Interior.

The greatest fire concern this week will be near Delta Junction as
strong southerly gap winds strengthen again on Thursday due to a
tightening pressure gradient over the Alaska Range. Expect sustained
winds 25 to 35 mph gusting as high as 60 mph possible. Winds will
gradually weaken throughout the day Friday before subsiding by
Saturday morning. Although min RH values are expected to be a bit
higher on Thursday (around 30%), critical fire weather conditions
may still develop in Delta Junction Thursday afternoon. The biggest
limiting factor for this will be temperatures and whether or not
highs in the mid to upper 50s can dry out the atmosphere enough to
reach an min RH value of 25% or lower during the afternoon.
Therefore, we will continue to monitor the situation throughout the
day tomorrow.

.HYDROLOGY...

Yukon River: The breakup front on the Yukon has passed Russian
Mission. As of Monday evening, an ice jam 10 miles downstream of
Russian Mission remains in place mostly unchanged. A Flood Warning
remains in effect. Extensive flooding of the lower portion of Holy
Cross community was occurring Tuesday, including the Holy Cross
runway. Water remains high on the Yukon upriver from the breakup
front due to snowmelt and the Yuki Ice Jam release. Water has
inundated the road to the airport at both Grayling and Holy Cross.
Flood warnings remain in effect.

The ice jam located downriver of Russian Mission is made up of
about 3 miles of large intact ice sheets extending from Roosevelt
Island to Seven Mile. River Watch overflew the ice jam at noon
Tuesday and again at 5pm and saw no change. About 60 miles of
chunk and pan ice extend from the head of the jam upriver past
Holy Cross. The most extensive flooding is occurring at Holy Cross
and in the lowlands between Holy Cross and Anvik. Most large Yukon
River ice jams during recent years decay, erode and fail within a
few days. The current jam at Russian Mission is going on day 3.

Chena: The Chena River continues to respond to warmer temperatures
with higher elevation snowmelt leading to rivers running higher than
normal, but likely remaining below action stage.

Additional Information: Visit www.weather.gov/aprfc for the latest
hydro information.

Please report observed flooding to local emergency services, law
enforcement, or to the National Weather Service when you can do so
safely..

.EXTENDED FORECAST DAYS 4-7...
High pressure in the Arctic will allow for persistent easterly winds
to blow along the Arctic coast and northerly winds along the West
Coast through the weekend. Scattered showers will be possible across
most of Northern Alaska from Saturday into the weekend, with
isolated thunderstorms possible among these showers in the Interior,
especially in western areas. Generally warm conditions will persist
throughout the period south of the Brooks Range, with highs in the
50s and 60s. The West Coast will likely see highs in the 30s and
40s, with 20s and 30s on the North Slope. Additional showers will be
possible across Northern Alaska early next week ahead of another
potential system in southwestern Alaska.

Coastal Hazard Potential Days 3 and 4...None
