Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
508 AM AKDT Tue Apr 14 2026
.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3)...
Ridging out of the North Pacific has amplified and built across
Southwest and will push into Southcentral today, leading to a
beautiful day across the region.
Starting tomorrow, a series of shortwave troughs amid southwest
flow aloft will begin moving atop the ridge and into Southcentral.
The first front and associated precipitation reaches Kodiak
Island Tuesday night before then spreading across the Kenai
Peninsula and the rest of the area during the day on Wednesday.
Lingering cold air will keep most precipitation as snow during the
morning hours, but expect lingering precipitation, mainly in the
Susitna Valley, to mix with rain in the afternoon. The Copper
Valley will also get snow in the afternoon, so expect a quick drop
in temperatures in the afternoon for areas under snow showers.
Amounts will be very light with most locations outside of the
mountains not expecting more than a few hundredths to one tenth
of an inch liquid equivalent or trace to an inch of snow.
Precipitation looks to diminish Wednesday night as ridging builds in
wake of this system, but another front, tied a more potent low in
the eastern Bering, shifts into Southcentral again on Thursday
and Thursday night. There remains some timing differences with
various model runs, but Kodiak Island looks to get the next wave
of precip sometime Thursday morning before the rest of
Southcentral gets it later into the day and into the overnight
period. Snow levels will be similar to the previous day`s system,
though perhaps a few hundred feet higher initially due to the
timing. Locations at elevation should remain most/all snow with
this next wave.
&&
.SHORT TERM FORECAST SOUTHWEST ALASKA/BERING SEA/ALEUTIANS (Days
1 through 3: Today through Friday morning)...
A front is currently passing through the East Bering. This front
is bringing a band of precipitation along as it pushes eastward.
Precipitation will initially be snowfall, but due to warm air
advection snow will transition to a rain/snow mix or rain at the
back end of the front. Also behind the front over the Bering, low
stratus/fog is possible. As the front pushes inland by this
afternoon, snowfall will spread out across the Southwest Mainland.
Due to a cooler airmass in the mainland, precipitation will
remain mostly snowfall until Wednesday afternoon. Snow amounts
range from 1 to 3 inches before precipitation chances dwindle and
snow transitions to a mix of rain and snow on Wednesday.
Additional shortwaves will drift in behind the front, allowing for
mixed precipitation in the Bering and the Southwest Mainland
through Friday morning. Wind speeds will remain elevated, but
remain sub-small craft through Thursday night. Overnight snowfall
will allow for an additional 0.5 to 1 inch of snowfall across the
mainland Thursday night, but this will likely melt by the day as
temperatures warm above freezing.
Meanwhile, a ridge will set up over the Bering by Friday morning,
which will diminish precipitation chances and decrease wind
speeds. However, a strong North Pacific Low looks to rise into the
western Aleutians late Friday morning, which could bring strong
gusty winds and moderate to heavy precipitation.

&&
.LONG TERM FORECAST (Days 4 through 7: Thursday through
Sunday)...
An active pattern continues for mid-April with multiple systems
bringing precipitation and cloud cover to the region. Broad upper-
level troughing across the western Bering and coastal mainland
will be in place to begin the period, placing the Aleutians and
much of Southern Alaska in active quasi- southwest flow with
embedded shortwaves. Kicking off the period on Thursday,
precipitation will overspread much of Southcentral AK amid
southwest flow.
On Friday afternoon, the front of a strong North Pacific low
lifts across the Bering Sea, bringing mostly rain to the Aleutian
Islands and widespread gales to the southern Bering. As the center
of the system crosses into the Bering, winds weaken before
reaching the mainland, and precipitation evolves into a rain/snow
mix to all snow for the Alaska Peninsula and Southwest Coast by
Sunday afternoon.
While uncertainty remains high concerning details beyond Friday,
the upper- level low will remain in place across mainland Alaska,
and unsettled weather will continue for Southwest and Southcentral
through the start of next week. Temperatures will generally be
near average.

Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK
540 AM AKDT Tue Apr 14 2026
.SYNOPSIS...
Majority of the snowfall has tapered off across most of the
Interior. However, lingering moisture may allow for isolated
chances throughout the day. A colder airmass will continue to
build up over the North Slope as an upper level low moves south
from the Arctic. Another front will begin to move over the YK-
Delta from the Bering Sea by this afternoon. Most of the
precipitation, today, will be snow. Precipitation types will
become more diurnally driven tomorrow, and for the rest of the
week, as warmer air moves in from the SW. Light showers will
persist along this front as it eventually sets up in a E-W
orientation on a line from the souther Yukon Flats to the southern
Seward Peninsula. Another, slightly stronger, surface low will
follow behind this front and set up just off the coast of the YK-
Delta. This will help set up a northeasterly gradient across the
West Coast which will result in gusty winds through the Bering
Strait and NW Arctic Coast through the end of the week.
&&
.KEY WEATHER MESSAGES...
Central and Eastern Interior...
- Cooler temperatures remain through the end of the week with
highs in the 30s and lows in the 20s for most areas.
- Scattered snow showers may continue to linger across the Central
Interior and higher elevations across the Eastern Interior
today. Little to no accumulation is expected.
- An E-W oriented front sets up, from Eilson to Nome, by Wednesday
afternoon. This will bring another round of widespread rain/snow
showers across the Interior. Precipitation types will be
dynamically driven with a rain/snow mix during the day, mostly
rain at lower elevations, and mostly snow during the overnight
hours.
- Total snowfall accumulations through the end of the week from
this front are expected to be between 1" and 3".
West Coast and Western Interior...
- Breezy northeasterly winds will continue throughout the day
today, with the strongest winds from the Bering Strait to St.
Lawrence Island. Gusts are expected to be between 25 and 35
mph.
- Another round of precipitation approaches the West Coast today
bringing periods of light rain, snow, and mixed precipitation to
portions of the West Coast and Western Interior through the end
of the week. Precipitation will be most consistent for areas
south of the Bering Strait along the West Coast and south of
Huslia across the Western Interior.
- Precipitation will be mostly snow today and become more
diurnally driven by Wednesday afternoon with a rain/snow mix
during the day, mostly rain at lower elevations, and mostly
snow during the overnight hours.
- Temperatures cool throughout the week with highs in the 20s and
overnight lows in the teens to single digits above zero.
North Slope and Brooks Range..
- Scattered snow showers linger across the Brooks Range into next
week, especially along southern facing slopes. Travel through
Anaktuvuk Pass or Atigun Pass may be slightly impacted by light
snowfall and breezy northerly winds.
- Periods of gusty winds return to the northwest Arctic Coast
today through the end of the week. Gusts as high as 45 mph
possible between Point Hope and Point Lay. Periods of blowing
snow may reduce visibility and make travel difficult. A Winter
Weather Advisory has been issued.
- Temperatures continue to rapidly cool and are expected to
remain cool through the end of the week. Highs fall to the
single digits above zero while overnight lows reach as cold as
the teens below zero.
&&
.FORECAST ANALYSIS AND DISCUSSION...
For Tuesday through Friday.
Little to no change has been made to the overall forecast as
persistence continues to hold strong. Satellite images from this
morning shows a low, previously in the northern Gulf of Alaska,
weakening and shifting SE down the Alaska Panhandle. Over the
Bering, a ridge continues to build. behind this ridge is a defined
front that is expected to move over the state by the start of the
afternoon. With the building ridge in the Bering, this has allowed
for quieter weather over the West Coast, however some low clouds
and scattered patches of fog continue to linger from the previous
system. Over the Arctic, a distinctive trough is beginning to push
farther south toward the northern Arctic Coast, providing most of
the north slope with a shallow cloud deck, scattered snow showers,
and patchy fog.
The short term portion of the forecast will be largely driven by
the front in the Bering and the trough digging south over the
Arctic. Depending on how fast the trough is able to move south,
will determine how far north the front will be able to push before
stalling. Latest guidance shows the front`s associated shortwave
moving W/NW over the YK-Delta by this afternoon. While over the
Bering, an E-W oriented 522 decameter low sets up over the North
Slope. As the front moves over the YK-Delta, the front will get
stretch zonally across the central portion of the state and
stalling along a line from the southern Yukon Flats to the
southern Seward Peninsula. Most of the precipitation with this
system will start off as snow. However, the associated shortwave
moving across the state will result in westerly/southwesterly flow
aloft. This will allow for slightly warmer temperatures to move
in from the tropics. By the time Wednesday rolls around,
precipitation types will become diurnally driven with a rain/snow
mix during the day, mostly rain at lower elevations, and mostly
snow during the overnight hours. Precipitation chances will be
widespread across most of the southern half of the state by
Wednesday and lasting through the end of the week.
A surface low will be slowing pushing east behind this front as it
sets up across the central portion of the state. Meanwhile, a
surface high will already have been set up in the northern
Chukchi. This will allow for the gradient to tighten as the low
moves toward the YK-Delta, resulting in gusty NE winds across a
majority of the West Coast. The strongest winds are expected over
the NW Arctic Coast, with slightly weaker winds through the Bering
Strait to St. Lawrence Island. Winds will begin to peak by this
evening, allowing for blowing snow potential to return over the
Lisburne Peninsula. With the Arctic Trough moving over the North
Slope, this will allow for temperatures to remain on the cooler
side, allowing for better chances for blowing snow.
The short term portion of the forecast comes to an end with the
surface low continuing to progress inland over the YK-Delta. This
will set up the, all to familiar, "troughiness" pattern across a
good portion of the state. A more pronounce upper level trough
will also begin to move south from the Arctic, which may continue
to support the troughiness pattern and colder temperatures to
continue to the start of the weekend.
&&
.EXTENDED FORECAST DAYS 4-7...
For late Friday through next Tuesday.
Compared to yesterday`s discussion, a decent bit of model
disagreement creeps in early in the extended forecast period. All
of the global models show a pronounced trough to form over the
state, with a ridge building over the Bering by the start of the
weekend. They also show the potential for another upper level low
to move north from the western Aleutians by the mid weekend.
Beyond this, model agreement begins to decline.
The GFS and Canadian are in agreement in showing a ridge becoming
more pronounced and extending farther north into the Chukchi. This
would push the upper level trough, that was previously over the
Arctic Plains, east of the Al-Can boarder. Meanwhile, the ECMWF
does not have this strong more pronounced ridge building in and
having the low from the western Aleutians moving over Bristol
Bay. It also shows an additional shortwave working its way south
along the West Coast and getting wrapped into this low as it
continues to shift east. The GFS and Canadian show a system moving
along a similar trajectory, although this is from a shortwave
that gets wrapped into the broad trough, over the state, from the
low over the western Aleutians. The EC solution shows a more
widespread area of precipitation across the state as it pushes
east, compared to the GFS and the Canadian. By the time the end of
the weekend rolls around, all of the models are showing northerly
flow setting up over the West Coast. This will have to continue
to be watched as this may bring another round of seasonably colder
temperatures back across the state by the mid-week.

Southeast Alaska Forecast Discussion
National Weather Service Juneau AK
530 AM AKDT Tue Apr 14 2026
.SYNOPSIS...
Key Messages:
- Tuesday is expected to see a clearing from north to south, with
increased chances of sun and warmer temperatures.
- Showers return late on Wednesday and into Thursday.
&&
.SHORT TERM.../ Through Tuesday night / Low over the south central
panhandle through Wednesday, and this had been keeping most of
showers limited to the southern panhandle. There are a few
clusters of showers, one is moving into western Prince of Wales
island about 5 am and there is a second cluster out over the
southeast gulf, and that will probably make land fall between 8
and 11 am in the same are. Some these could be stronger showers,
with some locally gust winds, and possibly sleet.
As the low weakens and pulls to the southeast, look for clearing
for the northern portion of the panhandle through the afternoon
and evening. The only issue for the northern panhandle is a
trough between Yakutat and Glacier Bay that has clouds streaming
Southwest out to the gulf. Closer to the surface the trough
positions may lead to some upslope on the Canadian side of the
border but could spread some light snow into the northern Lynn
Canal area Tuesday morning.
The moving ridge over the gulf nudges some clearing/drying
conditions for Wednesday.
.LONG TERM...The low impacting the southern panhandle Tuesday will
continue to dip south into Wednesday, allowing for skies over the
rest of the panhandle to clear out. A broad upper level ridge
develops, with the associated surface level ridging positioned to
continue onshore flow into the panhandle. Mid level moisture looks
to move into the northern panhandle with a shortwave trough on
Wednesday night, allowing for light snow in Yakutat and parts of
the far northern panhandle Thursday morning. Snow is not really
expected to stick for these locations as temperatures remain
around freezing, though higher elevation areas and the Klondike
and Haines Highways may see up to an inch. This precipitation will
be a mix or all rain for the rest of the northern and central
panhandle Wednesday, moving into parts of the southern panhandle
through Wednesday night into Thursday. Showers are expected to
continue until Thursday night, when a more organized front moves
into the panhandle from northwest to southeast. This will bring
widespread precipitation to the panhandle Friday into Saturday,
though QPF remains on the lower side. Again, Yakutat and the
northern highways may see snow with this front, though daytime
temperatures should only allow for minimal, if any, accumulation.
Precipitation is expected to taper down through Saturday, though
it may not completely stop until Sunday. The only real wind issue
is expected near the typical hot spots from Thursday into Friday
as the front moves inland, with Lynn Canal, southern Stephens
Passage near Five Finger Lighthouse, and around Point Couverden
potentially seeing small craft advisories through this period.
&&
.AVIATION...Showers have largely come to an end across a majority
of the panhandle Tuesday morning with clearing north of Sitka.
Some patchy fog may develop but should quickly dissipate with
daytime heating. Some isolated showers remain possible over the
next few hours primarily for the southern panhandle, but overall
improving trend throughout the day Tuesday.
&&
.MARINE...
Outside Waters: A general trough extends form the southern panhandle
towards Prince William Sound Tuesday as a low over the southern
panhandle falls apart. Long, wide fetches with consistent westerly
winds look to build seas from 5 ft up to 10-13 ft at 9 to 10 seconds
before diminishing slowly Tuesday night.
Inside Waters: A low positioned between Sumner Strait and
Frederick Sounds this morning will see this low weaken and slide
SE through day falling apart by afternoon. Winds for the northern
channels in the 10 to 15 kt range. The southern panhandle winds
look to lighter today, although wider portions of Clarence Strait
may see a more Southwest direction for the wind.
