Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
530 PM AKST Sun Jan 31 2021

.ANALYSIS AND UPPER LEVELS...

An eastward moving short wave tracking across Southcentral this
morning brought light snow to the Copper River Basin and North
Gulf Coast. Gusty outflow winds continued through Thompson Pass.
Subsidence under the upper ridge aided the development of stratus
and fog from the Knik Valley and the lower Matanuska Valley to
across Knik Arm and Anchorage Bowl this morning. These conditions
have since improved.

Out west, except for some clouds along the Delta Coast, fair skies
and cold temperatures were observed over the Southwest Mainland.
Gusty winds over the Delta and locally gusty winds across
interior Bristol Bay produced wind chills in the -20s. The broad
frontal system over the Central Aleutians/Bering Sea is moving
ever so slowly as the upper ridge to the east slows its eastward
progression. Broad and gusty southerly flow over the region
continued cloudy and warm conditions with areas of rain (mainly
Aleutians/Bering).

&&

.MODEL DISCUSSION...

Models still struggle with the progression of the frontal system
toward western Alaska. The timing differences stem from the
development of a surface wave along the front and its movement.
Positioning and timing of this wave/front will significantly
affect potential impacts to Coastal Southwest Alaska. A slower
frontal progression will likely be the best as the upper ridge
and cold air over the Mainland will be difficult to displace.
Models are in generally good agreement across Southcentral and the
Gulf. Outflow and gap winds will be the main concerns and will be
largely addressed with targeted edits and high res models.

&&

.AVIATION...

PANC...VFR conditions will prevail. North winds will increase and
become rather gusty Monday morning.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3/Tonight
through Wednesday)...

Stronger wind gradients and colder temperatures dipping to -20
to -30 degrees Celsius in the mid-levels north and east of the
Matanuska Valley through Copper River Basin and along the coast of
Prince William Sound will generate headlines for the next couple
days. A highly anticipated strong polar low and its associated
upper level trough will continue to move southward tonight
through Monday night, which will cause falling air temperatures
to expand to just east of the Anchorage Bowl and Susitna Valley.
A Wind Chill Advisory was issued for both Thompson Pass and Broad
Pass effective tonight through at least Tuesday afternoon to
mirror the onset of the strong polar low and falling temperatures.
The models are still consistent about the track of the polar low
including the area of low pressure over the northern Gulf this
evening through Monday. A strong off-shore flow pattern will
persist with much higher gusts near the passes and gaps tonight
through at least Monday night.

An upper level high from Southwest Alaska will not move past its
current spot due to significant energy associated with the polar
low. Yet, very strong winds on the leading edge of the high will
continue to reinforce the northerly motion of the polar low into
Monday evening. A High Wind Warning was issued for Thompson Pass
to reflect this situation. Overall, very strong gusts and really
cold temperatures in the single digits to below zero will spread
across the area over the next couple days.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2: Sunday to
Tue morning)...

A cold air mass remains in place over much of the Southwest this
evening, although temperatures are beginning to come up closer to
0 F as winds begin to pick up slightly and as upper level clouds
slow radiational cooling. These clouds are associated with the
outer reaches of a strong front over the central Bering, and
offshore easterly winds will increase through Monday as the front
approaches from the west. While temperatures across the Southwest
should continue to slowly warm over the next couple days, expect
bitterly cold wind chills to stay in the -20 to -30 F range over
much of the Kuskokwim Delta area due to the increasing winds.

As the front reaches the Southwest coast, snow will overspread the
area from southwest to northeast. A warm nose aloft may lead to a
period of wintry mix near the Kuskokwim Delta and Bristol Bay,
including sleet and perhaps a short period of freezing rain
along the immediate Bering coastline. Blowing snow is likely with
the snow as the front moves ashore on Tuesday, especially for areas
north and west of Bethel, including Hooper Bay down to Toksook
Bay. The heaviest snowfall totals will be near the same region of
the western Kuskokwim Delta, with storm totals of 6 to 9 inches
of accumulation near the coast and lower amounts in the 2 to 6
inch range farther southeast near Bristol Bay. Models have
struggled with the timing and evolution with this front up to this
point, but are coming into better agreement this afternoon. Thus,
have increasing forecast confidence for impactful blowing and
falling snow over much of the Y-K Delta. Stay tuned for further
updates and possible winter weather headlines for the Tuesday snow
and blowing snow potential.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2: Sunday to
Tue morning)...

A strong but gradually weakening gale force front will continue
marching gradually east into the eastern Bering through Tuesday.
Rain and gusty winds ahead of the front will slowly decrease as
the front progresses east until the front moves inland over
Southwest Alaska on Tuesday. Colder air and somewhat clearer skies
will push in behind the front with widely scattered snow and rain
showers persisting within an expanse of cold westerly flow. The
front's parent low over the far western Bering will continue to
lift slowly north, with southerly small craft winds possible near
the low across the far western Bering/Aleutians through Tuesday
morning.

&&

.MARINE (Days 3 through 5: Wednesday through Friday)...

Gulf of Alaska: Generally light winds and low seas will persist on
Wednesday. However, there is some uncertainty as to whether a
surface low will bring a front to the North Gulf Coast by
Wednesday afternoon through Thursday. By Friday morning, there is
higher confidence that a front, with the potential for gale force
winds, will enter the southwest Gulf and spread across the Gulf
through late Friday. The biggest uncertainty is the track of the
associated low.

Bering Sea: A gale force front on Wednesday, with the potential
for storm force gusts over the central Bering and Aleutians, will
continue to track eastward and weaken over the eastern Bering
late Thursday. A strong North Pacific low will lift northward
towards the eastern Aleutians on Friday morning, but there is
still much uncertainty with the track of this low, the timing of
the low, and the strength. Models agree that this system will have
gale force winds accompanying it on Friday, but are struggling on
whether the system will track into the eastern Bering as far
north as the Pribilofs or whether the low center will remain south
of the Aleutian Chain.

&&

.LONG TERM FORECAST (Days 4 through 7: Thursday through Sunday)...

The long term starts with high pressure over mainland AK with a
ridge extending into Southwest AK. The remnants of weak low
pressure exists along the Gulf of AK coast and low pressure exists
in the western Bering as well. Weather stays generally quiet for
the next day or so, until a moderately strong low pressure system
moves directly north out of the North Pacific on Friday. It then
progresses north through the Eastern Aleutians and Alaska
Peninsula. Up until this point, models are in agreement with the
pattern and the movement and strength of this low. So, high
confidence that we will see low pressure impacts the Eastern
Aleutians and AKPEN on Friday.

Past this point, models diverge on the track of the low. The GFS
takes a more westerly track and brings the low through the Eastern
Bering and sends a front and secondary low through the Northern
Gulf of AK and into the Southcentral Coast over the weekend. The
ECMWF take more of an easterly track and sends the low into SW AK
and then into Western Mainland AK. The ECMWF also spins up a front
along the Gulf coast, but a much weaker one. What we can glean
from this is high confidence that Southwest AK will see inclement
weather this weekend, as both models have the region being
impacted one way or another. We have lower confidence in the track
of the low and the strength of the front along the Gulf coast.
So, low confidence in the track of the low, but since both models
have some kind of front along the Gulf coast, we can have moderate
confidence there will be weather there this weekend. Weather for
interior Southcentral will remain quiet to start and we will need
to see how the forecast shapes up for the incoming front next
weekend before we make decisions there.
