Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
501 PM AKST Sun Dec 22 2024

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

Precipitation remains largely downsloped out this afternoon, with
some breaks of low elevation sunshine being observed at some
inland locations, including Anchorage. The pattern remains the
same as the past several days, with low pressure tracking from the
southern Gulf toward Kodiak Island and a series of shortwave
troughs lifting north across Southcentral Alaska. Freezing rain,
or meteorological rain with below-freezing surface temperatures,
will continue to be a possibility at times for many locations
across Southcentral through Monday night. Snow will be limited to
elevations above 2000-3000 ft, with the exception of the potential
for an inch or so of snow accumulation in the western Copper River
Basin near Eureka and Tahneta Pass this evening as cold
northeasterly flow leads to some upslope precipitation for parts
of the Copper River Basin. Greater snow accumulations (up to
around 4 inches) are likely along the Richardson Highway south of
Tonsina, though this will be mixed with up to a tenth of an inch
of freezing rain. Along the Edgerton Highway, sleet is expected to
mix with snow as warm air is in place across the southern Copper
Basin while a deep layer of cold air remains near the surface.

Monday morning, the main axis of the upper level trough shifts
north across Southcentral, bringing the next significant chance of
precipitation spreading inland past the coastal mountains. The
Copper River Valley can be expected to get in on the action as it
looks like a small amount of snow (less than one inch) will be
able to accumulate in the valley. However, there is significant
uncertainty with what this will do for portions of the southern
Copper Basin, where some model guidance suggests the push of
southeasterly winds, which are expected to reach the surface,
bring temperatures above freezing for some time. More likely,
though, the depth of antecedent cold air will prevent temperatures
from warming that significantly and instead peak somewhere in the
20s. A shallowing of the cold air near the surface will thus make
freezing rain a possibility during this round of precipitation on
Monday. For the Cook Inlet region, the Anchorage Bowl and the
southern Susitna Valley are the most likely focus for freezing
rain potential. Though this would likely be only a brief period
for Anchorage, there is a greater chance of accumulating
precipitation in the Susitna Valley, particularly south of Willow,
however not all models are biting off on that solution just yet.
For the Kenai Peninsula, warmer temperatures will keep any
precipitation rain, and the Matanuska Valley looks to stay mostly
dry.

The southerly push of warmer air also coincides with a weakening
down-inlet pressure gradient, which will allow for a straightening
of the Turnagain Arm wind, likely impinging on the south side of
Anchorage for a time on Monday afternoon, which could bring
temperatures locally close to 40. However, cooler air begins to
move in aloft on Monday night, and though surface temperatures may
remain above freezing for a time precipitation changes over to all
rain or snow, and freezing rain becomes less of a concern across
Southcentral. Tuesday and Wednesday, shortwaves continue to lift
across the area, though downsloping remains, so expect continued
wet conditions along the coast and periods of very light
rain/snow inland.

.SHORT TERM FORECAST SOUTHWEST ALASKA/BERING SEA/ALEUTIANS
(Days 1 through 3: Through Wednesday)...

Additional precipitation will still be possible across
the greater Bristol Bay region, tonight into Monday. A warm layer
of air between freezing layers aloft and at the surface, will
provide a favorable setup for freezing rain, with the best chance
for up to a tenth of an inch of freezing rain between Koliganek
and Dillingham. A Winter Weather Advisory has been issued through
Monday morning due to this potential. The entire column will cool
below freezing by Monday afternoon, allowing any lingering
pockets of freezing rain to switch over to snow.

The low which brought freezing rain and mixed rain/snow to
Southwest Alaska over the previous several days has weakened
north of Cold Bay. This will consolidate Sunday night over Kodiak
Island with a low in the northern Gulf. Meanwhile, the front of a
strong North Pacific system will sweep eastward across the the
Aleutian Island chain Monday. Storm force winds will initially be
possible as the front reaches the Western Aleutians, but the
front should quickly weaken to gale force before it lifts
northeast into the southern Bering Monday afternoon. Models
continue to struggle to resolve rapid formation and dissipation of
multiple triple-point lows along this front, and there may be
changes to the wind and precipitation forecast for Monday into
Tuesday due to this inherent uncertainty for the location and
development of these smaller lows. There is a general consensus
for the main low to eventually shift or redevelop towards the
AKPen by Tuesday afternoon. Strong northeast winds will also
continue to spread across the Bering Sea as a colder air mass
begins to spread south from the Arctic Tuesday night into
Wednesday.

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

A broad upper level trough stretches from the Arctic all the way
down to the North Pacific and northern Gulf on Wednesday, with
several surface lows forming in the pattern. The trough axis will
shift eastward into the weekend, with the main cluster of surface
lows taking shape in the central Gulf. A ridge will start moving
into the western Bering late Thursday before moving over mainland
Alaska by late Saturday. Behind the ridge will be a second upper
level trough moving in from Kamchatka over the western Aleutians
and Bering by Saturday. The Bering ridge and a ridge forming over
Southeast Alaska will interact over the interior on Sunday,
resulting in a strong ridging pattern over most of mainland Alaska
by the end of the extended forecast period.

While the troughing pattern persists through Saturday, the series
of lows and fronts forming near the Alaska Peninsula, Eastern
Aleutians, and Kodiak will help provide repeated rounds of heavy
rains along the coastline until the ridge builds in. Bitter cold
air will begin to fill in over interior Southwest Saturday before
spreading into portions of Southcentral on Sunday, continuing
beyond the end of the extended forecast period.

&&.AVIATION...

PANC...VFR conditions with light northerly winds will persist
through Monday morning. There remains a slight chance this evening
of some very light sprinkles of rain over the terminal. The next
shortwave and surface trough will move across the Anchorage Bowl
early Monday morning. These will bring a better chance for
precipitation to the terminal early Monday morning through midday.
With temperatures hovering near freezing, the precipitation may
fall as a period of freezing rain. Any ice accumulation is
expected to be light, nothing more than a glaze of ice.

The upper-level wave will also bing an increase in southeasterly
winds at mountaintop level and through Turnagain Arm. This will
likely result in a period of LLWS Monday morning. By midday, there
is a chance that the southeasterly Turnagain Arm wind lifts into
west Anchorage and across the terminal. Any southeasterly wind
over the terminal will likely become northerly again by Monday
evening.
