Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
544 AM AKDT Fri Apr 28 2023

.ANALYSIS AND UPPER LEVELS...

A broad upper-level trough remains nearly stationary this
afternoon, its axis extending from the Chukchi Sea and Bering
Strait south to the central Aleutians. Multiple shortwaves are
rotating around the broader trough with the strongest of these
over the northern Gulf. This wave is associated with a weakening
surface low moving north toward Kayak Island and producing an
area of showers across Prince William Sound. For interior
Southcentral, temperatures are generally in the upper 30s to lower
40s for most locations with with cloud cover on the increase from
south to north.

A second upper-level wave is situated near Cape Newenham and is
producing a wide expanse of clouds and shower activity from the
Pribilofs Islands east across Southwest Alaska.

Farther west, a ridge is over the far western Bering and
Aleutians, extending south from eastern Russia. Northerly flow
between this and the low to the east continues to usher in colder
and air and gusty northerly winds for the northern half of the
Bering Sea.

&&

.MODEL DISCUSSION...

Models remain in good agreement with regard to the synoptic
features moving from the end of the work week and into the
weekend. There is still some discrepancy between models, however,
with regard to an advancing warm front and development of a
surface low over the eastern Gulf for Saturday into Sunday. The
overall trend is for a more easterly trajectory with the bulk of
precipitation east of Prince William Sound north to the Copper
River Basin. The 12z GFS and GEM, however, do bring the surface
low and precipitation shield farther west, with the western extent
of the precipitation over the western Chugach and Kenai
Mountains. The EC and NAM are farther east, with the latest NAM
run now the eastern outlier. Whatever the solution, guidance has
this feature exiting the region by early after Sunday as a
transient ridge builds in advance of the next low.

Out west, models continue to key in on development of a sub 980
mb low near the central Aleutians late Saturday into Sunday.
Again, there are discrepancies as to the timing and extent of
phasing of two upper-level waves resulting in the deepening of
this surface low resulting in differences in exact placement and
strength of the low. Nonetheless, there is higher confidence in a
high-end, gale-force low, with areas of storm-force gusts, over
the central Aleutians for the weekend.

&&

.AVIATION...

PANC...VFR visibility is expected to continue through Sunday with
possible intermittent MVFR ceilings during the day on Friday.
Turnagain Arm winds will increase through the day Friday, peaking
in the afternoon with potential 9-10 knot gust spreads, calming
down over the terminal area before midnight. Early Saturday
surface temperatures will linger briefly in the mid 30s, but
shower activity is likely to taper off before then. Accumulations
on paved surfaces are not expected.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3/Today
through Sunday night)...

Deep and moist southerly flow combined with short-waves embedded
within the flow and atmospheric instability will continue the
showery weather across Southcentral to start today off. Upslope
flow in the Susitna Valley will lead to steadier precipitation
through about midday, especially over the northern valley.
Temperatures will remain warm enough to keep precipitation falling
as rain across much of the region. The one exception is the
northern Susitna Valley/Broad Pass area which will see some light
accumulation, especially off road. Shower activity will generally
diminish through the day as the leading short-wave exits to the
Interior.

However, an atmospheric river and warm front will lift northward
across the eastern Gulf, bringing steady precipitation to the
northeast Gulf and into the Copper River Basin this afternoon
and evening. The influence of short-waves rounding a large low
in the Bering Sea and pushing into the western Gulf will help
shift the entire upper level ridge eastward a bit. As a result,
the main area of steady precipitation has shifted eastward
compared to previous forecasts. This means less precipitation
later today for eastern Prince William Sound (Cordova/valdez
areas) and the western Copper River Basin. The heaviest
precipitation now looks like it will fall well east of Cordova
northward into the far eastern Copper River Basin, including the
McCarthy area. Warm air advection looks to be enough to produce
mostly rain in the valley, with heavy snow in the mountains.
Meanwhile, the rest of Southcentral will dry out tonight. With
cool air remaining aloft, temperatures will drop back down to
freezing or below for most areas.

On Saturday, a fairly strong negatively tilted short-wave will
move into the western Gulf. This will cause the area of steady
precipitation in the Copper River basin to be pulled westward.
There is quite a bit of uncertainty in the track of the short-
wave and westward extent of precipitation. Most likely, steady
light precipitation will move into the heart of the Copper River
Basin, including Glennallen, as well as back into Cordova/Valdez.
The more westward solutions would bring precipitation to the
eastern Kenai Peninsula north-northwest to the Hatcher Pass area.
Areas further west, including the western Kenai, Anchorage, and
the Mat-Su look to remain dry with some sunshine and seasonable
temperatures on Saturday.

The upper level short-wave will ultimately kick precipitation
back eastward sometime Saturday night into Sunday, with
precipitation ending in the Copper River Basin by late Sunday.
Active weather will continue, however, as a deep low moves to the
Aleutians with a strong short-wave and frontal system headed to
the western Gulf/Kodiak Island on Sunday. Expect precipitation
and wind spreading northward across the western Gulf Sunday and
into Southcentral Sunday night. Strong winds and strong dynamical
forcing will likely produce moderate to heavy precipitation along
the coast while inland areas see significant downslope drying.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 through 3: Today
through Sunday night)...

An upper-level low centered over the central Bering this morning
will rotate several shortwaves northward across Southwest Alaska
through Saturday night. Scattered snow showers will persist as
southerly, upslope flow combines with the dynamic support from
passing shortwaves. High temperatures today are expected to be a
few degrees warmer than yesterday, which should allow for most
of these showers to transition from snow to rain during the
warmest part of the day, before turning back to snow as night
falls. Shower activity today is likely to be focused over western
portions of Bristol Bay, from Dillingham north and west, and the
Kuskokwim Delta, where upper-level support will be the best.
Showers diminish tonight as the upper shortwave exits the region
to the north and weak ridging takes its place. This trend toward
drier conditions will be aided by a shift to low-level
southeasterly flow, which will limit the moisture tap.
Temperatures will increase for Saturday with decreased cloud
cover. Then, a strengthening low entering the Bering Sea from the
North Pacific will push its front into Southwest Alaska for
Sunday. This will bring a mix of steadier rain and snow to the
region going into the beginning of next week.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 through 3: Today
through Sunday night)...

Scattered showers continue across the Bering Sea and Aleutians as
several weak troughs rotate around a closed upper-level low over
the central Bering Sea. On the west side of this low, cold air
surging southward across the western Bering will contribute to
gusty winds, snow showers, and heavy freezing spray near the ice
edge west of Saint Matthew Island. A front in the North Pacific
just south of the Aleutian Chain will nudge across the central and
eastern Aleutians today, bringing a mix of steady snow
transitioning to rain by tonight. The front weakens as it pushes
across the Alaska Peninsula Saturday morning, limiting
precipitation to the southern side of the mountains. Then, a
shortwave lifting out of the North Pacific interacts with the
upper-level low as it sinks southward Saturday night, leading to
the formation of a strengthening surface low near the eastern
Aleutians by Sunday morning. By this point, gale force winds make
their return to the Bering Sea on the west side of the low through
the central Aleutians. These gales begin to wrap around the south
side of the low as it brings widespread rain and snow to the
central and eastern Bering/Aleutians while deepening through
Sunday night.

&&

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

Starting early next week, a progressive pattern will get underway
as a strong upper low slowly moves southward across the Bering
Sea. As the upper low weakens and lifts northeastward near the
Alaska Peninsula (AKPEN), an upper ridge extends north across
western Canada and into eastern Alaska. As such, a series of low
pressure systems and fronts lifts northward across Southcentral.
Additionally, a steady influx of moisture and the approach of the
first front will support a duration of moderate to locally heavy
rain in the lower elevations and snow in the mountains. The latest
deterministic runs and ensemble means seem to favor the heaviest
precipitation along Prince William Sound and the Panhandle. Out
west, the aforementioned upper low will also support unsettled
conditions across the Bering Sea, Aleutian Chain, and Southwest
Alaska through late next week. The various systems should lead to
periods of small craft to gale force winds across portions of the
Gulf of Alaska and Bering Sea. To the far west, a separate ridge
axis begins developing across the central Bering as a system
pushes its front into the western Aleutians, bringing winds and
rain to the area.
