Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
532 AM AKDT Mon Jun 28 2021

.ANALYSIS AND UPPER LEVELS...

The Rossby Wave pattern remains highly amplified as a pronounced
blocking ridge of high pressure currently extends northward from
the western CONUS through Northwest Territory. An upper level
trough curently extends southeastward from the Kuskokwim Delta
into the North Pacific. A vertically stacked low over the western
Aleutians is moving eastward. The jetstream remains south of 50N
through 142W, then extends northeastward to over Northwest
Territory.

Closer to the surface, radar imagery shows showers moving
northward across the Gulf of Alaska into Prince William Sound and
the southern Chugach Mountains. Another area of showers is moving
northeastward across the Kuskokwim Delta.

&&

.MODEL DISCUSSION...

Guidance is in good agreement with respect to the placement and
intensity of synoptic scale features at both the surface and in
the upper levels. This leads to a high forecast confidence. The
biggest area of uncertainty is the exact location and timing of
showers, though no thunderstorms are expected.

&&

.AVIATION...
PANC...VFR conditions and light winds will persist.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3...Today
through Wednesday evening)...

An upper level disturbance along with an associated surface low
over the central Gulf of Alaska will continue moving northward
this morning. As a result, this will bring more widespread cloud
cover to much of Southcentral today with the risk for an isolated
shower or two for the Kenai Peninsula, Anchorage Bowl, and Mat-SU
Valleys. The core of this upper level energy and moisture is aimed
at the Prince William Sound area and the Copper River Basin where
scattered rain showers are expected throughout the day. Due to the
increase in cloud cover expected today, max temperatures were
brought down some to account for this as solar heating will be
limited.

Next, an upper level ridge begin to build from west to east across
Southcentral this evening through the overnight hours resulting in
gradual clearing skies from west to east. This upper level ridge
is expected to remain in place over Southcentral for Tuesday and
Wednesday bringing two days of gorgeous weather. Expect warming
temperatures (upper 60s and low 70s widespread) and drier
conditions, though, winds will remain fairly light. Areas of the
Copper River Basin and the Susitna Valley may reach 75 degrees,
especially Wednesday. As this ridge builds in it will strengthen
the pressure gradient across the Gulf, Barren Islands region and
Shelikof Strait resulting in increasing winds throughout the day
with small craft advisory level winds expected tonight through
Tuesday night.

Lastly, the Copper River Basin will be under the thermal trough on
Tuesday as an upper level wave is moving through the area. As a
result, there is the possibility for a rain shower or two to grow
into a thunderstorm that can put out a strike or two. However,
instability is rather limited, therefore, this isn't very high
confidence but support is there to leave it in the forecast.
Wednesday, almost all of Southcentral looks to have a dry day
with perhaps a few showers leftover across the Wrangells.

&&

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

An upper level low and associated trough over the Y-K Delta this
morning continues to funnel Bering moisture into Southwest Alaska,
with the southwesterly flow keeping the associated cloud cover
widespread across the area. As the low moves to near Nunivak
Island this afternoon, the combination of the moisture, forcing
from the low, and solar heating will allow another round of
showers to develop. Marginal atmospheric instability should
preclude any significant thunderstorm development.

The low will drift west away from the area on Tuesday, allowing a
ridge to build in. This should allow for significant clearing,
especially between the Alaska Range and Kuskokwim Mountains, with
the sunshine causing temperatures to warm and lowering the
afternoon minimal relative humidity values as compared to previous
days. By Wednesday, a slow moving front will stall out along the
Y-K Delta coast, which should cause cloud cover to return across
all of Southwest Alaska west of the immediate foothills of the
Alaska Range. Except along the coast, precipitation will be
minimal Tuesday and Wednesday.

&&

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

A large vertically stacked low over the Western Aleutians will
remain nearly stationary through Tuesday morning, then as a
vigorous shortwave moves in from the south, the whole low will
drift east to the Central Aleutians and stall out there through
Wednesday. The leading front will move to near the Southwest
Alaska coast on Wednesday. The upper low near the Y-K Delta will
move west across the northern Bering on Tuesday and will be
absorbed into the Aleutians low by Wednesday morning. With the
Aleutians low dominating the weather pattern across nearly the
entire Bering through the short-term, expect a long-lasting,
occasionally heavy rain, especially with the shortwave moving
into the Eastern Aleutians and eventually Alaska Peninsula Tuesday
and Tuesday night. Southeasterly gales are expected to develop
across the eastern Bering and Aleutians Tuesday afternoon through
Tuesday night.

&&

.MARINE (Days 3 through 5)...
Expect winds less than 35 kts and seas less than 20 ft for the
Day 3 through 5 period.

&&

.LONG TERM FORECAST (Days 3 through 7: Wednesday through Sunday)...

Going into the long term midweek troughing is expected over the
Bering, while a shortwave ridge is present over Southcentral AK.
This means continued active weather in the Bering and Southwest
AK, while Southcentral AK sees a break in the weather. Models are
in good agreement to start the long term so confidence is high
midweek. This pattern is slow to progress, so expect these general
conditions to last until at least Thursday. Then, general
agreement continues in that the trough shifts east and the high
lifts to the northeast, putting Southcentral back in the active
weather. This pattern generally holds in place until the weekend,
when models diverge in their solutions and thus we lose confidence
in the forecast. We do know that low pressure will generally be in
place, so we can infer active and inclement weather will continue.
