Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
533 AM AKDT Thu Aug 12 2021

.ANALYSIS AND UPPER LEVELS...

A persistent amplified pattern remains in place with an elongated
longwave trough and vertically stacked cold low over the Beaufort
Sea with the trough axis extending from the Arctic Ocean to the
North Pacific. At the base of the trough, a series of upper level
waves embedded in the southwest flow aloft is ejecting across the
Bering and into the Alaska mainland. The jet stream extends from
the western Pacific to the south of the Aleutian Chain into the
Gulf of Alaska, with a 100+ kt cyclonically curved jet streak in
the left exit region. Meanwhile, a ridge of high pressure aloft
extends from the Pacific Northwest to the southeastern Gulf. Based
on the CIMSS MIMIC imagery, a steady stream of tropical moisture
or atmospheric river of 1-2" of precipitable water extends
northeastward to southern Alaska. This Fall-like weather regime
has contributed to a very active storm track across the Pacific
and into the Gulf with appreciable amount of rainfall over
Southcentral this past week. This is also demonstrated on the 12Z
Anchorage upper air sounding with a moist profile and total PW
value of 0.92," with variable to low-level southeasterly winds and
increasing, southwesterly winds aloft.

A surface low and associated frontal boundary is moving north of
Cook Inlet, bringing steady rain from the western Kenai Peninsula
into Anchorage Bowl and the Mat-Su Valleys, and moderate to heavy
rain in eastern Prince William Sound. Out west, an upper level
wave coupled with a moist boundary layer is providing some rain
showers across the Y-K Delta, Bristol Bay, and the Lower Kuskokwim
Valley. The latest ASCAT passes shows small craft advisory level
winds over the marine areas in the central Gulf. The Nighttime
Microphysics (RGB) this morning shows areas of marine stratus from
the Bering to the Southwest as well as Southcentral coast, and a
mix clouds over the Copper River Basin.

&&

.MODEL DISCUSSION...

The latest models are in consolidated agreement with the synoptic
scale features and on track for an active and wet pattern in the
short term. As the trough axis moves in the Alaska mainland, the
bulk of moisture and precipitation associated with the atmospheric
river will be concentrated over eastern Prince William Sound, the
Copper River Basin, and Southeast Alaska over the next couple of
days. The 06Z solutions are also keying on a North Pacific low
moving towards the western Aleutians late this weekend, but
deviate on the exact track and position. Subsequent model runs
will be needed for better consistency as this will be worth
monitoring for any potential impacts with regards to rain and wind
along the Aleutian Chain.

&&

.AVIATION...
PANC... Rain with northerly winds will continue this morning with
ceiling and visibility potentially reducing to MVFR at times.
Rain will taper off this evening with improved VFR conditions and
winds coming out of the south.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...

The overall pattern looks a lot like two days ago with the upper
level trough over the eastern Bering Sea and a front pushing large
amounts of moisture onshore from Cordova eastward. The jet stream
can be see in conjunction with the front running from around 40N
into the north Gulf coast between Cordova and Yakutat.
Accordingly, this is the area where the heaviest rainfall is
occurring this morning and it will edge eastward over the course
of the day.

The Cook Inlet and Mat-Su corridor is west of the front but the
moisture east of the upper level trough is bringing in the
rainfall today. This rainfall will be slow to move out as the
trough is moving eastward, but not moving very fast. Flow aloft
is from the Southwest in this pattern and the rain will also end
from southwest to northeast. Kodiak is already out of the
precipitation and Homer is soon to follow. As one heads
northward, the rain will persist longer with Talkeetna expected to
see rain though most of the night Thursday night.

There may be some clearing for the southern Kenai Peninsula
Friday, but the areas to the north really will not be able to
clear out much until the upper level trough starts to move through
the area on Friday night. Until then the mountains will continue
to see showers though by Friday the lower elevations of the Kenai
Peninsula through Mat-Su valleys (including Anchorage) will
probably not see too many showers.

Ridging moves into the area behind the trough on Saturday and
Sunday will be days where there should be a reprieve from the
clouds and rain that have been over the area most of the week.

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...

A progressive pattern is on tap. This morning, the jet was south
of the Alaska Peninsula and there is a closed low at 500 mb north
of the Brooks Range with the trough axis extending over Nunivak
Island and Kipnuk. Expect the trough to dig deeper today and
Friday...impacting Toksook Bay to Bethel and Bristol Bay. The
pattern looks showery with a pool of cold air filtering into the
Southwest. Portions of SW AK will dip below or near freezing
Friday and Saturday morning. Saturday, a transient ridge will
glide across the region and afternoon temperatures will rebound
20-30 degrees. Then another round of shortwaves will drop south
of the Bering Strait.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...

The longwave pattern features a broad trough from the
Beaufort Sea to the Bering and North Pacific. The jet core is
southwest of Attu Island. There is a closed low north of the
Brooks Range that is kicking out shortwaves towards the Bering and
Western Alaska. There is tropical moisture getting entrained into
the northern stream. This forecast period expect the longwave
trough to deepen and the jet will stay south of the Aleutian
chain. A surface low with a frontal boundary will move into the
Central Aleutians Saturday bringing small craft winds. However, its
a pretty mild pattern for the Bering. Expect intermittent showers.

&&

.MARINE (Days 3 through 5: Saturday through Monday)...

The marine forecast will be relatively quiet except for a few
areas experiencing small craft thresholds over the western Gulf
and north of Nunivak Island between Saturday and Sunday. A North
Pacific low could bring small craft conditions across the Aleutian
Chain and Bering Sea between Saturday and Monday, with seas up to
7 to 9 ft accompanying this system. Low clouds and stratus will
persist as the ridge of high pressure remains over the Bering
through Monday.

&&

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

Model solutions now favors light rainfall for the weekend and
Monday as the dome of high pressure from the Bering shifts from
west to east across Southwest through Southcentral and the Gulf
into Monday morning. Tropical moisture from a North Pacific low
following behind the ridge axis could bring light to moderate
showers over the eastern Aleutians and mainly light rain through
AKPEN and Bristol Bay starting Sunday afternoon through Monday
afternoon. On Tuesday, an upper level trough drapes below the YK-
Delta and Southwest Coast brining light rain across Southwest and
Southcentral through Wednesday afternoon.

Farther west, an upper low from the North Pacific moves closer to
the western Aleutians on Sunday, which could be the next main
weather producer for the midweek. Unfortunately, models start
losing their handle on this next system at the same time these
solutions hints for more rain and stronger winds. Clearly, there's
a lot of uncertainty here, so will take another closer look at
future models on where this next system will end up.
