Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
514 AM AKDT Wed Aug 11 2021

.ANALYSIS AND UPPER LEVELS...

An elongated longwave trough and embedded 500 mb upper level low
remains nearly stationary over the Beaufort Sea with the trough
axis extending from the Arctic Ocean to the North Pacific. At the
base of the trough, the jet stream extends from the Kamchatka
Peninsula to the south of the Aleutian Chain and 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 precipitable water imagery, a moist conveyor belt
extends northeastward to southern Alaska with remnants of tropical
systems that will help maintain a very active storm track across
the Pacific this week. This is demonstrated on the 12Z Kodiak
upper air sounding with a moist profile and a total PW value of
1.04," with variable winds near the boundary layer and increasing,
southwesterly winds aloft.

A well-defined surface low can be seen on satellite south of Sand
Point, bringing areas of rain and wind along the Aleutian Chain
and into coastal Southwest, and will then move toward the north
Gulf coast and into Southcentral today. The latest ASCAT passes
shows small craft advisory level winds near the eastern Aleutians
to the southern AKPEN and over the marine areas in the Gulf as
well. The Nighttime Microphysics (RGB) this morning shows areas of
marine stratus over the Bering, Aleutians, and Southwest, with a
mix of clouds over the coastal areas and interior valleys of
Southcentral.

&&

.MODEL DISCUSSION...

The latest operational model runs remain in decent agreement with
the synoptic scale features and on track for an active and wet
pattern over the next couple of days. However, uncertainty emerges
as models are struggling with the timing and amount of
precipitation with the aforementioned surface low heading toward
Southcentral today. The latest NAM guidance has the Mat-Su Valleys
through the Western Kenai Peninsula remaining relatively dry with
downslope easterly flow, while the GFS/EC/Canadian keeps the
areas wet with a moist, southwesterly flow dominating instead.
Current forecast package is leaning on the wetter solution as the
NAM could be the outlier. Out west, a general troughing pattern
will continue to provide cloudy, showery, and cool conditions in
the Bering, Aleutians, and Southwest, with some breaks in between
systems.

&&

.AVIATION...

PANC...Southeasterly winds from Turnagain Arm are expected to
increase and bend back over the terminal this morning. Winds will
then come out of the north this afternoon in response to an
increasing pressure gradient from a surface low south of
Anchorage. The northerly wind is expected to prevail by mid
afternoon as the low moves closer to the Southcentral coast. Areas
of light rain will move over the terminal today with ceilings
lowering to MVFR tonight.

&&

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

The next system is moving into Southcentral today and can be seen
in the GOES-17 satellite imagery pushing moisture into
Southcentral this morning. This system also has a good amount of
moisture associated with it as the CIMSS MIMIC data, which shows
the perceptible water from satellite, is indicating an area of
around 1.5 inches of precipitable water near Kodiak Island early
this morning with higher levels streaming toward Southcentral.
This abundant moisture is important since 06Z models came in with
a stronger downslope bias for the Cook Inlet region until late
this evening which led to a surprisingly tricky forecast for this
afternoon through this evening for the Cook Inlet region. In the
end, the moisture and strong southwest flow aloft (as well as
lifting from 700 mb and higher) should be sufficient to overcome
the downsloping and bring rain into the Cook Inlet region
northward into the Susitna Valley by this afternoon. The
downsloping will probably diminish the amount of rain that will
fall so lowered some QPF values in the Cook Inlet area.

The Prince William Sound region and north Gulf coast east of
Cordova will see the brunt of the heavy rainfall. Cordova and
Valdez may see between 2 and 2.5 inches of rain through Thursday
afternoon before the rainfall starts to taper off. Seward should
be on the lighter side comparatively with a little less than an
inch total accumulation.

The upper level trough that has been hanging tough over the
eastern Bering Sea will finally make a push eastward on Friday and
move over the Susitna Valley and Cook Inlet Friday night. Until
then, there will be showers that persist over Southcentral for
Thursday and Friday.

&&

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

This morning, the jet is moving over the Alaska Peninsula and
there is a closed low at 500 mb over the Arctic Ocean with the
trough axis extending over Nunivak Island. As the forecast period
elapses, expect the trough to dig deeper and impact 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 Thursday morning and Friday morning.

&&

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

The Semisopochnoi volcano which is 140 nm west of Adak has been
erupting the past several days and emitting ash. Additionally, the
Great Sitkin volcano which is 18 nm east of Adak still has a lava
signature that is discernible in VIIRS Day Night Band Satellite
imagery. The longwave pattern features a broad trough from the
Arctic Ocean to the Bering and North Pacific. There is a closed
low over the Arctic that is kicking out shortwaves towards the
Bering and Western Alaska. There is tropical moisture marrying up
with the northern stream. With the placement of the Arctic low,
it looks a little bit like autumn. Expect intermittent showers but
otherwise a fairly benign pattern is expected to continue across
the Bering for the forecast period.

&&

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

The transition to a quieter weather pattern for both the Gulf and
Bering will be ongoing at the start of the forecast period on
Thursday, with a low in the Gulf moving onshore near Prince
William Sound by Thursday night. There is some uncertainly
remaining for the exact timing for the low to move inland, but the
general change in sensible conditions will be about the same
regardless. Seas of 10 to 15 feet and southerly small craft winds
in the central and southern Gulf will decrease to 6 to 10 ft and
below small craft respectively by early Friday morning. Winds will
become westerly over the Gulf through Saturday, with some
potential for winds channeled by terrain to reach small craft
levels from late Friday to Saturday near the Barren Islands and
Kamishak Bay. Seas 7 feet or less and winds below 30 knots are
generally expected for the Bering through Saturday. The one
exception may be along the Western Aleutians north of a low
tracking across the North Pacific, where easterly winds up to
small craft and seas of 8 to 12 feet are possible from Friday to
Saturday.

&&

.LONG TERM FORECAST (Days 3 through 7: Thursday through
Monday)...

Active weather continues going into the end of the week. The
longwave pattern shows upper level troughing over the entire
mainland of Alaska. The core of the jet on the south side of this
trough shoots into around Yakutat. This means later in the week we
can expect weather systems to begin to take more of an easterly
track in the Gulf, with troughing generally shifting east a bit.
As we go into the weekend, models are showing that the overall
pattern becomes faster moving and transitions to a bit more zonal
in nature. This should mean quicker, more transient areas of inclement
and fair weather. In the Bering, models are also showing the next
big system moving into the Aleutians from the North Pacific.

It should be noted that while models generally agree on the
overall pattern to start the long term, they have not been consistent
due to our current tropical influence that degrades their performance.
So, while models do agree to start the long term we have to temper
that with our local knowledge of model performance. Therefore,
moderate confidence later in the week. Models develop disparity in
weather system placement going into the weekend, so confidence
dropping below moderate on placement of those systems. We can say
with confidence that weather will remain active for Southcentral
and somewhat quiet in the Bering. Expect more wet weather with
some sunshine breaking through intermittently.
