Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
411 AM AKDT THU SEP 8 2016

.ANALYSIS AND UPPER LEVELS...

An upper-level Arctic low is rotating through the southwest
Mainland, embedded within a broader longwave trough spanning most
of the state. Cool and dry northerly air advancing southward
behind the polar low is bringing cooler fall weather to the
southwest Mainland. The cold air behind the low has also
stabilized the environment over the southwest, which has allowed
convective showers to taper off throughout the night over the
Yukon-Kuskokwim Delta. Greater instability is located ahead of the
low, supporting a continuation of convective showers over the
northern Alaska Peninsula, the Alaska Range, and Southcentral
Alaska. Surface high pressure over the Bering Sea continues to
support marine layer low stratus and fog over the Bering and the
Aleutian Islands.

&&

.MODEL DISCUSSION...

Models are in very good synoptic agreement with both the track and
intensity of a Pacific low that approaches the Aleutians tonight through
Friday. Models have been struggling, however, with the handling of
some remnant tropical energy that moves into the eastern Gulf of
Alaska tonight. Previous runs have been quite inconsistent, with
the GFS and the ECMWF tracking a stronger surface low associated
with this energy further west than the outlier NAM. However,
latest model runs have come into better agreement on the intensity
and track of the system. The latest model runs are trending
towards a solution that tracks the low further east than previous
GFS and ECMWF runs showed. This trend keeps the biggest impacts of
this system in the eastern Gulf and out of our forecast area.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
A closed upper low will slowly makes its way from Southwest Alaska
into Cook Inlet today. The eastward progression will be impeded
by a deepening low tracking from the North Pacific toward the
eastern Gulf of Alaska. The two systems will remain out of phase,
however it does look like the upper low over Cook Inlet will tap
into some of the deep moisture moving up from the Pacific. Have
increased shower coverage for the Kenai Peninsula which will be on
the receiving end of this moisture. Isolated to scattered showers
will be the norm for much of the rest of Southcentral with
continued widespread instability.

The upper level low over Southcentral will be pulled southward as
the deep Gulf low lifts northward across Southeast Alaska tonight
through Friday. Tight surface pressure gradients combined with
strengthening northerly (offshore) flow will lead to drying with
decreasing clouds. It will also lead to gusty winds, especially
in bays and passes along the coast. Weak cold advection will
accompany the northerly flow, though the widespread windy
conditions will limit the ability of surface temps to drop really
low on Friday Night.

&&

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

A weak upper level low continues to propagate eastward across
Southwest Alaska this morning with some lingering rain showers
residing over the eastern half of the Bristol Bay Area and Lower
Kuskokwim Valley. Looking at the vertical profile, it appears the
upper level low has been cut off from the surface flow which is
likely attributing to the lack of coverage in regards to the
showers. Nevertheless, showers will be possible along the Aleutian
and Alaska Ranges throughout the day today with some weak orographic
lifting assisting in the generation of rain showers. Friday and
the first half of the weekend actually look quite nice for early
September with clearing skies and high temperatures in the mid 50s
to mid 60s. This nice weather will unfortunately be short lived as
a potent front quickly sweeps across the Bering Sea and into
Southwest Alaska Saturday night and should likely rain chances through
at least Monday of the upcoming week. Some locations along the
immediate coast could see periods of moderate to heavy rainfall
as well as gusty winds approaching 25 to 40 mph on Sunday as the
front begins to move inland.

&&

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

The weather pattern expected to develop over the next several days
is very reminiscent of fall and could very likely be the prelude
to the typical active weather across the Bering Sea observed this
time of the year. You could consider the Bering Sea right now the
calm before the storm. High pressure currently situated across the
Bering Sea leaves little to the imagination as stratus and some
isolated showers dominate the region. However, that is all about
to change as a weak area of low pressure currently migrating
across the northwest Pacific Ocean will begin to interact with a
plethora of upper level support and jet energy quickly diving
south off the coast of Kamchatka this afternoon. With the development
of impressive baroclinicity (negatively tilted trough), the
surface low will develop at a pretty good rate and push a potent
front across the southern Bering Sea Friday and through the weekend.

The combination of high pressure over the Bering Sea and deepening
low pressure over the Northern Pacific Ocean will create a very
compact pressure gradient that will allow 35 to 45 kt winds to
develop along the frontal boundary. There is a decent likelihood
that parts of the Western and Central Aleutians could see
sustained winds of 35 to 45 kt with gusts possibly as high as 55 kt
at times. In addition to these strong winds, heavy rain blown by
the strong winds will likely reduce visibilities. Model guidance
has rainfall amounts exceeding 2 inches in a 24 hour period for
Adak and Atka. This front will move eastward throughout the
weekend with winds gradually weakening as the low begins to
weaken and the front occludes. Nevertheless, gale force winds
looks all but certain across the Eastern Aleutians and Southern
Bering Sea this weekend with periods of moderate to heavy rainfall.

&&

.LONG TERM FORECAST (Days 3 through 7)...
Forecast thinking in the extended term is largely unchanged from
the past few days. A pleasant start to the weekend is in store for
Southcentral AK as a high amplitude ridge builds into the region
on Saturday in the wake of a departing trough. Conditions will
then quickly change by Sunday as guidance continues to show good
agreement on a North Pacific low crossing the eastern Aleutians
on Sunday and moving over the southwest mainland Sunday night,
with an associated front moving through the Gulf of Alaska. This
model consistency lends increasing confidence that much of the
southern mainland will see a period of steady rain beginning
Sunday and lasting through Monday night. The potential for strong
southeast gap winds through Turnagain Arm and other favored areas
will also require additional forecast scrutiny in the coming days
as the low center is projected to take a favorable track near
Nunivak Island on Sunday night. Confidence begins to decrease
towards the middle of next week as the system departs to the
east, however a fairly progressive flow pattern and another Bering
low approaching from the west will generally support a continued
chance of rain across much of the region well into next week.
