Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
442 PM AKDT Fri Apr 7 2017

.ANALYSIS AND UPPER LEVELS...
A nearly stationary low continues to slowly weaken south of
Kodiak Island. The bulk of wind and precipitation is occurring on
and near Kodiak Island, including nearby portions of the Alaska
Peninsula. Showers continue over the northern Gulf and eastern
Kenai Peninsula, though activity is much less than previous days.
Sunshine dominates the remainder of Southcentral Alaska and most
of Southwest Alaska. Deformation on the back side of the low has
weakened, with snowfall beginning to diminish across the eastern
Bering and southern Alaska Peninsula.

Out west, a large storm force low near the Kamchatka Peninsula is
strengthening as it heads eastward toward the Western Aleutians
with a frontal system beginning to spread out from the low center.

&&

.MODEL DISCUSSION...
There are some minor position differences with both the weakening
low south of Kodiak Island and the low which tracks eastward
along the Aleutians the next couple days, but these will not have
any significant affect on expected sensible weather. The main
forecast challenge is increasing chaotic flow aloft as weak upper
level short-waves transit across the Gulf and Southcentral/Southwest
Alaska the next couple days. These waves will affect cloud cover
and probability of showers which will likely be quite variable
across the region.

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

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
Isolated showers will once again move over the Gulf Coast and
possibly the Kenai Peninsula again this evening. This will occur
as cold air aloft rotates around the gulf low, continuing to
create an unstable environment during the evening hours. Some of
these showers may also briefly produce very small hail as they
move over still relatively low freezing levels, which should
dissipate by late evening. Further north over the Anchorage
Bowl and Matanuska Valley moisture and instability are both weak
enough to prevent most showers from forming over the lower
elevations. A better chance of showers then moves into the area on
Saturday as a weak shortwave approaches from the south.

Kodiak Island will see one last round of wind and rain as the low
very slowly weakens to the south. This low however will not
depart the area as initially expected, and will instead reform on
Sunday, bringing the next chance of rain to the area late this
weekend.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 through 3)...
The weak low pressure system remains parked near Chirikof Island
just south of Kodiak Island. This system remains almost
stationary as it continues to fill through the weekend. This
spreads moisture across the Alaska Peninsula into the Bristol Bay
region. Therefore, look for a showery rain and snow regime
through the aforementioned region. Meanwhile, look for fog to
possibly develop late tonight through the Kuskokwim Delta, Lower
Kuskokwim Valley, and the Bristol Bay interior. There should be
enough clearing of skies tonight to allow radiational cooling,
and combined with the low level inversions will aide in
development of fog.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 through 3)...
The northern/central Bering Sea is influenced by northerly flow
accompanied by marine layer stratus. Meanwhile, a storm force low
is tracking by the tip of the Kamchatka Peninsula with the
associated front approaching the Western Aleutians. This brings
gale force southerly winds combined with warmer air resulting in
a wintry mix for the Western Aleutians. By Sunday morning this low
will be located near Adak on the Bering side. While the frontal
boundary drapes through the western to eastern Bering before
crossing through the Eastern Aleutians near Dutch Harbor into the
North Pacific ocean.

&&

.LONG TERM FORECAST (Days 3 through 7)...

The long term forecast will not be seeing drastic change from the
going forecast. Starting late Sunday and extending through early
into the week, the majority of the active weather will stay well
to the south of Alaska. The primary jet stream is zonal and at or
south of the 45th parallel. Low pressure that is presently to the
west of Shemya will become stacked and lose upper level support
through the Sunday and eventually move along the Aleutian Chain.
Behind that system is the next change.

A surface ridge that will build and traverse the AKPEN will
gradually give way to a low that is progged to slide up and
through the Western chain and eventually impact Western AK. At
this stage guidance is stalling a front from this system across
western Alaska and extending through Kodiak. The longer term
forecast was trended towards the GFS and ECMWF through day 6 and
operated on a bigger ensemble blend through day 8.
