Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
413 AM AKDT SAT OCT 1 2016

.ANALYSIS AND UPPER LEVELS...
The Southcentral Alaska region is dominated by amplified ridge
positioned over the Gulf extending northward into the Beaufort
Sea. While upstream at 300 mb there is a strong 120-knot
southwesterly jet streak south of the Eastern Aleutians that
transitions to a 80-knot southeasterly jet stream over the
Southwest Alaska coastline streaking further into Eastern Siberian
region. At 500 mb, there is a closed low parked over the Pribilof
Island with a negative tilted trough extending from this feature
through the Eastern Aleutians. At the surface this synoptic
feature is reflected as a 980-mb storm force low that is elongated
from the eastern to northern Bering. This is producing
southeasterly storm force winds from Bristol Bay northward into
the Kuskokwim Bay region. These storm force wind were verified
with a ship observation reporting east-southeasterly winds of 55
knots on the north side of Nunivak Island. The satellite imagery
is showing this occluded system in the aforementioned region with
a huge swath of moisture streaming from the North Pacific Ocean
northward into the eastern Bering, and the Southwest Alaska
region. The scatterometer winds are depicting gale-force
northwesterly winds on the backside of this system from the
northern Bering southward into the Central Aleutians. Meanwhile,
the associated weather front is moving inland over the Southwest
Alaska region with widespread rain, and gusty winds this morning.

&&

.MODEL DISCUSSION...
The models remain in good agreement as the Bering Sea storm tracks
farther north in the Bering as it fills, and tracks into the
Anadyr Gulf by Sunday. The GFS/NAM were the preferred models of
choice for the Bering/Aleutians, and the Southwest Alaska region.
Meanwhile on the east side as the frontal boundary moves through
the Gulf this morning the GFS handled the transition better as a
closed surface low develops in the Gulf by Sunday morning, whereas
the other models wanted to keep this feature as an open trough.
Overall, the ECMWF was consistently the outlier the last several
days. The forecast confidence is above average through the
weekend.

&&

.AVIATION...
PANC...VFR conditions with light surface winds will persist.
Southeasterly winds through Turnagain Arm increase through the
afternoon and evening and may create some low-level wind shear,
especially south and west of the airport.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
As has been the trend the past couple days, the Bering Sea
storm/trough is moving faster than progged. Thus, have moved up
arrival time of clouds, rain, and wind from Kodiak Island on up
to Southcentral. Though high clouds will rapidly move overhead
Today, there will still be dry conditions with hazy sunshine for
much of the region. The exception will be Kodiak Island and the
south end of the Kenai Peninsula which will receive the full
brunt of the approaching upper trough and surface front.

The precip forecast remains a challenge for Tonight through
Sunday Night. While the Bering Sea low lifts northward Tonight,
a short-wave moving through the base of the upper trough will
continue east into the western Gulf where it will develop into
a low. This will cause the surface front to stall and drive most
of the upper level energy eastward across the Gulf, with a much
weakened trough continuing on toward the heart of Southcentral.
As a result, it appears the vast majority of rain with this
system will remain south of Anchorage. Accordingly, have backed
off PoP/QPF forecast. Expect Anchorage, the Mat Valley, the
eastern Susitna Valley, and the Copper River Basin will see
little, if any, measurable precipitation.

&&

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

A potent front continues to create storm-force conditions across
the west coast of Alaska with numerous surface observations and
ship observations reporting winds at or exceeding 50 kts. These
winds will rapidly ramp down this morning as the front moves
inland and quickly falls apart. Nevertheless, gusty winds will be
seen across all of southwest Alaska throughout the day before
diminishing this evening. The strongest wind gusts will continue
to be along the immediate coastline this morning and near Iliamna
this afternoon as winds howl through Kamishak Gap. Rainfall, which
will likely be heavy at times across Southwest Alaska, will
continue through much of the overnight period tonight before
tapering off from west to east. By Sunday afternoon the front will
push into Southcentral Alaska with a very weak shortwave ridge
helping to bring a brief end to rainfall Sunday afternoon and
Monday morning. Rain chances will be on the rise Monday morning as
an upper level trough and weak surface front quickly race toward
the Kuskokwim Delta.

&&

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

The surface low that brought storm force winds to the eastern
Bering Sea has slid just to the east of the Pribilof Islands this
morning and will continue to move to the north/northeast through
the weekend before falling apart over Siberia. The surface front
has almost completely moved inland as of the issuance of the
morning forecast package with 40 to 45 kt winds expected across
the west coast of Alaska through the morning hours before rapidly
diminishing through the afternoon. Focus will then turn to the
back side of the aforementioned low as it appears 50-kt winds
will be likely in and around the Pribilof islands through the
morning hours. A nice isallobaric push will be seen this morning
as a weak high in the North Pacific raises surface pressure over
parts of the Bering Sea. These strong winds will be short-lived
and should diminish as the low continues to weaken and shift to
the north.

Two more systems will impact the Bering Sea through the short term
with the first being a weak frontal boundary that meanders through
the Bering Sea starting this evening and falling apart east of the
Pribilof Islands Sunday Morning. The next system is a developing
area of low pressure drifting off the Kamchatka Peninsula that
should bring a nice shot of rainfall and gale-force winds to the
western Bering Sea and Aleutians on Monday.

&&

.LONG TERM FORECAST (Days 3 through 7)...
The forecast from late Sunday into early next week has trended
slightly cloudier with increased chances of rain into early next
week. There is still very good agreement that a developing low
in the Gulf will bring outflow winds, primarily to the western
Gulf and Kodiak Island, into early next week. The change in the
forecast surrounds an upper level trough from the Bering that has
trended further south, and is now expected to bring widespread
clouds and rain showers to the southern mainland into the middle
of next week. Also due to this trough, outflow winds over the
northern Gulf should be fairly weak without a significant pressure
gradient.

By the middle of next week there remains very good confidence
that a sharp trough forming over the Bering will bring a very
active and progressive pattern to Bering, Aleutians, and likely
the southwest mainland for most of next week. This pattern will
bring a series of at least gale force lows through the region,
which will increase in intensity as the trough strengthens towards
the middle-end of next week. Further to the east over the Gulf
and Southcentral there looks be a very sharp contrast in the
sensible weather with good confidence of a blocking ridge setting
up over the region. This should provide generally sunny and dry
conditions to areas east of the Alaska Range that will likely
persist until late next week. Temperatures in this pattern should
be at or above normal for daytime highs, with overnight lows
falling well below freezing for much of Southcentral.
