Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
437 PM AKDT Thu Sep 28 2017

.ANALYSIS AND UPPER LEVELS...
An upper level trough extends out the Arctic, through the interior
of the state and southward through the western Gulf of Alaska.
The upper level ridge has greatly amplified from yesterday over
the western Bering Sea. These features will both move to the east
over the next few days bringing in a change to the weather pattern
over the mainland part of the state.
At the surface there remain a low in the western Gulf of Alaska
with ridge over the western Bering Sea which is keeping the
northerly gradient over most of the Bering and Southwest mainland.
A ridge is also along the north Gulf coast which is increasing
winds through Turnagain Arm, the Knik Valley as well as along the
Copper River.

&&

.MODEL DISCUSSION...
Models remain in good agreement through the weekend with the only
item that may cause some impact to the forecast being the low
currently in the western Gulf of Alaska. This low is elongated
with two centers...one just southeast of Kodiak Island and the
other near the southern tip of the Kenai Peninsula. Models
underestimated the strength of the northern most low yesterday
and are still presenting slightly different solutions to it today.
The most likely scenario will be for the southern low the become
the dominant one as the northern one weakens and then drifts
southeastward before dissipating Saturday. Models are still
struggling a lot early next week with two lows moving into the
Aleutians and Alaska Peninsula regions. While the longwave pattern
is similar, the surface low center positions are hundreds of
miles different between the GFS and ECMWF models.

&&

.AVIATION...
PANC...VFR winds will persist through Friday. There is the chance
of the Turnagain Arm wind moving over the airport from late in the
afternoon through mid evening tonight. At this time it looks to
remain mostly just south of the airport so the TAF reflects this,
however there could be some gustier conditions that occur for a
few hours during the aforementioned time frame.

&&

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

A slowly weakening vertically stacked low located over the Gulf
about halfway between Seward and Kodiak will remain the primary
driver for the weather across Southcentral for the next 24 hours
or so. As a result, a general precipitation pattern of rain
showers along the Alaska Range and Prince William Sound with
relatively little in between will continue into Friday morning.
The stout easterly flow across Prince William Sound will keep
potentially heavy rain going across the western portion of the
Sound through tonight. With regards to the winds, the main gap
winds are through Turnagain Arm and through the Copper River
Basin. Both will diminish overnight as the pressure gradient
slackens.

During the day Friday, a front pushing southeastward out of the
interior will cause off-and-on shower activity across much of
Southcentral through the day, though most areas should keep total
rainfall totals from the frontal passage under a tenth of an inch
or two.

On Friday night, the aforementioned front will clear the Cook
Inlet region early in the evening and dissipate over western
Prince William Sound and the Copper River Basin by midnight.
Robust clearing behind the front will commence area-wide, making
for near optimal stargazing and aurora watching conditions!
Anchorage International should get its first night in the 30s,
with those values challenged again Saturday night. Rapidly
building high pressure over interior Alaska along with some colder
air will invigorate many of the gap winds across Southcentral
Friday night into Saturday from Seward, eastern Turnagain Arm,
Whittier, Valdez, and the Copper River Delta as strong offshore
flow develops. The winds should help to keep those affected
communities warmer Friday night.

A weak upper level disturbance clips the Copper River Basin
during the day Saturday making for mostly cloudy conditions there.
Elsewhere, other than for some high cloudiness, the rest of
Southcentral gets to enjoy a day with nearly full sunshine and
highs in the lower 50s. We'll repeat that again for Sunday too!

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
Rain will linger around the Aleutian and Alaska Ranges tonight
into tomorrow morning before ridging builds in from the west.
High pressure will then dominate southwest Alaska into the
weekend.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
High pressure over the Western Aleutians and Bering will slowly
track east into the eastern Bering by Saturday. Behind the
ridging, a front will push over the Western Aleutians Friday night
bringing rain and gale force winds to the area. On Saturday it
will continue its easterly track towards the Central Aleutians and
Bering.

&&

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

The forecast period commences with a high amplitude ridge spanning
from the Gulf Of Alaska to the North Slope and a closed low south
of Sand Point. Upstream, there will be another vortex churning
just east of Kamchatka. Sensible weather-wise, expect another
sunny day on Sunday over the Anchorage Metro area and the Prince
William Sound. As time elapses, anticipate a progressive pattern
as the pair of lows careen eastward. By midweek, another cyclone
moves into the Bering. Overall, past Sunday the models continue
to struggle with this transition period which impact the timing
and the placement of the precipitation shields. High confidence
that next week will be dominated by unsettled and moist
conditions.
