Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
442 AM AKDT Sat Apr 22 2017

.ANALYSIS AND UPPER LEVELS...
An upper level trough centered just south of the Gulf has surged
moisture and gale force winds into much of the southern-western
Gulf. This is a bit of a pattern shift the high pressure that has
persisted over the south Mainland/Gulf, and has produced the
first heaviest rain at Kodiak Island since the first week of
April. The good news for most of Southcentral is that a ridge of
high pressure is preventing most of this moisture from moving into
the area, short of a few mid-high level cloudcover.

Over the Southwest mainland radar indicates that showers are
beginning to develop over Bristol Bay with gusty easterly flow.
Further to the west a weakening occluded front associated with a
North Pacific low stretching from the central Aleutians into the
western Bering is bringing rain and gale force winds to the
region. This front will begin to dissipate today as it approaches
the Gulf low.

&&

.MODEL DISCUSSION...
The models remain in very good synoptic agreement in the short
term, so the higher resolution models were mostly used to handle
gap winds. Towards early next week, there begins to be some
disagreement in placing precipitation over Southcentral as the
ridge slides eastward into Canada. The forecast for now favors a
drier solution from downsloping, but this may need to be updated
if the models trend towards the current GFS solution.

&&

.AVIATION...
PANC...VFR conditions are expected for the ensuing 24 hr period.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
High pressure over Southcentral Alaska will slowly drift north and
east through Sunday night. This will allow clouds to increase, but
mild and dry conditions will continue for most inland locations.
Some showers are possible on the Kenai peninsula, just to the
north of a front over the Gulf. Kodiak is right in the path of the
front and will continue to see rain today, which will change to
showers late tonight. The winds over the Gulf and Kodiak Island
will slowly diminish through Sunday night as the surface gradient
slackens.

&&

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

Warm moist air is flowing into the Southwest Mainland as a front
pushes in from the southeast. Surface temperatures behind the
front will warm slightly, however cloudy skies will keep daytime
highs relatively moderate. Amid the moist southeasterly flow,
rain showers will continue in upslope regions of the Aleutian
Range and Kuskokwim Mountains. Gusty easterly winds will pick up
over the Alaska Peninsula and Southwest coastal waters today as
flow is squeezed and accelerates between Bering Sea low pressure
and high pressure over the mainland. The strongest offshore winds
will be channeled through gaps in the Aleutian Range today before
subsiding overnight as high pressure begins to weaken over the
mainland.

&&

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

Broad cyclonic flow will continue through the weekend over the
Bering Sea and Aleutians. With high pressure holding to the east over
the central mainland and the upper-level jet staying well to the
south of the Aleutians, any disturbances that form quickly get
wrapped up into the longwave circulation. The net result of this
pattern will be persistence of the showery regime with marine
stratus encompassing much of the area through the weekend. A gale-
force front over the western Bering will shift west and weaken
through the day today. Easterly winds will continue over most of
the Bering through Sunday.

&&

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

Next week continues to look like a generally cloudier weather
pattern across most of the mainland, with shower activity both
along the coast and also at many inland locations. This will be a
change from the past many days of widespread sunny weather, but
will still be seasonable mild and pleasant in most areas. A large
but weakening and generally benign low pressure system currently
moving into the central Aleutians will slowly make its way to
Southwest Alaska. Winds should remain relatively light throughout
the state as the overall pressure gradient will be minimal.
