Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
453 AM AKST Tue Jan 3 2017

.ANALYSIS AND UPPER LEVELS...
The large blocking high aloft and its associated surface
reflection remain the dominate features for today. In response,
strong temperature inversions remain in place over parts of the
southern mainland. Satellite imagery showed a brief break in the
dense fog over the cook inlet region earlier this morning, as
some higher clouds moved in and temporarily improved conditions.
However, the atmosphere remains primed for fog, and we can see
dense fog lingering along Cook inlet and Turnagain Arm that can
potentially redevelop over inland areas today. Outflow winds were
evident across the eastern Kenai Pen and North Gulf Coast with
generally light winds elsewhere across Southcentral.

Out West, a stalled and fairly weak frontal boundary was evident
across the Ak Pen to over much of Southwest Alaska. Other than a
little light rain, conditions remain cloudy and relatively warm
across the Southwest mainland. Gusty south winds along the frontal
boundary where observed from the AK Pen to over the Kuskokwim
Delta.

&&

.MODEL DISCUSSION...
Models remain in relatively good agreement through the short
term. The models seem to have a good handle on the upcoming gap
wind event for Southcentral later in the week. The higher
resolution models, as is typical, are picking up the gap winds in
the channeled terrain better. One thing the models have not been
handling well, and continue to not handle well, is the potential
for fog development over the cook inlet region. Confidence is low
on the forecast ending of the dense fog this morning.

&&

.AVIATION...
PANC...The big challenge remains the potential for fog, as strong
temperature inversions are likely to remain over the area through
this morning. Expect IFR to LIFR ceilings and visibilities
through this morning, then improving conditions later this
morning.

&&

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

The main challenge for Southcentral this morning is fog duration
along the Anchorage Bowl and southern portions of Matanuska
Valley. An impressive inversion still persists, providing plenty
of stability and moisture trapping near the surface. However,
satellite imagery is indicating that fog is beginning to slowly
dissipate as upper level clouds are pushing into the area from the
west. These clouds are mainly associated with a weak upper level
vort max that currently stretches across the Alaska Range.

A dramatic change in weather is anticipated towards the end of the
short term. While stable air with widespread fog have prevailed
the last several days, an outflow event with gusty winds is
anticipated by Wednesday. Ample support exists for gusty winds,
with the build up of cold interior air at the surface, and an
impressive jet aloft. Currently the strongest gusts are expected
out of Seward and Whittier, but strong gusts are anticipated out
of Valdez as well. &&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
A frontal boundary will continue to bring rain changing to snow
from west to east across most of the mainland. The front is still
nearly stalled over the Kuskokwim Delta where cold rain will
continue to fall within the southerly flow. On the west side of
the front, near the edge precipitation will fall as snow. Near
Bethel, rain will change over to snow in the mid-afternoon with
accumulation under an inch. High pressure settles in behind the
front, along with clearing clouds aloft will promote dense fog
development across the area.

During the evening hours the front progresses into the Kuskokwim
Valley and greater Bristol Bay area. Precipitation will start as a
rain/snow mix in the valley, then change over to snow in the
evening. Accumulation should be around an inch. Little moisture
with the front will make it into the Bristol Bay area, mostly
sprinkles or flurries with little to no snow accumulation. High
pressure settles into the mainland on Wednesday keeping the
possibility of fog in the forecast. On Thursday a front and upper
level disturbance drops in from the north bringing a quick shot of
snow to the Alaska Range.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
The front over the eastern Bering Sea will dissipate today while
high pressure develops over much of the central Bering Sea. A
weak front will clip the far western Aleutians today, followed by
another on Thursday.

&&

.LONG TERM FORECAST (Days 3 through 7)...
Models remain in good agreement in the mid and long range with a
high amplitude blocking pattern developing and persisting through
at least early next week. A shortwave trough will cross the Alaska
and Aleutian ranges Wednesday then continue east-southeast across
Southcentral Alaska and the Gulf Wednesday night. Following this
trough passage north to northwest winds will increase sharply
especially out of coastal terrain gaps. Additionally,
significantly cooler air aloft will push from interior Alaska into
Southcentral Alaska Thursday and Thursday night. The upper level
dynamics supporting the strong outflow winds will weaken Friday
and Saturday as the large upper level ridge shifts slightly east.
However, the deepening pool of cold air in the Copper River Basin
will keep the Thompson Pass and Copper River Delta winds blowing
strong the longest.

Aside from some scattered snow showers possible over the Kuskokwim
Valley and along the Alaska Range on Thursday associated with a
shortwave dropping down from the northwest, southern mainland
Alaska will remain dry for the foreseeable future. The upper
level ridge will initially amplify over the Bering Wednesday night
and Thursday, then shift east over Bristol Bay and western Alaska
through the weekend where it will then remain anchored. A more
active storm track will persist across the western Aleutians where
a series of low pressure systems will continue strengthen and
track north through the southerly flow on the west side of the big
blocking ridge.
