Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
405 PM AKST Tue Dec 26 2017

.ANALYSIS AND UPPER LEVELS...
Alaska remains well out of the storm track as the 250 mb jet
stream is running west to east at around 40N across the Pacific.
Over the state, there are upper level ridges over the Alcan border
and western Bering Sea. A trough digging out of the Arctic and
through the Bering Strait to the Alaska Peninsula. This is the
trough that will usher in the upper level low that will impact the
weather for the second half of the week.

At the surface, there is generally high pressure over the mainland
part of the state with a weak trough along the north Gulf coast.
This will allow some gusty north to northwest winds in the usual
areas along the Gulf coast. The high pressure will also enhance the
low level inversions around the area which will lead to some areas
of fog and/or low level stratus. Strong winds are relegated to the
western Aleutians where a front is slowly moving into the area from
the southwest.

&&

.MODEL DISCUSSION...
Models are in good agreement through the first two days over the
Aleutians and three days for the Gulf of Alaska and Mainland areas.
By late Thursday there becomes a large degree of uncertainty as to
how the low near the Aleutians elongates in a west-to-east manner
and where individual lows will develop and move from there. This
becomes exasperated in the models, especially over the Bering Sea
and Aleutians into the weekend as the GFS is out-of-phase with the
EC and Canadian solutions by early Saturday. Model ensembles are
showing different solutions to the operational GFS as does the WPC
guidance. What all this really means is that there is a good bit if
uncertainty with the models for the end of the week.

&&

.AVIATION...
PANC...With clear skies and light winds persisting through
Wednesday, the main question will be whether there will be fog,
and/or very low stratus. Conditions are not ideal for fog
development, but the low level inversion is expected to be enough to
cause some low stratus and fog to develop late tonight. This time of
year it is likely that anything that develops will persist through
the entire morning so not improving things on the TAF until the
afternoon.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
Southcentral will remain in a relatively quiet pattern for the next
few days in the absence of any strong surface or upper level
features. A weak upper level ridge over the Gulf will build
northward towards the coast tonight. This will help to strengthen
existing low level temperature inversions and promote more extensive
fog development tonight from Upper Cook Inlet into parts of the
Copper River Basin. The other primary short term forecast challenge
will be modest gap flow winds along the Gulf coast as a weak surface
trough helps to strengthen the coastal pressure gradient while cold
air filters out of the interior. These winds will be limited by a
lack of upper level support, but nonetheless gusty conditions will
be present through favored areas from Prince William Sound to
Resurrection Bay. Skies will begin to trend cloudier by Wednesday
night into Thursday as an upper trough descending over the western
half of the mainland closes off into a broad low and a weak front
moves over the southern Gulf. This front will bring increasing
chances for light precipitation to the Gulf waters and locations
along the immediate coast by Thursday morning.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
The longwave pattern features a dome of high pressure over the
interior with ridging extending into Southwest. There are remnants
of a midlevel low near Russian Mission. As time elapses an arctic
trough will dig into southwest bringing cold air into Bethel and
Aniak. The primary forecast challenge will be sky coverage and
temperatures. Locations where the sky is clear, expect strong
radiational cooling at night. This forecast package went for min
temperatures in the teens for many interior locations and for
Thursday morning progged single digit temps.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
The longwave pattern in the Bering features a high amplitude ridge
with the axis near Amchitka and a trough axis near the Pribs and
spanning to St Matthew. On the Himawari satellite there is a frontal
boundary west of Attu. As energy from this system enters the region
the high will pinch/close off and push northward increasing the
likelihood for unsettled weather over Attu and Shemya later this
period in the form of gusty winds and rough seas.

&&

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

We are still on tap for an upper trough to drop into northwest
Alaska resulting in an upper level low forming in the base of the
trough over the western interior Thursday. The upper low is still
expected to take up residence over the Seward Peninsula region into
the weekend before being pushed north as a trough to the arctic
coast Saturday/Sunday time frame. Meanwhile, an upper high over far
eastern Asia drifts west and an upper low pushes to south of the
Aleutians Friday. This translates to the main activity with respect
to surface lows remaining along or just south of the Aleutians
through Sunday. The upper level low then pushes to the eastern
Bering Sea in the vicinity of the Pribilof Islands Monday.
This drags the surface low north to the Pribilofs as well.
However, overall model agreement with respect to the surface lows in
particular is poor heading into the weekend and doesn't fair much
better moving into Monday and Tuesday. Considering potential
solutions of a large low centered in the eastern Bering to a strong
large low south of Kodiak Island, and the difference being a strong
southerly push versus east to northeast offshore flow off the
southern mainland, we are taking an approach of trending with the
ensemble mean solutions and not making any drastic changes beyond
day 4 (Saturday).
