Southcentral and Southwest Alaska Forecast Discussion...CORRECTED
National Weather Service Anchorage AK
454 PM AKST Sun Dec 24 2017

.ANALYSIS AND UPPER LEVELS...
Little overall has changed. A negatively tilted upper long wave
trough extends from eastern Russia to over the northeastern
Pacific. On the eastern flank is a slowly retreating ridge
extending north from the eastern Gulf to along the Alcan border.
At the surface a weak frontal boundary extends from southeast
Alaska to over the western interior. Generally light rain and snow
were observed with this feature across the Gulf/Kenai Peninsula
and snow in the interior. Elsewhere, a weakening low south of the
Alaska Peninsula is producing rain/snow showers across the Alaska
Peninsula and near Kodiak Island. Further West, unstable
conditions under a broad upper trough is producing widespread
showers across much of the Aleutians and Bering Sea.

&&

.MODEL DISCUSSION...
Models are in generally fair to good agreement through Tuesday.

&&

.AVIATION...
PANC...VFR conditions and light winds will persist.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
The front in the Gulf has slowed down quite a bit from yesterday,
but will continue to move inland over the next 24 hours. The air
over the mainland is cold and dry, with the highest dewpoints in
the 20s. This means that although some coastal locations have seen
rain with the front, as it progresses further northward,
precipitation should change over to snow. The dryness of the air
will also impact how much snow falls, bringing slim chances of a
Christmas snowfall in Southcentral, particularly for areas just
west of the mountain ranges.

Temperatures will continue to cool off for the coastal regions,
and remain seasonably cold in the valleys, so tonight and
Christmas night will be quite chilly. This will help build a pool
of cold air over the mainland, which will enhance northerly winds
beginning Tuesday as a ridge builds in over the Gulf of Alaska.
Expect gusty winds through the usual north-south-oriented
channels and passes, but this does not look like a major wind
event for Southcentral.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 through 3)...
Winds taper down tonight as the trough across the Southwest to
Kodiak fills and lifts north to the interior. A cooler trend
in temperatures settles across the area with cold air advection
moving inland as a ridge builds across the Bering. Fog will be a
challenge tonight through Christmas Day with a ridge shifting to
the southwest coast along a stable air mass. Steep temperature
inversions will likely set up along coastal areas allowing dense fog
to develop. Coverage and timing for dense fog remains uncertain as
a strong trailing short wave, rotating along the upper low, will
likely produce snow showers which would actually improve
visibilities. Decided to add patchy fog for tonight then areas of
fog for Monday as light onshore flow prevails. Offshore flow
should limit foggy conditions Tuesday into Wednesday.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 through 3)...
Much of the region will move into a quieter and much less
progressive pattern through Tuesday as the broad trough that has
been over the region for over a week now is replaced by ridging
moving in from the west. Before this occurs, one last gale force
low will move through the Aleutians today, but impacts from it
should be comparatively less than many of the lows that have moved
through recently. Ridging will then move through the Western
Aleutians on Monday, allowing for winds throughout the region to
diminish below gale force with generally dry weather through
Tuesday.

&&

.LONG TERM FORECAST (Days 3 through 7)...
The upper level ridge over the eastern part of the state will
weaken at the beginning of the long term period and give way to a
digging upper level low. This low will move out of the Arctic and
set up shop just east of Norton Sound by Wednesday night and
remain near there through the weekend. This will set up weak south
to southwest flow aloft over most of southern mainland Alaska for
that period. The storm track will remain well south of Alaska
through next weekend.

With generally high surface pressure over the mainland part of
the state and low pressure south of the Gulf of Alaska, there
should be mostly dry and cool weather across the region with the
potential for a snow shower in any short waves that develop in the
upper level flow around the low. Gap winds (northerly winds) may
also develop along the north Gulf coast with this pattern through
the pressure gradient at this time does not look strong enough to
make it truly gusty. This will be worth keeping an eye on as winds
could easily increase should a low develop in the northern Gulf as
often does in this pattern.
