Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
437 PM AKST Sun Nov 26 2017

.ANALYSIS AND UPPER LEVELS...
The strong low in the eastern Bering Sea has become vertically
stacked and is starting to weaken this afternoon. The jet stream
is now feeding a developing low near the tip of the Kamchatka
Peninsula which will become the dominant low by Monday. A weaker
upper level low is over the Alaska Range near Denali and
retrograding westward. The front associated with the Bering Sea
low is elongating over Kodiak Island and the Gulf of Alaska.

&&

.MODEL DISCUSSION...
Models are now in tight agreement with the movement of the large
Bering Sea low having it move across the Alaska Peninsula Monday
and rapidly weaken. A low which is currently near the southern
tip of Kamchatka will move eastward and rapidly strengthen Monday
into Tuesday and the most models are beginning to converge on a
common solution for this one as well by bringing it near Atka by
Monday evening. At least they are close enough to get a reasonable
forecast solution for the Aleutians and Bering Sea. The big
uncertainty right now involves a triple point low which will
develop south of the central Aleutians and the Atka low Monday
evening. This triple point low will rapidly intensify as it moves
east of the main low and then these two lows should merge Tuesday
night in the eastern Bering Sea just west of Bristol Bay. This
type of system is subject to rapidly change in track and intensity
so it will bear watching the next few days to see how it
develops.

&&

.AVIATION...
PANC...VFR conditions and light northerly winds will persist into
Monday.

&&

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

Light to moderate snow has been ongoing much of the day across
western Prince William Sound and Portage Valley. The
precipitation will persist through that area for the next couple
days as a series of progressively warmer fronts move northward
into the coast. The easterly winds out ahead of the fronts will
aid in producing additional locally heavy snow (and eventually
rain) along the coast through Tuesday. In addition to those
fronts, the winds will increase through Turnagain Pass and Portage
Valley, leading to areas of blowing snow which may locally reduce
visibilities and cause hazardous conditions. For now the biggest
question is how strong the winds will be at the valley level,
leading to uncertainty as to how widespread the locally reduced
visibilities from blowing snow will be. For now though, with light
winds in Portage Valley, all of the visibility reductions through
this evening will be due to falling snow until the winds kick up
later tonight, adding the blowing snow component.

As alluded to above, increasingly warmer air moving north out of
the Gulf with each front will begin a steady warmup area-wide
over the next few days as a warmer, cloudier pattern sets up
across Southcentral. Currently Kodiak remains as snow, but expect
that will change over the next few hours. That warm air will
change the precipitation falling in all coastal communities along
the Gulf to a mix of snow and rain as early as Monday morning,
then all rain on Tuesday. The precipitation associated with all
the incoming fronts Monday and Tuesday is not expected to survive
the downsloping expected to the lee of the Chugach and Kenai
Mountains. Thus, places like the western Kenai Peninsula,
Anchorage, the Matanuska Valley, and eastern Susitna Valley are
expected to remain mainly dry, though under cloudy skies with
steadily warming temperatures. The first above freezing
temperatures in over three weeks (since November 6th) are expected
in Anchorage as soon as Tuesday afternoon and no later than
Wednesday.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
The front from the Bering low is breaking apart as it pushes
through southwest Alaska resulting in snowfall diminishing over
the area as well. However, showers will still linger as the low
tracks across the Alaska Peninsula and into the Gulf. On Tuesday,
another front will move in over the area bringing a mix of rain
and snow to southwest Alaska. Most of southwest Alaska will stay
snow but locations around Bristol Bay will receive a strong
enough push of warm air to see some rain.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
The sub 950 mb low in the southeast Bering is still bringing a
wide swath of storm force winds to the southern Bering, Central
Aleutians, and Eastern Aleutians. This strong core of winds will
continue to bring warning level winds to these locations into
tonight before diminishing with the Eastern Aleutians seeing the
warning level winds into Monday morning. The low will then weaken
and exit towards the Gulf on Monday. Another low will then track
in from the west making it into the southern Bering Monday morning
where it will bomb out and bring another round of strong winds to
the Central Aleutians Monday night.

&&

.LONG TERM FORECAST (Days 3 through 7)...
The models have come into much better agreement in the track of a
front that will move through the Gulf late Tue-Wed, which is now
expected to bring gale force winds into the North Gulf/Prince
William Sound, as well as strong winds through Turnagain Arm and
Thompson Pass. This front will also bring widespread snow (mixed
with rain near sea level) from the Eastern Kenai Peninsula
eastward into Thompson Pass. This snow, along with gusty winds
along the front is expected to bring areas of blowing snow,
especially to Thompson Pass where temperatures will remain much
cooler throughout the event. Over the Anchorage Bowl/Matanuska
Valley, deep southeasterly flow and downsloping will prevent
most, if not all of the precipitation from reaching the ground as
the front makes landfall Tue night, with just a chance of snow in
the area as downsloping begins to weaken on Wednesday.

Over the Bering on Tuesday, yet another storm force low will begin
to weaken over the Eastern Bering through Wednesday, however a
very active weather pattern is expected to continue into the
middle of next week as another gale to (potentially) storm force
low approaches the Western Aleutians late Wednesday. The good news
for the Bering Sea/Aleutians region is there is good agreement
that this system will slowly move through the Northern Bering
into next weekend, providing most of the area with a break in the
very active and progressive pattern. Over the Gulf and
Southcentral, the typical setup of cold and dry conditions is
expected to continue until Saturday when there is reasonable model
consensus of a developing triple point low impacting the area for
the weekend.
