Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
520 PM AKDT Thu Oct 7 2021

.ANALYSIS AND UPPER LEVELS...

Today represents a brief break between systems. Yesterday's broad
low is now well into the interior of the state. In its wake, it
left plenty of moisture and westerly flow. This led to continued
drizzle, low clouds, and some fog stretching across much of
Southcentral. Some fog and light rain also held on much of the
morning across Southwest AK.

The rest of the area is primed for the next system. This low is
rapidly developing over the southern Bering. It is in a favorable
environment for deep cyclogenesis. A strong finger of the
subtropical jet at 300 mb (30,000') is supporting it at 130 kts
as it flows from southwest to northeast. There is deep moisture
moving up with this system as well which is helping to create some
convection over the North Pacific and produce a few lightning
strikes this morning. The final component for this system is some
colder air spilling over the Western Bering from Siberia. 850 mb
temperatures over that area are currently -11 C where by comparison,
they were 1C on the Cold Bay sounding this morning. This cold air
will help to create the thermal gradient this system will feed
off on and allow for some of the gustier winds to mix down over
the Aleutians.

&&

.MODEL DISCUSSION...

Models are in good agreement which is leading to moderate
confidence in the forecast. There are some key issues to note.
First, the deepening surface low over the Bering took a bit of jog
to the north overnight. So instead of coming onshore near Cape
Newenham Friday morning, it now looks like it will pass over
Nunivak Island before crossing into Western AK. The net effect of
this is likely stronger winds over a longer fetch into Bristol
Bay. Thus, a Coastal Flood Advisory remains in effect for the
Bristol Bay coastline. This northerly jog could also make for
slightly less wind for the Aleutians and Alaska Peninsula. Another
area where models are struggling is with the developing triple
point low over the north and western Gulf of AK Fri afternoon.
The exact track of this low remains somewhat hard to pinpoint as
the ECMWF and NAM keep it further north and move it into Prince
William Sound faster. Meanwhile, the GFS has held it slower and
further south. Forecast update with this feature were minimal
today as we wait for better model certainty.

&&

.AVIATION...
PANC...Light southerly winds and abundant moisture will keep
ceilings hovering just below VFR this afternoon. Things should
slowly break up as some dry air starts to work in this evening,
but the timing of this is highly uncertain. The next front will
race towards the area late tonight bringing another bout of south-
southeast winds. The best chance for gusty SE winds is between
11-15z. After that, the down-inlet gradient should shift things
out of the north. Light rain should start overnight and create
the potential for some MVFR ceilings.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 3: Today
through Sunday afternoon)...

Wet conditions return as a low in the Bering pushes a front
through Southcentral. Cloud cover increases into the evening,
with areas aside from Kodiak remaining mostly dry until late
tonight. The bulk of the precipitation will fall as rain Friday
morning as the advection of warm air in southerly flow keeps
overnight lows above freezing. Localized areas of moderate to
heavy rainfall are expected along coastal areas on the eastern
Kenai Peninsula and Prince William Sound. Over higher terrain,
colder temperatures will likely produce snow, with accumulations
possible in Broad Pass and near Paxson. For now, accumulations
look to remain below advisory criteria. As well as rain and snow,
the frontal passage will also bring gusty winds through the
Kamishak Gap and through Turnagain Arm Friday morning.

Low pressure lingers in the Gulf through Sunday as a low forms at
the triple point. Though it moves into the Prince William Sound by
Saturday, broad trough remains in the Gulf. Precipitation lingers
through Saturday before beginning to diminish Sunday as a ridge
builds in from the west.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 to 2: This afternoon
through Saturday night)...

A deepening Bering low with accompanying occluded front will
continue to move towards the area tonight. This will bring
increasing winds and moderate to heavy rain at times overnight.
The low will move inland on Friday with showers across much of the
area. Most areas will receive between a half inch to an inch of
rain through Friday. Additionally, with persistent southwesterly
winds there is a threat of coastal flooding Friday (see the
coastal flood advisory for more details). By Saturday the low
slowly moves northeast and weakens with showers still a good bet.
By Saturday night the showers will decrease in coverage, but still
chances of precipitation with best chances in higher elevations.
The snow level with range between 1500 and 2500 feet through
Saturday with snow in the higher elevations above 1500 feet,
Saturday night the snow level will drop to near the valley floors,
but not much snow expected for the lower elevations due to a
decrease in moisture.

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 to 2: This afternoon
through Saturday night)...

A deepening storm force low will move across the Bering north of
the Pribilof Islands towards Nunivak Island tonight. This will
spread high winds across the eastern Aleutians and the AKPEN this
afternoon through tomorrow afternoon (see the high wind warnings
for more details). Friday afternoon the low will move into
Southwest Alaska with storm force winds south of the low near the
AKPEN and slowly weakening to Gales by Friday evening and these
will gradually weaken by Saturday night. A gale force low is
expected to move across the western and central Aleutians on
Saturday and move into the Bering Saturday afternoon. There is a
chance for some storm force winds near the western and central
Aleutians Saturday, but there is some uncertainty in this.

.MARINE (Days 3 through 5: Sunday through Tuesday)...

Bering Sea:
A wind-wrapped low in the Bering Sea spreads high-end gales
across the Bering Sea and westerly gale force winds along the
Aleutians for Sunday morning. This low tracks north of Bristol Bay
Monday afternoon through Tuesday morning, spreading westerly gale
force winds across Bristol Bay for late Monday night, diminishing
Tuesday. Seas to 18 feet across the Bering Sea along the
Aleutians, subsiding Tuesday. A strong, wind-wrapped North Pacific
low approaches the western Aleutians early Monday morning and
moves into the Bering Sea through Tuesday morning. This low
spreads southwesterly storm force winds south of the Aleutians
Monday morning through Tuesday morning, and high-end gales across
the entire Bering Sea Monday night through Tuesday morning. Seas
building to 23 feet south of the Aleutians through Tuesday
morning.

Gulf of Alaska:
Strong westerly gales across the Gulf and northwesterly gale
force gap winds through the Barren Islands Sunday morning,
diminishing Sunday afternoon. Seas to 21 feet spread across the
Gulf, diminishing Sunday afternoon. A well-developed low moves
into the Gulf Monday morning and strengthens through Tuesday
morning. This low spreads storm force winds across the southern
Gulf and southeasterly storm force winds along the East Gulf Coast
Monday night through Tuesday morning. Seas to 19 feet across the
southern Gulf for Tuesday morning.

.LONG TERM FORECAST (Days 4 through 7: Monday through Thursday)...

The storm track appears to shift southward next week, with fewer
impacts on the mainland than this weekend. On Monday, a weakening
occluded low tracks eastward into Southwest Alaska, with light to
moderate precipitation expected there, diminishing through Tuesday.
To the southeast, a triple point low develops in the southern
Gulf, bringing rain to Kodiak Island and gusty winds through gaps
and passes along the AKPen in the lee of the cyclone Monday and
Monday night. Model guidance has trended south and eastward with
this system, tracking the system further from the mainland into
the eastern Gulf on Tuesday, however the possibility of gusty wind
and precipitation along the north Gulf coast remain possible with
this system as some uncertainty in the track of the low remains.
Another low moves into the western Bering on Monday. This low
traverses the Bering quickly, crossing into the Gulf near Kodiak
by Wednesday. Supported by a weak shortwave aloft, the system
remains elongated with the bulk of its rain remaining south of the
low center, confining rainfall primarily to the Aleutians, AKPen,
and Kodiak Island, though there is some uncertainty in the track
of the low. By Wednesday, a tight pressure gradient between the
low in the Gulf and ridging in the Bering has the potential to
produce gusty gap winds through the AKPen and eastern Aleutians
once again.
