Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
633 PM AKDT Wed Oct 9 2024

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3)...

A cold upper level low in the Interior of the state has a trough
extending over the Alaska/Aleutian Range and meeting up with a
weak surface low in the Gulf of Alaska. Showers moving through
Prince William Sound this afternoon are spilling over to the
western side of the Chugach mountains. However, precipitation is
fairly light with plenty of dry air remaining at the surface for
Anchorage. These showers will continue to move across the area
through tonight with the lower layers saturating towards the wet
bulb. On the upper air sounding this afternoon, the wet bulb
temperature at the surface is around 37 degrees and cooling to
around freezing at 1250 feet. The main forecast challenge
continues to be for precipitation type for tonight into Thursday.
Temperatures are expected to cool some, but little temperature
advection is expected for colder air. The airmass may not be cold
enough to bring all snow down to sea level for Anchorage and the
Matanuska Valley. However, temperatures will be close and the late
night and early morning hours could cool things enough to mix
some snow in with rain showers for these areas. We are still
looking for snow levels to be in the 500 to 1000 ft range along
the Kenai and Chugach Mountains. This means that any precipitation
overnight for areas from around Hillside drive or higher in
Anchorage should see snow. Turnagain Pass is also likely to see
some snow with these showers. If traveling along the Seward
Highway though, expect sudden shifts in precipitation type.
Chickaloon Pass may also see snow tonight into Thursday morning.
Amounts in any of these places are not expected to be very high,
but it may be the first snowfall of the season for a number of
areas, especially ones with just a little bit of elevation.

The upper level trough moves through Southcentral and into the
Copper River Basin Thursday. This could bring in some snow showers
to the Copper Basin with it, but it is looking doubtful that
enough moisture will make it across the mountains to do much.

The next system is a very strong one that will move quickly
through the Bering Sea and send a strong front into the
southwestern Gulf Thursday night and the rest of the Gulf through
Friday. This will hit Kodiak especially hard with strong winds and
heavy rain on Friday. A High Wind Watch has been issued. There is
the possibility for Hurricane Force winds along the north Gulf
coast along the front Friday.

.SHORT TERM FORECAST SOUTHWEST ALASKA AND THE BERING
SEA/ALEUTIANS (TONIGHT THROUGH SATURDAY NIGHT)...

The low pressure system in the Bering Sea continues to deepen and
move eastward. The center of the low currently sits north of the
Western Aleutians, where they have started to see an increase in
winds and light precipitation. Further east, a band of clear
skies ahead of our Bering low will allow for radiative cooling
tonight in Southwest Alaska, bringing temperatures down to the low
20's for select locations.

By tomorrow, the low center will have slid to just southwest of
the Pribilof Islands. A ridge building over Kamchatka is aiding in
some northerly cold air advection getting wrapped into the low,
enhancing the winds on the backside of the storm. The Western and
Central Aleutians look to see sustained gale-force to storm-force
winds for most of tomorrow. The low tracks southeast across the
Alaska Peninsula tomorrow night and into tomorrow morning, where
a triple point occurs. It meanders here for the day before moving
more into Western Gulf Saturday morning.

There are High Wind Watches in effect for the Eastern Aleutians
from Friday morning to Sunday morning, and for the Alaska
Peninsula from Friday morning through Saturday afternoon,
specifically for locations west of Nelson Lagoon. Both of these
areas will see 50 to 60 mph north winds with the possibility of
gusts up to 70 mph. Due to a long and persistent northerly fetch,
seas up to 25 ft are expected in Outer Unalaska Bay and marine
zones north of the Eastern Aleutians.

For Bristol Bay and the rest of Southwest Alaska, we can expect
strong easterly to northeasterly winds Friday and into Saturday.
Winds through Kamishak Gap could reach 50-60 mph and effect
nearby communities. Overall this should be a relatively dry system
with light precipitation in Bristol Bay. Persistent northerly
winds and cool temperatures are expected for the Kuskokwim Delta
through the weekend.

.LONG TERM FORECAST (Days 4 through 7: Sunday through Wednesday)...

By Sunday, the broad low encompassing most of southern Alaska is
likely to have weakened to gale force. A broad swath of gales
will extend across the eastern Bering Sea as cold, Arctic air
streaming southward leads to an unstable atmosphere that will
allow stronger winds aloft to mix down to the surface easily. This
will keep gusty winds blowing across the Pribilof Islands,
eastern Aleutians, and Alaska Peninsula through Monday. Seas,
initially 15-20 ft on Sunday between the Pribilof Islands and the
eastern Aleutians and in portions of the Gulf of Alaska gradually
subside heading into Monday. Precipitation will largely be focused
along the coast of the Gulf of Alaska, as moist, unstable air
rotates up from the North Pacific and is squeezed out along the
coastal mountains in the form of rain showers. There will also be
snow showers across the eastern Bering Sea, eastern Aleutians, and
Alaska Peninsula as the cold, Arctic air surges across the
relatively warm waters of the Bering Sea. Inland precipitation
will be limited by cross-barrier flow and a lack of strong forcing
aloft, though a weakening front may extend into Southwest Alaska
from the Interior on Sunday, which could produce a band of light
snow. All of these precipitation features weaken on Monday as the
parent low weakens over the Gulf and shifts slowly east.

High pressure over the western Bering on Sunday will gradually
work into the northern and eastern Bering and leading to dry
conditions over Southwest Alaska for Monday and Tuesday. For the
Aleutians, conditions will primarily be dictated by the
extratropical remnants of Tropical Storm Barijat (formerly 21W).
The low will center near Kamchatka on Sunday, pushing its front
into the western Aleutians. As the low tracks eastward, its front
will progress to the eastern Aleutians by Wednesday. Southeasterly
winds along the front may reach gale force at times as weak
shortwaves lifting along the front enhance instability and tighten
the pressure gradient. Along the front, precipitation will fall as
rain as the result of warmer tropical air entrained in the
remnants of Barijat. Finally, a chance of light snow occurs for
inland areas of mainland Alaska as a strong shortwave trough
drops south from the Chukchi Sea on Wednesday and brings even
colder air aloft.

Quesada

&&

.AVIATION...

PANC...VFR conditions and light winds will persist through the
evening hours. Ceilings will begin to lower into the overnight
hours as rain/snow showers make their way off the mountains.
Ceiling height is going to depend heavily on where exactly these
banded showers set up which is highly uncertain. However, the
lowest ceilings can be expected between 09Z and 18Z.
