Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
437 PM AKDT Wed May 12 2021

.ANALYSIS AND UPPER LEVELS...

A deepening low in the western Bering is moving a front across the
western/central Aleutians along its associated trough axis and
bringing showers west of the Pribilofs and Unalaska. More benign
conditions are seen over the eastern Bering/Aleutians with the
usual low cloud cover observed on satellite imagery. Partly to
mostly cloudy skies will persist across the rest of the mainland
today in a weak flow pattern. Any showers should stay confined to
higher terrain near the Copper River Basin.

&&

.MODEL DISCUSSION...

Models remain in good near term agreement. Differences still exist
with regards to the timing of the front moving into the Gulf on
Friday. A GFS/NAM blend was favored. In any case, rainfall should
remain mostly confined to Kodiak Island and the Gulf coast and be
non-impactful.

&&

.AVIATION...

PANC...Sea breeze off the Inlet will persist through the afternoon
hours. Some Turnagain wind will develop during the evening, though it
is not expected to be as strong as previous days.

&&

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

The low that moves across the north Gulf coast into the Kenai
Peninsula yesterday has mostly dissipated this morning leaving
just a few rain showers over southern Cook Inlet. The cold upper
level low remains over the Kenai Peninsula and with it some cold
temperatures aloft. This is keeping the atmosphere unstable and
therefore some afternoon showers around Southcentral are not out
of the question, the low-level heating will be limited so the
extent of showers will be generally over the mountains.

A new low south of the Gulf of Alaska can be seen on satellite
this morning, but this one will track east of Cordova and limit
rainfall to eastern Prince William Sound eastward tomorrow.

In general, there will be mostly cloudy skies with some sunny
breaks across Southcentral the next few days. The cold
temperatures aloft will cause some afternoon and evening cumulus
clouds to build a little but showers should remain mostly over
the mountains.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 through 3: This
afternoon through Saturday)...

High pressure remains dominant over the area, the only weather of
significance are a few showers that have developed due to daytime
heating and weak instability these showers will taper off tonight
with clearing skies. Some patchy fog is possible tomorrow morning
mainly along the Southwest coastline including King Salmon and up
towards Hooper Bay. Thursday winds will increase from the east
and southeast creating cross-barrier flow. A few showers will
once again develop over the higher terrain due to heating and
instability. Some showers may drift into nearby valley locations
but most of the area will remain dry. By Thursday night into
Friday a front will move out of the Bering and inland bringing a
good chance of rain for many areas as well as an increase in winds
with gusty winds near coastal locations as well as the typical
gusty winds at Iliamna and New Stuyahok. Saturday the front will
dissipate inland but residual moisture, upper level shortwaves and
instability with keep a threat of showers around much of the
area.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 through 3: This
afternoon through Saturday)...

An occluded front will continue to move across the Bering and
Central Aleutians tonight spreading light rain and increasing
winds into the eastern Aleutians and AKPEN Thursday. A fairly
stout shortwave trough will interact with the front on Thursday
with a low forming along the front south of the Aleutians and then
moving into the Bering. This energy will allow winds to increase
from Unalaska to the AKPEN with gales and high end gales near the
gaps and passes in this area. By Friday this front will move
inland with winds slowly decreasing. The parent low of this front
will slowly move across the southern Bering through Friday with
near gale force winds developing south of the Aleutians. This low
will track towards the eastern Aleutians on Saturday with winds
continuing near gale-force south of the Aleutians by Saturday
afternoon and evening the low will begin to move south of the
Aleutians with a decrease in winds across the Bering late
Saturday.

&&

.MARINE (Days 3 through 5: Saturday through Monday)...

A weakening low located over the Central Aleutians will slowly
move east through the Bering and into the Gulf of Alaska through
Monday. There is high confidence this low will have dropped below
gale-force in strength by the weekend. This low will continue to
lose strength as it pushes east, so high confidence continues that
the Gulf of Alaska will see winds and waves below gale-force.
High pressure moves into the Bering after the exit of the low so
quiet conditions are expected there through the weekend.

&&

.Long Term Forecast (Days 4 through 7: Sunday through
Wednesday)...

Models are in good agreement that a high pressure ridge sets up
over Mainland AK Sunday into Monday and continues into at least
mid-week. The last of a series of lows moving into the gulf
enters from the Bering Sunday into Monday, but looks to stay far
enough south not affect the coast. This means mainland AK will
finally see some sustained warming and sun to move us into spring.
High pressure develops in the Bering over the weekend, so quiet
conditions there. Though, maritime fog/stratus can be expected
under the high. Another low moves into the Western Aleutians
mid-week, though that is only low of note in the forecast area.
So, fair weather for most areas expected in the long term.
