Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
404 PM AKDT Fri Sep 8 2017

.ANALYSIS AND UPPER LEVELS...
Satellite imagery this morning indicates an upper level wave
drifting westward across the Gulf of Alaska and Prince William
Sound. Subsidence ahead of this upper level shortwave has been
stronger this morning than expected, allowing for brilliant
sunshine across the Anchorage Bowl, western Kenai Peninsula,
Susitna Valley and Matanuska Valley. However, cloud cover will
continue to increase into the evening hours as the upper level
wave continues to march eastward. In addition, showers will
continue across Prince William Sound well into the evening hours
and a few will spill westward over the Chugach as the upper level
wave pushes onward.

&&

.MODEL DISCUSSION...
Models continue to be in excellent agreement in the short term,
although they have been over-estimating cloud cover today,
especially across western portions of Southcentral. As a result,
the NAM and NAM-Nest were favored today to capture local effects.

&&

.AVIATION...
PANC...VFR conditions and light winds will persist. A light shower
or two could develop along the Chugach mountains but will likely
not bring conditions below VFR.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2...Sat and
Sun)...
A weak area of low pressure will keep weather wet along the coast
with some drying inland. The low will continue to push clouds from
east to west across Cook Inlet and the Matanuska Valley tonight.
It will also continue to bring rain from Cordova through Whittier
into Saturday morning. Due to the low position, NW winds will
continue to be gusty through the Barren Islands and Shelikof
Strait. With little change in the pattern and weak flow
throughout the vertical column, patchy fog will be possible again
Saturday morning in low lying locations. A weak piece of upper
level energy will move from the eastern Gulf toward the Prince
William Sound on Saturday. This will serve to reorient the primary
surface low a bit further north. It will also bring a chance for
showers to inland locations Saturday afternoon (primarily along
the mountains), with a slight chance for thunderstorms along the
Talkeetna Mountains and Alaska Range. The pattern remains largely
the same going into Sunday. The low will start to weaken in place,
which will allow the rain to slowly let up across coastal areas.
There will still be a chance for showers along inland terrain
during the afternoon. There could also be a few more breaks in the
cloud cover, especially late in the day, as some drier air and
high pressure move towards Southern AK to start the week of
September 10-15.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
Rain showers will continue moving through the area into Saturday
as an upper level trough remains overhead. With broken cloudcover
and cool air aloft, the coverage of these showers should have a
diurnal component with the most widespread shower activity
expected during the afternoon-evening hours. Conditions should
then begin to improve throughout the area on Sunday as the upper
trough moves into the Gulf, bringing clearing skies as weak high
pressure develops.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
Northwesterly flow, cold air advection, and rain showers will
continue to create most of the weather over the Central-Eastern
Bering through Saturday. This evening, the most widespread of the
shower activity should occur over the Eastern Aleutians as a weak
shortwave passes over, which will then shift into the AK Pen
Saturday evening as a stronger shortwave moves through the Eastern
Bering. This pattern will then break down for Sunday as a gale
force low approaches the Western Aleutians, producing rain and
gale force winds that will spread throughout the Bering for early
next week.

&&

.LONG TERM FORECAST (Days 3 through 7)...
The upper level longwave trough will remain entrenched over the
state through most of the weekend before heading toward the Alcan
border Sunday night as the upper level ridge over the Bering Sea
pushes eastward over the mainland part of the state. The ridge
will not linger over the state too long as the next trough digs
into the Bering Sea early next week. This will likely put
Southwest/Southcentral Alaska back into a wet pattern as the ridge
over the Yukon amplifies, as does the next trough which puts the
area in moist south to southwest flow aloft.

There is also a possibility that there may be some clearing on
either Sunday night or Monday night over Southcentral as the ridge
transits over the area. This could allow some of the colder areas
such as east Anchorage and the Butte to drop to freezing for the
first time this season. This is not a certainty but it is
something to watch.
