Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
411 PM AKST Tue Dec 20 2016

.ANALYSIS AND UPPER LEVELS...
The main upper trough extends from an upper low over the Arctic
through the Brooks Range southwest to the eastern Aleutians. At
the surface an area of multiple low pressure centers extends from
near Unalaska east to Bristol Bay south into the southwest Gulf of
Alaska. A weak upper level trough is pushing north from the Prince
William Sound region into the Copper River Basin. This is a
somewhat unstable airmass that is resulting in periods of heavy
snow showers in northern Prince William Sound and along the
Chugach Mountains. A 140 KT jet streak south of the Gulf of Alaska
supporting the rapid development and movement of the low in the
southwest Gulf of Alaska toward southeast Alaska.

Over Southwest Alaska the upper trough is slowly dropping south,
now along the Kilbuck Mountains into the middle Kuskokwim Valley
resulting in light snowfall. The weak low near King Salmon is
producing showers over the Bristol Bay region and the low near
Unalaska is also supporting a very showery environment from the
Eastern Aleutians to the Alaska Peninsula. Low pressure resides
over the southern half of the mainland, extending over the eastern
Aleutians.

&&

.MODEL DISCUSSION...
The models remain in fairly good agreement at the synoptic level
through the end of this week. The multiple lows from the eastern
Aleutians to the Gulf of Alaska are progged to consolidate in the
North Gulf Coast area south of Prince William Sound Wednesday Night
as a ridge of high pressure builds across Southwest Alaska into
the upper Yukon Valley. The deep cold air will remain north and
west of the Alaska Range. The main concern with this developing
pattern will be the stronger gusty outflow gap winds across the
Kenai and Chugach Mountains.

Over the Bering Sea and Aleutians a broad area of low pressure
is forecast to be over the northern Bering Sea while a flat weak
ridge of high pressure is over the North Pacific and Aleutian
Islands supporting the weak zonal showery regime.

&&

.AVIATION...
PANC...The Cook Inlet/Knik Arm/Turnagain Arm fog has stubbornly
held in all day. Southwest flow up Cook Inlet will likely continue
this trend as fog extends down the Inlet to Nikiski and Kenai.
Breaks in the CIG and VIS will be short. Without a clear signal
for mixing out the inversion and fog until tomorrow morning, it
looks like the fog will remain an issue through the evening and
overnight.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
Eastern portions of Southcentral Alaska will remain under broad
southwest flow with scattered to numerous snow showers through
Wednesday night. The heaviest snow will be along eastern parts of
the north Gulf coast. Over the Cook Inlet area, fog will remain
overnight and into Wednesday morning under the weak flow and
abundance of moisture. Wednesday night into Thursday ridging will
build in from the west helping to clear out cloud cover and
bringing outflow winds to the area. The biggest concern with this
change is for Thompson Pass and the potential for reduced
visibilities in blowing blowing snow.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
An upper level trough moving over the Southwest this evening will
bring continued light snow to the Eastern Kuskokwim Valley into
Bristol Bay. Ahead of this snow, patchy fog that developed during
some partial clearing this afternoon will mix in with the snow
initially, but quickly mix out as instability with the snow moves
in. As this trough moves into the Gulf on Wednesday, a weak ridge
moving in from Bering will bring clearing skies from west to east
throughout the day with widespread N-NW flow. This ridge will
move through the area quite quickly however as weak but progressive
pattern brings another chance of snow to the Kuskokwim Delta by
late Wednesday-Thursday as a weak shortwave moves in from the
Bering.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
Widespread northwest flow and cold air advection will spread rain
and snow showers throughout much of the Eastern Bering and Bering
Sea coast beginning this evening as the broad trough dissipates
over the North Pacific. Winds and showers further to the west
over the Pribilof Islands and Eastern Aleutians on the other hand
will begin to dissipate as a brief period of ridging moves overhead.
Rain and snow showers will then quickly redevelop late Wednesday
followed by continued active weather for the Central-Western
Bering as another gale-storm force low moves into the area late
Thursday.

&&

.LONG TERM FORECAST (Days 3 through 7)...
Outflow winds will be the big issue Thursday night into the early
weekend as high pressure settles over inland areas from the west
and low pressure in the southeastern Gulf continues moving
southeast and away from the region. Attention then turns to a
series of systems that will move northeast into the Bering toward
the mainland, but will encounter resistance from downstream
ridging and eventually result in a west-east longwave trough and
surface-front orientation from the Bering to the Gulf by early
next week. While there is good synoptic agreement in this pattern
occurring, the devil will be in the details of the individual
systems that develop along this frontal boundary.
