Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
531 AM AKST Fri Jan 27 2017

.ANALYSIS AND UPPER LEVELS...

The main upper-level feature this morning is a longwave trough
centered over the Bering Sea. Ahead of the trough, broad onshore
southeasterly flow over the southern Mainland continues the
relatively warm and showery weather pattern that started
yesterday. Radar shows that the majority of the showers are on the
coastal side of the mountains, with typical downsloping keeping
the western Kenai and Anchorage Bowl mostly dry. A low pressure
system is moving northward through the southeastern Gulf, sending
upper-level shortwaves northwestward through the northern Gulf
coast that are enhancing precipitation. Further west, a surface
low off of the Kuskokwim Coast is slowly shifting northward.
Behind the low, cold air advection showers continue over much of
the Bering and Aleutians.

&&

.MODEL DISCUSSION...

The main forecast question in the short term centers around
precipitation moving into Southcentral this weekend. Models
continue to struggle with the track and intensity of the low
moving up the eastern Gulf Fri night. Most of the effects of this
low will remain outside of our forecast domain, however a
deformation band will extend over Southcentral on the back side of
the low. There are some slight differences in the placement and
timing of this deformation zone and its associated precipitation.
The implication of this uncertainty is lower than average
confidence in the precipitation forecast through the short term.

&&

.AVIATION...
PANC...VFR conditions are expected through late afternoon,
although there is a slight chance of some light freezing drizzle
this morning if moisture from the front in the northern Gulf
manages to slop over the Chugach Mountains. Snow showers will
develop early evening but are expected to be fairly light.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2...Fri and Sat)...
The Gulf low that will begin to make landfall near Cordova later
this morning will bring another round of rain and snow to the Gulf
Coast and Southcentral today. Before snowfall begins over
Southcentral this morning, the 12z Anchorage sounding still
indicates a warm nose aloft with unstable conditions above ridge-
top. As a result, conditions over the Anchorage Bowl and Matanuska
Valley are once again supportive for slop over precipitation
through the Chugach mountains, likely falling as a mix of light
freezing drizzle and flurries. By late this afternoon,
temperatures aloft will begin to cool enough aloft for any
precipitation to switch over the snow at most places as a cold
upper level trough approaches from the southwest. This trough will
very slowly move over the region into Saturday, leaving much of
Southcentral and Gulf Coast under a chance of accumulating snow
into the afternoon. For Southcentral, it appears that the heaviest
and most confident period of snowfall will be towards the end of
the event on Saturday morning as the upper level trough approaches
from the southwest, providing the best dynamics and instability.
Before this, there are some significant differences in the models
as to where a deformation band will setup, leading to lower
confidence in the snow forecast this evening. Overall, this will
be a fairly brief period of moderate-heavy snow for most areas,
so advisory level accumulations are not expected from this event.
Lower elevations of Southcentral will likely see up to 3 inches by
Saturday afternoon, with 6-8 inches possible along higher
elevations such as Hatcher and Turnagain Pass.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
An upper level closed low tracks just Northwest of Nunivak Island
by Friday afternoon, and the associated trough begins to move
through the Southwest Alaska coastline. This synoptic feature
exits the region into the Upper Kuskokwim Valley by Saturday
afternoon. Look for up to 2 inches of snowfall for the Bristol
Bay, Lower Kuskokwim Valley, and the Kuskokwim Delta through
Saturday. The heaviest snowfall will range from 2 to 4 inches
along the Kuskokwim Delta coastline, and along the Alaska Range
during the same time-frame. Meanwhile, as this shortwave moves
through the Kuskokwim Delta coastline, look for areas of blowing
snow to occur from late Friday afternoon through late Friday
evening.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
The gale force low located near Saint Matthew Island tracks
towards Nunivak Island by Friday afternoon before moving over
Saint Lawrence Island by Saturday evening. This produces a
westerly to northwesterly flow through the Bering/Aleutians
through Saturday morning accompanied by a showery regime.
Meanwhile, the Pribilofs will have intermittent snow showers
moving through the region with periods of blowing snow through
Friday evening. By Saturday evening a broad area of low pressure
tracks west of Shemya with an associated weather front moving
through the Western Aleutians. Therefore, look for a wintry mix
along the aforementioned region with gale force southerly winds by
Saturday evening heading into Sunday. Meanwhile, along the Eastern
Aleutians by Saturday afternoon through Sunday morning a
shortwave moves through the Chain, and will likely kickoff some
isolated thunderstorms

&&

.LONG TERM FORECAST (Days 3 through 7)...

Saturday night into Sunday the upper low center over the eastern
Bering lifts north and swings a strong shortwave east from the
western Alaska Range and Gulf of Alaska. This system will bring
light widespread snow across most of the southern mainland and
Gulf Saturday night. A surface ridge transverses the region
briefly on Sunday bringing a break in precipitation across the
Gulf and Southcentral.

To the West...an active weather pattern amidst the broad longwave
trough over the Bering keeps ongoing precipitation across the
Aleutians and Southwest. A significant storm system brings a warm
front into the Western and Central Aleutians Saturday night
through Sunday. Max southeasterly gales winds are expected to
accompany the front along with snow and a brief period of rain as
warm air intrudes into the southern Bering. This front progresses
to the Pribilof Islands, eastern Bering and Alaska Peninsula on
Sunday.

The next system to monitor for gusty winds and snow across all of
the southern mainland and surrounding waters moves into the
western Aleutians Sunday and tracks quickly eastward. This stacked
low pressure system will spread snow across the Bering and
Aleutians on Sunday and then into the Southwest late day. This
system may edge into the western Gulf and Southcentral by Sunday
night however models have not come into agreement with the surface
low track and frontal progression.
