Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
418 PM AKST Tue Feb 14 2017

.ANALYSIS AND UPPER LEVELS...
There is a large upper low centered south of the Alaska Peninsula.
Warm southerly flow on the eastern side of this low is pushing
into Southcentral Alaska. An inverted trough is over southwest
Alaska. Cold and showery northerly flow is over much of the Bering
Sea and Aleutians on the back side of the upper low. There is a
blocking upper level high over the western Bering Sea and extreme
northeast Russia. There is a large ridge over the western lower 48
states and western Canada, extending into the Arctic Ocean.

&&

.MODEL DISCUSSION...
The numerical models are in good agreement through the short term
portion of the forecast (Thursday afternoon). The exception is how
the Nam handles the low that moves across the Gulf tonight. The
Nam is weaker and slower than the other models and was not used
for this portion of the forecast.

&&

.AVIATION...

PANC...The southerly winds will diminish this evening. VFR
conditions are expected tonight. Snow is expected to develop in
the morning, bringing conditions down to MVFR, with some brief IFR
possible. Conditions will improve to VFR again by early afternoon.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
As the remnants of the low makes landfall near the Barren Islands,
our active weather pattern continues as another low quickly
moves into the Gulf on it's heals. Before this, gusty winds from
Prince William Sound into the Anchorage Bowl will begin to
diminish later this morning as pressure rises begin to weaken
ahead of the approaching low. The focus then quickly shifts to the
next low which will strengthen to gale force as it moves into the
Gulf late tonight. This will bring variable and gusty winds to
many communities along the Gulf Coast, with the strongest winds
likely occurring near Cordova. Another concern from this system
will be accumulating snow that will develop by late tonight as
temperatures aloft quickly cool enough the support snow. The
heaviest snow from this event will likely begin along the Western
Kenai Peninsula late tonight through Wednesday morning where
around 3-5 inches of snow is expected. There is a chance that this
system will bring advisory level snow to that area (more than 6
inches), however due to the fast moving nature of the low this is
not expected. The low will begin to weaken as it spreads snowfall
northward into the Anchorage Bowl/Matanuska Valley by mid morning,
likely limiting accumulations to less than an inch or two.

The low will then quickly move northward and dissipate Wednesday
afternoon, but yet another low will quickly replace it for late
Wednesday-Thursday, leaving much of the Gulf/Southcentral in an
active weather pattern into the end of the week.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
The Bristol Bay region has a 964 mb low which an associated
weather front swinging through the Bristol Bay interior this
evening. Therefore, the Winter Weather Advisory for snow remains
in effect through this evening. Look for additional 1 to 3 inches
of snowfall with total storm snowfall amounts ranging from 4 to 6
inches. While the heaviest snowfall amounts will occur north and
west of King Salmon. Meanwhile, look for the snowfall to taper-off
as the weather front exits westward into the Kuskokwim Delta this
evening. As this synoptic feature enters the Kuskokwim Delta
region, it will continue to produce blizzard issues with
visibilities one quarter mile or less at times west of Bethel. The
surface observations for Toksook continue to report blowing snow
with visibilities one-quarter mile or less at times with
occasional total white-out conditions as we head into the early
evening hours tonight. Therefore, the Blizzard Warning remains in
effect for the aforementioned region through early Wednesday
morning. Meanwhile, the Bristol Bay region will have some
downsloping along the Aleutian Range this evening as the front
continues to moves westward. While upstream minor upper level
shortwaves will swing thorough the region resulting in a showery
regime through the midweek.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
The northerly flow accompanied by cooler temperature with moisture
filtering into the Pribilof Islands continues to produce blizzard
conditions with visibilities one-quarter mile or less over the
aforementioned region. By this evening the blizzard conditions
over the Pribilof Islands diminishes as the 964 mb surface tracks
near Port Moller area. As this system tracks across the Eastern
Aleutians by Wednesday morning this produce northwesterly flow
from Cold Bay westward along the Eastern Aleutians. Look for cold
advection snow showers from Cold Bay extending westward to Dutch
Harbor. Meanwhile, the rest of the Bering Sea, and the Aleutians
will be influenced by northerly to northeasterly flow as the cold
air continues to filter into the region. Look for continued heavy
freezing spray issues over the Bering with the gusty winds
accompanied by colder temperatures through the week.

&&

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

Beginning the long term forecast Thursday evening, a closed low
over southwest Alaska will be in the process of deamplifying and
and merging with another arctic trough over northwest Alaska. This
will represent itself as snow threats from inland southwest
Alaska to Southcentral, including coastal locations. The snow
threat will continue through Friday and move east as the shortwave
trough moves toward the ALCAN and will continue into Sunday before
drier air filters in across southern Alaska Monday.

Thereafter, a deep low over the Western Bering Sea will track into
southern Alaska Tuesday and Wednesday, bringing widespread
moisture along with it. It is too far out to get too concerned
with exact timing, precipitation types, or amounts, but it does
