Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
458 AM AKST Thu Jan 12 2017

.ANALYSIS AND UPPER LEVELS...
A broad upper level trough begins to settle in over mainland
Alaska, cutting off the high pressure over Gulf and Bering Sea.
Stable boundary layer conditions continued through the overnight
hours, with areas of fog and low stratus persisting across various
parts of the cook inlet region. Satellite nighttime microphysics
imagery showed fog and low stratus over the Turnagain Arm and Knik
Arm areas, Kachemak Bay area, Anchorage bowl, and Cook Inlet
coastal areas throughout the night. Satellite imagery also showed
some low stratus and fog across parts of the Southwest mainland,
and fairly widespread stratus was evident across much of the
Bering Sea. Gusty easterly winds associated with a weak frontal
boundary was observed over the central and western Aleutians.

.MODEL DISCUSSION...
Models overall continue to be in good synoptic agreement. The
model trend has been to back the upper trough further west on
Friday and pulling the moisture and surface low with it. The GFS
and Canadian solutions first showed this solution a few days ago,
with the NAM and ECMWF continuing to trend toward the GFS/GEM
solution. This would lean toward increased chances of snow making
it west of the Chugach. So confidence is increasing for measurable
snow Friday afternoon/evening.

&&

.AVIATION...
PANC...IFR/LIFR conditions continue with only brief breaks with
higher ceilings and visibilities this afternoon. Looks like some
colder air along with a little wind could help dissipate the fog
and rise ceilings and visibilities by this evening.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
Today will be the last day before the pattern change over
Southcentral Alaska. The biggest weather challenge for today is
the dense fog in the northern Cook Inlet region. This fog will
remain through the morning hours and is expected to improve by the
afternoon. The increasing pressure gradient down the Inlet tonight
should end the fog as it mixes the surface air and breaks up the
strength of the inversion. The precipitation still looks to be on
track for tomorrow over Southcentral. There will be sufficient
warm air moving into eastern Prince William Sound to turn the snow
to rain in Cordova. The Valdez area may see a mix, but it looks to
remain snow there. Other areas of Southcentral should see
precipitation stay all snow throughout the event.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
Increasing offshore flow will help to scour out any lingering fog
or low stratus today as an upper level disturbance dives out of
the Russian Arctic and digs a trough over the southwest mainland.
The trough will remain overhead through Friday and allow a
bitterly cold air mass to filter into the region over the next
several days, with daytime highs struggling to reach zero across
many interior locations by Friday as overnight lows drop into the
negative 10s or 20s.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
Increasingly windy and showery conditions will spread over most of
the Bering through Friday within a cold northeast flow regime
between high pressure centered over Siberia and the trough digging
over the western mainland. A front associated with a low well
south of the chain will brush the Pacific side of the Eastern
Aleutians and Akpen this evening into Friday, leading to a chance
for more stratiform precipitation in those locations.

&&

.LONG TERM FORECAST (Days 3 through 7)...
Once snowfall from the gulf low makes landfall and dissipates on
Saturday morning, there remains good confidence that very cold
air will descend into the Southwest Mainland and Bering Sea were
it will continue through the weekend into early next week. What is
much less certain is how much of this cold air will reach
Southcentral as the arctic trough sets up to the west. The models
have all trended significantly stronger and further west with a
rapidly developing low moving into the Gulf late Sunday-Monday,
but with horrible agreement its exact track and intensity. The
result of this is a large amount of uncertainty in whether this
system will bring Southcentral temperatures to near normal (EC),
rise well above normal (GFS), or fall well below (GEM) throughout on
Monday. After coordination with WPC, the long term forecast
generally favors the EC and ensemble means, resulting in a
compromise approach with slightly warmer temperatures with another
chance of precipitation early next week. In general, forecast
confidence is highest to the west of the Alaska Range, with much
lower confidence to the east based on this large model
disagreement.

...Snow returning to Southcentral Alaska...

Snowfall will return to Southcentral Alaska beginning tonight and
continuing into Saturday morning as a weather system moves into
the area. Snow is expected to begin along the Gulf Coast tonight
and then spread inland on Friday.

For the Anchorage area and the Matanuska valley, the snow is
expected to begin Friday afternoon and continue overnight. Two to
four inches of snow are currently expected with locally higher
amounts possible, especially along the Talkeetna Mountains
including Hatcher Pass.

This snow event will end Saturday as the weather system moves
north of the area. Another system will move into Southcentral
Alaska on Sunday and Monday, bringing more precipitation to the
much of the area.
