Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
428 PM AKST Fri Nov 11 2016

.ANALYSIS AND UPPER LEVELS...
An upper level longwave trough currently encompasses much of the
Bering and north Gulf coast of Alaska. One upper level vort max
embedded within this trough is currently moving towards Prince
William Sound and is supporting widespread showers across the
north Gulf coast. A second low is centered in the east Bering
just to the east of the Pribilof Island, with an associated weak
front along the Kuskokwim Delta Coast. This system has been
bringing light snow to the Kuskokwim Delta. Meanwhile a quick
burst of showers brought light freezing rain near Iliamna this
morning. To the west of this low broad northerly flow is occurring
along with widespread convective showers.

&&

.MODEL DISCUSSION...

Models remain in good agreement in the short term, as the upper
level low in the Gulf of Alaska pushes towards Prince William
Sound and dissipates, and as the low in the eastern Bering pushes
towards Unalaska Island. There is more disagreement in models
towards the end of the short term as a triple point low develops
in the Gulf of Alaska and moves towards the Gulf of Alaska coast.
Currently the ECMWF is the outlier and indicates a much weaker and
faster low, so a blend of the NAM and GFS was favored.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...

Low pressure moving inland this evening near Prince William Sound
will spread rain showers along the coast and snow showers over the
Chugach mountains tonight. Some light precipitation will spill
over into the Copper River Basin, while the rest of Southcentral
remains dry. On Sat lingering precipitation will diminish along
the coast until the next trough swings through the Gulf to the
coast. Rain and snow will be more widespread, but southeast flow
aloft will keep a rain and snow shadow over Anchorage, the western
Kenai, and the Susitna Valley for most of the weekend.

On Sun the next low racing to the north Gulf coast will bring yet
another round of coastal rain and mountain snow, with areas to the
lee of the Chugach and Kenai mountains once again shadowed from
precipitation.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA...
Low pressure approaching southwest Alaska from the North Pacific
will stall south of the Alaska Peninsula bringing more southeast
flow to the area. This setup will bring more warm air and
precipitation to the area through the weekend. However, most
places will still be cold enough to remain snow. The biggest
problem area is places southeast of the Ahklun Mountains where
there is enough cold air at the surface, but enough warm air
aloft, for a potential for light freezing rain. The threat for
freezing rain will last overnight tonight and into tomorrow
morning.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS...
Cold northerly flow will dominate the Bering and Aleutians for
much of the weekend bringing snow showers to the area. Saturday
afternoon looks to warm up enough for some rain for the Eastern
Aleutians and maybe as far north as the Pribilof Islands, but
otherwise snow will dominate. Finally Sunday night a new system
will approach the Western Aleutians bringing rain to the islands
and a shift in the overall pattern.

&&

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

An area of low pressure over the western Gulf of Alaska on Monday
will continue to bring above normal temperatures and a plethora of
rainfall to the northern gulf coast and eastern Kenai Peninsula
through Tuesday into early Wednesday. A vertically stacked upper
level low associated with this feature will continue to provide
the dynamics required for continued rainfall but will begin to shift
eastward on Tuesday as the upper level pattern upstream amplifies.
A potent shortwave and jet streak will amplify the upper level
pattern starting Sunday night and consolidate into a concentric
upper low south of the Western Aleutians Tuesday morning. This
will amplify a longwave trough over the eastern Bering Sea which
will dry out Southwest Alaska while bringing a period of calmer
weather to Southcentral Alaska by Wednesday. At the same time, the
upper level pattern will shift over the arctic which will allow
some of the coldest temperatures observed so far this winter
across portions of Southwest and Southcentral Alaska. However,
most locations will see temperatures just slightly below normal.
The western Bering Sea will become active Thursday and Friday as
longwave troughing begins to encompass the Bering Sea and a series
of upper level lows push off the Kamchatka Peninsula.
