rotating around this low into the Prince William Sound area and
into the Copper River basin. There is an upper level ridge over
western Alaska and the eastern Bering Sea. Some moisture is
topping the ridge into the Kuskokwim Delta area and producing some
snow showers. There is an upper level low over the far western
Bering. An associated fairly weak front stretches from the eastern
Aleutians through the Pribilofs and then into the north central
Bering.

&&

.MODEL DISCUSSION...
The numerical models are in fairly good agreement through the
short term. There are some differences with how they handle a low
that crosses the eastern Aleutians Friday night, with the slightly
slower GFS solution preferred.

&&

.AVIATION...
PANC...VFR conditions and light winds will likely persist through
Thursday afternoon. There is still some fog and low clouds over
the Knik arm, and it could move into the airport at times, but
the probability is low. With light winds and clear skies beginning
Thursday evening, the fog should return.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
Areas of fog across the Anchorage Bowl and Kenai Pen should
diminish by late morning. These conditions will likely redevelop
tonight with ridging in advance of the next wave. Snow
showers/rain and snow showers across the northern Gulf will
slowly diminish over the next 24 hrs as the surface low and upper
support slip south. A weak upper wave along with the remnants of
a surface front moves into the western portion of Southcentral
early Fri morning then into western Canada Fri night. This feature
will likely bring some flurries from the Cook Inlet region/eastern
Kenai Pen, across the Anchorage Bowl,to the MAT-SU Valleys Fri.

Strong outflow winds/gales over the western Gulf should slowly
diminish through this afternoon. Outflow conditions over the
eastern Kenai Pen and north Gulf will linger into Fri. A weather
front moving in from the west brings winds and increased chances
of rain/snow Fri night to the western Gulf.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
The Bering front will spread some snow showers across southwest
AK today and tonight. Ridging will bring dry conditions to the
area on Fri. The next front, associated with the low moving into
the central Aleutians, will bring strong southeast flow Fri
evening into Sat. During this period temperatures will remain cold
enough for snow, which can be expected along the coast.
Downsloping across the Aleutian Range will limit interior areas to
snow shower activity.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
Snow showers with some rain showers near the Pribilofs can be
expected today on steady westerly flow. The next north Pacific low
will begin affecting the Aleutians this afternoon, with some snow
over the western Aleutians and rain for the central Aleutians.
Mainly rain will spread across the rest of the chain through Fri.
A brief break Fri afternoon is expected as energy is transferred
to the next low, which will then affect the western islands Fri
night into Sat. Both of these lows will bring warm air into the
Aleutians and Bering, with widespread rain reaching to the
northern edge of the forecast area by Sat. Warm advection
southeast winds ahead of both systems will be strong, as will be
the cold advection northwest winds trailing the low.

&&

.LONG TERM FORECAST (Days 3 through 7)...
A large gale-force frontal system with storm-force gusts will
move from the Central Aleutians and N. Pacific north and east to
the southern mainland and Gulf of Alaska through the weekend. The
overall impact will be a notable warming trend mainly toward the
coast (after a brief colder trend) and an increase in coastal rain
and snow and inland/mountain snow. Any significant snowfall beyond
flurries for inland areas (like Anchorage and the Mat-Su) will
largely depend on potential triple-point low development in the
Gulf moving toward Prince William Sound, which some models show as
a possibility Monday night or Tuesday of next week. Outside of
these features, general troughiness over much of the region will
yield a generally showery regime across the region from Sunday
through the middle of next week.
