Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
415 PM AKST Mon Jan 15 2018

.ANALYSIS AND UPPER LEVELS...
The Active weather continues across the Gulf and southern
mainland, while more benign and showery conditions persist across
the Bering Sea and Aleutians. A weakening baroclinic zone was
evident across the Gulf Coast to over the Matanuska
Valley/Talkeetna mountains. Snow fell along this boundary over the
Matanuska Valley/Talkeetnas while warm air kept precipitation as
rain along the coast. Snow has diminished across much of the
Copper River Basin, except the Talkeetna mountains, however
patchy low clouds have lingered on. A weak barrier jet continued
small craft conditions near the central Gulf coast as well as
Prince William Sound. Further west, the broad upper level trough
with embedded short waves in concert with low level cold advection
has keep conditions on the unstable side across much of the
Bering Sea and Aleutians. This was evidenced by a large area of
showers (mostly snow) across the aforementioned areas. Some
isolated mixed shower activity was observed over the southwest
Mainland.

&&

.MODEL DISCUSSION (through Wednesday afternoon)...
Models overall are in good agreement and reasonable with the
handling of synoptic features through Wednesday afternoon.

&&

.AVIATION...
PANC...VFR conditions and light northerly winds will persist
through tonight. LLWS with mixed rain and snow is expected to
develop Tuesday morning.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
An easterly upper level jet stream out ahead of deep mature low
over the northeast Pacific will drive a warm front westward
across the Gulf of Alaska and Southcentral tonight. This will
bring warm and wet conditions to the Gulf coast, with snow levels
rising to 2000 ft or higher. With northerly low level flow out
ahead of the warm front, the front edge of precipitation will have
no problems spreading over the Kenai and Chugach Mountains.
Surface temperatures will be just below freezing, so it looks
really good for freezing rain from the western Kenai Peninsula up
to Anchorage. Thus, have issued Winter Weather Advisories for
light ice accumulation. Strong easterly downslope flow will kick
in behind the front by midday Tuesday, so precipitation will cut
off and temperatures will warm above freezing.

The Matanuska Valley and southern Susitna Valley will be right on
the northern periphery of precipitation. Do expect some gusty
northeast winds to develop overnight in the Matanuska Valley which
will cause temps to rise above freezing. Will need to keep an eye
on northern extent of precip because there could be areas of
freezing rain where temps remain below freezing. Another area to
watch will be the Copper River Basin where forecast soundings also
favor freezing rain tonight. Right now it looks like the bulk of
precip should remain near the Chugach Mountains.

The Pacific low will make its way to Kodiak Island Tuesday night,
with lots of wind and rain across the Gulf. As the low reaches the
western Gulf, easterly winds will spread through Prince William
Sound, Passage Canal, and Turnagain Arm. At this point, it looks
like winds will remain below warning levels (75 mph or more), but
Portage Valley/Turnagain Arm could come close Tuesday night
through Wednesday. As the low continues westward along the Alaska
Peninsula on Wednesday winds will push into parts of Anchorage and
the Matanuska, with temps likely peaking in the mid 40s. This
storm system will begin to fall apart Wednesday night, with precip
and winds tapering off most places and temps beginning to fall.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
Some lingering showers along the southern Mainland will taper off
this evening, leaving some residual low level moisture in its
wake which will aide in patchy fog development over some areas
tonight into Tuesday morning. The next front approaches the
southwest Mainland from the Gulf Tuesday morning. The front will
break apart as it pushes through the rest of southwest Alaska but
still spread showers over the area. Showery conditions will
persist through Wednesday and slowly diminish through Thursday.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
West to northwest flow will continue to dominate the Bering and
Aleutians bringing showers to the area, until a new system
approaches the Western Aleutians from the North Pacific Tuesday.
The associated front will make it over the Western Aleutians
Tuesday afternoon and then track into the Central Aleutians
Wednesday morning. The front will then stall and dissipate
Wednesday night, as the parent low weakens over the western
Aleutians. Not much warming is expected with this upcoming
system, so it is more likely to be a mix of rain and snow with
the frontal passage, rather than just rain.

&&

.LONG TERM FORECAST (Days 3 through 7)...
No major changes to the long range forecast today as the trend for
quieter and colder weather still looks to be on track. Beginning
Thursday, weak ridging will develop over the eastern half of the
state bookended by a deep low over the SE coast and a rapidly
weakening surface low over the SW mainland. The jet stream will
migrate south keeping the storm track positioned away from
mainland Alaska. An upper level ridge will amplify over the
Bering and move east through the weekend which will lead to
northerly offshore flow over the western half of the state. This
will draw bitterly cold air down from the arctic and steadily
decrease temperatures across most of the area, with the coldest
plunge of arctic air seen over western AK where temperatures could
drop well below average by Sunday.

Further west, models are locking in on the next storm system
moving into the Western Bering on Saturday. A front looks to move
east across the western and central Aleutians over the weekend but
will stall and wash out as persistent high pressure to the east east
blocks any further progression. Past this weekend, models become
disorganized and out of agreement, but generally show the storm
track staying to our south as ridging holds on over the mainland
keeping us in a colder/drier pattern.
