Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
506 PM AKST Tue Dec 27 2016

.ANALYSIS AND UPPER LEVELS...
The upper level pattern is currently dominated by a longwave
trough over the mainland and a strengthening upper level ridge
over the Bering Sea. In the Gulf of Alaska, a cold core low is
reflected all the way to the surface. A second closed upper level
low is currently just north of the Bering Strait. Satellite
indicates a trough associated with the low north of the Bering
Strait dropping down along the west coast. This has brought snow
showers to the Kuskokwim Delta this morning, with radar indicating
that the trough is currently about to move through Bethel.
Elsewhere in the Southwest, the relatively benign weather pattern
has lead to some challenging fog forecasts this morning.

In the east, the low in the Gulf of Alaska continues to rotate
bands of showers onshore. Motion with this low is not very rapid,
allowing showers to linger in one place once they develop.
However, there is not a lot of moisture making it into
Southcentral, so the showers are fairly light, even if they are
prolonged.

&&

.MODEL DISCUSSION...
Models are struggling today to resolve the showers moving onshore
in the Southcentral region. Additionally, as the upper level
feature drops down out of the north, models are differing quite a
bit on what effects this will have in Southcentral. A lot of this
forecast depends on how much moisture makes it into the area from
the Gulf. Currently the thinking is for a drier solution, with
limited snowfall in the south.

By Thursday, models have been very consistent on bringing the
next system up through the Kamchatka peninsula and driving a lot
of warm air across the Bering and into the Southwest. A lot of
uncertainty remains on the progression of this warm air -- how
deep the layer is and whether it will make it east of the Alaska
range to drive out the cold pool currently in place. This makes
the current forecast high confidence that precipitation will
occur, but low confidence on what type and how long it will last.

&&

.AVIATION...
PANC...Snow showers forming over west Anchorage have made the PANC
TAF a bit of a challenge today. During the showers, conditions
drop to MVFR rather rapidly. These showers appear to be clearing
up at the moment, although as mentioned above, model consistency
on location of shower development has been rather poor. Current
thinking is that the break will last until the upper level low
moves in and brings the next batch of snow. Timing on this has
slowed from yesterday and looks like it will occur closer to 12z,
with possible IFR due to vis in SHSN between 15 and 18z.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
The 992 mb low pressure system in the northern Gulf tracks into
the Prince William Sound heading into Wednesday morning. This
synoptic feature will bring in moisture to the Anchorage Bowl, and
coincides with an upper level closed low dropping down from the
north into our AOR. Therefore, look for a couple of inches across
the Anchorage Bowl with higher amounts possible along the
mountains through Wednesday. Meanwhile, look for higher snowfall
accumulations in the higher elevations over the Talkeetna
Mountains, and along the Alaska range through the Copper River
Basin as the aforementioned synoptic feature moves through the
region. As the surface low moves eastward out of the Prince
William Sound by Wednesday afternoon, this will allow the colder
air to filter in from the north coinciding with the upper level
trough pushing through region. This creates increased pressure
gradients, and strong gusty westerly gap winds through the Barren
Islands for Wednesday. Therefore, the aforementioned region will
have storm force westerly winds by Wednesday afternoon through
early Wednesday evening before the winds diminishing to gale force
going into early Thursday morning time-frame. For the most part,
the northern Gulf, and the coastal communities will be under a
showery weather regime.

&&

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

Very busy weather coming up for Southwest Alaska over the next
couple days. At the top is an incoming cold snap that is expected
to send temperatures back down below zero in many areas,
especially the Lower Kuskokwim Valley and interior sections of
Bristol Bay. Elsewhere, single digit lows are expected right up to
the coast of the Kuskokwim Delta and Bristol Bay. This will keep
the scattered snow showers going, especially on the upwind slopes
of the mountains, through Wednesday.

Then things take a complete 180 in the temperature department as
a very strong warm front associated with a low near Russia moves
into Southwest Alaska starting Wednesday evening and progressing
inland through Bristol Bay and the Lower Kuskokwim Valley by
Thursday afternoon. Since it is replacing a very cold air mass, a
short period of freezing rain is likely for most areas of
Southwest Alaska overnight Wednesday night, before most of those
same areas transition to plain rain as temperatures rise. During
the brief time much of Southwest Alaska is in the warm sector,
only light rain showers are expected for most areas due to a lack
of strong forcing. While the warm, moist air moves northeastward
across the sea ice that has built up along the coast, and then the
snow cover inland, that local cooling will bring fog concerns to
coastal locations as the moisture in contact with the ice surface
condenses.

Then cold air returns in short order starting midday Thursday for
points along the Kuskokwim Delta through Thursday evening for
points further east as a strong cold front swings from northwest
to southeast across the entire area. Right now it looks like the
precipitation will be ongoing during this transition, so most
areas should see an increased rate of rainfall at the start of
cold frontal passage transitioning to snow before ending. Due to
the rapid rate the cold front will be moving, no significant snow
accumulations are expected. Most locales outside of the slopes of
the Alaska Range should be done with all the precipitation late
Thursday night.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...

Much of the Bering Sea and Aleutians will be in the warm sector of
the storm from Wednesday through Thursday. Thus, unlike for much
of Southwest Alaska, there is very high confidence all areas stay
rain as most locales from the Alaska Peninsula east warm well into
the 40s on Wednesday and Wednesday night.

With the strong influx of very warm air will be associated strong
winds, especially for the western Aleutians starting late tonight
through the day Wednesday. Warm air moving in tends to not be
favorable for stronger gusts, but sustained winds in the 55-65 mph
range for much of the western Aleutians are expected, this is
along with moderate rains and seas upwards of 40 feet on the
Pacific side.

Impacts are also possible in the Pribilofs as 24 hours of strong
southwesterly winds in the 35-50 mph rant with a long fetch
pushes water levels higher on the southwest sides of the islands,
including the port of Saint George.

&&

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

The forecast today largely follows persistence from yesterday's
forecast.

A highly amplified pattern will dominate the mid-term and extended
period as blocking high pressure tries to become established from
the Pacific extending into much of the mainland by the end of the
period. Initial areas of concern will be with precipitation-type
from Anchorage south through the Cook Inlet region as a weakening
front moves across the region. At this point, the forecast is for
any precipitation that falls Thursday into Friday to remain all
snow in Anchorage, but a changeover to rain can also not be ruled
out at some point, and obviously this could have a significant
impact on travel across the area. To the north toward the Mat-Su
valleys significant snow accumulations will be possible,
especially for south- to southwest-facing upslope areas.

As the triple-point low along the coast moves away toward the
northern Panhandle, a strong jet streak will help to push cold air
through the Alaska and Aleutian ranges and through the Chugach
into Prince William Sound and the northern Gulf of Alaska. Outflow
winds will be quite strong from near Seward to Whittier (and
could briefly threaten high wind thresholds near Whittier) with
moderate gales from Passage Canal through Prince William Sound
late in the day Friday. As that system winds down, high pressure
builds over the southern mainland for the weekend.

Amplified ridging builds over the mainland from the weekend on
through the middle of next week, with an active jet stream pushing
systems from the North Pacific north toward the Bering Strait and
the Arctic. The main area of ambiguity at this point in time will
be with the degree that the systems moving north are able to beat
down the ridge and push weakening fronts into and across the
southern mainland. The main impacts from this pattern will be
warm air pushing into the southwestern mainland and likely
precipitation-type concerns for Southwest Alaska. Toward the
middle of next week, it is possible that ridging becomes re-
established to the west over the Bering, which may allow colder
air to spill south into at least parts of the southern mainland.
