Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
441 PM AKDT Wed Apr 19 2017

.ANALYSIS AND UPPER LEVELS...

An Arctic high pressure ridge at the surface is keeping its foot
firmly planted over most of the state today. The Alaska Range is
helping to block incoming cold from the Arctic and limit the
strongest winds to the Interior.

For Southwest Alaska, the upper-level trough is more problematic.
This feature, which extends from Northern Canada to the Bering Sea,
is keeping a weak area of surface low pressure anchored between
the Pribilofs and Bristol Bay. The resulting pull of the Bering
Sea's cold, wet air is becoming easier with increasing areas of
open water while sea ice diminishes. The result is a sloshing of
low clouds, rain, and snow into the Alaska Peninsula and Bristol
Bay with occasional gusty winds over the Pribilofs.

No substantial change is expected over the region until late this
week and into the weekend as a low moves north toward land from
the Gulf of Alaska and another low moves toward the Aleutian Chain
from the North Pacific.

&&

.MODEL DISCUSSION...
Models appear to be in good agreement in the short-term,
therefore a blend of the GFS and NAM was used today. In the longer
term, models diverge in the handling of both the approaching low
in the Gulf of Alaska and the low in the North Pacific.

&&

.AVIATION...
PANC...VFR conditions and light and variable winds will persist
into Friday.

&&

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

Quiet weather continues across Southcentral for the next day or so
for everyone in Southcentral as high pressure keeps everything
relatively quiet. The air mass behind last upper level front was
not as cool as once thought in the Copper River Basin. As a
result, while the winds through the Matanuska Valley and Thompson
Pass did kick up as expected, they did not get as high as they
likely would have if the air there were colder and more
susceptible to draining. Thus, with a weaker upper level front
currently stalling across the northern Susitna Valley and Copper
River Basin, winds are unlikely to pick up very much with it.
Afternoon sea breezes remain in the forecast around Kachemak and
Resurrection Bays but both should just amount to afternoon breezes
off the water.

With the snow pack having melted and winds lighter than expected,
afternoon relative humidity levels should temper off about where
they are now for the next few afternoons.

From Thursday night through Friday, a strong northward-moving
front that has shown up very consistently in the models for nearly
a week now will finally make its approach into the Gulf. That
front will spell the end of the dry stretch for coastal
communities as low-elevation rain and mountain snow or rain/snow
mix moves into the usual upslope areas on broad easterly flow.
The forward movement of the front will slow to a drift over the
Gulf on Friday as the parent low begins to wrap up on itself,
prohibiting much moisture, and certainly any precipitation, from
advancing very far inland. Thus, Anchorage and points north will
remain dry, and the northern Susitna Valley and Copper River Basin
may even stay sunny. Besides the precipitation at the coast, the
winds will really kick up along the southern Kenai Peninsula
coast, Kodiak Island, and Shelikof Strait, where gales are
expected by Friday evening.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
The pesky upper level low pressure will still influence the area
even though it has weakened considerably. Westerly flow along the
Bering, running into the Alaska Peninsula will be the focus for
marine layer stratus this evening. With it, the possibility for
fog as well. Stratus should move into the Bristol Bay coast this
evening and linger through the overnight hours before dissipating
Thursday morning. Otherwise, expect clear conditions for most
areas except along the coast where both stratus and the upper low
pressure could linger some clouds. High temperatures will run into
the 40s in most areas, but could peek into the 50s as the pattern
changes and some easterly flow brings some compressionally warmed
air off of the mountains. The next real chance for precipitation
comes on Friday afternoon/evening as a disturbance from the Gulf
moves overhead.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
The lingering upper level low pressure will keep snow showers
going over the central Bering Sea. That system will move into the
northern Bering and out of the area Friday. A separate frontal
boundary will parallel the western/central Aleutians late tonight,
peaking near gale-force. The front will bring snow then rain to
the area, staying mainly in the southern Bering. Another system
from the Gulf moves into the area on Friday.

&&

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

For Day 3...Fri night through Sat a front will swing through the
Gulf and another through the central Aleutians. Both will bring
small craft and gale force winds to the their areas, with rain
limited to coastal locations.

For Day 4 through Day 7... Several low pressure centers and
associated fronts will migrate east along the Aleutian chain,
headed ultimately for the Alaska Peninsula and the north Gulf
coast. These systems will bring rain to the Aleutians, and
abundant rain to the Gulf coast. As the systems consolidate near
the Alaska Peninsula over the weekend and into early next week,
rain over the valleys with some higher elevation snow will become
more common over mountain ranges of Southcentral south of the
Alaska range.

The forecast relies on a conglomeration of operational and
ensemble forecasts in an attempt to depict movement and placement
of lows along the chain. This lowers forecast confidence since
the models themselves currently have divergent solutions.
