Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
432 PM AKDT SAT SEP 10 2016

.ANALYSIS AND UPPER LEVELS...
A rather amplified upper level pattern is over the state this
afternoon with a strong ridge over most of the mainland part of
Alaska and a strong low near the central part of the Aleutian
Islands. There is a good amount of upper level support around
these systems as the 250 mb jet stream is running south of the
Aleutian low and then north and around the mainland ridge. Strong
subsidence under the ridge combined with weak onshore flow in
southwest mainland Alaska has brought some persistent fog into the
Kuskokwim delta through early afternoon. This should start to
diminish as the approaching low creates better mixing throughout
the boundary layer.

&&

.MODEL DISCUSSION...

Models remain in good agreement with very little to discuss. They
are all bringing the rain into southwest mainland Alaska tonight
and into South Central Alaska Sunday morning. The heaviest
precipitation amounts are all shown to be in the Prince William
Sounds area Sunday night. The only real item worth mentioning is
the higher resolution NAM model shows downslope greatly
diminishing the rainfall in the Anchorage area and the other areas
prone to downslope in southeast flow.

&&

.AVIATION...
PANC...One of the big questions for Sunday around PANC will be
wind shear. The Turnagain Arm wind will be blowing very strong and
wind shear will be dependent on where these winds go when
reaching Cook Inlet proper. At this time it looks like some gusty
southeast winds will move over the airport early Sunday morning
and then the gradient will become more down-Inlet Sunday afternoon
causing the lower level winds to become northeast to east but
winds above the surface will be increasing and remain from the
southeast causing the threat of significant wind shear over PANC.

&&

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

A very impressive low straddling the Aleutian chain will track a
warm front into the Gulf of Alaska tonight through Sunday, with
clear skies quickly giving way to extensive clouds and rain
across most of the region through the day Sunday. The actual
surface low will move through the Kuskokwim Delta, but with a very
stout coastal ridge in place, this will accelerate powerful winds
through favored E-W oriented mountain gaps including Turnagain
Arm. As a result, a high wind warning will be issued with this
forecast package with winds expected to exceed hurricane force
(75+ MPH). Winds will also be strong along the upper hillside of
Anchorage, with some gusty southeast winds eventually crossing
through all of town by Sunday night. While these winds in
Anchorage proper will be below high wind warning criteria, with
the extensive foliage on trees, there may still be some tree
damage to smaller branches, especially across south and west
Anchorage where the strongest winds in town will occur. As the
winds weaken Sunday night, the heaviest rain is expected to move
inland and will last through Monday morning as the front moves
eastward. Showery and cloudy weather will continue through Monday
as the main upper trough moves through the region.

Along the coast, rain will be locally heavy at times with local
streams and rivers expected to rise rapidly in response. Rivers
will remain well below flood levels, but those who are prone to
fast riving streams and rivers should remain cautious.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
The mainland forecast will be dominated by the front/low pressure
system spinning out over the Bering Sea. The warm front will push
onshore late this evening into the overnight hours, spreading rain
from south to north. Rain will be especially heavy and prolonged. Along
with the front will come gusty easterly winds, especially through
the gaps of the Alaska/Aleutian range. Steady rain will continue
even after the front passes Sunday morning as the jet stream
lingers overhead along with a plentiful moisture tap from the
subtropics. These conditions and disturbances within the flow will
bring a second round of widespread steady rain on Sunday. The
trough is still overhead on Sunday night into Monday, but the
frontal forcing will be past. On Monday, lingering moisture and
upper level forcing will continue areas of rain that will taper
off from west to east across the area.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
The warm front draped across the Bering will continue to bring
rain and areas of fog from the Adak area through the Pribilof
Islands and eastward toward the mainland. Gale force winds will
continue tonight but drop off by Sunday. The whole system will
linger over the eastern Bering through Monday, continuing areas of
rain, but a weakening trend will begin today. High pressure will
build over the western Bering before a new front approaches late
tomorrow.

&&

.LONG TERM FORECAST (Days 3 through 7)...
The upper levels have a trough sweeping through from the north which
brings a swath of showers across the northern AOR by Tuesday before
exiting our region by Wednesday morning. While upstream an amplified
ridge is located over the Eastern Aleutians extending into the northern
Bering resulting in patchy fog/stratus. This feature get pushed eastward
going into Wednesday resulting in sunny skies for the Southcentral/Southwest
region. Meanwhile, a storm force North Pacific low is located over the
Western Aleutians with a triple point low positioned just southwest
of Unalaska. This system brings gale force easterly winds through the
central/western Bering as it tracks eastward. By Wednesday, these two
lows phase into one system located just west of Nikolski accompanied
by gale force northeasterly winds through the Bering. Therefore, look
for a showery weather regime as this system tracks along the Alaska
Peninsula by Friday. Therefore, the Bering/Aleutians will be dominated
by northwesterly flow with gusty gap winds along the Eastern Aleutians.
Look for a secondary low to develop in the Gulf by Thursday with gale
force southeasterly winds along the northern Gulf. This system moves
inland by Thursday afternoon with the bulk of the precipitation along
the northern coastal communities. Otherwise, the Gulf of Alaska will
be influenced by southerly flow bringing a scattered showery regime
for the Southcentral region heading into Friday.
