Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
445 AM AKDT Wed Jul 26 2017

.ANALYSIS AND UPPER LEVELS...
A cloudy and wet pattern continues across the southern mainland
and surrounding waters this morning with a broad trough situated
across mainland Alaska and a ridge to the west over the Bering. A
closed low center within the trough is diving south over the
Kuskokwim Delta early this morning and is sending a weak front
eastward toward the Kuskokwim Valley and Bristol Bay. Another weak
wave and associated front out ahead of the low center, has made
it to the western Kenai with northward extent stretching to the
Susitna Valley. Areas of fog along weak ridging between these two
fronts is causing visibility reductions between 1 to 3 miles at
times.

The ridge pattern holds over the Bering with the center just south
of the central Aleutians. Abundant Pacific moisture is streaming
along the periphery of the ridge across the Bering. The stable air
is trapping low level moisture near the surface, with steep
temperature inversions bringing areas of fog along this expansive
ridge.

&&

.MODEL DISCUSSION...
Models are in excellent agreement through Thursday with the
current upper low over the Kuskokwim Delta diving south across the
Alaska Peninsula. However, solutions diverge in solutions for the
next approaching wave across the northern Bering on Friday. The
NAM was the favored solution for most edits through the end of the
week, however the ECMWF was favored across the Southwest and
Bering on Friday.

&&

.AVIATION...
PANC...MVFR ceilings and visibilities this morning may diminish
to IFR at times through mid morning as a front slowly moves across
the Inlet. Conditions are not expected to improve until tonight
as low pressure lingers over the southern mainland. A weakly
stable air mass late tonight could be problematic for visibilities
early Thursday morning if there is any clearing tonight, however
stratus is expected to prevail.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
Rain associated with an upper level low centered over the
Kuskokwim delta is expected this morning from the Susitna valley
south through the Kenai Peninsula. Rain will taper off to showers
from north to south as the upper low moves south, which will
push into the Gulf of Alaska near Kodiak Island this evening.
Conditions will be fairly dry over the Cook Inlet area on Thursday
with weak high pressure building into the area. Rain and showers
will move into the eastern Copper River basin from the Yukon
Territory tonight into Tuesday. For the western Copper River
basin and the Susitna valley, some isolated thunderstorms are
possible Thursday afternoon and evening as some surface heating
helps to de-stabilize the atmosphere.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
A potent upper low diving southeast across the area will generate
widespread rain showers today over the Lower Kuskokwim Valley and
mainly interior portions of Bristol Bay, with more scattered
shower activity towards the west over the Kuskokwim Delta. Marine
stratus and fog will also continue to have an influence,
particular over eastern portions of the Bristol bay coastline
where there remains more of an onshore component to the low level
flow. The region will begin a temporary drying trend tonight as
the low departs into the southwest Gulf, with showers tapering off
from northwest to southeast through Thursday morning as a
transient shortwave ridge moves overhead. This should make for a
warmer day on Thursday, with a few peeks of sunshine possible
although much of the cloud cover will likely persist over the
region. Fog should also be less of an issue for Thursday night as
offshore flow develops, although some patchy development cannot be
completely ruled out beneath ridging and with lingering low level
moisture. Rain begins to spread back into the Delta region late
Thursday afternoon with the arrival of another front from the
Bering, with precipitation once again encompassing the rest of the
region on Friday as another disturbance moves in from the
northwest.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
Extensive fog and stratus will remain in place over a wide swath
of the Bering under the northern periphery of the strong Pacific
ridge centered south of Kiska. A disturbance moving over the top
of the ridge will bring rain to portions of the central and
eastern Bering including the Pribilofs and Dutch Harbor today,
with another system following closely on its heels for tonight and
Thursday. This feature will mostly bring rain to the northeastern
half of the Bering, but a trailing frontal boundary will also
bring an increased chance of precipitation to the Western
Aleutians by late Thursday.

&&

.LONG TERM FORECAST (Days 3 through 7)...
While the guidance is still having some struggles with the long
term there is decent agreement for three of the main features. One
is a ridge extending from the North Pacific into the Bering.
There is also another ridge extending over mainland Alaska from
the east and the third is a low over the Gulf. While all of these
features will have some movement there is good agreement that
they will stay in relatively similar locations from the weekend
into mid next week. This pattern would keep light showers over the
southern mainland that will be enhanced occasionally by
shortwaves rotating around the Gulf low. This type of pattern is
also favorable for fog over the Bering.
