Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
420 PM AKDT Tue Sep 1 2020

.ANALYSIS AND UPPER LEVELS...

A longwave trough over the Bering is digging southeastward towards
the mainland this afternoon. The storm that has been impacting all
of southern mainland Alaska the past few days is rapidly
weakening this afternoon, but the remnants of the upper level
feature are still causing some shower activity, particularly over
the mountains north of Anchorage. As the upper level trough
builds into the mainland over the next few days, that will keep
active weather ongoing.

Plentiful moisture remains in place across much of the area, as
evidenced by very low dewpoint depressions. The presence of this
much moisture with even weak forcing is helping keep the showers
active over much of the mountainous terrain. Temperatures are
largely holding in the 50s and lower 60s across the area.

&&

.MODEL DISCUSSION...

The models remain in very good agreement in the short-term,
leading to high forecast confidence. The primary challenges will
be the coverage of rain shower activity over the next few days,
and with a cold air influx moving into portions of Southwest
Alaska, low temperatures will also be a part of the forecast
requiring extra attention.

&&

.AVIATION...
PANC...Expect rising ceiling heights this evening as the last in
a series of upper level waves exits. It does look like some sort
of ceiling will hold in, but if there were any partial clearing,
then fog could develop in the vicinity. Another upper wave will
bring another round of rain in on Wednesday, which will lower the
ceiling back down to low end VFR, with potential for short periods
of MVFR.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3)...

Shower activity will gradually taper off from southwest to
northeast this afternoon and evening. Observations show weak
Turnagain Arm winds developing this afternoon. GOES-17 Day Cloud
Phase Distinction RGB shows isolated convection in the eastern
Talkeetna Mountains and western Copper Basin while satellite
derived lightning detection shows a couple of cloud to cloud
strikes in this convection. Patchy fog is likely in the Susitna
Valley late tonight as the moist ground combined with light winds
and breaks in the cloud cover will allow for radiational fog in
the valley.

A wave of upper level energy will move through the area Wednesday
afternoon. This will bring widespread rain and showers to
Southcentral. Since the flow aloft will be southerly with no
strong cold air advection, the chance for thunderstorms is
minimal on Wednesday. Turnagain Arm winds are expected to develop
Wednesday morning and continue through Thursday morning as this
wave moves through.

Rain will gradually taper to showers on Thursday from southwest to
northeast as the wave of upper level energy exits the area.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 through 3: Tuesday
afternoon through Friday afternoon)...

Lingering showers over the Bristol Bay area will continue this
afternoon before dissipating by the evening hours. An upper level
trough in place over the eastern Bering moves eastward Wednesday.
Several upper level waves will propagate from east to west across
the area Wednesday and Thursday, bringing increasing chances for
rain. Some scattered showers may develop along the coast on
Thursday, however the greatest chance for precipitation will be
along the foothills of the Alaska Range Wednesday into Thursday.
Improving conditions are expected by the end of the week as the
trough departs and a ridge of high pressure builds Friday afternoon.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 through 3:
Tuesday afternoon through Friday afternoon)...

An upper level trough in place west of the Pribilofs will drop
southward tonight keeping broken cloud cover and scattered showers
across much of the Aleutian Chain and eastern Bering. Westerly to
northwesterly flow is expected with occasional gusts through the
afternoon on Wednesday along the central and eastern Aleutians.
By Wednesday night this trough moves eastward and the next low
arrives over the western Aleutians early Thursday morning. At
this time, expecting small craft level winds with this low as it
gradually moves eastward. Additionally, overcast skies and rain
will spread across the Chain, reaching the central Aleutians by
early Friday. This low then retrogrades and moves westward late
Friday bringing another round of rain to the western Aleutians
before departing to the south by the early weekend.

&&

.MARINE (Days 3 through 5/Friday through Sunday)...

A low and its front wrapped over the Western Aleutians and Bering
moves into the North Pacific by Saturday morning. Confidence is
good for showers and small craft winds and waves to wrap the low
through Saturday. Confidence is also good for showers and
Easterly small craft winds with local gales to spread over the
Eastern Bering and Bristol Bay Sat and Sun.

Weak high pressure exits the Eastern Gulf for Sat. A North Pacific
low moves through the Western Gulf by Sun. With its front wrapping
the low and spreading across the Gulf, confidence is good for
widespread showers and gale force winds over the Gulf diminishing
to small craft by Sun.

&&

.LONG TERM FORECAST (Days 4 through 7/Saturday through Tuesday)...

Back to back lows will move out of the Pacific. The first one is
Saturday. The global models continue to ping into an amplified
pattern across the Pacific. The GFS/ECMWF/Canadian models continue
to show meridional flow into SW Alaska Sunday/Monday as another
mature system moves across the Aleutians into the eastern Bering.
This set up will bring modified tropical moisture into portions of
Alaska. This is a classic "Atmospheric River" (AR). This AR will
impact the Aleutians...SW AK...eastward to Prince William Sound
and Cordova. Also noteworthy are the extratropical transitions of
Typhoon Maysak and then Tropical Storm Haishen from the West
Pacific Basin.
