Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
454 AM AKDT Thu Jul 15 2021

.ANALYSIS AND UPPER LEVELS...
The upper levels feature a high over the northern Bering with a
low near the western Aleutians and another low moving south of the
Gulf. This is allowing northerly flow across much of the interior
into Southcentral with a couple of shortwaves which will produce
convection today. Satellite shows mid and high level clouds across
most of Southcentral. While Southwest Alaska has some areas of
fog and stratus moving into the Kuskokwim Delta and Bristol Bay.
The Bering is covered in low clouds with areas of fog and stratus
especially from Cold Bay and along the northern AKPen coast and
across the western Aleutians. Radar is clear across the area with
Fairbanks radar showing showers moving along the northern Alaskan
Range.

.MODEL DISCUSSION...
Models are in good agreement with the major synoptic features, but
some differences in the small scale details. Two shortwaves will
move south across Southcentral. The first this morning and the
second tonight, models in good agreement with isolated convection
developing ahead of the second shortwave this afternoon. The
biggest challenge for the short term will be the Saturday
afternoon/evening thunderstorm forecast as models are advertising
very warm low level air and fairly good instability with CAPE near
a 1000 or better. With the ridge overhead there will be strong
subsidence and a CAP in place. Models do advertise a weak
shortwave skirting Southcentral which may bring enough cooler air
aloft and energy to break the CAP and produce thunderstorms which
typically in these type of events produce a lot of lightning.
However, uncertainty among models on storm coverage. Right now NAM
shows isolated storm activity while the GFS is much more robust
with the convection. So lower confidence in thunderstorm forecast
for Saturday, stay tuned as we refine the forecast. Otherwise
models in good agreement with low pressure moving across the
western Bering and high pressure persisting across the eastern
Bering through the short term.

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3/Today
through Saturday night)...
A strong upper level ridge of high pressure over western Alaska
will build eastward over Southcentral today through Friday, then
persist through the weekend. Strengthening subsidence combined
with persistent northerly (offshore flow) will both contribute
to steady warming of the airmass. Expect some of the hottest
temperatures of the summer Friday through Sunday, topping out
in the lower to mid 80s over interior Southcentral. Coastal
locations will warm up as well, just not as significantly as
inland. Periods of stronger offshore flow will delay sea breezes
on some days. However, generally expect robust sea breezes to
develop each afternoon.

There is quite a bit of cloud cover remaining over Southcentral
this morning, but expect decreasing clouds today through tonight
as the ridge builds toward Southcentral and pushes short-waves off
to the south and east. There are a couple short-waves which will
transit the region today, leading to isolated to scattered
convection, primarily over the Copper River Basin. A weak wave
will track southward across the Talkeetna Mountains, so any
storms that form would track south in the vicinity of Palmer,
and possibly as far south as Eagle River this evening.

Subsidence looks particularly strong on Friday, so expect a
mostly sunny and dry day region wide. For Saturday, instability
parameters look quite impressive due to the continued warming of
the low level atmosphere. A spoke of the ridge will be transiting
Southcentral. The exact location of this ridge axis during peak
heating will determine where convective inhibition is strongest
and where convection might be able to pop up. Right now, it looks
like the most likely area to see isolated thunderstorms will be
the Mat-Su eastward across the Talkeetna Mountains, as the ridge
axis exits south and east during the evening hours. Assuming a few
storms do form, would expect abundant lightning and locally heavy
rainfall based on the amount of instability.

&&

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

Stagnant weather pattern persists as strong upper level ridging
continues to dominate over Southwest Alaska. Conditions under the
ridge remain mostly sunny, dry, and warm, with the warmest
temperatures ranging from the mid- to-upper 70's further inland
across the Kuskokwim Valley. Cloud cover rolls back in starting
out west over the Kuskokwim Delta and then making its way east,
by late Friday night as the ridge slowly starts to weaken.

&&

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

Patchy fog from the Pribilofs to the Southwest Coast is likely
under the high pressure ridge aloft. At the same time, areas of
dense fog are expected across the western Bering through the
remainder of the morning until a front extending off a Kamchatka
low pushes into the western Bering this afternoon. Winds increase
to small craft as the front moves across the Bering. Anticipate periods
of moderate to heavy rainfall to accompany the front today and
tonight across the Western Aleutians and western Bering with a
brief break in precipitation on Thursday. A second front enters
the western Bering by Friday night, bringing another round of rain
showers to the aforementioned areas.

&&

.MARINE (Days 3 through 5:Saturday through Monday)...

Expect winds less than 35 kts and seas less than 20 ft for the
Day 3 through 5 period. Low pressure continuing in the Bering Sea
will create some small craft advisory winds, especially through
gaps and passes in the Aleutians.

&&

.LONG TERM FORECAST (Days 3 through 7: Saturday through Wednesday)...

Models start the long term in solid agreement of upper level
ridging over Mainland AK and troughing over the Bering. This means
continued fair weather and warm temperatures through the weekend
for Southcentral. The Bering and Aleutians will keep active
weather with clouds and rainy conditions. Southwest Alaska is
caught in the middle, but ridging and fair weather should still
predominate Saturday before rain moves in Sunday.

Moving into next week, model agreement lessens but all still point
the upper level ridge weakening and pushing to the Southeast. This
will allow for troughing to become the dominant feature for all of
our forecast area, with a bit more of a zonal nature to the flow
as well. This means a likely return to cooler, wetter conditions
for the middle of next week for Southcentral. So, a persistent
weather pattern through midweek with moderate to high confidence
of a return to more active weather conditions.
