Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
553 AM AKDT Sun Jun 6 2021

.ANALYSIS AND UPPER LEVELS...

Little evidence remains of the active weather day across
Southcentral on Saturday, aside from some lingering cloud debris
leftover from the previous afternoon's round of vigorous airmass
convection. This shower and thunderstorm activity was most
concentrated over the Mat-Su Valleys, western Chugach Mountains
and far northern Kenai Mountains on Saturday afternoon and
evening. Frequent lightning, gusty downdraft/outflow winds and
small hail up to 0.25 inches in diameter was reported with the
strongest cells as they rolled southwest across the Mat-Su Valleys.
With warm low level temperatures, residual boundary layer
moisture and ridging aloft across Southcentral remaining in
place, similar areas will be subject to the threat for renewed
thunderstorm activity later today.

Looking elsewhere and aloft, not much has changed with the larger
players in the synoptic pattern. An upper level low remains
stubbornly parked near the Bering Strait, which continues to
impart a cool onshore flow into the Y-K Delta. A broad ridge
continues to build into the western Bering, with a nearly
continuous mass of marine stratus spanning most of the Bering
underneath and just downstream of the upper ridging. The pressure
gradient between the low still sitting over the Bering Strait and
the aforementioned ridge is generating a corridor of enhanced
northeast winds across the central and northern Bering as well,
mostly of small craft strength or less.

&&

.MODEL DISCUSSION...

The most pertinent model discrepancies for the next couple days
continue to pertain to afternoon convective potential over
Southcentral. Models show a decrease in steering flow (from
850-700 mb) for this afternoon, suggesting storm motion will be
near zero with the lack of weak northeast flow that was in place
yesterday. With otherwise little change in the synoptic pattern,
the locations favored for convection during the previous two
afternoons should serve as a good proxy for determining the most
favored locations for thunderstorm initiation later today. This
would generally be across the Mat-Su Valleys and foothills of the
Talkeetna and Chugach Mountains, where convective parameters are
also maximized in most model output.

By midweek, the attention shifts to a pattern change that most
model solutions are fairly on board with. A westerly shortwave
traversing the southern Bering and Aleutians may weakly phase with
the upper level low still drifting near the Seward Peninsula by
Tuesday, with the shortwave then crossing into the Gulf by
Wednesday morning. There are some minor differences in the
progression of the wave across operational model solutions.
However, the net effect of bringing a cooler, showery and stable
pattern back to the southern mainland by Tuesday and Wednesday
will be about the same regardless.

&&

.AVIATION...
PANC...VFR conditions and light winds will mostly persist.
Similar to yesterday, a light, westerly sea breeze winds should
pick up this afternoon. Showers and a few thunderstorms will
likely again develop over the foothills of the Chugach Mountains
and across the Matanuska Valley late this afternoon and evening.
There is a slight possibility for a few of these showers/thunderstorms
to drift close to the terminal. That being said, very weak
steering for this activity should result in most of the
development sitting in place to the northeast, generally over/near
the mountains.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2: Today
through Monday)...

Southcentral is looking at the last day of the summer-like
pattern today as we begin to transition back to a wet-season
fall-like rainy pattern by Tuesday.

For today, expect nearly a carbon copy day as yesterday. Plentiful
morning sunshine will give way to showers and thunderstorms across
portions of Southcentral. The main area of thunderstorms will be
across the Susitna Valley, in much the same fashion as yesterday.
The only subtle differences today will be slightly more
instability, which could allow for storms to be stronger, and a
somewhat slower steering flow. This weaker flow means the storms
will move more slowly, which means fewer areas will be impacted,
but those areas that do see thunderstorm activity could get more
rain than if those storms impacted them yesterday. Scattered
thunderstorms are likely across the Susitna Valley today, and the
stronger storms could feature any or all of small hail, gusty
winds, frequent lightning, and heavy rain. Isolated thunderstorms
are likely once again today over the Chugach mountains east of
Palmer and Anchorage, and over the interior Kenai Mountains as
well. With relatively little thunderstorm activity yesterday over
the Copper River Basin, along with much more widespread cloud
cover, the chances of storms have been reduced a bit in that area.
Temperatures will once again top out well into the 70s for the
Mat-Su and east Anchorage, and near 70 in west Anchorage. Coastal
locations susceptible to the usual afternoon sea breezes will have
highs a bit cooler, mainly in the 60s.

On Monday, we will begin the transition back to a fall-like
pattern across Southcentral. A meandering upper low that has been
stuck near Nome for the past several days will finally begin to
move southeastward towards Southcentral. This will turn the upper
level flow southwesterly, bringing Gulf moisture straight up Cook
Inlet. Meanwhile, a small jet streak will enhance the lift
already being generated by the terrain. This means the northern
Susitna Valley will see sustained, stratiform rain and higher
elevation snow for much of the day Monday. South and east of these
areas, the last of the summer-pattern and the thermal trough will
remain, so isolated thunderstorms are possible again along the
Chugach mountains, and across the Copper River Basin, where the
thermal trough will move to on Monday from its current position
today over the Susitna Valley and Talkeetna Mountains.
Temperatures will be notably cooler for most areas west of the
Copper River Basin on Monday due to the increased cloud cover.
Some cross-barrier flow will allow for gusty southeasterly winds
off Turnagain Arm to move into south and west Anchorage Monday
afternoon and evening.

On Tuesday, a stronger upper level wave moving into Southwest
Alaska will set up a much longer southwesterly flow ahead of it
over Southcentral. The lift ahead of the disturbance with an even
stronger Gulf moisture feed will make for a truly fall-like
washout kind of day for much of Southcentral, with highs only
topping out in the mid-50s, overcast skies, and rain for most of
the day, with the thunderstorms of yesterday and today a distant
memory. The rain looks likely to continue through Wednesday,
though it may not be nearly as wet as Tuesday from Anchorage
north.

&&

.FIRE WEATHER...

Scattered thunderstorms are likely to develop once again this
afternoon and evening across the Susitna Valley. Any storms that
develop will be capable of producing small hail, gusty winds,
heavy rain, and frequent lightning. Meanwhile dry, warm, and
breezy northerly winds are expected this afternoon over the Copper
River Basin. This will reduce afternoon RH values below 25
percent. Gusts up to 15 mph are possible, with highs anywhere from
65 to 70 degrees, depending on how much sunshine gets through the
high level cloud cover currently over the area.

The fire weather threat will diminish Monday as more widespread
cloud cover moves the thunderstorm threat eastward into the Copper
River Basin, then returns to zero on Tuesday due to widespread
wetting rainfall.

&&

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

A vertically stacked low continues to spin over the Bering Strait
and is slowly pushing southeast. Unseasonably cold air at 850 mb
filters into the Kuskokwim Delta in behind the low, increasing the
chance for a rain/snow mix across the region. Flow is primarily
onshore (southwesterly) with this pattern. Thus, patchy fog is
likely to develop along the Coastal areas during the overnight
hours. Additionally, expect winds to be relatively gusty across
Bristol Bay and the Kuskokwim Delta.

&&

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

A negatively tilted ridge exists across the Bering through Monday
morning, getting forced southeast as a weak North Pacific surface
low pushes across the Aleutian Chain Monday afternoon through
Tuesday. This low carries a decent amount of moisture with it,
allowing for periods of moderate to heavy rain showers for the
Central/Eastern Aleutians and the Southern AKPen. Winds are not
expected to be excessive, but will result in small craft winds
south of the Aleutian Islands. Persistent southwesterly flow
across the Bering will allow for the development of some patchy
fog overnight across the eastern Bering as well as along the
Southwest Coast, Southern AKPen, and the Pribilof Islands.

&&

.MARINE (Days 3 through 5: Tuesday through Thursday)

A Western Alaska Peninsula low exits to the North Pacific late
Tuesday. High pressure spreads over the Bering by Thursday. Good
Model Agreement. Gustiest winds less than gale force extends from
the Northwest Bering into Bristol Bay through Thursday. High
pressure moves over the Gulf by Thursday. The Alaska Peninsula low
moves through the Western Gulf Wednesday. Gusty winds less than
gale force spread from the Shumagin Islands into the Gulf through
late Wednesday. Gusty Gap winds through The Barren Islands and
Shelikof Strait diminish Thursday.

&&

.LONG TERM (Days 4 through 7: Wednesday through Saturday)...

The extended forecast uncertainty still hinges around the upper
level low pressure currently spinning over the Bering Strait.
Models have come into better agreement by the beginning of the
extended forecast, bringing this feature over the Y-K Delta.
Expect a continuation of cooler and cloudier conditions early next
week for the Southwest Mainland. On Wednesday, a system/front from
the north Pacific will be making it's way into the Gulf of Alaska.
How the aforementioned systems interact with each other will have
a major bearing on the forecast. If the systems essentially
combine, it would be a change to cooler and wetter conditions even
inland over Southcentral. Either way that front has a decent
chance of impacting the north Gulf Coast, but more uncertain
inland. What happens late week after that is still not well agreed
upon at all, specifically what happens with the upper low pressure
system, which will have a big affect on what the longwave
pattern looks like.
