Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
500 AM AKST Sun Mar 7 2021

.ANALYSIS AND UPPER LEVELS...

In the upper levels, a negatively titled trough with a broad low
near the Kamchatka Peninsula and its impressive baroclinic front
extends from the Chukchi Sea to the western Pacific. Ahead of this
front, a low amplitude ridge of high pressure extends its axis
over parts of southwest Alaska, Bristol Bay, and south of the
central Aleutian Chain. Weak troughing sits over the Gulf, with a
weak disturbance south of Kodiak Island that is slowly phasing
with another stationary, potent low over the eastern Gulf. Latest
ASCAT pass (scatterometer wind) is capturing small craft to gale
force winds south of AKPEN to the western and central Gulf
associated with cold air advection of these two distinct synoptic
features. These winds are expected to slowly diminish today. At
the surface, a weakening meso-low is moving south of Middleton
Island and was responsible for light snow yesterday along coastal
areas near Cordova and the surrounding higher elevations as well.
Radar is picking up scattered light snow showers over the Y-K
Delta associated with a weak low near St. Lawrence Island and its
front that pushed into Coastal Southwest AK since late yesterday.
The nighttime microphysics shows low stratus/fog completely
blanketed over the southwest, AKPEN, and the eastern Aleutians.
Additionally, low level ash emissions from the Veniaminof Volcano
located north of Perryville was visible on satellite imagery
overnight. With prevailing northwesterly winds aloft, the small
ash plume was visible on satellite drifting southeast over the
coastal waters west of Chirikof Island. The volcano has been
fairly active over the past couple of days, but has quieted down
this morning.

&&

.MODEL DISCUSSION...

Overall, model guidance are in consolidated agreement with the
synoptic features for the short term and on track with an active
weather pattern taking shape over the Bering/Aleutians as well as
the Southern Mainland this weekend into early next week. The
minor discrepancy with the latest model solutions has to do with
the position, timing, and trajectory of a low expected to form
along a frontal boundary near the western Gulf and Kodiak Island
on Tuesday. Forecaster confidence remains moderate, with
subsequent model runs hopefully ironing out some of these small
scale discrepancies and the resultant weather that will have over
the Southcentral coast.

&&

.AVIATION...
PANC...VFR with light winds today, tonight expect fog and stratus
to form and impact the airfield. IFR to LIFR conditions possible
from midnight through Monday morning.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 to 3: Tonight
through Tuesday)...

Outflow winds will continue through the day Sunday as a surface
ridge building over the interior and a trough over the northern
Gulf combine to increase the pressure gradient along the coast. A
weakening shortwave moving across Southcentral today will also
help enhance the gusty winds through favored gap locations
throughout the day. These winds will begin to wind down, first
over the Kenai and western Prince William Sound, this evening and
across eastern Prince William Sound and the Copper River Delta by
Early Monday morning as an upper level ridge builds in, ushering
in warmer air aloft as well as a southwesterly flow.

Fog will be the biggest forecast challenge through Monday morning.
Patchy fog may develop early this morning along Cook Inlet, but
conditions will be more favorable for fog development overnight
Sunday into early Monday morning as the ridge crests overhead with
warmer air moving in aloft. Fog early Monday morning may expand
to include not only areas around Cook Inlet, but locations in the
Mat-Su Valleys and Copper River Basin. Fog may also develop along
the immediate coast, especially near Cordova and Valdez.

By late Monday, the weather pattern will change and become more
active as a front moves east toward Southcentral. A low is
expected to form along the front Monday night somewhere north of
Kodiak Island and track into the northern Gulf toward Prince
William Sound for Tuesday. A deep southerly fetch of warm, moist
air will accompany this system, with the warmer air likely
allowing for snow to change to a rain/snow mix or even all rain
along the immediate coast. For interior locations, enough cold air
is expected to remain in place for the precipitation to fall as
all snow. With the flow aloft south to southwest, the highest
precipitation totals are expected along the coastal mountains as
well as the northern half of the Susitna Valley, including
Talkeetna and Broad Pass, as well as Hatcher Pass. A cross-
barrier flow may keep precipitation at bay initially for the
western Kenai Peninsula and Anchorage Bowl. However, accumulating
snow is possible by Tuesday afternoon as the low continues its
northeasterly track toward Prince William Sound and the cross-
barrier flow weakens.

&&
.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 through 2: Today
through Monday night)...

The P-type and the potential for blowing snow are today's
forecast challenges for the next frontal system approaching
Mainland Southwest specifically along the Kuskokwim Bay and
Kuskokwim Delta this evening into Monday morning. Though MOS
guidance favors snow and blowing snow conditions over Kuskokwim
Delta, warm southwest winds advecting inland tells a different
story favoring rain than dry snow ahead of the front. At mid to
upper-levels, strong winds could also reduce or eliminate the
potential for blowing snow.

The front's forward motion hasn't been promising and remained a
struggle for this forecast package. Its delayed motion led to
updating winds, sky cover, QPF, and POP grids to reflect the
latest situation. Cold air advection trailing behind the cold
front will begin to fill Y-K Delta Coast as soon the front passes
Nunivak Island Monday morning, causing temperatures to decline
into Monday night. Over Bristol Bay, rain/snow mix is expected
there, and mainly rain for AKPEN as warmer temperatures linger
there through the forecast period. Overall, the expected front
will be the main weather producer for the region. Stay tuned!

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 through 2:
Today through Monday night)...

The infamous front off an Arctic low will move across the Bering
Sea and Aleutians through this evening. A push of warm air out
ahead of the front will increase temperatures across the Aleutian
Chain enough for precipitation to be rain or a rain/snow mix.
Moderate to heavy precipitation is expected along the eastern
Aleutians and southern AKPEN as the front passes. Weak low
pressure remains behind the front as well as persistent westerly
flow. Winds should also diminish behind the front, becoming mostly
small craft along the Aleutian Coasts.

&&

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

Bering: An Eastern Bering front moves into Western Alaska Tue
night. Forecast tracks vary somewhat, but confidence is good.
Areas of small craft winds and waves dissipates Wed. Seas to 12
feet, subsiding. Several troughs cross the Bering through Thu,
with winds less than small craft level. A new low and front moves
into the Western Bering for Wed night and Thu. Widespread
increasing gale force winds move across the Western Bering. Seas
building to 16 feet Thu.

Gulf of Alaska: A low and front move across the Gulf for Thu.
Forecast tracks vary somewhat, but confidence is good. Widespread
southerly small craft winds and waves move across the Gulf for
late Tue, becoming widespread westerly small craft winds with an
area of gale force winds from the Barren Islands into the Northern
Gulf for Wed. Winds diminish Thu over the Northern Gulf. Seas to
12 feet, subsiding Wed.

&&

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

An analysis of long term guidance leads us to have moderate
confidence that we can expect changing weather conditions for the
Bering and Gulf of Alaska, while mainland AK stays quiet with
cold overnight temperatures through the week.

Wednesday, on the synoptic scale, longwave troughing will
generally encompass our forecast area. A high amplitude ridge is
exiting to the east and over the Yukon, while a low amplitude
ridge is moving into the far Western Bering. On the surface,
models are indicating a compact low skirting along the north side
of the Aleutians in the Bristol Bay area. Low pressure is also
lingering in the Prince William Sound area. The rest of the
forecast area looks to be quiet and under high pressure. This
means cooler overnight lows continue for mainland AK.

Going forward through late next week, in the upper levels models
are showing the low amplitude ridge in the Western Bering moving
east and building over Western AK. Troughing re-emerges over the
Western Bering and over mainland AK south into the Gulf of Alaska.
On the surface high pressure holds on in Mainland AK and Eastern
Bering, though models are teasing a surface low moving into the
West Coast. Low pressure continues in the Gulf and Western Bering.
Models are having discrepancies in handling specific features, at
most hinting at what might happen. So for now, we are sticking to
identifying the general pattern, which the long range guidance
does have at least moderate agreement on.

...TRACE ASHFALL POSSIBLE IN THE VICINITY OF VENIAMINOF...

The Alaska Volcano Observatory has detected continued activity
and low level ash emission in webcam and satellite data from the
Veniaminof Volcano located near Chignik. Any ashfall near Chignik
and Castle Cape is expected to be of trace amounts.

Surface winds are expected to briefly be out of the west early
this afternoon gradually turn southerly by mid to late afternoon.
Any potential ashfall would be north and east volcano.
