Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
505 AM AKDT Sun Apr 11 2021

.ANALYSIS AND UPPER LEVELS...

An upper level ridge over much of the mainland is moving northeast
into Canada this morning. An upper level low is just offshore of
western Alaska with a trough extending from western Alaska west across
the Bering Sea. Snow continues across the Kuskokwim Delta this
morning, as temperatures begin to approach and exceed freezing.
Rain continues across the Aleutians as warmer temperatures are
brought north in between the upper level trough and ridge.
Southcentral remains fairly calm, with temperatures starting to
warm as the cold air retreats. A small band of snow showers
remains across the northern Gulf.

&&

.MODEL DISCUSSION...

Models remain in good agreement through Tuesday. The greatest
forecasting challenge will be precipitation type as snow
transitions to rain and the potential for freezing rain across
interior Bristol Bay during this timeframe.

&&

.AVIATION...

PANC...VFR conditions and light winds will persist. Strengthening
southeasterly winds aloft, over northerly winds near the surface,
have the potential to cause wind shear development during the day
on Sunday.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3/Today
through Tuesday night)...

A negatively tilted trough will swing into the western Gulf today,
pushing a frontal system north and east towards Southcentral. The
upper level pattern is highly amplified, with a strong southerly
jet and atmospheric river. As a result, expect lots of wind and
precipitation with this storm system. Moderate to heavy
precipitation will spread from Kodiak this morning to the north
Gulf coast and Prince William Sound this afternoon and evening.
Low-level southeasterly flow will strengthen throughout the day,
enhancing precipitation over the eastern Kenai Peninsula and
resulting in downslope drying for most of the western Kenai,
Anchorage and Matanuska Valley. A secondary area of upslope flow
and heavier precipitation will be along the west side of Cook
Inlet and the western Susitna Valley (along and near the Alaska
Range). Despite the southerly flow, the air mass over Southcentral
will remain cold enough to support all snow (with the exception
of the immediate coastline) as the frontal system occludes over
the Gulf.

The upper level trough will exit northward by Monday morning,
while the frontal system exits to the eastern Gulf. Additional
upper level waves combined with weak instability will lead to a
showery pattern Monday through Monday night. With a little bit of
wind everywhere, expect high temperatures on Monday to warm across
all of Southcentral, likely reaching 40 to 45 degrees for most
locations.

There remains some uncertainty in the forecast for Tuesday through
Tuesday night. However, it is looking more and more likely that a
deep low will move up from the Pacific and into the Gulf. While
we can't nail down the details of this system yet, this system
looks like it may be more significant than the current storm.
Specifically, the Gulf coast and Prince William Sound could see
multiple inches of (liquid) precipitation - which equates to
multiple feet of snow in the coastal mountains. Stay tuned as
we hone in on this storm and its impacts.

&&

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

An upper level low over the central Bering with multiple embedded
shortwaves and an associated front will traverse coastal
Southwest AK through Monday. A wintry mix of precipitation ahead
of the front will initially start over the Bristol Bay coast and
the AKPEN before transitioning to all snow. Meanwhile, with
strong, gusty winds, blowing snow will be a concern over the
Kuskokwim Delta coast, but is expected to improve over the next
few hours. As the front progresses eastward later tonight, moist,
southwesterly flow aloft will keep snow showers ongoing through
Monday in the aforementioned areas as well as the middle
Kuskokwim Valley and the surrounding high elevations.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Today and Monday)...

A front associated with a stationary low over the central Bering
is moving eastward and bringing a rain/snow mix over the
eastern Aleutian Chain. In the wake of the front, cold,
northwesterly winds and wrap around moisture on the backside of
the low will keep the threat of snow showers over much of the
Bering and Aleutians through Monday. Additionally, a shortwave
trough and associated low is expected to dive southeastward from
the western Pacific and bring another chance of strong winds and a
wintry mix of precipitation between the western and central
Aleutians by Monday afternoon.

&&

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

Bering: An elongated area of low pressure with two centers move
east across the Bering. Confidence is high with the northern low
to move inland over northwest Alaska by Wed. Confidence is mixed
with the southern low as upper-level support brings winds less
than gale force across the Aleutians and southern Bering through
Thu, with seas building to 16 feet around the Aleutians through
the forecast. A new system approaches the western Bering for Thu.

Gulf of Alaska: A front across the Northern Gulf brings easterly
gale force winds over north Gulf coastal waters for Tue and Wed.
Confidence is mixed on timing and strength between the front and
an approaching low that will track over Kodiak Island into the
Alaska Peninsula by Thu. This low spreads gale force winds over
the Gulf, with seas building to 18 feet east of Kodiak Island Wed,
subsiding after the low moves inland.

&&

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

The pattern will remain amplified as an upper level low is
expected to be over the North Pacific while upper level ridging
builds across the Bering Sea and Alaska mainland. The overall
synoptic pattern supports this upper ridge to remain in place and
become even more pronounced over both the Bering Sea and Alaska
mainland as Rex Blocking is likely. The significance of the Rex
Block is the upper ridge will remain in place for the majority of
the forecast period and become most pronounced toward the end of
the period. At the surface, there is good ensemble agreement with
the surface low associated with the aforementioned upper level low
to be located near Kodiak Wednesday morning with a warm front
moving across the northern Gulf of Alaska into Southcentral
Alaska. This will likely bring rain along the coast and snow in
the Chugach and Kenai Mountains as the southeasterly onshore flow
associated with the front will bring moisture to the area. The
snow may be heavy at times due to good ensemble agreement showing
precipitable water values at 2-3 standard deviations above
normal. The high precipitable water anomalies combined with
orographic lifting can result in moderate to heavy snow.
Precipitation will gradually taper off Wednesday night into
Thursday morning. The remainder of the forecast period will have
warmer temperatures, fairly dry conditions with more sun than
clouds as the upper level ridging becomes more pronounced across
the area. Due to good ensemble agreement on the surface and upper
level pattern, overall forecast confidence remains above average
for the extended period.
