Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
447 PM AKDT Sat Apr 10 2021

.ANALYSIS AND UPPER LEVELS...

Polar high pressure over the Yukon is retreating eastward as a low
over the Bering spreads cloud cover over Southcentral, and
precipitation across Southwest Alaska. The low is drawing much
warmer air northward into Alaska, which is ending the record cold
temperatures across the state. Light snow has ended over Bristol
Bay, while the snow is ending across the Kuskokwim. The
strengthening April sun is warming most areas into the teens and
20s, despite the increasing cloud cover.

In the upper levels, upper level ridging is amplifying over
Southwest Alaska and the AKPEN, with an upper level low and trough
to the west over the central and western Bering. Therefore, the
ridging is bringing much warmer air and cloud cover into the
area.

&&

.MODEL DISCUSSION...

Model agreement is good through Monday afternoon. The primary
areas of uncertainty include how quickly any snow transitions to
rain, and whether any freezing rain will occur in between,
especially across interior Bristol Bay. Over Southcentral, the
wind gusts with the upcoming storm may get close to warning
criteria on the ridges as the winds flip to southeasterly and
intensify Sunday and Sunday night. For now, while the winds will
be strong along the Hillside, enough northerly flow should keep
the Turnagain Arm wind aimed out into the Inlet or over the rural
Kenai Peninsula. This should inhibit winds from getting as strong
along the Hillside. Otherwise, temperatures are also in question,
as the warmest temperatures will be associated with the
downsloping and the Turnagain Arm winds. Overall forecast
confidence is moderate.

&&

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

&&

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

This morning, the minimum temperature at Ted Stevens Intl Airport
was 4F breaking the daily min temperature from 1985. (The NWS
office near the airport was zero degrees and Campbell Creek in
east Anchorage bottomed at 8 below zero). On Sunday, Anchorage
will get into the 30s with 40s expected for Monday and Tuesday.

The upper trough that has been over the eastern Bering has
multiple strong shortwaves pin wheeling around it and several of
them are advancing towards Southcentral. On satellite imagery the
leading edge of the surface warm front is near Kodiak today and
there is a fetch of modified tropical air associated with this
system. The front will progress eastward across the western Gulf
Sunday through Sunday night, then becoming quasi-stationary. With
the ridge to the east, this system will have the opportunity to
pump moisture. Expect widespread moderate to heavy precipitation
from Kodiak Island to Prince William Sound. Because of the upper
level wind direction, expect downsloping off the Chugach Mountains.
This downsloping will create a "rain shadow" for Anchorage and
the Matanuska Valley.

&&

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

More snow is expected over much of Southwest Alaska except for
Bristol Bay which will receive rain/snow mix through the forecast
period. An upper low over the Bering will continue to be the main
weather producer, while isolated shortwaves riding along the upper
level troughs will enhance increased snowfall and sky cover especially
across the Kuskokwim Coast and Delta through the next few days.
The frontal boundary from the upper low is still on-track to move
across the region through Sunday, therefore, anticipate a cold
winter pattern to continue into Tuesday.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Tonight through Tuesday)...

The aforementioned upper low over the central Bering will have
minimal effect for the Bering Sea except for a continuous snowy
pattern through the next few days. The onset of the next Northwest
Pacific low arriving near the western Aleutians by Monday night
will gradually elevate winds and seas west of Dutch Harbor. The
P-type for the Aleutians is mostly snow with a brief brush of
rain/snow mix between the western and central Aleutians in
response to the next Pacific low.

&&

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

Bering: An elongated area of low pressure with two centers moves
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 support 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 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.
