Southcentral and Southwest Alaska Forecast Discussion...CORRECTED
National Weather Service Anchorage AK
822 AM AKDT Mon Oct 5 2020

.ANALYSIS AND UPPER LEVELS...

Much of Mainland Alaska remains in generally weak synoptic flow
aloft as a weak upper level trough remains in place. As a result,
mostly clear to partly cloudy skies are being observed across the
Susitna Valley west into the Middle Kuskokwim Valley and Bristol
Bay. Just south of the Gulf Coast, however, are two closed upper
level centers with the one furthest east near Yakutat being the
stronger one. Its associated surface low continues to move toward
the coastline and then eventually will move inland. ASCAT
scatterometer data passed right over the center of the storm
showing solid gales (~40kts) on the south and west side of the
storm. A band of rain extends from western Prince William Sound
south into the offshore marine zones behind the low this morning.

Quiet conditions continue across the Bering Sea and the Aleutian
Chain this morning when looking at water vapor imagery, one can
see an upper level ridge building into the region. Also, looking
at the CIMSS MIMIC Precipitable Water imagery, you can see the
moisture feed from the tropical West Pacific beginning to be drawn
northward in association with the next storm system that will
impact the Bering Sea Monday through Tuesday.

&&

.MODEL DISCUSSION...

Model guidance remains in great agreement on the synoptic scale
features through Day 3. The main weather feature during this time
will be a low moving into the Bering in which all models agree on
the movement of this system. There still remain the very subtle
differences on timing but these are relatively minor. Beyond Day 3
is when the models diverge on the development of a triple point
low in the Gulf of Alaska. The EC remains the furthest south and
is the slowest with this feature, whereas the GFS and Canadian are
further north and faster with it. Therefore, confidence beyond day
3 is average.

&&

.AVIATION...

PANC...VFR conditions and light winds will persist.

&&

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

A gale force low sitting south of Cordova this morning will exit
eastward today. The occluded front will track north and west
across the Copper River Basin leading to areas of light rain (and
mountain snow). As the low exits into the Yukon tonight, a short-
wave trough which is currently stationary over the Talkeetna
Mountains will begin to track eastward across the Copper River
Basin, which will maintain areas of light precipitation. The
airmass will cool slightly, leading to slowly falling snow levels
and an increasing likelihood of seeing snow through the major road
passes. Meanwhile, tight pressure gradients across the Gulf and
low level instability will maintain gusty winds across much of the
Gulf coastal waters through Monday night, before diminishing on
Tuesday.

The western portion of Southcentral, from the Kenai Peninsula to
Anchorage and the Mat-Su will remain dry the next couple days,
with some sunshine and normal to slightly above normal temperatures.
One final weak upper trough will track from west to east across
Southcentral Tuesday night into Wednesday. This will lead to an
increase in clouds and a chance of light rain for the
aforementioned western portions of Southcentral. The trough will
interact with the surface low over the northern Gulf to enhance
rain/showers around Prince William Sound.

As we head to mid week attention will shift westward to a large
storm system over the Bering Sea. The leading front will reach
Kodiak and the western Gulf on Wednesday, with the upper trough
headed for Southcentral. Based on the orientation of the front,
the bulk of rain will be confined to the coast, with downslope
flow likely keeping much of interior Southcentral dry.

&&

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

Onshore flow will continue showers today over the Y-K Delta and
AKPEN to the west of Pilot Point. Cold, northerly air is expected
to move in from the west on the eastern side of a shortwave
ridge centered over the Bering. This will drop high temperatures
into the 40s over the Y-K Delta today. Evening lows are then
expected to drop into the 30s tonight across the region with snow
possible over the Kilbuck Mountains by Tuesday morning. Highs on
Tuesday should be the lowest for the week ranging from the upper
30s over the Y-K Delta and Middle Kuskokwim to mid 40s over
Bristol Bay and the AKPEN. The pattern will then transition back
to warm, rainy, and windy as a strong front moves in from the
Bering Tuesday night. A brief period of snow is possible prior to
the front over the Kilbuck Mountains and Middle Kuskokwim,
however a rapid transition to rain is expected as the front moves
through. Rain totals for the front range from 0.5 to 1.1 inches
by Thursday morning, with the higher totals favoring the northern
Bristol Bay coastline and windward (southeastern) side of the
Kilbuck Mountains.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 through 3)...

Mostly calm weather is expected on Monday morning due to a high
pressure ridge centered over the Bering. Scattered showers are
possible from the Pribilofs south to Dutch Harbor under the regime
of weak northerly flow. A strong front is then expected to move
into the western Bering Monday afternoon. Winds up to storm force
and heavy rain are possible tonight into Tuesday morning from
Shemya to Adak. The front should weaken on Tuesday as it continues
its path west with widespread gales and heavy rain. Behind the
front, cold air advection will bring another round of strong winds
and showers over the southern Bering and Aleutian Chain through
Thursday morning.

&&

.MARINE (Days 3 through 5/Wednesday through Friday)...

Bering/Aleutians

Early Wednesday a low will move into the northwestern Bering,
with its front stretched across the central Bering/Aleutians. Gale
force southerlies are expected ahead of the front across the
central/eastern Bering and Aleutians. Late Wednesday, this front
rapidly heads east of the Bering with winds turning west
southwesterly and decreasing to small craft advisory levels across
the region. For Thursday and Friday the low slowly weakens near
St. Matthew Island as winds across the Bering/Aleutians continue
westerly at small craft levels.

Gulf of Alaska

Light westerly flow is expected Wednesday. On Thursday, winds
will flip to southerly, with small craft level winds expected
across the western Gulf. On Friday, winds turn northerly and fall
below small craft levels.

&&

.LONG TERM FORECAST (Days 4 through 7/Thursday through Sunday)...

A broad upper level trough is expected to extend from the central
Bering through the Gulf of Alaska and Southcentral Thursday
through Sunday. Despite the low 500 mb heights, temperatures are
not expected to be much colder as there is minimal cold air
advection expected over Southcentral Alaska due to the center of
the upper low remaining over the Bering Sea. This will result in
prevailing south-southeasterly flow across Southcentral which will
help provide moisture to produce showers through the area. The
strongest cold air advection will occur west of the upper low over
the western Bering/Aleutians. This strong cold air advection is
likely to result in Ocean-Effect showers throughout the western
Bering/Aleutians.
