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

.ANALYSIS AND UPPER LEVELS...

An upper level longwave trough remains anchored over the Bering
with a shortwave ridge over Southcentral. Underneath the trough a
complex low with multiple centers exists over the western Bering.
The primary front is well displaced from the low center and exists
over Southwest Alaska extending from Hooper Bay to King Salmon.
Blizzard conditions have been observed over the Kuskokwim Delta
Coast this morning with snow and blowing snow over Bristol Bay.
These conditions are expected to lift around sunrise.

Over Southcentral winds have by and large diminished across the
region with Valdez being the last to hold on to the cold drainage
winds. The polar shortwave that brought the cold air south can be
seen on infrared satellite over the Yukon Territory. Cold
temperatures remain in place underneath the shortwave ridge with
Anchorage International breaking another record low temperature
this morning at 6F. Temperatures in the Copper River Basin remain
well below average as well with Paxson measuring -29F and -17F in
Glennallen. Things should begin to warm today as upper level
clouds stream in from the west and southerly flow begins to set
in.

&&

.MODEL DISCUSSION...

Models are in good agreement in the short term but begin to
diverge on Monday. One minor difference in the short term is that
flow aloft is more zonal than models were depicting yesterday. As
a result, southwest flow over the Cook Inlet that may have lead to
an inch or two of snow has been decreased due to a stronger
westerly component and downsloping (drying) off of the Western
Alaska Range. On Monday, the primary model differences are in the
east/west location of the moisture field as it reaches the north
Gulf Coast. Minor Differences in the flow will lead to substantial
differences in snow totals from Whittier to Cordova. As such,
forecast confidence for these areas decreases on Monday.

&&

.AVIATION...
PANC...VFR ceilings and visibility will persist through the
forecast period. There is a chance for a brief period of light
snow this afternoon, but the atmosphere may remain to dry for
accumulation at the surface. Ceilings will likely hover around
5000 ft at this time before raising in the evening. Sunday
morning a front will move over the area, allowing for low level
wind shear and the typical downslope hole over the terminal.

&&

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

Amplifying upper level flow will result in an active weather
pattern for Southcentral and the Gulf over the next few days. Some
of the highlights include warming temperatures, chinook "downslope"
winds, and heavy precipitation along the coast. First off,
lingering strong winds in eastern Prince William Sound (including
Valdez) will finally die down during the morning hours as a
short-wave ridge moves overhead and pressure gradients rapidly
slacken. A short-wave trough over Southwest Alaska will weaken as
it crosses Southcentral today. With such a dry airmass in place
(Total Precipitable Water of 0.08" on the 12Z Anchorage sounding)
it's going to be difficult to saturate the low levels and get
snow all the way to the ground. Have backed off the snow forecast,
which was already unimpressive. Expect most areas to remain dry,
with the best likelihood of light snow/dusting along the west side
of the Kenai and Chugach Mountains.

Attention will shift to a much more impressive upper trough and
surface front approaching the western Gulf/Kodiak Island late
tonight. A series of short-waves will dig southward across the
North Pacific today/tonight causing rapidly building heights
across the Gulf and Southcentral. This will lead to development of
a strong southerly jet and atmospheric river, which is fairly rare
for this time of year. The front will progress eastward across
the western Gulf Sunday through Sunday night, then stall over the
central Gulf along the west side of the upper level ridge. Expect
widespread wind and moderate to heavy precipitation from Kodiak
Island to Prince William Sound. Strong low level southeasterly
flow will particularly favor the eastern Kenai Peninsula/western
Prince William Sound for heavy precipitation, while producing
downslope drying for most of the western Kenai Peninsula as well
as for Anchorage and the Matanuska Valley. Although the airmass
will certainly warm from its current state, expect the bulk of
precipitation to fall in the form of snow. Gusty winds will cause
surface temperatures to rise above freezing at sea level by
Sunday afternoon, with locations along the immediate coast likely
transitioning to a mix of rain/snow or even all rain. Snow levels
will remain low though, with coastal mountains getting a dump of
heavy snow to go along with the strong winds.

In addition to the strong low level flow, also expect gap winds
to develop on Sunday, most notably through Turnagain Arm, the
Knik River Valley, and along the Copper River. Expect temperatures
to jump where the wind is blowing, likely into the lower 40s.
Wind sheltered areas will remain cooler. Winds along Turnagain Arm
could approach High Wind Warning levels (75mph). However, at this
point it looks like pressure gradients favor the Turnagain wind
bending southward down Cook Inlet which should keep winds below
warning level along the Anchorage Hillside. In any case, this will
be the strongest Turnagain winds in quite some time.

Forecast confidence drops Monday through Monday night due to
uncertainty in the position of the surface front as well as timing
of the next trough and surface low moving up from the Pacific.
However, based on the highly amplified pattern, expect strong
winds and heavy precipitation to remain a threat, particularly
along the coastal zone. This is also a warm pattern, so expect
temperatures to return to normal (or perhaps even above normal)
for this time of year.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Today through Monday)...

Blizzard conditions are presently occurring across the Kuskokwim
Delta coast and areas near Cape Newenham. Visibilities will
slightly improve as winds slowly diminish this morning over these
areas, however light snow and blowing snow will continue much of
today. A weak upper ridge will inhibit any precipitation farther
inland. A second front will approach the Southwest coast this
evening. Precipitation types are somewhat challenging, however
brief initial snow over the Kuskokwim Delta will give way to a
mix or rain overnight (for lower elevations) into Sunday in a deep
southerly flow. Easterly winds will develop near King Salmon late
this evening into early Sunday morning. This may lead to surface
temperatures briefly falling to at or below freezing while 950 mb
temperatures remain just above freezing. As such, periods of light
freezing rain are possible for this area, though impacts will be
minimal. Widespread rain/snow showers will continue through Sunday
as a broad low weakens in the eastern Bering. Warmer temperatures
will continue into Monday, with rain showers becoming more
scattered as the low becomes vertically stacked and further
weakens.

&&

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

A front will track across the Aleutians through Sunday morning
bringing moderate rain and gusty southeasterly winds to the Chain
and Pribilofs. A broad low will gradually weaken in the Bering
through Monday. As it moves farther north, the northerly flow
behind it will change precipitation from west to east from a mix
to all snow showers.

&&

.MARINE (Days 3 through 5: Monday through Wednesday)...

Bering Sea/Aleutians

A broad area of low pressure will remain centered over the northern
Bering Sea on Monday. Winds are expected to remain below gale
force with no high seas expected. Forecast confidence rapidly
decreases on Tuesday as guidance shows significant differences in
solutions with respect to a second potential low pressure system
moving eastward across the southern Bering Sea Tuesday and Wednesday.
Overall, forecast confidence is moderate to high for Monday and
very low for Tuesday and Wednesday.

Gulf of Alaska

A front over the northern Gulf of Alaska will result in gale
force southeasterly winds across the coastal waters of the north central
Gulf of Alaska. These gale force southeasterly winds will also
extend into Prince William Sound before easing Monday night. A low
pressure system is expected to approach the Gulf on Tuesday. A
front associated with this low will bring another round of
easterly gale force winds throughout the coastal waters.
Confidence in the intensity of these winds is low to moderate due
to different solutions in the placement and intensity of the low
center. Though, there is a moderate degree of consistency these
easterly winds will funnel along the coast and will be gale force.
Confidence increases on Wednesday as these winds will gradually
weaken. No high seas are expected during this period.

&&

.Long Term Forecast (Days 4 through 7: Tuesday through Friday)...

The pattern will be amplified as an upper level low moves over the
Bering Sea on Tuesday while upper level ridging extends across the
eastern Alaskan mainland near the AlCan border. This low will then
move southeastward into the North Pacific on Friday. There is good
ensemble agreement that onshore flow and higher precipitable water
values are expected Tuesday and Wednesday as a front associated with
this low moves across the northern Gulf of Alaska into Southcentral
Alaska. This will allow for an increased chance of rain along the
coast and snow in more inland locations such as Turnagain Pass Tuesday
night through Wednesday afternoon. Due to the prevailing flow being
southeasterly, it is likely the Anchorage Bowl will have cloudy skies,
though little or no precipitation due to downsloping off the Chugach
Mountains. The precipitation associated with this front will taper
off across Southcentral Alaska Wednesday afternoon and evening.
Teleconnections support broad upper level ridging across the
Bering Sea and Alaska mainland Thursday afternoon onward. Due to
the dynamics of the aforementioned upper level low, there is good
ensemble agreement of a Rex Block forming over the Alaska
mainland and Bering Sea being under the upper level ridge Thursday
and Friday. The significance of the Rex Block is the upper ridge
will become more pronounced and is likely to persist for a longer
period of time. This upper level ridge will allow for a moderation
of the cold airmass and allow for more sunshine than clouds across
the Alaska mainland.
