What forecasters said that day
The local office's own words before this storm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Anchorage, AK wrote its last area forecast discussion before this storm warning went out at Dec 25, 7:40 AM AKST, 8 hours 14 minutes earlier.
Area forecast discussion, Dec 25, 7:40 AM AKST, 8 hours 14 minutes before
Southcentral and Southwest Alaska Forecast Discussion...CORRECTED
National Weather Service Anchorage AK
740 AM AKST Wed Dec 25 2019
.ANALYSIS AND UPPER LEVELS...
The upper level trough responsible for the Christmas Eve snow in
Southcentral AK has lifted to the northeast. Snow continues in the
Mat-Su behind it, but has cleared from the Anchorage Bowl. Heavy
snow showers continue to impact the coast east of Prince William
Sound as well. The major player in the weather right now is the low
pressure system currently skirting past the eastern Aleutians and on
the door step of the Gulf of Alaska. It is reflected as a closed low
in the upper levels and as a mature occluded system at the surface.
There is also an upper level low in the Arctic, with troughing
extending down from the eastern north slope into Southwest AK. It
is this low that is feeding cold air into Southwest AK. In an
interesting turn of events, the low skirting past the eastern
Aleutians is aiding this cold air by drawing the trough south and
also enhancing wind speeds on the southwest coast and Aleutians.
&&
.MODEL DISCUSSION...
On the synoptic level models are in good agreement. The NAM
continues to have its own solution in resolving the low that moves
into the Gulf of Alaska later today. It starts out in step, but
then differences emerge tomorrow morning as the NAM places the
low center differently than other models. Fine scale differences
in models, mainly for Southcentral AK, will have impacts on the
forecast the next couple of days. Thus, we have high confidence in
the trend of active weather but low confidence for specific
weather features in the pattern.
&&
.AVIATION...
PANC...A brief break in the weather has allowed VFR conditions to
be present for the start of the 12Z TAF. However, the next weather
system is expected to move in this afternoon. It will bring more
snow, initially dropping category into MVFR conditions, then IFR
conditions overnight.
&&
.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
A triple point low center forms near Kodiak Island today then
moves just south of the Kenai Peninsula this afternoon then slowly
weakens over the north Gulf through Thursday. The associated
occluded front approaching Kodiak Island this morning moves to
the north Gulf coast this evening and weakens. Expect gale to
storm force winds with and in advance of this system. Snow
spreading over Kodiak will shift to a mixture of rain and snow
through the morning hours then should transition back to snow late
this afternoon as the low moves east. Strong westerly winds will
spread across the island as the low passes to the east and will
give rise to blowing snow. Snow spreads north onto the Kenai
Peninsula and North Gulf Coast through today and inland into
Southcentral this afternoon. Generally light snow amounts are
expected inland with heaviest snow potential over the eastern
Kenai Peninsula. Strong winds coinciding with falling snow will
significantly reduce visibilities this afternoon for the Kenai
Peninsula.
Tonight and Thursday...
Winds and snow should diminish across the western Kenai
Peninsula late tonight so the blowing snow threat will end.
Strong outflow winds are expected across the eastern Kenai
Peninsula through Thursday so expect blowing snow to continue at
least into the afternoon hours. Light snow will continue inland
into the afternoon hours. Perhaps a little heavier over the
Copper River Basin depending on where the deformation band sets
up. Widespread westerly gales are expected over the western and
central Gulf with storm force winds over the Barren Islands.
&&
.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
A Wind Chill Advisory remains in effect for the Kuskokwim Delta
through this early evening as a deep upper level trough persists
over the region. Wind chills of -50F are possible. Fair skies
will continue across much of the area through Thursday, with the
exception of a chance of snow today from Pilot Point eastward
through King Salmon and Iliamna as a large low pressure system
tracks south of the Alaska Peninsula.
&&
.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
A strong low south of the Aleutians continues to quickly track
eastward. Snow and blowing snow remain likely through mid-morning
over the eastern Aleutians and Alaska Peninsula. Relatively benign
conditions are expected across much of the Bering through the
remainder of the day. Two strong lows will develop south of the
Aleutians Thursday, bringing easterly gales and rain/snow to the
Chain, extending northward into the central Bering by Friday
morning.
&&
.MARINE (Days 3 through 5)...
(Friday through Sunday)
...Bering Sea and Aleutian Coastal Waters...
An active pattern is in store for the Aleutians coastal waters, with
multiple areas of low pressure affecting them. The first storm
stalls south of Amchitka on Friday, with another rapidly deepening
low tracking from well south of Cold Bay towards Kodiak Island.
These two storms act in concert to spread sustained gales across all
of the Aleutian chain and into the southern half of the Bering Sea.
Seas will be in the 15 to 20 feet range on the Bering Side and 20 to
25 feet on the Pacific side.
These winds and waves subside some for Saturday, before another
storm approaches the east central Aleutians from the Pacific,
while remaining well offshore. Northeasterly winds on the
backside of the low will spread sustain gales across all of the
Aleutian chain and the southern half of the Bering, with building to
near 20 feet across the southwestern Bering and west of Nikolski for
the Aleutians. Some sustain storm force winds may develop as well
for the east central Aleutians, depending on the track of the low
(how close to the coast does it get and how quickly does it deepen).
...Gulf of Alaska...
A trio of storms will move across the Gulf, with a storm on Friday
bringing widespread sustained gales to all of the Gulf, with perhaps
localized storm force winds as well. Seas of 15 to 20 feet may
develop for the outer waters. Then, a second storm moves in quickly
on its heels for Saturday, with sustain gales and a similar sea
state. A third storm again moves into the region, with high-end
sustained gales and perhaps sustained storms near the coast, with an
increasing sea state expected, perhaps in the 20 to 30 feet range
for the off shore waters and 15 to 20 feet closer to the coast.
&&
.LONG TERM FORECAST (Days 3 through 7)...
(Friday through Monday)
...Southcentral...
This looks to be possibly one of the most active patterns in many
years for the region, as the current model suite shows several
storms affecting the region in the extended period, and that's on
top of the first two moving through before it. These all will bring
multiple rounds of accumulating snowfall to all of Southcentral,
with some pretty impressive totals possible for some coastal
locations if the current model projections don't change (we all know
they usually do, as the further you go out in time, the more the
model variability increases).
An important feature to watch in later model runs is an unusually
strong mid-level polar low off the North Slope, that just sits
there while deepening to 477 dm. That in turn allows for a second
strong mid-level low on the order of 495 dm to take up residence
in the Bristol Bay region. These two systems then act in concert
to funnel very cold air from the Arctic into southwest Alaska,
with the Alaska Range keeping it just north and west of
Southcentral. This in turn allows for a third trough further south
in the north Pacific to feed off this funneling of colder air
aloft to help induce cyclogenesis (low pressure development), with
these storms intensifying as they track just along the baroclinic
zone aloft (just east of the trough axis), while the degree of
the cold air poised just north and west of the Alaska Range
prevents the storm track from moving further west or ingesting
warmer air from regions further south. This is because as the low
approaches, it does ingest colder air on the backside of each low,
as the air will be -30 deg. C at 850 mb (~4400 feet) across
southwest Alaska. This air modifies some, but stays cold enough to
allow any over-running precipitation to remain as snow.
So now on to the details. Our first storm (for the extended
period) moves from the north Pacific on Friday, to western Prince
William Sound Saturday morning. This storm will be in a deepening
phase, helping to draw abundant moisture northward.
Quickly on its heels is a second storm that moves from the
southwestern Gulf Saturday morning, to western Prince William Sound
by late Saturday evening, with more abundant moisture spreading
northward.
Then on Sunday, another fairly strong low moves from Kodiak
Island, to yep...you guessed it...western Prince William Sound
with a more pronounced precipitation shield ahead of it, due to a
stronger warm front aloft.
A fourth storm in a deepening phase will then track into the
Alaska Peninsula on Monday, with more over-running precipitation
moving into the region.
