What forecasters said that day

The local office's own words before this gale 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 gale warning went out at Mar 5, 4:49 AM AKST, 10 hours 42 minutes earlier.

Area forecast discussion, Mar 5, 4:49 AM AKST, 10 hours 42 minutes before
Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
449 AM AKST Sat Mar 5 2022

.ANALYSIS AND UPPER LEVELS...

An occluded low is lifting over the Western Aleutians this
morning, aided by a southerly 100+ knot upper level jet. A broad
front extends from the low to Shemya to Adak and south of the
Western Aleutians. Southeasterly gales have been observed over the
Western and Central Aleutians. Storm force winds and especially
storm force gusts are possible through Saturday afternoon as the
low continues northward. Southeast gales will be common on the
Bering side of the Aleutians while west to southwesterly gales
will be more common on the Pacific side. These higher winds will
be accompanied by 20+ foot seas and guidance suggests 30+ foot
seas may develop on the southwest side of the Rat Islands.

Ahead of the low the jetstream dives southward over the Eastern
Aleutians and into the upstream portion of an upper trough located
over the Alaska Peninsula and Bristol Bay. Downstream of the
trough a southwesterly 95 knot jet streak is overspreading Kodiak
toward the Kenai Peninsula. Several shortwave disturbances are
lifting out of the North Pacific within this southwesterly flow
and will overspread Southcentral throughout the day, possibly
phasing with the Alaska Peninsula/Bristol Bay trough as it
continues eastward.

Across Southcentral current precipitation is limited to the
northern Gulf and parts of Prince William Sound. However, overall
precipitation should expand in coverage throughout the day as the
combination of the upper level jet, phasing trough and shortwaves,
overspread Southcentral with increasing diffluence aloft. Over
Southwest precipitation will be more isolated and light with snow
noted over the Kuskokwim Delta from Hooper Bay into Bethel.

&&

.MODEL DISCUSSION...

Models are in good agreement with the synoptic pattern this
morning across the Bering with the strength and track of an upper
low over the Western Aleutians. Across Southcentral models resolve
an area of low pressure moving into Prince William Sound
reasonably well. However, some differences remain with respect to
mesoscale details at the surface. Namely, timing of precipitation
between models remains different depending on the model of choice.
Hi-res guidance and even the NAM and Gem Regional are the fastest
with precipitation departing the Anchorage Bowl by around 9z on
Sunday. The EC is a hair slower with precipitation ending a within
a few hours of hi-res models. Finally, the GFS is the slowest
solution and keeps snow falling across the Anchorage Bowl through
around 15z on Sunday morning. The slower solution of the GFS would
likely result in higher snow amounts for the Anchorage Bowl while
the faster solutions would see lighter amounts through Saturday
night. Aside from timing of precipitation across Southcentral, the
only other discrepancy is noted with the track of a North Pacific
low south of the Alaska Peninsula on Monday morning. The NAM is
slower and further east while the GFS, EC, and Canadian are faster
and further west, bringing the low near Sand Point early Monday
morning.

&&

.AVIATION...
PANC...Timing of Saturday's expected snow remains on track with
VFR conditions to precede the snow through roughly 15z. Confidence
is high that ceilings and visibility will steadily deteriorate
through midday as snow increases in coverage, with IFR conditions
anticipated into the evening hours. One uncertainty concerned the
potential for rain to mix in with snow should temperatures hover
just above freezing; however, PANC is already down to 32 degrees
and temperatures should fall further through the morning hours.
Otherwise, expect VFR conditions to return after dark and closer
to 06z as low pressure departs the region to the east.

&&

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

Today is the day with the biggest weather impacts and uncertainty
for the next few days. This is due to a surface low tracking
along the north Gulf coast as the upper level trough moves into
the region from the west. Precipitation is showing up an radar
along the north Gulf coast early this morning with rain being
predominant along the coast from Whittier eastward. The colder
air is moving in from the west and the biggest forecast challenge
is determining whether the temperatures in the Cook Inlet area
will remain cold enough to support snow all day or whether it will
mix with or turn to rain. Many times in a situation when
Anchorage has seen southeasterly winds and temperatures in the 40s
the day before this sort of set up, it is hard to cool down
enough for snow. What is a little different today is that there is
neither a south wind or temperatures well above freezing to the
south. Homer and Kenai both dropped below freezing overnight and
this is indicative of the airmass being cold enough to start as
snow for all of the Cook Inlet region this morning. Temperatures
will warm into the mid to upper 30s, but the cooling airmass aloft
should mainly keep precipitation snow except for the southern
Kenai Peninsula where Homer will likely mix with or turn all to
rain. However even there, the Homer bluff will likely remain
mostly snow though the day. That is the thinking for this forecast
package.

The northern Copper River Basin also has a winter weather
advisory out into Sunday morning. The main concern here is for
snow today and then some blowing snow overnight as the snowfall
lessens, but northerly winds pick up through the Alaska Range.

After today, the weather pattern will shift and high pressure will
build over Southcentral. This will clear out skies Sunday into
Monday with the only caveat that there could be areas of fog that
develop after the precipitation ends. This is always a
possibility, but there may be enough dry northwesterly flow moving
over the region to minimize this. This could become a forecast
challenge for Sunday and Monday.

&&

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

A weak low pressure system will continue to move across the
eastern Bering and towards Bristol Bay this morning. This system
will produce light snowfall in the area, but little to no
accumulation is expected. As the aforementioned low moves inland
and an upper-level tough passes over Southwest Alaska, shortwaves
will produce light snowfall over the Kuskokwim Delta early today.
However, little to no snow accumulations are expected with this
setup as well. A ridge of high pressure will push over the
Southwest tonight giving way to colder temperatures and clearer
conditions. With the ridge setting up over the Southwest, winds
becoming light and variable, and clearer skies, conditions become
favorable for fog to develop across the Kuskokwim Delta Sunday
night into Monday morning. The next weather producer will move
towards the Alaska Peninsula Sunday night. This low will begin to
increase winds and precipitation chances over the Alaska
Peninsula and Bristol Bay areas Monday.

&&

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

A storm force low and its associated front will move across the
western Aleutians and into the Bering this morning. The
aforementioned low and front will track north and weaken on
Sunday. With the front extending into the western and central
Bering, gales will be produced in these locations Saturday night
into Sunday as a result. Widespread precipitation will move
through the western Aleutians and into the central Aleutians as
the front tracks northeastward with the low. A quick transition of
snow to rain should be expected in these areas. A north Pacific
low will track towards the Alaska Peninsula Sunday night with
gales force winds near the Alaska Peninsula and eastern Aleutians.
Widespread rain showers will move through the Alaska Peninsula
Sunday night into Monday with the aforementioned low. However,
models are still having some uncertainty with this North Pacific
low, so precipitation location/timing and the strength of the
winds may change.

&&

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

Gulf of Alaska: A moderately strong North Pacific low moves over
Kodiak Island, as its front extends across the Gulf through
Wednesday. Forecast guidance is good. High end Northeast gales
stretch from the Northern Gulf around Kodiak and Barren Islands,
Shelikof Strait and the Alaska Peninsula Coast, diminishing. Seas
to 16 feet across the Southern Gulf, subsiding Tuesday. Areas of
gusty winds persist through Wednesday.

Bering Sea: A Northern Bering low continues into the Chukchi Sea
by Tuesday. A well developed low and front moves into the Bering
through Wednesday. Forecast guidance is good. Gusty Southerly
winds across the Northern Bering diminish. Seas in ice free waters
to 12 feet, subsiding. The wind wrapped Western Bering low and
front brings high end Southerly gales with areas of storm force
winds over the Aleutians and across the Bering, spreading into the
Central Bering for Wednesday, diminishing. Seas building to 30
feet in parts of the Western Aleutians and Bering by Tuesday,
subsiding Wednesday.

&&

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

The long term begins Tuesday with a continuation of an amplified
upper-level pattern. A large upper-level ridge dominates the
eastern Pacific and extends north along the Al-Can border. A
large upper-level trough remains situated over the western
Aleutians. By wednesday, the ridge is pushed south as a shortwave
trough ejects from the larger trough and moves toward
Southcentral. A second shortwave also drops south from the
northern Bering, allowing a trough to linger across the state
while the ridge reasserts itself over the eastern Pacific and
extends across the AKPen and into the eastern Bering. The long-
wave trough upstream becomes negatively tilted as a large upper-
level ridge builds over eastern Russia. Although models diverage
greatly through next week, they are all indicating the potential
for the establishment of a rex block, with the ridge centered near
the Bering Strait and a trough with multiple embedded shortwaves
positioned along the Aleutian Chain by the end of next week. As
for sensible weather, expected near normal temperatures through
the period with a chance for snow over the interior and a mix of
rain/snow along the coast Tuesday into Wednesday as the
aforementioned shortwaves coverage on Southcentral. Conditions
will remain unsettled across the Aleutians as a series of lows
rotates around the larger upper-level trough.
