Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
350 PM AKST Thu Feb 15 2018

.ANALYSIS AND UPPER LEVELS...
The main feature is a low over the central Bering Sea with a
front extending southeast just off the Bering coast through the
Alaska Peninsula to a forming triple point southwest of the Gulf
of Alaska. There is an upper level trough across the eastern
Mainland into the Gulf of Alaska supporting a weak low over the
North Gulf Coast. This trough is rapidly exiting to the east, and
with it the snow over the Copper River Basin will end as the
trough clears the area. We have another low about 500 nm south of
the western Aleutians with the front in an arc just south of the
Aleutians. A 130 KT jet is running around the base of this low
then tapers off as it crosses into the flat ride. A 120 KT jet is
running along the front coming up from the North Pacific toward
the Gulf of Alaska. The triple point low development is evident in
the satellite imagery where the jet crosses the Bering low front
south of the Alaska Peninsula. It is also evident in association
with the low southwest of the western Aleutians where the triple
point low is forming south of Amchitka.

A more subtle feature is the weak ridging in the wake of the
trough exiting the eastern mainland. This will likely result is
localized fog issues this evening and tonight over Southcentral
Alaska into the Copper River Basin.

&&

.MODEL DISCUSSION...
The models have come into very good agreement in the short term
through Saturday. High pressure builds over the central and
eastern portions of the mainland and a more progressive and stormy
pattern is on tap for the Bering Sea and Aleutians. The models all
agree the triple point low will move toward Kodiak, but not push
inland, rather take an east southeast track across the Gulf of
Alaska toward Dixon Entrance. High pressure then persists over the
mainland, which would continue to deflect storms to the south
keeping the southern Mainland in a high and dry pattern into next
week.

&&

.AVIATION...
PANC...The main concern is the stratus and fog this evening.
Without strong signs of mixing it is rather uncertain whether the
stratus and fog will mix out at all this evening. Fog and stratus
is evident in the visible satellite imagery over the Susitna
Valley into Cook Inlet down to Augustine. It does appear the lower
atmosphere will dry sufficiently overnight tonight through early
Friday as low level outflow down the Susitna Valley and Cook
Inlet increases. Think this will be just enough to scour out
the fog and stratus.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
Dry conditions are expected across Southcentral as a ridge over
the central interior slowly breaks down through Friday morning.
This ridge is quickly replaced by another building ridge which
moves in from the west Friday night. Patchy fog is expected to
develop each night through the upcoming weekend across the typical
low lying areas as temperature inversions set up during the
night. Gusty offshore flow this evening across coastal gaps
tapers down overnight as the first ridge tracks from the central
interior to the Alcan border. The next building ridge, late
Friday, is expected to bring higher gusts as forcing from an
upper level wave moves from west to east.

Along the Kenai...A brief period of light snow is possible Friday
as a front moves across the west Gulf bringing wrap around
moisture along a surface low which develops early morning, then
moves off to the east during the afternoon. Another front moves
up from the southern Gulf on Sunday which brings increased chances
for snow and rain across all of the Kenai as it advances north
through the afternoon. Locations along and north of a line from
Kenai to Seward should stay all snow as mid level temperatures
cool.

Along the Gulf and Kodiak Island...a front moves in from the
Alaska Peninsula this evening spreading light rain and snow
through Friday morning. A triple point low develops just south of
Kodiak early Friday morning and tracks to the eastern Gulf waters
that afternoon. A brief dry period is expected Friday night
through Saturday as a surface ridge amplifies across the mainland
and Gulf. The next front is a weak system that races north from
the Pacific. This system, driven by a parent low over the Bering,
sends a warm front across Kodiak during the early morning hours on
Sunday. Precipitation may start as snow, then transition to all
rain as it lifts north to the Kenai and central Gulf around mid
morning.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 through 3)...
(Tonight through Sunday)
The active weather pattern looks to continue through the weekend.
Currently, another weak cold front is approaching the coast, with
area radars beginning to show the leading edge of precipitation.
Look for this front to continue pushing inland through the next 24
hours, with mainly snow being the dominant form north and east of
King Salmon, with more of a mix or rain showers heading down the
AKpen. Some gusty winds will develop for a few locations on the
coast, but coverage looked too limited to add blowing snow to the
forecast zones.

Otherwise, another short-wave ridge will build over the region for
the Friday night through Saturday time frame. Yet another front
will affect the area on Sunday, with winds and precipitation
potential rising once again.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 through 3)...
(Tonight through Sunday)
A series of low pressure systems will continue to affect the
region through the weekend. As one low exits the western Bering as
it moves north tonight, it's associated surface front will stall
near Atka, as another wave of low pressure ridges north along it
from the northern Pacific. This will reinforce rainfall chances
along much of the Aleutian chain. as the Pacific low continues
its northward trek through the Bering, the associated surface
front will sweep eastward through the remainder of the chain/AKpen.
Quickly following on its heals, storm number three will intensify
as a 975mb low develops west of Shemya on Sunday, with another
front arcing east and southward through the west central
Aleutians. Each front will bring an increase in precipitation
coverage and intensity, as well as increasing winds, most of which
will be gale to occasional storm force.

&&

.LONG TERM FORECAST (Days 3 through 7)...
The remnants of the front will push through Southcentral Alaska
Sunday night resulting in increased chances for snow. A low will
be over the north Gulf Coast, but as has been the theme of this
current pattern, this low will be deflected to the southeast by
the high pressure over the eastern mainland and Yukon Territory.
Out over the Bering Sea as one low is exiting to the northwest,
another is sliding north across the western Aleutians Sunday
night. The associated front pushes into the northern Bering Sea
arcing south across the eastern Aleutians. The warm front will
push northeast across southwest Alaska by Monday with the
potential for rain or a rain snow mix over southwest Alaska for
the early part of next week. The warm air is progged to push well
inland over the upper level ridge to the Brooks Range through
Tuesday and Wednesday, thus a continuation of this wetter and
warmer trend.
