Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
444 PM AKST Thu Dec 20 2018

.ANALYSIS AND UPPER LEVELS...

A broad negatively tilted trough is slowly lifting north across
Southcentral this afternoon. Heavy snow banding across portions of
the eastern Kenai Peninsula/Western Prince William Sound, which
brought a couple feet of snow, is heading north with the upper
trough and rapidly weakening. Stratus is evident across the
Anchorage Bowl, MAT-SU Valleys, and portions of the Copper River
Basin. The loss of mid level cloud cover (ice crystals) left a
shallow near surface layer composed of supercooled water drops
which fell out as freezing drizzle over locations around the
Anchorage Bowl. An occluded front was moving slowly north toward
Kodiak Island and the Alaska Peninsula. Snow and gusty easterly
winds were evident across the Alaska Peninsula, but snow and wind
had not worked into Kodiak yet.

Generally cold offshore flow kept most of the Southwest Mainland
on the dry side. Though Satellite imagery and observations
indicate a shallow layer of stratus and fog over the Delta. A
nearly stationary and weakening low was evident over the Central
Bering Sea. Snow showers and gusty westerly winds were evident
south as far as the central Aleutians.

&&

.MODEL DISCUSSION...
Model trends over the Gulf and Southcentral are in reasonably
good synoptic agreement. They differ some in exact pressure center
placement, but all tend to carry similar timing of gales and QPF
with the low and front heading north Fri and Sat. All also show a
weakening trend Sat night and Sun. Model differences are a little
more pronounced over the Bering Sea and ALeutians but in general
synoptic agreement Will be leaning toward the NAM for Southcentral.
Out west will only use the NAM for the first 24 hours then
transition to the GFS for the remainder through Sunday.

&&

.AVIATION...
PANC...Ceilings will generally hold in the MVFR range through
tonight. There is also possibility of periods of lower IFR
ceilings.

&&

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

A weak surface low situated in Prince William Sound continues to
produce bands of snow showers from Cordova to Whittier to Chenega
this evening. Snow shower activity will begin to wind down
overnight as both this feature and the east-west oriented upper-
level trough lift to the north. This lull will be short-lived,
however, as the next shortwave slides east into the western Gulf
overnight tonight into Friday. A front associated with the
surface low positioned in the southern Gulf will swing another
band of precipitation across Kodiak Island tonight and across the
southcentral mainland coast tomorrow. Precipitation with this
system will continue through Friday night and start as snow before
warmer air advecting south to north gradually turns the snow to
rain along the coast Friday. Chances of snow will move inland
during the day Friday, and continue Friday night as the colder air
inland remains in place. Another round of snow, with snow
changing to rain along the coast, will take place Saturday as the
surface low tracks north, closer to Kodiak Island, and another
shortwave advances to the southcentral coast. A strong
southeasterly component to the winds aloft should produce
downslope winds and limit perception along the lee of the Kenai
and Chugach Mountains with this system. Snow showers then linger
into Sunday as the surface low moves east and the upper-level
shortwave remains over the AKPEN.

&&

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

Northerly surface flow keeps a colder and drier pattern across
the Southwest through this weekend. Winds across the Kuskokwim
Delta and Valley will bring wind chill values between 20 to 40
degrees below zero. Temperatures across Bristol Bay will moderate
slightly warmer late Friday through the weekend as low level east
to southeasterly flow returns the influence of a maritime air mass.

&&

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

An active weather pattern continues across the southern and
western Bering through the weekend as three upper level low
pressure systems vie for dominance. The stronger surface lows are
expected across the western Aleutians with storm force winds
increasing around quickly deepening systems moving up from the
North Pacific. The first one moves up this evening crossing over
Shemya before taking a westerly turn towards the Kamchatka
Peninsula after midnight. The second moves up Friday afternoon and
follows a similar path. A cyclical pattern continues through the
weekend as an upper ridge forms between the North Pacific low and
and two other systems further east. Meanwhile, the occluded low
with a front over the eastern Aleutians and Alaska Peninsula
slowly fills as it tracks east through Saturday. This system will
bring increased chances for snow and rain showers across the
Peninsula as it stalls through the weekend.

&&

.LONG TERM FORECAST (Days 4 through 7)...

At the onset of the forecast period there are a series of surface
lows from the Gulf of Alaska to the North Pacific. The first low
is over Prince William Sound and the northern portion of the Gulf
of Alaska which is well into the decay process. Even though its
weakening, expect moisture to get steered into South Central with
this feature. There is a second surface low south of the Central
Aleutians with a third cyclone southwest of Attu Island. There is
a dome of high pressure over the Arctic Ocean with ridging
spanning across the Chukchi Sea and into the Bering Sea. At 12z
Monday, the global deterministic models all show these features.
As time elapses, the unsettledness continues south of the Aleutian
chain although the tracks of the surface lows deviates. The GFS
and the ECMWF bring a relatively organized low into the Gulf of
Alaska Christmas night, and this low will wrap another batch of
moisture into the Kenai Peninsula and Prince William Sound. Beyond
Dec 26th, there is simply too much model divergence to say
anything worth banking on.
