Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
353 PM AKST Sat Dec 23 2017

.ANALYSIS AND UPPER LEVELS...
An upper negatively tilted long wave trough extends from eastern
Russia to over the northeastern Pacific. On the eastern flank is
a slowly retreating ridge extending north from the eastern Gulf to
along the Alcan boarder. A nearly stalled front, associated with
a strong low south of the Alaska Peninsula, extends from the
southeast Gulf to over Southwest Alaska. Moist southerly flow with
this feature has brought more than a couple inches of rain from
Kodiak Island to along the Alaska Peninsula. Strong easterly
winds, ahead of and with the frontal boundary, were observed from
the western Gulf, across Kodiak Island to over Southwest Alaska.
Satellite imagery shows a large area of open cell cumulus across
much of the western/central Bering Sea/Aleutians associated with
cold advection and deep atmospheric instability.

&&

.MODEL DISCUSSION...
Guidance are in great agreement with the progression of the Alaska
Peninsula surface low center for the next couple days as well as
the exiting of the upper level trough inland.

&&

.AVIATION...
PANC...VFR conditions and light winds will persist.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
A front along the central Gulf begins to slowly track north
tonight. Gusty winds are expected along the frontal boundary as it
moves to the coast, including coastal areas along the Cook Inlet
with a tighter pressure gradient favorable for northerly flow.
Winds generally taper down on Sunday when the surface low moving
the front fills on its path to Kodiak Island. The main
precipitation band is expected to make notable progress late
Sunday as the associated upper level wave advances over the Kenai
and central Gulf waters. The main challenges with this front are
snow accumulations and coverage. Downsloping due to southeasterly
flow previously looked like it would keep areas along west facing
slopes dry. However, the surface low rapidly fills which may
diminish winds enough to allow for at least trace amounts through
Christmas Day. Rain and snow will change over to all snow and
taper off quickly on its track north. Snow amounts in the
forecast were retained although higher amounts could occur if the
air mass cools faster than expected in areas that start out as rain.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
This forecast period, the longwave trough remains negatively
tilted spanning from NE Russia and bisecting the Alaska Peninsula
with a ridge over the interior and the Yukon Territory. The
synoptic pattern will continue to fuel unsettled weather and
robust southerly flow over southwest. Every surface low associated
with the longwave trough is decaying this forecast period but the
remnant moisture and pockets of instability will keep the threat
of showers in the area.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
The King Cove observation is reporting snow, reduced visibility,
and gusty winds and the potential for more wintry weather exists
for the adjacent areas. The low that is just sought of Sand Point
will slowly push northeastward and fill. As the weekend unfolds, a
new low will enter the domain, once again moving from the Western
Aleutians to the Central Aleutians and bringing another round of
gusty winds and wintry precipitation. locate

&&

.LONG TERM FORECAST (Days 3 through 7)...
Beginning the extended period forecast Monday evening, there will
be a weakening upper trough lifting northward along the Gulf
Coast and a weakening closed upper low over the central Aleutians.
These features are being met by an upper ridge building over the
eastern part of Alaska, as well as an amplifying ridge over the
western Bering/Aleutians. Rain and snow showers along the Gulf
Coast and northern parts of the southwest Mainland will taper off
slowly by Tuesday, as the trough moves inland and falls apart. By
that time, high latitude blocking in the vicinity of Eastern
Siberia and the Beaufort Sea will begin to exert a stronger
influence on the pattern, and as usual, this lends to lower
confidence and higher variability with the upper level wave
pattern after Thursday. With that said, surface high pressure will
effectively "block" the storm track away from Alaska and the
Bering Sea, so the weather pattern looks rather quiet and benign
with seasonable temperatures and what looks to be dry offshore
flow for most of Southern Alaska through mid-week. Further west,
there is a chance of a stronger system to impact much of the
Aleutians and southern Bering Thursday and into the weekend, along
with a leading front pushing through the southern Mainland and
Gulf over the weekend. However, there is very little model
agreement at this time with regards to this system, and
confidence in this solution remains low.
