Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
528 PM AKST Wed Dec 6 2017

.ANALYSIS AND UPPER LEVELS...

The high amplitude pattern continues with a ridge over the
Southeast and a broad trough over the Bering. The next low of
concern is spinning south of the Alaska Peninsula with abundant
moisture streaming across the gulf and through the Copper River
Basin. At the surface, rain is developing across the northeast
gulf waters along a boundary that is shifting east, with snow
moving inland as warm moist air advects along southerly flow.
Impressive snow amounted across Thompson Pass today with 40" or more
inches observed from the SNOTEL stations and 12" inches across
Valdez observed during morning observations.

&&

.MODEL DISCUSSION...
Models are in relatively good agreement with the synoptic pattern
with slight differences in the track of the next low approaching
the Alaska Peninsula Thursday morning. The grids were updated
with use of the GFS for the Southwest mainland initially going to
a blended approach for Friday while higher resolution models of
the NAM were used for the Gulf and Southcentral.

&&

.AVIATION...
PANC...Localized fog will be in the vicinity of the airport late
this afternoon through early evening. However, strengthening
northerlies from 06z onward along with increasing clouds from the
east should help kick out the fog. Patchy light precipitation will
be in the area tomorrow, and all indications are it would fall as
freezing rain. The surface temperature may rise above freezing
during the afternoon with precipitation continuing in the form of
rain.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
A strong upper level trough over the Pacific will continue to
send a deep moisture plume north into the Gulf of Alaska. The
heavy precipitation shield has transited east through the day
today but is expected to reorient itself back to the west as the
supporting upper level jet takes a more westward jive tomorrow.
This means the atmospheric river will move back over the Prince
William Sound bringing another round of heavy precipitation to
the Valdez and Thompson Pass areas. Even more warm air is expected
to surge north so snow levels should rise to nearly 2500 ft in
the afternoon. In lower elevation spots, including Valdez,
precipitation will start out as snow with surface temps at or
below freezing, but warm air aloft will likely lead to a period of
freezing rain which will transition over to all rain by the
afternoon. Total snowfall at Thompson Pass is expected to be in
the 1.5-2.5 ft range through Friday afternoon. The Copper River
Basin is also expected to see a mix of precipitation tomorrow,
with snow changing to freezing rain to all rain for lower
elevations with mostly all snow for higher elevation spots.

Further west, a surface low will move north over Kodiak tomorrow
which should lead to stronger SE'ly winds through the gaps and
some downsloping. This will initially cut off precipitation for
the populated areas but as the low moves north precipitation will
spread up the Cook Inlet bringing rain, with the chance of some
freezing rain mixing in initially, late in the morning from the
Western Kenai Peninsula north into Anchorage and the Mat-Su Valley.
Precipitation will likely stay as all snow in the Western Susitna
Valley tomorrow, leading to 4-8 inches for the foothills of the
Alaska Range including Skwentna.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
A short-wave ridge is currently progressing from south to north
across the region, and this will continue to provide drier
conditions to Southwest Alaska for the next 18 to 24 hours. The
exception to this will be from Nunivak Island inland towards
Russian Mission, as locations north and west of this line will
continue to see a few snow showers through at least the evening as
they are grazed by a cold front lifting northeastward from the
northern Bering Sea towards Norton Sound.

The next player in our weather will be an area of low pressure
currently located well south of the AKpen. This low will lift
northward across the the peninsula into Bristol Bay for the
Thursday through Friday afternoon time frame. It's associated
occluded front will enter the area Thursday before undergoing
frontolysis during the evening. Some semblance of the front,
likely in the form of an inverted trough, will continue to rotate
across the region from east to west on Friday while the low
dissolves across the bay. Either of these features will bring
periods of light to occasionally moderate precipitation, with snow
being the predominant precipitation type based on point soundings.
However, some warmer air will advect northward as the system
approaches, with locations south of a King Salmon to Port
Alsworth line warming enough to see an eventual changeover to
either a mix of rain and snow or all rain for Thursday evening
onward. The same holds true for the Akpen during this time. The
active weather pattern looks to hold as we head into the weekend.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
A well-organized area of low pressure, on the order of 985 mb,
continues to trek east southeast while paralleling the central
Aleutians this afternoon, with its current position roughly 100
miles south of Amchitka. An associated warm front extends to the
northeast, with it being close enough for the overrunning
precipitation to reach the chain in the form of snow. The snowfall
has been rather intense at times, as a with a visibilities having
been reduced to 1/4 of a mile at times at Atka, and somewhat
higher values at Adak and Dutch Harbor. This trend will continue
through the evening, before precipitation becomes lighter and more
scattered as the low moves away.

Meanwhile, another area of low pressure will continue to wobble
across the western Bering through Friday morning while sending a
weak cold front south toward western portions of the chain. Snow
showers will persist across much of the bering and near the low,
with some enhanced coverage of precipitation likely along the
front as it approaches.

Finally, a third area of low pressure will lift up from the
northern Pacific into the AKpen in the Thursday through Friday
evening time frame, providing another round of widespread
precipitation from Cold Bay eastward. Here, snow will likely
change to a mix of rain and snow or all liquid precipitation as
warm air is drawn northward ahead of the system.

&&

.LONG TERM FORECAST (Days 3 through 7)...
The pattern will remain largely unchanged into the middle of next
week as a stout ridge persists over the west coast of the CONUS
and numerous systems track northward towards the Alaska mainland
in deep southerly flow. This means a continuation of warm
temperatures running well above seasonal normal values for much of
the southern mainland, with rainy conditions along the Gulf
coast and snow possibly mixing in at higher elevations. Many
inland locations will remain on the drier side due to fairly
persistent downslope flow, with only sporadic opportunities for
showers as various systems move through. The most noteworthy
system to monitor in the long term looks to be a deep low tracking
through the western Gulf Sunday night, bringing the potential for
very windy conditions to Anchorage and other favored locations
through Monday afternoon depending on how the system evolves.
Meanwhile, the Bering will also remain in an unsettled pattern
through next week, though no major systems are expected with the
