Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
420 PM AKDT Mon Oct 9 2017

.ANALYSIS AND UPPER LEVELS...
The main features today are: a southeast retreating low over the
eastern Gulf, building ridge extending northeast across the
Aleutian/western Alaska Range, and a weakening low over the Gulf
of Anadyr with trailing frontal trough over western Alaska/central
Bering sea. The pinch in pressure between the Gulf low and ridge
to west created very strong westerly/storm force winds across the
western Gulf and strong gap flows across the northern Gulf and
eastern Kenai Peninsula. Brisk to strong southwesterly winds,
associated with the front stretching west across the Bering Sea,
was evident across much of the Bering to over Southwest Alaska.
Widespread rain was also present along and in advance of the
frontal boundary.

&&

.MODEL DISCUSSION...
Models overall are in good synoptic agreement except for the
Canadian which is struggling with the low heading toward the
Bering Sea Tuesday night into Wednesday. The GFS will be used
overall out west. In the east, the higher resolution NamNest and
hand edits will be used for winds with the GFS for QPF.

&&

.AVIATION...

PANC...VFR conditions will prevail. Light winds today will give
way to gusty southerly winds Tuesday morning.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
A surface low currently over the Eastern Gulf will continue
drifting east out of the area as it dissipates tonight while an
upper level ridge will move east and center itself over
Southcentral. This will act to decrease the pressure gradient and
lead to diminishing gap winds throughout the night. A system over
the northwest coast will act to flatten the ridge tomorrow
bringing increased cloud cover, though weak forcing will limit
precipitation to the Alaskan Range as well as the Talkeetna
Mountains. Snow levels in the Talkeetnas will hoover around 3000
ft over the next couple of days so some minor snow accumulations
can be expected tomorrow afternoon into the following night for
Hatcher Pass. On Wednesday, the ridge briefly re-amplifies ahead
of the next system leading to pleasant weather for early October
with partly sunny skies and high temps approaching the 50 degree
mark across most of Southcentral.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
Deep onshore southwesterly flow will pump moisture into Southwest
Alaska over the next few days. A weakening front over the Upper
Kuskokwim Valley will continue to bring showers to the area
through this evening as the front stalls ahead of the Alaska
Range. Most of this precipitation is falling in the form of rain,
however a few areas are reporting some light snow. Temperatures
will warm this evening through tomorrow as warmer air moves in
behind the front, allowing any lingering snow in the Upper
Kuskokwim Valley to switch over to rain by this evening. As the
front weakens over the Alaska Range tonight, the leeward side of
the Kuskokwim Mountains will dry out Tuesday. On the other side of
the mountains however, the Lower Kuskokwim Valley will continue
to see an onslaught of precipitation until a weak ridge moves in
Tuesday night. The ridge will allow the Southwest Coast a brief
respite from the rain until the next front brings a return of rain
along with gusty winds by Wednesday afternoon.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
The Bering Sea will continue to see active weather through
midweek. As one low pressure system exits the northern Bering this
evening, the next system to impact the area will quickly move in
from the southwest Tuesday morning. This new low will move to the
western Aleutians late Tuesday evening and rapidly intensify
Tuesday night into a storm force low over the western Bering. The
strongest winds associated with this low will peak Wednesday over
the western Bering. The gale force front associated with the low
will spread rain and gusty winds from west to east across the
Bering, moving quickly to the eastern and northern Bering Sea by
Wednesday afternoon.

&&

.LONG TERM FORECAST (Days 3 through 7)...
The mid term forecast will see the western Bering low track to the
northeast bringing strong winds to the Bering and swinging its
front through mainland Alaska Wednesday night into Thursday.
There looks to be enough of a push of warm air from the south to
keep the precip as rain for the southern mainland. As this system
leaves Thursday night another low approaches the Bering from the
south. There still remains uncertainty amongst the models with the
track and strength of this system. Because of that, ensembles
were used heading into the weekend which offered a weaker solution
than the deterministic runs.
