Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
438 AM AKDT Mon Aug 14 2017

.ANALYSIS AND UPPER LEVELS...

The upper level wind pattern across the region still consists of a
mobile potential vorticity anomaly (which brought the extensive
rain Saturday) moving eastward toward the southern ALCAN border. A
westward retrograding piece of upper level energy has broken off
this low and is moving northwest of the Western Alaska Range.
There is an elongated upper trough slowly moving south through the
northern Bering Sea with a subtropical jet and a closed low
centered just south of Atka/Seguam Island in the Central Aleutian
Chain.

The surface pressure gradient consists of a surface low over the
North Gulf Coast with a broader area of low pressure over the
Central Interior of Alaska. This is promoting a broad cyclonic
flow over Southwest Alaska with a weak onshore pressure gradient
over Southcentral. Two large areas of precipitation are impacting
the Eastern Alaska Range and the northern parts of the Lower
Kuskokwim Valley/Western Alaska Range.

&&

.MODEL DISCUSSION...
The suite of numerical guidance (dynamical weather models) are in
pretty good agreement with one another with one lone
exception...and that remains the low crossing the southern Gulf
of Alaska tonight and early Tuesday. The biggest outlier was/is
the 00z NAM and now the 06z GFS. The main impact will be wind
differences over the marine offshore areas. Otherwise, model
continuity remains good through mid week until the details fall
apart once again with a developing trough Wednesday through
Thursday. The main differences revolve around how the northern
stream phases with the upper trough over the southeast Bering Sea
which will eventually impact precipitation distribution across
Southern Alaska. For now the forecast uses a blend of the 00z GFS
and ECMWF which generally keeps a continuity forecast and
continues with a theme of wetter weather Wed-Thu after a mostly
dry start to the week.

&&

.AVIATION...
PANC...VFR conditions will dominate today with moderate but gusty
Turnagain winds moving into the terminal late this afternoon and
continuing through the late evening hours.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
Broad cyclonic flow aloft with multiple embedded waves continue
across Southcentral through Tuesday. This pattern will bring
showery conditions and variable cloud cover. Showers in general
will be mainly confined to the mountains and areas along the Gulf
Coast. Abundant low level moisture from the recent rains and
partial clearing this morning may lead to stratus/fog development
early this morning from Cook Inlet across the North Gulf Coast.
Another arctic trough approaching the region late Tuesday night
looks to be bring widespread stratiform rains back to the region
for the second half of the work week.
&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
An upper level disturbance will continue to elongate and weaken
as it tracks northward across the southwest Mainland today,
keeping some scattered to isolated showers in forecast through
Tuesday. Otherwise, much of the region will remain dry under
mostly cloudy skies until the next system moves in Tuesday night
into Wednesday. This system will track southeasterly out of the
northern Bering and into the western coast of Alaska by Wednesday
morning, bringing increased chances of precipitation and gusty
winds along the Bristol Bay and Kuskokwim Delta coasts.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
A fairly steady state weather pattern is setting up across the
Bering for the next couple days. The one change is the low south
of the central Aleutians is expected to continue moving eastward,
such that it will be out of the area by Tuesday. Other than that,
general low pressure across mainland Alaska and building high
pressure over the western Aleutians will continue to support broad
north to northwesterly flow over nearly all of the Bering for
much of the week. Periodic disturbances moving southbound out of
the Arctic around a broad cold upper level trough will act to
intensify the winds with time going into midweek.

&&

.LONG TERM FORECAST (Days 3 through 7)...
The models seem to being doing better as they depict an upper
level closed low over the Chukchi Sea, and over the eastern
Bering by Tuesday time-frame. These features are on track to move
eastward as the closed low over the Chukchi Sea drops southward
into the northern Bering. While the other low over the eastern
Bering dissipates into a trough, and extends through the Southwest
Alaska region into the North Pacific Ocean by Wednesday. This
trough swings eastward before tracking through the Southeast
Panhandle by Friday. Meanwhile, the closed upper level low over
the northern Bering continues to track southward before moving
over the Alaska/Aleutian Ranges by Friday. This synoptic feature
tracks into the northern Gulf by Saturday morning, and moves along
the Southeast Panhandle going into Sunday. As these upper level
closed lows track through the Southwest/Southcentral area, they
will kick-off shortwaves through each region producing a showery
weather regime. Look for timing/intensity issues with these
troughs as they move through the different regions. Therefore,
the forecast confidence is average at best with continued cooler,
and wet conditions as we head into next weekend.
