Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
509 PM AKDT Fri Sep 1 2017

.ANALYSIS AND UPPER LEVELS...
A long-wave trough is centered over the Alaska region with two
strong jet streaks on either side of the trough; one driving
eastward along the Aleutians then southward into the north central
Pacific and the other extending northeastward out of the base of
the trough up to Southeast Alaska. There are multiple closed lows
embedded within the trough. One is lifting northward up Cook Inlet
and the Susitna Valley producing scattered to numerous showers
across Southcentral. A larger deeper low is nearly stationary off
the west coast of Alaska, with a short-wave trough on the south
side rotating eastward into the Kuskokwim Delta, with a few
showers headed inland.

All eyes are on the third upper level low over the southwest
Bering Sea. A strong short-wave on the back side of this low is
digging southeastward toward the north Pacific. This will amplify
the flow and lead to rapid development of what is now a weak
surface low tracking eastward along the subtropical jet. This
interaction is expected to begin tonight and continue through
Saturday. The end result will be a highly amplified pattern with
a storm force surface low south of the Alaska. Ultimately this
will lead to development of an atmospheric river in the Northeast
Pacific/Gulf of Alaska, which is the main forecast challenge for
early next week.

&&

.MODEL DISCUSSION...
Models continue to shift with details of the development/track
of the deep low and placement of the atmospheric river. In
particular, after a trend toward more progressive upper level
pattern on Thursday, the models have all shifted back toward a
solution more similar to Tuesday's runs. This would lead to an
atmospheric river pointed toward Cordova or areas just to the
east Monday through Tuesday. There is still some spread among
the various models, but all indications are increased confidence
in a heavy rain event for eastern Prince William Sound.

Aside from the uncertainty in the exact placement of the
atmospheric river (and heaviest rainfall), guidance is much more
consistent with the overall strength and location of the storm
system south of the Alaska Peninsula. Thus, forecast confidence
is generally very high with the expected weather from this system.

&&

.AVIATION...
PANC...VFR conditions will persist. Showers will remain in the
vicinity through this evening, so ceilings could briefly drop
below 5000 ft. With unstable low levels and favorable up Inlet
flow, expect gusty southerly winds to persist through the
overnight hours. Winds should then cut off sometime Saturday
morning as flow shifts to down Cook Inlet out ahead of the deep
low forming south of the Alaska Peninsula.

&&

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

The main focus for the upcoming Labor Day weekend is focused
around a storm system moving just south of the alaska Peninsula
late Saturday. Ahead of this system, a broad area of low pressure
centered over the southwest mainland will initiate a few showers
through Saturday. A cooler air mass will keep temperatures at or
below normal through Sunday with gusty diurnal winds expected. The
storm system of concern moves a front across the southern gulf and
Kodiak Island Saturday evening with rain and winds expected to
rapidly increase along the boundary. This system swings the front
to the northern coast by late Sunday. The heaviest precipitation
will be along the gulf and Prince William Sound coasts as strong
southeasterly flow downslopes rain across the mountain ranges.
Gustier winds are anticipated across channeled terrain as the
pressure gradient is squeezed with the frontal push Sunday through
Sunday night.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
Southwest continues to be dominated by an upper level trough
centered over the northern part of the state. A shortwave swinging
along the base of trough will bring an area of rain and showers
through the Y-K Delta region and then east across the lower
Kuskokwim River Valley tonight. With increased cloud cover over
the region, tomorrow morning's temperatures will be warmer than
the previous morning, where temps dropped to near or below the
freezing mark in several locations.  There will be a brief break
in the weather on during the day on Saturday before the next
systems approaches the area overnight.

A very strong low pressure system moving in south of the
Aleutians will begin to pump in moisture to the area with SE flow
picking up and rain spreading into the Kuskokwim River Valley and
the Bristol Bay area by Saturday night. Strong SE winds will also
begin to pick up Saturday night and will increase through the day
on Sunday as a low level jet moves in ahead of the low. By Sunday
afternoon, winds are expected to be in the 30-40 mph range on the
west side of the AKPEN and the Bristol Bay coast, with gusts
reaching up to 50-60 mph as winds become accelerated through
terrain gaps. Downsloping is expected to develop on the lee side
of the Aleutian Range by Sunday afternoon and should help to taper
off precipitation in those areas.

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
 A low just south of the Aleutians will rapidly deepen on Saturday
into a storm force, sub 970 mb low by the end of the day on
Saturday. The low will move east to about 250 mi south of Dutch
Harbor and bring widespread gale force winds to areas east of
Dutch Harbor by Saturday night. Heavy rain will also impact the
region and strong southerly flow will tap into subtropical
moisture. The low is expected to stall out on Sunday as high
pressure to the east blocks any further progression. This will
mean continued gales with areas of storm force winds along the
southern AKPEN south of Kodiak throughout the day on Sunday.

.LONG TERM FORECAST (Days 3 through 7)...
The remnants of the storm force low from this upcoming weekend
will remain parked just south over the Eastern Aleutians on Monday
through Tuesday afternoon. The models have struggled with this
system with the NAM being the outlier in pushing this system
farther north into the Eastern Aleutians. The GFS was the
preferred model of choice with keeping the aforementioned synoptic
system farther south of the Chain. The key feature is the
atmospheric river that will develop resulting from this system as
it coincides with the strong 130 knot southerly jet streak
located over the Gulf of Alaska as it streams northward through
the Southcentral Region. This provides abundant moisture which
will stream northward resulting in potential heavy rainfall issues
to occur along the northern coastal communities from Cordova
eastward to Yakutat during the early part of next week. Therefore,
a Flood Watch has been issued for the Southeast Prince William
Sound, and Cordova from Monday morning through late Tuesday night.
While the Anchorage Bowl looks to remain downsloped resulting in
drier conditions through Thursday, but there maybe a few isolated
showers making it over the mountains with continued cooler
temperatures with cloudy skies through the midweek. Meanwhile,
the remnants of Typhoon Sanvu approaches the Western Aleutians by
Monday morning. The models are struggling with the
timing/placement of this synoptic system. By Wednesday afternoon
this low pressure system looks to be located over the Central
Aleutians near Atka before crossing over into the North Pacific
Ocean by early Thursday morning. This will bring widespread gusty
winds accompanied by stratus/rain with the Bering/Aleutians to be
under the influence of strong gusty northeasterly to northerly
winds as it tracks eastward through the midweek.
