Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
454 AM AKDT Thu Aug 31 2017

.ANALYSIS AND UPPER LEVELS...
The surface low remains centered just south of the tip of the
Kenai Peninsula near the Barren Islands early this morning with a
second wrap of the surface front continuing to bring precipitation
to Prince William Sound and the eastern Kenai Peninsula. A
deformation band stretches northwest away from the low and into
Southwest Alaska. Other features of note include a double upper
low/trough stretching from the west coast of Alaska down into
Bristol Bay, an upper level ridge over the western Aleutians and a
developing north Pacific low to its west.

&&

.MODEL DISCUSSION...
A blend of the NAM and GFS was preferred for both forecast
domains. For the west side, uncertainty remains high Friday and
Friday night regarding the details of the low in the Bering
transitioning energy across to the developing wave south of the
Aleutians. Once the low south of the Aleutians takes over and
strengthens Saturday, models become in better agreement with
forecast confidence improving for the weekend.

&&

.AVIATION...
PANC...VFR conditions will persist. While strengthening down
inlet flow has bent the surface southeasterly Turnagain arm winds
away from PANC with light northwesterly surface winds taking over,
wind shear may still be a concern on the approaches and
departures. Southeast surface winds are likely to push back in to
PANC late afternoon through the evening.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
The low that has been nearly stationary around Kodiak Island the
past day or so is now starting to lift northward into Cook Inlet.
As it does so the downslope that has been keeping Anchorage, Mat-
Su and other lee side areas mostly dry will diminish and allow
some rain today into tonight.

The center of the cold upper level low will move over the Susitna
Valley from the southwest on Friday which may cause enough
instability to cause a thunderstorm or two in the Susitna Valley.
There is a slight chance for a thunderstorm over northern
Talkeetna mountains and near the Alaska Range tomorrow afternoon
as well. The best chance is right underneath the cold pool of air
around the upper low center. There will not be a large break
between systems as the upper level longwave trough remains over
Southcentral into the weekend and then the next large system will
move into the Kodiak Island area by Saturday night.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
Active and rainy weather will continue for much of the area as a
series of upper level lows pass over the area. The first is the
same system that has brought rainfall to Bristol Bay since
Wednesday will continue to bring rain to most areas east of
Bethel today. This low will then depart the area this evening,
bringing a brief period of clearing for Friday morning. This will
be very short lived however as a second low over the Northern
Bering will quickly move into replace it for the remainder of
Friday into Saturday. This system will shift to focus of the
rainfall to the Kuskokwim Delta which has remained largely dry
this week. Depending on the exact track of this low there is an
outside chance that widespread rains will return to Bristol Bay on
Saturday from this system, however this was left out of the
forecast for now in favor of the further north solution over the
Kuskokwim Delta.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
We are beginning to see signs that the current pattern of broad
northerly flow over the region is beginning to break down as winds
have turned southerly over the Western Aleutians in advance of the
next system. Before this occurs, a weak trough will move through
the the Central Bering today, likely clipping the Pribilof Islands
with a brief round of rain showers while tracking into the Eastern
Aleutians. Further east, the very gusty gap winds that occurred
over the AK pen on Wednesday have began to diminish, though gale
force gusts should still be expected along the North Pacific coast
this morning. Beginning this evening the focus in the forecast
shifts to a low complex that will begin moving through the
Western-Central Aleutians on Friday. Overall forecast confidence
from this system is good, but not great, as there are small but
important differences from the models. The most significant of
these differences is how far north a rapidly developing low just
south of the chain will track late Friday-Saturday. The forecast
continues to favor the more northern solution from this system,
bringing gale force winds and widespread rains to the Eastern
Aleutians/AK pen. This is closest to the last 2 NAM and GFS runs.
If the NAM or GFS begin to trend towards the much further south
EC then significant changes may be necessary, in particular to
winds over the Eastern Aleutians/AK pen areas where the lowest
forecast confidence exists.

&&

.LONG TERM FORECAST (Days 3 through 7)...
The big question going into next week is what will happen with the
rapidly intensifying low south of the Aleutians. Depending on how
far south the trough digs it may tap into tropical moisture and
bring a long fetch of moisture to southern Alaska. Most current
operational runs and ensembles are indicating this to be the case
which would mean Monday and Tuesday would see steady, heavy rain,
primarily along the north Gulf coast. However, there are still
differences in where the low will setup and the trough may not dig
far enough south.
