Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
430 AM AKDT Mon Sep 11 2017

.ANALYSIS AND UPPER LEVELS...

Broad cyclonic flow continues across the Gulf of Alaska. Forcing
is weak with the longwave trough but with a residual pool of cold
air aloft there is sufficient instability to ignite isolated showers
over portions of Southcentral and the Gulf Of Alaska. Meanwhile
upstream, there is an upper level ridge which is keeping stable
conditions over much of the Alaska Peninsula and the Bering. The
latest ASCAT pass has pinged into a surface low northwest of Attu
with southerly flow coming across the western Aleutians. This is
an occluded system.

&&

.MODEL DISCUSSION...
Models remain in sync in the short term depicting the major
synoptic features. The run to run consistency lends itself to
above average confidence. The high resolution guidance was
favored for the local winds.

&&

.AVIATION...
PANC...Showers possible today. VFR conditions and light winds
will anticipated.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
Conditions will dry out over south central Alaska today as the
upper level trough that has been over the area moves east. A ridge
of high pressure will build over the area this afternoon into
tonight. On Tuesday conditions will begin to deteriorate again as
a strong system over the Bering sea approaches the area. This
system will be moving fairly slowly, as the amplitude increases.
This will also switch the flow aloft from westerly to southerly. The
pressure gradient will also increase across the Chugach
Mountains, bringing in gusty afternoon southeast winds to favored
locations like Turnagain Arm (including parts of Anchorage) and
the Copper Basin. Rain chances will slowly push east Tuesday
morning through Wednesday morning. Rain chances will be highest
over the Susitna Valley and Alaska Range, and the southern Kenai
peninsula.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
A pattern change will begin today as winds at all vertical levels
shifts to the southwest. Lots of mid-level clouds linger behind
the departing trough, but where there are breaks, temperatures
have radiated down near freezing. A disturbance will move just
north of the area through the day today, bringing a chance of
light rain to the Kuskokwim Delta and Valley. Later this evening,
a stronger frontal system will bring widespread rain to the area.
The front essentially stalls out and weakens over the mainland,
but several disturbances ride it inland, most notably on Tuesday,
which will bring more moisture to the Bristol Bay area. The moist
southerly flow stays active through late Wednesday, when cold air
wrapping back into the mainland will turn the rain more showery
than widespread.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
A warm front over the western/central Bering will usher in a deep
southwest flow over the area. Widespread rain will be confined to
the frontal boundary as it slides eastward through late tonight.
The front will stall over the eastern Bering as several
disturbances traverse it toward the mainland. Gale force winds
will wrap around the backside of the system then slowly weaken
through mid-week as the pattern turns more showery.

&&

.LONG TERM FORECAST (Days 3 through 7)...
The upper level pattern during the mid to late week will be
dominated by a longwave trough digging across the Bering and a
high amplitude ridge centered over the ALCAN border moving off to
the east. Southwest flow out ahead of an associated surface low
will spread precipitation across much of the region on Wednesday
and Thursday. The active pattern continues as a low pressure
system coming off of the northern tip of Japan will transit NE
towards the Western Aleutians and rapidly strengthen as it reaches
the Bering Sea. There is a fair amount of model spread this far
out with disagreements on the low track, though there seems to be
some consensus with the most recent Euro/Canadian runs showing the
low center moving into the southern Bering then SE across the
AKPEN into the southern Gulf of Alaska by the weekend.
