Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
435 PM AKDT Thu Apr 6 2017

.ANALYSIS AND UPPER LEVELS...
A deep vertically stacked low south of Kodiak Island is drifting
west. A trough axis extends northwest from the low center across
the Alaska Peninsula and Bristol Bay to the Kuskokwim Delta coast.
This system is producing steady rain on most of Kodiak Island
with rain showers over Bristol Bay and the Kuskokwim Valley and
snow showers across the Kuskokwim Delta. Upper level deformation
just west of the surface trough axis continues to produce steady
snow along the Alaska Peninsula from Port Heiden south. The low
has begun to slowly weaken with northwesterlies through the Alaska
Peninsula showing a gradual downward trend. On the north side of
the low the strongest core of winds has shifted to Kodiak Island
and surrounding marine areas. Colder air (above the surface) which
wrapped around the low has crossed the Gulf and is moving onshore
of Southcentral, leading to showers (mainly in the Prince William
Sound region).

Meanwhile, a weak low and occluded front are elongating along the
Aleutians. The air mass is cold enough to support mostly snow,
though with surface temperatures above freezing it won't
accumulate.

&&

.MODEL DISCUSSION...
Aside from minor position differences with the weakening low
south of the Alaska Peninsula the next couple days models are in
excellent agreement. Thus, forecast confidence is high.

&&

.AVIATION...
PANC...With interior portions of Southcentral beginning to heat
up each afternoon, it does look favorable for a period of
southeast winds (bending out of Turnagain Arm) this afternoon
into evening. The gusty winds should be fairly brief and not all
that strong. Otherwise, expect VFR conditions to persist.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
The very slowly weakening low over the extreme Southwest Gulf will
continue to bring rain and gusty east winds to Kodiak Island and
the Western Gulf into Friday. Expect the heaviest and most
widespread rainfall to occur late tonight through Friday morning
as the last of the front pushes through. This will bring gale
force winds and at least 1 inch of rain to most areas, especially
along eastern facing slopes.

Further to the north the weather will remain much quieter with
diminishing winds and showers passing over the area with continued
broad cyclonic flow. Most of the showers should remain over the
east side of the Chugach, however with weakening downsloping and
an increasing unstable environment it wouldn't be out of the
question to see a few of these showers briefly fall over
Southcentral. Anything that does develop should be fairly brief
and light. An exception to this will be over the Susitna Valley
where additional instability from sunny skies and temperatures in
the 50's will bring scattered rain showers. Improving weather will
then spread throughout the region as the gulf low exists to the
southwest and weak ridging aloft develops.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 through 3)...
The Southwest Alaska region continues to see moisture spilling
over from the low pressure just south of Kodiak Island. This is
resulting in warm air advection across the Alaska Range and Aleutian
Mountains extending south into the Alaska Peninsula. The Bristol
Bay and the Lower Kuskokwim Valley has temperatures in the upper
30s to lower 40s. Therefore, expect a continued showery regime
with the precipitation as all rain for the aforementioned region.
Meanwhile, look for a wintry mix over the Ahklun and Kuskokwim
Mountains except for all snow west through the Kuskokwim Delta.
The showery regime will taper off by Friday with only the Alaska
Peninsula remaining under the influence of the low pressure system
south of Kodiak. The gusty gap winds along the Alaska Peninsula
combined with the cooler temperatures overnight will give way to
the precipitation changing over to snow resulting in areas of
blowing snow through Friday morning.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 through 3)...
The jet stream remains northwesterly over the western Aleutians
as it digs into the longwave trough over the North Pacific Ocean.
This synoptic feature steers the gale force low over the western
Aleutians through the lower western Bering into the North Pacific
Ocean just south of the central Aleutians by Friday morning. This
brings a wintry mix of precipitation along the Aleutian Islands
before cooler air filters in on the backside into the western
Bering/Aleutians as the low exits our AOR. Meanwhile, the eastern
Aleutians continue with gusty northwest gap winds with areas of
blowing snow through Friday before the pressure gradient weakens
resulting in weaker gap winds. Farther upstream a storm force low
drops down off the Kamchatka Peninsula and approaches the western
Aleutians by Friday afternoon. The associated front tracks
through Shemya during the same time frame accompanied by gale
force south winds. By Saturday midday this low pressure system
will be located over Shemya with the associated weather front
extending through the central Aleutians, and the western Bering.

&&

.LONG TERM FORECAST (Days 3 through 7)...

Beginning the extended forecast period Saturday night, the main
Pacific storm track will remain well south of the area of
operations as high latitude blocking remains strong over the
Beaufort Sea. Weak troughing will remain over Alaska, however,
without a deep moisture tap or well defined Pacific moisture
connection, precipitation activity inland looks sparse. With the
continued weak onshore flow pattern, expect temperatures to
continue to run at or slightly above average with many areas
seeing freeze/thaw diurnal patterns.

Late Monday the large scale synoptic pattern will shift with the
Pacific storm track shifting into the Bering. The first strong
gale force low looks to move through most of the Bering Sea by
Tuesday. A brief period of dry inland weather will become
dominated by the eastward progression of the Bering front, first
into Southwest Alaska as early as Tuesday night. At this juncture,
overall confidence drops quickly as there remains much
uncertainty with the strength of the North Pacific ridging
extending into northwest Canada. Climatology would favor
increased heights inland and a slower eastward progression of the
front, an idea supported by the GFS, Canadian, and the respective
ensembles. The ECMWF deterministic remains an outlier as this
solution moves the front east and stalls it over the Alaska Range,
the net effect being robust moisture/precipitation will be
possible across much of Southcentral through most of the week
after Tuesday. For now, this forecast favors the former approach
(i.e., stronger inland ridging) which will keep the bulk of
moisture across the Bering and coastal southwest Alaska into
Kodiak Island. Should the ECMWF look to verify in the coming days,
then the latter scenario will need to be reflected in upcoming
forecasts. However, for now, the WPC ensemble approach is favored.
