Southcentral and Southwest Alaska Forecast Discussion...CORRECTED
National Weather Service Anchorage AK
553 PM AKDT Thu May 4 2017

.ANALYSIS AND UPPER LEVELS...
The upper level low over the mainland part of the state and into
the Gulf of Alaska has weakened into a trough while the low south
of the Aleutians has strengthened since yesterday.
Correspondingly, the surface low in the Gulf is significantly
weakening and beginning its drift southeastward where it will
dissipate Friday.
The surface low south of the Aleutians is near its maximum
intensity right now in the mid to upper 970s mb. This low is
becoming vertically sacked and will slowly move eastward and
weaken.
Areas of greatest instability over the mainland part of southern
Alaska this afternoon and evening are in the Susitna valley and
Western Kenai Peninsula with the Susitna Valley having the
greatest instability. In spite of this, it is still unlikely for
any thunderstorm development over the region today with just some
locally heavy showers. Some of the heavier showers could contain
some small hail as freezing levels are generally 4000 ft or less
this afternoon.

&&

.MODEL DISCUSSION...
Models continue to be in good agreement with the two main weather
systems. What becomes worth noting is on Saturday when a triple
point low develops just southwest of the Gulf of Alaska. While all
the models have this low there is a bit of a difference as to how
fast this low moves through Sunday with the GFS being considerably
faster than any other solution. This will have an impact on the
timing of rain and winds in Bristol Bay, Kodiak, and the Alaska
Peninsula in particular.

&&

.AVIATION...
PANC...VFR conditions will persist through Friday. The Turnagain
Arm wind will keep gusty southeast winds at the airport well into
the evening and then should diminish as temperatures cool in the
Susitna Valley. Tomorrow's winds look to be more of a sea breeze
influence with light westerly winds.

&&
.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
Sunny and warm conditions will continue for much of Southcentral
through Friday as weak high pressure moves through the area. Ahead
of this approaching high pressure, a weakening pressure gradient
along the Gulf Coast will produce gap winds from Turnagain Arm
eastward into the Copper River this evening, along with gusty
southeast winds over the west Anchorage. These winds are expected
to be much weaker on Friday as high pressure moves through,
allowing for temperatures to rise into the low 60's for much of
the Anchorage Bowl and MatSu Valley's. Pleasant weather will then
continue into Saturday for much of interior Southcentral. Further
south, rain and gusty east winds will develop over Kodiak Island
late Friday-Saturday as a frontal system moves through. This system
will then spread into the north Gulf Coast for the remainder of
the weekend.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...

Showers develop this evening along a trough situated across the
eastern Kuskokwim Valley and eastern areas of Bristol Bay.
Southerly flow returns across the region on Friday as the Bering
front pushes east toward the coast. The frontal boundary is
expected to push across the Alaska Peninsula by early Friday
afternoon. The coastal areas of Bristol Bay and the Kuskokwim
should see rain developing during the late afternoon and early
evening. The front rapidly diminishes friday night into Saturday
as the surface low fills while crossing into the southern Bering.
A few showers will develop inland on Saturday along the weakening
boundary, with the highest chances along the mountain ranges.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...

A front along the southern Bering remains nearly stationary
through tonight with a re-enforcing surface low keeping gale
force winds along the boundary through much of Friday before
tapering down. A prolonged period of northerly gales can be
expected on the backside of this low pressure system as ridging
approaches the western Aleutians on Saturday, forcing a tighter
gradient along the central Aleutians and Bering.

&&

.LONG TERM FORECAST (Days 3 through 7)...
Next week will be characterized by high pressure that will build
in over the Bering and try to stretch into mainland Alaska. This
ridging will help to push off the low that will be in the Gulf of
Alaska but it will not be quite strong enough to inhibit afternoon
convection for much of the southern mainland. Mid week another low
will move in over the Aleutians from the south while the ridging
moves more prominently over the mainland.
