Southcentral and Southwest Alaska Forecast Discussion...CORRECTED
National Weather Service Anchorage AK
737 PM AKDT Mon May 1 2017

Updated to include long term discussion...

.PREV DISCUSSION... /issued 423 PM AKDT Mon May 1 2017/

ANALYSIS AND UPPER LEVELS...

An upper-level low sits over the Alaska Peninsula with the Pacific
Jet to its south. At the surface, a broad southerly flow is
keeping clouds over Southcentral and Kodiak Island. Radar trends
have kept light rain over much of Prince William Sound this
morning.

Clouds are spilling over the Western Alaska Range into
Southwest Alaska and the Bering. With a drier easterly flow,
visibility issues haven't cropped up for the mainland, but the
Pribilofs have had rounds of fog, rain and snow through the
morning as the islands sit on the edge of a stable and unstable
atmosphere. Radar trends have shown a scattering of rain showers
over the Bristol Bay region through the morning.

MODEL DISCUSSION...
Models were in good alignment and agreement at initialization.
Timing through the short-term was similar and a blend of the NAM-
GFS was used.

A modest amount of instability is noted this afternoon over the
Northern Susitna Valley and Kuskokwim Valley. The difference seen
today compared to previous days this last week is the absence of
mid- to- late morning sunshine today. This has kept convective
development in check through early afternoon.

The upper-level low will strengthen and shift from the Alaska
Peninsula to the Gulf of Alaska in the next 48 hours. As this
happens, a potent surface low in the Northern Pacific Ocean will
deepen and move north toward Kodiak Island through Tuesday
afternoon. While the greatest impacts will likely be felt in the
Panhandle, winds and seas will become a forecast challenge for
Southcentral.

For Southwest Alaska, a drier, colder flow featuring gap wind
challenges should be expected over the Alaska Peninsula.&&

AVIATION...
PANC...VFR conditions will continue tonight through Tuesday. Gusty
southeast winds will continue through late this evening.

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

The front along the north Gulf coast this afternoon is moving
northward into Southcentral Alaska overnight. There are some gale
force winds along this front which will diminish quickly after the
front passes. The airmass is unstable behind the front as
temperatures aloft are cold (running -30 to -35 C at 500 mb). This
is keeping widespread showers behind the front.

Tomorrow will be a transition day between systems in Southcentral
as a strong storm force low will move into the Gulf of Alaska
from the south Tuesday night. The front ahead of it will move into
the Gulf tomorrow and bring a bit of rain to the Gulf coast
beginning Tuesday afternoon. Areas to the lee of the Chugach and
Kenai Mountains will see most of the rain downslope out.

SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
The trough that is starting to push through the Bristol Bay area
will continue its northerly track and move through southwest
Alaska overnight tonight and Tuesday. As it passes it will kick up
showers with a slight chance of thunderstorms north and west of
Sleetmute. After the trough passes through, flow will become
northerly and diminish shower activity with the exception of some
afternoon showers and somewhat more steady rain around the Alaska
Range.

SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
As the low south of the Alaska Peninsula gets absorbed into the
stronger low approaching the Gulf from the North Pacific, a tight
pressure gradient will setup between this low and the ridging that
is moving across the Bering from the west. This setup will bring
strong northerly winds to areas around the eastern Bering, Eastern
Aleutians, and Alaska Peninsula through Wednesday. Behind the
ridge another system is approaching the Western Aleutians that
will make it to the islands Tuesday. This system will then push
into the northern Bering.
&&

.LONG TERM FORECAST (Days 3 through 7)...
On Thursday, the models are in fairly good agreement with holding
a weakening vertically stacked cyclone over the Gulf of Alaska
with several weak waves rotating around the center. This would
tend to keep most of the rain/showers across the Gulf though some
spotting showers will likely occur over the mainland with passing
upper waves. Ridging also looks to be over the eastern Bering Sea
with an upper low and associated surface cyclone heading toward
the western Aleutians.

By Friday afternoon, the Gulf cyclone has weakened and shifted
southeast. The upper ridge has now moved over Southwest Alaska
and the Aleutian cyclone is seen moving south of the eastern
Aleutians with its front spreading rain as fair east as the
Pribilof Islands and Alaska Peninsula.

By Saturday afternoon, the ridge has now moved over the eastern
mainland and extends south across the east Central Gulf. The
cyclone near the eastern Aleutians has stalled but its frontal
system stretches east spreading rain to Southwest Alaska and the
western Gulf.

On Sunday and early next week, model solutions start to diverge
and the weather picture becomes a little more fuzzy. The main
difference is the evolution of a Rex Block (high over low) with a
ridge setting up over the mainland and a trough over the Gulf.
The ECMWF/WPC solutions tend to move the ridge over the mainland
fairly quickly north while the GFS keeps the ridge over the
southern mainland through Monday night. The ECMWF/WPC solutions
(preferred) would cause the upper trough to shift further north
allowing moisture to intrude into the southern mainland. The GFS
solution would delay the moisture intrusion until Tuesday.
