Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
419 PM AKST Mon Mar 6 2017

.ANALYSIS AND UPPER LEVELS...
A very stable pattern is leading to persistent conditions across
the region, with a blocking ridge over the Bering Sea bringing
cold and dry conditions to mainland Alaska. Winds across
Southcentral are dying down today in the wake of the latest in a
series of cold air advection events. A short-wave ridge embedded
within the trough over mainland Alaska is bringing a halt to the
steady stream of upper level short-waves moving down from the
north (and associated reinforcement of cold air). To the west of
the upper ridge, the storm track remains over the far western
Bering with a series of weakening fronts bringing occasional rain
and wind to the Aleutians and central Bering Sea.

&&

.MODEL DISCUSSION...
As would be expected, model guidance remains in excellent
agreement with handling of this stable pattern and forecast
confidence is high.

&&

.AVIATION...
PANC...VFR conditions and light winds will persist.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
Clear, cold, and windy conditions will continue through Wednesday
and beyond as the highly amplified blocking pattern keeps dry
northerly flow entrenched over Southcentral AK. A weakening of
the pressure gradient will allow winds to subside somewhat through
Tuesday morning as a surface low over the eastern gulf moves away
from the area. Winds will then begin to ramp up again late Tuesday
into Wednesday morning as the Bering ridge nudges eastward and
shifts the upper level jet eastward over Southcentral. Even as
winds increase again through favored areas such as Thompson Pass,
they are expected to remain below warning level at this time.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
Generally sunny and cool weather will dominate the Southwest
Mainland into the middle of this week as an omega block continues
to hold over the Bering. This pattern will keep northerly flow
throughout the region, with becoming gusty at times over Bristol
Bay during the afternoon/evening hours. These winds will then
begin to diminish towards Thursday as high pressure over the
Bering moves into the region with otherwise continued quiet
weather.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
Very little change in the weather is expected over the Bering Sea
through the mid-week as a strong omega block keeps much of the
weather centered west of the Pribilof Islands. A front over the
Central Bering will slowly weaken as it moves northward in advance
of a another front spreading into the western Aleutians on
Tuesday. This will bring another round of gale force winds and
rain mostly to the west of Adak into Wednesday. Meanwhile the
blocking ridge will allow for diminishing winds and clearing skies
to the Eastern Bering/Aleutians into Wednesday.

&&

.LONG TERM FORECAST (Days 3 through 7)...
The high amplitude upper level ridge running across the eastern
half of the Bering and west coast of Alaska by midweek will tilt
east and widen Thursday and Friday expanding across Mainland
Alaska. As the ridge broadens, warmer air aloft will begin
pushing into Southwest Alaska Thursday and Southcentral Alaska
Friday and Saturday. Initially the higher elevations will warm
first, however with the increasing March sun angle, afternoon
high temperatures at lower elevations will begin a trend upward as
well. With the stable conditions underneath the large ridge,
patchy valley fog and low stratus along the coast will be a
concern although somewhat limited due to the prolonged dry spell.
With an anchoring upper low well south of the high, forming a rex
block, the large scale pattern looks quite stable with the high
remaining in place through at least early next week.
