Southcentral and Southwest Alaska Forecast Discussion...CORRECTED
National Weather Service Anchorage AK
605 PM AKST Sat Nov 25 2017

.ANALYSIS AND UPPER LEVELS...
The main weather feature over the region today is the strong and
still intensifying low centered in the western Aleutians and
encompassing most of the Bering Sea. This low has a strong
temperature gradient near the surface and is receiving strong
upper level support in the upper-left exit region of the jet
stream.
Downstream of this low there is an upper level ridge along the
Southwest coast of the state. A smaller, but not unimportant upper
level feature, is a shortwave trough that is over the Susitna
Valley which is helping to bring cold temperatures under and east
of it. This trough will also impact the movement of a weak upper
level disturbance moving westward along the north Gulf coast.

&&

.MODEL DISCUSSION...
The biggest model question for the past few days is the behavior
of the intense Bering Sea low after it moves into Bristol Bay
Sunday Night in to Monday. The ECMWF and Canadian models began to
shift the low farther south and across the Alaska Peninsula with
another strengthening low in the vicinity of Adak on Monday. The
12Z GFS run is now heading this direction as well as the 18Z NAM.
Therefore, confidence is increasing that there will be little, if
any, coastal flooding in the Kuskokwim Delta and Bristol Bay as
the track of the low and subsequent weakening of it are not
conducive for flooding.

The north Gulf coast also has a bit of a change that the models
are currently working out. The weak low tracking westward into
Prince William Sound from the east is moving faster and progressing
farther west that expected which is bringing some snow to the
sound today and could impact as far west as Anchorage tomorrow
before getting caught up in the upper level trough near the
Talkeetna Mountains tomorrow.

&&

.AVIATION...
PANC...VFR conditions and light northerly winds will persist into
Sunday. There may be some wind shear that develops late Sunday
afternoon with the northerly surface winds combined with
increasing Southeast winds at mountaintop level over the Chugach
Mountains.

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

The small area of low pressure over the northern Gulf has
certainly been outperforming today. Several hours of snow were
seen in Cordova, including some heavy at times, and that moisture
continues to press westward, now to eastern Prince William Sound.
As a result, the winds have been much slower to diminish through
Port Valdez, the Narrows and the Valdez Arm, and also in Whittier
as the low has kept the pressure gradient causing the winds
strong. The low is weakening, however, and the expected
continuation of that weakening should finally result in the winds
slackening off in all the above areas tonight. Meanwhile the
associated snowfall will continue moving west and envelop the rest
of the western Prince William Sound this evening. The associated
cloud cover will continue further, eventually causing the clouds
to increase across Anchorage and the Cook Inlet region late
tonight. That cloud cover should keep the temperatures up over
the western Kenai, Anchorage, and the Mat-Su Valleys, and the
coldest temperatures of the season are no longer expected tonight.

On Sunday, a strong warm front associated with a monster storm
over the Bering will make its way across Kodiak Island during the
morning. Precipitation will also continue across much of Prince
William Sound during the day (especially the west side), as a warm
southeast upslope wind kicks up. The precipitation will start out
as snow everywhere, then transition to rain in Kodiak Sunday
evening, and along much of the Gulf Coast and portions of Prince
William Sound by Sunday night. As the front pushes northward into
the coast late Sunday night, the winds will also kick up along
much of the Gulf Coast, causing a gale force barrier jet east of
Hinchinbrook Island through much of the day Monday before
weakening Monday evening. The gusty winds will also increase
through Passage Canal, Portage Valley, and Turnagain Arm Sunday
night into Monday as well. The ongoing snowfall should remain as
snow (albeit becoming a wet, heavy snow), but along with the gusty
winds could cause blowing snow and some visibility issues in
those same areas.

The strong southeast flow associated with the front Sunday night
and Monday is expected to downslope out anything more than
flurries or an isolated snow shower across Anchorage, the Mat-Su
Valleys, and western Kenai Peninsula. Thus Sunday night and
Monday will be much warmer, mainly cloudy, but also mostly dry in
those areas.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
Cloudcover will continue rolling into the area this evening as a
front associated with a rapidly deepening Bering low approaches.
This front will bring increasing winds along the Alaska Peninsula,
Western Capes, and Kuskokwim Delta coast by late tonight, which
will then quickly be followed by snow and blowing snow for much of
Bristol Bay and the Kuskokwim Delta coast. The heaviest
accumulations from this front will likely occur over inland and
western Bristol Bay where overrunning will allow for temperatures
to remain cold enough for more significant accumulations. Over the
Kuskokwim Delta coast, most of the snowfall should occur from
Nunivak Island southward, with areas further north and east only
receiving a glancing blow from the front and minimal
accumulations. The front should then dissipate from north to south
beginning Sunday evening, allowing for conditions to improve
throughout the area by late Sunday night.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
Winds will continue ramping up throughout the region this evening
as the intensifying hurricane force low crosses the chain near
Adak. Afternoon ASCAT satellite data confirmed a widespread swath
of 65-75 kt winds over the water to the south of this low, which
will continue spreading eastward tonight into Sunday morning. This
storm still has to potential to bring wind gusts near 100 mph
from Adak eastward all the way to Unalaska, with the strongest
winds developing from west-to-east late tonight into Sunday
morning. The models did trend slightly deeper with this low as it
stalls just south of the Pribilof Islands on Sunday, as a result
high winds are expected to last longer during the evening on
Sunday than initially expected. There is also very strong cold
air advection behind this low, which has already been strong
enough to bring accumulating snow to sea level in the Western
Aleutians, which will then spread into the Central Aleutians on
Sunday morning. Thankfully, this snowfall should be too wet/heavy
for significant blowing snow to develop despite the strong
northwest winds.

&&

.LONG TERM FORECAST (Days 3 through 7)...
Forecast confidence in the long-term period is fairly low at this
point, due to the run to run variation in the models over the
past few days. The overall change in the pattern from a clear and
dry pattern for the mainland to a warmer and stormier pattern
still stands, but the exact timing and effects of the low pressure
systems seems to change from model to model on a run to run
basis.

Current thinking is that a low will rapidly develop into another
storm-force system in the Bering Sea on Tuesday, bringing high
winds once again to the Aleutians. This low is expected to develop
a secondary low south of the AK Pen, pushing a strong front into
South Central Tuesday night into Wednesday. A lot of warm air is
associated with this front, which will cause some challenges with
forecasting precipitation type, in particular in the Bristol Bay
and Kenai Peninsula regions. High winds with the front may move
through Southcentral -- although current model runs are slightly
weaker than yesterday.

After Wednesday, another front moves into the Western Bering on
Thursday and begins to cross the Bering Sea. Although this
indicates a continued stormy pattern, the timing and strength of
this system is highly variable between model solutions, so
confidence in current specifics of the forecast remains low.
