Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
426 PM AKST Tue Dec 13 2016

.ANALYSIS AND UPPER LEVELS...
Broad upper level ridging is in place over much of southern
mainland Alaska this morning. Troughing associated with the strong
vertically stacked low over the western Bering is slowly pushing
the ridge axis over western Alaska eastward. The jet is currently
split across southern Alaska...with an 80 kt jet northwesterly jet
streak moving over Southcentral, thus dividing the ridge into a
series of highly amplified skinny ridges and shortwave troughs.

While this upper-level pattern is quite complex, its tangible
effects on the surface weather have been minimal. The 12Z
Anchorage sounding is nearly the same as the past 3 soundings,
showing a strong inversion from near the surface up past 850 mb.
This reflects the ongoing pattern of warmer air aloft due to the
aforementioned upper level ridging over very cold air near the
surface, aided by the snow pack and relatively clear nights.
On the extreme side, Gulkana had its fifth night in a row with
lows in the negative 30s.

Southwest Alaska is in the transition zone temperature-wise.
Warming temperatures over much of Southwest Alaska have returned
many areas to the 20s and 30s after having also been in the deep
freeze for the past few days. A front nearing the coast is making
for windy conditions near the coast and the Alaska Peninsula,
though with gusts over 50 mph having been reported this morning in
Cold Bay. The front is associated with a strong low moving through
the western Bering. Warm and windy conditions were persisting
this morning over all of the Bering due to the winds wrapping into
the low. Nearly all stations in the Bering are seeing temperatures
in the 40s. The contrast between warm and cold air is helping
maintain the front as it moves towards the west coast of Alaska.

&&

.MODEL DISCUSSION...
Models overall are in good agreement through midweek across
Southcentral and the Gulf. In the west, models have a similar and
reasonable handling of the current Bering Sea storm. Significant
differences in solutions arise with the next storm approaching the
Aleutians Wed night. The ECMWF solution is much slower moving the
low north as it crosses into the Bering Sea Thu. On the other hand
the NAM is much weaker than all available solutions. The GFS/GEM
appear to have the best solutions.

&&

.AVIATION...
PANC...A mid level cloud deck over the Anchorage Bowl will break
up tonight, allowing some IFR and possibly low IFR conditions to
return to the airport later tonight. Conditions will then improve
around mid-day Wednesday.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
Ridging over the area is keeping most of the mid and upper levels
clear of cloud cover. However, stratus has formed under the
inversion as well as fog around the Cook Inlet area. This will
last through tonight before diminishing somewhat Wednesday. Then
Wednesday night patchy fog and more widespread cloud cover will
move back in over the area as a trough pushes in from the
southwest. This trough will bring back light snow to Southcentral
Alaska Thursday.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2...Tue and Wed)...
The "warm-up" is underway across much of the area with 850mb
temperatures rocketing upward under southwest flow. King Salmon
and a few other locales have already climbed up to or above
freezing. This warm air will continue to push north and slightly
east as the next front approaches early Wed. The underlying
problem with this scenario is that with this warmer air and some
precipitation associated with the front, there will be the chance
for some mixed and freezing precipitation across parts of the
area. Right now, it looks like the best bet for any freezing rain
will be in the colder, deeper valleys across the Kuskokwim Wed
mid-late morning. The warm air should mix in at the surface with
some gusty winds at places like Bethel and Dillingham, so the
threat of freezing precipitation is lower there. The pattern will
remain quite active with another, stronger front approaching the
coast by late Thu. Gusty southwest winds will keep temperatures
from cooling much in advance of this next front, so expect a
rain/snow mix along the coast with wet snow falling inland.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2...Tue and
Wed)...
Our storm force front over-performed in its trek across the
Bering. Winds and waves were a bit higher originally indicated
and it continues to be formidable as it moves through the Alaska
Peninsula. The parent low for this front is located way back at
175E. As some cold air wraps around the backside of it, yet
another pocket of storm-force winds and seas in excess of 25ft
will impact the Western Aleutians. There will not be much time to
reset from tonight's storm as the next one is right on its heels.
It will push into the Western Aleutians late Wed-early Thu. This
system will be a bit stronger than its predecessor as it holds in
a favorable spot along a 160kt jet. The primary concern will be
some potentially hurricane-force gusts wrapping around it on Thu.
Right now, it looks as if these will stay south of Atka and Adak,
but we will continue to monitor the system as it takes shape to
see if a high wind watch would be needed.

&&

.LONG TERM FORECAST (Days 3 through 7...Fri through Tue)...
A pattern change remains on track for late this week into next
week as a stacked low pressure system becomes stationary over the
western and central Bering Thursday night into Friday. This low
will help to usher a train of fast-moving systems in a strong jet
stream toward the general direction of the southern mainland and
Gulf of Alaska through the remainder of the long-term period. This
will bring a moderating trend to temperatures to all of our area
of responsibility, as well as increased precipitation chances,
especially along the coastlines. Trends suggest there may be ample
snow opportunities inland by early next week as well.

For the Bering, the main impacts will be strong winds given the
decent jet energy with the associated low pressure systems and
their associated fronts.
