Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
505 PM AKST Mon Jan 8 2018

.ANALYSIS AND UPPER LEVELS...
Challenges for this forecast period will continue to focus around
be low stratus and fog near coastal areas of Southcentral and
developing outflow winds.

There's sun to be had if you can climb a small hill. Water vapor
imagery shows the heart of mid- and upper- level dry air over the
Copper River Basin, Matanuska and Susitna Valleys, Anchorage Bowl
and Kenai Peninsula. But a shallow layer of moist and frigid air
is locking in freezing fog for many in these areas, with the
exception of the Susitna Valley.

In Western Alaska and along the Aleutian Chain, challenges will
focused along the movement of a Aleutian Low and associated front
and lingering fog and stratus and usual garden-variety rain and
snow.

A broad upper-level low sits over the Southern Bering Sea while a
high sits over Western and Interior Alaska. A vort max is moving
out of the Southern Yukon into the Gulf of Alaska this afternoon
as an Arctic trough drives southeast into Interior Canada.

&&

.MODEL DISCUSSION...

Models initialized well this morning capturing the vertically-
stacked 949mb surface low near Adak. Models were not capturing the
low-level moisture and stable layer sufficiently. Webcams and obs
remained the best tools available for short term updates.

In both the East and West regions, the preferred model was the
GFS. However, the NAM-nest was used to help with local outflow
wind effects in the East. An interesting change from previous
thinking seemed to be shaping up with big cold over the Interior
and Yukon not pushing as far West. Beyond temperatures outlooks,
this will have impacts on outflow winds developing in the coming
period.

Beyond the next few days, the Pacific jet makes a push in from
south over Southcentral Alaska while becoming more zonal in the
West.

&&

.AVIATION...
PANC... IFR/LIFR conditions in stratus and fog should end this
evening as northerly winds increase across the airport complex.

&&

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

High pressure will build over the Arctic while several weak
systems try to push into the southwest portion of the Gulf. This
will make for cold and breezy weather across the southern mainland
for the next few days. Very cold air (850 mb temperatures
approaching -40C) over the Yukon have limited high temperatures
there in the -35F range. Northeast flow will bring this airmass
into southern AK starting late tonight into Tue. However, it will
only be a glancing blow (mostly the Copper River Basin) and it
will be short- lived. Other than cold temperatures, the other
impact from this airmass will be gusty offshore winds. These will
be most pronounced through the Copper River Delta and coming down
through Thompson Pass into Valdez. Winds look to peak during mid-
late morning Tue as upper level support pushes through the area. Some
of the other typical spots like Whittier and Seward will actually
not see the strongest winds with this event due to the
orientation of the cold air.

Meanwhile over the SW Gulf, it will be a much different story.
Several weak occluding warm fronts will push towards precipitation
into Kodiak Island. It looks like enough cold air will hang on
with the first system Tue to keep snow for Kodiak City. But when
the next front arrives on Wed, we will see a transition from snow
to rain through the day at sea-level on the island. None of these
features looks to bring a significant amount of precipitation.
These fronts will provide enough south-southeasterly flow across
most of South Central to spare much of the region from the truly
cold air. They will eventually push snow back into the North Gulf
Coast and Western Prince William Sound by Wed afternoon. Modest
southeast winds at mountain top will keep the usual lee-side
locations (Kenai, Anchorage, Palmer) mostly dry. This pattern
looks to establish itself through the end of the week with warmer
and moister southeast flow becoming the rule.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
The pressure gradient along the southwest coast continues to
tighten up, with slowly weakening high pressure over the mainland
and an approaching front pushing in from the southeast Bering this
evening. This will keep the drier and colder offshore pattern
around through much of the short term, and will hinder fog
development for much of the southwest Mainland. A few localized
areas along the Aleutian/Alaskan ranges and the Lower Kuskokwim
Valley will likely see patchy fog persist overnight tonight into
Tuesday morning, as winds are expected to remain on the light side
through tomorrow morning. Precipitation is expected to remain
mostly along the coast with the initial frontal system glancing
the coast, as well as with the second wave tracking across the
AKPen Tuesday evening through Wednesday.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
A strong low pressure system over Adak will continue to slowly
weaken and track southeastward back into the north Pacific, while
the associated front weakens and tracks through the eastern
Bering and AKPen through tonight. The strong northwesterly gusts
over the western Aleutians/Bering, and the gale force gusts over
much of the remaining Bering Sea will begin to taper off Tuesday
morning as the low starts tracking southeastward and continues to
weaken. Light to moderate rainfall along with some visibility
reductions are expected to remain in place across parts of the
Aleutian chain and Bering sea, as the above mentioned low/front
lingers over the region through Tuesday night. Overnight Tuesday
into Wednesday night, a second system is expected to quickly
approach the aforementioned system from the west and act to
reinvigorate gusty and showery conditions over the eastern
Aleutians and AKPen through Thursday afternoon. Models continue to
struggle with the finer details regarding this system, so forecast
confidence is slightly lower with regards to the strength and
timing of winds an precipitation.

&&

.LONG TERM FORECAST (Days 3 through 7)...

As we get into the long term period on Thursday, the upper level
pattern over the state will be in the midst of a change. Thursday
will start off with the upper level high just offshore the Arctic
coast with the main upper level low just south of Dutch Harbor.
This will start the mild south-to-southeast flow once again over
mainland Alaska with east-to-northeast flow over the Bering Sea.
The jet stream will remain running west-to-east well south of the
Aleutian Islands and Gulf of Alaska. As the weekend arrives the
low in the Aleutians will remain in the general area, but the
upper level ridge will shift over Canada and a jet streak will
move south of the low, through the Gulf of Alaska and then around
the northern periphery of the ridge in the Yukon. The result will
be for a noticeable warm up in temperatures with the potential
for Chinook winds in Southcentral and/or Southwest Alaska over the
weekend.
