Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
458 AM AKST Tue Dec 26 2017

.ANALYSIS AND UPPER LEVELS...
Overall, a pretty quiet pattern has settled in over the southern
half of Alaska as an upper level long wave trough/ridge couplet
occupies the western/eastern halves of the state, respectively.
Mostly clear skies have formed over southcentral tonight as high
pressure builds in from both the south and the north. Weak
northerly outflow winds are already appearing at locations across
the Gulf Coast, which should pick up during the day as high
pressure continues to build in. Over the Western Aleutians/Bering,
an upper level ridge is building in as a low pressure system tries
to make its way in to the area, with a pronounced cirrus shield
moving in aloft.

&&

.MODEL DISCUSSION...
Models are in good agreement regarding the overall synoptic
pattern. The hi-res models are of course handling the local
effect outflow winds along the Gulf Coast the best and will be
utilized heavily in the morning forecast package.

&&

.AVIATION...
PANC...Generally light winds and VFR conditions will prevail
today, though some patchy low stratus may develop this morning
over the Anchorage Bowl. There is an increasing chance of more
widespread fog/low stratus developing tonight/tomorrow morning as
an upper level ridge axis moves overhead.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
The weather pattern remains relatively tranquil over the next 48
hours, as high pressure currently centered over southeastern
portions of the Gulf relocates northwestward, taking up residence
near the mouth of the Copper River Delta by Wednesday. Increasing
heights/subsidence and warming temps aloft will strengthen the
inversion (wedge of warmer air). This will allow for some fog to
develop across portions of the Cook Inlet, including locations
near the Anchorage Bowl and lower Susitna River, and the interior
Copper River Basin through Thursday morning.

Otherwise, the main item of interest will be a developing offshore
flow. With light winds in place and cold air solidly entrenched
north of the coastal ranges, the pressure gradient will tighten
due to increased baroclinicity (temperature difference) between
the warmer Gulf waters and the snow-capped mountains. This will
in turn allow for cold air drainage to increase through the area
fjords and passes, with some gusty winds expected.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
As the pattern transitions from trough to ridge, lingering
moisture will promote widespread cloud cover early today which
should slowly erode by late this evening into the overnight hours.
Otherwise a transition to a colder air mass will begin tonight
with temperatures dropping into the single digits and teens across
most areas with each night/day this week getting progressively a
little colder. Variable winds tonight will turn from the north for
the remainder of the week.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
Several weak disturbances spin over the Bering, bringing at least
a chance for snow showers today. The pattern begins to shift as a
low pressure system and front take shape in the northwest Pacific.
Part of a north Pacific front will swing northwestward and bring
Unalaska a period of accumulating snow today before quickly
shifting west and dissipating. A stronger system will affect the
western and central Bering Sea with a gale-force front on Thursday
along with rain and snow.

&&

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

The upper level low in the Arctic is still slated to dig into
western Alaska by mid-week and become nearly stationary somewhere
in the Norton Sound area for the second half of the week. Upper
level high pressure will persist over the Yukon during this time
frame as well with the storm track remaining well south of the
state. What all this means for the weather is that temperatures
will drop down to near normal or a little cooler than normal over
most of southern mainland Alaska with periods of clear skies.

The Aleutians will see some snow or rain/snow showers as some
weak lows track through that region, but the main storm track
where the strong storms will go is south of there.

This pattern is likely to change during the weekend as the upper
level low weakens and we get into a more southerly push aloft.
This will brig in more mild temperatures as the storm track heads
closer to southern Alaska.
