Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
410 PM AKDT Fri Apr 14 2017

.ANALYSIS AND UPPER LEVELS...
Strong ridging dominates Mainland Alaska with bluebird skies
across most of Southcentral and Southwest Alaska. The one
exception is the southwest coast where areas of fog (locally
dense) formed in an ideal location under the ridge with steep
surface-based inversions. Meanwhile, a deep low is passing just
west of the western-most Aleutian Islands while an associated
occluded front elongates and weakens as it slowly progresses
eastward into the eastern Bering Sea.

&&

.MODEL DISCUSSION...
Model guidance is in good agreement with large scale features and
forecast confidence remains high.

&&

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

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
The relatively warm and sunny days with cool and clear nights are
expected to continue across much of Southcentral Alaska this
weekend. Kodiak Island will be the exception though as
increasingly easterly flow and upper level disturbances will bring
increased chances of showers overnight tonight through much of the
weekend. Elsewhere, brisk outflow conditions across the mainland
will continue to diminish through early this evening as pressure
gradients continue to relax over the area. As the offshore
gradient relaxes later this afternoon, early evening sea-breezes
will develop and help to keep afternoon high temperatures along
the coasts slightly low than previous days.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
Weak flow across the region increases out the east to southeast
direction tonight as low pressure stalls across the Bering and
high pressure builds into the gulf. This should improve fog
conditions across the region by late Saturday morning. However if
the low level flow does not increase as currently expected, areas
of fog will be possible as a cooler, and more stable, air mass
advects across the Alaska Peninsula to Bristol Bay Saturday night.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
The front across the Central Bering to eastern Aleutians stalls
tonight bringing a mix of rain and snow then diminishes slowly
through the weekend. Gusty winds along the boundary tonight stay
in the small craft advisory range for marine areas. On Saturday,
winds taper down as ridging builds across the Central Aleutians to
the northern Bering. A second front moving into the western
chain tonight advects a colder air mass across the western half of
the Bering into Sunday.

&&

.LONG TERM FORECAST (Days 3 through 7)...
The current weather pattern looks like it will remain in place
through about Friday. Through Thursday, the upper level jet will
remain far to the south, with relatively calm weather affecting
most of the forecast area. An upper level high poised over the
Arctic will move slightly westward during this time, bringing
northerly flow and cooler but not unseasonable temperatures down
over the mainland. Weak troughing over the eastern Bering may
bring some showers to the area midweek but these will have minimum
impacts.

As we move into Thursday/Friday, the upper level pattern begins to
show an indication of a shift to a more north-south flow. This
will bring colder showers to the western Aleutians and the
opportunity for low pressure systems to move into the Gulf of
Alaska. Current thinking is that the first effects from this
pattern shift will occur Thursday morning with a weak trough
moving in from the East along the Gulf Coast. This will be
followed by a stronger low pressure system moving into the Gulf on
Friday. Models are consistent in showing this pattern shift,
however, timing is uncertain. Therefore, confidence is moderate
that we'll be moving to rainier pattern along the Gulf Coast by
next weekend, with low confidence on the timing of actual bands of
precipitation.
