Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK
106 AM AKDT Tue Sep 18 2018

.DISCUSSION...
A generally unsettled weather pattern is expected for the west
coast and the western Interior this week while the weather will
be relatively quiet through the workweek elsewhere. The models
are in generally good agreement with the overall synoptic scale
pattern out through the end of the week; however, they differ in
the exact track, timing and strength of synoptic scale features
next weekend and beyond with large differences in the time, track
and strength of a strong low pressure system expected to move
into the Central Bering Sea next weekend.

Aloft at 500 mb, a weak upper level low moving west over the
northern interior continues to be absorbed by an upper level low
moving southeast off of the Chukotsk Peninsula over the Bering
Strait and Kotzebue Sound Wednesday the western Brooks Range
Wednesday evening and over the central Brooks Range an central
interior Thursday. An upper level ridge builds north and east into
the eastern Bering Sea Wednesday and Thursday.

On the surface a 1033 mb high pressure system 350 nm north of
Demarcation Point will continue to move south and east over the
northern Yukon through Thursday. A surface reflection of the upper
level low moving east southeast out of the Chuktosk Peninsula will
develop over Kotzebue Sound Wednesday morning and will continue to
deepen to 1012 mb as the low moves east along the southern Brooks
Range Wednesday and Thursday. Widespread rain will move into the
Seward Peninsula and West Coast Wednesday and into the Western
Interior and Western Brooks Range Wednesday evening and Thursday.
Rain moves into the Central Brooks Range as well as the Central
Interior and Central Alaska Range Thursday as surface high
pressure moves south and east out of the Beaufort Sea into the
Northwest Territories late Wednesday and Thursday.

Computer models continue to indicate a stormy weekend over the
Central and Eastern Bering Sea as well as the West Coast of
Alaska with the exact details on the track, and strength of a
strong low pressure system forecast to move into the central or
eastern Bering Sea not being handled well yet at this point.
Continue to monitor

Snow levels in the 4 kft to 5 kft range both in the Brooks Range
and Alaska Range will lower through the week with minor snow
accumulations indicated over Atigun Pass by the end of the week
and snow level expected to remain above pass level in the Alaska
Range.

Coastal Hazard Potential Days 3 and 4...As a low pressure system
moves through the Bering Strait and over the Seward Peninsula
Wednesday and Thursday expect 25 to 35 mph on shore winds to
produce elevated water levels along the Yukon Delta Coast late
Wednesday and Thursday. The duration and strength of the winds
combined with relatively short fetch will limit water levels with
only minor beach erosion expected.
