Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK
106 PM AKST Tue Dec 6 2016

.DISCUSSION...
Models are similar through 60 hours. Upper level ridge building
into an Omega Block by Wed night over Eastern Bering Sea and
Western Interior. Upper level low in deep trough over Central Gulf
of Alaska originating from the Canadian Archipelago.

The high aloft will continue to create very strong surface based
inversions over Northern Alaska with 850H temperatures continuing
to warm significantly through the weekend. These temperatures will
spread East to cover nearly all of Northern Alaska the end of the
weekend.

By 96 hours the models begin to diverge substantially and in
particular upstream of Northern Alaska. This will greatly impact
any mid range confidence.

Bits and pieces of stratus are floating around the Arctic Coast
creating havoc in various locations in terms of TAFs and
temperatures.

The Tanana Valley Jet has eased slightly over Southeast Alaska
today but is expected to strengthen again by this evening and
stay in tact through much of the week.

Relatively light winds across Northern Alaska will remain over the
constant through the remainder of the week. Winds should remain
below marine advisory levels through Friday.

Coastal Hazard Potential Days 3 and 4...None.
