Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK
509 AM AKDT Thu Nov 3 2016

.DISCUSSION...
Models in fairly good agreement through the weekend. Weak upper
level ridge over Northern Alaska extending from Western Canada
westward through the northern tier of Alaska.

Meanwhile moderately strong upper level low in the Bering Sea
will continue to rapidly weaken. This will allow for a long wave
trough develops southward over Northern Alaska. Upper level trough
should remain in place through Tuesday.

Boundary and surface level winds should begin to subside over the
Arctic Coast through Friday. The strong winds are originating from
a strong upper level high that is currently over the high arctic.
This has prompted Gale warnings in many locations in the gradient
flow over the Arctic Coast. The flow over the Arctic Coast will
primarily be either parallel or onshore. This has the potential
to bring in stratus and fog on the Arctic Coast.

As the upper level trough builds in over the Interior. clouds will
become more prevalent and surface temperatures will remain much
warmer than normal although the 850H temperatures will continue to
fall with the upper level trough building in.

Flurries will likely be the rule of thumb across the Arctic Coast
given the onshore flow.

A short wave moves up over the Eastern Interior by Saturday and
may spread some very light snow or flurries into the Interior.

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