Northern Alaska Forecast Discussion

534 AM AKDT Mon Mar 27 2017
Models in decent agreement through 60 hours. Upper level trough
remains over Mainland Alaska. Upper level low working its way
eastward and then northward ends up moving due north by early
Tuesday morning to near 80 N. This will be the last immediate
feature to attempt to bring in a reinforcing shot of cold air
from the Russian Arctic.
Currently, the surface high pressure over the Arctic Plain is slow
to move north while the low in the North Pacific continues to push
north at a faster pace. This is tightening up the pressure
gradient over the Central Interior of Alaska. This gradient is
producing north winds to increase through the day and in some
areas to maintain strength till early Tuesday. The winds are
setting up to be fairly strong over higher terrain.
It is likely with the stronger winds that some of these areas will
be impacted with blowing snow and in particular, the Dalton
Highway and its summits.
Little snowfall is expected from Monday through late Tuesday
night. The short wave aloft spins up from the southeast but
southerly flow will dry out much of the precipitation before it
reaches the interior. Successive short waves will continue to
experience the same problem with southerly flow over the next
couple of days. So snowfall will be light over the Central
Interior although there will be some areas light snow. It may add
to the visibility reduction over the summits with the enhanced
wind through Tuesday though.
