Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK
611 AM AKST Wed Dec 13 2017

The active southerly flow pattern continues across northern
Alaska and is anticipated to continue through the short term. All
areas in our forecast area can expect to see impacts of some kind
as a result. Details are below. Models are in agreement in the
short term as well, though they differ on some of the fine scale
details. Forecast confidence remains strong.

Central and Eastern Interior: Winds in the Alaska Range continue
to be the main issue. Chinook conditions have been occurring
overnight tonight and are expected to continue through the day,
subsiding early tomorrow. High wind warnings are out for areas
along the Alaska Range and a wind advisory is out for the Delta
Junction area. Due to the Chinook, warm temperatures will
continue in the Interior at least until Thursday, then a slight
cool off is expected. While temperatures are warm enough for
freezing rain, no significant precipitation is expected due to
drying flow over the mountains.

North Slope and Brooks Range: Winter weather advisories continue
for much of the Arctic Coast due to a tight pressure gradient
inducing high winds and blowing snow at the surface. These
conditions are similar to a ground blizzard in nature, but are not
strong enough to meet blizzard conditions in most locations. The
one exception is around Point Lay on the northwest Arctic Coast
where the winter weather advisory has been upgraded to a warning
for blizzard conditions. Expect this inclement weather to continue
until Thursday.

West Coast and Western Interior: The low pressure system moving
north through the Western Interior is bringing unusually warm
temperatures to both the Western Interior and the West Coast.
This is causing mixed precipitation to fall, including freezing
rain for areas as far north as the Koztebue Sound and Western
Brooks Range. Most areas will see less than one tenth of an inch
of freezing rain with advisories being issued for 208, 209, 211,
212, 217 and 227. Zones 215 and 216 will see heavier amounts of
freezing rain with a storm total of up to one quarter of an inch
falling so they remain warnings. Northern areas like zones 208,
209 and 217 can expect to see mixed precipitation transition to
all snow tonight after the low passes and temperatures cool. Those
locations can anticipate receiving about 4 inches of snow as
in addition to freezing rain.

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