Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK
518 AM AKST Mon Jan 16 2017

.DISCUSSION...
Models in decent agreement through 60 hours. Upper level low
pushing south with reinforcing cold air. Current location of low
is just off the coast of Point Hope. The GFS keeps a low center on
the Chukotsk Peninsula Monday night while the ECMWF keeps the low
center inland of the Seward Peninsula. The GFS eventually pins the
low on the ECMWF location by Tuesday morning though.

Very cold air over the West Coast will continue to create snow
squalls over the Bering Strait through most of the week. Winds
continue to weaken over the West Coast through the week.

Deep low near Valdez with occluded front pushing north over
Western Canada and Eastern Alaska with return flow over the
Eastern Interior will persist through the day. Return flow over
the very cold air in place is creating an overrunning situation
for today. This has prompted advisories over much of the Northern
Interior.

The ridge of high pressure over the Arctic Slope extending from a
ridge in far Eastern Russia combined with the deep surface low in
the Gulf of Alaska is resulting in a tight pressure gradient over
the southern slopes of the Brooks Range. This will create wind
chill advisories over much of the Western Interior and all of the
South Slopes of the Brooks Range.

Snowfall amounts in the Interior could be substantial as
advisories have been issued for many locations in the Interior for
heavy snowfall.
