Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK
443 AM AKST Mon Jan 22 2018


Models in fair agreement through 60 hrs and beyond with slight
differences in the upper low placement after 60 hrs. A Cold 506
dam upper level low center over Barrow will sink down over the
center of the state and weaken slightly to 508 dam by Wednesday
morning then deepen again as it moves near Kodiak Island. General
model consensus keeps the longwave trough over Northern Alaska and
a high pressure ridge over the Bering Sea and West coast. Ridging
will persist over the Bering and west coast through next weekend.
To the east of the upper low, cloudy conditions will continue to
help moderate temperatures, while to the west predominately clear
skies will allow for strong radiational cooling and will produce
colder temperatures.

Arctic Coast and Brooks Range...Winds have dropped off enough
over the slope so there are no wind chill advisories this morning.
Some areas are still close to 50 below wind chills. Cold
temperatures persist where it is clear. 35 below around Deadhorse
this morning. Cold temperatures and areas of stratus will persist
into Tuesday.

Eastern and Central Interior...Fairbanks dropped to 30 below
yesterday morning due to a few hours of clear skies. This was the
coldest temperature so far this winter in Fairbanks. Temperatures
in Fairbanks area expected to remain cold through the week, with
temperatures between 15 and 30 below zero. Skies are expected to
remain mostly cloudy through the week over the interior with
flurries/light snow. Light accumulations expected. The cloudy
conditions will help keep temperatures from bottoming out even
further through Wednesday. West of Nenana, where skies have
cleared out, temperatures will fall into the 30s below this
morning, and then remain between 30 and 40 below through most of
this week. The gradient does tighten up over higher terrain across
much of the northern AK as the upper level low drops down near
Kodiak and deepens. This will have to be watched for potential
wind chill issues.

West Coast and Western Interior...Maximum radiational cooling
under generally clear skies will allow for temperatures to drop
into the 30s and 40s below this morning. Currently Huslia and
Bettles near 45 below with ice fog. Winds are light but could
still produce very low wind chills with these temperatures. Winds
are still fairly strong along the coast and there is a wind chill
advisory for zone 210 through 6 pm this evening. West winds 15 to
25 mph will persist through the day. Winds will remain below 15
mph for most areas. Below normal temperatures will persist across
the region throughout the forecast period.

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


Wind Chill Advisory for AKZ210.
