Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK
245 PM AKST Wed Feb 21 2018

A weather system over western Alaska will move east across
mainland Alaska through Friday and be the significant weather
maker during the next 48 hours. This system is bringing snow and
freezing rain from the Seward Peninsula southward and the western
Interior south of Galena. Mixed precipitation is expected to
reach as far east as Fairbanks tonight. Periods of heavy snow will
also impact the Interior. Strong west winds and colder air will
trail behind the low late Thursday into Friday resulting in
blowing and drifting snow over the west coast and much of the
Interior from the Brooks Range southward. Temperatures will fall
to near normal for the weekend.

A broad ridge aloft over the north Pacific is bringing moist west
to southwest flow to mainland Alaska along with warm air and above
normal temperatures. This ridge will be suppressed and pushed
east into Canada on Thursday as a sharp trough aloft currently
over the Bering Sea progresses across the state into Friday.
Current forecasts are on track and we have only made minor
increases to the snowfall totals in the Interior and also bumped
up the strong winds developing in northwest Alaska on Thursday.

At the current time, it appears the chance for freezing rain will
remain from Fairbanks west. Periods of snow will continue into
Friday with amounts from 3 to 8 inches south of the Brooks Range,
with some locally higher amounts in favorable westerly facing
slopes. Gusty winds with the cold front Thursday through Friday
will pose the most significant impact. Visibility will be reduced
in many locations due to blowing and drifting snow, even at many
valley locations in the Interior.

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