Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK
301 PM AKST Fri Feb 23 2018


The low pressure system that caused very active weather for our
forecast area the past few days has pushed east into Canada.
Behind it northwesterly flow aloft will bring cooler, more
seasonal temperatures to our forecast area this weekend. This
cooling flow is the result of a low in the arctic pumping colder
air into the state. A series of shortwave ridges and troughs will
move in quick succession across the southern half of the state
over the next few days. The weather on the surface will reflect
conditions aloft. The upper level pattern of ridges on troughs
moving across the southern half of the state are reflected on the
surface as shortwave surface highs and lows. Models remain in good
agreement until early next week on this pattern.

Central and Eastern Interior...The bulk of the weather has passed
through the Interior. Some gusty winds and snow showers remain
mainly south and east of Fairbanks and will linger through the
afternoon. As of 3PM local time, satellite shows a clearing line
just west of Fairbanks and slowly moving east across the middle
Tanana Valley. Close to the ALCAN border weather there is clearing
as well, with some snow showers lasting into the evening. Cooler
temperatures will work their way in from the northwest the next
few days, bringing temperatures closer to normal over the weekend.
Not too cold though as most places will see highs around 10 above
and lows around 10 below.

West Coast and Western Interior...Northerly flow will keep winds
brisk along the coastlines through tomorrow afternoon with gusts
up to 25 mph for most locations, except for St. Lawrence Island
which will see gusts up to 40 mph. A low pressure system moving
west to east across the southern Bering Sea will bring a chance of
snow to the Y-K Delta and Lower Yukon Valley tonight and tomorrow.
It is moving quickly though so weather should exit both areas by
Sunday...only for the next round of snow to begin early next week.

North Slope...Typical winter conditions prevail for the western
and central North Slope and will continue to do so for the next
few days. A blizzard has developed as anticipated around Kaktovik.
High winds along the eastern arctic coast are more widespread
than first anticipated and have produced blizzard conditions for
most of the eastern arctic coast to include Deadhorse and
Kuparuk. Blizzard conditions will continue until Sunday, with a
brief lull in blizzard conditions Saturday...though gusty winds
and reduced visibility will still be present.

Brooks Range...Northwest flow out of the arctic coupled with an
area of high pressure moving into the Interior has induced a
gradient across the Eastern Brooks Range. As a result, gap winds
out of the north have developed producing wind gusts around 30 mph
in passes including Atigun and Anaktuvuk. These winds will be
intermittent over the next few days as the gradient will slacken
and redevelop at times.

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


Blizzard Warning for AKZ204.

Winter Weather Advisory for AKZ220.

Heavy Freezing Spray Warning for PKZ210.

Gale Warning for PKZ210-PKZ245.

Brisk Wind Advisory for PKZ200-PKZ235-PKZ240.
