Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK
256 PM AKST Sun Jan 22 2017

.DISCUSSION...
Models in decent agreement through 60 hours. Long wave trough over
Mainland Alaska will continue to shift north as large upper level
ridge builds in from the East from Canada but originating from the
West Coast of the US.

Very strong 944 mb low in the Western Aleutians will continue to
move towards Dutch Harbor and then stall and then recurve to the 
Northwest. Besides some moderate winds from the Saint Lawrence
Island area and south, there doesn't seem to be too much to impact
Western Alaska.

Cold air continues to funnel out of the Brooks Range and northward
which continue to create winds just strong enough along the Arctic
Coast to warrant Wind Chill Advisory.

The washed out occluded front from the large low will spread snow
over the Southwestern portion of the State and then spread it 
north to the Seward Peninsula by Tuesday morning. All of the 
precipitation amounts look fairly light at this time.

Chinook flow will develop over the Central Interior and produce
some decent gap flow winds beginning Monday and then continuing
through Wednesday. Expect some wind advisories for this time 
frame to come up a little later.
