Northern Alaska Forecast Discussion...CORRECTED
National Weather Service Fairbanks AK
528 AM AKST Sun Jan 21 2018
.DISCUSSION...

Models in fair agreement through 60 hrs before diverging slightly
on trough placement over the state. General model consensus keeps
the longwave trough over Northern Alaska and a high pressure ridge
over the Bering Sea and West coast. To the east of the trough, 
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...Wind Chill Advisories remain in
effect for portions of the Brooks range Passes through 6 pm before
winds diminish below 15 mph. Winds have dropped off enough to
cancel zone 204 wind chill advisory. Still cold wind chills 
around 55 below in zone 203. Advisory out until noon as winds
should decrease below the advisory threshold late this morning. 
Temperatures will remain near to below normal through the forecast
period with some warming hinted late next week by the models. 

Eastern and Central Interior...Temperatures from Fairbanks
east will gradually drop around 25 to 30 below Sunday morning. 
Temperatures are expected to remain in the 20 to 30 below range 
in the Fairbanks area through most of next week with mostly cloudy
skies and flurries/light snow. Light accumulations expected. The 
cloudy conditions will help keep temperatures from bottoming out 
even further through Tuesday. 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. 

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. Wind chill for most
areas around 35 to 40 below. Winds will remain below 15 mph for
most areas. Below normal temperatures will persist across the 
region throughout the forecast period with model guidance hinting 
at a gradual warmup mid to late next week. 

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