Relatively quiet period as high pressure builds over the West
Coast of Alaska. An upper level trough moving across the Central
Interior will continue to bring snow showers through this evening
into tomorrow, but will then diminish across much of Central and
West Coast of Alaska. Main concern and focus will be developing
blizzard conditions late tonight across the Eastern Beaufort Sea
coast with strong winds continuing through noon Wednesday. 

Arctic Coast and Brooks Range...Blizzard conditions are expected 
to return across the Eastern Arctic Coast along the Beaufort Sea 
coast. Pressure gradient will begin to tighten tonight with winds
west winds of 25 to 35 mph and gusts up to 50 mph expected. The
combination of snow and strong winds will reduce visibilities to 
to less than quarter mile, especially for area with with the 
fresh snow across the area. Expecting winter weather advisory 
conditions Nuiqsut through Deadhorse has the winds will increase
across the area as well but perhaps not as strong. However the
combination of wind and temperatures will allow wind chills to
reach 50 to 59 below. Strongest winds to occur for areas between
from mid morning through tomorrow evening.

Western Interior and West Coast...Isolated snow showers will
continue to diminish through the afternoon as the ridge of high 
pressure builds overhead. Expecting snow to taper off and for 
conditions to improve. Temperatures will drop 15 to 20 degrees 
across the region and will remain below normal through late this 

Eastern and Central Interior...Decent snow band moved from Nenana
through Fairbanks and Eielson bringing decent snow of half of an
inch to an inch and reduced visibilities to quarter mile at 
times. This snow band will continue to move northeast across 
Middle Tanana Valley through the late afternoon. Snow will 
persist across the region through Tuesday morning. There will be a
gradual cooling trend over the next few days, then a dramatic 
drop in temperatures to below normal temperatures as skies clear. 
Interior valley locations could possibly see overnight lows 25 
below to 35 below by Thursday morning. Many of the models indicate
colder temperatures heading into next weekend, with the 
temperatures from the North American Ensemble Forecast System 
(made of GFS ensemble forecasts and Canadian ensemble forecasts) 
showing 3 standard deviation colder across Central and Eastern 
Interior Alaska by next Monday than climatological normals. This 
could be mean 35 to 45 below temperatures are possible in the 
colder locations in Eastern Interior by weekend.
