models in decent agreement through about 48 hours. Upper level
ridge will begin to break down over the northern portion of the
forecast area...around the Arctic coast and the Brooks range as
the cold front crashes in to the Arctic coast. This will turn all
precipitation to snow.
Freezing rain pockets still around the interior but will soon
evaporate over night with the cold air intrusion. Behind the cold
front...the main push from the Arctic front will push southward
over the state and return northern Alaska to more respectable
temperatures for winter along with frozen temperatures. New model
run shows a decrease in quantitative precipitation forecast amounts over most of the area with the
advance of the Arctic front.
With the advance of the cold front tonight and the Arctic front
close on its heels...the surface low will push eastward rather
rapidly and as it does...strong west winds will last through early
afternoon in the eastern Arctic.
Coastal hazard potential days 3 and 4...none
