.SYNOPSIS...
An active pattern is expected for the southern Interior through
the end of the work week with a couple rounds of snow moving
through the area, primarily to the south of the Yukon River. Very
cold temperatures are anticipated for tonight for the North Slope
as well as the Northern Interior (mainly to the north of the Yukon
River).

.DISCUSSION...
Upper Levels and Analysis...
Aloft, at 500 mb, zonal flow is in place over much of the forecast
area today. A shortwave trough that is currently in place over the
lower Yukon Valley will continue to push to the east tonight as a
second trough moves across the north slope. The flow aloft over
the Interior will become more southwesterly for Thursday and
Friday as a trough strengthens over the northern Bering Sea and
the Southern Chukchi Sea.

Model Discussion...
The models have some minor difference with the current active
weather situation over the Interior. We stayed away from the GFS
because it was a bit of an outlier in terms of the placement of
the precipitation (it was a bit too far to the north). We
utilized high resolution guidance for our QPF forecast today,
which had the effect of cutting down on snowfall totals to some
degree from the inherited forecast grids.

North Slope and Brooks Range...
Very cold wind chill values along with blowing snow are the main
concern in the short term. This is due to an Arctic trough that
has brought increased westerly winds to the Beaufort Sea Coast
today. The breezy westerly winds will continue tonight before
diminishing tomorrow. Wind chill values as cold as -60 are
possible along the Beaufort Sea Coast into Thursday. Otherwise,
cold temperatures will remain in place over the area.

Central and Eastern Interior...
Snowfall will continue this evening, mainly to the south of
Fairbanks. A short reprieve Thursday followed by another round of
snow that moves in Thursday night into Friday, bringing more
accumulations in the 3-6" range, with amounts up to 12" along the
southern slopes of the Alaska Range. This system will also bring
areas of blowing snow over the summits north of Fairbanks along
the Dalton, Elliot, and Steese Highways, reducing visibilities to
one half mile or less at times.

West Coast and Western Interior...
Along the capes and in Norton Sound, the story will continue to be
strong northeast offshore winds, which will keep wind chills into
the -45 to -50 F range well into Friday. The system that brought
snow to the Yukon Valley today will gradually taper off this
evening. A short break then another round of snow comes late
tonight and into Thursday with an additional 2-6" possible as far
north as the Middle Yukon Valley and eastern Norton Sound, with
amounts approaching 8" around McGrath.

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

Extended Forecast for Days 4 through 7...
There is potential for another snowstorm to move from west to east
across the area early next week. The GFS brings this system
through much faster than the other operational  models. We will
have to continue to monitor this system.
