.DISCUSSION...
Active Weather over Northern Alaska. A strong front extends south
along the west coast from a 994 mb low near Wrangel Island.
Moisture ahead of the front continues to move east into the
western interior early this evening and into the central interior
later this evening and tonight. Southwest flow from the surface
to the mid levels of the atmosphere ahead of the front continue to
produce heavy snow in the western Brooks Range and Seward
Peninsula where Winter Storm Warnings and Winter Weather
Advisories remain in effect into tonight. Freezing rain is
expected to move inland as temperatures aloft rise to around zero
to 4 below over the YK Delta and locations south of Unalakleet. Up
to one tenth of an inch of ice accumulation is expected in these
areas and 4 to 7 inches of snow is expected in the Nulato Hills.
Winter Weather Advisories have been extended in these areas
through Thursday evening.

Winter Weather Advisories have also been issued over the central
and eastern interior as well as the southeastern Brooks Range
where 4 to 7 inches of snow is expected to fall beginning tonight
and continuing into Friday. Strong northwest flow behind the
front will enhance the up slope flow in the Alaska Range where up
to a foot of snow is expected, especially to the west of the Parks
Highway.

As the surface low near Wrangel Island moves south and east over
the North Slope tonight and Thursday heavy snow and blowing snow
will continue over the north slope. West and northwest winds will
enhance snowfall along the northern slopes of the Brooks Range.

Strong northwest winds develop tomorrow over St Lawrence Island
with wind gusts to 65 mph expected to develop Thursday afternoon
and will continue into Thursday evening. Strong west to northwest
winds will also develop over the southern portion of Norton Sound
as well as the lower YK Delta where a long fetch and sustained
winds will produce high surf in eastern Norton Sound as well as
the lower YK Delta coast into Friday.

The 12z model suite initialized well against the 12z surface
analysis and verified well against the 18z surface analysis. Model
spread continues to be minimal in the short range and but
increases substantially in the mid range with significant
positional differences on a low moving southeast through the
eastern Bering Sea Sunday. Model spread continues to increase
through the extended range.
