Alaska. Warm front moving over the ridge will impact will produce
relatively strong winds along the Northwest Arctic coast. Hence a
blizzard warnings along zones 205 and 201.
The front will stall across the Arctic slope and will likely cause
advisory level conditions over the Arctic plain and through the
passes in the Brooks range along with points east of zone 201.
Temperatures aloft will continue to warm through the weekend in
northern Alaska. However the next upper level cold trough is
poised to strike northern Alaska early next week for another
possible deep freeze to continue through much of next week.
Some flurries in extreme southeastern portion of Mainland Alaska
will dissipate by early Friday morning. The next possible chance
for any precipitation south of the Brooks range would be sometime
early next week as the deep cold trough aloft moves eastward
across the state from the northwest. This trough is followed by
another ridge aloft which quickly loses out its influence as the
next much stronger upper level trough moves down and squashes the
