A building pressure and thermal gradient will build up over the
Chugach and Talkeetna Mountains through late Saturday resulting in
strong winds over the Matanuska Valley. Sustained winds will
increase to 35 mph by late tonight, with wind gusts possibly getting
up to 60 mph. The main corridor of strong winds will occur over
Wasilla and western portions of Palmer, though changes to the
pattern could briefly pull the winds further south and east. These
conditions will last into Saturday before subsiding as the gradient
over the mountains begins to lessen.
