Large upper level low pressure will move south from the Gulf of
Alaska, approaching the region by Friday, lingering through the
weekend. Significantly cooler conditions, along with widespread
precipitation, will enter the interior Pacific Northwest by
Friday, persisting through the weekend. Snow levels will fall to
between 2500 and 4500 feet Friday, lowering further to 1000 to
2500 feet by Sunday. Accumulating snows can be expected at the
higher pass levels, with the first snows of the season possible as
low as the valley floors. Some accumulating snow is possible for
the Yakima and Kittitas Valley Saturday Night and Sunday.
Accumulating snow is not expected for the lower elevations of
Oregon, with a chilly rain prevailing. Travelers to the higher
elevations should be prepared for reduced visibility in snow, and
for slick roadways.
