…COLDER AND WET CONDITIONS EXPECTED THROUGH THE WEEKEND…

A large upper level low pressure area is approaching the region
and will linger through the weekend. Significantly cooler
conditions will enter the interior Pacific Northwest. Rain and
snow will be mainly over the Cascades and Oregon on Friday with
snow levels between 2500 and 4000 feet. A break in the widespread
precipitation is expected Saturday and then another system with
precipitation and even colder air will arrive Saturday night and
Sunday. Snow levels will lower further to 500 to 1000 feet in
Washington and 1000 to 2500 feet in Oregon. Accumulating snow can
be expected at the higher pass levels, with the first snow 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 lowest
elevations of the Columbia Basin, with a chilly rain prevailing.
Travelers to the higher elevations should be prepared for reduced
visibility in snow, and for slick roadways.
