A strong Alaskan low will usher unseasonably cold air into southwest Washington and northwest Oregon likely lingering through the weekend. Accumulating snow is possible at any elevation into Saturday morning. However, the chances of receiving 1 inch or more of snow remain around 20 to 30 percent for any given location in the interior lowlands during these times including the salem – keizer area. Snow will be most likely to accumulate during the late night and early morning hours, when ground temperatures are the coolest.
Meanwhile, a winter storm warning remains in effect until five tomorrow afternoon for the North Oregon Cascades and the Cascades in Lane County. Heavy snow is expected. Total snow accumulations of one to three feet above 25 hundred feet and 10 to 15 inches below two thousand feet. Winds will gust as high as 40 miles per hour. Travel could be very difficult.,
