Here we snow again: Slick mountain passes, frosty in valley

EUGENE, Ore. - Travelers should expect wintry conditions in the mountains as the lower elevations brace for the first frost event of the season.

Forecasters expect 2 to 4 inches of snow above 2,000 feet Friday afternoon into Saturday, with snow and ice making for slick conditions on mountain passes.

And the Willamette Valley could see the first widespread frost of the fall Friday night and Saturday as cold air continues to move into the region.

"With a slightly cooler air mass in place coupled with the clearing skies, the potential for more widespread frost and local freeze conditions exists," the National Weather Service said Friday. "Snow and ice will create hazardous driving conditions on area roads and highways including Interstate 5 at Siskiyou Summit, Highway 58 at Willamette Pass and Highway 138 at Diamond Lake Summit."
