An east wind is pushing arctic air from the central U.S. to the Pacific Northwest. Temperatures have plummeted in the last couple of days.
The cold front is forecast to bring snow to the mountains and central Oregon and even into the Willamette Valley overnight and into Thursday. Laurel McCoy is a meteorologist with the National Weather Service in Portland. She says the snow isn't likely to stick around in the South Willamette Valley. But it's good news for Oregon's ski areas.
McCoy: "Up in the mountains they could see as many as six to 9 inches in some areas. This will be great for getting some snow-pack on those mountains."
More snow is forecast for central Oregon as well. And north of Salem.
High winds knocked down trees in the Portland area causing thousands of power outages Wednesday morning.
