Portland, OR -

Oregon's weather is going to get worse as the weekend approaches and the western U.S. cold snap is followed by snow.

The National Weather Service forecasts significant snow in the south and east on Friday and some of the coldest temperatures in recent years in the northwest.

On Friday, southwestern Oregon cities are expected to see snowfall ranging from 3 to 6 inches and accumulating on roads.

The forecasters say northeast and much of Central Oregon can expect several inches of snow Friday and Saturday, with cold temperatures persisting into next week.

Arctic air is expected to mean low temperatures in the teens and lower beginning Friday and lasting through the weekend in northwest Oregon and the Columbia Gorge, where wind gusts could reach 60 mph.
