(PORTLAND, Ore.) - Cold air in place over the Northwest today will bring snow to coastal areas of Washington and Oregon, while the Santa Ana winds in Southern California begin to ease.
The mix of the cold air and the latest Pacific storm moving onshore today will produce snow west of the Cascades, including Seattle, Washington, and Portland, Oregon.
The Accuweather.com Winter Weather Center reports as much as three to six inches of snow could fall today in Portland, with as much as a foot forecast in parts of the Cascades.
Heavy snow in the Northwest has created treacherous driving conditions, especially in mountainous areas.
Meanwhile, a strong pressure gradient between the low in the Northwest and high pressure over the Four Corners has resulted in two days of strong Santa Ana winds in Southern California.
