SEATTLE (AP) — The National Weather Service says Arctic air blowing into the Northwest on gusty winds Tuesday will drop temperatures below freezing in many locations.
That sets up a chance of snow Wednesday and Thursday as a moist weather system moves into the region from the southwest.
Forecasters say snow is likely in the Columbia River Gorge and Hood River Valley and possible across the Portland-Vancouver area. A rain-snow mix is possible in southwest Washington south of Puget Sound. The first significant lowland snow of the season is possible in Eastern Washington.
