The National Weather Service says a series of storms are headed for the Northwest that will bring waves of rain with short breaks through the weekend.
Forecasters say a storm blowing into Washington Thursday night and Friday will bring rain to western Washington and snow to the mountains. It also will bring snow or freezing rain to parts of eastern Washington that will persist through the weekend.
The recent mild weather systems that blew through Washington have left little snow in the Cascades.
Starting Friday, Amtrak Cascades plans to add a third daily round trip train between Seattle and Bellingham to help travelers affected by the May 23 collapse of a section of an Interstate 5 bridge over the Skagit River at Mount Vernon.
Forecasters say two weather systems Monday and Tuesday will drop up to 3 feet of new snow in the Cascades by early Wednesday, making driving difficult through the mountain passes.
Forecasters say Monday’s snow in the mountains and Eastern Washington could be followed by a stronger system Tuesday night that could drop an inch or two of snow by Wednesday night in the higher locations of the Western Washington lowlands.
Forecasters say snows are easing off Thursday in Western Washington and the Cascades but continuing in Eastern Washington.
The National Weather Service says the lowland snow showers in parts of Western Washington on Wednesday morning will turn to rain with high winds on the coast and northwest interior until Wednesday evening.
Some parts of the region are seeing their first snowflakes of the season. The National Weather Service says the light Tuesday morning accumulations will be short-lived but more showers are possible Wednesday with a chance of high winds in places.
The National Weather Service says the Western Washington lowlands could get up to 1 inch of rain with 1 to 3 inches likely in the mountains.
