Cross-state travelers on the Thanksgiving weekend will see a reduced chance of snowfall, but should be prepared for temperatures well below freezing, even during the day.

Cross-state travelers on the Thanksgiving weekend will see a reduced chance of snowfall, but should be prepared for temperatures well below freezing, even during the day.

But before that, the most dangerous conditions on Washington’s major mountain passes could come late Monday, as up to nine inches of snow, combined with gusty north winds, could send blowing snow across the highways and drive the windchill down to minus-10 degrees, according to the National Weather Service.

Tuesday is expected to be drier — clear and cold in the mountains, with afternoon pass temperatures between 9 and 14 degrees.

A chance of light snowfall returns to the forecast Wednesday, and there’s a chance of mountain snow on Thanksgiving Day. But National Weather Service meteorologist Dennis D’Amico said forecasts don’t indicate heavy, sustained snowfall during the long holiday weekend.

Temperatures are forecast to gradually rise after Tuesday, with periods of snow or rain in the mountains from Thursday night through Sunday.
