“Thanksgiving weekend is one of the busiest times for travel,” said ODOT District 13 Manager Ace Clark. “We will have crews on the highways day and night plowing snow, applying sand, salt and deicer as appropriate, and monitoring conditions. Please plan extra travel time, be prepared for winter weather and drive according to conditions of the road. We want everyone to get to their destination safely.”

According to an ODOT press release, high pressure that has brought the dry weather with areas of fog the past week is weakening and will allow a frontal system to approach the area Wednesday night and Thanksgiving.

The first in a series of Pacific fronts will arrive Wednesday night and Thanksgiving. There will be rain and mountain snow (snow levels around 3,500-4,500 feet), but also a slight potential for freezing rain early Thanksgiving morning in the low elevations where trapped cold air will be difficult to scour out. Snow levels will decrease Thursday night and Friday with a stronger frontal system that will bring rain and snow (snow levels around 3,000-4,000 feet) and also gusty winds.
