Are you heading north on I-5 toward Eugene or Corvallis or Portland Friday into Saturday?
Get there before Friday evening because warm, moist air will move over very cold air at the surface Friday night through Saturday night and this will bring a near ideal set up for freezing rain and sleet north of Roseburg, but especially the Willamette Valley. This will cause a significant risk of dangerous travel conditions due to icy roads. Please check the latest forecasts and view road conditions at tripcheck.com before you leave. Via NWS Medford
