Upper level Low Pressure (Shaded “Oval” shape, then “U” shape) has replaced the high pressure returning the much cooler onshore airflow. A weak cold front returned the chance for showers. Another frontal system (position shown is Monday) will move in Sunday increasing our rain chances. Football forecast for the Ducks Spring Game Saturday. Kickoff 11:00 AM- Mostly cloudy 55 degrees warming to the low 60s by the end of the game- just a slight chance of rain, rain chance increasing to a 40% chance in the afternoon, so it probably won’t rain at Autzen Stadium during the game.
