An upper level low will keep the airflow over the Pacific Northwest from the South and Southwest (see the little arrows) and that means rain. Eugene tied the record low yesterday dropping to 30 degrees because of the clear skies. Not as cold this morning because the clouds radiate more energy back to the ground. Clear skies allow for  radiational cooling meaning the radiation escapes away from the surface and spreads out and upward dropping the surface temperatures. Look for lots of clouds and rain today and Wednesday with highs near 60. There will be a chance of rain Thursday and just a slight chance Friday as high temperatures slowly rise to the mid 60s. More storm systems will give us the chance of rain for the weekend into early next week. The coast will be similar to the Willamette Valley while Roseburg will be a bit warmer Thursday and Friday.
