An Upper Level Low Pressure Trough (Shaded “U” shape with blue arrows) has taken control of our weather. The graphics for days days 1-3 show the next frontal system that pushed through Oregon Monday. The graphics for days 3-7 show the complex frontal system move across the Pacific Northwest Friday bringing colder air and the threat of a dusting of snow above 1,000 ft. then another front moving in between late Monday (Christmas Day) and Tuesday morning. So far no snow accumulation is expected across the South Willamette Valley.
