The wider storm

A series of winter systems moved through the region starting Thursday Jan. 11th through Saturday Jan. 13th, and produced moderate to heavy snow across much of the forecast area. Persistent northwest flow aloft also sustained snow showers across the mountains between the systems. The second system was far more productive, with many lower elevation areas seeing 4-7 inches and locally higher of additional accumulating snow during this period of time.
