A long-duration snowfall occurred on December 11.  A low pressure system over the Central Plains moved northeast over Lower Michigan, bringing good moisture to the region.  With cold air in place, the precipitation fell as all snow through the entire event. Snow began as a dry and fluffy type with temperatures in the lower 20s during the morning hours.  Temperatures then slowly rose into the lower 30s during the afternoon and evening hours, causing the snow to become wetter.
