A potent upper-level low approached the area from the Mississippi Valley as low pressure developed along the North Carolina coastline and moved north. Heavy precipitation (some of which fell in the form of snow) overspread the area during the morning of the 15th and lasted through the mid-afternoon hours, leading to some localized instances of flooding.
