The State Climate Office of North Carolina has an interesting look back at a storm in May 1992 which brought heavy snow to parts of the southern Appalachian Mountains. I remember this storm well because I was spending three weeks in Asheville NC at the National Climatic Data Center looking for historical climate data for Wisconsin. It rained for an entire week under a cut-off low which parked over the area and dropped a lot of precipitation. Up at higher elevations it was all snow, and some areas got several feet of snow from the storm. You can read more about it at https://climate.ncsu.edu/climateblog?id=234&h=37a460a0.
