The authors gratefully acknowledge S. Yuter for assistance with the visualization and analysis of the MRR imagery. In addition, Jason Endries helped with some of the figures for Poga Mountain snowfall rates. NWS cooperative observers, CoCoRaHS observers, law enforcement and emergency management officials, and the public provided snowfall reports that aided in the documentation of this event. The Roan Mountain observations are based upon work supported by the National Science Foundation under Grant EAR 0949263. We also appreciate the very helpful manuscript reviews from colleagues at the National Weather Service Eastern Region Headquarters, Scientific Services Division, as well as those of three anonymous formal reviewers, which all helped to significantly improve the paper.
