The authors greatly appreciate the detailed damage surveys provided Greg Stumpf, Gabe Garfield, and Doug Speheger, and others who contributed to the 10 May 2010 and 24 May 2011 damage surveys. The detail provided in these damage surveys was critical for making comparisons between the observed damage and polarimetric radar observations. Discussions with Chris Schwarz, Daniel Betten, Conrad Ziegler, Jim Kurdzo, Steve Ansari, and Clark Payne were also helpful in this analysis. The authors are also thankful to Paul Schlatter and Les Lemon for reviewing an early draft of the manuscript. The authors also appreciate comments from three anonymous reviewers, which were particularly helpful in improving statistical aspects of the paper and comparisons of the EF scale to TDS parameters.
