The authors thank Mike Biggerstaff, David Dowell, Ted Mansell, Alan Shapiro, Jerry Straka, and Conrad Ziegler for their assistance and comments. Three anonymous reviewers also provided helpful comments that improved the manuscript. This study would not have been possible without the participants in the TELEX field program, who persevered to collect data on this, the final storm of the campaign. This research is based upon work supported by NSF Grant ATM-0233268, as well as by a National Science Foundation Graduate Research Fellowship and an American Meteorological Society Industry/Government Graduate Research Fellowship held by the first author.
