We thank Dave Gochis and two anonymous reviewers for their helpful reviews. One anonymous reviewer suggested conditionally sampling the linear fit between CAPE and rainfall. Thanks to Drs. Bob Maddox, Nilton Rennó, and Patricia Sánchez Lizardi for their comments on earlier drafts. Much of this work was carried out during the first author’s stay at the Departamento de Ciências Atmosféricas, Universidade Federal de Campina Grande, Paraíba, Brazil. Special thanks go to the UFCG graduate students of Convecção na Atmosfera.
