APPENDIX

Appendix contains images of radar reflectivity, annotated with the boundary used to control the automated computation of the echo centroid, which is denoted with a black dot. The label next to the black dot contains information used by the analyst for record-keeping and is not of relevance to this paper.  The purpose of the appendix is to allow others attempting to repeat this work to make sure that the same storms are being analyzed.

Figure A1. Reflectivity analysis plots for the Plainview storm on 25 May 1994 from the KLBB WSR-88D radar. Rain rate centroids are depicted with a dot and are labeled from left to right identifying the maximum reflectivity, average reflectivity, latitude, and longitude at the map height of 2.16 km. References to panels in the text refer to panels counted from left to right and then top to bottom.
