Figure 17. This is a loop of composite reflectivity and storm total precipitation (STP) from 2242 UTC 6 April 2003 until 1042 UTC 6 April 2003 (every 1.5 hrs) from  KDGX. The loop shows the evolution of the second longer-lived MCS and the resulting rainfall pattern. Notice that the initial STP image indicates rainfall from the earlier MCS. is the U.S. government's official web portal to all federal, state and local government web resources and services.
