An upper-level disturbance interacting with a stationary frontal boundary draped across central Illinois triggered clusters of strong to severe thunderstorms during the afternoon and evening of May 19th. Some of the cells produced flash flooding and hail as large as ping pong balls near Long Creek in Macon County, while others caused isolated flash flooding in parts of rural Douglas County.
