Short lines of thunderstorms with embedded circulations moved across southern Illinois during the afternoon of the 19th. Widespread heavy rain caused isolated flash flooding. The storms occurred just south of a warm front under a very strong southwest low level flow, around 60 knots at 850 mb. An upper level disturbance over the Ozark Mountains contributed to the storms.
