A prolonged period of thunderstorms occurred over the Owensboro area in a very moist southerly wind flow. A weak low pressure center just northwest of the Ohio River's confluence with the Mississippi River helped to focus the moisture and convergence. A 500 mb shortwave rotating northeast across the Lower Ohio Valley further aided the storms.
