An outflow boundary from a large complex of thunderstorms that tracked across Iowa and northern Illinois the night before dropped southward on July 24th.  Convection developed along this boundary, with a bow echo eventually taking shape across northern Missouri.  As these storms moved into west-central Illinois, numerous reports of wind damage were received.  Additional thunderstorms developing behind the initial line led to a heavy rain event during the evening and overnight hours, with many locations picking up between 2 and 4 inches of rain.
