Deaths: 0
Injuries: 0

What happened

The episode as NWS PAH wrote it up.

Thunderstorms increased in coverage and strength during the late afternoon in a zone of strong instability along the southern edge of the westerly jetstream. Thunderstorms that occurred over Illinois and Indiana earlier in the day left an outflow boundary that extended from west-northwest to east-southeast across southeast Missouri. This boundary enhanced thunderstorm development. Rich low level moisture and steep lapse rates fostered isolated severe weather events until the atmosphere stabilized toward sunset.

What forecasters said that day

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Paducah, KY wrote its last area forecast discussion before the first event at Sep 5, 2:08 PM CST, 2 minutes earlier.
