Review of August 4 storms: Wind damage, heavy rain, large hail, and two EF-0 tornadoes

A very humid and unstable atmosphere set the stage for widespread thunderstorms that produced heavy rain and local wind damage. Though there were isolated storms during the midday hours, the main severe storm complex evolved over southern Illinois around 4 P.M. The first severe weather report of the main event was a wind gust to 70 mph clocked at the Carbondale airport at 4:29 P.M. In anticipation of the increase in storms, the Storm Prediction Center issued Severe Thunderstorm Watch 658 at 3:10 P.M.

Over 30 reports of wind damage, funnel clouds, flash flooding, and hail were received by the Paducah NWS office in a 5-hour period ending at 9 P.M. A "bow echo" produced widespread wind gusts from 60 to 70 mph in a swath from the Carbondale and Harrisburg, IL areas, southeast across the Ohio River, to Hopkinsville and the Lakes Region of western Kentucky. Serious flooding occurred in Cape Girardeau, where numerous water rescues were conducted. A couple of weak tornadoes occurred in Christian County.
